Injection site for tubular medical connectors
First Claim
1. An injection site for tubular medical connectors, comprising:
- a non-slitted perforable body configured for perforation by a needle during use, said perforable body received in a seat of a connector delimited by an annular wall having a turned-in retention edge turned in against an outer end of said perforable body;
said perforable body having a first end opposite said outer end and a side wall lateral to said first end;
said outer end of the perforable body having a peripheral annular step for engagement of said turned-in retention edge of said annular wall of the connector;
said peripheral annular step extending inwardly from said side wall;
said peripheral annular step bounded by an annular groove having a rounded wall complementary to that of said turned-in retention edge; and
said outer end having an exposed portion with a reduced cross section projecting axially beyond said peripheral annular step in an axial direction parallel to a longitudinal axis of said connector and away from said seat, said exposed portion projecting in said axial direction beyond said turned-in retention edge;
said annular groove extending from said peripheral annular step to connect to a lip of said exposed portion;
said lip projecting radially above said turned-in retention edge such that an outermost radial extent of said lip is radially inward of an outermost radial extent of said peripheral annular step.

Abstract
An injection site for tubular medical connectors, includes a perforable body inserted in a seat of a connector delimited by an annular wall having a retention edge turned in against the outer end of the perforable body. The outer end is formed with a peripheral annular step and with an exposed portion with reduced cross section projecting axially. The peripheral step is defined by an annular groove having a shape complementary to that of the turned-in retention edge of the connector, and the portion with reduced cross section of the perforable body connects up to the groove through an annular surface projecting radially above at least part of the turned-in retention edge and resting against it.
