Abstract
A housing includes a cavity portion and a cover portion configured for rotary motion. The cover portion can include a receiver port configured to engage with a fitting configured for coupling to an end of a first tube. At a first alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a first retention cleat. At a second alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a fluid coupler. At a third alignment position of the cavity portion relative to the cover portion, the fitting is aligned with a second cap.
Claims18
A system comprising:
- a housing having a cavity portion and a cover portion, the cover portion configured for rotary motion relative to the cavity portion, the cover portion having a receiver port configured to engage with a fitting configured for coupling to an end of a first tube, the receiver port and fitting having an insertion limiter and having a key and corresponding keyway, the insertion limiter configured to limit a longitudinal engagement depth of the fitting relative to the receiver port and the key and keyway configured to allow first limited rotation of the fitting relative to the receiver port for a first depth of insertion and configured to allow second limited rotation of the fitting relative to the receiver port for a second depth of insertion;
- wherein, at a first alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a first retention cleat, the first retention cleat configured to engage with a lug of the first cap, the first cap coupled to the fitting, in which the lug and the first retention cleat are configured to disengage the first cap from the fitting with longitudinal movement of the fitting relative to the receiver port;
- wherein at a second alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a fluid coupler, the fluid coupler configured to engage with the fitting and provide a fluid coupling between a lumen of the fitting and a lumen of the fluid coupler;
- and
- wherein at a third alignment position of the cavity portion relative to the cover portion, the fitting is aligned with a second cap, the second cap configured to engage with the lumen of the fitting and provide a leak resistant closure of the lumen of the fitting.
A method comprising:
- forming a housing having a first portion and a second portion, the first portion having a receiver port configured to receive a fitting and to receive a first cap coupled to the fitting, the fitting having a fitting lumen, the first portion and the second portion configured for independent rotation and having a first alignment position, a second alignment position, and a third alignment position, wherein the first alignment position, the second alignment position, and the third alignment position differ;
- forming a first cleat on the housing to engage with a first lug of the first cap corresponding to the first alignment position, the first cleat and the first lug configured to selectively engage and configured to decouple the first cap and the fitting with a first movement of the fitting relative to the receiver port;
- forming a fluid coupling on the housing corresponding to the second alignment position, the fluid coupling having a coupling lumen configured to engage with the fitting lumen;
- and
- coupling a second cap to the housing corresponding to the third alignment position, the second cap having a second lug configured to selectively engage with a second cleat of the housing, the second cap configured to disengage from the housing with a second movement of the fitting relative to the receiver port.
