Description

Adhesive Sheet for Cataplasma Patch Drug

The present invention relates to a poultice agent, and more particularly, to a contact pouch for adhering a single-piece poultice agent to skin, and to an integrated pouch for a single-type poultice agent having improved air permeability.

Patch agents (transdermal patches), which allow a drug to be administered through the skin by attaching a patch containing the drug to the skin, have been widely applied to drugs that can be applied through the skin route.

Patch agents are largely distinguished by plaster and papasma cataplasma, with the former applying a warning (dry) agent and the latter with the purpose of alleviating the skin flare, which is a disadvantage of the warning agent It is a wet chemical with a high water content.

Examples of the prior art related to the wetting agent include a wetting agent of Korean Patent No. 10-0245835 (registered on December 01, 1999), Korean Patent Application No. 10-2000-0060794 (published on October 16, 2000) "Patent No. 10-0463958 (registered on December 20, 2004)," Production method of the puffing agent and the puffing agent ", Registered Utility Model No. 20-0264428 (registered on January 31, 2002) Quot; Puffing Agent with Adhesive Surface ", Registered Utility Model No. 20-0338181 (Registered on Dec. 30, 2003), Korea Registered Utility Model No. 20-0365596 (Registered trademark) of Korean Registered Utility Model No. 20-0373228 (registered on 2005. 05. 05), and the like.

Fig. 4 is a schematic cross-sectional view of a general wetting agent widely used in the past.

As shown in FIG. 1, a general wetting agent 100 includes a chemical patch 110, a close-up cloth 120, and a release paper 130.

The medicine patch 110 is a patch for holding a medicine to be applied to the skin, and the adhesive wet chemical 112 is applied on one side of the entire surface of a bubble 111 (base fabric, e.g., nonwoven fabric) that provides an adhesive base surface.

The adhered cloth 120 is a kind of adhesive tape for holding and protecting the medicine patch 110 in a state adhered to the skin (an affected part). The adhered cloth 120 is provided on one side of the bubble 121 (e.g., nonwoven fabric) And is formed in a size larger than the size of the medicine patch 110 and covers the entire surface of the medicine patch 110. A margin portion remaining on the periphery is attached to the skin , Thereby protecting the medicine patch 110 while keeping it attached to the skin.

The release paper 130 protects the medicine 112 of the medicine patch 110 and the adhesive 122 of the close-up pouch 120 from being exposed to the outside during storage and transportation of the integral type poultice, It is a sheet of paper or a kind of material which can be easily removed to expose the medicine 112 of the medicine patch 110 and the pressure sensitive adhesive 122 of the contact pouch 120.

Such a wetting agent 100 may be provided by separating the medicinal patch 110 and the adhered bodily 120 separately from each other. However, in the case of the separate type, when the user accurately positions the medicinal patch 110 at the center of the adhered bodily 120 In recent years, a "monolithic poultice agent" has been developed and used in which the chemical patch 110 is attached to the contact pouch 120 in a state of being attached to the user.

One of the problems of the tightly bonded bubble 120 used in the conventional integrated type wetting agent as described above is that even if a breathable material (for example, a breathable nonwoven fabric) is applied to the bubble 121 providing the adhesive surface in the tightly- The pressure sensitive adhesive 122 applied to the entire surface of the adhered cloth 120 closes the air hole of the bubble 121 and thus the ventilation to the skin is weak and skin redness can be caused and the diffusion of the drug into the affected part And it is possible to cause pain (desorption pain) when attaching and detaching the close-up cloth 120 due to excessive adhesive force.

The object of the present invention is to improve the shortness of air permeability of the tightly closed fabric used in the conventional single-unit type poultice as described above.

It is an object of the present invention to provide a pressure-sensitive adhesive which is not applied to the entire surface of air-permeable bubbles and which is coated with a pressure-sensitive adhesive in an alternating manner The pressure-sensitive adhesive can relieve the air permeability of the air-permeable bubbles from being lowered, thereby making it possible to smoothly introduce air into the skin, thereby reducing adverse effects of skin flare, improving drug diffusion and improving drug efficacy, To relieve desorption pain.

According to the present invention, an integrated canister for a single-piece poultice is provided.

According to the present invention, the tightly bonded foam for a single-layered wetting agent is formed in a size larger than the size of the drug patch and adheres to the entire surface of the drug patch, and the remaining margin around the skin adheres to the skin, Adhered and protected.

According to the present invention, a pressure-sensitive adhesive is applied to an air-permeable base fabric that provides an adhesive surface, wherein the pressure-sensitive adhesive is not applied to the entire surface of the air-permeable bubble, Coated areas and linear non-applied areas having a constant width are alternately arranged.

Preferably, the linear shape of the application region and the non-application region is "S-shaped" or "

Preferably, the area ratio of the application area to the non-application area in the bubbles ranges from 2: 1 to 5: 1.

According to the present invention, the pressure-sensitive adhesive for a unitary-type wetting agent is applied in such a manner that the pressure-sensitive adhesive is not attached to the entire surface of the air-permeable bubble but linearly coated areas having a constant width and linear non- Therefore, by adhering the drug patch to the skin with the tightly closed cloth of the present invention, it is possible to smoothly flow through the non-application region of the pressure-sensitive adhesive, thereby reducing side effects of skin flare, Not only can it promote diffusion, but also has the effect of relieving the desorption pain which may be caused by excessive adhesion.

