Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to an enzyme solution cartridge for an endoscope brush. Background Art

[0002] In the medical field, endoscopes are commonly used diagnostic and treatment tools, and their cleaning and disinfection are important links to ensure medical safety and avoid cross-infection. As a key tool for cleaning the endoscope channel, an endoscope brush needs to be used in conjunction with an enzyme solution during the cleaning process to effectively remove residues and microorganisms in the channel.

[0003] Firstly, the traditional enzyme solution supply method often requires on-site preparation and filling of the enzyme solution, which not only increases the complexity and time cost of the operation, but also easily leads to inaccurate preparation ratio of the enzyme solution due to human factors, thus affecting the cleaning effect. Secondly, since the endoscope brush needs to be manually held to clean the endoscope tube, the amount of enzyme solution that can be stored in the endoscope brush should not be too much. Therefore, the convenience of the connection between the enzyme solution supply system and the endoscope brush needs to be improved to avoid the need for additional tools or complex operation steps to achieve connection and disconnection, resulting in poor work efficiency and increasing the workload of medical staff.

[0004] In view of this, there is a need to provide an enzyme solution cartridge for an endoscope brush to improve the cleaning efficiency and convenience of use of the endoscope brush. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an enzyme solution cartridge for an endoscope brush in view of the above-mentioned defects of the prior art.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:

The blocking portion cooperates with the inner side of the mouth of the tank body to close and open the mouth of the tank body.

[0010] As an improvement of the enzyme liquid cartridge, the reset members are provided in multiple groups, and the multiple groups of reset members are circumferential and evenly spaced, and are located between the movable sleeve and the tank body.

[0011] As an improvement of the enzyme liquid cartridge, it further includes a first sealing member arranged at the outer end of the movable sleeve, wherein the first sealing member is used to reduce the gap between the movable sleeve and the endoscope brush when they are abutted and installed.

[0012] As an improvement of the enzyme liquid cartridge, it further includes a second sealing member provided at one end of the movable sleeve close to the tank body, wherein the second sealing member is used to reduce the gap between the tank body and the movable sleeve when the enzyme liquid cartridge is in use.

[0013] As an improvement of the enzyme liquid cartridge, it further includes a limiting member, which is arranged at the tank mouth and located between the movable sleeve and the tank body to prevent the movable sleeve from moving, so that the blocking member is always in a closed state.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Such as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown in the figure, an enzyme solution cartridge for an endoscopic brush includes a tank body 1, a movable sleeve 2 sleeved on the mouth of the tank body 1, and a reset member 3 for driving the movable sleeve 2 to move and reset. The movable sleeve 2 is provided with a sealing member 4, and the sealing member 4 is inserted into the tank body 1 and can close the mouth of the tank body 1 by moving along with the movable sleeve 2. Specifically, the tank body 1 is a container for storing enzyme solution, and the movable sleeve 2 is sleeved on the mouth of the tank body 1 and can move along the mouth of the tank.

[0030] When the enzyme solution cartridge is docked and connected to the endoscopic brush, the mouth of the tank body 1 is first aligned with the communication port 84 of the endoscopic brush. Then, after the movable sleeve 2 on the mouth of the tank is initially abutted against the communication port 84, continue to apply pressure to the tank body 1 in the direction of the communication port 84; the movable sleeve 2 is then squeezed and moves towards the tank body 1, the reset member 3 is squeezed and deformed, and the sealing member 4 moves along with the movable sleeve 2 and disengages from the inner side of the mouth of the tank body 1, so that the mouth of the tank is in an open state, thereby achieving the connection between the tank body 1 and the communication port 84 of the endoscopic brush, and allowing the enzyme solution in the tank body 1 to flow into the endoscopic brush. When it is necessary to disassemble the enzyme solution cartridge from the endoscopic brush, the enzyme solution cartridge is disengaged from the communication port 84 of the endoscopic brush, the connection is disconnected, the reset member 3 is reset by its resilience, drives the movable sleeve 2 to move and reset, and the sealing member 4 is driven by the movable sleeve 2 to abut against the inner side of the mouth of the tank body 1 again, so that the mouth of the tank is in a closed state, preventing the enzyme solution from flowing out of the tank body 1. In this way, the automatic connection after the enzyme solution cartridge is docked with the endoscopic brush and the automatic closing of the mouth of the tank after the enzyme solution cartridge is disassembled from the endoscopic brush are achieved, improving the simplicity of use and the assembly efficiency.

