Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

To facilitate understanding of the scheme of the present application, the spline curves and arrows used in the drawings are explained here: the components indicated by the spline curves without arrows are solid components, that is, components with solid structures; the components indicated by the spline curves with arrows are virtual components, that is, components without solid structures.

Please refer to Figures 1 to 12. The present application provides a sterilization instrument box 1 for use with a hydrogen peroxide sterilization device. The sterilization instrument box 1 mainly assists the sterilization chamber 3 in sterilizing the pipes of some medical devices with elongated holes, such as pipes of medical devices with elongated holes such as hose endoscopes. In addition, in addition to assisting the sterilization chamber 3 in sterilization, after the sterilization of the sterilization chamber 3 is completed, the sterilization instrument box 1 can also store and transport the sterilized medical devices, and can effectively prevent external bacteria and other contaminants from causing secondary contamination to the medical devices. The sterilization instrument box 1 introduced in the present application is mainly a structure set for the sterilization of hose endoscopes. Of course, it can also be applied to pipes of other medical devices with elongated holes without specific limitation. In order to facilitate understanding of the structure and working principle of the sterilization instrument box 1, it is introduced in detail below:

The sterilization instrument box 1 is mainly used for placing the hose endoscope 2 to be sterilized and disinfecting the hose endoscope 2 to be sterilized. The hose endoscope 2 to be sterilized includes at least one lumen to be sterilized and one lumen that does not need to be sterilized. The sterilization instrument box 1 used in conjunction with the hydrogen peroxide sterilization equipment includes a box body 11 and a box cover 12. The box cover 12 is detachably covered on the box body 11. A plurality of external functional interfaces 13 are provided on the outer wall of the box body 11. A plurality of internal functional connectors 14 are provided on the inner wall of the box body 11. Each external functional interface 13 is connected to a corresponding internal functional connector 14. At least one internal functional connector 14 is connected to a lumen to be sterilized, and one internal functional connector 14 is connected to a lumen that does not need to be sterilized.

The technical solution provided by the present application is mainly to set a plurality of external functional interfaces 13 and a plurality of internal functional connectors 14 on the side wall of the box body 11, and each external functional interface 13 is connected to a corresponding internal functional connector 14 through the side wall of the box body 11. The external functional interface 13 is connected to the corresponding connecting pipe in the sterilizer, and the vaporized hydrogen peroxide sterilization gas is delivered to the external functional interface 13 through the connecting pipe, and then delivered to the internal functional connector 14 connected to the external functional interface 13. Here, if the internal functional connector 14 is not connected to the corresponding hose endoscope 2 to be sterilized, the vaporized hydrogen peroxide sterilization gas is directly introduced into the sterilization instrument box 1 to sterilize the interior of the sterilization instrument box 1 and the surface of the instrument placed in the sterilization instrument box 1. In this embodiment, a plurality of internal functional connectors 14 can be classified according to the functions of the internal functional connectors 14, such as a plurality of internal functional connectors 14 can include a sterilization internal functional connector and a balancing internal functional connector. The sterilization internal functional connector is mainly used to receive hydrogen peroxide and discharge the hydrogen peroxide gas into the lumen that needs to be sterilized, while the balancing internal functional connector is mainly used to pass air into the lumen that does not need to be sterilized, balance the air pressure in the lumen that does not need to be sterilized with the air pressure in the box body, and avoid damage to the lumen that does not need to be sterilized due to unbalanced air pressure. If the lumen that needs to be sterilized of the hose endoscope 2 to be sterilized is connected with the corresponding sterilization internal functional connector, and the lumen that does not need to be sterilized is connected with the corresponding balancing internal functional connector, the vaporized sterilization gas can be directly passed into the lumen that needs to be sterilized, and the inner wall of the lumen that needs to be sterilized and the entire lumen inside can be sterilized, so that the lumen that needs to be sterilized can achieve a better sterilization effect, and compared with the prior art, the sterilization speed of the lumen that needs to be sterilized will also be significantly improved. Subsequently, the vaporized sterilizing gas flows out into the box body 11 through the lumen to be sterilized, and gradually fills the box body 11, sterilizing the internal environment of the box body 11 and the surface of the hose endoscope 2 to be sterilized. Compared with the prior art method of introducing hydrogen peroxide into the box body 11, first sterilizing the surface of the box body 11 and the instruments in the box body 11, and then waiting for the hydrogen peroxide to drift into the lumen to be sterilized, the technical solution of the present application sterilizes the interior of the lumen more thoroughly and fully, and the sterilization speed is faster, without waiting for the hydrogen peroxide gas to diffuse, and can also ensure the sterilization of the inside of the box body 11 and the surface of the hose endoscope. The balanced internal functional connector is connected to a lumen that does not need to be sterilized, and clean gas is introduced into the lumen that does not need to be sterilized, mainly because the end of the lumen that does not need to be sterilized away from the balanced internal functional connector is in a closed state, in order to ensure that the air pressure in the lumen that does not need to be sterilized is balanced with the external air pressure, and to avoid damage to the lumen that does not need to be sterilized.

