Description

This invention relates to a screen for preventing droplet infection.

Conventionally, various methods have been used to protect doctors from infected or suspected infected patients. For example, in a medical examination booth for examining patients, as disclosed in Patent Document 1, a fan device blows air to prevent droplet infection and to prevent infectious bacteria from the patient from being transferred to the doctor. However, because a fan device is required in the medical examination booth, the equipment becomes large and inconvenient to carry and move.

Patent No. 5263697

In view of the above problems, the present invention provides a partition for preventing droplet infection that is lightweight, foldable and small, easy to carry, and can separate a space for examining a patient.

In order to solve the above problems, the droplet infection prevention partition of claim 1 or 2 of the present invention is a droplet infection prevention partition composed of a hollow structure plate, and extending from the upper end to the lower end of the hollow structure plate, a bendable, approximately V-shaped or thin-walled inner first groove portion and inner second groove portion are formed, the hollow structure plate is divided into a main plate, a first side plate and a second side plate by the inner first groove portion and the inner second groove portion, a transparent plate is provided on at least a part of the main plate, and a tubular portion is joined to two through holes provided in the main plate.

According to the above features, the first and second side panels can divide the space into, for example, an approximately U-shape, making it easy to install anywhere and to easily provide an examination space that prevents droplet infection. Also, a doctor can examine a patient by putting his or her hand through the tube, so the doctor's hand can be smoothly put through the tube without getting caught on any part of the droplet infection prevention screen. Furthermore, by folding the first and second side panels, the entire droplet infection prevention screen can be made small and flat, making it convenient to carry and store without taking up too much space. Also, because the droplet infection prevention screen has a portion made of a hollow structure plate, it is light in weight and easy to carry.

Furthermore, the droplet infection prevention partition of claim 1 of the present invention is characterized in that, in the first side panel, a bendable, approximately V-shaped or thin-walled outer first groove portion is provided at a position adjacent to the inner first groove portion, extending from the upper end to the lower end of the first side panel, the width of the thin portion of the outer first groove portion is wider than the width of the thin portion of the inner first groove portion, and, in the second side panel, a bendable, approximately V-shaped or thin-walled outer second groove portion is provided at a position adjacent to the inner second groove portion, extending from the upper end to the lower end of the second side panel, the width of the thin portion of the outer second groove portion is wider than the width of the thin portion of the inner second groove portion.

The above features allow the resilience of the first outer groove portion when folded when the first side panel is folded by bending the first outer groove portion to be suppressed, and similarly, the resilience of the second outer groove portion when folded when the second outer groove portion is folded when folding the second side panel to be suppressed. In addition, by providing two bending points on each of the first and second side panels, the first and second side panels are easy to bend, and the entire droplet infection prevention screen can be folded compactly.

Furthermore, the droplet infection prevention partition of claim 2 of the present invention is characterized in that the tubular portion of the main body plate is attached so as to protrude toward the outside of the main body plate, the first side plate and the second side plate are capable of being bent toward the inside of the main body plate opposite the protruding direction of the tubular portion, and the glove attached to the tubular portion is positioned within the space surrounded by the main body plate, the first side plate and the second side plate, passing through the inside of the tubular portion.

According to the above features, the gloves are attached through the inside of the tube, so even if the doctor inserts his hands into the gloves through the tube to examine the patient, the gloves are unlikely to come off. Furthermore, when the first and second side panels are folded, the gloves are covered and protected by the first and second side panels, so they are unlikely to be damaged during storage or transportation. In addition, there is no gap between the patient and the doctor, so droplet infection can be effectively prevented.

Furthermore, the droplet infection prevention partition of claim 2 of the present invention is characterized in that the tubular portion of the main body plate is attached so as to protrude toward the outside of the main body plate, the first side plate and the second side plate are capable of being bent toward the inside of the main body plate opposite the protruding direction of the tubular portion, the tubular portion is installed within a through hole of the main body plate, and the end of the tubular portion is flush with the inner surface of the main body plate.

With the above features, the inner surface of the main body plate and the end of the tube are flush, so there are no protruding parts such as steps between the end and the surface. Therefore, when using the glove to examine, etc., it is possible to prevent the glove from being torn and damaged by protruding parts such as steps. In addition, when the glove is pulled outward through the tube after the examination is finished and discarded, it is possible to prevent the glove from being torn and damaged by protruding parts such as steps.

Furthermore, the droplet infection prevention partition of claim 2 of the present invention is characterized in that the main body plate and the tubular portion are made of the same resin, and the through hole and the tubular portion are joined by pouring the same resin as the resin into the boundary between the through hole and the tubular portion.

The above features ensure good adhesion between the tube and the main plate, allowing the tube to be firmly fixed. Furthermore, resin is poured into the boundary between the tube and the through hole, eliminating gaps at the boundary, which helps prevent droplet infection from the patient, as described below.

Furthermore, the droplet infection prevention partition according to claim 3 of the present invention is characterized in that at least one of the first side panel and the second side panel is colored.

The above features allow the patient's face to be hidden from view during the examination, protecting the patient's privacy.

Furthermore, the droplet infection prevention screen according to claim 4 of the present invention is characterized in that it is provided with a lid body that covers the upper part of the main body plate.

The above features also cover the patient's upper body, effectively preventing droplet infection from the patient.

The droplet infection prevention partition of the present invention is lightweight, foldable, compact, and easy to carry, and can be used to separate a space for examining a patient.

The following describes an embodiment of the present invention with reference to the drawings.

First, Fig. 1 shows the hollow structure plate 100 that constitutes each side plate of the droplet infection prevention partition of the present invention. Fig. 1(a) is an overall perspective view of the hollow structure plate 100, Fig. 1(b) is an enlarged perspective view of the corner area of the hollow structure plate 100, and Fig. 1(c) is a plan view of the hollow structure plate 100.

As shown in Figure 1, the hollow structure plate 100 constituting the side panel of the droplet infection prevention partition is a plate material cut into an approximately rectangular shape, and has a short side edge 110 and a long side edge 120. This hollow structure plate 100 is cut out to match the size of the side panel from a single large plate material with a hollow structure, so the internal structure of the hollow structure plate 100 is exposed at the end faces of the edge 110 and the edge 120, i.e., the cut surfaces. This hollow structure plate 100 is composed of a resin core material 130 with internal voids due to a honeycomb structure, a resin inner skin layer 140 provided on the front side of the core material 130, and a resin outer skin layer 150 provided on the back side of the core material 130. As described below, when the droplet infection prevention screen is folded, the inner skin layer 140 folds inward to become the surface that is hidden, and the outer skin layer 150 becomes the surface that is exposed to the outside when the screen is folded. Since the internal structure is exposed at the end faces of the end edges 110 and 120, it is preferable to apply end surface treatment to the end edges 110 and 120 to prevent injury to people's fingers when carrying the droplet infection prevention screen. In addition, since no frame or the like is attached to the outer periphery of the hollow structure board 100 and the entire screen is flat, it is easy to wipe the surface.

