Abstract:
1. A catheter assembly comprising: a catheter hub defining first and second fluid channels and including a mounting collar having first and second longitudinal grooves defining locking shelves on the catheter hub; first and second hypo tubes extending from the catheter hub member for passage of fluids, the first hypo tube communicating with the first fluid channel and the second hypo tube communicating with the second fluid channel; a catheter including first and second catheter lumens, and defining leading and trailing ends, the catheter being mountable to the catheter hub with the first and second hypo tubes received within the first and second catheter lumens at the trailing end of the catheter; a locking sleeve slidably mounted about the catheter, the locking sleeve including a pair of locking tabs with locking detents, the locking tabs being adapted for reception within the first and second longitudinal grooves with the locking detents engaging the locking shelves to secure the locking sleeve to the catheter hub; and a compressible ring positioned within the locking sleeve, the compressible ring adapted to compress the catheter against the hypo tubes during securement of the locking sleeve to the catheter hub, wherein the compressible ring includes a plurality of deflectable elements arranged in annular spaced relation, the deflectable elements being deflected inwardly during securement of the locking sleeve to the catheter hub to engage the trailing end of the catheter.