It should also be noted that a first sealing ring is provided on the inner wall of the box cover 12. When the box cover 12 is buckled on the box body 11, the side walls of the box cover 12 and the side walls of the box body 11 can jointly squeeze the first sealing ring, thereby sealing the gap between the box cover 12 and the box body 11.

Further, at least one lock catch is provided on the opposite side wall of the box cover 12, and a lock seat adapted to the lock catch is provided on the box body 11, and the lock catch and the lock seat cooperate to fix the box cover 12 on the box body 11. The combination of the lock catch and the lock seat is an existing lock, which will not be described in detail here. In this embodiment, two lock catches are provided at intervals on the opposite side walls of the box cover 12, so that the box cover 12 can be more tightly covered on the box body 11.

Furthermore, a silicone pad 111 is laid in the box body 11 , and the soft tube endoscope 2 to be sterilized is placed on the silicone pad 111 to avoid direct contact between the soft tube endoscope 2 to be sterilized and the box body 11 .

Specifically, a plurality of external functional interfaces 13 include a water supply and gas interface, a biopsy interface and a side leakage interface, and a plurality of internal functional joints 14 include a water supply and gas joint, a biopsy joint and a side leakage joint. Among them, the water supply and gas joint is connected to the water supply and gas interface, the biopsy joint is connected to the biopsy interface, the side leakage joint is connected to the side leakage interface, the lumen to be sterilized is connected to the end of the water supply and gas joint away from the water supply and gas interface or is connected to the end of the biopsy joint away from the biopsy interface, and the lumen that does not need to be sterilized is connected to the end of the side leakage joint away from the side leakage interface. Here, the water supply and gas interface and the biopsy interface are both connected to an external device for transporting hydrogen peroxide, and the water supply and gas joint and the biopsy joint are each connected to a lumen that needs to be sterilized, and the lumen that needs to be sterilized is sterilized. The side leakage joint is connected to the lumen that does not need to be sterilized mainly to introduce air into the lumen that does not need to be sterilized to maintain the balance of pressure inside and outside the lumen that does not need to be sterilized. The lumen that needs to be sterilized mainly refers to the lumen that needs to be sterilized, such as the lumen that needs to be inserted into the human body; the lumen that does not need to be sterilized mainly refers to the lumen that does not need to be sterilized, such as the lumen that does not need to be inserted into the human body. The specific type of lumen is not limited in this application and can be selected according to different flexible tube endoscopes.

Furthermore, a plurality of reserved joints and reserved interfaces corresponding to the reserved joints may be provided on the side wall of the box body 11, so as to facilitate the adaptation to various types of instruments with different numbers of hoses and expand the scope of application of the instrument box. In addition, the plurality of reserved joints and reserved interfaces are arranged close to the aforementioned plurality of functional joints and functional interfaces, so as to facilitate the connection and use of the instruments to be sterilized.

In some embodiments, as shown in FIGS. 1 to 3 , a sealing member 15 is provided at a plurality of external functional interfaces 13. The sealing member 15 is detachably sealed with the external functional interface 13, and is mainly used to block the external functional interface 13. For example, when the sterilization instrument box 1 is not placed in the sterilization chamber 3 or does not need to be connected to an external device, the sealing member 15 is needed to block and seal the external functional interface 13 to prevent external air or microorganisms such as bacteria from entering the box body 11 through the interface, thereby contaminating the box body 11 and the medical devices stored in the box body 11.

