Examples

Referring to fig. 1-4, embodiments of the present invention are shown.

As shown in fig. 1, the present embodiment provides a composite patch, which includes a film layer 1, a gauze layer 2, and an adhesive layer 3 connected in sequence, where the adhesive layer 3 contains a drug.

In this embodiment, the adhesive layer 3 is fixed in a plurality of small grids in the gauze layer 2 through the gauze layer 2, so as to reduce the fluidity of the colloid in the adhesive layer 3; when the whole patch is pressed, the gauze layer 2 can support the film layer 1, and the extrusion of the adhesive layer 3 is reduced. The patch structure can prevent or reduce the glue overflow phenomenon caused by extrusion or external temperature rise in the production, transportation and use processes of the patch, and can also shorten the product drying time in the production process and improve the production efficiency.

In this embodiment, the adhesive layer 3 is fused with the medicament and directly acts on the skin of the human body. The adhesive layer 3 in this embodiment includes, but is not limited to, pressure sensitive adhesive and hydrogel.

The pressure-sensitive adhesive is also called pressure-sensitive adhesive, pressure-sensitive adhesive for short. The pressure-sensitive adhesives are classified into rubber pressure-sensitive adhesives, polyacrylate pressure-sensitive adhesives, polyvinyl ether resins, polyurethane resins, polyisobutylene emulsion pressure-sensitive adhesives and the like according to the polymers of the pressure-sensitive adhesives, and the emulsion pressure-sensitive adhesives, particularly the acrylate emulsion pressure-sensitive adhesives, have special importance in China.

The acrylate pressure-sensitive adhesive is second to rubber and is most used, and is a copolymer of acrylate monomer and other ethylene monomers, which can be roughly divided into a crosslinking type and a non-crosslinking type. Since the glass transition temperature of the homopolymer is low (Tg: -20 ℃ C. to-700 ℃ C.), it is generally prepared by copolymerizing a flexible monomer which functions as an adhesive, a hard monomer which has a high glass transition temperature and is capable of imparting adhesiveness and cohesion, and a small amount of a functional group-containing monomer. The purpose of adding the functional group-containing monomer is to enable the pressure-sensitive adhesive to further improve its adhesive force, cohesive force and thermal creep resistance by crosslinking. The main characteristics of the acrylate monomer are as follows:

1. the addition of an antioxidant is hardly required, so that the coating has excellent weather resistance and heat resistance.

2. Since it is almost a single component, there are no phase separation and migration phenomena.

3. The transparency is good.

4. Good oil resistance.

5. Has no influence on skin, and is suitable for preparing medical adhesive tape.

Hydrogels are a class of very hydrophilic three-dimensional network-structured gels that swell rapidly in water and in this swollen state can hold a large volume of water without dissolving. Due to the presence of the crosslinked network, the hydrogel can swell and retain a large amount of water, the amount of water absorbed being closely related to the degree of crosslinking. The higher the degree of crosslinking, the lower the water absorption, which is very similar to a soft tissue, and the water content in hydrogels can be as low as a few percent, or as high as 99%. The hydrogel is neither a completely solid nor a completely liquid in its aggregated state, the solid being such that it can maintain a shape and volume under certain conditions, and the liquid being such that a solute can diffuse or permeate from the hydrogel.

As a material having high water absorption and high water retention, hydrogels are widely used in various fields such as: drought resistance in arid regions, facial masks, antipyretic patches and analgesic patches in cosmetics, and can also be used as antistaling agents and thickening agents in foods, drug carriers in medical treatment and the like.

Therefore, both pressure-sensitive adhesives and hydrogels are widely used in medical treatment, and thus any adhesive layer 3 having a drug carrier can be safely applied to the skin. The adhesive layer 3 in this embodiment is preferably a pressure sensitive adhesive widely used in medical supplies, and is not limited in other embodiments.

In some embodiments of the utility model, the thickness of the adhesive layer 3 is 0.02mm to 2 mm.

In this embodiment, the thickness can ensure that the amount of the drug in the adhesive layer 3 is sufficient, and can also ensure that the cohesiveness of the adhesive layer does not cause poor effect due to over-thick or over-thin thickness, thereby balancing suitable cohesiveness and good therapeutic effect.

In some embodiments of the utility model, the netting layer 2 comprises a nylon mesh, a polyester mesh, a pure cotton mesh, or a blended mesh.

The nylon is polyamide and is mainly used for synthetic fibers, the most outstanding advantage is that the wear resistance is higher than that of all other fibers, is 10 times higher than that of cotton and 20 times higher than that of wool, and the wear resistance can be greatly improved by slightly adding some polyamide fibers into the blended fabric; when the stretch is extended to 3-6%, the elastic recovery rate can reach 100%; can withstand ten thousand times of bending without breaking. In civil use, the fabric can be blended or spun into various medical supplies and knitwear.

The terylene is polyester fiber and has wide application as civil fabrics and industrial fabrics. As textile materials, the polyester staple fibers can be spun purely and are also suitable for blending with other fibers, and the antistatic flame-retardant fabric can be produced by interweaving flame-retardant polyester fibers and conductive fibers; the flame-retardant fiber and the high-performance fiber are blended and interwoven to produce the high-performance flame-retardant fabric; by blending the flame-retardant fibers with fibers such as cotton and viscose, the comfort of the protective clothing can be improved, and secondary burns can be reduced.

