## Abstract

A temperature treatment apparatus includes a body made from a flexible and expandable material for attachment to a predetermined region of the human body requiring treatment with the body having a space formed therein, and a temperature radiating element shaped to be received within the space of the body and being configured to have a soft and malleable shape profile to apply temperature treatment to the predetermined region of the human body. The temperature radiating element includes an inner pouch containing a first phase change material that is able to be inserted within an outer pouch having a second phase change material, so that, upon insertion, the inner pouch is substantially encapsulated within the second phase change material of the outer pouch.

## Claims

### Claim 1

A temperature treatment apparatus, comprising:
a body made from a flexible and expandable material for attachment to a predetermined region of the human body requiring treatment, the body having a space formed within the flexible and expandable material; and
a temperature radiating element located within the space formed within the flexible and expandable material of the body, the temperature radiating element being configured to have a soft and malleable shape profile to apply temperature treatment to the predetermined region of the human body;
wherein the temperature radiating element comprises an inner pouch containing a first phase change material that is insertable within an outer pouch comprising a second phase change material, such that, upon insertion, the inner pouch is substantially encapsulated within the second phase change material of the outer pouch and when the body is attached to the predetermined region of the human body requiring treatment, the flexible and expandable material compresses the temperature radiating element against the predetermined region of the human body requiring treatment, so that said temperature treatment apparatus providing both temperature treatment and compression treatment to the predetermined region of the human body requiring treatment.

### Claim 2 (depends on 1)

The temperature treatment apparatus according to claim 1, wherein the inner pouch and the outer pouch of the temperature radiating element are freezable for applying cold therapy to the predetermined region of the human body.

### Claim 3 (depends on 2)

The temperature treatment apparatus according to claim 2, wherein the inner pouch is configured to comprising a plurality of individual pockets containing said first phase change material.

### Claim 4 (depends on 3)

The temperature treatment apparatus according to claim 3, wherein the plurality of individual pockets are movable relative to each adjacent pocket.

### Claim 5 (depends on 3)

The temperature treatment apparatus according to claim 3, wherein when the inner pouch is insertable within the outer pouch comprising a second phase change material, the second phase change material being configured to flow over and between the plurality of individual pockets so as to substantially encapsulate the individual pockets within the second phase change.

### Claim 6 (depends on 1)

The temperature treatment apparatus according to claim 1, wherein the first phase change material has a freezing point that is substantially the same as the second phase change material.

### Claim 7 (depends on 6)

The temperature treatment apparatus according to claim 6, wherein the second phase material is a soft material when frozen and forms a soft layer about the first phase material.

### Claim 8 (depends on 1)

The temperature treatment apparatus according to claim 1, wherein the body comprises one or more arm members configured to extend around said human body, said arm members being secured with respect to said human body for causing the flexible and expandable material of the body to expand, so that the body applies a compression force to the predetermined region of the human body.

### Claim 9 (depends on 1)

The termperature treatment apparatus according to claim 1, wherein the first phase change material has a freezing point that is higher than the freezing point of the second phase change material.
