Abstract
Abstract A clamp for control of separation of couplers in intravenous feeding and monitoring systems that is open along its vertical length to receive and secure various infusion tubing couplers by embracing raised or soft areas of said couplers with its inner horizontal gripping ridges and grooves to prevent axial and radial movements that may cause leaking or separation of friction or needle insert connections.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A safety locking clamp to secure various size friction couplers in intravenous feeding systems comprising an elongated hollow tubular body formed of resiliant plastic material, said body being provided with an elongated slot extending the entire length of the body, said clamp body having an internal wall structure with ridge means formed internally around the circumference thereof at each end of said body, said clamp further having pull tab means extending laterally from the slot edges whereby said resiliant clamp body may be applied over a coupling by pulling the slot wider and thereafter releasing it over the coupling via said pull tab means, said clamp wall having increased thickness at the junction area of slot edges and pull tab means to provide added gripping strength to said clamp in this area.
Claim 2
Dependent Claim
132 words
A safety locking clamp to secure various size friction couplers in intravenous feeding systems comprising an elongated hollow tubular body formed of resiliant plastic material, said body being provided with an elongated slot extending the entire length of the body, said clamp body having an internal wall structure with ridge means formed internally around the circumference thereof at each end of said body, said clamp further having pull tab means extending laterally from the slot edges whereby said resiliant clamp body may be applied over a coupling by pulling the slot wider and thereafter releasing it over the coupling via said pull tab means, said clamp wall having increased thickness at the junction area of slot edges and pull tab means to provide added gripping strength to said clamp in this area.
Claim 3
Dependent Claim
35 words
A locking device as in claim 1 wherein said means of pulling open vertical slot in brace body is assisted by rigid pull tabs provided at either side of vertical slot extending out from opening.
Claim 4
Dependent Claim
45 words
A locking device as in claim 1 that provides one or more inner vertical grooves that become outer ridges along entire length of body of brace, serrating inner horizontal ridges and grooves allowing expansion of circumference of brace to fit the various sizes of couplings.
Claim 5
Dependent Claim
18 words
A safety locking clamp as described in claim 3 that provides the pull tabs described in claim 2.
Claim 6
Dependent Claim
42 words
A flexible safety locking clamp as described in claim 1 that provides an expanding slit at either or both ends of top of body of clamp to allow increase in end circumference of clamp to fit unequal size in various coupling ends.
Claim 7
Dependent Claim
46 words
A clamp as described in claims 1, 3 or 5 that provides an inner horizontal groove at one end to embrace raised rim of an angio-catheter and multiple inner horizontal ridges at the other end to grasp the near end of rubber pump on intravenous tubing.
Claim 8
Dependent Claim
21 words
A clamp as described in claim 6 that provides pull tabs to open vertical slot wider as described in claim 2.