The pure cotton is made of cotton, the chemical fiber fabric is wear-resistant, wrinkle-resistant and stiff, but the comfort is far lower than that of the pure cotton, and adverse reactions such as skin allergy of a human body can be effectively relieved.

The blended fiber, such as polyester-cotton blended fiber, is made of 65-67% of polyester and 33-35% of cotton, and has the advantages of both polyester and cotton, good elasticity and wear resistance under dry and wet conditions, stable size, small shrinkage, and high stiffness, low wrinkle resistance, easy washing and quick drying.

In this embodiment, the mesh number of the gauze layer is 20-100 mesh, and the mesh number falling within this range has good permeability and adsorption capacity, and does not cause excessive overflow due to the colloid dose or the drug dose of the adhesive layer 3. Mesh is the number of holes per square inch. The larger the mesh number, the smaller the pore size, indicating finer particles can pass through. The gauze layer in this embodiment is preferably a nylon net widely used for medical products, and is not limited in other embodiments.

In some embodiments of the present invention, the side of the adhesive layer 3 away from the film layer 1 is provided with a protective film.

In this embodiment, the protective film covers the side having the tackiness and is used to seal the tacky adhesive layer 3 having the drug. The protective films themselves do not have tackiness and are bonded to each other by the tackiness of the adhesive layer 3. In application, the protective film is torn off and applied to affected part of skin. When not in use, the protective film is not required to be torn off and is stored in the bag or the packaging bag.

As shown in fig. 4, in some embodiments of the present invention, a bag 101 is disposed on a surface of the film layer 1 away from the gauze layer 2, and an alcohol wiper 1011 is disposed in the bag 101.

People can attach the plaster to the skin inevitably due to injury in daily life, but both the band-aid and the plaster have the defect that the skin can have residual offset printing of the plaster after being torn off after long-term use, and the plaster is very difficult to remove. The utility model solves the problem, in the embodiment, the alcohol wiping sheet 1011 is a commercially available product, and is a cotton sheet soaked with medical alcohol, and the alcohol wiping sheet 1011 is used for wiping the part to be cleaned, so that residual colloid can be effectively cleaned, skin redness caused by dry rubbing of the skin is avoided, and the damage to the skin is reduced.

In addition, before use, the alcohol swabs 1011 may be used to disinfect and wipe the red swollen and sore area to achieve better therapeutic effect.

In some embodiments of the present invention, film layer 1 is a stretchable film layer 1.

In actual production, the size of the patches of the same product is often consistent, which results in that when the area of the affected part of a user is large, a plurality of patches are often attached side by side or overlapped to achieve a treatment effect, and thus spreading waste is caused. In this embodiment, the film layer 1 has elasticity, and the user can stretch the edge of the film layer 1 to expand the fitting area to some extent, and then act on the affected part. The stretchable film layer 1 provides convenience to the user.

As shown in fig. 2, in some embodiments of the present invention, a heating portion is disposed on a side of the film layer 1 away from the gauze layer 2, the heating portion includes a raw material layer, a gelatin layer 4 and a non-woven bag 5, the raw material layer is disposed in the non-woven bag 5, and the gelatin layer 4 is disposed on both sides of the non-woven bag 5.

In this embodiment, the non-woven fabric bag 5 is made of a microporous air permeable membrane, and the non-woven fabric bag 5 is further provided with an air impermeable outer membrane, and when in use, the outer membrane is removed to expose the non-woven fabric bag 5 to air, and oxygen in the air enters the non-woven fabric bag through the air permeable membrane. The raw material layer is a polymer synthesized by iron powder, stone, activated carbon, inorganic salt, water and the like, and can generate exothermic reaction under the action of oxygen in the air. The non-woven cloth bag 5 is characterized by uniformity, no leakage and good air permeability. The gelatin layer 4 is preferably a pressure sensitive adhesive coating, which is firmly bonded. The non-woven cloth bag 5 is bonded with one surface of the film layer 1 far away from the gauze layer 2 through the gelatin layer 4.

Besides the therapeutic effect of the medicament, the heating part can relieve the pain of waist, shoulder, stomach, leg and joint, and can also eliminate the pain caused by aversion to cold, such as arthritis, scapulohumeral periarthritis, lumbago and skelalgia, rheumatism and rheumatoid diseases, cold limbs, and pain of affected part due to cold. The heating part is matched with a patch with plaster for use, which is beneficial to the opening of capillary vessels at the affected part and can ensure that the medicine can better enter the skin to be absorbed.

As shown in fig. 3, in some embodiments of the utility model, the side of the film layer 1 remote from the adhesive layer 3 is provided with a decorative layer 6.

Most of the patches in the prior art are not good in color, and when a user needs to use the patches for a long time, the user inevitably takes the patches and goes out, and the aesthetic degree of clothes of the user is influenced to a certain extent. The decorative layer 6 in this embodiment is a film with ornamental patterns, which covers and adheres to the surface of the film layer 1 shown outside, so that the beauty of the patch can be improved, and the interestingness of products in the field is increased.
