Abstract
The present invention provides a deflectable guide whose use results in protection of the hand of medical personnel holding a medical container during the activity of moving a hypodermic needle toward and pressing it through a septum of the medical container. The present invention further is adapted for use of the same syringe and deflector guide protected needle for injection or withdrawal of medical liquids from a septum end of medical catheter or intravenous tubing without removal of the deflectable guide.
Claims12
An assembly of a syringe rigidly engaged at a syringe tip to a deflectable guide comprising:
- (a) the deflectable guide comprising a hypodermic needle secured in a center of a round spacer support that extends radially and normally outward from an operating axis defined by a bore of the hypodermic needle and at an upper end of the hypodermic needle, wherefrom an integral adapter extends up from a top surface of the round spacer support adapted to be rigidly engaged or disengaged with a Luer lock, slip lock or other tip of the syringe;
- (b) two arcuate sections are supported in a downward direction from a periphery of the round spacer support, the arcuate sections having inside surfaces defining a cylindrical or frustro-conical protected space and sharing the operating axis where a free portion of the needle extends down from the round spacer support to the needle tip, which is always within the protected space;
- (c) the arcuate sections are returnably flexible at their connections at upper ends to the round spacer support:
- (i) so that lower ends of the arcuate sections deflect outward and away from the operating axis when the arcuate sections engage a container whose engaged diameter is greater than that of the round spacer support;
- and
- (d) the arcuate sections are optionally removable or engageable at upper edges to a bottom periphery of the round spacer support.
