This first aid bandage is used in the state of hemostasis during the treatment of wound (創傷) in the state of the absorbent pad for the wound surface, and in the promotion phase of the wound is used to transform the absorbent pad for the wound surface into a liquid absorbent pad for the wound portion, In the skin protection step, a liquid absorbent pad is used without a liquid absorbent pad, i.e., a single product is properly modified in the whole treatment phase of the wound so that the liquid absorbent pad which is difficult to determine the timing of removal can be easily removed. In the case of small wounds, the loss of effusion can be prevented, improving the wound healing effect.

Description

First-Aid Sticking Plaster

TECHNICAL FIELD The present invention relates to an emergency band aid for use in hemostasis, drainage, acceleration of treatment, protection, and the like, and a method of using the wound.

A band-aid which can cope at all stages of hemostasis, drainage of a wound, acceleration of treatment, and its protection is proposed (patent document 1). Catheter fixing dressings (patent document 2) and wound bandages (patent document 3) using an annular pad are also proposed. Moreover, the pad division is also proposed (patent document 4, 5).

In Patent Literature 1, the step of promoting the treatment is to remove the liquid absorbent pad, so that the storage of the exudate (the exuding liquid) required for the wound treatment is possible. However, proper maintenance of the exudate is not easy, and (1) it is not easy to judge the timing of removal of the liquid absorbent pad, especially for the general public. (2) In addition, according to the judgment of the present inventors, it was also found that, in the case of a wound with a small amount of the effusion solution, it is difficult to cope with the second step without the liquid absorbent pad. That is, the loss of the exudate required for the treatment of the wound occurs.

Patent Document 1: Patent Registration 4134021 Patent Document 2: Patent Publication Hei 5-285224 Patent Document 3: Practical Publication Hei 01-130716 Patent Document 4: Patent Publication 2008-93396 Patent Document 5: Patent Publication 2008-259629

An object of the present invention is to use the state in the hemostatic stage of the wound treatment process with the absorbent pad for the wound surface, and in the promotion phase of the wound is used to transform the wound absorbent pad to the wound absorbent pad for the wound portion In the skin protection step, the absence of a liquid absorbent pad is used, that is, a single product is appropriately modified and used throughout the entire wound treatment step to provide an emergency band aid with improved wound healing effect.

It is also an object of the present invention to provide a method of using the above mentioned first aid plaster.

In addition to the state with and without the liquid absorptive pad for a wound surface, the state with the liquid absorptive pad for a wound part was newly set. This is a design that does not use on the window surface, and arranges the pad only on the window edge and forms an appropriate space between the window surface and the window contact portion, so as to retain (retain) the effusion solution, and further openness. It is increased. As a result, it is very easy to maintain the proper amount of the effusion solution, and the determination of the timing of changing the pad also becomes easy.

Patent Document 1 has a state in which no liquid absorbent pad is used as a treatment promotion and protection stage, but the most important judgment is a distinction between an initial stage and a treatment promotion stage of a wound treatment and timing of removal of the liquid absorbent pad. If the removal of the liquid absorbent pad is delayed, the exudate is absorbed and removed from the window surface, resulting in a loss of the exudate, and if it is too fast, leakage of the exudate is caused, and thus, adhesion to the skin is caused. In particular, in the case of a wound having a small amount of exudate, the exudate is adsorbed and dispersed between the skin and the coating material even in the absence of the absorbent pad, and the exudate on the wound surface is lost.

However, by using the state of the liquid absorbent pad for the wound portion of the present invention to promote the treatment, the state of the liquid absorbent pad for the wound surface, hemostasis step, and the state without the pad in the protection phase, respectively, the management of the amount of exudate is more appropriate. It is possible to carry out more flexibly, and as a result, the problem can be solved. Specifically, the liquid absorptive pad for wound surface is made into the state which can divide | segment into several small pads.

