Abstract:
A device for creating a blunt interface between liquids delivered using a cannula having a lumen and a hub with a reservoir disposed therein, the device comprising:a body having a proximal end configured for connection to a syringe and a distal end opposite the proximal end configured to be attached to the cannula hub; a tapered lumen extending through the body from the proximal end to the distal end, the tapered lumen having a first diameter at the proximal end and a second smaller diameter at the distal end; and a tube which extends from the distal end of the body to the lumen of the cannula when the distal end of the body is attached to the cannula hub such that liquid is delivered directly to the lumen of the cannula bypassing the reservoir in the cannula hub.
