Infusion device for driving valve intravenous fluids.

摘要

A valve (10) includes a cannula BASICAMENTE RIGID (18) and an element VALVE FOR COMMUNICATION CONNECTED WITH OPERATIONAL cannula (18). VALVULAR ELEMENT (16) is formed from a substantially resistant material and is movable relative to the cannula (18) between a first closed position and a second open position. Cannula (18) COOPERATE FOR EXTENSION THROUGH THE ELEMENT VALVE (16) during movement from the first position CLOSED TO THE SECOND POSITION OPEN TO ESTABLISH A flow path of fluid through the cannula (18) and the ELEMENT VALVE (16). Also provided a sealing element (50) acts independently of the circulation of fluid in the flow path FLUID AND INDEPENDENT OF ANY ELEMENT USED WITH VALVE (10) to provide automatically positive sealing an opening (76,78,78B) ON THE VALVE ELEMENT WHEN STANDING IN THE FIRST closed position, the cannula (18) extends through the opening (76,78,78B) during movement VALVULAR ELEMENT (16) .
