[0037] Please refer to the following: Figures 2 to 6 The leak-proof structure and catheter insertion simulation training device provided in the embodiments of this application will now be described.
[0038] The first aspect of this application is to provide a leak-proof structure and a catheter insertion simulation training device, including a tube body 10, a fixing frame 20, a first sealing valve 30, and a second sealing valve 40.
[0039] The tube body 10 has a liquid flow channel 11 inside. The fixing bracket 20 is installed in the liquid flow channel 11. The fixing bracket includes a first fixing ring 21 and a second fixing ring 22. The first fixing ring 21 and the second fixing ring 22 are spaced apart along the extension direction of the liquid flow channel 11. The first fixing ring 21 has a first through hole 211 and the second fixing ring 22 has a second through hole 221. The first through hole 211 and the second through hole 221 are coaxially arranged.
[0040] The outer walls of the first fixing ring 21 and the second fixing ring 22 abut against the inner wall of the liquid flow channel 11.
[0041] The second fixing ring 22 is located at one end of the liquid flow channel 11 near the bladder-simulated airbag 60 used for storing liquid.
[0042] The first sealing valve 30 is tubular and made of an elastic material, such as rubber. One end of the first sealing valve 30 is connected to the outside of the first through hole 211, and the other end is connected to the outside of the second through hole 221. The inner diameter of the first sealing valve 30 is smaller than the diameter of the target catheter 50.
[0043] The second sealing valve 40 is connected to the first through hole 211. The second sealing valve 40 has a cross-shaped slot 41 to form four diaphragms 42 on the second seal. The slot 41 penetrates the second sealing valve 40. The second sealing valve 40 is made of elastic material. When the target catheter 50 is inserted into the first through hole 211, the diaphragm 42 undergoes elastic deformation. When the target catheter 50 is pulled out of the first through hole 211, the diaphragm 42 resets to seal the first through hole 211, thereby preventing liquid leakage.
[0044] The diameter of the target conduit 50 is equal to the diameter of the second through hole 221. When the target conduit 50 is inserted into the first through hole 211 and the second through hole 221, the outer wall of the target conduit 50 abuts against the inner wall of the second through hole 221.
[0045] The second fixing ring 22 is provided with a third through hole 222, which is used to connect the parts located on both sides of the second fixing ring 22 in the liquid flow channel 11.
[0046] When the target catheter 50 is inserted into the first through hole 211 and the second through hole 221, the liquid in the bladder simulation balloon 60 enters the liquid flow channel 11 through the third through hole 222 at the location between the second fixing ring 22 and the first fixing ring 21. Under the action of liquid pressure and its own elasticity, the first sealing valve 30 abuts against the side wall of the target catheter 50 to prevent liquid leakage. When the target catheter 50 is separated from the fixation frame 20, the second sealing valve 40 closes the second through hole 221 to prevent liquid leakage.
[0047] Compared with the prior art, when the target conduit 50 is inserted into the first through hole 211 and the second through hole 221, the first sealing valve 30 abuts against the side wall of the target conduit 50 under the action of liquid pressure to prevent liquid leakage. When the target conduit 50 is separated from the fixing frame 20, the second sealing valve 40 is used to close the second through hole 221 to prevent liquid leakage.
[0048] In this application, the diameter of the first through hole 211 is larger than the diameter of the second through hole 221, so that the target conduit 50 can be inserted into the second through hole 221 in the direction from the first fixing ring 21 to the second fixing ring 22.
[0049] In this application, the mounting bracket 20 also includes a guide rod 23.
[0050] One end of the guide rod 23 is connected to the first fixing ring 21, and the other end is connected to the second fixing ring 22. The guide rod 23 is close to the side of the second fixing ring 22, and the inner wall of the guide rod 23 close to the second fixing ring 22 is flush with the inner wall of the second through hole 221.
[0051] There are multiple guide rods 23, and the multiple guide rods 23 are evenly spaced along the circumference of the fixed frame.
[0052] Preferably, there are two guide rods 23. By setting the guide rod 23 between the first fixing ring 21 and the second fixing ring 22, and setting the inner wall of the guide rod 23 on the side near the second fixing ring 22 flush with the inner wall of the second through hole 221, when the target conduit 50 is inserted into the second through hole 221 in the direction from the first fixing ring 21 to the second fixing ring 22, the guide rod 23 guides the target conduit 50 to be inserted into the second through hole 221.
[0053] In this application, there are multiple third through holes 222, and the multiple third through holes 222 are evenly spaced along the circumference of the second fixing ring 22.
[0054] Secondly, this application provides a catheter insertion simulation training device, including a dummy body (not shown in the figure), a bladder simulation balloon 60, and a leak-proof structure.
[0055] A bladder-simulating airbag 60 is installed inside the dummy at the location corresponding to the human bladder. The bladder-simulating airbag 60 is used to store liquid. The tube 10 in the leak-proof structure is connected to the bladder-simulating airbag 60 and communicates with its interior. The leak-proof structure is any of the leak-proof structures provided above.
[0056] The beneficial effects of the catheter insertion simulation training device provided in this application are as follows: Compared with the prior art, the catheter insertion simulation training device provided in this application includes the leak-proof structure provided by any of the above-mentioned components. The leak-proof structure includes a tube body 10, a fixing frame 20, a first sealing valve 30, and a second sealing valve 40. The tube body 10 has a liquid flow channel 11 inside, and the fixing frame 20 is installed in the liquid flow channel 11. The fixing frame includes a first fixing ring 21 and a second fixing ring 22. The first fixing ring 21 and the second fixing ring 22 are spaced apart along the extension direction of the liquid flow channel 11. The first fixing ring 21 has a first through hole 211, and the second fixing ring 22 has a second through hole 211. Two through holes 221, the first through hole 211 and the second through hole 221 are coaxially arranged, the first sealing valve 30 is tubular, and one end of the first sealing valve 30 is connected to the outside of the first through hole 211, and the other end is connected to the outside of the second through hole 221. The second sealing valve 40 is installed in the first through hole 211. When the target catheter 50 is inserted into the first through hole 211 and the second through hole 221, the first sealing valve 30 abuts against the side wall of the target catheter 50 under the action of liquid pressure to prevent liquid leakage. When the target catheter 50 is separated from the fixing frame 20, the second sealing valve 40 is used to close the second through hole 221 to prevent liquid leakage.
[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