Specifically, the seal 15 includes a plug 151, a flexible connection belt 152 and a fixing seat 153. The fixing seat 153, the plug 151 and the flexible connection belt 152 are all made of soft rubber material, have good elastic deformation characteristics, and can adapt to more interface calibers and different lengths of the external functional interface 13 itself. The fixing seat 153 is connected to the plug 151 through the flexible connection belt 152, and the fixing seat 153 is fixed on the outer wall of the box body 11. The specific position is not limited. In this embodiment, it is preferred that the fixing seat 153 is sleeved on the outer peripheral edge of the external functional interface 13 and fixed on the side wall of the box body 11, so that the seal 15 is located near the external functional interface 13, which is more convenient and effectively shortens the length of the flexible connection belt 152. The plugging head 151 is detachably sealed with the external functional interface 13 , specifically, the plugging head 151 is directly inserted into the external functional interface 13 and relies on the elastic characteristics of the plugging head 151 to fit tightly with the inner wall of the external functional interface 13 to achieve a plugging and sealing effect.

Since the box body 11 may be loaded with different types and models of hose endoscopes 2 to be sterilized or other medical devices with slender lumens, in order to avoid damage to the hose, too fast introduction of hydrogen peroxide gas into the hose, incomplete sterilization, or too little introduction of gas into the hose, incomplete sterilization, etc., different hoses need to adapt to different gas flow rates and flow rates. For this reason, in this embodiment, the external function interface 13 not only has the function of connecting external equipment and the internal function connector 14, but also has the function of adjusting the flow rate to adapt to different types of hoses. To facilitate understanding of the specific structure of the external function interface 13 with the function of adjusting the flow rate, it is described in detail below:

Please refer to Figures 3 to 6, the external function interface 13 includes:

The first circulation member 131 has a first circulation channel 1311 formed therein, and one end of the first circulation member 131 is tapered, and the first circulation channel 1311 extends to a position close to the end but is not connected to the end. The first circulation member 131 has a plurality of small holes formed in a circumferential direction near the end, and the small holes are connected to the first circulation channel 1311, so that the gas introduced into the first circulation channel 1311 can flow out of the first circulation channel 1311 through the small holes.

The second circulation member 132 has a receiving chamber 1321 communicating with the first circulation channel 1311 and a second circulation channel 1322 communicating with the receiving chamber 1321. A portion of the first circulation member 131 is located in the receiving chamber 1321 of the second circulation member 132, and a small hole communicating with the first circulation channel 1311 is located in the receiving chamber 1321. Through the small hole, the gas in the first circulation channel 1311 flows into the receiving chamber 1321, and then communicates with the second circulation channel 1322 through the receiving chamber 1321, and flows into the second circulation channel 1322.

The conical end of the first circulation member 131 is plugged into the second circulation channel 1322, and the end of the first circulation member 131 away from the conical end is threadedly engaged with the end of the second circulation member 132 away from the second circulation channel 1322. By threading the first circulation member 131 and the second circulation member 132, the first circulation member 131 can be rotated to control the movement of the first circulation member 131 relative to the second circulation member 132 in the axial direction of the first circulation channel 1311, thereby controlling the conical end to be inserted into the second circulation channel 1322 or away from the second circulation channel 1322. The conical end mainly refers to the outer edge portion of the end being inclined, and the diameter of the end gradually decreases along the direction from the first circulation member 131 to the second circulation member 132, that is, the end is tapered, and there is no limitation as to whether the cone of the end is conical or truncated cone, as long as the diameter gradually decreases. By cooperating the tapered end with the second circulation channel 1322 whose diameter does not change, when the end moves toward the second circulation channel 1322, the gap between the end and the inner wall of the second circulation channel 1322 gradually decreases, and the flow area flowing from the accommodating cavity 1321 into the second circulation channel 1322 gradually decreases, thereby reducing the amount of gas flowing into the second circulation channel 1322 per unit time; on the contrary, if the tapered end moves in a direction away from the second circulation channel 1322, the gap between the tapered end and the inner wall of the second circulation channel 1322 gradually increases, and the gas flow rate also increases. Through the above-mentioned structural setting, those skilled in the art can realize the change of gas flow rate by rotating the first circulation member 131, and conveniently control the flow rate to adapt to the hoses in the different hose endoscopes 2 to be sterilized. The structure of adjusting the flow rate of the external function interface 13 has at least one beneficial effect: the external function interface 13 can adjust the flow rate at any time, whether the external device is connected to the external function interface 13 or not, the flow rate can be adjusted, and the flow rate can be controlled in real time. However, it should be noted that if the sterilization instrument box 1 is placed in the sterilization chamber 3, real-time adjustment cannot be performed.

