This document describes aseptic fluid coupling devices for fluid systems and methods of manufacturing such aseptic fluid coupling devices. For example, this document describes aseptic fluid coupling devices that include removable membrane strips that protect the interior of the aseptic fluid coupling devices from contamination prior to use. Methods for attaching removable membranes to the aseptic fluid coupling devices are also described.

This female element of a quick connector that connects to a male element and has a hollow body, which extends along an insertion axis and which delimits a receiving volume for the male element. Radial openings, formed in the body along a radial axis, open into the receiving volume. Each radial opening receives a latch, translatable in relation to the body along the corresponding radial axis, between a locked and an unlocked position. The female element has an actuating ring arranged about the body and translatable between a locked and an unlocked position. The ring has guide grooves, which interact with pins of each latch. The guide grooves associated with each latch are geometrically carried by a guide plane inclined in relation to the insertion axis so that each latch is driven between its locked and unlocked positions when the actuating ring is moved between its locked and unlocked positions.

A female coupling device includes: a main body, and a clip member coupled to the main body, the clip member having a plurality of arms extending perpendicularly therefrom, with the plurality of arms forming at least one pair of arms, with the pair of arms including a first distance therebetween and a second distance therebetween, with the first distance being sized to engage a clip groove of a mating male coupling device, and with the second distance being sized to disengage the mating male coupling device. In a locked position, the pair of arms is positioned so that the first distance is adjacent to the mating male coupling device. In an unlocked position, the pair of arms is positioned so that the second distance is adjacent to the mating male coupling device.

An aseptic connector includes first and second matable housings each comprising a plurality of connectors for fluid conduits. The fluid conduits enter the housings and may be force-fitted onto barbs or flanges on one side of the connectors, or may instead be molded directly onto the connectors. When the housings are joined, the opposite sides of the connectors mate to form fluid seals, thereby establishing fluid pathways between now-connected sets of tubes.

A bag connector system includes a first coupling element, with a self-closing seal and a housing having a fluid inlet port and a fluid outlet port, and a second coupling element, with a housing having a fluid inlet end and a fluid outlet end. The fluid inlet end is configured to displace the self-closing seal when inserted into the fluid outlet port of the first coupling element. A bag connector system optionally includes a locking mechanism to maintain the first coupling element and second coupling element in a coupled state. Uncoupling of the first and second coupling elements results in minimal fluid contamination on the outer surfaces of the coupling elements. The bag connector systems provided herein are included in medical appliances for waste management.

The invention relates to a coupling component for a fluid coupling (1) for releasably connecting fluid-conveying components, in particular fluid-conveying components in medical equipment, wherein the coupling component comprises a coupling housing (14) through which a fluid channel (17) passes in regions and which is provided with a coupling recess (7) that is sunken into a surface (15) of the coupling housing (14), wherein a channel opening (18) of the fluid channel (17) ends at an end face (19) of the coupling recess (7). According to the invention, it is provided that the channel opening (18) is covered by a membrane seal (4) which is made of a resilient material and through which a fluid gap passes (8) that is designed such that the membrane seal (4), when in a resting position, seals the channel opening (18) and, when in an operative position, opens the channel opening (18), wherein at least one yielding depression (29) is formed in the coupling recess (7) adjacently to the channel opening (18), which depression is designed for an yielding movement of a region (36, 37) of the membrane seal (4) when the membrane seal (4) transitions from the resting position into the operative position.
