Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a deodorant bandage, and more specifically, it is a bandage that adsorbs and removes the unpleasant odor of pus when it is wrapped around an affected area where pus has developed.

[0002]

[Prior Art]

 In order to remove the unpleasant odor generated from the affected area where the pus leaks and leaks, a sheet made of a very thick urethane sheet impregnated with activated carbon has been used. However, the urethane sheet cannot be made thin like a bandage because of its material, and it is inconvenient to handle. Moreover, unlike bandages, it cannot be used on almost all parts of the body. Moreover, it was rarely used unless it was particularly necessary, such as when the odor was extremely intense or when an unbearable odor was generated.

Conventionally, there is no known bandage in which activated carbon is attached to a sheet of gauze or a thin non-woven fabric of the same degree as that of gauze, or an organic acid or the like is further attached.

When the affected area becomes purulent and a foul odor is generated, an air purifier is often used to clean the entire room air. However, it is undeniable that such a deodorizing method leaves considerable discomfort.

According to the present invention, activated carbon powder and an organic acid such as malic acid or L-ascorbic acid are attached to a bandage of gauze or a thin non-woven fabric of the same level as that of a gauze so that it can be easily used like a normal bandage. Therefore, it is intended to provide a bandage capable of adsorbing and removing the unpleasant odor of pus when wrapped around a suppurated affected area.

[0006]

[Means for Solving the Problems]

 The present inventor examined a method of impregnating activated carbon powder to a gauze used for a bandage or a sheet of non-woven fabric having a thickness similar to that of gauze to remove an unpleasant odor of pus generated from a suppurated affected area. As a result, it was found that when activated carbon powder is dispersed in an emulsion as a medium and impregnated with gauze or the like and impregnated with activated carbon, the same flexibility as that of a normal bandage can be maintained. Furthermore, in order to remove the amines, which are the main cause of the unpleasant odor of pus, we examined a method of attaching organic acids such as malic acid and L-ascorbic acid to the other side of the bandage that contacts the skin. Based on this, the present invention has been reached.

That is, a gauze or thin non-woven fabric is impregnated with an emulsion in which activated carbon powder is dispersed, and malic acid, L-ascorbic acid or citric acid is attached to one side of the gauze or a thin non-woven fabric to form a roll-shaped or sheet-shaped deodorant bandage. is there.

The present invention will be described in detail below.

It is necessary to use gauze or a thin non-woven fabric as the base material of the bandage of the present invention. Gauze is the best for maintaining high air permeability, and non-woven fabric is suitable for impregnating a large amount of activated carbon powder.

In order to impregnate the activated carbon powder on the base material of the bandage of the present invention, it is necessary to use an emulsion in which the activated carbon powder is dispersed. The activated carbon powder used at this time is preferably a fine powder having a particle size as small as possible, and particles of 200 to 300 mesh are preferred. This is because the malodor is absorbed at a high rate and the flexibility of the sheet is not impaired when the sheet of gauze or the nonwoven fabric is impregnated.

As the emulsion, a wide range of emulsions can be used as long as the component that acts to bond the activated carbon particles and the base material is dispersed in the liquid in the form of particles. Included in the invented impregnating agent.

When the activated carbon particles are adhered to the base material such as gauze or non-woven fabric by the emulsion particles, since the adhesive particles are dispersed in the liquid in the form of particles, the activated carbon particles and the fiber surface of the base material are Since the adhesive only partially adheres, the water-absorbing function of the activated carbon surface and the fiber surface of the base material is not significantly impaired, and the flexibility of the bandage is maintained. On the other hand, when a solution type adhesive is used, the surfaces of the activated carbon particles and the base fiber are entirely covered with the adhesive, so that the functions of both are not significantly impaired, and the bandage Flexibility is also reduced.

The emulsion or latex used in the present invention is, for example, vinyl acetate resin emulsion, vinyl acetate / ethylene copolymer emulsion, acrylic emulsion, styrene / butadiene latex, polyisoprene latex, polybutadiene latex. Etc.

As described above, many synthetic polymer emulsions or latices are used, but since they are used as bandages, emulsions or latices that leave an odor even after being impregnated and dried are not preferable.

In order to impregnate the gauze or the non-woven fabric with the emulsion in which the activated carbon fine particles are dispersed, the gauze or the non-woven fabric may be dipped in the emulsion and squeezed to remove excess adherent liquid, or may be dried or evenly applied to the surface of the sheet. The amount of the activated carbon powder to be impregnated is preferably 10 to 100 g / m ² , and more preferably 30 to 50 g / m ² in consideration of deodorizing property and the influence on the affected area.

Furthermore, malic acid, L-ascorbic acid or citric acid must be attached to one side of the dressing of the present invention. Amine is considered to be the main component of the malodor generated from suppurated pus. Activated carbon alone is an excellent adsorbent for amines, but the human sense of smell is very sensitive, and even a slight odor is often uncomfortable. Therefore, amines must be completely removed by adsorption. Citric acid is an organic acid with a pungent odor. However, when a small amount is attached to activated carbon and retained, only a slight odor is felt because it is strongly adsorbed in the pores on the surface of activated carbon.

Since organic acids are highly reactive with basic amines, when they are used by being impregnated with activated carbon, the adsorptivity for amines is significantly improved. Further, when the organic acid is adsorbed and retained on the activated carbon, there is an advantage that the odor of the acid is hardly felt.

Since organic acids are irritating when they come into direct contact with the skin, it is necessary to take care not to directly touch the inflamed lesion. A mild acid is preferable even when it is used so as not to come into direct contact with it. Considering the adsorbability of amines and these points, malic acid, L-ascorbic acid or citric acid is suitable for the purpose of the present invention. Further, the amount of the organic acid impregnated is preferably 1 to 10 g / m ^2, more preferably 3 to 5 g / m ² in consideration of the irritation to the skin and the influence on amines.

Therefore, organic acids are irritating when they come into direct contact with the skin, and the affected area is particularly sensitive. Therefore, avoid the part of the bandage that comes into direct contact with the skin, and do not come into contact with the skin of the bandage. It needs to be attached only to one side, the opposite side, which comes into direct skin contact.

In order to attach these organic acids to the gauze or the non-woven fabric, after the activated carbon is impregnated in the gauze or the non-woven fabric, the organic acid can be attached by spraying an aqueous solution of the organic acid on one side of the bandage. I can.

The bandage of the present invention may use a strip-shaped strip as a raw material in advance, or a wide sheet may be impregnated with activated carbon and then an organic acid may be attached to one side thereof to form a strip or strip. It may be cut into strips and wound into rolls.

Since the bandage of the present invention is as flexible and extremely thin as a conventional bandage, it can be used just like an ordinary bandage wherever an ordinary bandage can be used. Since not only activated carbon but also organic acid is attached, it is particularly suitable for adsorptive removal of amines, which are the main components of the malodor generated from suppurated affected areas.

Hereinafter, the present invention will be described in more detail with reference to examples.
