Abstract
A wound dressing and skin closure system is described which uses a layer of heat reflective metallised foil - 11, joined by a peelable lacquer - 10, to a transparent layer - 9. The outer heat reflective layer can be peeled away from the underlying transparent layer so that the underlying wound can be visualised without disturbance. The outer reflective metallised layer can be printed with any design or logo. The dressing can also be used as an "island dressing" in which a lattice design of wound contact layer 8 enables a proportion of the wound to be visualised through the transparent layer when the outer reflective metallised layer is peeled away. <IMAGE>
Description
A WOUND DRESSING AND SKIN CLOSURE SYSTEM
This invention is a wound dressing and skin closure system which incorporates a reflective metallised film attached to an underlying transparent layer using a peelable lacquer. The reflective metallised layer can be peeled away to reveal the underlying transparent layer.
This double layer, peelable system can be used as a wound or burns dressing and is described as such in international patent
PCT/GB94/00767
Mirotec Medical Ltd., 15C Eurolink Industrial Estate,
Sittingbourne, Kent, has developed a method of joining transparent polyester, or polythene sheets to a reflective metallised film using a peelable lacquer as described in
PCT/GB94/00767. Mirotec Medical Ltd., has also developed the technique of cutting just the reflective metallised film leaving the transparent underlying layer intact.
The material can thus be produced as a series of peelable strips in any desired width.
The underlying surface of the transparent layer can be coated with a suitable, transparent adhesive which would allow the peelable strips to be used as an adhesive wound dressing. The adhesive used could be hypo-allergic.
The application of adhesive strips of reinforced tape to close skin wounds, surgical incisions or skin lacerations is well documented and trade marked products such as "steristrip", "citagraph" or narrow strips of "micropore" or "permicel" have been used for this purpose.
The double layered product described in this invention can be used as an effective wound closure system.
Fig. 1 shows a typical wound (1), the arrows (2) show the positioning of the first "double layer tapes" for wound closure.
Fig. 2 shows the initial double layer tapes in position with further arrows showing the positions of further tapes.
Fig. 3 shows the completed wound closure.
Fig. 4 shows a cross-section of skin (4) with the double layer dressing (3) and the adhesive layer (5). The interrupted arrows show the direction in which the wound is pushed together to assist wound closure.
This peelable skin closure system offers several advantages.
The reflective metallised foil reflects back the body's own infra-red radiation which is helpful in maintaining the wound or burn at body temperature. It is well established that a wound or burn heals most successfully if maintained at body temperature.
The outer layer of the reflective metallised film can be printed with any design, logo, or instructions. Such a dressing can be aesthetically pleasing to the wearer. The outer layer can be printed in 'blue' as required for industrial plasters. A metallised strip can be incorporated in the plaster.
The outer reflective layer can be peeled away from the underlying transparent layer so that the underlying wound can be visualised without disturbance.
This design of adhesive wound dressing using the described double-layer can also be used to produce an "island" dressing.
"Island" dressings are widely used in medicine and surgery and are typified by such commercially trade marked dressings as "Airstrip", "Bandaid", "Mepore", "Primapore" and "Steripad".
The double layered wound dressing described can utilise a wound contact layer which is produced in the form of a lattice. Some examples of which are shown in Fig. 5, Fig. 6, and Fig. 7, although any lattice design could be used.
The lattice can consist of a non-stick wound contact layer (7) backed by an absorbent and protective layer (8), see Fig. 8.
The lattice design of this wound contact layer enables a proportion of the wound to be visualised through the transparent layer without disturbing the wound.
The "peelable" strip of such an adhesive dressing system could cover the total width of the dressing as in Fig. 9 or alternatively the peelable strip could be produced in any proportion of the total width as in Fig. 10.
Fig. 11 shows a cross section of the proposed island dressing where a non-adherent wound contact layer 7 is bonded to an absorbent and protective lattice (8) which in turn is bonded to a transparent layer (9) to which a peelable lacquer is applied (10) which joins the transparent layer to a reflective metallised layer the outer surface of which (12) can be printed with any design or logo required which can be aesthetically pleasing to the wearer.
A typical example of the peelable lacquer mentioned in this invention is "Heat Seal 200101" produced by Swale Coatings and
Inks Limited.
