Description
The present invention relates to a dressing material which is easy to separate and a method for manufacturing the dressing material. More particularly, the present invention relates to a dressing material which can be separated from a release paper, The sheet can be sanitarily separated and adhered to the wound area, and then peeled off from the adhesive sheet through the cut area of the release sheet to reduce production materials and shorten the manufacturing process, while maintaining the convenience of use And a method for manufacturing the dressing material.
Generally, a dressing material is widely used for treatment while protecting skin wounds such as minor burns, wounds, trauma, and the like. That is, the dressing material reduces the evaporation of heat from the wound surface and the loss of moisture, thereby preventing further contamination and providing a function of reducing bacterial growth in the wound.
Such a dressing material has a structure in which an adhesive sheet is attached to the top surface of the release paper, and the adhesive sheet is detached from the release paper to attach the attachment surface formed on the bottom surface of the adhesive sheet to the wound area.
However, in order to separate the adhesive sheet from the releasing paper, one side of the adhesive sheet is detached and attached to the wound area. In this process, the user may grasp the adhesive sheet and thus contamination may occur. In addition, since the thickness of the pressure-sensitive adhesive sheet is gradually becoming thinner, the operation of separating the pressure-sensitive adhesive sheet from the release paper is also inconvenient and the ease of use is reduced. Thus, the thickness of the pressure-sensitive adhesive sheet gradually becomes thinner to further ensure the wearing comfort and the activity of the patient with the pressure-sensitive adhesive sheet.
Thus, in order to easily separate the pressure sensitive adhesive sheet from the release paper, a dressing material having a separation pad between the release paper and the pressure sensitive adhesive sheet, that is, a medical band is provided. For example, Korean Utility Model Registration No. 20-0439156 is representative.
With reference to this publication, the handle is gripped to separate the protective sheet from the release sheet, and the separated release sheet is separated from the protective sheet again while attaching to the wound site.
According to the above configuration, since the handle portion of the separated release sheet can be gripped without holding the protective sheet, the protective sheet can be detached from the release sheet and attached to the wound site, so that it is possible to conveniently and safely prevent the secondary bacterial infection .
However, there is a problem in that it is not possible to reduce the production material and shorten the manufacturing process since the separating release paper which is an intermediate separating member is used to separate the protective sheet sanitarily from the release paper.
Korean Patent Registration No. 10-1281353, entitled " Medical dressing material and its manufacturing method ", which is equipped with an auxiliary release paper, is not only convenient for separating the pressure-sensitive adhesive sheet from the release paper, It is possible to easily separate the auxiliary release papers from the sheet, thereby improving the ease of use, preventing contamination of the pressure-sensitive adhesive sheet during separation from the release papers or separating the auxiliary release papers, The present invention proposes a medical dressing material and a method for manufacturing the same which can improve the appearance and convenience of carrying and storing because the secondary release paper is not exposed to the outside.
However, it is also necessary to prevent contamination of the adhesive sheet by minimizing separation of the auxiliary release sheet from the adhesive sheet while the auxiliary release sheet is protruded to the outside of the adhesive sheet, so that the auxiliary release sheet is used. The manufacturing process can not be shortened.
The same inventor of the present invention has Korean Patent Publication No. 10-2014-0040195 entitled "medical dressing material ", which is provided with an auxiliary release sheet to facilitate separation of the adhesive sheet from the release sheet, The present invention proposes a medical dressing material capable of minimizing separation of the pressure sensitive adhesive sheet from the pressure sensitive adhesive sheet and minimizing separation of the pressure sensitive adhesive sheet from the pressure sensitive adhesive sheet to minimize the size of the auxiliary release paper. However, there was.
Disclosure of the Invention The present invention has been devised in view of the above problems and needs, and it is an object of the present invention to provide a releasable gripping part separable from a release paper to hygienicly separate the adhesive sheet from the releasing paper, It is possible to easily peel off the releasing grip portion from the back pressure sensitive adhesive sheet to improve ease of use and to prevent contamination of the pressure sensitive adhesive sheet during separation from the release paper to prevent secondary bacterial infection on the wound area, And it is an object of the present invention to provide a dressing material which is easy to carry and store, and which is easy to separate as well as improved appearance, and a method of manufacturing the dressing material.
According to an aspect of the present invention, there is provided a dressing apparatus comprising: a release sheet having a predetermined width and length; and a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer formed on one side of the release sheet, And a releasing gripping portion having a predetermined area removably cut off is formed on the release sheet corresponding to the upper side of the adhesive sheet.
In addition, it is characterized in that a projecting portion protruding from the upper side of the releasing grip portion is formed so that it is easier to peel off the releasing grip portion and the pressure-sensitive adhesive sheet in the releasing position.
According to the easy-to-separate dressing material and the manufacturing method thereof according to the embodiment of the present invention, the production material can be saved and the manufacturing process can be shortened, which is economical advantage.
Further, since the user's hand is not in direct contact with the adhesive layer of the adhesive sheet, contamination of the adhesive sheet can be prevented, and secondary bacterial infection to the wound area can be prevented.
Further, since the mold gripping portion is not exposed to the outside of the pressure sensitive adhesive sheet, there is an advantage that it is convenient to carry and store in addition to the appearance improvement.
