[Industrial application field]

TECHNICAL FIELD The present invention relates to an emergency bandage containing a drug such as a germicidal disinfectant. [0002]

[Conventional technology]

A commonly used simple emergency bandage is made by attaching gauze impregnated with a sterilizing disinfectant or wound treatment agent to an adhesive sheet with ventilation holes, and when in use, peel off the release paper on the back and apply the gauze to the wound. It is designed to be used in [0003] However, in these conventional products, because the gauze is impregnated with a chemical solution in advance, the chemical solution evaporates over time.
In addition, not only does it lose its effectiveness, but the gauze part is dry when applied to the local area, so there is a risk of damaging the wound, and there are disadvantages such as making people feel pain when using it. . [0004] Also, an emergency bandage having a blister portion in which a drug is sealed with a drug coating film, and in use, the pad is impregnated with the drug by pressing the blister portion with a finger to break the drug coating film. is also known (Jikko 54)
-23197, U.S. Pat. No. 3,297,032). [0005]

[Problem to be solved by the invention]

However, in this type of emergency bandage, the blister part has a smooth surface, so when the blister part is pressed, the force is dispersed over the entire blister part, and the entire pressing part becomes irregularly depressed. For this reason, it was very difficult for the blister portion to reach and destroy the drug-coated membrane. [0006] Furthermore, even if the drug coating film is destroyed due to an increase in the internal pressure of the blister part, the breakage point will be a tangent between the blister part and the drug coating film, and the drug will move to the outer edge of the pad or outside the pad. However, there was a problem that the effect was impaired. [0007] US Pat. No. 4,117,841 discloses that a liquid-impermeable sheet (or liquid-impermeable layer) is formed by forming a drug-holding space on the central lower surface of an adhesive-coated bandage strip. A bandage is described in which a liquid-permeable sheet is provided through the bandage, a plastic tooth-like protrusion is provided on the lower surface of the bandage strip in the space, and a drug is filled in the space. [0008] When using this bandage, the sheet is pressed against the protrusion with a finger, the sheet is broken and the medicine is dripped directly onto the wound, and then the bandage is applied to the wound. The operation of destroying the sheet by pressing it against the surface may damage or injure your fingers due to the sharp parts of the protrusions, and some of the chemical solution may adhere to your fingers when the sheet is destroyed.
Furthermore, when the medicinal solution is subsequently applied to the wound, some of the medicinal solution drips from the wound and is wasted. In addition, the basic drawback of this bandage is that the bandage remains with protrusions.
In addition, since it is applied to a wound with its sharp point facing the wound, there is a risk that the protrusion will further damage the wound, and even if this is not the case, it has the disadvantage of being extremely uncomfortable to use. [0009] The present invention solves the above-described drawbacks of the prior art. [0010]

[Means to solve the problem]

That is, the emergency bandage of the present invention consists of an adhesive sheet attached with a pad and a release sheet, and the release sheet includes:
A blister portion whose lower surface is sealed with a drug coating film and which contains the drug is provided on the pad, and the blister portion is provided with a concave projection. [0011] When the emergency bandage of the present invention is used, the blister part is pressed with a finger to destroy the drug coating film by the concave projections of the blister part and move the drug to the pad. It is very easy to operate by placing your finger in the recessed part of the concave protrusion of the blister part, and since the protruding part is harder in shape than the surrounding part, if you press it from above, the protruding part will change its shape. The drug can reach the drug-coated membrane without breaking and easily and reliably destroy the drug-coated membrane at the desired location, which generally corresponds to the center of the pad. to the desired location without any waste. [0012] After the drug is transferred to the pad in this manner, the release sheet having the drug coating film and the blister portion provided with the concave protrusions is removed from the adhesive sheet. Further, since only the adhesive sheet having the pad with the drug applied thereto is applied to the wound, there is no danger or discomfort during use. [0013] Regarding the agents used in the present invention, chlorhexidine gluconate, benzalkonium chloride, chlorxylenol, acrinol, thianthol, dequalinium chloride, sulfisomidine, sulfamine, nitrofurazone, boric acid, homosulfamine, triclocarpane are used as disinfectants. Zinc oxide as a wound astringent healing promoter, etc.
Pyridoxine hydrochloride, tocopherol acetate, pyridoxine civalmitate, etc. Hemostatic agents include naphazoline hydrochloride,
Anti-inflammatory agents such as zinc sulfate and ephedrine hydrochloride; steroids such as prednisolone, dexamethasone, and cortisone acetate; glycyrrhetin and lysozyme chloride; and antihistamine agents such as chlorpheniramine maleate and diphenhydramine hydrochloride. [0014] Local narcotics include acupuncture, ethyl aminobenzoate, procaine hydrochloride, dypcaine hydrochloride, tetracaine hydrochloride, diethylaminoethyl valbutylaminobenzoate and the like. [0015] Depending on the purpose, these drugs can be used singly or as a combination of multiple drugs, and the drug may be in the form of a solution, or
It may be in any form as long as it is fluid, such as ointment, grease, or powder. [0016] The pressure-sensitive adhesive sheet may be one that is commonly used, and the pad may be made of absorbent cotton, various types of cotton, nonwoven fabric, etc., and may have a shape with a concave central portion as appropriate. Further, the back surface may be waterproofed by a normal method. [0017] The release sheet is molded from a material such as vinyl chloride resin or other synthetic resin, and has a circular, oval, or rectangular blister section in the center, and slits at the ends to make it easier to turn over the release sheet. It is good to have a [0018] A drug coating film is sealed on the lower surface of the blister of the release sheet to prevent the drug from coming into contact with the pad until use. As the drug coating membrane, a membrane that is easily destroyed, such as aluminum foil or glassine paper, is used. The coating film may be large enough to protect the drug) and may be provided on the entire lower surface of the release sheet. [0019]
