A hand therapy kit includes a housing having a lid that is expandable from a folded position to an unfolded position to expose a working surface on an inside of the lid. An elastic cord is attached at two or more anchor points on the working surface to define at least one gap for receiving a finger. The finger can be therapeutically exercised by moving from a first position proximal to the working surface to a second position distal to the working surface. The hand therapy kit can also include removable hand therapy modules.

The present disclosure relates to exothermic nose strip devices and compositions, including, methods of making and using them.

A heat pack using supercooled aqueous salt solution that resists premature activation at low temperatures is disclosed. The heat pack comprises two sheets that are bonded together to form a laminated sheet. The heat pack has a first and second compartment. A frangible seal separates the two compartments. One of the compartments contains a supercooled aqueous salt solution. The salt solution contains 15 to 25 percent glycerin by mass.

An exothermic warmer (1) includes an exothermic element (11) that is covered with a first cover sheet (21) and a second cover sheet (22). The first cover sheet (21) is a sheet that is air permeable and does not substantially limit an oxidation reaction. A water-retaining material (12) is provided so as to be at least partially in contact with the exothermic element (11). The exothermic warmer (1) satisfies the following conditions (A) to (C): (A) the difference between the internal temperature of the exothermic element and the highest surface temperature of the exothermic warmer is 10 C. or less; (B) the highest skin temperature obtained when the exothermic warmer is applied to human skin is 38 C. or more and 42 C. or less; and (C) the ratio of the amount (mg/cm.sup.2.Math.10 min) of steam generated in 10 minutes after the start of the oxidation reaction to the mass (g/cm.sup.2) of the exothermic element takes a value of 50 or more and 250 or less.

Provided is a multilayer film for a disposable body warmer outer bag, and a disposable body warmer, which are excellent in gas barrier property that inhibits permeation of oxygen gas, water vapor and the like, which can allow swelling due to hydrogen gas generated during a storage period to be prevented, and which are excellent in seal strength, impact resistance and weather resistance.

A disposable body warmer outer bag formed from a multilayer film comprising a first barrier layer (10) and a second barrier layer (20), wherein the first barrier layer (10) and the second barrier layer (20) consist of a polyvinylidene chloride layer (12) or a polyvinylidene chloride layer (22) obtained by coating at least one surface (upper portion in FIG. 1) of a heat-resistant resin substrate (11) or a heat-resistant resin substrate (21) with polyvinylidene chloride.

Heated socks used to keep a wearer's feet and toes warm. The heated socks include pockets for oxygen-activated chemical heating pouches which generate heat when exposed to air and via friction caused by the wearer when walking, jumping, or other activities and distributed through the sock from toe to ankle to heel. The heated socks are provided with extra cushioning on the bottom of the feet to aid in comfort for the wearer. The heated socks also keep the feet dry from moisture and perspiration.

Embodiments described herein relate to a reusable chemical cold pack. The apparatus includes a body which defines a chamber having two volumes separated by a thin film composite membrane. The thin film composite membrane includes a fabric material sheet, a thermoplastic polymer material sheet, and a polyamide material sheet. A first volume disposed on one side of the thin film composite membrane contains a solvent and a second volume disposed on an opposite side of the thin film composite membrane contains a solute. A check valve is disposed through the thin film composite membrane and enables mixing of the solvent and the solute. The solvent and the solute may also be separated after mixing by diffusion of the solvent through the thin film composite membrane.

The present invention provides a massaging device having two opposite massaging surfaces for massaging human body. A heating unit is encapsulated inside a casing, and the casing includes two parts that are releasably connected to each other, each part having a truncated shape of oblate spheroid. The invention exhibits numerous technical merits such as simpler but robust structure, improved manufacturability, and capability of maintaining warm temperature for longer period of time, among others.