Thereby, (1) By moving and / or removing each small pad, the liquid absorbent pad for the wound part corresponding to the wound part of the wound is newly renewed on the film-like sheet-like base material and / or the window surface contact part. The formed emergency band-aid is obtained and this can be applied to the wound part. (2) Or, once each small pad is removed, this is directly placed on the skin of the wound portion of the wound portion, and a newly formed liquid absorbent pad for the wound portion such as annular portion is formed on the wound portion, and then the remaining film or sheet is formed. The said wound part can be coat | covered using covering materials, such as a base material of a top and a window surface contact part. In this case, at least a part of the pad may be made non-adhesive by silicon processing or the like in order to prevent the coating material and the liquid absorbent pad for the bismuth from being adhesively fixed. In other words, it is possible to attach the raft, and to deal with distortion caused by the expansion and contraction of the skin. This is also a proposal of a new treatment method for a wound using a coating material after the formation of a liquid absorptive pad for a wound part such as an annular shape on the skin of the wound part.

Immediately after the wound, the hemostatic phase of the wound is used in the state of hemostatic pad for wound surface, and then in the promotion phase of the wound, the liquid absorbent pad for wound is used. By using it in a non-existent state, a more appropriate response to a wound can be made in one product form. That is, (1) use with the absorbent pad for wound surface → use without pad, (2) use with the absorbent pad for wound surface → use with absorbent pad for wound part → It can be used in various combinations depending on the type and the degree of wound, such as use without a pad, (3) use with a liquid absorptive pad for a wound part, and use without a pad.

Proportional relations such as dimensions, shapes, and the like in the drawings differ from the real thing.

It is possible to control the moisture permeability of the window covering by selecting any one of a so-called wet method for keeping the wound surface in a wet environment and a so-called dry method for guiding the wound surface in a dry environment. The water vapor transmission rate is preferably 300 g / m 2 · 24 h or less (according to JIS Z 0208, JIS K 7129) in the case of the wet method, and preferably 300 to 8000 g / m 2 · 24 h (same as above) in the dry method. In addition, the loss of the effusion containing the wound healing ingredient which is indispensable in promoting the treatment can be prevented by the use of a liquid absorbent pad for the wound portion.

The emergency band aid of the present invention covers the "substrate" on the human adhesive film or sheet, the "window contacting portion" provided on at least a part of the substrate, and the window contacting portion, and at the same time, the conscious removal from the surface of the window contacting portion is simple. It consists of a "wet liquid absorbent pad for wound surface" that is fixed and ready for use. The wound absorbent pad for the wound surface is divided into two or more, and by removing and / or repositioning the divided small pad, the film or sheet substrate and / or the window contact portion, or the wound skin A "wet liquid absorbent pad for bismuth" can be newly installed in the shape of annular shape.

In the emergency band-aid of the present invention, the "substrate" is not particularly limited as long as it is flexible and does not impair the feeling of use as a band-aid. Films or sheets formed of existing natural fibers and / or artificial fibers, or films or sheets formed of a polymer material may be appropriately selected and used as a laminate of films or sheets on which at least two or more selected from these substrates are laminated. You may use it.

Examples of the polymer material include synthetic resins such as polyethylene, polypropylene, polyamide, polyester, polyurethane, polyvinyl chloride, polybutadiene, butyl rubber and silicone rubber, natural resins, synthetic rubber, and natural rubber.

In the first aid plaster of the present invention, a pressure-sensitive adhesive layer is formed over at least a part to the entire surface of one side of the "substrate". It does not specifically limit as long as it has adhesive force to the extent that it does not peel by itself during use, and also does not lose adhesiveness easily even if it contacts with moisture by sweating etc. General conventional lipophilic pressure-sensitive adhesive is used, the coating thickness is generally about 10 ~ 70㎛.

In the first aid bandage of the present invention, the "window contact part" means that when the first aid bandage of the present invention is adhered to the wound part, the wound part is covered, and the exudative liquid mainly containing the wound treatment ingredient is kept between the wound surface and the window contact part. It prevents the loss of the effusion solution, and includes moisture permeability, air permeability, and the like which are suitable for each of the dry method and the wet method, and those having some liquid permeability. When the "window contacting part" is a part of the base material, only the layer of the base material is allowed to stay in the effusion containing the wound treatment component to prevent the loss of the effusion solution, and a non-adhesive layer part is provided on a part of the base material. This non-adhesive layer portion can also be used as the window surface contact portion. When the film or sheet laminated and fixed to at least a part of the substrate is used as the window contact portion, the substrate layer, the pressure-sensitive adhesive layer, and the laminate of the film or sheet retain the exudate containing the wound treatment component to prevent loss of the exudate. Can be configured to Specifically, it is preferable to manage the window surface contact portion with moisture permeability. Moreover, it is also possible to make it non-sticking with respect to a wound by silicon processing, etc., or to weak peeling property with respect to an adhesive.

