Other krlown bandages may be medicated or adapted to contain various medicaments, but are not transparent and/or are not self-adherent and/or are not hydrophobic.
An objective of the pre~ent invention is to provide a therapeutic bandage which is, at least in large part, free rom the disadva~tages of known therapeutic bandages and which has the desired properties and characteristics listed above.
Summary o~ the Invention Broadly the present invention relates to an elastomeric therapeutic ambulatory material for bandages or the like comprising a ~ubs~rate made of elastomeric material, the inner and outer suraces of said sub trate being covexed by a thin film of a transparent, porous, hydrophobic material, the inner surface of said substrate being self-adh~sive when applied directly to the skin of a user, said bandage material including an antibacterial substance incorporated into said elastomeric material.
The substrate is made of a mesh of elastic fibers 8uch as polyurethane~ or polyamide fibers. The antibacterial agent is incorporated into said substrate and said inner surface. In another embodiment of the present invention the antibacterial agent is incorporated into the inner surface of the substrate. The thin film co~prises a film of a coating such as methicone or silicone film. In still another embodiment of the present invention the elastomeric therapeutic ambulatory material forms a stocking or suits for burns. Into the inner surface of the substrate is incorporated an anti-pruritic substance.
The material has low allergic potential.
Brief Descripti_n of_ the Drawin~s Fig. 1 i~ a plan of a portion o~ a she~t frQm which the bandages of the present invention can be cut, ancl Fig. 2 is a cro~s~sectlon view of the bandage shown in Fig. 1, taken along line 2-2 of Fig. 1.
Referring now to the drawings, Figs. 1 and 2 show a substrate 10 made of elastomeric of elastomeric material comprising a mesh of elastic fibers such as polyuretanes or polyamide fibers. The outer (12) and inner ~14~
surfaces of the suhstrate 10 are covered with a thln film consisting of transparent, porous, hydrophobic material such a~ a methicone or a silicone coating. The inner surface 14 is covered by self-adhesive layer 16 to be ~, :
applied directly to the ~kin of the user. Xt also has a low allergic potential.
In one embodiment of the pr~sent invention a~
antibacterial agent 18 is incorporate~ within the substrate 10 and inner surface 14.
In another embodimen~ of the present invention the antibacterial agent 18 is incorporated only into inner surface 14 according to the specific needs. A preferred antibacterial agent for purposes of the present invention 0 i5 mupirocin, but other antibacterial agents may be incorporated, according to specific needs.
In still another embodiment of the present invention the inner surface 14 can be treated wi~h an anti-pruritic ~ub~tance (20) such as mixture of lignocaine and prilocaine (EMLA). This substance is applied on the base of the inner ~urface 14 which is in contact with the skin to control the pruritus and to some extent pain. The adhesive used for the adhesive layer 16 can be any suitable adhesive, and may, for example, be similar to adhesi~es used by the 3M Company.
The material of the present invention is suitable for manufacturing of either elastomeric, transparent, antibacterial, self-adhesive therapeutic bandage~, or stockings or suits for burn vic~ims.
The material used for manufacturing the thin film is a methicone synthetic or other ~ilicone coatirlg. This ambulatory therapeutic bandage is preferably o~ 3"-6"
width and 1-3 meters in length, for placement on extreMities of the body, ~rom toes to either below the knee or below the inguinal area in a circular manner exerting compressing pressure on the wearer' leg. The method of application of the therapeutic ambulatory stocXings on the wearer's leg includes circumfersntial wrapping, overlapping the æide edges of the therapeutic ambulatory stockings. The therapeutic ambula~ory qtockings contains ~elf-adhe~iv~ layer 15 which is not self-adheren~ and which might be removed from the ~kin without damaging the skin.
The bandage of the present invention can be of various thicknesses. The therapeutic ambulatory bandage of the present invention is useful for txeating phlebitis, sta~is dermatitis, ischemic ulcer and for administration of sclerotherapy. Said therapeutic ambulatory bandage can be applied under these conditions either temporarily or for a longer period of time without the need to remove it for inspection or bathing and without the need to remove it for administration of sclerotherapy which can be done through the bandage. The therapeutic bandage will ensure the ability o the observer to follow the healing process without the need to remove the bandage and will allow the physician to administer sclerotherapy without the need to remove the bandage which can be left in place for an indefinite period of time. The ~mbulatory therapeutic bandage is made of transparent elastic se~i per~eable hydrophobic material which will ensure the application of uniform supportive pressure of a pre-determined magnitude on the leg's venous syste~ and can be applied to the whole leg from the metatarsal to the inguinal area, providing long-standing support to the superficial venous system and so can be used for treatment of superficial varico6ities and deep venous 6y~tem insuf~iciencies. The ambula~ory treatment oE said diseaseR will be then done by mechanically compres~ing the leg's so~t ti8sue, e~tablishing a continuous pres3ure gradient ~rom the external skin inwardly forcing the blood from the superficial venous system to the deep venous system. The method of application of the therapeutic ambulatory stocking on the user,s leg includes circumferential wrapping, overlapping the side edge~O
The bandage of the present inv~ntion has great advantages in trauma nd burn in]uries as well as in plastic surgery. The quality of the bandage assures that it is more than simply a mechanical barrier compressing the tissue.
