Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a simulated endoscope device. Background Technology

[0002] With the development of society and the advancement of medical technology, doctors need to learn how to use various new machines. Existing digestive endoscopes cannot be simulated during use, which increases the time and effort doctors need to learn and reduces work efficiency.

[0003] With the development of endoscope cleaning and disinfection technology, the requirements for endoscope cleaning and disinfection standards are becoming increasingly stringent. For example, the requirements and tests for chemically disinfected cleaning and disinfection devices for flexible endoscopes clearly state that the patency of the endoscope needs to be tested. However, few domestic devices can perform this function, mainly because there is a lack of equipment that can simulate the blockage of flexible endoscopes, making it impossible to verify the patency of the endoscope.

[0004] Traditional simulated endoscope structures are too simple to accurately simulate the blockages and connector detachment encountered by endoscopes during cleaning and disinfection. Moreover, it is difficult and extremely costly to simulate blockages in certain locations of a real endoscope. Therefore, domestic endoscope cleaning and disinfection machines are not designed and manufactured to perform endoscope cleaning and disinfection connector blockage and detachment monitoring tests. As a result, most cleaning and disinfection machines do not have this function, which is the biggest gap between domestic endoscope cleaning and disinfection machines and imported equipment.

[0005] Therefore, how to solve the problem that simulated endoscopes cannot simulate the tubing of real endoscopes is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The core of this invention is to provide a simulated endoscope device. By setting multiple detection points and simulating real structures such as endoscope handle plugs, it can completely simulate the tubing of a real endoscope, thereby enabling the monitoring of cleaning and disinfection and the detection of patency of the simulated endoscope.

[0057] Please refer to Figure 1 A simulated endoscope device includes an endoscope, which includes a front end tube 1, a middle end tube 4, a middle and rear end tube 108, and a rear end tube 10.

[0058] Specifically, the end of the front-end pipe 1 is equipped with a lens 2 to acquire images of the area to be inspected. The front-end pipe 1 is equipped with a three-channel detection component 3 to simulate contamination or blockage of the front section of the endoscope lumen. The middle section pipe 4 is connected to the front-end pipe 1. The middle section pipe 4 is equipped with a biopsy detection component 5, an air and water inlet detection component 6, and a first suction detection component 7. The biopsy detection component 5 is used to simulate contamination or blockage of the endoscope biopsy channel. The air and water inlet detection component 6 is used to simulate contamination or blockage of the middle section of the endoscope. The first suction detection component 7 is used to simulate contamination or blockage of the endoscope suction channel.

[0059] The mid-to-rear end pipe 108 is equipped with a handle simulation block 9 to simulate the handle of an endoscope. By setting the handle simulation block 9, the endoscope's cleaning and disinfection patency can be tested. The rear end pipe 10 is connected to the mid-to-rear end pipe 108. The rear end pipe 10 is equipped with an air inlet detection component 11, a water inlet detection component 12, and a second suction detection component 13. The air inlet detection component 11 is used to simulate the contamination or blockage of the endoscope's air inlet pipe. The water inlet detection component 12 is used to simulate the contamination or blockage of the endoscope's water inlet pipe. The second suction detection component 13 is used to simulate the contamination or blockage of the endoscope's suction pipe.

[0060] The simulated endoscope device set up in the above manner, by setting up multiple detection points and setting up realistic structures such as simulated endoscope handles, can completely simulate the tubing conditions of a real endoscope, so as to realize the cleaning and disinfection monitoring and patency testing of the simulated endoscope.

[0061] In the above embodiment, the front-end pipeline 1 includes a front-end suction pipe 1001, a front-end auxiliary water supply pipe 1002, and a front-end air and water inlet pipe 1003. One end of each of the front-end suction pipe 1001, the front-end auxiliary water supply pipe 1002, and the front-end air and water inlet pipe 1003 is connected to the lens 2. The other end of each of the front-end suction pipe 1001, the front-end auxiliary water supply pipe 1002, and the front-end air and water inlet pipe 1003 is connected to the three-channel detection component 3. The three-channel detection component 3 includes a three-channel detection box and a three-channel detection cover. The three-channel detection box is provided with three slots for placing contaminated tubes.

[0062] It should be noted that lens 2, front suction tube 1001, front auxiliary water supply tube 1002, and front air and water inlet tube 1003 simulate the internal tubing of the front lens 2 of a flexible endoscope. The three-channel detection box and the three-channel detection cover can be opened. The three-channel detection box has three slots for placing contaminated tubes. One contaminated tube with a diameter of 3mm and two with a diameter of 2mm are placed inside the three-channel detection box. The size of the slots is set to match the size of the contaminated tubes to simulate the contamination situation at the endoscope lens 2.