Although it does not specifically limit as a film or a sheet, In addition to the film or sheet | seat formed from the above-mentioned polymeric material, the thing formed from natural fiber, artificial fiber, etc. are mentioned. Also included are hydrocolloid sheets. Examples of the hydrocolloid sheet include hydrophilic polymers such as polyacrylic acid and salts thereof, synthetic rubbers such as polyisobutylene or natural rubber, synthetic resins, natural resins and the like, and hydrophilic polymers.

The "absorbent pad for wound surface" is formed of an absorbent sheet and is not particularly limited as long as it is in contact with blood or drainage and absorbs it, such as paper, nonwoven fabric, woven fabric, and knitted fabric. A non-porous film such as polyethylene or polyester on the window contacting side of the pad, in order to prevent a part of the pad or the adhesive from remaining on the window contacting when the wound absorbent pad for the wound surface is removed from the window contacting portion, A porous film, a net-like thing, etc. can be laminated | stacked and fixed by methods, such as adhesion | attachment or fusion | melting, as a film or sheet | seat for prevention of a residue. Similarly, it is also possible to process by application | coating or spraying using resin, such as polyethylene.

In the present invention, the method of temporarily attaching the liquid absorbent pad for a wound surface to the surface of the window contact portion so as to perform a conscious removal is not particularly limited, but specifically, (1) for the window contact portion and the wound surface The liquid absorbent pad is temporarily fixed to the adhesive with weak adhesive force, or (2) the adhesive force is reduced by dispersing powder such as polyethylene or polypropylene on the surface of the adhesive layer between the window contacting portion and the liquid absorbent pad for wound surface, or ( 3) In the case where the window contact portion is an adhesive layer portion, the surface of the liquid absorbent pad for wound surface is subjected to a release treatment by silicone resin processing or the like, or (4) In the case where the window contact portion is a film or sheet, silicon The method of performing a mold release process by resin processing, etc. are mentioned.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, the present invention is not limited to the following examples.

Example 1

A specific embodiment will be described with reference to the drawings. The numbers in parentheses herein refer to reference numbers in the drawings.

A fleshy cotton nonwoven fabric (55 g / m 2) was used as the base material 1, and an acrylic pressure-sensitive adhesive 2 was applied thereto at a rate of 30 g / m 2. A rayon polyolefin-based nonwoven fabric (90 g / m 2) was used as the wound absorbent pad 4 for wound surfaces, and a polyethylene net (12 g / m 2) was fused and laminated on both surfaces thereof. One side was used as the residual prevention sheet 5, and the other side was used as the non-sticking sheet 6 with respect to the wound surface. Next, an acrylic pressure-sensitive adhesive 2 having a bonding strength of a degree that can be consciously removed easily was applied to the surface of the sheet for preventing residual 5 at a ratio of 20 g / m 2. A polyethylene film (30 g / m 2) was temporarily fixed to the pressure sensitive adhesive layer 2 as the window surface contact portion 3. This was cut into 20 mm x 30 mm, and similarly the non-sticking sheet 6, the liquid-absorbing pad 4 for a wound surface, and the sheet | seat prevention sheet 5 were able to divide into six small pads 9 of 20 mm x 5 mm. And the adhesive layer 2 was cut | disconnected. Moreover, this window surface contact part side was stuck to the adhesive layer 2 of the said flesh-colored cotton nonwoven fabric 1, and was fixed. Subsequently, the release paper 7 was laminated and adhered so as to sandwich them, and then, the laminate such as a liquid absorbent pad for a wound surface was cut to 50 mm x 60 mm so as to be located at the center to obtain an emergency band aid of the present invention. Moreover, when the liquid absorbing pad 8 for bismuth parts is needed, a part of this release paper 7 is peeled off, the said pad part is exposed, for example, two small pads are removed and four wounds are moved. By wrapping a section, a pad having a new shape was installed at a position corresponding to the window section, and an emergency band aid with a liquid absorbent pad for the window section was obtained.