[0031] It should be noted that after the enzyme solution cartridge is connected to the endoscopic brush, the endoscopic brush can extract the enzyme solution in the tank body 1 through the internal liquid infusion mechanism and transport it to the brush head at the end of the endoscopic brush, realizing the automatic application of the enzyme solution when the endoscopic brush cleans the endoscopic tube. At the same time, there is no need to prepare the enzyme solution on site. When the enzyme solution in the tank body 1 is used up, just replace it with a new enzyme solution cartridge. The liquid infusion mechanism includes but is not limited to a pump delivery structure.

[0032] In some embodiments of the present application, the reset member 3 includes an elastic member 31 and a guide rod 32 provided on the tank body 1. The movable sleeve 2 has a guide hole 21 for inserting the guide rod 32, and the elastic member 31 is arranged in the guide hole 21 for driving the movable sleeve 2 to move and reset. Specifically, the reset member 3 drives the movable sleeve 2 to reset, so that the sealing member 4 abuts against the inner side of the mouth of the tank body 1 again, realizing the automatic closing of the mouth of the tank and preventing the enzyme solution from flowing out of the tank body 1. The automatic reset function of the reset member 3 enables the enzyme solution cartridge to be automatically closed after disassembly without manual operation, improving the convenience of use; at the same time, it also reduces the risk of damage caused by improper manual operation, thereby prolonging the service life of the enzyme solution cartridge. The setting of the reset member 3 provides a stable guiding and reset mechanism for the movable sleeve 2 during movement, enhancing the stability and reliability of the overall structure of the enzyme solution cartridge.

[0033] In some embodiments of the present application, the plugging member 4 includes a connecting rod 41 and a plugging portion 42 connected to the end of the connecting rod 41. The plugging portion 42 cooperates with the inner side of the tank opening of the tank body 1 and can close and open the tank opening. Specifically, the plugging portion 42 cooperates with the inner side of the tank opening of the tank body 1, and the movement of the movable sleeve 2 is used to control the contact or separation between the plugging portion 42 and the tank opening. When the enzyme solution cartridge is docked with the endoscope brush, the movable sleeve 2 is squeezed and moves towards the tank body 1, and the plugging member 4 moves with the movable sleeve 2 and separates from the inner side of the tank opening of the tank body 1, and the tank opening is opened to allow the enzyme solution to flow out. When the enzyme solution cartridge is disconnected from the endoscope brush, the reset member 3 causes the movable sleeve 2 to reset through the resilience, and the plugging member 4 abuts against the inner side of the tank opening of the tank body 1 again to close the tank opening. It realizes the automatic connection after the enzyme solution cartridge is docked with the endoscope brush and the automatic sealing after disconnection, improving the simplicity and efficiency of use. Through the sealing design, the cleanliness and effectiveness of the enzyme solution in the tank body 1 are maintained, and external contamination is avoided.

[0034] More specifically, for the used empty enzyme solution cartridge, the movable sleeve 2 can be manually squeezed to move, so that the tank opening of the tank body 1 is in an open state, and then the prepared enzyme solution can be input into the tank body 1 through the tank opening. After the input is completed, release the movable sleeve 2, and the reset member 3 drives the movable sleeve 2 and the plugging portion 42 to reset, so that the tank body 1 returns to a closed and sealed state, which is convenient for storing the enzyme solution cartridge filled with the enzyme solution. Multiple enzyme solution cartridges can be provided for users to replace.

[0035] In some embodiments of the present application, there are four groups of reset members 3, and the four groups of reset members 3 are arranged in a surrounding and evenly spaced manner between the movable sleeve 2 and the tank body 1. Specifically, the four groups of reset members 3 are evenly distributed around the space between the movable sleeve 2 and the tank body 1, ensuring that the movable sleeve 2 can receive uniform reset forces from four directions during the movement process. Since the four groups of reset members 3 are arranged in a surrounding and evenly spaced manner, the movable sleeve 2 can remain stable during the reset process, avoiding shaking or jamming phenomena caused by uneven reset. In addition, the uniform distribution of the reset forces reduces the friction and wear between the movable sleeve 2 and the tank body 1, thereby extending the service life of the enzyme solution cartridge.

