Abstract

A syringe cannula holder having a split outer sleeve that can be folded around the cannula so as to engulf fully the cannula. The sleeve is held in place by a sliding retaining nut. A hinged, locking retainer holds the syringe within the sleeve.

Claims

1. A cannula holder for a syringe, comprising:

a) a barrel having a pair of split, retainer ring halves on one end;

b) a pair of semi-tubular outer sleeve halves connected on a proximal end by hinges to the barrel opposite the retainer ring halves; and

c) a retaining nut sized to fit over the barrel and the outer sleeve halves when the outer sleeve halves are pivoted together about the hinges.

2. The cannula holder of claim 1 wherein the barrel, retainer ring halves and outer sleeve halves are integrally molded plastic.

3. The cannula holder of claim 1 wherein the syringe has a flange and the retainer ring halves contain a means for retaining the flange within a recess in the retainer ring halves.

4. The cannula holder of claim 1 wherein the outer sleeve halves contain a ridge for frictionally holding the retaining nut at the distal end of the outer sleeve halves.

5. A cannula holder for a syringe, the syringe having a flange, comprising:

a) a barrel having a pair of split, retainer ring halves on one end;

b) a pair of semi-tubular outer sleeve halves having a ridge on a distal end connected on a proximal end by hinges to the barrel opposite the retainer ring halves;

c) means for retaining the flange within a recess in the retainer ring halves; and

d) a retaining nut sized to fit over the barrel and the outer sleeve halves when the outer sleeve halves are pivoted together about the hinges.

6. The cannula holder of claim 5 wherein the barrel, retainer ring halves and outer sleeve halves are integrally molded plastic.
