[Gas volume stabilization in the pneumatic transmission unit of the assisted circulation apparatus]

A compensator connected to the section consisting of the pump-main line-operating member and including a pneumatic resistance and a flaxid non-elastic container enables it in combination with the feedback to maintain through the volumetric displacement of the gas, or changing the pump diaphragm position, the stability of the gas volume in the pneumatic transmission element of the assisted circulation apparatus. The stabilization of the gas volume in the pneumatic transmission element creates favourable conditions of exploitation and heightens the effect of the cardiac insufficiency treatment, expecially in cases of protracted assisted circulation.
