PULSATILE OR RESONATING FLUSH SYRINGE

Abstract:

A flush syringe for use in maintaining intravenous catheters, which can more efficiently and effectively flush catheters by providing a pulsating, pulsatile, and/or pulsative flow of fluid that can be produced using the momentum of the moving fluid itself. A steady force applied to the plunger while flushing can provide a pulsating flow of fluid to a catheter.
