Description

  The present invention relates to a wound protection film forming kit for forming a wound protection film having a structure different from that of an emergency bandage or gauze and performing a function of covering and protecting the outside of a wound. The wound protective film formation kit of the present invention can form a transparent protective film that is impermeable to moisture, gas, etc., for example. It has excellent characteristics that can be observed.

Conventionally, for wounds such as cuts, injuries, and abrasions on the skin, apply a medicine to the wound and directly apply a first-aid adhesive plaster on the wound, or apply a gauze to the wound that has been applied with the medicine. Care has been taken by wrapping a bandage over it or applying a bandage.
In order to treat wounds such as cuts, incisions in surgery, ulcers, burns, etc., one of the purposes of applying bandages to the wound is to reduce the risk of wound infection. The dressings need to be changed at regular intervals to ensure that the wound and surrounding area are as clean as possible and depending on the state of healing. Sensitive bandages prevent external contamination by sealing the wound, moistening the tissue and promoting healing. Many types of bandages for protecting and treating wounds have been used, and many have been proposed.

  Some specific examples are given below. For the purpose of adding functionality and simplifying the use of bandages, the bioactive agent is maintained by making the covering material covering the wound part biodegradable. A biodegradable coating material that can be released and formed from a biodegradable / bioerodible thermoplastic polymer that is insoluble in water or body fluid and an organic solvent that is miscible or diffuses in water or body fluid A biodegradable film coating comprising a composition, a container enclosing the liquid composition, and a release means liquefied with the liquid composition capable of administering the liquid composition onto human or animal tissue The absorption of the material (Patent Document 1) and wound exudate can be observed, the wound exudate is removed, the damage to newly formed tissue is minimized, and the possibility of bacterial contamination of the wound is minimized, In addition, when replacing the bandage is optimal As a dressing that effectively determines the padding, a pad that contacts the wound without adhering is adhered to a substrate that is impermeable to bacteria and fluids, through which the pad absorbs wound exudate. Observed bandages (Patent Document 2) and the like have been proposed.

In addition, regarding a technique for forming a film for dressing by applying a composition containing a polymer compound to a wound, a composition comprising a dialkylaminoalkyl methacrylate / methacrylate polymer and a plasticizer can be sprayed. A film-forming bandage formed by coating on a wound and drying naturally (Patent Document 3), a fast-drying film-forming group containing monovalent lower alcohol-compatible polyvinyl alcohol, monovalent lower alcohol, and ester gum An agent (Patent Document 4) is known.
As another example, a string with several adhesive seals on one side is bent, the strings are bent with the adhesive seal facing outward, and the outer periphery of the wound is surrounded by a fort. A wound protector (Patent Document 5) that can protect a wound from contact with the protective net by providing a protective net is proposed.

  In the case of general treatment for most surgical traumas (including burns), a semi-permanent cover or dressing is required for some time of treatment. The purpose of this dressing includes mechanical protection of the wound, prevention of microbial contamination, prevention of wound dehydration, removal of wound exudate, and high local level release of therapeutic agents. Since wound treatment varies depending on the type of wound and the severity of the disease, some natural or synthetic dressings have been adapted for short and long term application. However, most of these coating materials have improvement points such as unsatisfactory handling and cost. For example, an opaque bandage often cannot reliably cover a wound because it is difficult to confirm the wound. In addition, it is difficult to provide dressings that satisfy the requirements such as difficult adhesion to the skin, difficulty in confirming the healing state of the wound, and ease of peeling without damaging the wound. It was.

  In addition, if you apply an emergency bandage with a batter directly on the wound, or apply gauze, etc., or apply a bandage on it, or apply a bandage, etc. Water easily soaks, so for example, when doing water work such as bathing, cooking, washing, etc., waterproof treatment such as glove from the outside or covering with waterproof sheet, wrapping etc. so as not to wet the wound It was taken specially. However, such waterproofing treatment is cumbersome, and if the treatment is poor, the waterproofing function may be incomplete and water may enter, and not only the wound and its vicinity but also the surroundings are wider than necessary. There was a need to waterproof treatment. Therefore, the present inventor has developed a sealant for forming a wound protective film as a new application of striple coating (Patent Document 6). However, bandages, gauze, etc. were opaque, and it was impossible to observe the healing state of the wound.

