Abstract
Abstract A catheter adapter comprising a body member having a recess for receiving a catheter. The recess is defined, at least in part, by a plurality of coaxial cylindrical surfaces of diameters corresponding to a plurality of different standard catheter outer diameters. A second member, formed from a resilient material, engages the body member adjacent the recess therein and has an opening for admitting a catheter to that recess. The opening is coaxial with the cylindrical surfaces and has a diameter, when the resilient material is unstressed, which is no greater than the diameter of the smallest of the cylindrical surfaces in the recess. The cylindrical surfaces are arranged according to size with the largest diameter cylindrical surface being disposed closest to the opening in the second member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A catheter adapter, comprising a body member having a first recess for receiving a catheter, said first recess defined, at least in part by a plurality of coaxial cylindrical surfaces of diameters corresponding to a plurality of different standard catheter outer diameters; a second member formed from a resilient material engaging said rigid body member to enclose said first recess and having an opening therethrough for admitting a catheter to said first recess, said opening being coaxial with said cylindrical surfaces and having a diameter, when said resilient material is unstressed, no greater than the diameter of the smallest of said cylindrical surfaces; said plurality of cylindrical surfaces being arranged according to size with the largest diameter cylindrical surface being disposed closest to said opening in said second member.
Claim 2
Dependent Claim
129 words
A catheter adapter, comprising a body member having a first recess for receiving a catheter, said first recess defined, at least in part by a plurality of coaxial cylindrical surfaces of diameters corresponding to a plurality of different standard catheter outer diameters; a second member formed from a resilient material engaging said rigid body member to enclose said first recess and having an opening therethrough for admitting a catheter to said first recess, said opening being coaxial with said cylindrical surfaces and having a diameter, when said resilient material is unstressed, no greater than the diameter of the smallest of said cylindrical surfaces; said plurality of cylindrical surfaces being arranged according to size with the largest diameter cylindrical surface being disposed closest to said opening in said second member.
Claim 3
Dependent Claim
28 words
