A thermal therapeutic apparatus is provided which includes a resilient shell, a thermal exchange material, and a flexible sleeve. The resilient shell includes an outer surface and inner cavity in which the thermal exchange material is disposed. The flexible sleeve at least partially covers the shell and defines a vent region which permits communication of air and through the sleeve.

A61F 7/00 - Heating or cooling appliances for medical or therapeutic treatment of the human body
A61F 7/02 - Compresses or poultices for effecting heating or cooling
A61F 7/03 - Compresses or poultices for effecting heating or cooling thermophore, i.e. self-heating
An expandable joint for use in, for example, a headband, includes elastic material, a low-friction sleeve, and a tube. The low-friction sleeve covers at least two opposing sides of a portion of the length of elastic material. The length of elastic material is affixed to the low-friction sleeve at a first end of the low-friction sleeve or a point adjacent to the first end of the low-friction sleeve. The length of elastic material extends beyond a second end of the low-friction sleeve opposite the first end of the low-friction sleeve. The tube substantially encloses the low-friction sleeve. The low-friction sleeve is affixed to the tube at the first end of the low-friction sleeve or a point adjacent to the first end of the low-friction sleeve, and the length of elastic material extends beyond a first end of the tube.

A set of ergonomic handgrips 300 and arm pads 200 make crutches 100 or other walking assist devices more comfortable and reduce repetitive stress injuries. A metacarpal protrusion 402 of each handgrip 300 is angled outward at about 5 to 25 degrees from front 304 to back 306 to place the user's wrists at a more ergonomic angle (approximately 15 degrees inward rotation). The metacarpal protrusion 402 produces a substantially flat surface with a downward slope. Each handgrip 300 spreads the load out over the hand of the user eliminating pressure points. The handgrips 300 can be fitted on crutches 100, a walker, a cane, or another walking assist device. The arm pad 200 has a pair of protrusions 704, 706 that produce a recess 722 on the side facing away from a user's chest which engages a user's arm and keeps the crutch top positioned correctly while the crutch 100 is in use by the user.
A toothbrush holder 100 includes a base 120 and a cover 150. The base 120 has a top 122 and a bottom 102 and includes a cylindrical core 110 and an outer wall 140. The cylindrical core 110 defines a cavity 108 and includes a top end 122 and a bottom end 124. The top end 122 of the cylindrical core is open. The outer wall 140 has a bottom end 102 coincident with the bottom 102 of the base 120 and a top end 142 attached to the cylindrical core 110.
