The present invention relates to a male coupling with integrated shunt system for the application on a multi-coupling device of the plate type, as well as a multi-coupling device comprising said coupling with integrated shunt system.

The invention thus makes it possible to implement the shunt function on movable plate side, i.e. on the plate configured to support a plurality of male couplings so as to short-circuit the male couplings when the plates are uncoupled.

The present invention further relates to a kit comprising at least one pair of male couplings with integrated shunt system and to a connection plate configured to achieve the fluid connection between the two male couplings, as well as a multi-coupling device comprising such a kit.

A quick release coupling includes male and female connector assemblies releasably secured together. The male connector assembly includes two parallel male connectors and the female connector assembly includes two parallel female connectors. A sleeve assembly is releasably connected to one ends of the female connectors. A plunger assembly is provided in each of the sleeve assembly and female connector. A sleeving assembly is provided on each of the female connector and the sleeve assembly. The parallel female connectors can be disconnected from the parallel male connectors or connected together at the same time. After the female connectors have disengaged from the male connectors, leakproof arrangements in the female connector assembly act to prevent water in the female connector assembly from leaking.

A latch coupling includes male and female connector assemblies releasably secured together. The male connector assembly includes two parallel male connectors and first latches. The female connector assembly includes two parallel female connectors and second latches. A sleeve is releasably connected to an end of the female connector. Force is exerted on the second latches to hook the first latches so as to connect the female and male connector assemblies together. The parallel female connectors can be disconnected from the parallel male connectors or connected together at the same time.

A needleless connector includes a housing having a central longitudinal axis, a body portion, and a base portion. The body portion includes an inner surface forming an internal cavity, and a first port forming a first fluid passage to the housing cavity. The base portion includes a top end section and a bottom end section. The top end section has a protrusion, and the bottom end portion has a second port forming a second fluid passage to the housing cavity. The needleless connector further includes a valve having a wall with an inner surface forming a valve cavity. The valve is coupled with the housing such that the protrusion is positioned in the valve cavity, and a proximal end of the protrusion is spaced apart from a proximal end of the valve cavity.