This invention relates to therapeu~ic bandages and more particularly to elastomeric therapeutic ambulatory bandage~.

Summary o~ the Invention Broadly the present invention relates to an elastomeric therapeutic ambulatory material for bandages or the like comprising a ~ubs~rate made of elastomeric material, the inner and outer suraces of said sub trate being covexed by a thin film of a transparent, porous, hydrophobic material, the inner surface of said substrate being self-adh~sive when applied directly to the skin of a user, said bandage material including an antibacterial substance incorporated into said elastomeric material.
The substrate is made of a mesh of elastic fibers 8uch as polyurethane~ or polyamide fibers. The antibacterial agent is incorporated into said substrate and said inner surface. In another embodiment of the present invention the antibacterial agent is incorporated into the inner surface of the substrate. The thin film co~prises a film of a coating such as methicone or silicone film. In still another embodiment of the present invention the elastomeric therapeutic ambulatory material forms a stocking or suits for burns. Into the inner surface of the substrate is incorporated an anti-pruritic substance.
The material has low allergic potential.
Brief Descripti_n of_ the Drawin~s Fig. 1 i~ a plan of a portion o~ a she~t frQm which the bandages of the present invention can be cut, ancl Fig. 2 is a cro~s~sectlon view of the bandage shown in Fig. 1, taken along line 2-2 of Fig. 1.
Referring now to the drawings, Figs. 1 and 2 show a substrate 10 made of elastomeric of elastomeric material comprising a mesh of elastic fibers such as polyuretanes or polyamide fibers. The outer (12) and inner ~14~
surfaces of the suhstrate 10 are covered with a thln film consisting of transparent, porous, hydrophobic material such a~ a methicone or a silicone coating. The inner surface 14 is covered by self-adhesive layer 16 to be ~, :
applied directly to the ~kin of the user. Xt also has a low allergic potential.
In one embodiment of the pr~sent invention a~
antibacterial agent 18 is incorporate~ within the substrate 10 and inner surface 14.
In another embodimen~ of the present invention the antibacterial agent 18 is incorporated only into inner surface 14 according to the specific needs. A preferred antibacterial agent for purposes of the present invention 0 i5 mupirocin, but other antibacterial agents may be incorporated, according to specific needs.
In still another embodiment of the present invention the inner surface 14 can be treated wi~h an anti-pruritic ~ub~tance (20) such as mixture of lignocaine and prilocaine (EMLA). This substance is applied on the base of the inner ~urface 14 which is in contact with the skin to control the pruritus and to some extent pain. The adhesive used for the adhesive layer 16 can be any suitable adhesive, and may, for example, be similar to adhesi~es used by the 3M Company.
The material of the present invention is suitable for manufacturing of either elastomeric, transparent, antibacterial, self-adhesive therapeutic bandage~, or stockings or suits for burn vic~ims.
The material used for manufacturing the thin film is a methicone synthetic or other ~ilicone coatirlg. This ambulatory therapeutic bandage is preferably o~ 3"-6"
width and 1-3 meters in length, for placement on extreMities of the body, ~rom toes to either below the knee or below the inguinal area in a circular manner exerting compressing pressure on the wearer' leg. The method of application of the therapeutic ambulatory stocXings on the wearer's leg includes circumfersntial wrapping, overlapping the æide edges of the therapeutic ambulatory stockings. The therapeutic ambula~ory qtockings contains ~elf-adhe~iv~ layer 15 which is not self-adheren~ and which might be removed from the ~kin without damaging the skin.
The bandage of the present invention can be of various thicknesses. The therapeutic ambulatory bandage of the present invention is useful for txeating phlebitis, sta~is dermatitis, ischemic ulcer and for administration of sclerotherapy. Said therapeutic ambulatory bandage can be applied under these conditions either temporarily or for a longer period of time without the need to remove it for inspection or bathing and without the need to remove it for administration of sclerotherapy which can be done through the bandage. The therapeutic bandage will ensure the ability o the observer to follow the healing process without the need to remove the bandage and will allow the physician to administer sclerotherapy without the need to remove the bandage which can be left in place for an indefinite period of time. The ~mbulatory therapeutic bandage is made of transparent elastic se~i per~eable hydrophobic material which will ensure the application of uniform supportive pressure of a pre-determined magnitude on the leg's venous syste~ and can be applied to the whole leg from the metatarsal to the inguinal area, providing long-standing support to the superficial venous system and so can be used for treatment of superficial varico6ities and deep venous 6y~tem insuf~iciencies. The ambula~ory treatment oE said diseaseR will be then done by mechanically compres~ing the leg's so~t ti8sue, e~tablishing a continuous pres3ure gradient ~rom the external skin inwardly forcing the blood from the superficial venous system to the deep venous system. The method of application of the therapeutic ambulatory stocking on the user,s leg includes circumferential wrapping, overlapping the side edge~O
The bandage of the present inv~ntion has great advantages in trauma nd burn in]uries as well as in plastic surgery. The quality of the bandage assures that it is more than simply a mechanical barrier compressing the tissue.
