The invention concerns an interfacing device () intended to connect a fluid injection instrument and a puncturable flask (), comprising:

Device for interfacing a fluid injection instrument with a puncturable flask and method for use thereof

The invention relates to a releasable blocking system () of a catheter (), comprising a base () adapted to receive a catheter (), and a shell (), mounted in rotation on the base () between an open position, in which the shell () is away from the base (), and a closed position, in which the shell ()is hooked on the base () and blocks the catheter () in position, in which: the system comprises an actuator () provided with a guide aperture (), mobile in a housing () between a rest position and a blocking position, the actuator () comprising a first drive element (), the shell ()comprises a second drive element (), adapted to cooperate with the first drive element () when the shell () is shifted from its open position to its closed position, and shift the actuator () to its blocking position.

The invention relates to a secure connector set for a liquid circuit, including: a male connector and a female connector, each including a proximal coupler and a distal coupler, the distal coupler of each connector defining a passage and including a tubular part, in which a connection member fixedly mounted on the proximal coupler extends coaxially, and an elastically deformable membrane which is substantially tubular, closed at a distal end by a membrane body, and movable between a downstream plugging position, in which the membrane sealingly covers a free end of the connection member, and an upstream connection position, in which the connection member passes through the membrane, in which the tubular part of the distal coupler of the male connector is designed to be inserted, upon connection, into the tubular part of the distal coupler of the female connector, and wherein, in a downstream plugging position, for the male and the female connectors, the membrane sealingly blocks the passage in the distal coupler.

Set of easily cleanable connectors for a liquid circuit

The conductor is composed of at least one layer () of a material (A) that conducts electricity, said layer being applied to the outer face of the lateral wall of the tube () and being insulated by a non-conductive sheath (B) applied to the layer, In said conductive layer () forming, at the distal end of the tube, a distal ring () that matches the shape of the rounded distal end of N the tube and is not covered by the insulating sheath (B) of the layer, so as to form a neurostimulation contact, and said conductive layer () forming, at the proximal end of the tube, a proximal ring () that is not covered by the insulating sheath (B), so as to form an electrical connection.

Neurostimulation catheter

According to the invention, the spring-effect deformation capacity of the valve () essentially relates to the plug (Sa) and to an intermediate valve portion () between the plug (Sa) and a tubular gap (). The valve () and the fixed end piece () are conformed so that the valve can be permanently tightened on the fixed end piece without forming a significant dead volume in said gap independently from the deformation of the valve, and so that the valve can be maintained on the fixed end piece () without any flexion under the action of the mobile end piece. The slot () of the valve includes a moulded proximal slot (A) followed by a pierced distal slot (B) for communication between the moulded slot and said gap when the slot is open. Application in medical fluid connectors.

The invention relates to a needle stick guard for an anti-needle-stick puncturing kit for positioning a catheter according to the Seldinger technique, including a rocker having a journal so as to enable same to rotate about an axis, and an outer tip for locking the needle stick guard together with a base of another element of the puncturing kit. The rocker comprises three positions: a position in which it is locked together with another element of the puncturing kit; a position in which it is unlocked from the other element of the puncturing kit; and a protection position for trapping a sharp end of a needle in the guard.

A device for introducing a catheter guide wire into a vessel of a patient has a connector and a straightener for a J-shaped end of the guide wire, the connector having an axial bore, and its distal end and proximal end permitting a connection of the Luer type to a needle and to a syringe, respectively. The connector supports, on its inside, a sealing valve equipped with a slit, and the axial bore has, in its portion between the sealing valve and the distal end of the connector, a leaktight mating surface, the shape of which is such that it permits liquid-tight mating with the outer surface of the distal end of the straightener, when the latter is introduced into the connector via the sealing valve.

A device for introducing a catheter into a body site through the skin by means of an security non-piercing cage includes a steel spring flexible blade which is disposed in the cross section of the chamber of the nonpiercing cage near the proximal input thereof perpendicularly to a needle and is penetrable by the needle. The blade and the needle are adapted to interact in such a way that the blade is in a resting position and freely transversable by the needle when the needle is pushed in a distal direction, and the blade stops the needle and is flexed thereby when the needle is pulled in a proximal direction beyond a determined axial position in such a way that the flexed blade tilts the needle and exposes the inclined needle to a restoring force which pushes the needle off in the distal direction until the puncture end is stopped against the chamber wall. The invention can be used for intravenous catheters.

A fluid connector, for use in the medical field, has a tubular male socket and a tubular female socket. Each socket includes a fitting end for an end piece and a nesting end. The female socket has external notches for axially retaining a locking collar which is fixed on the male socket by penetration of lugs into ports on the collar.
