Abstract

This invention is a safety valve (1) for use with infusion devices (6), having a highly sensitive structure (2) to allow the passage of liquids, even at low pressure and very low flow rates, in one direction, while at the same time it stops the blood flow, even at low pressure, in the opposite direction.
