Description

The present invention relates to a medical pouch that receives liquid from the surgical field at the time of surgery, a medical drape including the medical pouch, and a single-use medical device set including the medical drape.

Conventionally, when medical procedures such as surgery are performed in an operating room, the body surface of a patient defined as an unclean area is covered with a medical drape, and the clean area is isolated from the unclean area. There is. The drape is provided with an opening for exposing the surgical field, which is the surgical target site of the patient, from the drape.

By the way, in craniotomy or knee joint surgery using an arthroscope, the surgery may be performed while continuously or intermittently applying physiological saline or the like to the surgical field. In the drape used for such surgery, a medical pouch that receives waste liquid such as saline and blood flowing down from the surgical field and sends it to a predetermined waste liquid tank etc. is attached near the opening for exposing the surgical field. Has been done.

For example, the drape of Patent Document 1 discloses a technique of providing a band-shaped frame along the upper edge of the bag at a portion on the front side of the running water bag that receives the waste liquid. In the drape, the frame body made of a metal bar or a plastic material is curved in a semicircular shape to widen the upper opening of the bag body in a semicircular shape, so that the waste liquid can easily flow into the running water bag.

Further, Patent Document 2 discloses a technique of providing a shape-retaining member at the lower part of each sheet member in a medical pouch in which two sheet members having substantially the same shape are stacked and the left and right edges are joined to form a seal portion.

The first sheet portion 11 and the second sheet portion 12 are preferably made of polyethylene, more preferably linear low density polyethylene (L-LDPE).

In the examples shown in FIGS. 3 and 4, the first sheet portion 11 and the second sheet portion 12 in the state before use are substantially pentagonal. The width of the first sheet portion 11 and the second sheet portion 12 in the left-right direction is substantially constant in the upper portion, and in the lower portion, the width increases from the upper side to the lower side in the drawing (that is, the upper liquid receiving port 21 is separated in the vertical direction). (According to) gradually decreases. The left and right side edge portions of the first sheet portion 11 are continuous with the left and right side edge portions of the second seat portion 12 from the upper end portion to the lower end portion. The upper edge portion of the first sheet portion 11 and the upper edge portion of the second sheet portion 12 are not continuous.

The shapes of the first sheet portion 11 and the second sheet portion 12 are not limited to a substantially pentagonal shape, and may be changed in various ways. Preferably, the width of at least the lower part of the first sheet portion 11 and the second sheet portion 12 in the left-right direction gradually decreases toward the lower side to form one apex at the lower end. In other words, the first sheet portion 11 and the second sheet portion 12 are preferably polygons such as a substantially triangle or a substantially pentagon in which one apex is located at the lower end. The angle α (that is, the internal angle) formed by the left and right side edges of the lower portions of the first sheet portion 11 and the second sheet portion 12 is preferably 60 ° or more and 120 ° or less, more preferably 80 ° or more and 100. ° or less.

As shown in FIG. 1, in the drape 3, the pouch 1 is fixed to the drape main body 31 by attaching the upper end portion of the first sheet portion 11 to the vicinity of the opening 310 of the drape main body 31. In the example shown in FIGS. 1 and 6, the outer surface of the upper end portion of the first sheet portion 11 (that is, the surface opposite to the second sheet portion 12) is cleaned of the drape body 31 by an adhesive layer such as double-sided tape. It is fixed to the surface 311. Specifically, the outer surface of the upper end portion of the first sheet portion 11 is sandwiched between the lower end portion of the auxiliary sheet 32 and the base cloth 33, and is fixed to the clean side surface of the base cloth 33. In FIG. 4, a parallel diagonal line is drawn on the region 113 of the first sheet portion 11 fixed to the clean surface 311 of the drape main body 31 (specifically, the surface on the clean side of the base cloth 33). In the following description, the region 113 is also referred to as a “fixed region 113”. The lower end portion of the auxiliary sheet 32 straddles the upper edge of the first sheet portion 11 in the vertical direction and is joined to the inner surface of the upper end portion of the first sheet portion 11 (that is, the surface on the side facing the second sheet portion 12). NS. Specifically, two slits extending upward from the lower edge of the auxiliary sheet 32 are provided, and a substantially rectangular portion 321 extending in the left-right direction between the two slits is the first sheet portion 11. It overlaps on the inner surface of the upper end portion and is fixed to the inner surface by an adhesive layer such as double-sided tape. In the following description, among the auxiliary sheets 32, the portion 321 that is laminated and fixed on the inner surface of the first sheet portion 11 is also referred to as a “laminated portion 321”.

