Abstract

Abstract A connector consists of a block 1 through which a main perfusion channel 2 passes, and which comprises a secondary channel 3, the secondary channel possessing an injection inlet 14 and an outlet 4 which emerges in the main channel 2 and is controlled by a seal 5 which is elastically deformable under pressure. The seal 5 is a hollow member of ogival internal shape, which is housed in the secondary channel 3 and which closely fits the internal surface thereof, thus blocking the outlet 4 by means of its concave part, which is directed towards the said outlet and is pierced with a micro-orifice 8. When a syringe (e.g. containing medicament) is inserted into inlet 14 and is pressurised, a pressure is created which forces the seal 5 open; the seal 5 closes automatically when this pressure drops. <IMAGE>

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 99 words
Connector consisting of a block through which a main perfusion channel passes, and which comprises a secondary channel, the secondary cnannel possessing an injection inlet and an outlet which emerges in the main channel and is controlled by a seal which is elastically deformable under pressure, characterised in that the said seal is a hollow member of ogival internal shape, which is housed in the secondary channel and which closely fits the internal surface thereof, thus blocking the said outlet by means of its concave part, which is directed towards the said outlet and is pierced with a micro-orifice.
Claim 2
Dependent Claim 99 words
Connector consisting of a block through which a main perfusion channel passes, and which comprises a secondary channel, the secondary cnannel possessing an injection inlet and an outlet which emerges in the main channel and is controlled by a seal which is elastically deformable under pressure, characterised in that the said seal is a hollow member of ogival internal shape, which is housed in the secondary channel and which closely fits the internal surface thereof, thus blocking the said outlet by means of its concave part, which is directed towards the said outlet and is pierced with a micro-orifice.
Claim 3
Dependent Claim 25 words
Connector according to Claim 1, characterised in that the seal possesses a shoulder butting against a corresponding shoulder on the wall of the secondary channel.
Claim 4
Dependent Claim 44 words
Connector according to Claim 1 or 2, characterised in that the inlet of the secondary channel is extended by means of a piece which constitutes a connector for the outlet of an injection apparatus and which serves as a support for a detachable cap.
Claim 5
Dependent Claim 25 words
Connector according to Claim 3, characterised in that the piece and the cap are manufactured in a single unit with a clamp which connects them.
Claim 6
Dependent Claim 31 words
Connector according to Claim 3 or 4, characterised in that the piece is introduced into the inlet of the secondary channel and butts against the inlet edge of the secondary channel.
Claim 7
Dependent Claim 30 words
Connector according to one of Claims 1 to 5, characterised in that the main channel is adapted at both its ends for the introduction of the connector into a line.
Claim 8
Dependent Claim 28 words
Connector according to one of Claims 1 to 5 characterised in that the main channel is provided at one end with a tube firmly fixed to the connector.
