Abstract
Some fluid coupling devices described herein are configured for use in fluid systems. For example, some embodiments described in this document are single-use, aseptic fluid coupling devices that can be coupled to create a sterile flow path therethrough. Some such aseptic couplings are genderless couplings such that two identical aseptic couplings can be coupled together and then latched to form a robust connection between the aseptic couplings.
Claims16
An aseptic fluid coupling comprising:
- a main body defining a longitudinal axis, a bore, and a fluid flow path through the main body along the longitudinal axis, the main body comprising:
- a front face;
- and
- a termination that is at an opposite end of the main body relative to the front face;
- a seal member including a portion disposed within the bore and a portion extending from the front face around the longitudinal axis;
- a latch movably coupled to the main body, the latch configured to clamp the main body of the aseptic fluid coupling to a second main body of a mated second aseptic fluid coupling such that:
- (i) the seal member is compressed to a degree that ensures leak-proof operation and (ii) a robust mechanical connection is created between the aseptic fluid coupling and the mated second aseptic fluid coupling;
- a flexible membrane including a portion attached to the front face around the seal member to block contaminants from entering the fluid flow path, the membrane also including a tail end portion that is at an opposite end of the membrane in comparison to the portion attached to the front face;
- and
- a linkage rotatably coupled directly with the main body and rotatably coupled directly with the latch, wherein the linkage is configured to rotate about an axis perpendicular to the longitudinal axis of the main body to cause the latch to rotate relative to the main body.

- (i) the seal member is compressed to a degree that ensures leak-proof operation and (ii) a robust mechanical connection is created between the aseptic fluid coupling and the mated second aseptic fluid coupling;
- and
- a flexible membrane including a portion attached to the front face around the seal member to block contaminants from entering the fluid flow path, the membrane also including a tail end portion that is at an opposite end of the membrane in comparison to the portion attached to the front face.
