Patent ID: 8146592

Claim:
An apparatus for connection to a source of pressurized fluid and for connection to a cannula, the apparatus comprising: a revolved body having a first end, a second end, a central longitudinal axis, an input adapted to be coupled to the source of pressurized fluid, an output configured to be coupled to the cannula, and a fluid passage configured to connect the input to the output; and a flow selector positioned between the input and the output, the flow selector being rotatably coupled to the revolved body at a location between the first end and the second end of the revolved body, the flow selector being actuatable from the exterior of the revolved body and positioned such that an axis of rotation of the flow selector is parallel to and offset from the central longitudinal axis of the revolved body, wherein the flow selector includes a first fluid passage configured to restrict the flow of fluid to a first flow rate from the input to the output when the first fluid passage is aligned with the fluid passage which connects the input and the output.
