SUCTION PUMP FOR DRAINING BODY FLUIDS FROM BODY CAVITIES

摘要

Suction pump is for excluding body fluid from body cavity and with bottom (1) and the elastic pump housing (2) with domed shape. The pump also has inlet valve (27) and outlet valve (17). The flexible deformation pump housing (2) by providing pump stroke causes to provide the elastic pump housing (2) with above-mentioned intake stroke towards bottom (1). In order to obtain only the small clearance volume pump housing (2) have a smooth inner surface and bottom have a concave inner side (8) correspond to the pump housing (2) of interior configuration its deformation intake stroke pump.
