Abstract
A hollow needle carried in a hub, the needle and hub being carried on the end of tubing in flow-communicating relation between the needle and tubing. The hub defines typically a pair of wings extending transversely outwardly from the hub in opposite directions. The wings each carry plate members extending transversely of the wings to facilitate manual gripping of the needle hub. Preferably, the needle and hub further comprises a slidable, tubular guard defining a bore receiving the needle and hub. The tubular guard defines a pair of opposed, longitudinal slots through which the wings extend, with the plate members positioned outside of the tubular guard. The slots permit movement of the needle and hub in the guard from a needle-exposed position to a needle-enclosed position.

A hollow needle carried in a hub, said needle and hub being carried on the end of tubing in flow-communicating relation between said needle and tubing, said hub defining a pair of wings extending transversely outwardly from said hub in opposite directions, said wings each carrying plate members extending transversely of said wings, to facilitate manual gripping of said needle hub;
- a slidable, tubular guard defining a bore positioned to receive said needle and hub, said tubular guard defining a pair of opposed, longitudinal slots through which said wings extend with the plate numbers positioned outside of said tubular guard, said slots permitting movement of said needle and hub in the guard from a needle-exposed position to a needle-enclosed position, said guard defining a distal end;
- and an elongated anchor member carried by said guard adjacent to and extending distally from said distal end on one side of and spaced from said needle, to be manually held as the needle and hub are withdrawn from penetration of the vein of a patient, to cause sliding of said needle and hub relative to said guard from the needle-exposed to the needle-enclosed position.
A hollow needle carried in a hub, said needle and hub being carried on the end of tubing in flow-communicating relation between said needle and tubing, said hub defining at least one wing carrying a plate member extending transversely of said wing, to facilitate manual gripping of said needle hub;
- a slidable, tubular guard defining a bore positioned to receive said needle and hub, said tubular guard defining at least one longitudinal slot through which said wing extends with the plate member positioned outside of said tubular guard, said slot permitting movement of said needle and hub in the guard from a needle-exposed position to a needle-enclosed position, said guard defining a distal end;
- and an elongated anchor member carried by said guard adjacent to and extending distally from said distal end on one side of and spaced from said needle, to be manually held as the needle and hub are withdrawn for penetration of the vein of a patient, to cause sliding of said needle and hub relative to said guard from the needle-exposed to the needle-enclosed position.
A hollow needle carried in a hub, said needle and hub being carried on the end of tubing in flow-communicating relation between said needle and tubing, said hub defining a pair of wings extending transversely outwardly from said hub in opposite directions, said wings each carrying plate members extending transversely of said wings, in which said wings and plate members are made of a substantially rigid material, to facilitate manual gripping of said needle hub, and a slidable, tubular guard defining a bore positioned to receive said needle and hub, said tubular guard defining a pair of opposed, longitudinal slots through which said wings extend with the plate members positioned outside of said tubular guard, said slots permitting movement of said needle and hub in the guard from a needle-exposed position to a needle-enclosed position, said guard defining a distal end;
- and an elongated anchor member carried by said guard adjacent to and extending distally from said distal end on one side of and spaced from said needle, to be manually held as the needle and hub are withdrawn from penetration of the vein of a patient, to cause sliding of said needle and hub relative to said guard from the needle-exposed o the needle-enclosed position.
