Technical Field
[0001] The utility model specifically relates to a teaching mold for a rope ladder puncture method for an arteriovenous fistula. Background Art
[0002] As the number of patients with uremia increases, the demand for hemodialysis treatment is also growing. In hemodialysis treatment, arteriovenous fistula is an important channel connecting the patient's artery and vein, which is used to draw blood out of the body for purification and then return to the body. Due to the frequency of dialysis treatment, the fistula blood vessels need to be punctured frequently, which causes great damage and pressure to the patient's blood vessels. Therefore, the use of reasonable puncture methods, such as rope ladder puncture, is of great significance to reduce complications and protect the patient's lifeline.
[0003] The rope-ladder puncture method avoids repeated damage to the blood vessels in the same area in a short period of time by dispersing the puncture points, providing sufficient time for the blood vessels to heal, thereby effectively reducing the occurrence of complications such as pseudoaneurysm, thrombosis, and infection.

DETAILED DESCRIPTION
[0029] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0030] See also Figures 1 to 4 The utility model provides a teaching mold for arteriovenous fistula rope ladder puncture method, including a bottom plate 100, a simulated blood vessel 200, a puncture identification part 300 and a shape and position adjustment part 400.
[0031] Specifically, the simulated blood vessel 200 includes a tube body, which is transparent and elastic, and can be bent and deformed when subjected to external force. The tube body is laid on the bottom plate 100 along the length direction of the bottom plate 100, and the injection needle can be inserted into the tube body. The transparent body is used to facilitate the puncturist to penetrate the inside of the tube body, and the elasticity can simulate the elasticity of the blood vessel, and can be bent and deformed when subjected to external force to simulate blood vessels with different directions.
[0032] The puncture identification member 300 includes a rope body 310 and puncture identification points 320. The rope body 310 is embedded in the tube body at intervals along the length direction of the tube body, and a plurality of puncture identification points 320 are evenly spaced along the length direction on the upper surface of the rope body 310. When performing puncture, the puncturist can refer to the puncture identification points 320 for puncture. In specific implementation, the puncture identification points 320 can be evenly spaced at a distance of 0.5-1 cm.
[0033] There are multiple shape and position adjusting members 400, which are arranged at intervals along the extension of the tube body, and the ends of the shape and position adjusting members 400 are connected to the side walls of the tube body, which can drive the tube body to move along the width direction of the bottom plate 100. When in use, the position of the tube body can be adjusted laterally through the shape and position adjusting members 400, so as to adjust the direction and curvature of the blood vessel.
[0034] When in use, the shape and position adjusting parts 400 are first adjusted according to the direction and curvature of the patient's blood vessels, and then the puncturer can refer to the puncture marking points 320 to practice puncture until he is proficient in puncture.
[0035] In a specific implementation, a number may be set on each puncture mark point 320 to facilitate identification of different puncture points.
[0036] In this embodiment, the shape and position adjusting member 400 includes a fixing block 410, a push rod 420 and a locking member 430. The fixing block 410 is fixed on the bottom plate 100, the push rod 420 is arranged along the width direction of the bottom plate 100 and can be slidably plugged with the fixing block 410, and the end of the push rod 420 is hinged to the tube body, and the locking member 430 is arranged on the fixing block 410 for locking the push rod 420.
[0037] When in use, first unlock the locking member 430, then push or pull the push rod 420 to adjust the shape of the tube body. After adjustment, lock the locking member 430. In this embodiment, the locking member 430 includes a jacking screw, which is threadedly connected to the fixing block 410. When in use, the jacking screw is rotated so that the jacking screw can be pressed against the side wall of the push rod 420, thereby fixing the push rod 420; on the contrary, when the jacking screw is loosened, the push rod 420 can be moved.
[0038] As a preferred embodiment, the device further includes a winding assembly 500. There are two winding assemblies 500, which are respectively located at the two ends of the simulated blood vessel 200. The two ends of the rope body 310 pass through the tube body and are wound around the winding assembly 500. The winding assembly 500 can be used for winding or releasing the line.
[0039] When in use, the two winding components 500 are used to reel in or unreel the wire, so that the rope body 310 can be moved, thereby moving the position of the puncture mark point 320 to simulate the puncture operation under different vascular conditions, which helps students to become familiar with and master the puncture skills under different vascular conditions.
[0040] Specifically, the winding assembly 500 includes a winding shaft 510 and a rotating handle 520. The winding shaft 510 is rotatably arranged on the bottom plate 100, the end of the rope body 310 is wound on the winding shaft 510, and the rotating handle 520 is arranged at the end of the winding shaft 510, and the winding shaft 510 can be driven to rotate by rotating the handle 520. When the position of the puncture mark point 320 needs to be moved, the two winding shafts 510 are driven to rotate in the same direction by the handle, so that the rope body 310 can be driven to move, thereby realizing the change of the position of the puncture mark point 320.
[0041] In addition, in order to prevent the rope body 310 from moving around in the tube body, a guide hole parallel to its axis can be opened in the tube body, and the rope body 310 can be slidably inserted into the guide hole. The direction of the rope body 310 can be standardized through the guidance of the guide hole, thereby improving the position accuracy of the puncture mark point 320.
[0042] As another preferred embodiment, both ends of the tube body can be set to be closed, and the tube body is filled with red liquid. The red liquid simulates blood, and when the puncture needle pierces the blood vessel, the red liquid will flow into the injection needle, thereby improving the intuitiveness of the simulation exercise.
[0043] It should be noted that, in this case, the material of the tube body should be a material that can automatically close the needle hole when the injection needle is withdrawn, such as transparent VC plastic, PE plastic, ABS plastic, etc.
[0044] As a more preferred embodiment, the device further comprises a liquid injection mechanism 600, which is connected to the inner cavity of the tube body through a liquid injection tube, and the liquid injection mechanism 600 can inject red liquid into the tube body.
[0045] When it is found that the red liquid in the tube body is insufficient, the red liquid can be added to the tube body through the liquid injection mechanism 600.
[0046] How to use the above-mentioned arteriovenous fistula rope ladder puncture teaching mold:
[0047] When in use, first loosen the tightening screw, and push the push rod 420 according to the direction and curvature of the patient's blood vessels to adjust the direction and curvature of the blood vessels. Then, the puncturer can refer to the puncture mark point 320 to practice puncture until the puncture is proficient.
[0048] When the position of the puncture mark point 320 needs to be adjusted, the two winding shafts 510 are driven to rotate in the same direction, and the rope body 310 is pulled to move, and the puncture mark point 320 is adjusted to the required position.
[0049] By using the above-mentioned arteriovenous fistula rope ladder puncture method teaching mold, the shape of the simulated blood vessel 200 can be adjusted, and the position of the puncture point can also be adjusted, so that students can better understand, become familiar with and master the operating skills of the rope ladder puncture method under different vascular conditions.
