After the needle is pulled out, the slider 6 is pushed to move from the first end of the chute 2a to the The second end, so that the elastic sheet 4 is compressed and deformed, and the bottom of the elastic sheet 4 bulges downward, so that the elastic sheet 4 presses the delivery point across the infusion patch; One end moves to the second end, so that the capacitor 10 in Figure 6 is connected to the circuit where the LED light 7 is located, and the capacitor 10 supplies power to the LED light 7, so that the LED light 7 lights up, indicating that the pressure on the puncture site begins to stop bleeding. After the predetermined time, the discharge of the capacitor 10 is completed, and the LED light 7 goes out, indicating that the hemostasis by pressing the puncture site has reached the preset time, and the operation of hemostasis by pressing is completed, and the pressing is stopped. In the present invention, before the needle pulling operation, the shrapnel 4 does not press the puncture point, and does not interfere with the medical worker's needle pulling operation. After the needle is pulled out, the shrapnel 4 bulges downward to press the puncture point to stop bleeding. The moving distance in the groove 2a is constant, so the deformation of the shrapnel 4 is the same, so the pressing force of the shrapnel 4 on the puncture point is constant, so that the problem of bleeding at the puncture point or subcutaneous congestion caused by insufficient pressing force can be avoided In addition, because the length of time that the LED light 7 is on is determined by the capacity of the capacitor 10, after the capacitor 10 is determined, the time for pressing to stop bleeding can be indicated by the time when the LED light 7 is on, which can avoid the occurrence of insufficient pressing time. The problem of bleeding at the puncture site or subcutaneous congestion occurs.

The present invention has been exemplarily described above, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned manner, as long as the various insubstantial improvements of the method concept and technical solutions of the present invention are adopted, or the present invention is implemented without improvement. The ideas and technical schemes directly applied to other occasions are within the protection scope of the present invention. The protection scope of the present invention should be determined by the protection scope defined in the claims.
