Estimating the term…
A shielded safety syringe comprising a cylindrical outer protective sleeve, a cylindrical inner needle carrier movable axially through the outer sleeve, and a double-ended hypodermic needle retained at a distal end of the needle carrier and movable with the carrier through the sleeve. A movement of the inner needle carrier through the outer protective sleeve corresponding causes the needle to be relocated from an axially extended position, at which to make a veni puncture through a patient's tissue, to a retracted position, at which the needle is completely surrounded and shielded by the outer sleeve to permit a safe handling and disposal of the syringe. A portion of the distal end of the needle carrier at which the needle is retained is pivotally connected to the needle carrier. When the needle is located in the retracted position, said distal end portion may be rotated and the needle thereby canted toward the outer sleeve to prevent both access to the needle and the return of the needle to the axially extended position, whereby to avoid an accidental needle strike and the spread of a contagious and, possibly life threatening, disease.
A syringe comprising an outer protective sleeve having proximal and distal ends and comprising:
A syringe comprising:
A syringe comprising an outer cylinder, a needle carrier movable axially through said outer cylinder, and a hypodermic needle retained by said needle carrier and movable therewith through said cylinder such that said needle can be advanced to a first position, at which said needle projects outwardly from said cylinder so that a fluid may be supplied via said needle to the interior of said cylinder, or said needle can be retracted to a second position, at which said needle is surrounded and shielded by said cylinder to prevent an accidental needle strike, said needle being hingedly interconnected with said needle carrier so as to be rotatable with respect to said needle carrier and thereby canted relative to the longitudinal axis of said outer cylinder when said needle is located at the second, retracted position surrounded by said cylinder.
