Description

Technical Field

[0001] This utility model relates to the field of endoscopic culture device technology, specifically an integrated endoscopic culture anti-contamination device with infusion delivery function. Background Technology

[0002] As an important medical device for clinical diagnosis and treatment, the cleaning, disinfection, and microbial culture monitoring of endoscopes after use are crucial steps in preventing cross-infection and ensuring medical safety.

[0003] Current endoscopic culture devices lack an integrated infusion delivery structure. When culture medium needs to be replenished or replaced during the culture process, medical staff must manually perform the operation using a syringe: first, open the device's cap (or sealed port), then insert the syringe needle into the culture chamber to inject the culture medium. After each injection, the needle must be removed and the cap closed. If multiple replenishments of culture medium are required during the culture cycle, the above "open cap-inject-close cap" process must be repeated. This operation method is not only time-consuming and labor-intensive, but also significantly increases the workload of medical staff, reduces overall testing efficiency, and is difficult to adapt to the high-frequency, fast-paced monitoring needs of clinical practice, especially when processing multiple sets of endoscopic culture samples in batches. Furthermore, it can easily lead to distorted test results and mislead clinical judgment of the endoscope's cleaning effect, increasing the risk of cross-infection.

[0004] Therefore, this invention provides an integrated endoscopic culture anti-contamination device with infusion delivery function to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides an integrated endoscopic culture anti-contamination device with infusion delivery function, such as... Figure 1 — Figure 5 As shown, the device includes a base 1, with multiple sets of culture tubes 2 connected to the top of the base 1. Each set of culture tubes 2 has a guide tube 5 connected to its outer surface, and the end of the guide tube 5 is connected to a delivery tube 51. The bottom of each set of culture tubes 2 is connected to a diversion tube 53. The guide tube 5 and the delivery tube 51 work together to achieve centralized delivery of culture medium, eliminating the need for manual injection of each set and solving the efficiency problem of repeated opening and injection in traditional devices. The end of the diversion tube 53 is connected to a drain tube 52, and the diversion tube 53 and the drain tube 52 form a unified waste liquid discharge channel, preventing the waste liquid from being dumped at will and polluting the environment. The top of the multiple sets of culture tubes 2 is equipped with a protective component, which is used to seal and protect the culture dishes inside the multiple sets of culture tubes 2.

[0024] The protective component includes a protective cover 3 that slides on multiple sets of culture tubes 2. Two sets of connecting rods 81 are fixedly installed on the inner wall of the protective cover 3. Placement plates 8 are fixedly installed at the ends of the two sets of connecting rods 81. The top of the placement plate 8 has a circular groove that matches the outer diameter of the culture dish, which is used to stably place the culture dish and prevent the culture dish from shifting or tipping over when the culture medium is transported or when there is slight vibration. This ensures that the endoscopic sample is always in the center of the culture dish and is in full contact with the culture medium, thereby improving the uniformity of the culture.

[0025] The protective cover 3 has multiple sets of magnetic pin grooves 7 at its bottom. Each set of culture tubes 2 has a limiting ring 4 fixedly installed on its outer surface, and each limiting ring 4 has multiple sets of magnetic pins 41 fixedly installed on its top. The multiple sets of magnetic pins 41 and the multiple sets of magnetic pin grooves 7 are magnetically attracted and locked together to achieve rapid positioning and sealing of the protective cover 3 and the culture tubes 2, blocking the flow of outside air to the inside of the culture tubes 2, effectively preventing the invasion of microorganisms such as airborne bacteria, and solving the pollution problem caused by poor sealing of traditional devices. At the same time, the magnetic attraction force is moderate, which not only ensures the sealing stability, but also makes it easy for medical staff to open the protective cover 3 with the handle 31, thus balancing the sealing effect and the ease of operation.

[0026] Among them, the inner walls of multiple culture tubes 2 are fixedly installed with support mesh plates 9. The support mesh plates 9 are made of stainless steel. The support mesh plates 9 can provide bottom support for the placement plate 8 and the culture dish, avoid the culture dish directly contacting the bottom of the culture tube 2, and prevent the culture dish from being deformed or damaged due to uneven force at the bottom. The mesh structure of the support mesh plates 9 allows the culture medium and waste liquid to flow freely, without affecting the replenishment of culture medium and the discharge of waste liquid.