The present invention solves the problems of the conventional products, and covers the wound with a flexible vinyl film, and the end of the joint is mixed with the skin to provide waterproofing and dustproofing. An object of the present invention is to provide a kit for forming a wound protective film, and to form a transparent wound protective film in which the healing state of the wound can be directly viewed through the transparent protective film.
That is, the present invention, for example, covers the wound with a transparent sheet such as a transparent and flexible vinyl film, and provides a connection portion around the entire periphery of the transparent sheet so that the end portion and the skin are integrated with each other. The present invention relates to a wound protection film formation kit that is sealed and airtight, and allows a treatment state of the wound to be directly viewed through a transparent sheet.

  In addition, the present invention makes use of the properties of an adhesive resin composition such as a strippable coating agent in forming a wound protective film, as a sealing material between the transparent sheet and the skin, or as a bonding material thereof, and further as a transparent sheet. By using it as a transparent film that reinforces it while maintaining transparency, a protective film can be formed easily and accurately.

The present invention comprises the following technical matters.

Moreover, the material constituting the wound protective film is harmless to the human body, is relatively flexible, has good compatibility with the skin, does not feel uncomfortable, and can be easily peeled off by hand after use. . Therefore, the transparent wound protective film formed by the present invention is optimal as a wound protective film having a waterproof and dustproof function, and it is easy to use, and since the wound is wet during bathing or water work, It can be surely protected. In addition, it is possible to impart appropriate handling characteristics to the stopperable coating by mixing limonene.

  The wound protection film of the present invention can contain disinfectants and therapeutic agents for wounds, and even if you do not have disinfectants or therapeutic agents, you can perform emergency care and hemostasis accurately, so it is due to bacterial infection Purulosis can be effectively prevented. Also, as an adhesive material for forming the connection part, an adhesive containing a tube or a stoppable coating agent is filled into the inside of the high-pressure gas and the aerosol tube, and the sealant is directed toward the wound from an open / close nozzle that can be operated manually. It is convenient to form the connecting portion if it can be sprayed. In addition to the formation of the connection portion, particularly when a stoppable coating agent is sprayed with an aerosol tube, it is possible to form a transparent film that reinforces the entire transparent sheet while maintaining its transparency and flexibility. .

For example, the wound protective film formed by the present invention is composed of a transparent sheet and a connecting portion that integrates the transparent sheet and the skin around the transparent sheet, and the connecting portion can be integrated by bonding the transparent sheet to the skin surface. If it is, it will not specifically limit, However, It is preferable to provide in the surrounding surface of a transparent sheet so that it may be formed from an adhesive material and the sealing performance of a wound can be maintained.

  The connecting portion integrates the transparent sheet with the skin, and is made of, for example, an adhesive material such as an adhesive provided around the back surface of the transparent sheet. These materials have sufficient adhesive strength to integrally bond the transparent sheet to the skin, do not peel easily from the skin near the wound, and peel off for a period sufficient to protect the wound. At the same time, it must be easy to peel off from the skin when it is no longer necessary to protect the wound. As an example of such an adhesive material, use of the well-known composition currently used as the adhesive material currently used for the conventional adhesive bandage, the adhesive agent etc., or a strippable coating agent is mentioned, for example. The adhesive material may be applied directly to the transparent sheet and the skin.

