MEDICAL VALVE ASSEMBLY

摘要

2071514 9116092 PCTABS00007 A medical valve assembly is described in which the valve assembly has a female luer lock portion (14) on an inlet end of the device and a male luer lock portion (18) on the outlet portion (26) of the valve. A movable piston (8) seals the inlet portion (36) of the valve from the outlet portion when the piston is in the closed position. When a syringe is attached to the inlet portion of the valve assembly, the piston is displaced in a manner that unseals a fluid channel inlet. This connects the end of the syringe to the fluid channel which is connected, at its outlet end, to a catheter or other device connected to a patient. Thus, medication can be introduced to, or fluids aspirated from, a patient's bloodstream without the use of a syringe having a needle.
