Blood pump and application thereof

摘要

Blood pump actuated by vacuum, which uses a tubular elastic membrane which is found on the inside of a rigid chamber and in which the blood intake is obtained by dilation of the membrane on submitting it to vacuum, and the propulsion by elastic recuperation of the membrane when the chamber is connected to the atmosphere. The propulsion direction is obtained by stenosizers of active external tube (also called pincer valves), instead of the classical mechanical valves, and placed in entrance and exit nozzles. The pump is actuated by a console which commands all its functions.
