摘要:
A flow control valve for medical liquid is disclosed. The valve has a housing including an inlet, an outlet, and a flow path therebetween. A plurality of flow restrictors are located in the flow path to define a plurality of flow streams of differing flow rates. A flow control member is disposed in the flow path, and has a plurality of discrete apertures in a first region or plane and at least one aperture in a second region or plane spaced apart from the first plane. The flow control member is rotationally movable and defines an annular gap and radial groove which provide fluid communication between the different planes and the outlet regardless of the orientation of the flow control member. The flow control member may be rotated between a first position in which one of the plurality of apertures in the first plane is in communication with one of the flow streams to define a first flow rate through the valve, and a second position in which one of the at least one aperture in the second plane is in communication with a different one of the flow streams to define a second flow rate through the valve different from the first flow rate.