A specific example of the wound protective film formed by the present invention will be described based on the following schematic diagram.
In FIG. 1, the adhesive material 5 covers the surface of the transparent sheet 2 and the skin 3 and integrates them. The adhesive material 5 used for connecting the transparent sheet 2 to the skin surface 3 is provided on the skin surface 3 extending outward from the end of the transparent sheet 2. The adhesive material 5 is made of a material that has a sufficient adhesive force to the transparent sheet 2 and the skin 3, and is selected from materials that do not cause allergies or other effects on the human body. When the wound protection shown in FIG. 1 is viewed from above, as shown in FIG. 2, the adhesive material 5 covers the skin surface 3 from the end of the transparent sheet 2 and integrates them, and a transparent window is formed in the central portion 21. Has been. When a highly transparent material is used as the adhesive material 5, the adhesive material 5 may be provided on the entire surface of the transparent sheet 2 as shown in FIG.

The transparent sheet 2 is integrated with the skin 3. The porous structure 61 is generally formed by processing the end of the transparent sheet 2 or by integrating a cloth or the like that is another porous material with the transparent sheet 2. As the adhesive, an adhesive applicable to the human body, a stoppable coating agent, or the like is used.
FIG. 5 shows an example in which a member 62 made of a material having flexibility and liquid permeability is provided at the end of the transparent sheet 2. The member 62 contributes to integration by adhesion between the transparent sheet 2 and the skin, and also serves as a cushioning material between the transparent sheet 2 and the skin 3. The size of the member 62 is not particularly limited, and the member 62 may be provided on the inner side of the end portion of the transparent sheet or may be provided so as to protrude to the outside.
FIG. 6 shows an example in which the adhesive material 5 is formed by spraying or the like. For example, the strippable coating agent 51 is continuously provided on the surfaces of the transparent sheet 2 and the skin 3 to form a connection portion, and the transparent sheet 2 is integrated with the skin 3. When the adhesive material 5 is provided by spraying, coating, or the like, the outer periphery of the transparent wound protective film may have an irregular structure as shown in FIG. Since the strippable coating agent 51 forms a transparent film, the strippable coating agent 51 may be sprayed and applied to the entire surface of the transparent sheet 2 to form a connection portion. It becomes like this.

  FIG. 7 shows an example in which the adhesive 52 for forming a wound protective film accommodated in the tube with lid 11 is pushed out. Apply an agent 4 such as a disinfectant or a therapeutic agent to the wound 1, cover with a transparent sheet 2, open the lid of the tube 8, and press the body of the tube 8, so that the adhesive 52 is transparent from the tip of the tube 8. An appropriate amount is pushed out toward the end of the sheet 2. Thereafter, the adhesive 52 is pushed and spread with a fingertip or a spatula to form a continuous coating on the transparent sheet 2 and the skin 3. If it carries out like this, the adhesive agent 52 will be continuously apply | coated thinly on the outer peripheral part of the transparent sheet 2, and the surface of the skin 3, and a connection part will be formed. This is dried and solidified as it is, and the transparent sheet 2 is integrally bonded to the skin surface 3.

Next, the formation of a wound protective film using a strippable coating agent will be described in detail.
The strippable coating agent is, for example, a sol-like paste in which a polyvinyl chloride (PVC) paste resin is dispersed in a plasticizer, and is a resin composition conventionally called a paste resin because it is used for paste processing. . The strippable coating agent can be used as a coupling part in forming the transparent wound protective film of the present invention by utilizing the following characteristics.
(1) It must be completely waterproof.
(2) Harmless to human body.
(3) It must be peelable, easy to peel off after application, and should not damage the object being applied.
(4) Be relatively flexible.
(5) Appropriate adhesion between plastic and skin surface.

  The strippable coating agent for forming the transparent wound protective film of the present invention contains, for example, liquid vinyl plastisol as a main component. The strippable coating agent (vinyl plastisol) is mixed with a solvent for reducing the inherent viscosity to an appropriate viscosity. As the solvent, those which are harmless to the human body are selected, and furthermore, the drying function inherent to the strippable coating agent (that is, the function of drying and curing in a relatively short time after application) and the peeling function after drying (that is, the function) The physical properties are selected so as not to impair the function that can be easily peeled off by hand after drying.

