43 results about "Rapid infusion" patented technology

A catheter assembly is provided having a conical diffuser tip for use in rapid infusion procedures. The conical diffuser tip provides a flared opening whereby the velocity of an infusant is decreased as the infusant travels through the catheter tip and exits into the vascular system of a patient. This decrease in velocity proportionately reduces the backpressure and/or recoil force of the catheter assembly thereby permitting the use of higher infusion rates. The catheter tip is introduced into the vasculature of a patient via a splittable introducer needle.
