发明名称 Medical valve
摘要 A medical valve includes a housing having an inlet end and a fluid outlet end, and a flexible elastomeric plug defining an upper face. At least a portion of the plug is moveable along the housing in response to the application of a male luer against the upper face. The plug defines an elastomeric flow path within it. The flow path defines a distal aperture. The luer displaces at least a portion of the elastomeric plug in a first direction along the housing and the displacing force distorts the plug increasing the volume of the flow path within the plug and enlarging at least a portion of the fluid flow path between the upper face of the plug and the outlet end. When the male luer is withdrawn the plug returns to its original shape and thereby elastically decreases the volume of the flow path, to cause at least a portion of residual fluid in the flow path to be expelled through the distal aperture so that at least a portion of the residual fluid within the elastomeric plug is expelled in a different direction than the direction of luer withdrawal. In one embodiment the flow path exits the plug along its lateral wall.
