Abstract
Abstract A syringe needle cap resheathing and removal apparatus is capable of single-handedly resheathing and removing needle caps of three different standard needle cap shapes. The apparatus can be fastened with an overcenter clamp to a patient's bed rail or other convenient location within a hospital. Three needle cap stations reachable by a common access gap in the apparatus correspond to three standard types of needle caps. The gap is angled to the horizontal to permit convenient visual and mechanical access to the respective needle cap operational stations. The apparatus can be rotated relative to the attachment of the clamp for the convenience and preference of the nurse or doctor.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
272 words
A syringe needle cap removal and resheathing apparatus comprising: a base; a first arm attached to said base; a second arm also attached to said base and separated from said first arm by a needle cap receiving gap having an opening opposite from said base, wherein a needle cap is firmly holdable in said gap when said cap is introduced sidewise into said opening and moved downwardly toward said base until further downward movement substantially stops at which point said syringe can be pulled away from said needle cap, wherein said first and second arms are made of materials that permit them to flex with respect to each other so that a needle cap can jam fit into said gap, and wherein said gap between said first and second arm includes at least a first and a second station for removing and resheathing needle caps of at least a first and a second kind having respectively two different barrel shapes; a clamp attached to said base for selectively clamping said apparatus to a stationary object; a swivel means attached between said clamp and said base for permitting said base to rotate with respect to said clamp; a third arm attached to said base and located adjacent to one of said other arms to limit the flexing of the arm that it is located adjacent to; and blade means located in at last one of said two stations for cutting into said needle cap as said needle cap is jammed into said gap and for holding onto said needle cap when force is applied to said needle cap perpendicular to said blade means.
Claim 2
Dependent Claim
272 words
A syringe needle cap removal and resheathing apparatus comprising: a base; a first arm attached to said base; a second arm also attached to said base and separated from said first arm by a needle cap receiving gap having an opening opposite from said base, wherein a needle cap is firmly holdable in said gap when said cap is introduced sidewise into said opening and moved downwardly toward said base until further downward movement substantially stops at which point said syringe can be pulled away from said needle cap, wherein said first and second arms are made of materials that permit them to flex with respect to each other so that a needle cap can jam fit into said gap, and wherein said gap between said first and second arm includes at least a first and a second station for removing and resheathing needle caps of at least a first and a second kind having respectively two different barrel shapes; a clamp attached to said base for selectively clamping said apparatus to a stationary object; a swivel means attached between said clamp and said base for permitting said base to rotate with respect to said clamp; a third arm attached to said base and located adjacent to one of said other arms to limit the flexing of the arm that it is located adjacent to; and blade means located in at last one of said two stations for cutting into said needle cap as said needle cap is jammed into said gap and for holding onto said needle cap when force is applied to said needle cap perpendicular to said blade means.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 wherein said blade means comprise at least two sharp blades oriented substantially parallel to the long axis of said gap.
Claim 4
Dependent Claim
30 words
The apparatus of claim 2 further comprising a third station located in said gap for removing a cap of at least a third kind having a third different barrel size.
Claim 5
Dependent Claim
19 words
The apparatus of claim 3 wherein said first and second arms and said base comprise a single integrated unit.
Claim 6
Dependent Claim
23 words
The apparatus of claim 4 wherein at least a portion of said first arm comprises a removable insert for carrying said blade means.
Claim 7
Dependent Claim
34 words
The apparatus of claim 5 further comprising: said base includes a plurality of recess stops; and, said clamp includes a swivel platform with a projection, wherein said projection engages one of said recess stops.
Claim 8
Dependent Claim
20 words
The apparatus of claim 6 wherein said base has a surface ranging from 20 to 25 degrees from the horizontal.
Claim 9
Dependent Claim

The apparatus of claim 7 further comprising: a third station having a plurality of ridges for holding onto said needle cap when said cap is jammed into said gap.
Claim 10
Dependent Claim
41 words
The apparatus of claim 8 further comprising: ledge means located in at least one of said two stations for holding needle cap types having a barrel with two flat opposite surfaces when said needle cap type is jammed into said gap.
Claim 11
Dependent Claim
12 words
The apparatus of claim 1 wherein said clamp is an overcenter-type clamp.
Claim 12
Dependent Claim
100 words
A syringe needle cap removal and resheathing apparatus comprising: a base; a first arm attached to said base; a second arm also attached to said base and separated from said first arm by a needle cap receiving gap having an opening opposite from said base; and at least one blade mounted in said gap having means for cutting the surface of a needle cap when said needle cap is introduced into said gap and for holding onto said needle cap to prevent longitudinal movement of said needle cap when force is applied to said needle cap perpendicular to said blade.
Claim 13
Dependent Claim
100 words
A syringe needle cap removal and resheathing apparatus comprising: a base; a first arm attached to said base; a second arm also attached to said base and separated from said first arm by a needle cap receiving gap having an opening opposite from said base; and at least one blade mounted in said gap having means for cutting the surface of a needle cap when said needle cap is introduced into said gap and for holding onto said needle cap to prevent longitudinal movement of said needle cap when force is applied to said needle cap perpendicular to said blade.
Claim 14
Dependent Claim
18 words
