Compression device for the limb
View Patent ↗The invention provides a compression device for the limb of a mobile patient. The device includes an inflatable sleeve adapted to surround the limb; a conduit attached to the sleeve for delivering fluid to the sleeve; and a portable, wearable controller attached to the conduit that generates and controls the flow of fluid in the device.
1. A compression device for the limb of a mobile patient comprising:
an inflatable sleeve adapted to surround the limb;
a conduit attached to said sleeve for delivering fluid to said sleeve; and
a portable, wearable controller attached to said conduit that generates and controls the flow of fluid in the device, the controller comprising a microprocessor control system and a pump, wherein the device is configured to provide compression to the limb using the inflatable sleeve and configured to provide a patient controlled silent mode, wherein the device applies compression with the pump disabled when in the silent mode and the device does not operate the pump to compensate for a pressure fall after a period of time when in the silent mode, and wherein the patient can switch the device out of silent mode and reactivate the pump.
2. The compression device as claimed in claim 1 , wherein said sleeve includes one or more individually inflatable cells.
3. The compression device as claimed in claim 1 , wherein said sleeve includes a leg cuff and a foot cuff.
4. The compression device as claimed in claim 3 , wherein said leg cuff includes at least three cells.
5. The compression device as claimed in claim 1 , wherein said controller is battery operated.
6. The compression device as claimed in claim 2 , wherein each cell is monitored by a sensor.
7. The compression device as claimed in claim 4 , wherein said cells include a gaiter cell, adapted to wrap around the lower limb in the region closest to the ankle, a mid-calf cell, adapted to wrap around the lower limb above the region occupied by the gaiter cell and an upper cell adapted to wrap around the lower limb in the region between the mid-calf cell and the knee.
8. The compression device as claimed in claim 4 , wherein said cells are pressurized to the same or different predetermined pressures.
9. A compression device for the limb of a mobile patient comprising:
an inflatable sleeve adapted to surround the limb;
a conduit coupled to said sleeve for delivering fluid to said sleeve; and
a portable, wearable controller coupled to said conduit that generates and controls the flow of fluid, the controller comprising a microprocessor control system and a pump, wherein the controller is configured to allow a patient to selectively operate the device in dynamic compression in which the pressure is monitored during use to provide the dynamic compression and maintain a preset compression profile on the limb and operate the device in a silent mode, wherein the device applies compression with the pump disabled when in the silent mode and the device does not operate the pump to compensate for a pressure fall after a period of time when in the silent mode.
10. The compression device as claimed in claim 9 , wherein the device is configured to allow the patient to switch the device out of silent mode and reactivate the pump.
11. The compression device as claimed in claim 9 , wherein said sleeve includes one or more individually inflatable cells.
12. The compression device as claimed in claim 9 , wherein said sleeve includes a leg cuff and a foot cuff.
13. The compression device as claimed in claim 9 , wherein said controller is battery operated.
14. The compression device as claimed in claim 11 , wherein each cell is monitored by a sensor.
15. A compression device for the limb of a mobile patient comprising:
an inflatable sleeve adapted to surround the limb;
a conduit coupled to said sleeve for delivering fluid to said sleeve; and
a portable, wearable controller coupled to said conduit that generates and controls the flow of fluid, the controller comprising a microprocessor control system and a pump, wherein the device is configured to provide compression to the limb using the inflatable sleeve and the device is configured to provide a patient controlled silent mode, wherein the pump is disabled and all valves are kept closed when in the silent mode.
16. The compression device as claimed in claim 15 , wherein the controller is configured to allow a patient to selectively operate the device in dynamic compression in which the pressure is monitored during use to provide the dynamic compression and maintain a preset compression profile on the limb or operate the device in the silent mode in which the device applies compression but if the pressure falls after a period of time the device does not operate the pump to compensate.
17. The compression device as claimed in claim 15 , wherein said sleeve includes one or more individually inflatable cells.
18. The compression device as claimed in claim 15 , wherein said sleeve includes a leg cuff and a foot cuff.
19. The compression device as claimed in claim 15 , wherein said controller is battery operated.
20. The compression device as claimed in claim 15 , wherein each cell is monitored by a sensor.