The core material 130 is a material with a hollow structure inside due to a honeycomb structure, but is not limited to this, and any other material made of resin with a hollow structure can be used. The hollow structure board 100 is composed of the core material 130, the inner skin layer 140, and the outer skin layer 150, but is not limited to this, and the hollow structure board 100 may be any other configuration as long as it has a resin hollow structure. The core material 130, the inner skin layer 140, and the outer skin layer 150 are preferably composed of a polypropylene material that can be washed with alcohol and has light-gathering properties. The materials of the inner skin layer 140 and the outer skin layer 150 are preferably made to contain an antibacterial agent or an antiviral agent to prevent the proliferation of bacteria and viruses. The hollow structure board 100 is approximately rectangular, but is not limited to this, and may be any shape according to the size and shape of the side panel. In addition, the surface of the hollow structure plate 100 is generally flat with few irregularities, making it easy to wipe off dirt, bacteria, viruses, etc., and hygienic.

The edge treatment will be described with reference to Figures 2 to 4. Figure 2(a) is a plan view of the hollow structure board 100 showing how the edge treatment is being performed, Figures 2(b) to 2(e) are side views of the vicinity of the edge 110 of the hollow structure board 100 showing how the edge treatment is being performed (side views seen from the arrow A shown in Figure 2(a)), and Figure 2(f) is a plan view of the hollow structure board 100 after the edge treatment has been performed.

First, as shown in FIG. 2(a), in order to perform edge processing on the edge 110 of the hollow structure plate 100, a heating plate 710, which is wider than the length of the hollow structure plate 100, is pressed from above the edge 110. In addition, since this heating plate 710 extends along the edge 110, edge processing can be performed on the entire edge 110 at once. Specifically, as shown in FIG. 2(b), the flat pressing surface 711 of the heating plate 710 is pressed from above against the inner skin layer 140 of the hollow structure plate 100. This pressing surface 711 is heated to a temperature at which the inner skin layer 140 and the core material 130 can be melted, so that the heating plate 710 presses the inner skin layer 140 downward, and as shown in FIG. 2(c), the inner skin layer 140 and the core material 130 are compressed while melting, forming the thin-walled portion 160. Next, as shown in FIG. 2(d), the thin-walled portion 160 is bent upward and brought into close contact with the end surface 131 of the core material 130. The end surface 131 is heated and melted by the heating plate 710, and the unevenness of the internal core material 130 melts to form a smooth surface. The thin-walled portion 160 is also heated and melted by the heating plate 710, so that the end surface 131 and the thin-walled portion 160 are firmly welded in close contact. Then, as shown in FIG. 2(e), the tip 161 of the thin-walled portion 160 protruding from the surface of the inner skin layer 140 is cut off, completing the end surface processing of the end edge 110. As shown in FIG. 2(f), when the end surface processing is completed, the internal structure exposed from the end edge 110 of the hollow structure plate 100 is blocked by the thin-walled portion 160.

Next, as shown in Figure 3, edge treatment is performed on the edge 120 of the hollow structure plate 100. Note that Figure 3(a) is a plan view of the hollow structure plate 100 showing how the edge treatment is performed, Figures 3(b) to 3(e) are front views of the vicinity of the edge 120 of the hollow structure plate 100 showing how the edge treatment is performed (front view seen from the arrow B shown in Figure 3(a)), and Figure 3(f) is a plan view of the hollow structure plate 100 after the edge treatment has been performed.

As shown in FIG. 3(a), in order to perform edge processing on the edge 120 of the hollow structure plate 100, a heating plate 720, which is wider than the length of the hollow structure plate 100, is pressed from above the edge 120. In addition, since this heating plate 720 extends along the edge 120, edge processing can be performed on the entire edge 120 at once. Specifically, as shown in FIG. 3(b), the flat pressing surface 721 of the heating plate 720 is pressed from above against the inner skin layer 140 of the hollow structure plate 100. This pressing surface 721 is heated to a temperature at which the inner skin layer 140 and the core material 130 can be melted, so that when the heating plate 720 presses the inner skin layer 140 downward, the inner skin layer 140 and the core material 130 are compressed while melting, forming the thin-walled portion 170, as shown in FIG. 3(c). Next, as shown in FIG. 3(d), the thin-walled portion 170 is bent upward and brought into close contact with the end surface 131 of the core material 130. The end surface 131 is heated and melted by the heating plate 720, and the thin-walled portion 170 is also heated and melted by the heating plate 720, so that the two are firmly welded in a close contact state. Then, as shown in FIG. 3(e), the tip 171 of the thin-walled portion 170 protruding from the surface of the inner skin layer 140 is cut off, completing the end surface treatment of the end edge 120. As shown in FIG. 3(f), when the end surface treatment is completed, the internal structure exposed from the end edge 120 of the hollow structure plate 100 is sealed by the thin-walled portion 170. And, by applying the end surface treatment to the end edges 110 and 120 of the hollow structure plate 100, it is possible to effectively prevent a person's fingers from being injured even if they touch the side panel when carrying the droplet infection prevention screen.

When the droplet infection prevention screen is used upright, the sharp tips of the corners of the hollow structure board 100 may hit people or objects and become a hindrance, so it is preferable to apply edge treatment to the corners 101 as well, as shown in Figure 4. Figure 4(a) is a plan view of the hollow structure board 100 showing how the corners 101 are being edge treated, Figures 4(b), (c), (e), and (f) are side views of the vicinity of the corners 101 of the hollow structure board 100 showing how the edge treatment is being applied (side views seen from the arrow C shown in Figure 4(a)), and Figure 4(d) is a plan view of the vicinity of the corners 101 showing how the corners 101 are being edge treated.

As shown in FIG. 4(a), in order to perform end surface processing on the corner portion 101 of the hollow structure plate 100, a heating plate 730 having a width capable of diagonally crossing the corner portion 101 is pressed against the corner portion 101 from above. Specifically, as shown in FIG. 4(b), a flat pressing surface 731 of the heating plate 730 is pressed against the inner skin layer 140 of the hollow structure plate 100 from above. This pressing surface 731 is heated to a temperature capable of melting the inner skin layer 140 and the core material 130, so that when the heating plate 730 presses the inner skin layer 140 downward, the inner skin layer 140 and the core material 130 are compressed while melting as shown in FIG. 4(c) and FIG. 4(d), and become the thin-walled portion 180. Next, as shown in FIG. 4(e), the thin-walled portion 180 is bent upward to be in close contact with the end surface 131 of the core material 130. The end surface 131 is heated and melted by the heating plate 730, and the thin-walled portion 180 is also heated and melted by the heating plate 730, so that the two are firmly welded in a state of close contact. Then, as shown in FIG. 4(f), the tip 181 of the thin-walled portion 180 protruding from the surface of the inner skin layer 140 is cut off, and the end surface processing of the corner portion 101 is completed. Then, as shown in FIG. 5, the sharp portion at the tip of the corner portion 101 disappears. In addition, the amount of resin in the corner portion 101 (where the thin-walled portion 160 and the thin-walled portion 180 overlap, and where the thin-walled portion 170 and the thin-walled portion 180 overlap) is increased by the end surface processing by the heating plate 710 described in FIG. 2, the end surface processing by the heating plate 720 described in FIG. 3, and the end surface processing by the heating plate 730 described in FIG. 4, and the strength is increased because the resin penetrates into the inside of the core material 130. And because the strength of the corners 101, which are most susceptible to damage during use or transportation, has been increased, the droplet infection prevention screen can be effectively prevented from being damaged. Also, because there is a large amount of resin in the corners, the thin-walled portion 180 becomes wider when pressed by the heating plate 730. Therefore, when the thin-walled portion 180 is folded back upward, it can cover part or all of the end surface 131 of the core material 130, and by cutting the top surface and three places on the left and right (in a U-shape), it can be sealed without exposing the end surface 131.