Figure 4 is a cross-sectional view of a conventional monolithic pandemic.

Hereinafter, referring to the accompanying drawings, the integrated foam for a single unit type foaming agent according to the present invention will be described in detail. The following specific examples are merely illustrative of the tightly packed product of the present invention, and do not limit the scope of the present invention.

According to the present invention, the contact type foil for a single-layer type foaming agent is a contact type foil for application to a single-type fungicide provided with a chemical patch attached to an adhesive foil without providing the adhesive foil in a state separated from the chemical patch.

As described above, the single-piece type wetting agent 2 to which the present inventive close-up bobbin 1 is applied is composed of the drug patch 3 coated with the medicine 3b on one side of the bubble 3a, (1b) of the present invention adhered to the entire surface of the drug pad (3) so as to adhere the peripheral margin to the skin, the drug (3b) of the exposed drug patch (3) And a release paper 4 for protecting the pressure-sensitive adhesive 20 of the tightly-wound cloth 1.

The adhesive foil 1 according to the present invention has a constitution in which a pressure-sensitive adhesive 20 is applied to one surface of an air-permeable bubble 10, which basically forms an adhesive surface.

The material of the bubble 10 is not particularly limited as long as it is made of air permeable cloth. For example, a widely known air-permeable nonwoven fabric can be applied according to the present invention. As the adhesive 20, Known acrylic or rubber pressure-sensitive adhesives widely used as pressure-sensitive adhesives can be applied according to the present invention.

According to the feature of the present invention, the adhesive foil 1 of the present invention has a structure in which the adhesive 20 is not applied to the entire surface of the air-permeable bubble 10, and the linear coating area 21 having a constant width, Coated non-application areas 22 are alternately arranged.

That is, when the pressure-sensitive adhesive 20 is applied to the breathable bubble 10, the pressure-sensitive adhesive 20 seals the air holes formed in the breathable bubble 10 to lose the breathability of the breathable bubble 10, 10, the use of the air-bubble 10 with air bubbles becomes substantially meaningless.

However, in the adhered fabric 1 of the present invention, the non-applied region 22 in which the adhesive 20 is not applied in the air-permeable bubble 10 is applied between the application regions 21 to which the adhesive 20 is applied The air permeability of the air-permeable bubble 10 is maintained at least in the non-applied region 22 because the adhesive 20 is repeatedly present in the non-applied region 22 linearly and repeatedly, .

Therefore, when the integral type puffer agent 2 is applied to the skin using the contact pouch 1 of the present invention, in the state where the margin portion of the contact pouch 1 remaining around the drug patch 3 adheres to the skin, The uncoated region 22 existing at regular intervals becomes an ecology that is not adhered to the skin, and a fine gap between the contact pouch 1 and the skin, as well as the air hole of the air-permeable bubble 10, It is possible to allow the air to pass therethrough, so that the skin redness due to the skin application of the pressure-sensitive adhesive can be alleviated.

In addition, in the non-applied region 22 at a predetermined interval on the upper surface of the chemical patch 3, since outside air can be supplied to the chemical patch 3 through the air hole of the air-permeable bubble 10, The diffusion of the applied diffusible drug can be promoted and the effect of the drug can be enhanced.

In addition, since the non-applied region 22 existing at regular intervals is prevented from being excessively adhered to the skin, it is possible to alleviate the desorbing pain that may occur when the contact pouch is attached to and removed from the skin.

The application region 21 and the non-application region 22 applied to the tightly bonded cloth 1 of the present invention suffice to be arranged in a linearly alternating manner, and the shape of the linear region is not particularly limited. For example, as shown in FIG. 2 It may be of the same S type or a one-figure type as shown in FIG.

The relative width (linear width) of the applied region 21 and the non-applied region 22 occupied by the tightly bonded blanks 1 of the present invention is set such that the tightly bonded blanks 1 of the present invention are in contact with the tightly- It is possible to appropriately select the size depending on the size of the tightly-bonded cloth 1 in the present invention and the type of the applied pressure-sensitive adhesive 20 (strength of adhesive force) The area ratio of the application region 22 can be selected in the range of 2: 1 to 5: 1.

At this time, if the ratio of the non-applied region 22 is excessively high, the skin adhesion of the integrally-formed foam 2 may be deteriorated. If the ratio is too low, the improvement in air permeability may be insufficient.

The method for manufacturing the tightly bonded fabric 1 according to the present invention is not particularly limited. For example, a scraper in the form of a comb, such as a comb, may be used while transferring an original plate coated with a pressure- scraper) is linearly scratched on the base film in a state in which the adhesive is linearly (for example, S-shaped or one-shaped) in a state in which the coated region and the uncoated region are alternately present A method in which the air-permeable nonwoven fabric 10 is covered on the original plate and the adhesive 20 on the original plate is transferred to the air-permeable nonwoven fabric 10 can be applied. As a result, .

3: drug patch 3a: drug patch patch
3b: drug 4: release paper
10: base cloth of the adhesive cloth 20: pressure-sensitive adhesive
21: application region 22: non-application region
