## Abstract

The present invention discloses an improved hand therapy apparatus, wherein the hand is supported in an elevated upright position, and a therapeutic fluid and a therapeutic energy are directed at the hand.

## Claims

### Claim 1

A hand therapy apparatus comprising:
a tank having a removable top, a bottom and a port substantially near the bottom thereof for the insertion of said hand along with its forearm into said tank, said tank further having sleeve means for sealing said forearm in said port;
an adjustable support having a member encircling said hand for supporting said hand, substantially in an elevated totally upright position near the center of said tank;
means for directing a therapeutic fluid at said hand;
means for controlling the temperature of said fluid; and
means for directing a therapeutic energy at said hand.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein said member completely encircles said hand and is substantially in the shape of a ring,

### Claim 3 (depends on 2)

The apparatus of claim 2 wherein said therapeutic fluid is water.

### Claim 4 (depends on 3)

The apparatus of claim 3 wherein said means for directing said water comprises hydro jets positioned circumferentially about said ring.

### Claim 5 (depends on 2)

The apparatus of claim 2 wherein said therapeutic energy is acoustic energy.

### Claim 6 (depends on 5)

The apparatus of claim 5 wherein said means for directing said acoustic energy comprises sonic jets positioned circumferentially about said ring.

### Claim 7 (depends on 2)

The apparatus of claim 2 further comprising:
a holding tank for storing said fluid;
a pump means for recirculating said fluid from said directing means to said holding tank; and
a filtration means between aid directing means and said holding tank.

### Claim 8

A method of treating an injured hand comprising:
inserting said hand with its forearm through a sleeve means into a tank having a removable top and a bottom, with said hand inserted through a port substantially near the bottom thereof;
sealing said forearm in said port;
supporting said hand in an elevated upright position by encircling said hand with a member mounted on an adjustable support positioned substantially near the center of the tank;
directing a therapeutic fluid at said hand; and
directing a therapeutic energy at said hand.

### Claim 9 (depends on 8)

The method of claim 8 further comprising the step of:
exercising said hand.