[0063] In this embodiment, the diameter of the front suction tube 1001 is 3mm, corresponding to a 3mm diameter bacterial contamination tube. The diameters of the front water supply tube 1002 and the front air and water inlet tube 1003 are 2mm, corresponding to a 2mm diameter bacterial contamination tube. However, in practical applications, the diameters of the front suction tube 1001, the front water supply tube 1002, and the front air and water inlet tube 1003 are not limited, as long as they are consistent with the diameter of the corresponding bacterial contamination tube.

[0064] In the above situation, the middle section pipeline 4 includes a middle section air inlet pipe 4001 and a middle section water inlet pipe 4002. One end of the middle section air inlet pipe 4001 and the middle section water inlet pipe 4002 is connected to the front air inlet and water inlet pipe 1003 through the water-air separation module 14. The other end of the middle section air inlet pipe 4001 and the middle section water inlet pipe 4002 is connected to the air inlet and water inlet detection component 6. The air inlet and water inlet detection component 6 includes an air inlet and water inlet detection box and an air inlet and water inlet detection cover. The air inlet and water inlet detection box is provided with two slots.

[0065] Understandably, by setting up the water-air separation module 14, the front air and water inlet pipe 1003 is divided into two sections: the middle air inlet pipe 4001 and the middle water inlet pipe 4002. The middle air inlet pipe 4001 and the middle water inlet pipe 4002 are connected to the air and water inlet detection component 6, which simulates the middle pipeline of the flexible endoscope. The air and water inlet detection component 6 is a dual-channel detection. Two bacterial tubes with a diameter of 2mm are placed inside the air and water inlet detection box to simulate the contamination situation in the middle of the endoscope.

[0066] In this embodiment, the diameters of the middle air inlet pipe 4001 and the middle water inlet pipe 4002 are both 2 mm, corresponding to the 2 mm diameter contamination tube. However, in practical applications, there are no restrictions on the diameters of the middle air inlet pipe 4001 and the middle water inlet pipe 4002, as long as they are consistent with the diameter of the corresponding contamination tube.

[0067] Furthermore, the biopsy detection component 5 is located on the first biopsy tube, which is connected to the front suction tube 1001 via a biopsy suction tee 15. The biopsy detection component 5 includes a biopsy detection box and a biopsy detection cover. One end of the biopsy detection box is provided with a biopsy connector 16, and a groove is provided on the biopsy detection box.

[0068] It should be noted that the biopsy aspiration tee 15 is connected to the front aspiration tube 1001. The biopsy aspiration tee 15 has one inlet and two outlets, with an included angle of 45 degrees between the two outlets. The biopsy detection component 5 connected to the biopsy connector 16 is a single-channel component. A 3mm diameter contaminated tube is placed inside the biopsy detection box to simulate the contamination of the biopsy connector 16.

[0069] In this embodiment, the included angle between the two outlets of the biopsy suction tee 15 is 45 degrees. However, in practical applications, there is no limitation on the included angle between the two outlets of the biopsy suction tee 15, as long as the above-mentioned technical effect can be achieved.

[0070] In the above embodiment, the first suction detection component 7 is disposed on the second biopsy tube 17, the second biopsy tube 17 is connected to the handle simulation block 9, and the first suction detection component 7 includes a first suction detection box and a first suction detection cover, and the first suction detection box is provided with a groove.

[0071] Understandably, the first suction detection component 7 simulates the central suction channel of a flexible endoscope. The first suction detection component 7 is a dual-channel detection device. A 3mm diameter contaminated tube is placed inside the first suction detection box to simulate the contamination situation in the central part of the endoscope suction channel, which is the contamination situation of the second biopsy tube 17.

[0072] Based on the above embodiments, the middle and rear end pipeline 108 includes a middle and rear water inlet pipe 8001 and a middle and rear air inlet pipe 8002 for connecting the air and water inlet detection box and the handle simulation block 9, and also includes a second biopsy tube 17 for connecting the handle simulation block 9 and the second suction detection component 13.

[0073] It should be noted that the connection between the handle simulation block 9 and the air / water inlet detection box is achieved by setting the middle and rear water inlet pipe 8001 and the middle and rear air inlet pipe 8002, and the connection between the handle simulation block 9 and the second suction detection component 13 is achieved by setting the second biopsy tube 17.

[0074] In the above embodiment, the rear pipeline 10 includes a rear air inlet pipe 101 and a rear water inlet pipe 102. The rear air inlet pipe 101 is used to connect the air inlet detection component 11 and the handle simulation block 9. The air inlet detection component 11 includes a rear air inlet detection box and a rear air inlet detection cover. The end of the rear air inlet pipe 101 is provided with an air inlet connector 18. The rear air inlet detection box is provided with a groove. The rear water inlet pipe 102 is used to connect the water inlet detection component 12 and the handle simulation block 9. The water inlet detection component 12 includes a water inlet detection box and a water inlet detection cover. The water inlet detection box is provided with two grooves.

