Description

[Detailed description of the invention] [Field of industrial application] The present invention makes it extremely easy to apply a high-viscosity plaster to skin damage areas such as burns, bedsores, open wounds, etc. The present invention relates to a skin patch that can be applied to damaged skin.

[Prior Art] Conventionally, when applying a plaster to the injured skin area as described above, the plaster is applied and spread on gauze, then affixed to the affected area, and then fixed with a bandage, bandage, etc. as appropriate. was common.

[Problems to be solved by the invention] However, the conventional method of applying the medicine is extremely cumbersome, especially in the case of a highly viscous plaster of 500 cp or more, which requires applying and spreading it on gauze to a certain thickness. The reality was that even this was difficult, and the practical value was significantly diminished.

Furthermore, in general, plasters tend to harden and separate into layers, and are susceptible to the effects of various types of light, making it difficult to prepare them in advance, and the reality is that the above-mentioned treatments have to be applied before use. .

Therefore, the inventor of the present invention has conducted various studies in order to solve the problems of the conventional methods, and has developed the present invention, which allows pre-prepared plasters to be stored extremely stably and which is easy and effective to apply to damaged skin. We devised a pasting body.

[Means for solving the problem] That is, the present invention covers a spreadable high-viscosity plaster of 500 cp or more, which is releasably sandwiched and coated on both sides with non-water-absorbing and water-permeable shape-retaining members, and is packaged in light-shielding and moisture-impermeable packaging. This is a skin injury patch characterized by being covered with a member.

[Examples] The present invention will be further described below with reference to drawings showing examples.

1 is a high viscosity plaster of 500 cp or more, both sides of which are sandwiched and covered with a non-water absorbing and water permeable shape retaining member 2.

The specific method of forming the spread high-viscosity plaster 1 with the shape-retaining member 2 is not limited, but for example, the high-viscosity paste 1 is mechanically applied and spread to a constant thickness on one of the shape-retaining members 2. After that, it is convenient to form a shape-retaining member 2 by covering the outer surface of the high-viscosity plaster 1 with the other shape-retaining member 2.

The high viscosity plaster 1 may be of any type as long as it has a viscosity of 500 cp or more;
For example, a composition paste containing sugar and povidone-iodine (polyvinylpyrrolidone-iodine complex) as active ingredients can be cited as one that can obtain more advantageous implementation effects.

Incidentally, to give an example of the composition paste, sugar 50
Suitable include compositions for repairing damaged skin containing ~90% by weight of povidone-iodine, 0.5-10% by weight of povidone-iodine, 1-20% by weight of water and a buffer to adjust the PH of the composition to 3.5-6.

The thickness of the spreadable clay plaster 1 is appropriately selected depending on the type of plaster and the condition of the affected area, but it is usually preferably about 3 to 6 mm.

The shape-retaining member 2 maintains the spread shape of the high-viscosity plaster 1 and also prevents adhesion between the packaging member 3 and the high-viscosity plaster 1 during wrapping with the packaging member 3, which will be described later. It is used on both sides and is non-water absorbing and water permeable.

Incidentally, when the shape-retaining member 2 has water absorbency, the moisture of the high-viscosity plaster 1 is absorbed, causing its hardening and
In addition to causing dryness, if the shape-retaining member 2 does not have water permeability, exudate from the affected area will not be drained out of the shape-retaining member 2 and will remain there, making it practically impossible to use it as a skin injury patch. Don't do it.

As the shape-retaining member 2, for example, a nylon mesh body, particularly a nylon mesh body having 10 to 300 meshes and a thickness of about 0.01 to 2 mm, can be mentioned.

Reference numeral 3 denotes a packaging member that encloses the spreadable high-viscosity plaster 1 with the shape-retaining member 2 in order to maintain it in a stable state, and is light-shielding and moisture-impermeable. be.

Incidentally, if the packaging member 3 does not have light-shielding properties, the high-viscosity plaster 1 will be affected by various kinds of light rays, easily causing changes and deterioration, and if the packaging member 3 has moisture permeability, However, the moisture in the high viscosity paste 1 easily evaporates, and both lack stable storage stability and cannot achieve the purpose of the present invention.

As the packaging member 3, for example, an aluminum foil bag 31, or an envelope 32 consisting of a non-transparent synthetic resin container 32a having a storage recess and a peelable aluminum sheet 32b that seals the recess is used. These are listed as suitable.

[Operations and Effects] Since the present invention is constructed as described above, the presence of the packaging member 2 makes the high viscosity plaster 1 with the shape-retaining member 2, which is the content, stable when not in use. In addition to being preserved, the presence of the shape-retaining member 2 prevents the high-viscosity plaster 1 and the packaging member 3 from unnecessarily adhering.

In addition, during use, simply take out the contents of the high viscosity plaster 1 with the shape retaining member 2 from the packaging member 3, peel off only one of the shape retaining members 2, and directly apply the exposed high viscosity plaster 1. It is extremely easy to handle because it can be applied immediately by simply pasting it on the affected skin area.

Moreover, since the shape-retaining member 2 of the present invention is non-water-absorbing and water-permeable, it does not absorb water from the high-viscosity plaster 1 itself unnecessarily and exudates from the affected area. can pass through and be discharged to the outside of the shape-retaining member 2, so the outside should be covered with gauze, cotton, etc.
By appropriately covering and fixing a water-absorbing member such as a water-absorbing pad with a bandage or the like, it is possible to prevent the exudate from staying in the affected area.

In addition, the presence of the shape-retaining member 2 prevents the plaster from peeling off during replacement, making it easier to replace.

As explained above, by using the skin injury patch of the present invention, a pre-prepared high viscosity plaster of 500 cp or more can be stably maintained for a long period of time, and it can be applied to the affected area extremely easily without staining the hands of the person administering the medicine. Can be affixed to
This enables extremely simple and effective drug application.