In the example shown in FIG. 4, the width of the fixed region 113 in the left-right direction is smaller than the width of the upper end portion of the first sheet portion 11 in the left-right direction. The fixed region 113 is provided at the central portion in the left-right direction of the upper end portion of the first sheet portion 11. The left-right end portions of the upper end portion of the first sheet portion 11 are located outside the left-right side edge of the fixed region 113 in the left-right direction, and are not joined to the drape main body 31. That is, of the upper end portions of the first sheet portion 11, the central portion in the left-right direction is fixed to the drape main body 31, and both ends in the left-right direction are not fixed to the drape main body 31 and can be separated from the drape main body 31. The width of the laminated portion 321 of the auxiliary sheet 32 in the left-right direction is substantially the same as the width of the fixed region 113 in the left-right direction, and the fixed region 113 and the laminated portion 321 are located at substantially the same positions in the left-right direction. The width of the laminated portion 321 in the left-right direction may be shorter or longer than the width of the fixed region 113 in the left-right direction. The fixing of the first sheet portion 11 to the drape main body 31 is not limited to the above example, and may be performed by various methods.

The first sheet portion 11 and the second sheet portion 12 are formed of one sheet member (that is, a continuous sheet-like member). Specifically, first, one sheet member is prepared. The shape of the sheet member in the unfolded state is, for example, a substantially pentagon. Subsequently, the sheet member is rolled into a cylindrical shape (in the present embodiment, an inverted conical shape with a sharp lower end) so that the lower end becomes the above-mentioned apex. Next, by joining both ends of the sheet member in the left-right direction (that is, side edges on both the left and right sides) from the upper end to the lower end by a heat seal or the like, one of the substantially strips extending in the vertical direction. The seal portion 13 is formed.

Then, with the seal portion 13 positioned at the center on the front side (that is, a position scheduled to be the center in the left-right direction of the second seat portion 12), the portion on the front side of the tubular seat member (that is, that is). The pouch 1 in the state before use is formed by superimposing the second sheet portion 12) on the inner portion (that is, the first sheet portion 11) to form a substantially flat surface. As shown in FIG. 3, in the pouch 1 in the state before use, the above-mentioned seal portion 13 is located at the center of the second sheet portion 12. Further, the seal portion 13 is not provided on the first sheet portion 11. The first sheet portion 11 corresponds to the central portion in the left-right direction in a state where the above-mentioned one sheet member is spread out, and the second sheet portion 12 corresponds to the left and right side portions of the central portion.

The pouch 1 further includes a shape-retaining member 4 extending in the left-right direction at the upper end portion of the second seat portion 12. In the example shown in FIG. 3, the shape-retaining member 4 is a substantially strip-shaped member provided along the upper end edge of the second sheet portion 12 over a substantially overall length in the left-right direction of the second sheet portion 12. The shape-retaining member 4 may be shorter than the total length of the second seat portion 12 in the left-right direction. The vertical width of the shape-retaining member 4 is, for example, 5 mm to 15 mm. The shape of the shape-retaining member 4 is not limited to a substantially band shape, and may be variously changed to a substantially linear shape, a substantially tubular shape, or the like. As shown in FIG. 5, for example, the shape-retaining member 4 has a tubular portion formed by folding back the upper end portion of the second sheet portion 12 and joining the lower end portion of the folded portion to the facing portion. That is, it is inserted and held from the side in the cross-sectional loop-shaped portion). The shape-retaining member 4 may be arranged at the upper end portion of the second sheet portion 12 by various methods other than the above. For example, the shape-retaining member 4 may be joined to the second sheet portion 12 via an adhesive layer such as double-sided tape. The shape-retaining member 4 is formed of a plastically deformable material (for example, resin or metal). The shape-retaining member 4 has a higher rigidity than the second seat portion 12.

When the drape 3 is used, as shown in FIG. 6, the upper portion of the second seat portion 12 of the pouch 1 is pulled toward the front side, and the upper portion of the first seat portion 11 and the upper portion of the second seat portion 12 are used. Are separated. As a result, an upper liquid receiving port 21 for receiving the liquid (that is, waste liquid) from the surgical field is formed at the upper end of the pouch 1. The first sheet portion 11 and the second sheet portion 12 are separated from the upper end portion to the lower end portion, whereby the pouch 1 becomes substantially cylindrical.

When the upper liquid receiving port 21 is formed, the shape-retaining member 4 is plastically deformed as the second sheet portion 12 is separated from the upper first sheet portion 11 to form the shape of the upper liquid receiving port 21. maintain. Specifically, the left-right central portion of the shape-retaining member 4 provided on the second seat portion 12 is curved in a substantially arc shape so as to project in a direction away from the first seat portion 11.

In the pouch 1, the seal portion 13 provided at the center of the second sheet portion 12 in the left-right direction projects toward the front side substantially perpendicular to the portion of the second sheet portion 12 near the seal portion 13. The seal portion 13 has a higher rigidity than the second seat portion 12. The seal portion 13 acts as a girder structure that suppresses deformation of the second sheet portion 12 due to its own weight or the like. As a result, the second sheet portion 12 is prevented from hanging down due to its own weight or the like. As a result, the shape of the upper liquid receiving port 21 of the pouch 1 is maintained, and the inner surfaces of the first sheet portion 11 and the second sheet portion 12 are prevented or suppressed from sticking to each other (that is, in close contact with each other).

