Abstract:
1. An apparatus for connecting multi-lumen conduits, each multi-lumen conduit having a primary lumen and at least one ancillary lumen, the apparatus comprising: a conduit adapter having: a housing having a first end and a second end, a tubular connector positioned within the housing and having a bore extending along the longitudinal axis of the tubular connector, wherein a first end of the tubular connector is configured to receive a first multi-lumen conduit, and a support member connecting the housing and the tubular connector, wherein the support member is formed with at least one aperture therethrough; a conduit collar having a first end and a second end and having an internal bore, the first end being sized for insertion into the second end of the housing and rotational within the housing, the second end of the conduit collar being configured to receive a second multi-lumen conduit within the internal bore of the conduit collar; wherein the tubular connector is configured to rotationally engage the primary lumen of the second multi-lumen conduit while permitting fluid communication between the primary lumens of the first end and second multi-lumen conduits via the bore of the tubular connector; wherein the support member is configured to permit fluid communication between the at least one ancillary lumen of the first and second multi-lumen conduits via the at least one aperture; wherein the bore of the tubular connector is configured to maintain fluid communication between the primary lumens and the at least one aperture maintains fluid communication between the ancillary lumens when the first and second multi-lumen conduits are subjected to relative rotation between them; wherein the conduit adapter is secured to a bulkhead; a bearing collar rigidly secured to the bulkhead; a first shaft member having a first end rigidly secured to the conduit collar, and a second end; and a bearing assembly fixed on the second end of the first shaft member and rigidly positioned within the bearing collar whereby the conduit collar and the second multi-lumen conduit are free to rotate within the bearing collar relative to the bulkhead.
