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.

A coupler for a fluid transport system comprising a handle being continuous around the coupler, the coupler having a first end and a second end, the handle having a non-constant radius with respect to the central longitudinal axis of the coupler, the handle comprising a plurality of regions being proximal the first end of the coupler, and a plurality of regions being distal the first end of the coupler.

Couplers are described herein. A coupler includes a coupler body, a plurality of first retaining fingers, and a plurality of second retaining fingers. The coupler body includes a first end and a second end, and defining a cavity, the cavity configured to receive a first connector and a second connector. The plurality of first retaining fingers are configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The plurality of second retaining fingers are configured to engage against a shoulder of the second connector with a retention force, and release the second connector by radially expanding in response to a pullout force exerted on the second connector exceeding the retention force.

An assembly, connector and process for a quick connector includes a receptacle having first and second interior passages including a chamber in fluid communication between the first and second passages. A flow control insert is installed in the chamber to regulate fluid flow between the first and the second passage.

A fluid line quick connector for joining fluid lines together, such as coolant fluid lines in electric vehicle automobile applications, among other possible applications. A check valve is incorporated into the fluid line quick connector in order to preclude unwanted backflow through a passage of the fluid line quick connector. The check valve has a rigid partition wall and a flexible diaphragm. The partition wall has one or more through-holes residing therein. The diaphragm closes the through-hole(s), and moves relative to the partition wall in order to open a portion or more of the through-hole(s).

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.
