[Design and test of non-blood contacting pneumatic ventricle assistance device].

This paper presents a design of non-blood contacting pneumatic ventricle assistance device, which consisted of several parts, such as dual-cavity cardiac assistance cup, ventricle assistance controller, computer, vacuum pump, and air compressor. And the performance of the non-blood contacting pneumatic ventricle assistance device on mock circulation loop is introduced, which is very close to the normal cardiac output.
