Device for controlling the rate of flow of a fluid

摘要

A device (1) for controlling the rate of flow of a fluid such as fluid which is diverted from a part of a human or animal body. The device comprises: an inlet (2); an outlet (4); and a resistance member (6), operatively connected to the inlet (2) and the outlet (4), the resistance member (6) comprising: a first plate (8), a surface of which comprises a groove which defines a resistance flow channel, an entry of the flow channel being in fluid communication with the inlet (2) and an exit of the flow channel being in fluid communication with the outlet (4); and a second plate (12), the second plate being held in abutment with the grooved surface of the first plate (8) so as to define a resistance (tube 14).

主权项

1. A device for subcutaneous implantation within a human or animal body to divert fluid in a selectively controllable manner from a first part of the human or animal body to a second part thereof, the device comprising:
an inlet adapted to communicate with a first part of a human or animal body; an outlet adapted to communicate with a second part of the human or animal body; and a resistance member that communicates with the inlet and the outlet, the resistance member including: a first plate including a surface having a groove; a second plate that abuts the surface of the first plate and cooperates with the groove to define a resistance flow channel having an entry that communicates with the inlet and at least first and second exits that define different effective lengths of the resistance flow channel from the entry; and a rotor supported on one the first plate or the second plate for rotation between at least a first rotational position, wherein communication is provided between the first exit of the resistance flow channel and the outlet, and a second rotational position that position, wherein communication is provided between the second exit of the resistance flow channel and the outlet, the rotor being magnetically excitable so that it can be selectively rotated between the first and second rotational positions by a magnet located proximate the device.