In addition to the flow rate adjustment structure described in the above embodiment, in another embodiment, referring to FIGS. 7 to 11 , the external function interface 13 includes:

The first interface 133 is connected to an external device, such as a pipeline for conveying hydrogen peroxide gas or other pure gas, which is not limited.

The flow rate regulating member 134 is mainly used to regulate the flow rate of the gas flowing through the external functional interface 13 per unit time. One end of the flow rate regulating member 134 is connected to the first interface 133 to regulate the flow rate of hydrogen peroxide gas or other gases entering the flow rate regulating member 134.

The second interface 135, one end of which is connected to the end of the flow regulating member 134 away from the first interface 133, and the other end extends into the box body 11 and is connected to the internal functional joint 14, so that the first interface 133 and the second interface 135 are connected to each other through the flow regulating member 134, so that the first interface 133 receives input gas from an external device, which can flow into the second interface 135 through the flow regulating member 134, and then flow into the tube cavity and the box body 11 through the second interface 135. In addition, by using the flow regulating member 134, the gas flow can be adjusted to the optimal flow into the corresponding tube cavity according to the requirements of the diameter and structure of different tube cavities. It should be noted that, in order to facilitate disassembly and assembly, the connection between the first interface 133, the second interface 135 and the flow regulating member 134 is a threaded connection.

The fixing member 136 is sleeved on the second interface 135 and is threadedly connected to the second interface 135. The fixing member 136 can move along the axial direction of the second interface 135 through the thread. When the fixing member 136 moves to a certain position, the fixing member 136 abuts against the inner wall of the box body 11, and one side of the second interface 135 abuts against the outer wall of the box body 11, thereby realizing that the external functional interface 13 is fixed on the side wall of the box body 11.

Furthermore, in order for those skilled in the art to more clearly understand the method and principle of the flow rate adjustment, the specific structure of the flow rate adjustment member 134 is described in detail below:

The flow rate adjustment member 134 includes:

The barrel 1341 has two ends connected to the first interface 133 and the second interface 135 respectively, and the connection method is threaded connection. Both ends of the barrel 1341 are provided with external threads, and the first interface 133 and the second interface 135 are respectively provided with internal threads at the connection with the barrel 1341, so that the threaded combination is convenient for disassembly, cleaning, replacement, etc.;

The partition 1342 is arranged in the cylinder 1341 and the front surface of the partition 1342 is perpendicular to the axial direction of the cylinder 1341, that is, the placement direction of the partition 1342 is perpendicular to the direction of gas flow, which has a certain obstruction effect on the flow of gas, and the fixing relationship between the partition 1342 and the cylinder 1341 can be a variety of fixing methods such as snap-on, embedded and integrated molding, which are not specifically limited. In addition, in order to allow the gas to flow through the partition 1342, a plurality of through holes 13421 are opened on the partition 1342. Here, the shape of the partition 1342 is the same as the cross-sectional shape of the cylinder 1341, both of which are circular.

The adjusting component 1343 is threadedly connected to the center of the partition 1342 and is used to adjust the number of the through holes 13421 covered along the axial direction, so as to achieve the purpose of adjusting the gas flow rate.

