Abstract

A device has four fundamental components: an enclosure, a soft seal, a vacuum system and a thermal energy system having a thermal energy contacting element. The device provides thermal energy therapy and negative pressure therapy device simultaneously and/or in conjunction to a patient. The device has a thermal energy system that is more efficient in thermal energy transfer and the soft seal decreases tissue interface pressure to obtain the desired soft seal effect.

Claims

1. A thermal energy and negative pressure therapies device comprising (1) an enclosure having an opening to receive a portion of a patient'"'"'s body that contains a venous plexus area, (2) a vacuum system that creates a negative pressure in the enclosure, (3) a soft seal to maintain the negative pressure in the enclosure, and (4) a thermal energy system having a thermal energy contacting element so the patient'"'"'s venous plexus area contacts the thermal energy contacting element;

the thermal energy contacting element is selected from the group consisting of

(a) a metallic thermal energy transfer unit that receives a fluid and/or contains resistors when the soft seal has a bladder seal positioned in the interior of the enclosure and the metallic thermal energy transfer unit contacts the patient'"'"'s venous plexus area and the bladder seal contacts the patient'"'"'s body portion on the opposite side of the venous plexus area,

(b) a light source that radiates heat from within the enclosure toward the patient'"'"'s venous plexus area;

(c) a cold source positioned within the enclosure and extracts thermal energy from the patient'"'"'s venous plexus area;

(d) a convective fitting object positioned on the patient'"'"'s venous plexus area,

(e) conductive beads extending from and interconnected to a conductive plate, and

(f) a thermal block in combination with a plurality of weighted slip pins.

2. The device of claim 1 wherein the soft seal is selected from the group consisting of a bladder seal positioned in the interior of the enclosure and the bladder seal and the thermal energy contacting element are on opposite sides of the patient'"'"'s venous plexus area;

an inflatable bladder positioned at or near the enclosure'"'"'s opening; and

a first sheet and a second sheet interconnected to each other with openings therein.

3. The device of claim 1 wherein when the thermal energy contacting element is the light source, the light source is selected from the group consisting of a light source that radiates heat having a narrow band of non-ionizing light between 500 to 2000 nm and a light source that radiates heat having a broad band of non-ionizing light between 500 to 2000 nm.

4. The device of claim 3 wherein the patient'"'"'s body in the enclosure is covered with a form fitting material, and negative pressure is between the form fitting material and the patient'"'"'s body.

5. The device of claim 3 wherein the enclosure has a mezzanine layer that separates the enclosure into a first section that receives the patient'"'"'s venous plexus area and a second area that contains the thermal energy contacting element.

6. The device of claim 5 wherein the mezzanine layer has thermocouple devices interconnected to the thermal energy system to control the thermal energy contacting element.

7. The device of claim 4 wherein the form fitting material has thermocouple devices interconnected to the thermal energy system to control the thermal energy contacting element.

8. The device of claim 1 wherein the convective fitting object has negative pressure between the convective fitting object and the patient'"'"'s body.

9. The device of claim 1 wherein the conductive plate provides thermal energy selected from the group consisting of thermal energy having a temperature (a) above the patient'"'"'s body core temperature, and (b) below the patient'"'"'s body core temperature.

10. The device of claim 1 wherein the thermal block provides thermal energy selected from the group consisting of thermal energy having temperature (a) above the patient'"'"'s body core temperature, and (b) below the patient'"'"'s body core temperature.

11. A thermal energy and negative pressure therapies device comprising an enclosure having an opening to receive a portion of a patient'"'"'s body that contains a venous plexus area, (2) a vacuum system that creates a negative pressure in the enclosure, (3) a soft seal to maintain the negative pressure in the enclosure, and (4) a thermal energy system having a thermal energy contacting element so the patient'"'"'s venous plexus area contacts the thermal energy contacting element;

the soft seal is selected from the group consisting of a bladder seal positioned in the interior of the enclosure and the bladder seal and the thermal energy contacting element are on opposite sides of the patient'"'"'s venous plexus area;

an inflatable bladder positioned at or near the enclosure'"'"'s opening; and

a first sheet and a second sheet interconnected to each other with openings therein.

12. The device of claim 11 wherein the thermal energy contacting element is selected from the group consisting of
