Description

[0001] The present invention relates to a dressing material,

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.

As shown in FIGS. 1A and 2, a dressing material 10, which is easy to separate according to an embodiment of the present invention, includes a release sheet 100 having a predetermined width and a predetermined length, And a pressure sensitive adhesive sheet 200 on which an adhesive layer 210 is formed to be adhered to the adhesive sheet 200. The release sheet 100 corresponding to the upper side of the adhesive sheet 200 is removably cut A releasing gripping portion 110 having a predetermined area is formed.

The protruding portion 111 protruding from the upper side of the release gripping portion 110 is formed to facilitate separation of the release gripping portion 110 and the adhesive sheet 200 from the release sheet 100. [ can do.

Accordingly, the dressing material 10, which is easy to separate according to an embodiment of the present invention, includes a release paper 100 having a predetermined width and length, and an adhesive sheet 200 attached to one side of the release paper 100 And a release grip unit 110 is formed which is cut off in a predetermined area in a release sheet 100 corresponding to one side portion of the adhesive sheet 200. As shown in FIG.

At this time, a smooth coating layer is formed on one side of the release paper 100, so that the adhesive sheet 200 can be easily attached and detached.

The release grip 110 is formed on the release sheet 100 corresponding to the upper side of the back surface of the adhesive sheet 200. [

The release gripper 110 is formed so that one side thereof is adhered to and peeled off from the adhesive layer 210 of the adhesive sheet 200 and is cut at one side of the release paper 100 facing the upper side of the adhesive sheet 200 And is separated from the release paper 100.

Here, the cut-off is cut off as shown in FIG. 2 and can be separated. However, as long as the user does not intend to artificially separate the cut-out portion, the cut-type holding portion 110 is caught in the release paper 100 It says.

Further, when the adhesive sheet 200 is peeled off from the release paper 100 by further forming the protruding portion 111 protruding upward from the upper side of the release gripper 110, So that the release grip 110 can be peeled off from the release paper 100 after the protrusion 111 is caught.

The release gripper 110 is a part of the release paper 100 and may be made of the same material as that of the release paper 100 and a thin material such as a film type in which a smooth coating layer is formed.

Since the release gripper 110 is formed in the release paper 100, it is formed so as not to be exposed to the outside of the adhesive sheet 200, thereby improving the appearance of the dressing material itself. We expect effects.

As shown in FIG. 1B, a plurality of easy-to-separate dressing members according to another embodiment of the present invention may be arranged. Alternatively, a separate dressing member according to another embodiment of the present invention may be formed at a predetermined angle 1B and 1C are cross-sectional views of the dressing material according to an embodiment of the present invention. As shown in FIG. 1B and FIG. 1C, the dressing material is indicated by a dotted line so that the dressing material can be inclined at a predetermined angle, It is to be understood that the invention is not limited to the disclosed embodiments.

3, the shape of the mold release gripper 110 may be a trapezoidal shape (see FIG. 3A), a semicircular shape (for example, (Fig. 3 (b)), and a tear shape (Fig. 3 (c)).

In the case of the adhesive sheet 200, an adhesive layer 210 to be adhered to the release paper 100 may be applied to the back surface of the release paper 100, which is a surface attached to one side of the release paper. That is, the applied adhesive layer 210 is formed and attached to the release paper 100, and the adhesive layer 210 is adhered to the affected part of the skin.

That is, the adhesive sheet 200 is formed to have a small thickness and an adhesive layer 210 is formed on one side of the release paper 100 opposite to the other side of the release paper 100 to be peelably adhered to the other side of the release paper 100 And the adhesive sheet 200 peeled off by the adhesive layer 210 formed on one side may be formed to adhere to the user's skin.

On the other hand, the adhesive sheet 200 may be realized as a hydrocolloid adhesive sheet or a polyurethane foam adhesive sheet type in which demand is increasing in recent years. The hydrocolloid adhesive sheet is a form in which hydrophilic hydrocolloid polymers are dispersed on a hydrophobic rubber-like matrix-adhering surface having adhesive strength, and a polyurethane foam adhesive sheet is formed by dispersing polyethylene glycol, isocyanate, and catalyst on a hydrophobic urethane- And water are mixed and dispersed. The hydrocolloid adhesive sheet and the polyurethane foam adhesive sheet have wicking protection ability and excellent adhesive force due to hygroscopicity and maintenance of the wetting environment, and they are now widely used. Therefore, Is omitted.