The tips of the thin-walled parts 160, 170, and 180 face the inner skin layer 140, which is the surface that is folded inward and hidden when the droplet infection prevention screen is folded as described below. This effectively prevents the tips of the thin-walled parts from scratching a person's fingers when the droplet infection prevention screen is held from the outside and carried. In addition, the end surface treatment is performed on the entire circumference of the end edges 110 and 120 of the hollow structure board 100, but this is not limited to this, and the end surface treatment may be performed only partially on the parts where the internal structure is exposed. In addition, the part that does not need to be subjected to the end surface treatment, such as the lower end side of the end edge 110 (the side placed on the installation stand, etc.), which is not a part that a person touches, may not need to be subjected to the end surface treatment partially. In addition, the end surface treatment may be performed only on the end edges 110 and 120 of the hollow structure board 100, and the end surface treatment of the corner part 101 may not be performed.

Next, as shown in FIG. 5, each groove is formed in the hollow structure plate 100 that has been subjected to edge processing. In FIG. 5(a), two hollow structure plates 100 are arranged side by side, and the right hollow structure plate 100 is the hollow structure plate 100 that has been subjected to edge processing as shown in FIG. 1 to FIG. 4. The left hollow structure plate 100 is processed in the same manner as the edge processing shown in FIG. 1 to FIG. 4, and has a structure that is symmetrical to the right hollow structure plate 100. The right hollow structure plate 100 constitutes the first side plate 103 described later, and the left hollow structure plate 100 constitutes the second side plate 104 described later. In addition, FIG. 5(a) is a plan view of each hollow structure plate 100 that has been subjected to edge processing, and FIG. 5(b) is a plan view showing the location where each groove is formed in each hollow structure plate 100.

Specifically, as shown in FIG. 5(b), in the right hollow structure plate 100, an inner first groove portion 200 (described later) is formed along a straight line D extending toward the opposing end edge 110. The inner first groove portion 200 divides the hollow structure plate 100 into an end plate 102 and a first side plate 103. Furthermore, in the first side plate 103, an outer first groove portion 300 (described later) is formed at a position adjacent to the straight line D along a straight line E extending toward the opposing end edge 110. Furthermore, in the left hollow structure plate 100, an inner second groove portion 400 (described later) is formed along a straight line F extending toward the opposing end edge 110. The inner second groove portion 400 divides the hollow structure plate 100 into an end plate 102 and a second side plate 104. Furthermore, the second side panel 104 has a second outer groove 500 (described later) formed at a position adjacent to the straight line F along a straight line G that extends toward the opposing end edge 110.

Next, a method for forming the inner first groove portion 200 and the outer first groove portion 300 will be described with reference to FIG. 6. Note that FIG. 6(a) to (c) are enlarged front views of the inner first groove portion 200 and the outer first groove portion 300 of the hollow structure plate 100 (front views seen from the arrow H shown in FIG. 5(b)).

As shown in FIG. 6(a), the heating plate 750 is pressed from above the inner skin layer 140 of the hollow structure plate 100. Since the heating plate 750 extends along the straight line E, the outer first groove portion 300 can be formed at once so as to cross the opposing end edge 110. The heating plate 750 is configured in an approximately V-shape with a flat surface 751 at the tip and inclined surfaces 752 on both sides. The flat surface 751 and the inclined surfaces 752 of the heating plate 750 are heated to a temperature at which the inner skin layer 140 and the core material 130 inside can be melted, so that the heating plate 750 presses the inner skin layer 140 downward, and as shown in FIG. 6(b), the inner skin layer 140 and the core material 130 are compressed while melting, and the outer first groove portion 300 is formed. The outer first groove portion 300 is formed in a straight line along the straight line E, and the vertical cross section perpendicular to the longitudinal direction is approximately V-shaped. The outer first groove portion 300 has a flat bottom surface 310 and side surfaces 320 inclined on both sides of the bottom surface 310. The surfaces of the bottom surface 310 and the side surfaces 320 are smooth because the inner skin layer 140 is melted. The periphery of the bottom surface 310 is a thin-walled portion 330 that is locally thinned by being compressed by the heating plate 750, so the outer first groove portion 300 can be folded inward starting from this thin-walled portion 330. At that time, either the inner corner portion 301 or the outer corner portion 302 of the thin-walled portion 330 may be folded starting from the inner corner portion 301 on the side closer to the main body plate 607, which is a long plate. In addition, when the first side plate 103 is a short plate that is shorter than the main body plate 607 described later, the first side plate 103, which is a short plate, is grasped and folded, so that the inner corner portion 301 on the side closer to the main body plate 607, which is a long plate, is folded starting from the inner corner portion 301. When the inner skin layer 140 is compressed by the heating plate 750, some of the molten resin of the inner skin layer 140 overflows onto the end 321 of the side surface 320, forming a protrusion 322.

Next, as shown in FIG. 6(a), a heating plate 740 is pressed from above the inner skin layer 140 of the hollow structure plate 100. Since this heating plate 740 extends along a straight line D, the inner first groove portion 200 can be formed at once so as to cross the opposing end edge 110. The heating plate 740 is configured in an approximately V-shape with a flat surface 741 at the tip and inclined surfaces 742 on both sides. The flat surface 741 and the inclined surfaces 742 of the heating plate 740 are heated to a temperature at which the inner skin layer 140 and the core material 130 inside can be melted, so that the heating plate 740 presses the inner skin layer 140 downward, and as shown in FIG. 6(b), the inner skin layer 140 and the core material 130 are compressed while melting, forming the inner first groove portion 200. The inner first groove portion 200 is formed in a straight line along the straight line D, and the vertical cross section perpendicular to the longitudinal direction is approximately V-shaped. The inner first groove portion 200 has a flat bottom surface 210 and side surfaces 220 that are inclined on both sides of the bottom surface 210. The surfaces of the bottom surface 210 and the side surfaces 220 are smooth because the inner skin layer 140 has melted. The periphery of the bottom surface 210 is compressed by the heating plate 740 to form a thin-walled portion 230 that is locally thin, so that the inner first groove portion 200 can be folded inward from this thin-walled portion 230 as a starting point. When the inner skin layer 140 is compressed by the heating plate 740, part of the resin of the molten inner skin layer 140 overflows onto the end portion 221 of the side surface 220, forming a protrusion 222.

