Abstract
A passive safety needle shield (300) is provided. The needle shield comprises a base (302) fixed to a proximal end of a needle, and an enclosure housing (304) initially disposed at a distal end of the needle, and enclosing the end of the needle. A hinged arm (306) connects the base (302) and the enclosure housing (304). The enclosure housing (304) is slidable along the needle length, and the hinged arm (306) flexes to permit the enclosure housing (304) to move along the needle as the needle is inserted into a user, thereby hiding the needle end, and providing support to the needle to avoid bends or buckles in the needle. The hinged arm (306) is biases in the initial position so that the enclosure housing (304) returns to the end of the needle as the needle is withdrawn.

A safety shield for a needle, comprising,
- a base member fixed to a proximal end of a needle;
- a first arm hinged to the base member and extending axially from the needle,
- a second arm hinged to the first arm, the second arm also hinged to an enclosure housing movably connected to a portion of the needle distal to the proximal end of the needle, and slidable along the length of the needle, the enclosure housing adapted to contact the skin of a patient, and guide the needle into the patient during insertion of the needle into the patient;
- wherein the first and second arm bias the enclosure housing towards the distal end of the needle.
A safety shield for a needle, comprising,
- a base member fixed to a proximal end of a needle;
- a curved biasing arm connected to the base member and extending axially from the needle,
- the biasing arm also being connected at an opposite end to an enclosure housing movably connected to a portion of the needle distal to the proximal end of the needle, and slidable along the length of the needle, the enclosure housing adapted to contact the skin of a patient, and guide the needle into the patient during insertion of the needle into the patient;
- wherein the curved biasing arm biases the enclosure housing towards the distal end of the needle.
