Cardiopulmonary function assisting device

摘要

A cardiopulmonary function assisting device includes a gas guide tube (1) of which peripheral wall does not transmit gas or liquid such as blood and has a suitable rigidity and a suitable flexibility. A header (2) is coaxially attached to an opening at the distal end of the gas guide tube. A plurality of balloons (3) are attached to the distal end of the header. The balloons are formed of a gas permeable film and left in a blood vessel. Oxygen is supplied to the balloons through the gas guide tube, thereby expanding the balloons; oxygen is discharged from the balloons, thereby contracting the balloons. The expanding and contracting operations are repeated. As a result, when the balloons are expanded, oxygen is transmitted through the balloons and added to blood on the periphery of the balloons and the expanded balloons remove the blood away from the periphery. When the balloons are contracted, the periphery of the balloons is filled with blood. $$