In addition, the heating plate 740 and the heating plate 750 are adjacent to each other with a predetermined interval (for example, the thickness of the hollow structure plate 100), so that a first support portion 260 is formed between the inner first groove portion 200 and the outer first groove portion 300. This first support portion 260 is formed in a straight line toward the opposing end side 110, and the vertical section perpendicular to the longitudinal direction is approximately trapezoidal. The inner width (width between the end portion 221 and the end portion 321) of the first support portion 260 is a predetermined width (for example, wider than the thickness of the hollow structure plate 100). In addition, the width L1 of the flat surface 751 of the heating plate 750 is wider than the width L2 of the flat surface 741 of the heating plate 740. Therefore, the width L3 of the thin-walled portion 330 formed by the flat surface 751 is wider than the width L4 of the thin-walled portion 230 formed by the flat surface 741.

Next, as shown in FIG. 6(c), the inner first groove portion 200 is folded inward. Since the side surface 220 of the inner first groove portion 200 is heated and melted by the heating plate 740, the side surfaces 220 are firmly welded together in a folded and intimate contact state, and the inner first groove portion 200 is fixed in a folded and approximately L-shaped state. The first support portion 260 adjacent to the inner first groove portion 200 is also fixed to the end plate 102. This first support portion 260 extends toward the opposing end edge 110, and as described later, serves as a portion that supports the first side plate 103 so that the first side plate 103 can be opened and closed relative to the end plate 102. In addition, the protrusions 222 of the ends 221 of the side surfaces 220 are also welded together, increasing the welding area and allowing the inner first groove portion 200 to be welded more firmly. Additionally, the inner first groove portion 200 is fixed by heating and welding, but this is not limited to this and any fixing method may be used, such as fixing using an adhesive or the like.

The substantially V-shape of the inner first groove 200 includes a shape recessed inward by the inclined side surfaces 220 on both sides, regardless of whether it has a bottom surface 210, and the substantially V-shape of the outer first groove 300 includes a shape recessed inward by the inclined side surfaces 320 on both sides, regardless of whether it has a bottom surface 310. The inner first groove 200 and the outer first groove 300 are substantially V-shaped, but are not limited to this, and the inner first groove 200 and the outer first groove 300 may be any shape, such as a substantially U-shape or a substantially trapezoidal shape, as long as a part of the groove is thin and can be bent inward. The first support 260 is not limited to a substantially trapezoidal shape, and may be any shape. In addition, the substantially trapezoidal shape of the first support portion 260 is not limited to a trapezoidal shape surrounded by one side surface 220 and the other side surface 320 having the same inclination angle and equal interior angle, and the outer surface and the inner surface of the hollow structure plate 100, and most of the first support portion 260 includes a shape surrounded by four surfaces, namely, one side surface 220 and the other side surface 320 having different inclination angles, and the inner surface and the outer surface of the hollow structure plate 100. In addition, the inner angle α of the bent inner first groove portion 200 is 90 degrees or more, so that it is easy to wipe off dirt, etc. In addition, in the substantially V-shaped state before bending, the inner first groove portion 200 has an angle of 90 degrees or more, but is not limited to this, and the angle of the groove may be small (for example, 90 degrees or less). Then, when the inner first groove portion 200 is bent, the inner angle α becomes large, so that it is easier to wipe off dirt, etc. In addition, the substantially L-shaped bent inner first groove portion 200 is not limited to a bent inner angle α, but includes a state in which the inner first groove portion 200 is bent at any angle so as to rise up from the end plate 102. In addition, although the heating plate 740 and the heating plate 750 are mounted in the same device and processed, this is not limited thereto, and the heating plate 740 and the heating plate 750 may be mounted in different devices and processed separately in each device.

Next, a method for forming the inner second groove portion 400 and the outer second groove portion 500 will be described with reference to FIG. 7. Note that FIG. 7(a) to (c) are enlarged front views of the inner second groove portion 400 and the outer second groove portion 500 of the hollow structure plate 100 (front views seen from the arrow I shown in FIG. 5(b)).

As shown in FIG. 7(a), the heating plate 770 is pressed from above the inner skin layer 140 of the hollow structure plate 100. Since the heating plate 770 extends along the straight line G, the outer second groove portion 500 can be formed at once so as to cross the opposing end edge 110. The heating plate 770 is configured in an approximately V-shape with a flat surface 771 at the tip and inclined surfaces 772 on both sides. The flat surface 771 and the inclined surfaces 772 of the heating plate 770 are heated to a temperature at which the inner skin layer 140 and the core material 130 inside can be melted, so that the heating plate 770 presses the inner skin layer 140 downward, and as shown in FIG. 7(b), the inner skin layer 140 and the core material 130 are compressed while melting, and the outer second groove portion 500 is formed. The outer second groove portion 500 is formed in a straight line along the straight line G, and the vertical cross section perpendicular to the longitudinal direction is approximately V-shaped. The outer second groove portion 500 has a flat bottom surface 510 and side surfaces 520 inclined on both sides of the bottom surface 510. The surfaces of the bottom surface 510 and the side surfaces 520 are smooth surfaces due to the melting of the inner skin layer 140. The periphery of the bottom surface 510 is a thin-walled portion 530 in which the plate thickness is locally thinned by being compressed by the heating plate 770, so that the outer second groove portion 500 can be folded inward starting from this thin-walled portion 530. At that time, either the inner corner portion 501 or the outer corner portion 502 of the thin-walled portion 530 may be folded starting from the inner corner portion 501 on the side closer to the main plate 607, which is a long plate. In addition, when the second side plate 104 is a short plate shorter than the main plate 607 described later, the second side plate 104, which is a short plate, is grasped and folded, so that the inner corner portion 501 on the side closer to the main plate 607, which is a long plate, is folded starting from the inner corner portion 501. When the inner skin layer 140 is compressed by the heating plate 750, some of the molten resin of the inner skin layer 140 overflows onto the end 521 of the side surface 520, forming a protrusion 522.

Next, as shown in FIG. 7(a), a heating plate 760 is pressed against the inner skin layer 140 of the hollow structure plate 100 from above. This heating plate 760 extends along a straight line F, so that the inner second groove portion 400 can be formed at once so as to cross the opposing end edge 110. The heating plate 760 is configured in an approximately V-shape with a flat surface 761 at the tip and inclined surfaces 762 on both sides. The flat surface 761 and the inclined surfaces 762 of the heating plate 760 are heated to a temperature at which the inner skin layer 140 and the core material 130 inside can be melted, so that the heating plate 760 presses the inner skin layer 140 downward, and as shown in FIG. 7(b), the inner skin layer 140 and the core material 130 are compressed while melting, and the inner second groove portion 400 is formed. The inner second groove portion 400 is formed in a straight line along the straight line F, and the vertical cross section perpendicular to the longitudinal direction is approximately V-shaped. The inner second groove portion 400 has a flat bottom surface 410 and side surfaces 420 that are inclined on both sides of the bottom surface 410. The surfaces of the bottom surface 410 and the side surfaces 420 are smooth because the inner skin layer 140 is melted. In addition, the periphery of the bottom surface 410 is a thin-walled portion 430 that is locally thinned by being compressed by the heating plate 760, so that the inner second groove portion 400 can be folded inward starting from this thin-walled portion 430. When the inner skin layer 140 is compressed by the heating plate 760, part of the melted resin of the inner skin layer 140 overflows onto the end portion 421 of the side surface 420, forming a protrusion 422.

