Set of easily cleanable connectors for a liquid circuit

摘要

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.

1. A secure connector set for a liquid circuit, comprising: a male connector and a female connector, each comprising a proximal coupler and a distal coupler, wherein the distal coupler of each of the male and female connectors defines a passage and comprises: a tubular part; a connection element mounted and fixed on the proximal coupler and extending coaxially in the tubular part; and an elastically deformable membrane, substantially tubular, closed at a distal end by a membrane thickness, wherein the elastically deformable membrane of the male connector is mobile between a downstream blocking position, in which the elastically deformable membrane of the male connector tightly covers a free end of the connection element of the male connector, and an upstream connection position, in which the connection element of the male connector passes through the elastically deformable membrane of the male connector, the male connector comprising a first elastic means configured to be supported on the proximal coupler of the male connector and to thrust the elastically deformable membrane of the male connector into the downstream blocking position, wherein the elastically deformable membrane of the female connector is mobile between a downstream blocking position, in which the elastically deformable membrane of the female connector tightly covers a free end of the connection element of the female connector, and an upstream connection position, in which the connection element of the female connector passes through the elastically deformable membrane of the female connector, the female connector comprising a second elastic means configured to bear on the proximal coupler of the female connector and to thrust the elastically deformable membrane of the female connector into the downstream blocking position, wherein the tubular part of the distal coupler of the male connector is adapted to be inserted, during connection, into the tubular part of the distal coupler of the female connector, and wherein, in a downstream blocking position, for each of the male and female connectors, the elastically deformable membrane of the male connector is encapsulated in the tubular part of the distal coupler of the male connector and sealingly blocks the passage of the distal coupler of the male connector and is flush with the distal end of the distal coupler of the male connector, and wherein, in a downstream blocking position, for the female connector, the elastically deformable membrane of the female connector is encapsulated in the tubular part of the distal coupler of the female connector and sealingly blocks the passage of the distal coupler of the female connector and is flush with the distal end of the distal coupler of the female connector.