Furthermore, the adjustment component 1343 further includes:

The rotating shaft 13431 has a starting end and a tail end, and the tail end is fixedly connected to the partition plate 1342, which can be an interference fit or a threaded connection. In this embodiment, the threaded connection is adopted;

Several movable pieces 13432 are all rotatably sleeved on the rotating shaft 13431 and overlapped in the axial direction. Each movable piece 13432 can independently rotate around the rotating shaft 13431 or one movable piece 13432 can drive the adjacent movable piece 13432 to rotate around the rotating shaft 13431. The specific method is not limited. In this embodiment, each movable piece 13432 can independently rotate around the rotating shaft 13431, which can effectively reduce the connection structure between adjacent movable pieces 13432, and the structure is simpler. Several movable pieces 13432 are located between the beginning of the cylinder 1341 and the partition 1342, and are subjected to the squeezing force between the beginning and the partition 1342, so that friction is generated between the movable piece 13432 and the partition 1342, and friction is generated between adjacent movable pieces 13432, so as to avoid that after the movable pieces 13432 rotate to a certain position, they are affected by gravity and cannot keep the position still, affecting the regulation of the flow rate.

It should also be noted that, for the plurality of through holes 13421 opened on the partition 1342, in some embodiments, the plurality of through holes 13421 are arranged rotationally symmetrically along the center of the partition 1342, and there are a total of six through holes 13421, and the six through holes 13421 are arranged rotationally symmetrically along the center, so that the degree of flow adjustment is divided into six levels, that is, one through hole 13421 represents one level, the first level represents that the gas can flow, and the flow is the smallest, the sixth level represents that the gas can flow, and the flow is the largest, and the flow from the second to the fifth level increases step by step. Correspondingly, the number of the plurality of movable sheets 13432 is set corresponding to the number of through holes 13421, and each movable sheet 13432 can be used to cover a through hole 13421, so as to achieve visual flow adjustment, which is more convenient for the staff to select the flow adjustment of the corresponding medical device.

The following is the working process of the entire circulation adjustment:

After determining the medical device to be sterilized, the technicians in this field can select the flow rate level corresponding to the medical device according to the optimal gas flow rate data required for sterilizing various medical devices in the experimental stage. For example, if a level 3 flow rate is required, the staff can rotate three of the movable pieces 13432 in the circumferential direction of the rotating shaft 13431 in sequence, and move the three movable pieces 13432 to the three through holes 13421 respectively, so as to achieve corresponding shielding of the three through holes 13421 and restrict the smooth outflow of gas from the three through holes 13421. In the whole process of moving the movable piece 13432, the fingers can be directly inserted into the barrel 1341 and the movable piece 13432 can be moved (the main surface of the movable piece 13432 is provided with a protrusion to assist the fingers in moving the movable piece 13432), or a moving rod can be inserted into the moving hole of the movable piece 13432 to move it. The selection can be made by the staff without limitation. The dial hole of the movable sheet 13432 is arranged on the main surface of the movable sheet 13432 and is located near the edge of the movable sheet 13432. Of course, before dialing the movable sheet 13432, it is necessary to unscrew the first interface 133 from the flow regulating member 134 to open the port of the cylinder 1341 connected to the first interface 133.

In some embodiments, as shown in FIG. 2 , a plurality of fixing frames 16 are provided in the box body 11 , and a plurality of elastic clamping positions are provided on the fixing frames 16 , which are adapted to be clamped with the hose to be sterilized to fix the medical device to be sterilized, such as a hose endoscope.

