Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and specifically relates to a disinfection device for a soft bag infusion valve. Background Technology

[0002] In the field of medical infusion, soft bag infusion valves require strict sterilization before use. A common sterilization method involves pre-inserting a sponge soaked in disinfectant inside a sterilization cap, sealing it, tearing off the protective film, inserting the soft bag infusion valve into the cap, and rotating it to achieve sterilization. However, this sterilization cap has significant drawbacks.

[0003] During storage and transportation, the disinfection cap is often placed on its side or upside down. In this situation, due to gravity, the disinfectant solution tends to accumulate in the lower-lying sponge area, while the higher-lying areas (especially the critical area directly covering the infusion port, where the disinfectant solution is most needed) become relatively dry due to liquid loss. This directly leads to uneven distribution of the disinfectant solution within the sponge and an imbalance in the concentration of effective disinfectant components. During use, if the puncture needle happens to contact a dry area, sufficient disinfection cannot be achieved, and the lack of a structure for replenishing the disinfectant solution significantly increases the risk of infection due to incomplete disinfection and microbial invasion. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a soft bag infusion valve disinfection device, which solves the problem that existing disinfection caps lack a structure for replenishing disinfection solution, resulting in poor disinfection effects.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sterilization device for a soft bag infusion valve, comprising: A housing having an opening and an internal mounting cavity communicating with the outside through the opening, the opening being covered by a sealing film, and a hollow handle being disposed on the side of the housing opposite to the opening, the hollow handle communicating with the mounting cavity through a clearance hole; and, A disinfectant sponge is installed in the mounting cavity. The disinfectant sponge has a first disinfection part for contacting the top of the disinfectant soft bag infusion valve and a second disinfection part for contacting the periphery of the disinfectant soft bag infusion valve. The contact surfaces of the first and second disinfection parts with the soft bag infusion valve are provided with textured surfaces. A reservoir is provided between the first disinfection part and the cavity wall of the mounting cavity. The hollow handle is provided with a spiked component corresponding to the liquid reservoir. The spiked component is partially inserted at the end of the hollow handle away from the outer shell. The end of the spiked component facing the liquid reservoir has a spiked part. The spiked part is slidably arranged along the length of the hollow handle so as to be able to approach or move away from the liquid reservoir. When it approaches, it is used to puncture the liquid reservoir, releasing the disinfectant solution, which is then absorbed by the disinfectant sponge.

[0006] Preferably, the top surface of the first disinfection section is recessed to form a groove for installing the liquid reservoir, and the spike assembly is located at the open end of the outer shell facing the groove.

[0007] Preferably, the spike assembly further includes a movable rod and a spring. One end of the movable rod is provided with the spike portion, and the other end is provided with a limiting protrusion ring on its periphery and passes through the hollow handle. The spike portion faces the liquid storage bladder. The spring is sleeved on the periphery of the movable rod and is located between the spike portion and the limiting protrusion ring. One end of the spring abuts against one end of the limiting protrusion ring, and the other end abuts against the surface of the outer shell where the clearance hole is opened.

[0008] Preferably, the outer shell is provided with a plurality of limiting posts corresponding to the spring, and the limiting posts are distributed in a circumferential array around the clearance hole.

[0009] Preferably, the size of the clearance hole is smaller than the size of the liquid reservoir.

[0010] Preferably, the hollow handle has anti-slip texture on its periphery.

[0011] Preferably, the hollow handle has a protective cap threadedly connected to one end through which the spike assembly passes.

[0012] Preferably, the second disinfection section is stepped and conforms to the outer curve of the soft bag infusion valve.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This soft bag infusion valve disinfection device features an internal reservoir and a spike assembly to puncture it. This allows for the replenishment of disinfectant solution to the disinfecting sponge during surface disinfection of the soft bag infusion valve. This ensures sufficient solution in the primary disinfection area to effectively disinfect key areas such as the rubber cap of the valve, improving disinfection efficiency. Furthermore, the textured surface of both the disinfecting sponge and the soft bag infusion bag allows for more effective disruption and removal of pathogenic microbial biofilms during rotational disinfection, resulting in stronger physical cleaning. It also offers a large disinfection area and is easy to operate. Attached Figure Description

