Fluid couplings
Fluid handling couplings can include a main body with a front face and defining a longitudinal axis. Fluid handling couplings can include a post extending parallel to the longitudinal axis, and a post receptacle. Fluid handling couplings can include a seal coupled to the main body around the longitudinal axis. A portion of the seal can protrude from the front face of the main body. Fluid handling couplings can include a removable membrane releasably attached to the front face of the main body and covering the portion of the seal protruding from the front face of the main body. Fluid handling couplings can be genderless, can include manually openable valves, and can be configured for single-use aseptic fluid handling usage.
1. A fluid coupling device comprising:
a main body defining a fluid flow path extending along a longitudinal axis, the main body comprising:
a front face,
a first projection extending in a direction of the longitudinal axis, and
a first projection receptacle;
a seal coupled to the main body between the first projection and the first projection receptacle and around the longitudinal axis, a portion of the seal protruding from the front face of the main body;
a removable membrane releasably attached to the front face of the main body and covering the portion of the seal protruding from the front face of the main body; and
a protective cover removably engaged with the main body and comprising: (i) a second projection receptacle releasably engaged with the first projection of the main body and (ii) a second projection releasably engaged with the first projection receptacle of the main body,
wherein the protective cover is: (i) structured without a fluid flow path and (ii) required to be removed from engagement with the main body to allow the fluid coupling device to be operatively mated with another fluid handling device.
2. The fluid coupling device of claim 1 , wherein the seal comprises a circular projection that has a triangular cross-sectional shape, and wherein the circular projection extends parallel to the longitudinal axis.
3. The fluid coupling device of claim 1 , wherein the seal comprises two annular concavities defined by the outer surface of the seal.
4. The fluid coupling device of claim 1 , wherein the seal includes a portion having an hourglass cross-sectional shape.
5. The fluid coupling device of claim 1 , wherein the fluid coupling device is genderless such that two of the fluid coupling devices can be coupled to each other.
6. The fluid coupling device of claim 1 , wherein the protective cover includes a pull ring.
7. The fluid coupling device of claim 6 , wherein the pull ring defines an opening configured to receive a finger.
8. The fluid coupling device of claim 7 , wherein the protective cover includes a membrane receiver portion that holds and protects a portion of the removable membrane.
9. The fluid coupling device of claim 1 , wherein the protective cover includes a membrane receiver portion that holds and protects a portion of the removable membrane.
