Description
Technical Field
[0001] This utility model relates to the technical field of medical devices, specifically to a sampling device for monitoring the disinfection effect of a flexible endoscope. Background Technology
[0002] As an interventional medical device, endoscopes come into direct contact with human tissues and mucous membranes. Therefore, they are disinfected after use to prevent cross-infection between different patients. The quality of disinfection directly affects human health and safety, making monitoring the disinfection effect of endoscopes crucial. Currently, the method for monitoring endoscope disinfection involves staff using an injection device to extract eluent after disinfection, then injecting the eluent back into the endoscope lumen, and finally collecting the sampled fluid discharged from the endoscope using a collector. However, this method is inconvenient and inefficient due to the dispersed nature of the equipment, requiring multiple operators. Furthermore, repeated manual operations can easily lead to contamination, affecting the monitoring results. Utility Model Content
[0003] The technical objective of this invention is to address the shortcomings of the prior art by providing a sampling device for monitoring the disinfection effect of flexible endoscopes that integrates the injector and collector, thereby reducing the risk of contamination.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A sampling device for monitoring the disinfection effect of a flexible endoscope, the sampling device having an injector and a collector connected together;
[0006] The injector has an injection chamber, the collector has a collection chamber, and the injection chamber and the collection chamber are connected.
[0007] The injector contains a piston assembly that separates the injector's injection chamber from the collector's collection chamber into independent storage spaces.
[0008] The injection chamber is used to store the eluent, and the injection chamber is detachably connected to the biopsy port of the endoscope. The eluent is injected into the endoscope during the movement of the piston assembly.
[0009] The collection chamber is used to store the sampling fluid. The collection chamber is detachably connected to the distal opening of the endoscope and collects the sampling fluid discharged from the endoscope during the movement of the piston assembly.
[0010] The aforementioned technical measures connect the injector and the collector together, using a piston assembly to divide the injection chamber of the injector and the collection chamber of the collector into independent storage spaces. This integration of the injector and collector ensures that the injection of eluent and the collection of sample solution are independent and do not interfere with each other, preventing the eluent from mixing with the sample solution and affecting the sample solution's concentration. The integration of the injector and collector simplifies the operation, allowing the injection of eluent and the collection of sample solution to be performed simultaneously, which improves efficiency and reduces manual operation, thus reducing the risk of contamination caused by external factors. The movement of the piston assembly injects eluent into the endoscope, and this movement creates a negative pressure in the collection chamber of the collector, allowing the sample solution discharged from the endoscope to flow into the collection chamber more quickly, further improving efficiency.
[0011] Furthermore, the portion of the injection chamber away from the collection chamber is sealed with an injection pipeline with a flexible hose structure.
[0012] The above-mentioned technical measures, by setting up a tubular injection pipeline, facilitate the connection between the injection chamber of the injector and the endoscope, which improves convenience and flexibility.
[0013] Furthermore, the end of the injection tubing away from the injection cavity has a flexible connector that matches the endoscope biopsy port.
[0014] The above-mentioned technical measures, by setting a flexible connector at the end of the injection tubing away from the injection cavity that matches the endoscope biopsy port, can make the connection between the injection tubing and the endoscope biopsy port tighter, which helps to prevent the elution fluid from overflowing; at the same time, the flexible connector can be adapted to different models of endoscopes, which helps to improve versatility.
[0015] Furthermore, a valve for controlling the on / off state of the injection pipeline is connected to the injection pipeline.
[0016] The above-mentioned technical measures, by connecting a valve to the injection pipeline to control the opening and closing of the injection pipeline, can control the opening and closing of the injection pipeline, which helps to prevent the leakage of the eluent and is simple to operate.
[0017] Furthermore, the liquid collector has a sealing cap and a collection cylinder that are detachably and sealingly connected at the upper and lower positions;
[0018] The top of the sealing cap has an integrally formed, detachable, and sealingly connected injection connector to the injection chamber.
[0019] The top of the sealing cap also has an integrally formed, detachable, and sealingly connected collection connector for the distal opening of the endoscope.
[0020] Both the injection connector and the collection connector are connected to the collection chamber of the liquid collector.
[0021] In the above-mentioned technical measures, the top of the sealing cap has an integrally formed, detachable sealing connection to the injection chamber, and the injection connector is connected to the collection chamber, which facilitates the connection and disassembly of the injector and the collector, and at the same time helps to ensure the sealing of the connection. The top of the sealing cap also has an integrally formed, detachable sealing connection to the distal opening of the endoscope, which facilitates the connection and disassembly of the collector and the endoscope, and at the same time helps to ensure the sealing of the connection.
