发明名称 Pump for an artificial heart
摘要 A housing of a pump for an artificial heart comprises central, polar regions of rigid material where a rotatable connector for control and/or power supply conduits is located. An equatorial, peripheral region is made of flexible material. Connectors for inlet and outlet conduits are tangentially mounted to the equatorial region. A flat, torus shaped bellows of elastic material is positioned between two oppositely driven, spring loaded pressure plates and encloses the pump volume. An electromechanical displacement transducer provides signals proportional to the stroke of the pump. The pump may be operated by a liquid or gaseous pressure medium and its shape and structure are well adapted for implantation into a living organism, especially the human body.