4 (a), a dressing material having a pressure-sensitive adhesive sheet 200a to which a pad (gauze) is attached on the back surface may be used as another embodiment, and as shown in FIG. 4 (b) A dressing material having a shape having a plurality of elastic colloid type pressure sensitive adhesive sheets 200b and having a thin edge portion may also be used. Since such a dressing material having a thin-walled edge is a known technique, It will be omitted.

4A, the pad 300a provided on one side of the adhesive sheet 200a is attached to the adhesive layer 210 of the adhesive sheet 200a, It functions to protect the affected part and its surroundings while being contacted.

Further, it is preferable that the protective sheet 200 is formed in various shapes, and various patterns or characters are printed to enhance aesthetics, while being formed in the same color as the color of the skin so as not to feel a sense of sheen when attached to the skin. That is, the shape of the adhesive sheet 200 can be formed into various shapes according to the needs of the consumer.

The use of the dressing material according to one embodiment of the present invention is as follows.

First, a release sheet 100 having a predetermined width and length is rolled up in a rolled state in a state where the adhesive sheet 200 is attached, and is packaged and flowed in a packaging box.

In order to separate the adhesive sheet 200 adhered to one side of the release paper 100, the user pushes the side of the adhesive sheet 200 and the back side of the release gripper 110 formed in the release paper 100 with fingers, And then peels the surface of the pressure-sensitive adhesive sheet 200 while separating the pressure-sensitive adhesive sheet 200 from the pressure-sensitive adhesive sheet.

When the protruding portion 111 of the deformed grip portion 110 protruded upward is peeled by a finger and pulled to one side in order to peel off the adhesive sheet 200 adhered to the other side surface of the release paper 100, So that the adhesive sheet 200 and the release grip 110 are exposed while being peeled off from the release paper 100.

At this time, when the protruding portion 111 is gripped with the fingers, the adhesive sheet 200 is prevented from touching the fingers.

After the adhesive sheet 200 is separated from the release paper 100 so that the adhesive sheet 200 is positioned on the affected part, the adhesive sheet 200 is attached to the periphery of the affected part as it is.

Then, the adhesive sheet 200 is attached to the affected part of the back of the hand. At this time, the protruding portion 111 of the release grip 110 is gripped by attaching the portion to which the release grip 110 is not attached, The mold releasing portion 110 is completely separated from the sheet 200 and then pressed against the surface of the adhesive sheet 200 to be adhered to the affected portion.

The upper end of the adhesive sheet 200 is folded so as to peel off the releasing gripping portion 110 which is adhered to the back surface of the adhesive sheet 200 and touches the skin, To be exposed to the outside.

When the mold releasing portion 110 is exposed, both ends of the lower portion of the mold releasing portion 110 opposed to the protruding portion 111 are separated from the pressure-sensitive adhesive layer 210, and the pressure-sensitive adhesive sheet 210 is peeled off.

When the release gripper 110 is peeled off, the folded portion is spread again so that the adhesive layer 210 is brought into contact with the skin, thereby fully adhering the adhesive sheet 200 to the skin.

In order to peel off the adhesive sheet 200 from the release paper 100, the surface of the release gripper 110 and the adhesive sheet 200 are peeled and peeled off. In this process, the adhesive sheet 200 is adhered to the skin The adhesive sheet 200 can be prevented from being contaminated on the back surface provided with the layer 210 and the pressure sensitive adhesive sheet 200 can be prevented from being stuck to the adhesive sheet 200 while gripping the releasable gripper portion 110 attached to the adhesive sheet 200. [ The adhesive layer 210 of the adhesive sheet 200 is not in contact with the hand at all, so that it is possible to fundamentally block the contamination.

Particularly, since there is no protruded portion of the releasing grip portion 110 outside the adhesive sheet 200, there is almost no possibility that the adhesive sheet 200 is separated from the adhesive sheet 200 without being caught in surrounding objects or clothes when stored or carried , The adhesive sheet 200 can be safely protected even during storage.

FIG. 5 is a block diagram showing a method of manufacturing a dressing material according to an embodiment of the present invention. FIG. 6 is a schematic view showing a method of manufacturing a dressing material according to an embodiment of the present invention, 7 is a schematic view showing a method of manufacturing a dressing material which is easy to separate according to another embodiment of the present invention.