In addition, since the heating plates 760 and 770 are adjacent to each other with a predetermined interval (for example, the thickness of the hollow structure plate 100), a second support portion 460 is formed between the inner second groove portion 400 and the outer second groove portion 500. This second support portion 460 is formed in a straight line toward the opposing end side 110, and the vertical section intersecting at a right angle to the longitudinal direction is approximately trapezoidal. The inner width (width between the end portion 421 and the end portion 521) of the second support portion 460 is a predetermined width (for example, wider than the plate thickness of the hollow structure plate 100). In addition, the width L5 of the flat surface 771 of the heating plate 770 is wider than the width L6 of the flat surface 761 of the heating plate 760. Therefore, the width L7 of the thin-walled portion 530 formed by the flat surface 771 is wider than the width L8 of the thin-walled portion 430 formed by the flat surface 761.

Next, as shown in FIG. 7(c), the inner second groove portion 400 is folded inward. Since the side surfaces 420 of the inner second groove portion 400 are heated and melted by the heating plate 760, the side surfaces 420 are firmly welded together in a folded and intimate contact state, and the inner second groove portion 400 is fixed in a folded and approximately L-shaped state. The second support portion 460 adjacent to the inner second groove portion 400 is also fixed to the end plate 102. This second support portion 460 extends toward the opposing end edge 110, and as described later, serves as a portion that supports the second side plate 104 so that the second side plate 104 can be opened and closed relative to the end plate 102. In addition, the protrusions 422 of the ends 421 of the side surfaces 420 are also welded together, increasing the welding area and making it possible to weld the inner second groove portion 400 more firmly. Additionally, the inner second groove portion 400 is fixed by heating and welding, but this is not limited to this and any fixing method may be used, such as fixing with an adhesive or the like.

The substantially V-shape of the inner second groove 400 includes a shape recessed inward by the inclined side surfaces 420 on both sides, regardless of whether or not it has a bottom surface 410, and the substantially V-shape of the outer second groove 500 includes a shape recessed inward by the inclined side surfaces 520 on both sides, regardless of whether or not it has a bottom surface 510. The inner second groove 400 and the outer second groove 500 are substantially V-shaped, but are not limited to this, and the inner second groove 400 and the outer second groove 500 may be any shape, such as a substantially U-shape or a substantially trapezoidal shape, as long as a part of them is thin-walled and can be bent inward. The second support 460 is not limited to a substantially trapezoidal shape, and may be any shape. In addition, the substantially trapezoidal shape of the second support portion 460 is not limited to a trapezoidal shape surrounded by one side surface 420 and the other side surface 520 having the same inclination angle and equal interior angle, and the outer surface and the inner surface of the hollow structure plate 100, and most of the second support portion 460 includes a shape surrounded by four surfaces, namely, one side surface 420 and the other side surface 520 having different inclination angles, and the inner surface and the outer surface of the hollow structure plate 100. In addition, the inner angle β of the bent inner second groove portion 400 is 90 degrees or more, so that it is easy to wipe off dirt, etc. In addition, in the substantially V-shaped state before bending, the inner second groove portion 400 has an angle of 90 degrees or more, but is not limited to this, and the angle of the groove may be small (for example, 90 degrees or less). Then, when the inner second groove portion 400 is bent, the inner angle β becomes large, so that it is easier to wipe off dirt, etc. In addition, the substantially L-shaped inner second groove 400 is not limited to being bent at an inner angle β, but includes a state in which the inner second groove 400 is bent at any angle so as to rise up from the end plate 102. In addition, although the heating plates 760 and 770 are mounted in the same device and processed, this is not limited thereto, and the heating plates 760 and 770 may be mounted in different devices and processed separately in each device.

Then, after forming each groove portion as shown in Figures 6 and 7, a transparent plate 600 is attached to the end plate 102 adjacent to the first side plate 103 and the end plate 102 adjacent to the second side plate 104, as shown in Figures 8 to 10, to complete the droplet infection prevention partition 700. 8(a) is an overall perspective view of the droplet infection prevention screen 700, FIG. 8(b) is an enlarged perspective view of the vicinity of the attachment point of the second side panel 104 and the transparent panel 600, FIG. 8(c) is an enlarged perspective view of the vicinity of the attachment point of the first side panel 103 and the transparent panel 600, FIG. 9(a) is a rear view of the droplet infection prevention screen 700, FIG. 9(b) is a plan view of the droplet infection prevention screen 700, FIG. 10(a) is an overall perspective view of the droplet infection prevention screen 700 as seen from the rear side, FIG. 10(b) is an enlarged perspective view of the periphery of the tube portion 670 as seen from the rear side on the outside, FIG. 10(c) is an enlarged perspective view of the periphery of the tube portion 670 as seen from the front side on the inside, and FIG. 10(d) is a cross-sectional view taken along the line J-J.

8 and 9, one end 605 of the approximately rectangular transparent plate 600 is connected to the end plate 102 that is continuous with the first side plate 103, and the other end 605 is connected to the end plate 102 that is continuous with the second side plate 104. The transparent plate 600 and the end plate 102 connected at the ends 605 on both sides form the main plate 607. The end 605 and the end plate 102 are connected by attaching the inner surface of the end 605 to the inner surface of the end plate 102 with double-sided tape, but this is not limited to this, and any method can be used, such as attaching the end 605 to the end plate 102 with an adhesive. The transparent plate 600 is made of vinyl chloride resin and is transparent or semi-transparent to ensure visibility. The transparent plate 600 is made of vinyl chloride resin, but this is not limited to this, and it may be made of any material as long as it is transparent or semi-transparent to ensure visibility.

8 and 9, the first side panel 103 can be folded toward the inside of the transparent panel 600 of the main panel 607 by bending the outer first groove 300 inward. Since the inner first groove 200 is fixed in an approximately L-shape in the folded state, the first side panel 103 can be easily opened and closed toward the main panel 607 starting from the outer first groove 300 adjacent to the inner first groove 200. Furthermore, the second side panel 104 can be folded toward the inside of the transparent panel 600 of the main panel 607 by bending the outer second groove 500 inward. Since the inner second groove 400 is fixed in an approximately L-shape in the folded state, the second side panel 104 can be easily opened and closed toward the main panel 607 starting from the outer second groove 500 adjacent to the inner second groove 400.