The waste liquid flowing from the upper liquid receiving port 21 of the pouch 1 flows downward in the cylindrical space between the first sheet portion 11 and the second sheet portion 12, and flows downward from the lower drain port 22 to the outside of the pouch 1. Is discharged. The waste liquid discharged from the lower drainage port 22 is guided to a predetermined waste liquid tank or the like via, for example, a drainage hose (not shown).

As described above, the pouch 1 includes a first seat portion 11 and a second seat portion 12. The first seat portion 11 is attached in the vicinity of the opening 310 of the drape main body 31. The second sheet portion 12 has substantially the same shape as the first sheet portion 11 and overlaps the first sheet portion 11 in a state before use. Further, the side edge portions on both sides of the second seat portion 12 in the left-right direction are continuous with the first seat portion 11. The first sheet portion 11 and the second sheet portion 12 are formed by rolling one sheet member into a cylindrical shape in the left-right direction and joining both ends in the left-right direction. The band-shaped seal portion 13 extending in the vertical direction formed by joining both ends of the single sheet member in the left-right direction is located at the center of the second sheet portion 12 in the left-right direction in the state before use. ..

As described above, in the pouch 1, the seal portion 13 acts as a girder structure that suppresses deformation of the second sheet portion 12 due to its own weight or the like. Therefore, it is suppressed that the second sheet portion 12 hangs down due to its own weight or the like. As a result, it is possible to prevent or prevent the inner surfaces of the first sheet portion 11 and the second sheet portion 12 from sticking to each other (that is, the inner surfaces of the sheet portions forming the pouch 1 stick to each other).

In the pouch 1, it is preferable that the lower drainage port 22 is provided at the lower end portion. In the pouch 1, as described above, the sticking of the first sheet portion 11 and the second sheet portion 12 can be suppressed, so that the flow of the waste liquid flowing from the upper liquid receiving port 21 is suppressed. Will be done. Therefore, the waste liquid can be smoothly drained from the lower drain port 22.

As described above, preferably, in the state before use, the width of the lower portion of the second seat portion 12 in the left-right direction gradually decreases toward the lower side, and the angle formed by the left and right side edges of the lower portion of the second seat portion 12. α is 60 ° or more and 120 ° or less. By setting the angle α to 120 ° or less, the width of the upper portion of the second sheet portion 12 becomes wider, and it is possible to further suppress the upper portion from hanging due to its own weight. Further, the waste liquid flowing from the upper liquid receiving port 21 can be more smoothly flowed down to the lower end portion of the pouch 1. From the viewpoint of maintaining the open state of the upper liquid receiving port 21 and facilitating the flow of waste liquid, the angle α is more preferably 100 ° or less. On the other hand, when the angle α is 60 ° or more, the width of the upper liquid receiving port 21 in the left-right direction can be increased to some extent or more. From the viewpoint of securing the width of the upper liquid receiving port 21, the angle α is more preferably 80 ° or more.

As described above, the first sheet portion 11 and the second sheet portion 12 are preferably made of a polyolefin resin. As described above, by forming the first sheet portion 11 and the second sheet portion 12 with a relatively hard material, the sagging of the second sheet portion 12 can be further suppressed. From this point of view, the first sheet portion 11 and the second sheet portion 12 are more preferably made of polyethylene, and even more preferably made of linear low-density polyethylene.

As described above, the drape 3 includes the drape main body 31 having an opening 310 that exposes the surgical field, and the pouch 1 that is fixed in the vicinity of the opening 310 on the clean surface 311 of the drape main body 31 and receives the liquid from the surgical field. , Equipped with. In the drape 3, as described above, it is possible to prevent or suppress the inner surfaces of the first sheet portion 11 and the second sheet portion 12 of the pouch 1 from sticking to each other. Therefore, medical procedures such as knee joint surgery using the drape 3 can be easily and smoothly performed.

The pouch 1, drape 3 and disposable medical device set 6 described above can be modified in various ways.

For example, the shape of the pouch 1 before use may be changed in various ways. For example, in the pouch 1 before use, the angle α formed by the left and right side edges of the lower portions of the first seat portion 11 and the second seat portion 12 may be larger than 120 ° or less than 60 °. good. Further, the shape of the pouch 1 before use (that is, the shape of the first sheet portion 11 and the second sheet portion 12) is not limited to a substantially pentagonal shape, and may be changed in various ways. The shape of the pouch 1 before use may be, for example, a substantially triangular shape or a substantially rectangular shape.

The material of the pouch 1 is not necessarily limited to the polyolefin-based resin, and may be changed in various ways.

The seal portion 13 of the pouch 1 may be formed by various joining methods other than heat sealing.

Inside the pouch 1 (that is, between the first sheet portion 11 and the second sheet portion 12), a mesh member or a sheet having a large number of holes for catching solid matter in a liquid from the surgical field is formed. Members may be provided. Further, in the pouch 1, the lower drainage port 22 may be omitted.
