Definitions

  • T_his invention relates to waterproof skin coverings which protect damaged skin from contact with water for short periods of time.
  • the human skin is the principal means of defense for protecting the human body from infection as well as providing valuable excretory and tempera ⁇ ture regulatory functions.
  • the skin also aids in providing a stable environment for the continued proper functioning of the internal organs.
  • the continued health of the skin contributes significantly to the overall well-being of the body, and therefore it is important that injury to the skin be healed as quickly as possible.
  • the skin has the capability of generating new cells to replace those that have died or become damaged.
  • the body will generate new skin cells in the area of the puncture, cut or burn and thereby cause healing of the wound.
  • healing is promoted in part by the free transfer of gases generated by the affected tissue and by access of the affected tissue to oxygen.
  • a bandage which covers affected tissue may protect the area from direct contact with sources of contamina ⁇ tion, yet still will inhibit oxygen access and ob ⁇ struct gas transfer and therefore have a negative effect on the rate of healing.
  • the excretion of perspiration containing waste body products into the area under the bandage may increase the possibil ⁇ ity of infection to the affected skin area. Also, the affected area cannot be easily monitored where the healing tissue is covered.
  • Evans U.S. Patent 1,707,515 discloses an adhesive strip prepared from a flexible, porous strip of fabric which has marginal portions of one face coated with adhesive material.
  • the adhesive strip is useful as a surgical dressing.
  • the Golub U.S. Patent 4,297,995 discloses a bandage which consists of multiple layers, one of which being capable of dispensing medicine therefrom.
  • a liquid-water impermeable surgical dressing is disclosed in Merriam U.S. Patent 2,949,443.
  • the dressing is made from a resinous film which resists liquid water but is permeable to water vapor.
  • the dressing is applied by activating the surface with solvent prior to application, or by covering the surface with adhesive followed by application.
  • the dressing flexes with the skin and is worn over the wound for long periods of time.
  • bandages known in the art serve to absorb fluid secretions from the affected area.
  • the bandage acts to minimize the risk of particulate contaminants making contact with the affected tissue.
  • Those bandages acting to minimize contamination are generally worn in place for a number of hours or days.
  • the covered skin generally becomes macerated over time, even where the bandage is breath ⁇ able, because fluid generation exceeds the ability of the bandage to wick the fluid away from the affected tissue site.
  • the present invention is directed toward a covering for punctures, incisions, burns, other breaks in the skin, and diseases or growths on the skin undergoing the healing process.
  • the covering protects the affected skin area from contact with water for short periods of time, as when the person takes a shower or bath or otherwise applies water to the skin in proximity to the affected area.
  • the short-term exclusion of both liquid water and water vapor pre ⁇ vents deleterious water contact without otherwise interfering with the healing process. Removal immedi ⁇ ately afterward permits the necessary gas transfer at the affected area and aids in keeping the area dry.
  • the covering is made up of a first sheet which is flexible and initially water permeable, which contains on one side a water-impermeable layer of pressure sensitive adhesive.
  • the adhesive is compat ⁇ ible with the skin to permit contact without adverse side-effects.
  • the pressure sensitive adhesive layer is covered with a barrier sheet to protect the adhe ⁇ sive until use.
  • the mating side of the barrier sheet has a surface which permits removal from the adhesive layer without tearing.
  • the barrier sheet also con ⁇ tains scoring lines preferably parallel and adjacent to the edges of the covering. Prior to applying the covering to the body, the portions of the barrier sheet between the edges and the scoring lines are removed by hand.
  • the centered remaining portion of the barrier sheet is placed over the affected area and is secured in place by pressing the exposed adhesive- coated portion of the first sheet into close contact with the surrounding skin.
  • the skin-contacting side of the barrier sheet is produced from material which is ⁇ terilizable and which in sterilized form would cause no harmful consequences to the injured area during the short period of contact, even in instances where seepage from the affected area may occur.
  • the covering After the person finishes bathing or shower ⁇ ing, the covering is removed from the skin.
  • the covering is inexpensive, and in recognition of the need to minimize infection, the covering is discarded after each use.
  • the waterproof seal around the affected area protects the area from the adverse effects of contact with water, while permitting fast removal to restore the area to the healing exposure of the air.
  • Fig. 1 is a representation -showing the waterproof covering in use.
  • Fig. 2 is a perspective view of the bottom of the covering, showing partial removal of portions of the barrier sheet and exposure of adhesive.
  • Fig. 3 is a perspective view of the top of the covering.
  • Fig. 4 is a cross-sectional view taken on line 4-4 of Fig. 2 showing the individual layers and their relation thereto.
  • the waterproof covering 2 is comprised of an outer flexible sheet 4, an adhesive layer 6, and a barrier sheet 8.
