Abstract

A compression treatment system is provided that includes a first bladder supported about a limb. A second bladder is supported about the limb. The bladders are in fluid communication with a fluid source and the bladders are inflated such that the first bladder is inflated for a first time period and the second bladder is inflated for a second time period. The second time period is initiated within the first time period. A single pressure sensor communicates with the first bladder and the second bladder.

a pneumatic control circuit located at a controller housed separately from the inflatable bladders, the pneumatic control circuit including the controller, a single pressure sensor, a single check valve, the fluid source and a plural of solenoid valves, the single pressure sensor located between the fluid source and solenoid valves and communicating with the first bladder and the second bladder, and the single check valve operably connected to the fluid source and located between the fluid source and solenoid valves, wherein the single check valve prevents leakage out of the first bladder, and the single pressure sensor measures bladder pressure in cooperation with the controller to calculate venous refill time at the first bladder.

2. A compression treatment system as recited in claim 1, further comprising the controller that communicates with the pressurized fluid source and the pressure sensor, the controller being configured to monitor and regulate pressure in the bladders.

3. A compression treatment system as recited in claim 2, wherein the controller includes separate valves that regulate inflation of the bladders.

4. A compression treatment system as recited in claim 1, wherein the controller is disposed with the housing that is portable.

5. A compression treatment system as recited in claim 1, wherein the housing includes a plurality of ports connectable to a plurality of bladders.

6. A compression treatment system as recited in claim 5, wherein the single pressure sensor monitors pressure at each of the plurality of ports to determine if a bladder is connected thereto and sends a representative signal to the controller.

7. A compression treatment system as recited in claim 1, wherein the pressure sensor is configured to monitor pressure of each of the bladders.

8. A compression treatment system as recited in claim 1, further comprising a foot bladder communicating with the pressure sensor.

9. A compression treatment system as recited in claim 1, wherein the pressurized fluid source alternately inflates the bladders disposed about the first limb and the bladders disposed about the second limb.

10. A compression treatment system as recited in claim 1, wherein the check valve operates without an electrical signal to the controller.

11. A compression treatment system comprising:

a first bladder supported about a limb;

a second bladder supported about the limb, the first and second bladders being in fluid communication with a fluid source and the first and second bladders being inflated such that the first bladder is inflated for a first time period and the second bladder is inflated for a second time period, the second time period being initiated within the first time period;

a third bladder supported about a foot, the third bladder being in fluid communication with the fluid source; and

a pneumatic control circuit located at a controller housed separately from the inflatable bladders, the pneumatic control circuit including the controller, a single pressure sensor, a single check valve, the fluid source and a plurality of solenoid valves,

the single pressure sensor, located between the fluid source and solenoid valves, communicating with the bladders and the check valve operably connected to the fluid source and located between the fluid source and solenoid valves, wherein the single check valve prevents leakage out of a measuring bladder, the single pressure sensor measures bladder pressure in cooperation with the controller to calculate venous refill time at the measured bladder.

12. A compression treatment system as recited in claim 11, wherein the pressurized fluid source alternately inflates the bladders disposed about the limb and the bladder disposed about the foot.

13. A compression treatment system as recited in claim 12, wherein the controller is disposed with a housing that is portable.

14. A compression treatment system as recited in claim 12, wherein the controller includes separate valves that regulate inflation of the bladders.

15. A compression treatment system as recited in claim 11, further comprising a controller that communicates with the pressurized fluid source and the single pressure sensor, the controller being configured to monitor and regulate pressure in the bladders.

16. A compression treatment system as recited in claim 11, wherein the single pressure sensor is configured to monitor pressure of each of the bladders.

17. A compression treatment system as recited in claim 11, wherein the check valve operates without an electrical signal to the controller.

18. A compression treatment system comprising:

a first plurality of bladders supported about a first limb;

a second plurality of bladders supported about a second limb, the bladders being in fluid communication with a fluid source and the bladders being inflated such that;

a first bladder of the first plurality of bladders is inflated for a first time period and a second bladder of the first plurality of bladders is inflated for a second time period, the second time period being initiated within the first time period, and