9 and 10, the transparent plate 600 is provided with two circular through holes 610 penetrating from the inside to the outside, and a tube portion 670 is joined to each through hole 610. Specifically, the tube portion 670 is made of polyvinyl chloride resin and formed into a cylindrical shape, and as shown in Figs. 10(c) and (d), the inner end 671 of the tube portion 670 is disposed in the through hole 610, and the end 671 of the tube portion 670 is flush with the inner surface 601 of the transparent plate 600 of the main body plate 607. Furthermore, polyvinyl chloride resin is poured as a bonding agent 613 into the boundary portion 612 between the through hole 610 and the tube portion 670 to bond the tube portion 670 to the through hole 610 and fix the tube portion 670. In order to make it easier to insert the tube portion 670 into the through hole 610, the diameter of the outer circumference of the tube portion 670 is made a few millimeters smaller than the diameter of the through hole 610, and a small gap 611 is formed between the end 671 of the tube portion 670 and the through hole 610 at a part or the entire circumference. (In FIG. 10(d), the tube portion 670 is in contact with the edge of the through hole 610 at the lower side due to its own weight, but there is a small gap 611 at the upper side.) Then, the bonding agent 613 is poured into this gap 611 to fill it. This increases the bonding area between the through hole 610 and the tube portion 670, improving the bonding strength. In addition, the outer end 672 of the tube portion 670 protrudes toward the outside of the transparent plate 600 of the main body plate 607.

In addition, both the part of the main plate 607 to which the tube portion 670 is attached (the transparent plate 600 in FIG. 10) and the tube portion 670 are made of the same resin, polyvinyl chloride resin, and the adhesive 613 poured into the boundary portion 612 between the through hole 610 and the tube portion 670 also uses the same polyvinyl chloride resin. Therefore, the adhesion between the tube portion 670 and the main plate 607 is good, and the tube portion 670 can be firmly fixed. Furthermore, because the resin is poured into the boundary portion 612 between the tube portion 670 and the through hole 610, no gaps are formed at the boundary portion 612, which prevents droplet infection from the patient, as described below.

The through hole 610 is provided in the transparent plate 600 of the main plate 607, but is not limited thereto. The through hole 610 may be provided in any location as long as it is a part of the main plate 607. For example, the main plate 607 may have a transparent plate 600 on the upper half side and a colored plate material on the lower half side. In that case, the through hole 610 is provided in the colored plate material on the lower half side and the tube part 670 is joined to it. In addition, the end plates 102 on both sides of the main plate 607 are made of hollow structure plates 100, and the majority of the center is made of transparent plate 600, but is not limited thereto. As long as a transparent plate 600 for visually checking the patient is provided in a part of the main plate 607, the majority of the main plate 607 may be made of hollow structure plates 100 or may be made of any colored plate material.

As shown in Figs. 10(c) and (d), the end 671 of the tube portion 670 is flush with the inner surface 601 of the transparent plate 600 of the main body plate 607, but this is not limited thereto, and the end 671 of the tube portion 670 may protrude from the surface 601 of the transparent plate 600 to form a step. The tube portion 670 has a cylindrical shape with a circular cross section, but this is not limited thereto, and may have any shape as long as it allows the arm or hand of a doctor or part of a diagnostic instrument to pass through it to examine a patient, as described below. The tube portion 670 is made of polyvinyl chloride resin, but this is not limited thereto, and it may be made of any material.

In addition, the tube portion 670 protrudes toward the outside of the main body plate 607 on the opposite side to the inner surface 601 of the main body plate 607 on which the first side plate 103 and the second side plate 104 are folded, but this is not limited thereto and may protrude toward the inside of the main body plate 607. However, by having the tube portion 670 protrude toward the outside of the main body plate 607, when the first side plate 103 and the second side plate 104 are folded, the entire droplet infection prevention partition 700 can be folded small and flat without interfering with the tube portion 670. Furthermore, as described below, in order to examine a patient in the space partitioned by the first side plate 103 and the second side plate 104, if the tube portion 670 protrudes toward the inside of the main body plate 607, there is a risk that droplets from the patient will adhere to the tube portion 670. In addition, since the doctor examines the patient through the tube portion 670, it is desirable to avoid droplets adhering to the tube portion 670 as much as possible from the viewpoint of infection prevention. Therefore, by having the tube portion 670 protrude outward from the opposite side of the inner surface 601 of the main body plate 607, it is possible to prevent droplets and the like from adhering to the tube portion 670. Also, even if the first side plate 103 and the second side plate 104, which may have droplets from the patient attached thereto, are folded inside the main body plate 607, they do not come into contact with the tube portion 670, making it hygienic. Furthermore, the first side plate 103, the second side plate 104, and the inside of the main body plate 607 are almost flat surfaces, making it easy to wipe off droplets from the patient.

Next, Fig. 11 shows the droplet infection prevention screen 700 in a folded state. Fig. 11(a) is an overall perspective view of the droplet infection prevention screen 700 in a folded state, Fig. 11(b) is an enlarged perspective view of the second support part 460 and its periphery of the droplet infection prevention screen 700 in a folded state, as viewed from the bottom side, and Fig. 11(c) is an enlarged perspective view of the first support part 260 and its periphery of the droplet infection prevention screen 700 in a folded state, as viewed from the bottom side.

As shown in FIG. 11, by folding the first side panel 103 and the second side panel 104 toward the inside of the transparent panel 600 of the main panel 607, the entire droplet infection prevention screen 700 can be made small and flat, making it convenient to carry and store without taking up much space. Furthermore, because the droplet infection prevention screen 700 has a portion made up of the hollow structure panel 100, it is light in weight and easy to carry.

In the droplet infection prevention screen 700, the inner first groove 200 is fixed in an approximately L-shape, but this is not limited to this. For example, the inner first groove 200 may not be fixed, the inner first groove 200 may be left in a foldable state, and one of the outer first grooves 300 may be folded inward and fixed in an approximately L-shape. Also, both the inner first groove 200 and the outer first groove 300 may be left unfixed and left in a foldable state. In either case, since there is at least one or more foldable points, the first side panel 103 can be easily folded and the droplet infection prevention screen 700 can be made small and flat, making it convenient to carry and store without being bulky.

In addition, in the droplet infection prevention partition 700, the inner second groove portion 400 is fixed in an approximately L-shape, but this is not limited to this. For example, the inner second groove portion 400 may not be fixed, the inner second groove portion 400 may be left in a foldable state, and one of the outer second groove portions 500 may be folded inward and fixed in an approximately L-shape. Also, both the inner second groove portion 400 and the outer second groove portion 500 may be left unfixed and left in a foldable state. In either case, since there is at least one or more foldable points, the second side panel 104 can be easily folded and the droplet infection prevention partition 700 can be made small and flat, making it convenient to carry and store without being bulky.

In addition, the droplet infection prevention screen 700 has two folding points, the inner first groove 200 and the outer first groove 300, adjacent to the first side panel 103, and two folding points, the inner second groove 400 and the outer second groove 500, adjacent to the second side panel 104. This makes it easy to fold the first side panel 103 and the second side panel 104, and allows the entire droplet infection prevention screen 700 to be folded compactly.

