Abstract
Abstract To replace the customary short flexible tube with attached needle at one end and larger tube connector at its other end, a packaged sterile blood donor assembly is provided. The assembly includes a rigid body having a bore and being equipped at its forward end with a needle and at its rear end with a tube connector having a safety reversible cap. An exterior sleeve on the rigid body is lockable in two positions thereon with the needle in an exposed use position and with the needle retracted and locked in a safety non-use position rearwardly of a safety shield and elastic membrane on the forward end of the exterior sleeve. A discardable needle shield is also provided on the assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A safety blood donor apparatus comprising a body having a longitudinal bore, a needle fixed to one end of the body in communication with said bore and having a rear end disc provided on its periphery with an O-ring seal. a tube connector fixed to the other end of said body, a sleeve slidably and rotatably mounted on the exterior of said body and receiving said O-ring wipingly in the interior thereof, a safety shield having a bore and an elastic membrane fixed to the forward end of said sleeve with the bore of the safety shield and membrane being coaxially aligned with said needle, interengaging locking means on said body and sleeve whereby the sleeve may be locked to the body in a retracted position with the needle projecting through said membrane and through the bore of the safety shield and forwardly of the safety shield and may be locked to said body in a forwardly extending position with the needle bodily enclosed in said sleeve rearwardly of the safety shield and membrane, and a closure cap for the tube connector.
Claim 2
Dependent Claim

A safety blood donor apparatus comprising a body having a longitudinal bore, a needle fixed to one end of the body in communication with said bore and having a rear end disc provided on its periphery with an O-ring seal. a tube connector fixed to the other end of said body, a sleeve slidably and rotatably mounted on the exterior of said body and receiving said O-ring wipingly in the interior thereof, a safety shield having a bore and an elastic membrane fixed to the forward end of said sleeve with the bore of the safety shield and membrane being coaxially aligned with said needle, interengaging locking means on said body and sleeve whereby the sleeve may be locked to the body in a retracted position with the needle projecting through said membrane and through the bore of the safety shield and forwardly of the safety shield and may be locked to said body in a forwardly extending position with the needle bodily enclosed in said sleeve rearwardly of the safety shield and membrane, and a closure cap for the tube connector.
Claim 3
Dependent Claim
237 words
A safety blood donor apparatus comprising a body having a longitudinal bore, a needle fixed to one end of said body in communication with said bore, a tube connector fixed to the other end of said body, a sleeve slidably and rotatably mounted on the exterior of said body, a safety shield having a bore and an elastic membrane fixed to the forward end of said sleeve with the bore of the safety shield and membrane being coaxially aligned with said needle, interengaging locking means on said body and sleeve whereby the sleeve may be locked to the body in a retracted position with the needle projecting through said membrane and through the bore of the safety shield and forwardly of the safety shield and may be locked to said body in a forwardly extended position with the needle bodily enclosed in said sleeve rearwardly of the safety shield and membrane, a reversible closure cap for the tube connector adapted to be applied thereto selectively in readily releasable and non-releasable positions, and said tube connector including a nipple having an enlarged bead and being adapted to be coupled with a flexible tube leading to a receptacle for donated blood, and said reversible closure cap having a plain skirt on one end thereof having a slip fit on said nipple and having a locking skirt at its other end adapted to interlock with said bead in non-releasable manner.
Claim 4
Dependent Claim
237 words
A safety blood donor apparatus comprising a body having a longitudinal bore, a needle fixed to one end of said body in communication with said bore, a tube connector fixed to the other end of said body, a sleeve slidably and rotatably mounted on the exterior of said body, a safety shield having a bore and an elastic membrane fixed to the forward end of said sleeve with the bore of the safety shield and membrane being coaxially aligned with said needle, interengaging locking means on said body and sleeve whereby the sleeve may be locked to the body in a retracted position with the needle projecting through said membrane and through the bore of the safety shield and forwardly of the safety shield and may be locked to said body in a forwardly extended position with the needle bodily enclosed in said sleeve rearwardly of the safety shield and membrane, a reversible closure cap for the tube connector adapted to be applied thereto selectively in readily releasable and non-releasable positions, and said tube connector including a nipple having an enlarged bead and being adapted to be coupled with a flexible tube leading to a receptacle for donated blood, and said reversible closure cap having a plain skirt on one end thereof having a slip fit on said nipple and having a locking skirt at its other end adapted to interlock with said bead in non-releasable manner.
Claim 5
Dependent Claim
207 words
A safety blood donor apparatus comprising a body having a longitudinal bore, a needle fixed to one end of said body in communication with said bore, a tube connector fixed to the other end of said body, a sleeve slidably and rotatably mounted on the exterior of said body, a safety shield having a bore and an elastic membrane fixed to the forward end of said sleeve with the bore of the safety shield and membrane being coaxially aligned with said needle, interengaging locking means on said body and sleeve whereby the sleeve may be locked to the body in a retracted position with the needle projecting through said membrane and through the bore of the safety shield and forwardly of the safety shield and may be locked to said body in a forwardly extended position with the needle bodily enclosed in said sleeve rearwardly of the safety shield and membrane, a reversible closure cap for the tube connector adapted to be applied thereto selectively in readily releasable and non-releasable positions, a disc secured to the rear end of the needle and abutting the forward end of said body, and an O-ring seal on and surrounding said disc and wipingly engaging the interior surface of said sleeve.