[0027] Each of the protective covers 3 has an observation window 32 at its top. The observation window 32 allows medical staff to observe the clarity of the culture medium in the culture tube 2, the growth of bacterial colonies in the endoscopic sample, and the position of the culture dish in real time without opening the protective cover 3. Each of the protective covers 3 has a handle 31 fixedly installed on its outer surface. The handle 31 provides a convenient gripping point for medical staff to easily lift or press the protective cover 3 to open or close it.

[0028] Among them, the outer surface of the diversion tube 53 is equipped with an electronic valve 6, which is electrically connected to an external controller and is used to independently control the waste liquid discharge of each group of culture tubes 2. The timing of the discharge can be flexibly adjusted according to the culture progress of different culture tubes 2 to avoid cross-contamination or waste liquid backflow caused by the simultaneous discharge of multiple groups of culture tubes 2.

[0029] Working principle: First, the device is adjusted and the sample is placed before culture: Medical staff hold the handle 31 on the outer surface of the protective cover 3 and pull the protective cover 3 upwards, so that the protective cover 3 slides along the axis of the culture tube 2 until the top opening is fully exposed. Then, the culture dish containing the endoscope sample is placed steadily into the circular groove at the top of the placement plate 8. This prevents the culture dish from shifting or tipping over during subsequent operations, ensuring that the endoscope sample is always in the center of the culture dish, facilitating full contact with the culture medium.

[0030] After placing the culture dish, press down on handle 31 to allow the protective cover 3 to slide vertically down along the culture tube 2 until the placement plate 8 enters the culture tube 2 simultaneously with the protective cover 3, and the bottom of the protective cover 3 is in contact with the limiting ring 4 on the outer surface of the culture tube 2. At this point, the multiple sets of magnetic pins 41 at the top of the limiting ring 4 and the multiple sets of magnetic pin grooves 7 at the bottom of the protective cover 3 automatically align and engage with each other through magnetic adsorption, achieving rapid positioning of the protective cover 3 and the culture tube 2. This ensures accurate sealing without repeated adjustments, blocking the flow path between outside air and the inside of the culture tube 2, and preventing airborne bacteria. After microorganisms invade, the input end of the delivery tube 51 is connected to the external culture medium storage tank. At the same time, an infusion pump is connected to the delivery tube 51. After the infusion pump is started, the culture medium flows along the delivery tube 51 under the pressure of the pump body. Then, through the connection structure between the delivery tube 51 and multiple sets of guide tubes 5, it is evenly distributed to the guide tubes 5 corresponding to each set of culture tubes 2. Since the guide tubes 5 are connected to the outer surface of the culture tube 2 near the top, the culture medium can flow smoothly into the interior of the culture tube 2 along the guide tubes 5, avoiding direct impact on the endoscope sample in the culture dish and reducing sample disturbance.

[0031] When the culture medium flows into the culture tube 2, it first contacts the culture dish on the placement plate 8. Once the culture medium in the culture dish reaches the preset level, the excess culture medium will overflow from the edge of the culture dish, then flow downwards and contact the support mesh plate 9 on the inner wall of the culture tube 2. The mesh structure of the support mesh plate 9 also allows the overflowing culture medium to pass through smoothly and flow to the diversion tube 53 at the bottom of the culture tube 2.

[0032] When the culture cycle ends or the culture medium needs to be replaced, an external controller sends a command to the electronic valve 6 on the outer surface of the diversion tube 53, driving the electronic valve 6 to open (the electronic valve 6 is in a closed state during the culture stage to ensure that the culture medium remains in the culture tube 2). At this time, the waste culture medium in the culture tube 2 will flow along the diversion tube 53 to the converging drain tube 52 under the action of gravity, and finally be discharged into the external waste liquid collection device through the output end of the drain tube 52.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
