According to another embodiment of the present invention, the hypertonic solution can be added with general antiseptic or antiBiotic or antiFungal or antiviral solutions which come in close proximity with the surface of the infected skin, by the same method of circulating or soaking provided by the present invention.

Each of the layers, namely the outer or inner layer can be used separately, meaning the inner - non woven fabric soaked with medical hypertonic solution can be put in direct contact of the infected skin, such as Face musk or body roll.

The outer layer can be a container/reservoir for hypertonic or medical solutions that can be also wormed or cooled as needed and be used by its own.

According to some embodiments of the invention, the hypertonic solution is either a concentrated sugar solution, such as honey, or a solution of salts. The external layer may be made of silicone, and the inner layer may be made of non woven material.

The inner layer may be further comprised of two layers - an inner carrier layer for contacting the skin and wound and a middle layer containing a hypertonic solution. It is well in the scope of the invention, wherein the aforesaid hypertonic solution further comprises effective amount of additives.

It is also in the scope of the invention, wherein the aforesaid hypertonic solution is pre-treated or post-treated. Hence for example, it is one embodiment of the invention, the solution is recycled, enriched, reactivated, dried, sterilized, cleans, filtered, dialyzed, applied by a reverse osmosis, extracted, distillated, purified purged or otherwise cleansed or any combination thereof.

It is also in the scope of the invention, wherein the aforesaid hypertonic solution is recycled or treated in a feed backed manner, e.g., as a function to manual-operated feed backing mechanism, as a function of remote-control communicated interface, as a function of physiological and medical parameters of any combination thereof.

It is also in the scope of the invention, wherein the aforesaid hypertonic solution is treated while being recycled. Hence for example, it is another embodiment of the invention; the solution is recycled while, before or after cooling of heating of the solution. Other operations are possible, e.g., applying ultrasonic vibrations, applying a protocol of treatment combining various sessions, e.g., cooling, US vibrations, drying, applying medicaments, etc.

It is also in the scope of the invention, wherein the aforesaid hypertonic solution comprises at least one carrier..

It is also in the scope of the invention, wherein the aforesaid hypertonic solution comprising effective amount of salts, sugars and honey, hydrogels, polymers, their derivatives or the like.

According an embodiment of the invention, sugars (i.e., any monosaccharides, disaccharides or complex carbohydrates) are selected in a non-limiting manner from one or more compositions selected from a group consisting, inter alia, monosaccharides comprising aldoses and ketoses having a number of about 3 to about carbon atoms per molecule, such as triose (e.g., aldotriose such as glyceraldehyde or ketotriose such as dihydroxyacetone); tetraose (e.g., erythrose and threose, or ; pentaose (e.g., arabinose, lyxose, ribose and xylose or ribulose and ; hexaose (e.g., allose, altrose, galactose, glucose (i.e., dextrose), gulose, idose, mannose and talose, or fructose, psicose, sorbose and tagatose) etc. A combination of all said sugars is well in the scope of the invention.

Examples of disaccharides are provided in a non-limiting manner: sucrose, lactose, maltose, trehalose, cellobiose etc. Oligosaccharides are saccharide polymers containing a small number (e.g., three to ten) of component sugars, also known as simple sugars, e.g., Fructo-oligosaccharides etc.

Polysaccharides are selected from homopolysaccharides and heteropolysaccharides, esecpaically those selected from a group consisting, inter alia, of alginates, carrageenan, chitin, ficoll, fructans, galactans, glucans, glycosaminoglycans, mannans, pectins, pentosan sulfuric polyester, plant Gums, bacterial polysaccharides, proteoglycans, sepharose, xylans etc.

According to one embodiment of the invention, the hypertonic solution comprises one or more active substances, such as sugars, salts or honey in a range of about 5% to about 95%; or alternatively in the range of 15% to 80%; or alternatively in the range of 30% to 65% or alternatively about 50% (weight percents).

Reference is now made to FIGS. 1 IA-I IM which illustrate another embodiment of the present invention, in which orthopedic foot support 1100 are provided. The orthopedic foot supports 1100 contains at least one water/air reservoir 1101 filled with water/air or another liquid adapted to better scatter the pressure.

The two reservoirs are coupled via at least one lumen 1102, preferably two (as illustrated in FIG. HC).

Each lumen comprises at least one valve 1103 (see FIG. HD) so as to enable flow from at least one reservoir to the other. A closer view of the valve is given in FIG.

HE.

It should be pointed out that the valve 1103 may enable either unidirectional flow of liquid or two directional flow of liquid.

FIGS. 1 IE - 1 IL provides a closer view of the valves and their mode of operation.

According to one embodiment of the present invention, the valves' mechanism is a mechanical one. According to this embodiment the valve is adapted to infuse liquids into the front sole faster and easier than into the rear sole. In other words the rate of liquid flow to the front sole direction is faster than rate of liquid flow to the rear sole direction. Such mechanism is enables due to the cone shape of the valve. This cone shape is characterized by a first large diameter 1104 and a second relatively small diameter 1105 (see FIG. 1 IF).

Each valve is positioned in lumen 1102 in such a manner that the small diameter 1105 is facing the front sole and the large diameter is facing the rear sole. When the foot is treading or stepping on the rear sole, the valve Opens', 1106 and a relatively large amount of liquid is forced (in a relative high rate) into the front sole

(see FIGS. HG, HH).

Alternatively, when the foot is treading or stepping on the front sole a relatively small amount of liquid is forced (in a relative small rate) into the rear sole (see FIGS. I ll,

HJ).

It should be emphasized that the valves can be electronically operated.

Furthermore, it should be pointed out that the valves can be reversibly operated.

According to this embodiment the valve is adapted to infuse liquids into the rear sole faster and easier than into the front sole. In other words the rate of liquid flow to the rear sole direction is faster than rate of liquid flow to the front sole direction. This can be achieved by (i) simply inversing the direction of the valves; or by (ii) an alternative production of a circulatory foot wrap in which the direction of fluid or air will flow from side to the other by means of the valve direction.

Reference is now made to FIGS. 1 IL-I IM, illustrating the orthopedic foot support

1100 comprising either one valve 1103 (in each lumen 1102) or a plurality of valves

1103.

According to another embodiment, the water/air reservoir 1101 can be located/positioned in different location of the sole for different uses such as Flat feet

(pes planus or fallen arches), can be used for disabled or crippled, or simply for pressure relaxation. According to this embodiment, the valves (1103) can be randomly adjusted (in different directions) so as to create/reduce pressure in desired/undesired locations.

According to one embodiment of the invention, the hypertonic solution comprises or admixed with a predetermined volume of gas, such as air, nitrogen, oxygen or an oxygen-enriched fluid for diffusing oxygen to the body through the skin. Such an embodiment may be provided useful in treating decompression injuries.

According to another embodiment, the device as provided by the present invention can be used for non-medical applications such as facial mask, using the orthopedic foot support for better pressure distribution and for absorbing pressure while walking in athletes as well as non-athletes.
