Abstract

A method of extending the therapeutic duration of a thermal therapy product is disclosed. The method includes selecting a thermal therapy product to provide a benefit to a user, selecting a phase change material, incorporating the phase change material into a flexible thermal therapy sleeve, and placing the thermal therapy product into the thermal therapy sleeve.

Claims (35)

1. A method of extending the therapeutic duration of a thermal therapy product comprising:

selecting a thermal therapy product;

selecting a phase change material;

incorporating the phase change material into a flexible thermal therapy sleeve, the sleeve having an opening through which the thermal therapy product may be inserted and removed; and

placing the thermal therapy product into the thermal therapy sleeve.

2. The method of claim 1 , further comprising activating the thermal therapy product.

3. The method of claim 1 , further comprising removing the thermal therapy product from the sleeve for disposal, regeneration, or replacement of the product.

4. The method of claim 1 , comprising selecting the product to be reusable.

5. The method of claim 1 , comprising selecting the product to be gel-based.

6. The method of claim 1 , comprising selecting the product to be disposable.

7. The method of claim 1 , comprising selecting the product to provide a heat benefit.

8. The method of claim 1 , comprising selecting the product to be a chemical heat pack.

9. The method of claim 8 , wherein the chemical heat pack comprises a first compartment and a second compartment separated by a membrane, where the first compartment contains a solute and the second compartment contains a solvent, wherein the rupturing of the membrane causes the combination of the solute and solvent and produces an exothermic reaction.

10. The method of claim 1 , comprising selecting the phase change material to have a transition temperature of from about 35° C. to about 65° C.

11. The method of claim 1 , comprising selecting the phase change material from the group consisting of n-tridecane, n-retradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nonadecane, n-eicosane, and a combination thereof.

12. The method of claim 1 , comprising selecting the product to provide a cold benefit.

13. The method of claim 1 , comprising selecting the product to include a chemical cold pack.

14. The method of claim 13 , wherein the chemical cold pack comprises a first compartment and a second compartment separated by a membrane, where the first compartment contains a solute and the second compartment contains a solvent, wherein the rupturing of the membrane causes the combination of the solute and solvent and produces an endothermic reaction.

15. The method of claim 1 , comprising selecting the phase change material to have a transition temperature of from about −10° C. to about 40° C.

16. The method of claim 1 , comprising selecting the phase change material from the group consisting of n-eicosane, n-hemeicosane, n-docosane, n-tricosane, n-tetracosane, n-pentacosane, n-hexacosane, n-heptacosane, n-octacosane, and a combination thereof.

17. A method of making a thermal therapy system having an extended therapeutic duration comprising:

selecting a solute and a solvent such that the mixing of the solute and the solvent results in an endothermic or exothermic reaction;

depositing the solute and the solvent in a pack, the pack divided into a first compartment and a second compartment by a membrane, where the first compartment contains the solute and the second compartment contains the solvent, wherein the rupturing of the membrane causes the mixing of the solute and solvent;

selecting a phase change material;

incorporating the phase change material into a flexible thermal therapy sleeve, the sleeve having an opening through which the pack may be inserted and removed;

activating the pack; and

placing the pack into the thermal therapy sleeve.

18. The method of claim 17 , comprising selecting the phase change material to have a transition temperature of from about −10° C. to about 65° C.

19. A method of making a thermal therapy system having an extended therapeutic duration comprising:

providing a reusable heat or cold thermal therapy product;

selecting a phase change material;

incorporating the phase change material into a flexible thermal therapy sleeve, the sleeve having an opening through which the product may be inserted and removed;

providing an energy source to activate the product; and

placing the product into the thermal therapy sleeve.

20. The method of claim 19 , comprising selecting the phase change material to have a transition temperature of from about −10° C. to about 65° C.
