Description
The present invention relates to a dressing material having adhesiveness, and more particularly, to an adhesive dressing material having excellent breathability and moisture permeability formed by lamination and a method for manufacturing the same.
Since the zoologist Winter has published a paper that suggests that keeping wounds moist is more beneficial to healing than drying wounds and causing scabs, the body fluids released from the wounds are dehydrated or dried (Wet dressing) in a wet environment has been emphasized and it has been confirmed that this method facilitates the treatment of wounds.
In general, it is necessary to take measures so that the wound can be cleared quickly while preventing the wound from being widened in the case of a wounds that have been torn by the skin. By attaching a dressing material such as a patch having a well- So as not to be opened further.
As the types of dressings for wound dressing currently in use, there are foam dressing materials using natural polymers such as polyurethane and chitosan, hydrogel, hydrocolloid, films made of natural and synthetic polymers, fibrous nonwoven fabrics made of natural and synthetic polymers Or a dressing material in the form of a woven fabric. Of these dressings for wound dressing, foam dressing materials are most widely used.
In the case of a foam dressing material, it can be classified into a foam dressing material composed entirely of foam, a sticking dressing material having a pressure-sensitive adhesive layer formed on a wound surface contact layer, and a sticking dressing material having a sticking film.
A foam dressing material composed of only a foam itself is most widely used because of its excellent ability to absorb and absorb initial exudates. However, in the case of the initial wound, which has a large amount of exudate, there is no great problem. However, in the middle and late period when the exudates are reduced and the wound is dried, a part of the foam forming the foam dressing material sticks to the wound, And sometimes a part of the newly formed new tissue is attached to the foam dressing material and comes off.
The adhesive dressing material in which the adhesive layer is formed on the wound surface contact layer can be usefully used for light scratches because acrylic or silicone adhesive is formed on the wound surface contact layer to a certain thickness. In this regard, Korean Patent Registration No. 10-1073048 discloses a pressure-sensitive adhesive prepared by forming a pressure-sensitive adhesive compounded with a silicone adhesive, an acrylic pressure-sensitive adhesive, a reaction inhibitor, etc. in a thickness of 20 to 95 μm on a wound- Quot; describes a foam dressing product. However, in this case, since an adhesive layer should be formed on the entire surface of the wound surface contact layer, it may be suitable for a surgical wound where a small amount of exudates are generated. However, a large amount of exudates such as burns and bed sores are generated, There is a limit to the use of the wound. In addition, if the pressure-sensitive adhesive is directly applied to the foamed dressing of the porous structure, there is a high possibility of blocking the pores capable of absorbing the exudates, and the pressure-sensitive adhesive or the like penetrates into the pores, There is a problem that it is difficult to apply the pressure-sensitive adhesive in one thickness.
In the case of the adhesive dressing material with the adhesive film attached thereto, the adhesive film having the adhesive layer formed on one side of the thin paper-like film made of soft synthetic resin can be attached to the surface of the object to be adhered. In addition, a plurality of through holes are formed in the adhesive film, so that exudates such as pus or blood, which are generated in the wound through the through holes, can be absorbed by the absorber . Conventionally, a plurality of through holes are formed by locally heating an adhesive film using an apparatus capable of finely controlling thermal energy such as an ultrasonic apparatus. That is, a constitutional article in which an absorber, a film and an adhesive layer are laminated is prepared, and penetrating holes are formed by irradiating ultrasonic waves only to specific areas where through holes are to be formed to melt specific areas (Korean Patent Registration No. 10-1320933). However, such a method is difficult to apply when the film is formed of a material that is not easily melted by heat. When a specific region of a film to be formed with a through hole is locally heated in a constitutional unit in which an adhesive layer, a film and an absorber are stacked, a specific region is melted down to form a through hole to form a through hole, The melt is pressed against the absorber, making it difficult to absorb the exudate. In addition, the heat-soluble material has such a characteristic that when it is melted by heat, its volume increases, and when it is cooled in a molten state, it shrinks to an unspecified form which is difficult to predict with decreasing volume.
In order to solve the above problems, in the present invention, a foam absorbent material having good water absorbency and moisture permeability, which is prepared separately, a leading film having a plurality of through holes formed vertically, and a breathable protective film, And an object of the present invention is to provide a good adhesive dressing material.
In order to achieve the above object, according to the present invention,

The foam film, the foam absorbent, and the adhesive film have a sequentially layered structure formed by lamination by heat and pressure. The adhesive film and the protective film have portions extending in four directions compared to the foam absorbent material, and direct lamination The present invention provides an adhesive dressing material comprising

In the manufacturing method of the present invention, it is preferable that the lamination step is carried out at a temperature of 150 to 230 DEG C and a pressure of 3.0 KGf / to 7.0 KGf /.