[0036] In other embodiments, according to requirements, the number of the reset members 3 can also be set to include but not limited to 2 groups, 3 groups, 5 groups or 6 groups.

[0037] In some embodiments of the present application, it further includes a first seal 5 disposed at the outer end of the movable sleeve 2. The first seal 5 is used to reduce the gap when the movable sleeve 2 is in butt-joint installation with the endoscopic brush. Specifically, the first seal 5 is disposed at the outer end of the movable sleeve 2. When the enzyme solution cartridge is in butt-joint installation with the endoscopic brush, the first seal 5 can closely adhere to the connection port or corresponding part of the endoscopic brush. The first seal 5 can effectively reduce the gap between the movable sleeve 2 and the endoscopic brush, preventing the enzyme solution from leaking from the gap during transmission. In addition to the sealing function, the first seal 5 can also provide a certain amount of friction to help the enzyme solution cartridge be more stably connected to the endoscopic brush, preventing accidental detachment due to external force during use.

[0038] By reducing the gap between the movable sleeve 2 and the endoscopic brush, the first seal 5 can significantly reduce the leakage risk of the enzyme solution during transmission, ensuring that the enzyme solution can be accurately and efficiently delivered to the brush head of the endoscopic brush. The enzyme solution usually has certain chemical properties and corrosiveness. If leakage occurs, it may cause damage to the endoscopic brush or the surrounding environment. The use of the first seal 5 improves the safety of use and protects the equipment and the environment.

[0039] In some embodiments of the present application, it further includes a second seal 6 disposed at one end of the movable sleeve 2 close to the tank body 1. The second seal 6 is used to reduce the gap between the tank body 1 and the movable sleeve 2 when the enzyme solution cartridge is in use.

[0040] The second seal 6 is disposed at one end of the movable sleeve 2 close to the tank body 1. Its main function is to reduce the gap between the tank body 1 and the movable sleeve 2 during use. Through physical contact and sealing action, it ensures that the enzyme solution in the tank body 1 remains in a sealed state without leakage.

[0041] Specifically, when the movable sleeve 2 is driven by the reset member 3 to be reset, the plugging member 4 closes the tank opening. At this time, the second seal 6 closely adheres between the movable sleeve 2 and the tank body 1, forming an additional sealing layer. This sealing layer can effectively prevent the enzyme solution from seeping out from the tiny gap between the tank body 1 and the movable sleeve 2. The second seal 6 significantly reduces the gap between the tank body 1 and the movable sleeve 2, thus effectively preventing the leakage problem of the enzyme solution during use. This ensures the purity and use efficiency of the enzyme solution.

[0042] It should be noted that both the first seal 5 and the second seal 6 are components provided to improve the sealing performance of the enzyme solution cartridge. The materials of the first seal 5 and the second seal 6 can be set according to requirements (including but not limited to): silicone rubber, nitrile rubber, thermoplastic elastomer, polyurethane, fluororubber or polytetrafluoroethylene.

[0043] In some embodiments of the present application, a limiting member 7 is further included. The limiting member 7 is disposed at the mouth of the tank body 1, between the movable sleeve 2 and the tank body 1, to block the movement of the movable sleeve 2 and keep the sealing member 4 in a closed state all the time. The limiting member 7 is installed at the mouth of the tank body 1 and is located between the movable sleeve 2 and the tank body 1. By mainly blocking the movement of the movable sleeve 2, it ensures that the sealing member 4 always remains in a closed state, thereby preventing the leakage of the enzyme solution.

[0044] Specifically, when the enzyme solution cartridge is not docked with the endoscopic brush, the limiting member 7 blocks the movable sleeve 2 from moving towards the tank body 1, ensuring that the sealing member 4 closely fits against the inner side of the mouth of the tank body 1 and keeping the mouth of the tank closed. In this case, the enzyme solution is safely stored in the tank body 1 without leakage. When it is necessary to dock the enzyme solution cartridge with the endoscopic brush, the limiting member 7 can be removed or a sufficient force can be applied to make the movable sleeve 2 overcome the resistance of the limiting member 7 to move, thereby achieving docking. After docking, the movable sleeve 2 is squeezed and moved, causing the sealing member 4 to separate from the mouth of the tank, thus opening the mouth of the tank and allowing the enzyme solution to flow out.