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 This utility model provides a disinfection device for a soft bag infusion valve, including a housing 1 and a disinfecting sponge 2. The housing 1 has an opening 11 and an internal mounting cavity 12 that communicates with the outside through the opening 11. The opening 11 is covered with a sealing film 3. A hollow handle 13 is provided on the side of the housing 1 opposite to the opening 11. The hollow handle 13 communicates with the mounting cavity 12 through a clearance hole 14. The disinfecting sponge 2 is installed in the mounting cavity 12. The disinfecting sponge 2 has a first disinfecting part 21 for contacting the top of the disinfecting soft bag infusion valve and a second disinfecting part 22 for contacting the periphery of the disinfecting soft bag infusion valve. The first disinfecting part 21 and the second disinfecting part 22 are in contact with the soft bag infusion valve. The surface is provided with a textured surface 23. A liquid storage bladder 4 is provided between the first disinfection part 21 and the cavity wall of the mounting cavity 12. A spike component 5 is provided inside the hollow handle 13 corresponding to the liquid storage bladder 4. The spike component 5 is partially inserted at the end of the hollow handle 13 away from the outer shell 1. The end of the spike component 5 facing the liquid storage bladder 4 is provided with a spike 51. The spike 51 is slidably arranged along the length of the hollow handle 13 so as to be able to approach or move away from the liquid storage bladder 4. When approaching, it is used to puncture the liquid storage bladder 4, releasing the disinfection solution and being absorbed by the disinfection sponge 2.

[0021] like Figure 1 and Figure 2 As shown, the outer shell 1 has the aforementioned clearance hole 14. The outer shell 1 and the hollow handle 13 can be aligned and installed by setting positioning posts and positioning grooves on the surfaces of the two that come into contact with each other, so that the open end of the hollow handle 13 corresponds to the clearance hole 14. The hollow handle 13 and the outer shell 1 can be connected by heat fusion, which has high connection strength and makes it easy for medical staff to drive the outer shell 1 to rotate through the hollow handle 13, thereby achieving all-round disinfection of the surface of the soft bag infusion valve.

[0022] In optional embodiments, such as Figure 1 and Figure 2As shown, a groove 211 is formed on the top surface of the first disinfection section 21. The groove 211 is used to install the reservoir 4, and the spike assembly 5 is located at the open end of the outer shell 1 facing the groove 211. The structure of the groove 211 ensures that the reservoir 4 can be accurately placed in the predetermined position and will not shift due to shaking or tilting during use. This ensures that the spike assembly 5 can accurately pierce the reservoir 4, avoiding piercing failure due to misalignment. Furthermore, it ensures that after the reservoir 4 is pierced, the disinfectant can slowly penetrate from the first disinfection section 21 to the second disinfection section 22, so that the amount of disinfectant solution in the first disinfection section 21 is always greater than that in the second disinfection section 22. This allows the first disinfection section 21 to disinfect the recessed part of the rubber stopper (i.e., the insertion area of ​​the infusion set), improving its disinfection effect on that area.

[0023] In optional embodiments, such as Figure 1 and Figure 2 As shown, the spike assembly 5 also includes a movable rod 52 and a spring 53. One end of the movable rod 52 is provided with the spike portion 51, and the other end has a limiting protrusion ring 521 on its periphery, passing through the hollow handle 13. The spike portion 51 faces the reservoir 4. The spring 53 is sleeved on the periphery of the movable rod 52 and located between the spike portion 51 and the limiting protrusion ring 521. One end of the spring 53 abuts against one end of the limiting protrusion ring 521, and the other end abuts against the surface of the outer shell 1 where the clearance hole 14 is provided. The movable rod 52, the limiting protrusion ring 521, and the spike portion 51 are integrally molded structures made of hard plastic, which is lightweight, ensuring the overall weight of the infusion valve sterilization structure is light, making it easy to carry and use.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, to prevent the spike assembly 5 from shifting, the outer shell 1 is provided with multiple limiting posts 131 corresponding to the spring 53. These limiting posts 131 are arranged in a circumferential array around the clearance hole 14. Specifically, the spring 53 is sleeved around the limiting posts 131 to support the spring 53 and guide the movable rod 52. The limiting posts 131 are positioned around the movable rod 52 to avoid obstructing its movement. The hollow handle 13's internal channel provides direction for the movement of the spike assembly 5 and, together with the spring 53 and limiting posts 131, ensures that the spike assembly 5 does not deviate or jam during movement, thus acting on the reservoir 4.

[0025] During installation, the spring 53 is mounted on the outer shell 1 through the limiting post 131. The spring 53 naturally extends and is sleeved between the limiting protrusion 521 and the spike 51 on the movable rod 52. The surface of the limiting protrusion 521 facing away from the spike 51 abuts against the inner top wall of the hollow handle 13. The end of the movable rod 52 passes through the hollow handle 13, and the other end of the spring 53 is sleeved on the limiting post 131 and abuts against the inner bottom wall of the hollow handle 13.

