Abstract
A cannula for infusion of blood into a blood vessel includes a flexible membrane member which is secured to the leading end of a blood admitting pipe. An end insert is secured to the leading end of the flexible membrane member, and a core member is fixedly connected to the end insert. A fluid passage opening is formed in either the end insert or the flexible membrane member so as to permit the discharge of a blood which is infused into the flexible membrane member from an external source through the blood admitting pipe. The flexible membrane member may be folded and wrapped around the core member when the cannula is to be inserted into a blood vessel. As the blood begins to be fed into the pipe, the flexible membrane member is caused to be inflated, and blood flows into a blood vessel from the flexible membrane member.
