## Abstract

An inflatable pillow is disclosed, as for elevating the hand during a period of healing. A pair of inflatable base chamber sections define an L-shape to engage the human upper limb with elbow flexed at an angle of some 90.degree.. A pair of inflatable lateral chamber sections somewhat triangular in profile are affixed at the sides of the L-shaped member for retaining the configuration and providing dimensional cushioning. The interior chambers of the inflatable sections are interconnected, and a flex valve is provided for inflating and deflating the pillow. A pair of strap members bridge the lateral sections to close the pillow about the upper limb. As disclosed, the structure comprises transparent sheet, vinyl-like material.

## Claims

### Claim 1

An air pillow for the human upper limb, comprising:
inflatable base chamber sections extending in an angular relationship to provide cushion surfaces for the arm and forearm when flexed;
a pair of inflatable lateral chamber sections formed of transparent, flexible sheet material and affixed at the sides of said base chamber sections bridging the angle therebetween and defining therewith an angular space to receive said upper limb and positioned to support the distal portion of said upper limb therebetween and in an upright position;
means for inflating and deflating said chamber sections; and
closure means including at least one strap closure affixed between said pair of lateral chamber sections.

### Claim 2 (depends on 1)

A pillow according to claim 1 wherein said chamber sections are internally interconnected and wherein said means for inflating and deflating comprises a flex valve mounted in one of said chamber sections.

### Claim 3 (depends on 1)

A pillow according to claim 1 wherein said base chamber sections comprise opposed, edge-sealed sheets of flexible material substantially rectangular in configuration and said lateral chamber sections comprise spaced-apart opposed sheets of flexible material of substantially triangular configuration.