[0022] Furthermore, the collection connector is detachably and sealedly connected to a collection hose, the top end of which is flared outwards, and the length of the collection hose is greater than the arrangement distance between the collection connector and the injection connector.
[0023] The collection tubing has a funnel-shaped opening with a flexible fitting ring that matches the distal opening of the endoscope, and a flexible fitting ring that matches the injection connector.
[0024] The aforementioned technical measures include a detachable and sealed connection between the collection tubing and the collection connector, which helps to prevent leakage of the sampling liquid and contamination of the sampling liquid due to external factors. The top of the collection tubing is shaped like an outward-expanding trumpet, and the trumpet-shaped opening of the collection tubing has a flexible fitting ring that matches the distal opening of the endoscope, which helps to ensure a tight seal between the collection tubing and the distal opening of the endoscope, ensuring that the sampling liquid flows smoothly into the collection chamber. At the same time, it facilitates the disassembly and assembly of the collection tubing and the distal opening of the endoscope. The length of the collection tubing is greater than the arrangement distance between the collection connector and the injection connector, and the trumpet-shaped opening of the collection tubing has a flexible fitting ring that matches the injection connector. After the sampling liquid is collected, the injection device can be removed, which allows the collection tubing and the injection connector to be tightly sealed, ensuring sealing performance and helping to prevent contamination of the sampling liquid. It also facilitates the disassembly and assembly of the collection tubing and the injection connector.
[0025] Furthermore, the injection chamber has a connector that is sealed to the injection joint, and the connector of the injection chamber has a flexible fitting ring that matches the injection joint.
[0026] In the above technical measures, the injection chamber has a connector that is sealed to the injection joint. The connector of the injection chamber has a flexible fitting ring that matches the injection joint, which ensures the sealing performance of the connection between the injection joint and the connector while facilitating disassembly and assembly.

[0028] The liquid collecting chamber of the liquid collector has a hollowed-out sieve frame, and the sieve frame is arranged at a height interval with the bottom of the liquid collecting chamber;
[0029] The sieve frame is covered with a filter membrane.
[0030] The above-mentioned technical measures, by setting a perforated sieve frame in the liquid collection chamber, can effectively support the filter membrane while allowing the filtered sample liquid to flow through the sieve frame to the bottom of the liquid collection chamber. The sieve frame and the bottom of the liquid collection chamber are arranged at a height interval, and the sample liquid filtered by the filter membrane can be discharged through the drain port, so that all the sample liquid is filtered by the filter membrane, thereby efficiently intercepting microorganisms in the sample liquid and improving the accuracy of detection.
[0031] Furthermore, the screen frame has a funnel-shaped structure with high edges and a low center.
[0032] In the above-mentioned technical measures, the sieve frame is a funnel-shaped structure with high edges and low center, which can guide the sampling liquid to flow towards the central area of the filter membrane. This helps to concentrate the microorganisms intercepted on the filter membrane in the central area of the filter membrane after filtration, which is convenient for subsequent detection operations.
[0033] Furthermore, the piston assembly has a piston body, a piston rod, and a piston handle connected in sequence;
[0034] The piston body is assembled in the injection chamber with a sealed structure;
[0035] The piston rod passes through the end of the injection chamber away from the collection chamber in a sealed structure;
[0036] The piston handle is located outside the injection chamber.
[0037] The piston assembly described above has a piston body, piston rod, and piston handle connected in sequence, which is simple in structure and easy to operate. The piston body is assembled in the injection chamber with a sealed structure, and the piston rod passes through the injection chamber at the end away from the collection chamber with a sealed structure, which helps to avoid leakage of the eluent.

[0051] The collection chamber is used to store the sampling liquid. The collection chamber is detachably connected to the distal opening of the endoscope 4 and collects the sampling liquid discharged from the endoscope 4 during the movement of the piston assembly 3.
[0052] The piston assembly 3 has a piston body 31, a piston rod 32 and a piston handle 33 connected in sequence;
[0053] Piston body 31 is assembled in the injection chamber with a sealed structure;
[0054] The piston rod 32 passes through the end of the injection chamber away from the collection chamber in a sealed structure;
[0055] The piston handle 33 is located outside the injection chamber.
[0056] The injection chamber is located away from the collection chamber, and a sealing connection is made to the injection pipeline 5, which has a flexible hose structure.