  • a clay coating is applied to one surface of the barrier sheet 8; which is preferably manufactured from paper stock known as white tag liner having a thickness of about 0.08 inch.
  • This coated surface then receives an application of a silicon-based material such as a polysiloxane preferably via roll coating.
  • This surface thus treated, becomes the releasable surface 10 of the barrier sheet 8.
  • the barrier sheet can be produced from supercalendered kraft paper, or polyethylene coated kraft paper.
  • a barrier sheet 8 produced from poly ⁇ ethylene coated paper does not require a further coating of a silicon-based material.
  • the opposite side of the barrier sheet 8 is the skin contacting surface 12.
  • the skin-contacting surface 12 must not degrade in the presence of seepage from the affected skin area or medication applied to the affected area during the short period in which the waterproof covering is in place, typically no longer than ten minutes. Further, the skin contacting surface 12 must be chosen so that it does not stick to the affected skin area or leave pieces in the affected area and thereby inhibit the healing process.
  • the adhe ⁇ sive is applied in a thickness sufficient to render the covering 2 impermeable to liquid water as well as water vapor.
  • the adhesive is pressure sensitive, and is chosen from a group approved by the U.S. Food and Drug Administration for direct contact with skin.
  • the adhesive preferably is a non-sensitizing copolymer of 2-ethylhexyl aerylate and acrylic acid. Such adhesive is produced by the Fasson Industrial Division of Avery International and is designated Avery 1-815.
  • rubber-based adhesives may be used, such as those produced from polyisobutylene or block copolymers of styrene-butadiene-st rene.
  • the adhesive layer may be applied by any number of techniques, such as by rolling, spraying, etc.
  • the top of the covering 2 is formed by the application of a flexible sheet 4 onto the exposed side of adhesive 6.
  • the outer flexible sheet 4 is initially permeable to water, and is sufficiently flexible to permit the waterproof covering 2 to conform to the contours of the body.
  • the material used to produce the flexible sheet 4 may be chosen from a large number of product sources. Broadly, the material used to make the flexible sheet 4 is conform ⁇ able to the body, able to accept adhesive to thereby produce a waterproof layer, capable of being steri ⁇ lized, and unaffected by the action of water and stresses initiated by body movement.
  • a preferred example of a material meeting the listed requirements is a taffeta cloth produced from cellulose acetate fiber, such as the cloth bearing the designation RTS-1-12166, from the Fasson Industrial Division of Avery International.
  • Alternative examples include fabric manufactured from blends of silk and rayon and porous sheets produced from synthetic polymer films.
  • the waterproof covering 2 is preferably sterilized prior to use.
  • the sterilization can be accomplished by a variety of means, such as via chemical, radiation, or heat treatment. Alterna ⁇ tively, where the covering is not sterilized, a sterile cloth or gauze, or other material which will create a space between the skin contacting surface 12 and the affected skin area, may be interposed.
  • the waterproof covering 2 is applied to the body by removal of portions of the barrier sheet as defined by score lines 14.
  • the score lines 14 are adjacent and parallel to the edge 16 of the outer flexible sheet 4.
  • the score lines 14 as depicted in Fig. 2 define a number of edge portions 18 and a single center portion 20.
  • the scoring of the barrier sheet 8 is preferably accom ⁇ plished after laminating of the individual layers to form the covering 2 has been completed.
  • the barrier sheet 8 may be die cut, thus producing a single center portion 20 and a continuous removable edge.
  • the edge portions 18 are removed, exposing part of the adhesive layer 6.
  • the center portion 20 of the barrier sheet 8 is then positioned over the affected skin area such that the skin contacting surface 12 completely covers the affected area.
  • the part of the adhesive layer 6 exposed by removing edge portions 18 is then firmly pressed onto the skin, effecting a waterproof seal around the perimeter of the waterproof covering 2.
  • the waterproof covering 2 is shown in use on the body in Fig. 1; it has particular utility in protecting an affected skin area during showering.
  • the waterproof covering 2 may be offered in a range of sizes. Dimensions of a representative covering sheet are 5 inches by 8.5 inches, with a removable edge portion border of 1 inch. The remain ⁇ ing skin-contacting center portion 20 has a size of 3 inches by 6.5 inches.
  • the outer flexible sheet 4 of the waterproof covering 2 may be supplied in a range of flexibilities to permit waterproofing protection for areas over the entire body, from the relatively flat soft tissue areas in the trunk to highly contoured areas such as the knee and ankle. Further, it is envisioned that the center portion 20 of the barrier sheet skin contacting surface 12 may optionally have absorbent capability to wick seepage that might occur during application of the waterproof covering.
