An apparatus for applying pressure to a body part, the apparatus comprising:
- a sleeve configured to at least partially surround a body part, the sleeve comprising a plurality of inflatable sections;
- and
- a pump assembly, the pump assembly comprising:
- a pump;
- and
- a plurality of channels, each channel configured to be in fluid communication with the pump and a respective inflatable section, wherein each channel comprises:
- a supply valve configured to regulate air entering the respective inflatable section;
- and
- a release valve configured to regulate air exiting the respective inflatable section.
A pump assembly for applying pressure to a body part, the pump assembly comprising:
- a pump;
- and
- a set of isolated pressure systems, each isolated pressure system comprising:
- a port configured to fluidly connect to a respective chamber;
- a positive-flow valve in fluid communication with the pump and configured to provide positive pressure to the port;
- and
- a negative-flow valve in fluid communication with the pump and configured to provide negative pressure to the port.
A method of applying pressure to a body part, the method comprising:
- providing a pump configured to generate air pressure;
- providing a sleeve configured to at least partially surround a body part, the sleeve comprising a plurality of inflatable chambers configured to be in fluid communication with the pump;
- providing pathways between a supply valve and a return valve to each inflatable chamber of the plurality of inflatable chambers;
- and
- varying the air pressure within each inflatable chamber through operation of the pump, the supply valves, and the return valves.