5 to 6, a method S10 of manufacturing a dressing material that is easy to separate according to an embodiment of the present invention includes a raw material input step S100, a release paper cutting step S200, a joining step S300, (S400). As shown in FIG. 7, the method S10a for easily separating dressing material according to another embodiment of the present invention may include a step S100 for selectively inputting a raw fabric and a cutting step (SA100) may be included in the finishing step (S200), and the finishing step (S500) after the cutting step (S400) may further include the winding step (SA500) and the scrapping step (SB500).

6 and 7 are schematic explanatory diagrams for explaining the present invention in an easy-to-understand manner. The arrangement or up-and-down position of each processing apparatus can be fluid, and in particular, , But it is not applied to the production process, and it is possible to change the vertical position in consideration of the production process efficiency.

Hereinafter, a method of manufacturing a dressing material according to an embodiment of the present invention will be described.

First, the raw fabric applying step S100 is a step of supplying the pressure sensitive adhesive sheet 210 with a predetermined adhesive force to one side of the pressure sensitive adhesive sheet T1. May be formed.

Further, the pressure sensitive adhesive sheet fabric T1 is generally supplied in the market, and is supplied in consideration of the shape and size of the product to be produced, and the color and texture of the surface may vary depending on the characteristics of the product.

Further, the thickness and the adhesive force of the adhesive layer 210 can be determined according to the characteristics of the product to be manufactured.

Next, in the cutting step S200, the cutter C1 is used to cut the outer edge of the release grip 110 in the releasing paper 100 before the release roll T2 is put into the next process, Is cut off.

This improves the prior art in which the release paper 100 and the adhesive sheet 200 are separated from each other using an intermediate member between the release paper 100 and the adhesive sheet 200. The release paper is cut in a cutting step S200, Instead of using the conventional intermediate member, the release gripper 110 capable of functioning as an intermediate member is formed on the release paper 100 itself, thereby eliminating the need for the intermediate member material and intermediate member injection process, thereby improving the productivity and economy Process technology.

For the sake of brevity, the term "cut" refers to a state of being cut off to a degree that it can be easily detached, and as long as the user does not intend to artificially separate the cutter, Quot;), "

In addition, the shape of the release gripper 110 may be formed in various release papers which can be easily gripped by the user and can be easily separated (see FIG. 3).

The outer shape of the protrusion 111 may be cut off and the protrusion 111 may be more easily gripped by the user than the outer shape of the protrusion 111. [ So that separation between the release paper 100 and the adhesive sheet 200 can be facilitated.

Next, the joining step S300 is a step of joining the pressure-sensitive adhesive sheet 210 to the pressure-sensitive adhesive sheet 210 using the pressure bonding apparatus P1, Is a step of attaching and releasing a release paper roll T2 on which the release gripper 110 supplied in step S200 is cut.

The pressing apparatus P1 may adopt a method of vertically pressing a cylindrical roller, and the combined pressing strength between the release paper 100 and the pressure-sensitive adhesive sheet 200 has a bonding force enough for the user to use.

In the next cutting step S400, the adhesive sheet is cut into a desired shape, for example, a disk-shaped (exemplified) shape using a cutting device P2, and the release paper 100 and the release gripper 110 And then cut to form one side face of the pressure-sensitive adhesive sheet 200. Then, when the pressure-sensitive adhesive sheet 200 except for the part formed in the disk-shape is separated, the pressure-sensitive adhesive sheet 200 remain in the release paper 100. [ Thus, the dressing material can be easily separated according to an embodiment of the present invention.

The finishing process S500 includes a winding process SA500 in which the product is completed and wound in a roll form through the rotating roller R3 and the scrap process in which the remaining portion of the product other than the component forming the product is collected through the collecting roller R4 (SB500).

The winding process (SA500) may be rolled up by a rotary roller (R3), sold in roll type, and processed again to a predetermined size and then packaged and sold.

The scrapping process (SB500) recovers the scraped scraps separated from the adhesive sheet (200) to determine whether or not the scrap can be recycled and processes the scrap.

7, a method for manufacturing a dressing material S 10 a according to another embodiment of the present invention is a method for manufacturing a dressing material S 10 a in which a raw material supplying step S 100 and a release paper are cut between the additive member S 200 and the cut- And an addition step (SA100) is further included.

The additive member injecting step (SA100) is to place the additive member (TA), which is a gauze or a pad, selectively cut to a predetermined length by using the additive device R2, on the adhesive sheet fabric.

That is, the addition member TA may be cut in the shape of a pad (gauze) 300a in FIG. 4A, a liquid phase 300b in the hydrocolloid type in FIG. 4B, The material depends on the characteristics of the dressing material.
