Abstract
A cardiac pump is arranged to mimic triphasic operation. The pump uses a fluid line formed from flexible tubing, along with a reciprocating actuator arranged to move between a free orientation and an occluding orientation. This allows a portion of the fluid line to be selectively occluded during movement of the actuator, enabling blood or other fluids to be peristaltically forced fluid towards a fluid outlet. The direction of operation of the actuator, and the selection of appropriate occluding or free orientations, allows the pump to be operated in a triphasic manner.
Claims18
A cardiac pump having a fluid line formed from flexible tubing, the fluid line having a first portion which acts as an inlet line, a second connecting portion, and a third portion which acts as a return line, the cardiac pump having a reciprocating actuator, the actuator having a first actuating member arranged to move between a free orientation and an occluding orientation such that the first actuating member at least partially occludes the first portion of the fluid line when in the occluding orientation of the first actuating member;
- the actuator having a second actuating member arranged to move between a free orientation and an occluding orientation such that the second actuating member at least partially occludes the third portion of the fluid line when in the occluding orientation of the second actuating member;
- the cardiac pump being operable such that when the actuator moves away from an inlet the first actuating member may be in the occluding orientation of the first actuating member so as to peristaltically force fluid towards a fluid outlet, and when the actuator moves towards the inlet the second actuating member may be in the occluding orientation of the second actuating member so as to peristaltically force fluid towards the fluid outlet.
