Obviously, such protection precludes use of the same needle for the aforementioned separate sampling purposes. The invention, therefore, furthe...

Problems solved by technology

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.
The open manipulation of the contaminated needle between withdrawal and sample securement presents unwanted hazards to personnel in the possibility of accidental needlestick injury.
Thus, the physical movement of the contaminated needle with one hand ...

Embodiment Construction

Referring to the drawings, there is generally indicated in FIGS. 1 and 2 a typical widely used blood collection and blood banking system which in use presents the aforementioned safety and needlestick hazards. Thus, a hollow metal cannula needle 10 having a tapered point 12 has a finger-grippable enlarged annulus 14 secured to a proximal needle portion to facilitate handling and maneuvering of the needle in the collection and sampling process.

The donor's skin is punctured by the point 12 and the same is the positioned in a blood vessel. The proximal end 16 of the needle is bonded, clamped, or otherwise secured in known manner to flexible tubing 18, the opposite end of which communicates with a blood collection bag 20, whereby the needle, tubing, and bag form a closed passageway for the flow of blood. Clamp means 22 of known form is provided along tubing 18 to regulate or shut off blood flow as may be required from time to time during collection or thereafter.

There is also provided a...

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...