[0075] Understandably, the air inlet detection component 11 is a single-channel device, with a 2mm diameter contaminated tube placed inside the air inlet detection box to simulate the contamination of the endoscope air inlet connector 18. The water inlet detection component 12 is a dual-channel device, with two 2mm diameter contaminated tubes placed inside the water inlet detection box to simulate the contamination of the endoscope water inlet connector.

[0076] In this embodiment, the diameters of the rear air inlet pipe 101 and the rear water inlet pipe 102 are both 2 mm to correspond to the 2 mm diameter contamination tube. However, in practical applications, there are no restrictions on the diameters of the rear air inlet pipe 101 and the rear water inlet pipe 102, as long as they are consistent with the diameter of the corresponding contamination tube.

[0077] Furthermore, the rear water inlet pipe 102 is connected to the water inlet pipe splitter 20 through the water inlet pipe connector 19. The water inlet pipe splitter 20 is connected to the water inlet end detection component 12 through the first water inlet pipe 21 and the second water inlet pipe 22. The end of the first water inlet pipe 21 is provided with a first water inlet connector 23, and the end of the second water inlet pipe 22 is provided with a second water inlet connector 24.

[0078] It should be noted that the water entering the water inlet pipe decomposer 20 has two sources. One part of the water enters the water inlet pipe decomposer 20 from the first water inlet pipe 21 through the first water inlet connector 23, and the other part of the water enters the water inlet pipe decomposer 20 from the second water inlet pipe 22 through the second water inlet connector 24. After passing through the water inlet pipe decomposer 20, it flows out from the rear water inlet pipe 102 to the handle simulation block 9.

[0079] In this embodiment, the water entering the inlet pipe decomposer 20 consists of two parts, but in practical applications, this is not a limitation.

[0080] In the above case, the second attraction detection component 13 includes a second attraction detection box and a second attraction detection cover. The second attraction detection box is provided with a groove, and one end of the second attraction detection box is provided with an attraction connector 25.

[0081] Understandably, the second suction detection component 13 is a single channel, and a 3mm diameter contaminated tube is placed inside the second suction detection box to simulate the contamination of the endoscope suction connector 25.

[0082] In this embodiment, the diameter of the groove of the second suction detection box is set to 3mm to accommodate the size of the second biopsy tube 17. In practical applications, there is no limitation on the diameter of the groove of the second suction detection box, as long as it corresponds to the size of the second biopsy tube 17.

[0083] In the above embodiment, the handle simulation block 9 includes a handle body 9001. The handle body 9001 is provided with an auxiliary water supply connector 9002, a biopsy button port 9003, and an air and water inlet button port 9004. The front auxiliary water supply pipe 1002 is connected to the auxiliary water supply connector 9002, the second biopsy tube 17 is connected to the biopsy button port 9003, and the middle air inlet pipe 4001 and the middle water inlet pipe 4002 are connected to the rear air inlet pipe 101 and the rear water inlet pipe 102 through the air and water inlet button port 9004.

[0084] It should be noted that the biopsy button port 9003 and the air / water inlet button port 9004 are used to simulate the connection of the endoscope irrigation plug. During simulated endoscope disinfection monitoring, a contaminated tube of the appropriate size is placed in each simulated test box. The entire simulated endoscope is then placed inside the disinfection machine for simulated disinfection. After disinfection, the contaminated tube is removed and cultured for microorganisms, thus achieving a realistic simulation of the disinfection effect on all parts of the endoscope. During simulated endoscope patency testing, a solid tube of the appropriate size is placed in the corresponding test box according to the monitoring requirements, causing a blockage in the entire pipeline at that location. The entire simulated endoscope is then placed inside the disinfection machine for disinfection. The test aims to determine whether the disinfection machine can identify the blockage in the simulated endoscope and, more specifically, which pipeline is blocked.

[0085] In summary, the simulated endoscope device provided by this invention can completely simulate the tubing of a real endoscope and set up detection points at multiple locations to simulate real structures such as endoscope handle plugs. It can simulate endoscope blockage, connector detachment, and the cleaning and disinfection effect of different parts of the endoscope, which can greatly improve the detection level of the cleaning and disinfection effect of endoscope cleaning and disinfection machines, thereby improving the quality of endoscope cleaning and disinfection in China. It can also completely replace the connected tubing to be compatible with the testing of all types of endoscopes.
