Flow control device

A device adapted to divert fluid from a part of a human or animal body in a controlled manner, the device comprising:

• an inlet;
• an outlet;
• and
• a resistance member, operatively connected to the inlet and the outlet, the resistance member comprising:
• a first plate portion, a surface of which comprises a groove;
• a second plate portion, a surface of which is held in abutment with the groove of the first plate portion so as to define a resistance flow channel extending between an inner diameter of the first and second plate portions and an outer diameter of the first and second plate portions, the flow channel comprising a plurality of arcs arranged in flow series, each arc radially extending between the inner and outer diameters of the first and second plate portions, and;
• a selection means operable to interconnect a selected number of the arcs to the inlet and outlet, thereby varying the effective length of the resistance flow channel progressively over the whole range of resistance defined by the total length of the resistance flow channel.
