Abstract
The quick connect/disconnect tubing adapter is used for capturing a tubing within the adapter in a generally sterile manner. The adapter comprises two mating body portions which have passageways for receiving a tubing end portion. A tubing is received in and fixed in the passageways and is adapted to contract around the tubing end portion when the body portions are pulled away from each other. Additionally, a locking mechanism is provided for releasably locking the body portions together in a pulled apart position with the tubing end portion captured in the tubing.
Claims14
A quick connect/disconnect tubing adapter comprising:
- an outer body portion having an elliptically-shaped cavity therein and a bore extending therethrough from the body of said elliptically-shaped cavity to one end of said outer portion;
- an inner body portion, at least a part of which is ellipsoid-shaped and received within said elliptically-shaped cavity, and a part of which extends outwardly from the other end of said outer body portion;
- said inner body portion having a lumen of a diameter generally equal to the diameter of said bore in said outer body portion;
- an elastomeric tubing extending within said lumen inside said inner body portion and within said bore in said outer body portion;
- said tubing being fixed in said lumen of said part of said inner body portion extending outwardly of said outer body portion and in said bore of said outer body portion;
- said tubing having a lumen for receiving a smaller diameter tubing end portion therein;
- said body portions being longitudinally movable away from each other a limited distance to cause said tubing to stretch and contract radially inwardly to capture said tubing end portion therein in a capture position of said body portion;
- and
- said body portions having means for frictionally locking said body positions in said capture position.
A quick connect/disconnect tubing adapter for capturing a tubing end portion within the adapter in a generally sterile manner, said adapter comprising:
- two elongate mating body portions, one body portion having an out-of-round in cross-section cavity therein and the other body portion having a similar, but smaller, out-of-round in cross-section outer surface along a portion of the length thereof which is received in said cavity;
- passage means in both said body portions of receiving a tubing end portion in both said body portions;
- gripping means extending between said body portions and around a tubing end portion received therein;
- said body portions being movable away from each other to cause said gripping means to grip a tubing end portion received therein;
- and
- said out-of-round in cross-section cavity in said one body portion and said out-of-round in cross-section outer surface portion of said other body portion defining rotatable means for releasably and frictionally locking said moved apart body portions together upon relative rotation between said body portions with the tubing end portion captured in said gripping means.
