Abstract:
1. A needle safety device comprising: a needle having a tip and a cannula, wherein the needle cannula is in fluid communication with a chamber disposed inside a body of a housing comprising a handle, and wherein a proximal portion of the needle is fixed in a distal portion of the housing such that the body of the housing anchors the needle cannula extending into the body of the housing, and wherein the proximal portion of the needle cannula is deflected at an angle to exert tension on the needle cannula against a needle guide; an axial elongate element traversing the housing and having an integral needle point guard at a distal end thereof for arresting motion of the needle tip distal of the needle guide, wherein the needle cannula extends from the housing and is exposed along the length thereof such that the exposed length of the needle cannula and the housing are slidable along a length of the axial elongate element; a shield member having the needle guide disposed therein wherein movement of the housing causes the exposed needle cannula to engage the needle guide along the length of the exposed needle cannula; and means for arresting the movement of the handle located at a proximal end of the elongate element.
