Abstract
An extra corporeal blood tube injection site comprising a smooth blood conduit or tube, an elongated elastomeric sleeve surrounding a section of the tube, and a C-shaped needle-impenetrable member extending along and partially surrounding the sleeve which generates forces within the portion of the sleeve that is not covered by the C-shaped member sufficient to prevent air leakage into, or blood leakage from, the tube during needle penetration or after withdrawal of a needle.