[0057] The end of the injection tubing 5 away from the injection cavity has a flexible connector 6 that matches the biopsy port of the endoscope 4.
[0058] A valve 7 is connected to the injection line 5 to control the opening and closing of the injection line 5.
[0059] Among them, valve 7 can be a Robert clamp.
[0060] The liquid collector 2 has a sealing cover 21 and a collection cylinder 22 that are detachably and sealingly connected at the top and bottom. The sealing cover 21 and the collection cylinder 22 can be connected by threads and corresponding sealing rings to achieve a detachable and sealing connection between the sealing cover 21 and the collection cylinder 22. Alternatively, a flexible fitting ring matching the collection cylinder 22 can be provided on the inner wall of the sealing cover 21 to achieve a detachable and sealing connection between the sealing cover 21 and the collection cylinder 22.
[0061] The top of the sealing cap 21 has an integrally formed, detachable, and sealingly connected injection connector 8 to the injection chamber;
[0062] The top of the sealing cap 21 also has an integrally formed, detachable sealing connection to the distal opening of the endoscope 4 collection connector 9;
[0063] Both the injection connector 8 and the collection connector 9 are connected to the collection chamber of the liquid collector 2.
[0064] The collection connector 9 is detachably and sealedly connected to a collection hose 10. The top end of the collection hose 10 is flared outwards, and the length of the collection hose 10 is greater than the arrangement distance between the collection connector 9 and the injection connector 8.
[0065] The collection tubing 10 has a flared opening with a flexible fitting ring that matches the distal opening of the endoscope 4, and a flexible fitting ring that matches the injection connector 8.
[0066] The collection tubing 10 has multiple flexible fitting rings of different sizes inside its flared opening, which are used to match the distal openings of different endoscopes 4, thus improving flexibility and versatility of the collection tubing 10.
[0067] The injection chamber has a connector 11 that is sealed to the injection connector 8, and the connector 11 of the injection chamber has a flexible fitting ring that matches the injection connector 8.
[0068] The liquid collector 2 has a drain port at the bottom of its collection chamber, and a removable plug 12 is sealed to the drain port.
[0069] In order to prevent the sampling device from tipping over when it is upright, multiple support bases are provided at the bottom of the liquid collector 2. The height of the support bases is greater than or equal to the length of the plug 12 extending out of the liquid collector 2. The number of support bases depends on actual needs and is not specifically limited in this embodiment.
[0070] The liquid collector 2 has a hollowed-out sieve frame 14 in the liquid collection chamber. The sieve frame 14 is arranged at a height interval with the bottom of the liquid collection chamber. The position of the sieve frame 14 is at 1 / 5 of the height of the liquid collection chamber, which helps to prevent the liquid storage space above the filter membrane 13 in the liquid collection chamber from being quickly filled due to the excessive flow rate of the sampling liquid. The position of the sieve frame 14 can be adjusted according to actual needs.
[0071] A filter membrane 13 is laid on the sieve frame 14; the sieve frame 14 has a funnel-shaped structure with high edges and low center.

The number of protrusions depends on the actual needs, and this embodiment does not make a specific limitation.
[0074] In this embodiment, the sampling device is sealed in a sterile packaging bag when not in use.
[0075] In application, unpack the sterile packaging bag, remove the sampling device, connect the flexible connector 6 of the injection line 5 to the biopsy port of the endoscope 4, open the valve 7, and then connect the distal opening of the endoscope 4 to the collection tubing 10. Pull the piston handle 33 upward, which will move the piston rod 32 upward, thereby moving the piston body 31 upward. This will push the eluent in the injection chamber into the endoscope 4 through the injection line 5. As the piston body 31 moves upward, a negative pressure is formed in the collection chamber. The eluent mixes thoroughly with microorganisms in the endoscope 4 to form a sampling solution. The sampling solution flows out from the distal opening of the endoscope 4 and into the collection chamber through the collection tubing 10. After collection, remove the injector 1, connect the collection tubing 10 to the injection connector 8, and complete the sealing operation. The collector 2 can then be sent for testing.
[0076] After receiving the liquid collector 2, the monitoring staff placed it on the shaking device and shook it. After shaking, they removed the plug 12, placed the liquid collector 2 on the extraction device, and extracted the sampled liquid until all the sampled liquid had been filtered through the filter membrane 13. Then, they removed the sealing cap 21 of the liquid collector 2, took out the filter membrane 13, and proceeded with subsequent monitoring.
[0077] The aforementioned shaking device and liquid extraction device are both commonly used conventional devices.
