VALVE COMPRESSION APPARATUS

Abstract: the present invention discloses a valve compression apparatus, belongs to the technical field of medical apparatus and instruments, and includes a compression shell, a communication tube, a funnel tube, a compression arc plate, and a pressing assembly; the communication tube is smoothly connected to a small-diameter end of the funnel tube; two opposite sides of the compression shell are provided with placement ports respectively, one placement port is communicated with the communication tube, and the other placement port is communicated with the funnel tube; a plurality of operation ports are arranged in a circumferential direction of the funnel tube; the pressing assembly includes a traction plate with a slope, an elastic support assembly, and a moving ring; when the moving ring moves in a direction from the communication tube to the funnel tube, the moving ring simultaneously squeezes a plurality of traction plates, to drive the traction plates to move towards the funnel tube; the compression arc plate is in a one-to-one correspondence with the operation port, and is connected to the traction plate through a connecting rod; when the traction plate moves towards the funnel tube, the compression arc plate passes through the operation port and moves towards an axis of the funnel tube, to quickly compress a valve and avoid damage in the valve compression process.
