One-time priming iv infusion extension set

Abstract

A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.