[0045] In some embodiments of the present application, such as Figure 4 and Figure 5 As shown, the limiting member 7 is of a ring structure. A through groove 71 is provided on one side of the inner wall of the limiting member 7 to form a disconnection portion, and a pull bar 72 is provided at a position on the outer wall of the limiting member 7 corresponding to the disconnection portion. Specifically, the limiting member 7 adopts a ring structure and is tightly sleeved on the mouth of the tank body 1. The through groove 71 on one side of its inner wall forms a disconnection portion, and the setting of the disconnection portion allows the limiting member 7 to break at a specific position by an external force. A pull bar 72 is provided at a position on the outer wall of the limiting member 7 corresponding to the disconnection portion. When the user needs to use the enzyme solution cartridge, only need to pull the pull bar 72 outwards; pulling the pull bar 72 will apply a pulling force to the disconnection portion, causing the disconnection portion to break. Once the disconnection portion breaks, the limiting member 7 is no longer a closed ring, and the limiting member 7 can be taken out, so it no longer has a blocking and limiting effect on the movable sleeve 2, and the movable sleeve 2 can move freely, thus realizing the convenient use of the enzyme solution cartridge.

[0046] During normal use, the limiting member 7 can effectively block the movement of the movable sleeve 2, ensuring that the sealing member 4 always maintains a closed state, thereby preventing accidental leakage of the enzyme solution and ensuring the safety of use. By simply pulling the pull bar 72, the limiting member 7 can be broken, and then the limiting member 7 can be easily disassembled and the enzyme solution cartridge can be used without additional complex tools or steps, significantly improving the convenience of removing the limit on the movable sleeve 2. Since the limiting member 7 is disposable and cannot be restored once broken, it is suitable for single-use enzyme solution cartridges.

[0047] In some embodiments of the present application, such as Figure 3As shown, the limiting member 7 is an elastic ring structure. The limiting member 7 is provided with an opening 73. The opening 73 allows the mouth of the tank body 1 to be inserted and located inside the limiting member 7, so that the limiting member 7 can prevent the movable sleeve 2 from moving towards the tank body 1. Specifically, the limiting member 7 adopts an elastic ring design, which enables it to deform when subjected to an external force and can return to its original state by its own resilience after the external force is removed. The opening 73 provided on the limiting member 7 allows the mouth of the tank body 1 to be inserted, and the mouth part can pass through the opening 73 and be located inside the limiting member 7. During the installation of the limiting member 7, first bend the limiting member 7 to expand the opening 73, and then align and insert the mouth of the tank; once the mouth of the tank passes through the opening 73, release the limiting member 7, and the limiting member 7 will return to its original state due to its resilience and tightly sleeve on the mouth of the tank, thus preventing the movable sleeve 2 from moving towards the tank body 1. By blocking the movement of the movable sleeve 2, the limiting member 7 ensures that the sealing member 4 always fits tightly against the inner side of the mouth of the tank, effectively preventing the enzyme solution from flowing out when not needed and ensuring good sealing performance. The automatic resilience and sleeving function of the limiting member 7 make the installation and disassembly process of the enzyme solution bomb more simple and fast. With such a structural design, the limiting member 7 can be recycled and is suitable for the reusable enzyme solution bomb.

[0048] It should be noted that the endoscopic brush includes a handle 81 and an upper cover 82. The handle 81 has a cavity 83 for accommodating the enzyme solution bomb. The communication port 84 is located at the bottom of the cavity 83. After the enzyme solution bomb is placed in the cavity 83, it is fixedly installed by covering and connecting the upper cover 82 and the handle 81. And during this process, since the upper cover 82 and the handle 81 are threadedly connected, when the upper cover 82 and the handle 81 are rotated and tightened, the enzyme solution bomb will be gradually squeezed, causing the movable sleeve 2 to move and the reset member 3 to deform. When the upper cover 82 and the handle 81 are completely tightened, the tank body 1 is successfully communicated with the communication port 84.

[0049] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present utility model.