[0026] In an optional embodiment, the size of the clearance hole 14 is smaller than the size of the reservoir 4. Specifically, the length of the reservoir 4 is greater than the diameter of the clearance hole 14, to prevent the reservoir 4 from falling out of the groove 211 and into the hollow handle 13 when the soft bag infusion valve sterilization device is shaken by external force; alternatively, when the reservoir 4 is punctured, the soft bag infusion valve is inserted into the sterilizing sponge 2 and the sterilizing sponge 2 is squeezed, and the reservoir 4 is also squeezed at this time under the cooperation of the sterilizing sponge 2 and the hollow handle 13, so that the sterilizing solution in the reservoir 4 is released as much as possible.

[0027] In optional embodiments, such as Figure 3 As shown, the hollow handle 13 has anti-slip texture 132 on its periphery. This anti-slip design increases the effective contact area between the fingers and the handle 13, increasing friction. This allows medical personnel to easily and accurately control the rotation of the soft bag infusion valve sterilization device, ensuring a reliable and effective sterilization process. Furthermore, to prevent accidental activation of the movable lever 52 during transportation, a protective cap 133 is threaded onto the end of the hollow handle 13 through which the spike assembly 5 passes.

[0028] In optional embodiments, such as Figure 1 and Figure 2 As shown, the second disinfection section 22 is stepped and conforms to the outer curve of the soft bag infusion valve. The curved design of the second disinfection section 22 ensures its contact with the surface of the soft bag infusion valve for large-area disinfection. Simultaneously, the surfaces of the first disinfection section 21 and the second disinfection section 22 have a textured surface 23, such as wave patterns, raised dot matrices, grid patterns, radial sawtooth patterns, etc. Figure 4 In the illustrated embodiment, the first disinfection section 21 adopts a wavy texture, which increases its actual contact area with the complex curved surface of the soft bag infusion valve, especially the concave part of the rubber stopper. The second disinfection section 22 adopts a convex dot matrix. The two work together to enable the disinfectant to be coated onto all surfaces of the soft bag infusion valve more quickly and evenly, without dead corners. The further textured surface will have micro- and multi-directional relative friction with the connector surface of the soft bag infusion valve, which can more effectively destroy and remove the biofilm of pathogenic microorganisms, resulting in a stronger physical cleaning effect.

[0029] In this embodiment, the disinfectant solution is 75% medical alcohol, and the outer shell 1, hollow handle 13, spike component 5, and reservoir 4 membrane are all made of alcohol-resistant materials such as polypropylene and high-density polyethylene.

[0030] After the spike assembly 5 is positioned and installed on the housing 1 by the limiting post 131, the hollow handle 13 is sleeved on its periphery and the two are connected to each other by a hot-melt process, so that the spike part 51 corresponds to the relief hole 14 of the housing 1. Then, the disinfectant sponge 2 with the liquid storage bladder 4 is placed into the installation cavity 12 that is consistent with the shape of the disinfectant sponge 2, and the disinfectant sponge 2 is soaked by soaking. Then, the opening 11 of the housing 1 is sealed with a sealing film 3, and one end of the hollow handle 13 is protected with a protective cap 133. In use, remove the protective cover 133 and press the part through which the movable rod 52 passes. The movable rod 52 moves towards the reservoir 4. At this time, the spring 53 is compressed, and the spike 51 punctures the reservoir 4, releasing the disinfectant solution stored inside, which is then absorbed by the disinfectant sponge 2. After releasing the finger that pressed the movable rod 52, the spring 53 rebounds, causing the movable rod 52 to move away from the reservoir 4. Then, remove the sealing film 3 from the opening 11 of the outer shell 1, exposing the disinfection chamber with the disinfectant sponge 2. Insert the soft bag infusion valve to be disinfected into the disinfection chamber, which also squeezes the reservoir 4, accelerating the release of the disinfectant solution. Medical staff use their fingers to pinch the hollow handle 13, causing the soft bag infusion valve disinfection device to rotate and rub and disinfect the surface of the soft bag infusion valve. During the disinfection process, the disinfectant solution in the reservoir 4 slowly penetrates from the first disinfection section 21 to the second disinfection section 22, strengthening the disinfection of key areas such as the rubber cap of the soft bag infusion valve.

[0031] In summary, this soft bag infusion valve disinfection device has a reservoir 4 and a spike component 5 for puncturing the reservoir 4 inside. This allows for the replenishment of disinfectant solution to the disinfectant sponge 2 when disinfecting the surface of the soft bag infusion valve. This ensures that the first disinfection area has sufficient disinfectant solution to disinfect key areas such as the rubber cap of the soft bag infusion valve, improving the disinfection effect in that area. At the same time, the surface of the disinfectant sponge 2 and the soft bag infusion bag are textured with an uneven texture 23, which can more effectively destroy and remove the biofilm of pathogenic microorganisms during the rotation disinfection process, resulting in a stronger physical cleaning effect. It also has a large disinfection area and is easy to operate.