In some embodiments, a limiting frame 17 and a perspective window 18 are provided on the side wall of the box body 11, a gap is formed between the limiting frame 17 and the side wall, and the limiting frame 17 is open toward the box cover 12, and a bacteria isolation component 19 is provided in the gap, and the bacteria isolation component 19 covers the perspective window 18. The number of the perspective windows 18 and the limiting frame 17 is the same. In some embodiments, there are multiple perspective windows 18, and in other embodiments, there is only one perspective window 18. A second sealing ring is provided on the peripheral wall of the perspective window 18, and the cross section of the second sealing ring is a U-shaped structure. When the second sealing ring is installed on the perspective window 18, the second sealing ring wraps part of the peripheral wall of the perspective window 18. The bacteria isolation component 19 is provided in the gap and can be drawn out from the opening of the limiting frame 17. The bacteria isolation component 19 includes a bacteria isolation material 191 and a fixing plate 192. The fixing plate 192 is provided with an opening that matches the size of the perspective window 18. When the fixing plate 192 is installed in place, the perspective window 18 can overlap with the opening. The bacteria-isolating material 191 is arranged at the opening and is bonded or clamped to the inner side wall forming the opening. The bacteria-isolating material 191 is a disposable consumable, such as Tyvek, which is breathable and can form a biological barrier to isolate bacteria. During the sterilization process, hydrogen peroxide gas and air can flow from the sterilization box into the sterilization chamber 3 through the bacteria-isolating material 191, and then be extracted through the vacuum device 6. Medical devices, such as endoscopes, need to be sterilely stored after being disinfected and sterilized in the sterilization equipment. If the endoscope is directly taken out of the sterilization chamber 3 and transferred to a storage device, the endoscope is exposed to the air during the transfer process, which will cause secondary contamination. Therefore, in the present application, the sterilization box is used as a storage device for the endoscope to avoid secondary contamination of the endoscope.

In order to facilitate the staff to understand how the sterilization instrument box 1 is used in conjunction with the hydrogen peroxide sterilization device, the structural relationship and working process between the sterilization instrument box 1 and the hydrogen peroxide sterilization device are described in detail below:

Please refer to Figure 12, a hydrogen peroxide sterilization device includes a main body, on which a sterilization chamber 3, a purification device 4, a liquid adding device 5 and a vacuum device 6 are arranged, and the purification device 4, the liquid adding device 5 and the vacuum device 6 are all connected to the sterilization chamber 3. A shelf 31 and an electrode net 32 are arranged in the sterilization chamber 3, and a first connector 33 and a second connector are also arranged in the sterilization chamber 3; one end of the first connector 33 penetrates the side wall of the sterilization chamber 3 and is connected to the output end of the purification device 4, and the other end of the first connector 33 is connected to a part of the external functional interface 13 of the box body 11. One end of the second connector penetrates the side wall of the sterilization chamber 3, and is provided with a gas supply component, which can open and close the second connector and can input clean gas into the second connector. The other end of the second connector penetrates the side wall of the sterilization chamber 3 and is connected to the vacuum device 6, and a first connector connected to a part of the external functional interface 13 is arranged on the peripheral wall of the second connector. After the sterilization hose endoscope 2 is placed in the sterilization instrument box 1, and the sterilization instrument box 1 is connected to the first connector 33 and the second connector on the outside and to the corresponding lumen of the sterilization hose endoscope 2 on the inside, the door of the sterilization chamber 3 is closed to make the inside of the sterilization chamber 3 a sealed environment. Then, the air in the sterilization chamber 3, the lumen of the endoscope that does not need to be sterilized, the box body 11, and the lumen that needs to be sterilized (the lumen that needs to be sterilized is connected to the box body 11, and the air in the lumen that needs to be sterilized can be extracted by extracting the air in the box body 11) is simultaneously extracted through the vacuum device 6, so that the inside is in a vacuum state. After the vacuuming work is completed, the purification device 4 and the gas transmission component are opened at the same time, and the hydrogen peroxide gas in the purification device 4 enters the sterilization chamber 3 through the first connecting piece 33, the external functional interface 13, the internal functional joint 14 and the sterilization lumen in turn, so that the hydrogen peroxide gas can be distributed throughout each part of the sterilization lumen, ensuring the sterilization effect of the inner and outer walls of the sterilization lumen; the outside air is filtered by the gas transmission component and enters the non-sterilization lumen through the second connecting piece, the external functional interface 13, and the internal functional joint 14, so that the air pressure in the non-sterilization lumen is consistent with the air pressure in the sterilization chamber 3, avoiding the rupture of the tube wall of the non-sterilization lumen. In addition, the non-sterilization lumen of the endoscope is connected to the second connecting piece, so that the hydrogen peroxide gas in the sterilization chamber 3 cannot enter the non-sterilization lumen of the endoscope, avoiding the residual hydrogen peroxide gas inside.
