摘要：a small pump, and economic measure is especially useful in food and

intravenous (iv) includes a disposable pump chamber (10) and a pump body (12).the pumpchamber has a burner (10), an inlet (14) and an outlet (16), a first and a second chamber(26) for winding a flexible diaphragm pump.a first cylinder and a second cylinder (32) and(34) in the pump body is arranged to receive the first diaphragm.a flexible coil (24) andthe second diaphragm has a flexible coil (26) of the disposable pump chamber (10).a firstpiston, a second piston (38) and (40) are movable within the first cylinder and the secondcylinder (24), (26), respectively.in addition, a first valve, a second valve (44) and (46) aremounted in the pump body (12).the first control valve (44) of the fluid flow between theinlet and the first chamber of the diaphragm pump is a flexible coil (24).while the secondcontrol valve (44) of the fluid flow between the first chamber of the diaphragm pump is aflexible coil (24) and the second chamber is a enroulemen diaphragm pumpt hose (26). amotor has a shaft (94) and cam (96) causes the first piston and the second piston (38) and(40), and the first valve and the second valve (44) and (46).the first valve and the secondvalve (44) and (46) are commanded, so that a valve is closed at all times, thus ensuringfoolproof operation of the pump.
