DIALYSIS FLUID PUMP, AND HEMODIALYSIS APPARATUS HAVING SAME
摘要
According to the present invention, a dialysis fluid pump comprises: a housing having an accommodating space formed therein; a dialysis fluid supply tube and a dialysis fluid recovery tube, at least a portion of each of which is accommodated in the accommodating space; a cam rotatably installed in the accommodating space; a motor for rotating the cam; and a first backflow pressure preventer and a second backflow pressure preventer adapted to be mobile in the accommodating space and be pushed by the cam. The dialysis fluid supply tube is made of a flexible material which can be contracted or relaxed, and one end thereof is connected to a dialysis fluid supply tank and the other end thereof is connected to a hemodialysis filter. The dialysis fluid recovery tube is made of a flexible material which can be contracted or relaxed, and one end thereof is connected to a dialysis fluid recovery tank and the other end thereof connected to the hemodialysis filter. The cam has a cam surface for pressing the dialysis fluid supply tube and recovery tube to discharge the dialysis fluid from the inside of the dialyzing fluid supply tube and of the dialyzing fluid recovery tube. The first backflow pressure preventer and the second backflow pressure preventer prevent the dialysis fluid from flowing backward through the dialysis fluid supply tube and the dialysis fluid recovery tube.