  For example, limonene can be selected as the solvent having such characteristics. This limonene is a natural hydrocarbon component extracted from the peels of citrus fruits such as mandarin oranges, is colorless and transparent, harmless to humans, and lowers its inherent viscosity and stickiness when dissolved in a strippable coating agent. To do. Therefore, it is possible to set a viscosity suitable for forming the transparent wound protective film of the present invention by selecting the blending amount of such a solvent.

  In order to form a connection part using a strippable coating agent as an adhesive material, this coating agent is filled in an aerosol tube together with a high-pressure gas and sprayed around the transparent sheet 2 covering the wound 1, so that the transparent sheet 2 and the skin 3 are formed. It is good to integrate. First, a medicine 4 such as a disinfectant or a therapeutic agent is applied to the wound 1, and then the top of the nozzle is pushed as shown in FIG. 6, and the coating agent is sprayed therefrom toward the periphery of the end of the transparent sheet. Thereby, as shown in FIG. 2 or FIG. 3, the sealant is continuously applied thinly on the outer peripheral portion of the transparent sheet 2 and the surface of the skin 3. 3 integrated into the surface. Thus, the transparent wound protection of the present invention is obtained. When an aerosolized strippable coating agent or an adhesive is used, the transparent waste opening protective film of the present invention can be formed simply by spraying from the nozzle toward the wound 1.

  The strippable coating agent as the adhesive material applied on the upper side of the wound in this way simply forms a transparent wound protective film that completely blocks and covers the wound 1 from water and dust by simply solidifying it. be able to. In addition, the connections formed in this way are selected from materials that are harmless to the human body, are relatively flexible, have good fit with the skin, and do not feel uncomfortable, and after use, the transparent wound protective film can be easily peeled off by hand. it can. As the strippable coating agent or adhesive, the most suitable one is selected to form a transparent wound protective film that is transparent, airtight, waterproof and dustproof. By doing so, the usability is improved and the wound can be reliably protected from getting wet during bathing or water work.

  The above wound protective film will peel off naturally from the skin over time, but if you want to remove it early, you can easily remove it by hand, for example by attaching a fingernail or appropriate tool to the protective film. Can be peeled off. Further, since the peeled transparent wound protective film is harmless, it can be disposed of anywhere and there is no need to pay attention to the disposal place. In addition, if the transparent sheet contains chemicals such as disinfectants and therapeutic agents for wounds, emergency care and hemostasis can be performed accurately even if no disinfectants or therapeutic agents are present, and bacterial infection Can effectively prevent suppuration.

The drying time of the connection part using the above strippable coating agent, the hardness and thickness of the film, etc. are the composition of the strippable coating agent (for example, vinyl plastisol) and the blending ratio of this with a solvent (for example, limonene). It can be adjusted appropriately by changing.
Although specific examples of the present invention have been described in detail above, the present invention can be modified in various ways without departing from the gist thereof.

  In addition to the vinyl plastisol, the strippable coating agent as a material for forming the connecting portion may of course use a strippable coating made of other materials such as ethyl cellulose and synthetic rubber latex. The transparent sheet, strippable coating agent (vinyl plastisol), and adhesive material of the present invention are appropriately mixed with pigments, dyes, lame, etc. that are harmless to the human body, so that sealants of various colors and patterns can be obtained. Also good.

  According to the present invention, it is possible to adapt to the surface of a living body, which is not obtained by conventional coating, has excellent adhesion, and has many round parts and uneven parts, and the wound healing state can be visually observed. Thus, wound healing can be achieved in a short period of time because it is possible to easily determine the timing of removal of the covering, replacement, and selection of a treatment method. In addition, since the wound is confirmed from the transparent window, it is possible to accurately and easily cover the wound with the coating material, the effect and efficiency of the coating are improved, and the wound is not damaged without impairing the function of the biological surface. Protected. The present invention having such characteristics is excellent in that it can be applied in a wide range of fields such as medical care, beauty, and animal husbandry, and can greatly contribute economically and socially.
