[0033] Please refer to the following: Figures 1 to 6 The leakage-proof catheter insertion simulation training device provided in the embodiments of this application will now be described.

[0034] A leakage-proof catheter insertion simulation training device includes a dummy body 10, an airbag 20, a tube body 30, a sealing structure 40, and a sealing diaphragm 50.

[0035] An air bladder 20 is installed inside the dummy body 10 and located at the position corresponding to the bladder. The air bladder 20 is used to store liquid to simulate the bladder.

[0036] The tube body 30 is connected to the air bladder 20, and a liquid flow channel 31 is formed inside the tube body 30. Liquid flows from the air bladder 20 into the liquid flow channel 31 inside the tube body 30.

[0037] A sealing structure 40 is installed within the liquid flow channel 31, and the outer wall of the sealing structure 40 abuts against the inner wall of the liquid flow channel 31. The sealing structure 40 has a first end S1 and a second end S2, with the first end S1 located within the liquid flow channel 31 near the airbag 20. The sealing structure 40 includes an elastic sealing tube 41 and an elastic strip 42. One end of the elastic sealing tube 41 is fixedly connected to the first end S1, and the other end of the elastic sealing tube 41 is connected to the elastic strip 42. The end of the elastic strip 42 away from the elastic sealing tube 41 is fixedly connected to the second end S2. The orifice of the elastic sealing tube 41 is smaller than the diameter of the target conduit 60. Both the elastic sealing tube 41 and the elastic strip 42 are made of an elastic material, such as rubber.

[0038] A sealing diaphragm 50 is connected to the sealing structure 40. The sealing diaphragm 50 has a cross-shaped slot 51 that extends through the sealing diaphragm 50. The diaphragm is used to close the orifice of the elastic sealing tube 41 when the target conduit 60 is separated from the sealing structure 40.

[0039] When the target conduit 60 is inserted into the sealing structure 40 in the direction from the first end S1 to the second end S2, the operator's fingers grip the sealing structure 40 to prevent it from sliding within the liquid flow channel 32. Since the orifice of the elastic sealing tube 41 is smaller than the diameter of the target conduit 60, the elastic sealing tube 41 undergoes elastic deformation. Under the action of elastic force, the sidewall of the elastic sealing tube 41 abuts against the sidewall of the target conduit 60 to seal the liquid flow channel 31 and prevent liquid leakage.

[0040] As the target conduit 60 separates from the elastic sealing tube 41 along the direction from the second end S2 to the first end S1, since one end of the elastic strip 42 is connected to the elastic sealing tube 41 and the other end of the elastic strip 42 is connected to the second end S2, the elastic strip 42 undergoes elastic deformation to generate elastic tension within it. Under the action of the elastic force of the elastic strip 42, it prevents the elastic sealing tube from moving to the first side of the first end S1 away from the second end S2 driven by the target conduit 60, thus facilitating the next insertion of the target conduit 60 into the elastic sealing tube 41.

[0041] There are multiple elastic strips 42, which are evenly spaced along the circumference of the sealing structure 40. As the target conduit 60 separates from the elastic sealing tube 41 in the direction from the second end S2 to the first end S1, a uniform tension is provided on the elastic sealing tube 41 in the circumference of the elastic sealing tube 41.

[0042] When the target conduit 60 is inserted into the sealing structure 40, the target conduit 60 is inserted into the cross-shaped slot 51, the sealing diaphragm 50 undergoes elastic deformation, and when the target conduit 60 separates from the slot 51, the elastic diaphragm resets to prevent liquid leakage.

[0043] In this application, the sealing structure 40 also includes a connecting rod 43, a first fixing ring 44, and a second fixing ring 45.

[0044] The first fixing ring 44 is connected to the connecting rod 43 on one side of the first end S1. The end of the elastic sealing tube 41 away from the elastic strip 42 is connected to the first fixing ring 44. The first fixing ring 44 is provided with a first through hole 441.

[0045] The second fixing ring 45 is connected to the connecting rod 43 on one side of the second end S2. The end of the elastic strip 42 away from the elastic sealing tube 41 is connected to the second fixing ring 45. The second fixing ring 45 is provided with a second through hole 451.

[0046] The first through hole 441 and the second through hole 451 are coaxially arranged, and the diameter of the first through hole 441 is equal to the diameter of the second through hole 451. The diameter of the second through hole 451 is greater than the diameter of the target conduit 60, so that the target conduit 60 can extend into the airbag 20 after passing through the sealing structure 40.

[0047] When the target conduit 60 is inserted into the sealing structure 40 in the direction from the first end S1 to the second end S2, the operator's fingers hold the first fixing ring 44 or the second fixing ring 45 to fix the sealing mechanism 40 and prevent the sealing structure 40 from sliding in the liquid flow channel 32.

[0048] In this application, the sealing diaphragm 50 is installed in the first through hole 441 or the second through hole 451.

[0049] Compared with the prior art, the leakage-proof catheter insertion simulation training device provided in this application includes a dummy body 10, an airbag 20, a tube body 30, a sealing structure 40, and a sealing diaphragm 50. The airbag 20 is installed inside the dummy body 10, and the tube body 30 is connected to the airbag 20. A liquid flow channel 31 is formed inside the tube body 30. The sealing structure 40 is installed inside the liquid flow channel 31 and has a first end S1 and a second end S2. The sealing structure 40 includes an elastic sealing tube 41 and an elastic strip 42. One end of the elastic sealing tube 41 is fixed to the first end S1. The elastic sealing tube 41 is fixedly connected to the other end of the elastic strip 42. The end of the elastic strip 42 away from the elastic sealing tube 41 is fixedly connected to the second end S2. The orifice of the elastic sealing tube 41 is smaller than the diameter of the target conduit 60. The sealing diaphragm 50 is connected to the sealing structure 40 and is used to close the orifice of the elastic sealing tube 41 when the target conduit 60 is separated from the sealing structure 40. When the target conduit 60 is inserted into the sealing structure 40, the elastic sealing tube 41 abuts against the side wall of the target conduit 60 under its elastic force to prevent liquid leakage.

[0050] 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.