In addition, the droplet infection prevention partition 700 has two folding points, an inner first groove portion 200 and an outer first groove portion 300, adjacent to the first side panel 103, and two folding points, an inner second groove portion 400 and an outer second groove portion 500, adjacent to the second side panel 104, but is not limited to this, and may have one folding point of the inner first groove portion 200 adjacent to the first side panel 103, and one folding point of the inner second groove portion 400 adjacent to the second side panel 104. If the first inner groove portion 200 and the second inner groove portion 400 are not fixed but left in a foldable state, the first side panel 103 and the second side panel 104 can be opened and closed, and the droplet infection prevention partition 700 can be used to divide a space by making it roughly U-shaped. Also, the first side panel 103 and the second side panel 104 can be folded to make the droplet infection prevention partition 700 smaller.

As shown in FIG. 6(b), the width L3 of the thin portion 330 of the outer first groove portion 300 is wider than the width L4 of the thin portion 230 of the inner first groove portion 200. Therefore, as shown in FIG. 11(c), when the outer first groove portion 300 is folded to fold the first side panel 103, the resilience of the outer first groove portion 300 when folded can be suppressed. In addition, when the inner first groove portion 200 is fixed in a folded state, the resilience of the inner first groove portion 200 when folded is suppressed by fixing it, so there is no problem even if the width L4 of the thin portion 230 of the inner first groove portion 200 is narrowed.

11(c), the edge 110 of the first side panel 103 is bent at an approximately right angle by end surface treatment, so that the corner 162 at the boundary between the edge 110 and the thin portion 160 is also approximately right-angled and has a small radius of curvature. Therefore, when the droplet infection prevention screen 700 is used upright, the mounting area of the lower end of the droplet infection prevention screen 700 on an installation stand or the like can be secured. On the other hand, the thin portion 330 of the outer first groove portion 300 is wide and the bottom surface 310 is a flat surface, so that the outer corner 331 of the thin portion 330 when the outer first groove portion 300 is bent is gently curved and has a large radius of curvature. In this way, the radius of curvature of the outer corner 331 of the outer first groove 300 is larger and gentler than the corner 162 of the first side panel 103 where the end face has been treated, so when carrying the droplet infection prevention partition 700, even if you hold the area near the bent part, the outer first groove 300, from the outside with your hand, it will not hurt.

As shown in FIG. 7(b), the width L7 of the thin portion 530 of the outer second groove portion 500 is wider than the width L8 of the thin portion 430 of the inner second groove portion 400. Therefore, as shown in FIG. 11(b), when the outer second groove portion 500 is folded to fold the second side panel 104, the resilience of the outer second groove portion 500 when folded can be suppressed. In addition, when the inner second groove portion 400 is fixed in a folded state, the resilience of the inner second groove portion 400 when folded is suppressed by fixing it, so there is no problem even if the width L8 of the thin portion 430 of the inner second groove portion 400 is narrowed.

11(b), the edge 110 of the second side panel 104 is bent at an approximately right angle by end surface treatment, so that the corner 162 at the boundary between the edge 110 and the thin portion 160 is also approximately right-angled and has a small radius of curvature. Therefore, when the droplet infection prevention screen 700 is used upright, the mounting area of the lower end of the droplet infection prevention screen 700 on an installation stand or the like can be secured. On the other hand, the thin portion 530 of the outer second groove 500 is wide and the bottom surface 510 is a flat surface, so that the outer corner 531 of the thin portion 530 when the outer second groove 500 is bent is gently curved and has a large radius of curvature. In this way, the radius of curvature of the outer corner 531 of the outer second groove 500 is larger and gentler than the corner 162 of the second side panel 104 where the end face has been treated, so when carrying the droplet infection prevention partition 700, it is not painful to hold the area near the outer second groove 500, which is the bent part, from the outside with your hand.

11, the droplet infection prevention partition 700 has a substantially trapezoidal first support portion 260 between the end plate 102 and the first side plate 103 of the main plate 607, so that a space can be provided between the first side plate 103 and the transparent plate 600 of the main plate 607. Similarly, a substantially trapezoidal second support portion 460 is provided between the end plate 102 and the second side plate 104 of the main plate 607, so that a space can be provided between the second side plate 104 and the transparent plate 600 of the main plate 607. If the first side plate 103 or the second side plate 104 is wider than that shown in FIG. 11, the folded first side plate 103 and the second side plate 104 will overlap each other, but the previously folded side plate can be folded and stored in the space created by the first support portion 260 or the second support portion 460. The other side panel folded later can be overlapped so as to be in close contact with the other side panel folded earlier, so that each side panel can be folded without being bulky. As shown in FIG. 11, if the width of the first side panel 103 and the second side panel 104 is short and the folded first side panel 103 and the second side panel 104 do not overlap each other, the first support part 260 and the second support part 460 may be made substantially triangular, so that the space between the first side panel 103 and the transparent panel 600 of the main panel 607 and the space between the second side panel 104 and the transparent panel 600 of the main panel 607 may be reduced or eliminated. In that case, the folded first side panel 103 and the second side panel 104 can be folded so as to be in close contact with the transparent panel 600 of the main panel 607, so that each side panel can be folded without being bulky.

Next, Figures 12 to 14 show how to use the droplet infection prevention screen 700. 12(a) is a perspective view from the front side of the droplet infection prevention screen 700 installed on the installation stand 800, FIG. 12(b) is a perspective view from the back side of the droplet infection prevention screen 700 installed on the installation stand 800, FIGS. 13(a) and (b) are enlarged perspective views from the back side showing the attachment of a glove 900 to the tube portion 670 of the droplet infection prevention screen 700, FIG. 13(c) is a perspective view from the back side of the droplet infection prevention screen 700 installed on the installation stand 800 with the glove 900 attached, FIG. 14(a) is a perspective view from the back side showing the attachment of a lid 780 to the droplet infection prevention screen 700, and FIG. 14(b) is a side view showing a doctor or the like diagnosing a patient using the droplet infection prevention screen 700.

A user of the droplet infection prevention screen 700 carries the folded droplet infection prevention screen 700 to an installation stand 800 placed in a well-ventilated place such as outdoors (for example, inside a tent installed outdoors), and installs it on the flat top plate 810 of the installation stand 800 as shown in FIG. 12. When installing it on the top plate 810, the first side plate 103 and the second side plate 104 are opened, and the droplet infection prevention screen 700 is made into an approximately U-shape to divide the space above the top plate 810. In addition, the first side plate 103 and the second side plate 104 are fixed in an open state on the top plate 810 by a fixing device 811 so that the first side plate 103 and the second side plate 104 do not close inadvertently. For the fixing device 811, an existing fixing member such as Velcro (registered trademark) or a suction cup can be used as long as it can fix the first side plate 103 and the second side plate 104 so that they do not close. In addition, the bottom end of the main body plate 607 of the droplet infection prevention partition 700, the bottom end of the first side panel 103, and the bottom end of the second side panel 104 are flat surfaces, and all bottom ends of the droplet infection prevention partition 700 are flush, so no gaps are created between the partition and the flat top plate 810 of the installation stand 800, effectively preventing droplet infection.

