Fluid handling couplings can be made to connect and disconnect other members of a fluid handling system. For example, this document describes fluid couplings that are convenient to couple/decouple and that provide strong resistance to inadvertent disconnection when subjected to rotation while pressurized. In some embodiments, the resistance to inadvertent disconnection is facilitated by a latch mechanism of the female coupling that includes a protrusion that becomes seated in a groove of a mated male coupling.

The present invention provides a connection device, as well as a connector and heat exchange device, both having the connection device. The connection device includes a plurality of first connectors, a casing, a pressing member and a fastening assembly. The plurality of the first connectors, the pressing member and the fastening assembly are all at least partially housed in the casing, and the pressing member has a pressing portion which is exposed out of the casing. The first connectors are adapted to mate with respective second connectors. The fastening assembly is configured to switch between a ready-to-fasten configuration and a fastening configuration and thereby change connection conditions between the first and second connectors. Firstly, the connection device of the present invention is overall simple in structure and space-saving. Secondly, connecting and fastening the male and female connectors using the pressing member and the fastening assembly allows fast mating and unmating to be achieved by convenient operations. Thirdly, fastening a plurality of connectors, such as multiple pairs of male and female connectors, using the single fastening assembly results in additional significant decreases in manufacturing cost, provides the user with increased convenience of use and enables easier operations.

A locking element (30) for releasably fixing a fluid-conducting plug (40) to a connector (10) that has at least one spring element (311) for a sprung preload into a locking position with at least one trigger element (35) for transferring from a receiving position into the locking position. At least two trigger elements (35) are provided on the locking element (30), wherein for a transfer to the locking position, a simultaneous actuation of the trigger elements (35) is required.

A locking member is mounted to the housing to be able to move in the outer diameter direction by a tapered portion of the tubular body, when the tubular body is inserted. The housing is equipped with slits formed to pass a curved portion bent in the inner diameter direction disposed at a leading-end side of the locking member and to lock with the engagement portion of the tubular body mounted on the housing. A gap is disposed between the curved portion, and the end portion of the slit positioned at a side in an opposite direction to the leading-end side of the locking member, so that there is no contact while at least the locking member is moving.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a sterile connection for drug delivery. In some embodiments, the fluid coupling devices can be implemented as multi-use, sterile fluid coupling devices that are configured to reduce the likelihood of fluid spillage when being disconnected.

This document describes fluid handling couplings. For example, this document describes fluid handling couplings that are genderless, that include manually openable valves, and that are configured for single-use aseptic fluid handling usage.

There is provided a tube coupling configured to connect and couple two tubes that are configured to cause a fluid to flow inside the two tubes. The tube coupling includes: a male connector including a first pipe configured to cause the fluid to flow inside the first pipe, and an insertion part having a protruding shape protruding in an axial direction that is an insertion direction; and a female connector including a second pipe configured to cause the fluid to flow inside the second pipe, and an insertion receiving part having a recessed shape recessed in the axial direction and coupled to the insertion part when the insertion part is inserted into the insertion receiving part. The insertion part includes a first spring, a first pressing member having a protruding shape, a first seal member having an annular shape, and a first outer peripheral member surrounding the first pressing member.

Provided is a quick connector assembly for joining a male member and a female connector member together to secure fluid communication in a fluid line system. The quick connector assembly includes a primary latch and a secondary latch configured to toggle between engaged and disengaged positions and to allow for a visual, audible, and/or tactile indication as to the status of a secure attachment between a male member and a female connector member.

A fluid female coupling element (11), comprising a female body (21), able to receive a male coupling element (2), a bolt (41), mounted sliding transversely between a holding position and a releasing position of the male coupling element and a plunger (51), movable between forward and rear positions. To automatically oppose the removal of the male element fitted within it, even if the male element has a reduced length, the female coupling element (11) comprises a memory ring (61), movable between an advanced position for holding the bolt (41) in the releasing position and a withdrawn position allowing the movement of the bolt (41) toward its holding position, the plunger (51) driving the memory ring (61) toward the withdrawn position when the plunger moves toward the rear position and the memory ring being in the advanced position in the uncoupled position.
