Abstract: A blunt needle connector described herein is used for transferring fluids or medication through compatible injection ports associated with primary, secondary and central lines during intravenous therapy applications. The needle connector provides needle stick protection without recessing the needle in the shield. This feature allows the end-user to better align the injection port to the needle connector and lock the needle to the injection port to eliminate line disconnects. The blunt needle connector also provides for an audible or tactile indication that the latch is secured to the intravenous fitting. This feature makes it easy to distinguish between the open or unlocked and closed or locked position of the latch. In addition, the blunt needle connector provides attachment to an intravenous line without the twisting of the line that is associated with a threaded connector.

Abstract: A system for coupling a vascular overflow graft or cannula to a heart pump. A pump pipe outlet is provided with an external tapered surface which receives the end of a compressible cannula. An annular compression ring with a tapered internal bore surface is arranged about the cannula with the tapered internal surface in a facing relationship to the external tapered surface. The angle of inclination of the tapered surfaces is converging such that the spacing between the tapered surfaces decreases from one end of the external tapered surface to the other end thereby providing a clamping action of the tapered surface on a cannula which increases as a function of the length of cannula segment between the tapered surfaces. The annular compression ring is disposed within a tubular locking nut which threadedly couples to the pump and provides a compression force for urging the annular ring onto the cannula between the tapered surfaces. The nut has a threaded connection to the pump body.
