Abstract

A control unit coupled to a thermal therapy device, a compression therapy device and DVT therapy devices is provided. The thermal therapy device includes a fluid bladder for delivering hot and/or cold therapy to a patient. The compression therapy device includes an gas bladder for providing compression to a patient. The DVT therapy devices provide pulsed compression in coordination with the compression therapy device.

Claims (23)

1. A method for addressing aspects of deep vein thrombosis (DVT) in a patient utilizing compression applied to the patient, the method comprising:

providing a control unit adapted to thermally condition a heat transfer fluid to a temperature within a range of about 37° F. and about 105° F., and adapted to provide compressed gas at a pressure of at least 25 mmHg greater than an ambient atmospheric pressure;

providing a thermal compression device for securement to the patient and adapted to receive at least a portion of the heat transfer fluid and at least a portion of the compressed gas from the control unit;

providing first and second DVT compression devices for securement to the patient, each being adapted to receive at least a portion of the compressed gas from the control unit;

coupling the thermal compression device, the first DVT compression device, and the second DVT compression device to the control unit; and

programming the control unit to coordinate distribution of the compressed gas between the thermal compression device and the first and the second DVT compression devices so that the thermal compression device receives compressed gas at a different time than when the first DVT compression device receives compressed gas.

2. The method of claim 1 , wherein the first and the second DVT compression devices are secured to a left ankle and a right ankle of the patient.

3. The method of claim 1 , wherein the thermal compression device is secured to a knee of the patient.

4. The method of claim 1 , and further comprising:

monitoring a condition of the patient in at least partial dependence on the compressed gas being provided to the thermal compression device.

5. The method of claim 4 , wherein the compressed gas provided to the thermal compression device is varied based on the conditioned monitored.

6. The method of claim 1 , wherein the heat transfer fluid is heated from about 49° F. to about 105° F. and applied to a skin area of the patient.

7. The method of claim 1 , wherein the heat transfer fluid is cooled from about 105° F. to about 49° F. and applied to a skin area of the patient.

8. The method of claim 1 , wherein the heat transfer fluid is cooled from an ambient temperature of about 77° F. to a temperature of about 37° F. within a 90 minute period.

9. The method of claim 1 , wherein the control unit is adapted to provide the compressed gas at a pressure in the range of about 0 to about 120 mm Hg.

10. The method of claim 1 , wherein compressed gas is provided to the first DVT compression device during a first pulse for a user-specified length of time and compressed gas is provided to the second DVT compression device during a second pulse for user-specified length of time.

11. The method of claim 1 , comprising providing the compressed gas to the thermal compression device, the first DVT compression device, and the second DVT compression device at one or more user-specified pressures.

12. The method of claim 1 , comprising applying the first DVT compression device to a first foot of the patient and applying the second DVT compression device to a second foot of the patient.

13. The method of claim 1 , comprising applying compressed gas to three or more bladders within the thermal compression device.

14. The method of claim 13 , comprising:

providing a first pulse of compressed gas to a first bladder of the thermal compression device;

providing a second pulse of compressed gas to a second bladder of the thermal compression device; and

providing a third pulse of compressed gas to a third bladder of the thermal compression device.
