Abstract

The utility model discloses a take off no remaining plaster after, include: a base layer; a drug layer adhered below the base layer; a fibrous layer adhered beneath the drug layer; the glue film, the glue film bond in fibre layer below, just the glue film adopts no remaining glue film. The utility model discloses not only the gas permeability is good, the pliability is strong, with low costs, nontoxic nonirritant, has solved moreover that traditional plaster is easy to spill over around when using, the easy problem of remaining the medicine in the affected part.

Description

Plaster without residue after being taken off

Technical Field

The utility model relates to a plaster field, concretely relates to take off no remaining plaster after.

Background

The plaster is one of common means of traditional Chinese medicine clinical treatment, and the plaster on the market at present is generally divided into two types, one type is a hot melt adhesive plaster, the hot melt adhesive plaster has elasticity, and no medicine residue exists on the affected part after the plaster is used and removed. However, the allergy rate of the user group to the hot melt adhesive plaster is high and reaches 30-40%, the side effects of skin redness, itching, red rash or blister formation and the like are easy to occur after the plaster is attached, and the effective ingredients of the medicine can be firmly locked by the hot melt adhesive, so that the effective ingredients cannot be completely absorbed by the surface of the skin. The other one is the traditional old plaster, and the traditional old plaster is accepted by patients with the characteristics of quick response, strong permeability, extremely low allergy rate and the like. However, the conventional plaster is likely to stain the skin, clothes and sleeping bedding of other parts of a patient during use, and is not easy to clean. So the problem of drug residue in the traditional old plaster always troubles manufacturers.

Therefore, the plaster which has the advantages of good air permeability, strong flexibility, low cost, no toxicity and no irritation, can not pollute the skin, clothes and bedding for sleeping of other parts of a patient in the using process and has no residual effect after being uncovered is a problem to be solved by technical personnel in the field.

Disclosure of Invention

In view of this, the utility model provides a plaster without residue after being taken off.

In order to solve the technical problem, the utility model discloses following technical scheme has been taken:

a plaster without residue after being torn off is characterized by comprising:

a base layer;

a drug layer adhered below the base layer;

a fibrous layer adhered beneath the drug layer;

the glue film, the glue film bond in fibre layer below, just the glue film adopts no remaining glue film.

Preferably, the fiber layer is prepared by crossing and uniformly distributing a plurality of fibers and is bonded below the medicine layer through a strong adhesive.

Preferably, the base layer is made of rosin plaster matrix.

Preferably, the residue-free adhesive layer is double-sided mica tape.

Preferably, the double-sided mica tape ring is arranged on the periphery of the fiber layer and is bonded together.

Preferably, the plaster is provided with through vent holes, and the vent holes are uniformly distributed on the plaster.

Preferably, a smooth protective film is arranged below the adhesive layer and is closely adhered to the adhesive layer.

Preferably, the protective film is made of PU material.

The utility model discloses for prior art gain following technological effect:

the utility model adopts the fiber, has the characteristic of good tolerance, and can effectively prevent the drug residue after the plaster is taken off. The double-sided mica tape is an adhesive tape without residue after being taken off, and can effectively prevent colloid residue after the plaster is taken off. The utility model discloses simple structure, low cost is convenient for produce on a large scale.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, the utility model discloses a plaster without residue after uncovering, which comprises:

a rosin plaster matrix base layer 1; a drug layer 2; a fiber layer 3; no residual glue layer 4; a vent hole 5; and (5) protecting the film. The medicine layer 2 is adhered below the base layer 1; the fiber layer is adhered below the medicine layer and is prepared by crossing and uniformly distributing a plurality of fibers in a fishing net shape; the thickness of the fiber layer is less than that of the medicine layer; the adhesive layer is adhered below the fiber layer; the protective film is adhered below the adhesive layer; the air holes penetrate through the base layer and are evenly distributed on the base layer, and the diameter of each air hole is 60-100 um. The non-residue adhesive layer is a double-sided mica tape, the width of the double-sided mica tape is 1-1.5 cm, and the protective film is made of PU material.

When the patient needs to use the plaster, the protective film can be torn off for direct use.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