In addition, the installation stand 800 has a roughly cubic shape with a top plate 810, but is not limited to this and may have any shape as long as the droplet infection prevention partition 700 can be installed on it. The droplet infection prevention partition 700 can be used both indoors and outdoors, but it is preferable to use it outdoors in a well-ventilated area to prevent secondary infection indoors. The droplet infection prevention partition 700 is light in weight and can be made small and flat, so it can be easily carried out and used anywhere, even outdoors.

Next, as shown in FIG. 13(a), the cuff 910 of the glove 900 (glove) is inserted from the inner surface 601 of the transparent plate 600 into the inside of the tube portion 670, and the cuff 910 of the glove 900 is pulled out from the tube portion 670 to the outside. Then, the cuff 910 pulled out to the outside is turned inside out and fitted so as to cover the outer edge of the end 672 of the tube portion 670. Note that the method of attaching the glove 900 to the tube portion 670 is not limited to this, and any method can be adopted. For example, as shown in FIG. 13(b), first, the cuff 910 of the glove 900 is fitted into the outer edge of the end 672 of the tube portion 670. Then, as shown in FIG. 13(a), the tip 920 of the fingertip of the glove 900 is passed through the inside of the tube portion 670 and pulled out to the inner surface 601 side of the transparent plate 600. As a result, the glove 900 turns inside out, and the outer surface 901 of the glove 900 in the state shown in FIG. 13(b) turns inside out onto the inner surface of the glove 900 in the state shown in FIG. 13(a). Conversely, the inner surface 902 of the glove 900 in the state shown in FIG. 13(b) turns inside out onto the outer surface of the glove 900 in the state shown in FIG. 13(b).

13(c), the glove 900 attached to the tube portion 670 protruding outward is placed in a space 820 surrounded by the transparent plate 600, the first side plate 103, and the second side plate 104 of the main body plate 607 through the inside of the tube portion 670. This space 820 becomes the space surrounding the patient P1, as described below. Note that in FIG. 13, the tube portion 670 protrudes outward from the transparent plate 600, and the glove 900 is attached to the tube portion 670 protruding outward, but this is not limited thereto, and the tube portion 670 may protrude both inside and outside the transparent plate 600 so that the glove 900 can be attached from either the inside or outside of the transparent plate 600. Furthermore, if the tube portion 670 protrudes from both the inside and outside of the transparent plate 600, the tube portion 670 can be securely fixed by pouring adhesive 613 into the boundary portion 612 between the through hole 610 and the tube portion 670 from both the inside and outside of the transparent plate 600.

As shown in FIG. 14(a), a cover 780 is optionally attached to cover the upper part of the main plate 607 of the droplet infection prevention partition 700 in order to effectively prevent droplet infection from the patient P1. The cover 780 has a top plate 781, side edges 782 on both sides that bend downward from the top plate 781, and a side edge 783 on the rear side, and the side edges 782 are fixed to the first side plate 103 and the second side plate 104 by a fixing member 784 such as a hook-and-loop fastener. The side edges 782 are attached so as to cover the upper ends of the first side plate 103 and the second side plate 104, and the side edges 783 are attached so as to cover the upper end of the main plate 607, so that the upper part of the space 820 is covered without any gaps, effectively preventing droplet infection from the patient P1.

During an actual examination, as shown in FIG. 14(b), patient P1 suffering from an infectious disease is positioned on the side of space 820 surrounded by transparent plate 600, first side plate 103, and second side plate 104 of main plate 607, and doctor P2 is positioned on the opposite side, sandwiched between transparent plate 600 of main plate 607 of droplet infection prevention partition 700. Doctor P2 passes his/her hand through tube portion 670 protruding outward, and inserts his/her hand into glove 900 placed in space 820 through the inside of tube portion 670. Patient P1 leans forward slightly and brings his/her face closer to space 820, and doctor P2 examines patient P1 by touching him/her through glove 900 in space 820. Doctor P2 can see the condition of patient P1 through the transparent plate 600, so the examination is not hindered, and droplet infection from patient P1 can be prevented because a droplet infection prevention partition 700 is placed between doctor P2 and patient P1. In addition, by making the first side plate 103 or the second side plate 104, or both the first side plate 103 and the second side plate 104, which cover both sides of the space 820, colored, the face of patient P1 can be hidden from the surroundings, and the privacy of patient P1 can be protected.

In this way, the droplet infection prevention screen 700 of the present invention can divide a space, for example, in a roughly U-shape, using the first side panel 103 and the second side panel 104, so it can be easily installed anywhere and can easily provide an examination space that prevents droplet infection. In addition, the doctor P2 can see the condition of the patient P1 through the transparent panel 600, so there is no hindrance to the examination. Furthermore, the doctor P2 can examine the patient P1 by putting his/her hand through the tube portion 670, so the doctor P2 can smoothly put his/her hand through the screen 700 to examine the patient, without his/her hand getting caught in any part of the droplet infection prevention screen 700.

In addition, when the glove 900 is used during examination, the glove 900 attached to the tube portion 670 protruding outward can be placed inside the tube portion 670 and in the space 820 surrounded by the main plate 607, the first side plate 103, and the second side plate 104, so there is no gap between the patient P1 and the doctor P2, and droplet infection can be effectively prevented. In addition, since the glove 900 is attached through the inside of the tube portion 670, even if the doctor P2 puts his hand into the glove 900 through the tube portion 670 to examine the patient, the glove 900 is unlikely to come off. Furthermore, when the first side plate 103 and the second side plate 104 are folded, the glove 900 is covered and protected by the first side plate 103 and the second side plate 104, so it is unlikely to be damaged during storage, transportation, etc. When discarding the glove 900 after the examination, the doctor P2 can take out the glove 900 by pinching the inside of the glove 900 in the state shown in FIG. 14(b) and turning it inside out, and then passing the glove 900 through the inside of the tube portion 670. Therefore, the doctor P2 can take out and discard the glove 900 without touching the surface of the glove 900 (inner surface 902) that may be contaminated by droplets from the patient P1, which effectively prevents the doctor P2 from becoming infected.

13 and 14, the glove 900 attached to the tube portion 670 protruding outward is placed in the space 820 through the inside of the tube portion 670, but this is not limited thereto. The doctor P2 may put his hand in the space 820 through the inside of the tube portion 670 while wearing the glove 900 on his own hand. As shown in FIG. 10(d), the inner surface 601 of the transparent plate 600 and the end portion 671 of the tube portion 670 are flush with each other, so there is no protruding portion such as a step between the end portion 671 and the surface 601. Therefore, when using the glove 900 for examination, etc., the glove 900 can be prevented from being torn and damaged by a protruding portion such as a step. Also, when the glove 900 is pulled out from the space 820 through the tube portion 670 after the examination is finished and discarded, the glove 900 can be prevented from being torn and damaged by a protruding portion such as a step.

The droplet infection prevention screen of the present invention is not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of the rights.
