Abstract

A safety needle and blood collection and sampling system precluding needlstick injury by contaminated needles wherein a used needle is captured immediately within its carrier upon retraction of the needle flush with the carrier. Blood sampling is effected without reverse flow through the system and without reuse or exposure of a contaminated needle. Simplified means of assembling the needle are also set forth to minimize cost with maximum reliability notwithstanding withstanding a minimum of components.

Description

BACKGROUND OF THE INVENTIONAt high-volume medical facilities as blood bank centers. hospitals, and the like, blood is drawn from human donors in large quantities for processing and storage. In connection therewith, small volume specimens of the blood are withdrawn from the blood collection apparatus for necessary analysis. Blood withdrawal from humans exposes the medical worker to the risk of accidental needlestick injuries preparatory to connection of blood collection equipment to the donor in the unavoidable handling of used, unshielded, blood-contaminated needles.In current practice, blood banking services, such as the American Red Cross among others, obtain, process, and store whole blood and blood components for a variety of medical uses such as transfusions and the like. Before any such blood can be used, however, all collected blood is analyzed to characterize its immune properties or so-called "blood type". Equally or more importantly, all blood must also be pre-tested for t...
