Syringe delivery tip adapted to provide controlled flow rate

摘要

A delivery tip configured to engage a syringe delivery device includes a hub, a cannula attached to the hub, and structure configured to regulate the fluid flow rate through the delivery tip. The hub includes a passage disposed there through. The cannula includes a lumen formed therethrough in communication with the hub passage. A restriction portion is formed in the hub passage. The restriction portion is such that it forms a minimum diameter in the hub passage that is smaller than the minimum diameter of the lumen. As such, the fluid rate is primarily determined by the size of the restriction portion rather than the diameter of the cannula lumen.
