Detailed ways

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4: the utility model includes a human blood vessel model 2, a detachable stenosis and diseased blood vessel 4, an operation control circuit 1 and a catheter 3 for sending the stent to the inside of the human blood vessel model 2;

The human blood vessel model 2 is closely connected to the detachable stenotic and diseased blood vessel 4, and the detachable stenotic and diseased blood vessel 4 is built with two sets of built-in valve devices 41, and each set of built-in valve devices 41 has two valves 40;

The operation control circuit 1 is composed of a double position indicating circuit 101 and a timing circuit 102 electrically connected, the double position indicating circuit 101 includes a first button switch 14 and a second button switch 17 installed on the inner wall of the blood vessel of the human blood vessel model 2, the first button There are two switches 14 and second button switches 17 respectively, and they correspond to the valves 40 respectively.

Preferably, the built-in valve device 41 is mounted on the detachable stenotic blood vessel 4 by screws.

Preferably, the valve 40 is connected to the built-in valve device 41 through a hinge 44, and the valve 40 is opened in one direction along the entry direction of the catheter 3 and cannot be opened in reverse, and it is ensured that the valve just presses the corresponding valve when the built-in valve device 41 is opened in one direction. The first button switch 14 or the second button switch 17; after the stent is implanted in the detachable stenosis and diseased blood vessel 4, the stent can be taken out unidirectionally along the catheter 3 entering direction, and the detachable stenosis and diseased blood vessel 4 can continue to be used.

Preferably, the human blood vessel model 2 is transparent.

Preferably, the first button switch 14 is connected to the corresponding first relay 13, the first timer 10, the first indicator light 15 and the first music player 16; the second button switch 17 is connected to the corresponding The second relay 21, the second timer 20, the second arrival indicator light 18 and the second music player 19.

Preferably, the detachable stenotic blood vessel 4 is longer than the stent.

Preferably, the distance between the two built-in valve devices 41 is shorter than the length of the stent.
