FIELD: pump building.
SUBSTANCE: invention relates to peristaltic pumps. Pump comprises a stator, a shaft with a rotor, two working elastic tubes with a check valve. Stator is made up of top and bottom parts. Two working elastic tubes are branches of one elastic tube in front of the pump inlet and have two taps and one check valve. In the lower part of the stator there are holes for input of working tubes inside the pump and output from it. Inside the stator there are two rotors made of two identical parts 7. Between two parts 7 of each rotor one roller 9 is fixed with provision of gap at compression of elastic tube. Each roller 9 is installed with possibility of rotation on a bearing. Each rotor is located on a cantilever fixed in coupling 12 shaft 13.
EFFECT: invention is aimed at creation of a peristaltic pump for pumping blood and maintaining human vital functions for a long period of time.