This heat-sealable lacquer is a solvent based heat seal for polyester. The solvent was originally designed for plated metal applications. The heat seal is based on ethyl acetate and is designed to seal to itself only.
This heat seal for polyester offers excellent adhesion to treated and untreated polyester with good seal strengths at low temperatures, (the heat seal threshold being 700C). The dry components comply to F.D.A. 175.300.
This heat seal is normally used in conjunction with a release lacquer when blocked against unprinted polyester.
This heat seal typically has a total solids content of 25.0t, a viscosity of 20 seconds Zahn 3 at 20 C, it is normally applied by a gravure plate at a recommended dry coating weight of 1.0 - 1.5 grams per square metre.
In a specific embodiment of this invention the underlying transparent layer could be the semi-permeable film dressing "Op-Site" (Trademark) produced by'Smith & Nephew Healthcare. In this specific embodiment the Op-Site "breathable" film can be the 'see-through' underlying layer of the double-layer, peelable system described in this invention.
The OF-Site film without any adhesive can be joined by peelable lacquers to the reflective metallised film and produced in the form of mittens or gloves for use in the treatment of - e.g. hand burns, hand injuries and patients with Reynaults Syndrome. As previously described the reflective metallised film can be applied using peelable lacquer so that the underlying skin can be visualised without disturbance. The reflective metallised film reflects back the bodies own infra-red radiation and can strengthen the whole dressing system.
The combined "Op-Site" film and overlying reflective metallised film can be made in any shape for the whole gamut of dressings.
It could also be produced in the form of a sock which could be used as a dressing for foot injuries and in particular for diabetic foot problems. This foot dressing would also help patients with Reynaults Syndrome. The reflective film would enable a strong dressing to be produced suitable for walking on.
The reflective metallised film can be applied in strips which can be "peeled - off" using the peelable lacquer system described in this invention which allows the wound or underlying skin to be visualised without disturbance.
The "Op-Site" film is normally produced by Smith & Newphew
Healthcare with hypoallergenic adhesive which sticks the Op-Site film to the skin. This adherent form of Op-Site can also be used in conjunction with the peelable reflective metallised film.
In an example of this the reflective metallised film is joined to the Op-Site film as shown in Fig. 4 of this invention. The double layer (Op-Site and reflective metallised film 3,) is stuck to the skin, 4, by the hypoallergenic adhesive, 5.
The addition of the reflective metallised film to the Op-Site using peelable lacquer means that the Op-Site film can be used for tape closure of wounds as shown in Figs. 1,2 and 3. The reflective metallised film can be peeled - off if required to visualise the underlying wound without disturbance or if the virtually invisible Op-Site film is wanted to cover the wound in an aesthetically pleasing way.
The attachment of reflective metallised film to the Op-Site film enables the easy handling and placement of the Op-Site strips to produce a very practical tape closure system.
The Op-Site film with attached adhesive and backed by a reflective metallised film can also be used to form a new island dressing. Fig. 10 shows the dressing in the form of a 'plaster' with a peelable strip of reflective metallised film over the adhesive Op-Site.
Fig. 11 shows a cross-section of the proposed island dressing where a non-adherent wound contact layer is bonded to an absorbent and protective lattice, 8, which in turn is bonded to
Op-Site film, 9, to which a peelable lacquer is applied, 10, which joins the Op-Site layer to a reflective metallised layer the outer surface of which, 12, can be printed with any design or logo required.
The double layered wound dressing described in which the Op-Site film, 9, is joined to a reflective metallised film, 11, by a peelable lacquer, 10, can be produced with the reflective metallised film in strip form as shown in Fig. 10. The reflective metallised band can thus be peeled back to view the wound through the lattice wound covering layer as shown in Figs.
5,6,7, and 8. The wound can thus be visualised without disturbance.
The lattice design of the wound contact layer could be made from a variety of dressing materials, e.g. the lattice could be made from a Melolin dressing (Trademark Smith & Nephew Healthcare) or from a hydrophilic polyurethane dressing such as Allevyn (Trademark Smith & Nephew Healthcare) or from a collagen sponge which has haemostatic properties. A calcium alginate dressing could also be used. Such a collagen wound contact layer produced in a lattice form would be particularly helpful for patients with blood clotting problems as the collagen sponge would improve haemostasis and the wound dressing arrangement as shown in Fig. 10 would enable the wound to be viewed without disturbance.
