Abstract
Abstract An injection site is disclosed comprising a self-sealing, puncturable member of resilient material and a housing wherein the puncturable member is compressibly confined by a swage-molded edge on the top of the housing. The injection site may be attached to an injection-receiving receptacle such as a medicament injection device as used in an assembly for intravenous administration.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
An injection site, comprising in combination: a. a self-sealing, puncturable member of resilient material, said puncturable member being a generally cylindrical body having a top surface on which is centrally located a flat, smooth surfaced raised projection, and b. a generally tubular, plastic housing wherein said puncturable member is compressibly confined, said housing having a top receptor portion whose inside diameter is greater than the inside diameter of the remaining portion of the housing so as to provide a ledge on which said puncturable member rests, the top receptor portion having a swage-molded top edge which extends over at least a portion of the top surface of said puncturable member, said swagemolded top edge being below the flat surface of said raised projection.
Claim 2
Dependent Claim
123 words
An injection site, comprising in combination: a. a self-sealing, puncturable member of resilient material, said puncturable member being a generally cylindrical body having a top surface on which is centrally located a flat, smooth surfaced raised projection, and b. a generally tubular, plastic housing wherein said puncturable member is compressibly confined, said housing having a top receptor portion whose inside diameter is greater than the inside diameter of the remaining portion of the housing so as to provide a ledge on which said puncturable member rests, the top receptor portion having a swage-molded top edge which extends over at least a portion of the top surface of said puncturable member, said swagemolded top edge being below the flat surface of said raised projection.
Claim 3
Dependent Claim
17 words
The injection site of claim 1 wherein the swagemolded top edge is an ultrasonically swage-molded top edge.
Claim 4
Dependent Claim
