Description

Technical Field

[0001] The utility model relates to the technical field of acne stickers, in particular to a microneedle acne sticker. Background Technique

[0002] An acne sticker is used to attach to acne, and the medicine on the sticker is used to treat acne in the form of attachment or stimulation. At present, there are two main categories on the market. One is a flat patch. This type of patch relies on attaching to the surface layer of acne to let the acne mature naturally, and finally locks the acne solution to promote skin recovery. The other is a patch with microneedles. The surface of this type of patch is provided with soluble microneedles with attached medicine, and relies on the microneedles to insert into the epidermis of acne to achieve the purpose of rapid treatment. However, this type of microneedle patch also has a drawback, that is, when piercing the epidermis of acne, a large amount of acne solution flows out around, and it cannot well adsorb the acne solution relying on its own gauze base, and finally it is easy to contaminate the surrounding skin, resulting in more acne growing instead of treating one acne well. Another problem is that traditional microneedles mostly still use columnar base microneedles because this type of microneedle is easier to demold. However, the needle body base of this type of microneedle has limited bearing capacity, and the components of the soluble microneedles contain glue and hyaluronic acid. The glue is used for adhesion, and hyaluronic acid is beneficial to skin recovery. When the microneedle base is not firm, the proportion of glue in the production formula needs to be increased, thus compressing the proportion of hyaluronic acid. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a microneedle acne sticker to solve the technical problems mentioned in the background technique.

[0004] To solve the technical problems, the utility model is realized by adopting the following technical scheme:

[0005] A microneedle acne sticker, comprising: a hydrocolloid dressing base, which has strong water absorption and solubility and forms a flat base, and the hydrocolloid dressing base also has a sticky property to facilitate attachment to the edge of acne skin;

[0006] A soluble patch, which is attached to the upper end of the hydrocolloid dressing base and has a soluble property. At least one end of the soluble patch is provided with a liquid guide gap, and the distance from the innermost end of the liquid guide gap to the center point of the soluble patch is less than the distance from the innermost end of the non-gap area to the center point of the soluble patch;

[0007] Microneedles, which are integrally formed on the upper end of the soluble patch and have a soluble property.

[0008] Specifically, the microneedle is a pointed cone composed of an isosceles triangle with three sides.

[0009] Specifically, the height of the microneedle is 150 - 300 μm.

[0010] Specifically, the soluble patch includes a core inner region and an extended outer region, and a liquid guiding gap is formed by the gaps between multiple extended outer regions.

[0011] Specifically, it further includes a skin-adhering glue, which is distributed around the outer periphery of the hydrocolloid dressing substrate and is used to adhere to the skin around the acne to prevent the acne patch from falling off.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model uses a hydrocolloid dressing with stronger water absorption capacity as the substrate, and its absorption and dissolution capacity can reach the effect of swelling 12 times, which can adsorb more acne solutions. In addition, a liquid guiding gap is provided on the soluble patch, so that the acne solution flowing out after being punctured can be adsorbed and locked on the hydrocolloid dressing substrate faster, avoiding contamination of the adjacent skin. In addition, by setting the soluble patch into a core inner region and an extended outer region, the acne is punctured and adhered by relying on the core inner region, and the acne solution is sucked away through the liquid guiding gap. At the same time, the microneedles on the extended outer region are used to fit or shallowly pierce the normal skin to block part of the overflowing acne solution, preventing the adjacent skin from being infected, so as to achieve the purpose of local treatment and prevention of infection of a single acne. In addition, the microneedles in the present utility model patent adopt an isosceles triangular prism surface structure, and each surface is an isosceles triangle. Such a structure is more stable and not easy to bend when piercing the skin, so that the proportion of the glue component in the soluble microneedle formula can be reduced and the proportion of the hyaluronic acid component can be increased.

[0023] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0024] Reference Figures 1 to 8 :

[0025] The present utility model discloses a microneedle acne patch, which includes a hydrocolloid dressing base 10, a soluble patch 20 and microneedles 30. The hydrocolloid dressing base 10 has strong water absorption and solubility and forms a flat base. And preferably, plant extracts can be added to the hydrocolloid dressing of the present utility model to achieve an anti-inflammatory effect. The hydrocolloid dressing base 10 also has a sticky property to facilitate attachment to the edge of acne skin; this sticky property can be achieved in two ways. One is to add components with glue properties to the hydrocolloid dressing, so that the hydrocolloid dressing base 10 itself has stickiness. The other is to add a skin-adhering adhesive 101 to the outer periphery of the hydrocolloid dressing base 10 for attaching to the skin around the acne to prevent the acne patch from falling off. This layer of skin-adhering adhesive 101 can be isolated by an easy-to-tear film when not in use daily to prevent exposure to the air or adhesion by other substances;

[0026] Specifically, the soluble patch 20 is attached to the upper end of the hydrocolloid dressing base 10 and has a soluble property. The microneedles 30 are integrally formed on the upper end of the soluble patch 20 and have a soluble property. The solubility of the microneedles 30 can be quickly dissolved when they are inserted into acne skin and touch blood. The drug components carried by them are used to administer medicine to the acne. At least one end of the soluble patch 20 is provided with a liquid conduction gap 201. The distance from the innermost end of the liquid conduction gap 201 to the center point of the soluble patch 20 is less than the distance from the innermost end of the non-gap area to the center point of the soluble patch 20; here, as shown in the attached specification Figure 2As shown, where the distance A is less than the distance B. With such a setting, when the microneedles 30 in the central area pierce the outer epidermis of the pimple, the pimple solution (blood and water) will seep out quickly. In a traditional pimple patch, the pimple solution will seep out along with the soluble patch 20 until it reaches the outermost gauze base layer and is absorbed by the gauze. In this way, the seepage speed will be slowed down, and when it seeps out, the entire soluble patch 20 will be contaminated before reaching the outermost layer. However, in the present utility model, a liquid guiding gap 201 is provided. After being pierced, the seeping pimple solution will first enter the liquid guiding gap 201. Below the liquid guiding gap 201 is the hydrocolloid dressing base 10, which can immediately adsorb the pimple solution and expand outward, and can suck away the continuously seeping pimple solution. In this way, the situation where the entire soluble patch 20 is contaminated is reduced, and at the same time, the adsorption rate of the pimple solution is increased, thereby reducing the seepage of the pimple solution to healthy skin and preventing the growth of more healthy skin, achieving the purpose of local treatment and preventing infection.

[0027] Specifically, compared with the traditional microneedles 30 using a cylinder as the base, here, the microneedles 30 are pyramids composed of three-sided isosceles triangles, thus forming microneedles 30 with an isosceles triangular prism structure. The microneedles 30 with such a structure are more stable and more solid when piercing into pimply skin. The triangular structure is more stable. In this way, the proportion of glue and hyaluronic acid in the formula can be adjusted. Increasing the proportion of hyaluronic acid can help the subsequent skin recover faster.

[0028] Preferably, the height of the microneedles 30 is 150 - 300 μm. In this way, when the soluble microneedles 30 pierce the skin, they can at most reach the dermis layer and will not continue to penetrate to avoid damaging the skin structure.

[0029] Specifically, in a certain situation, if the periphery of the skin at the core of a pimple is infected with pimple solution, it is also prone to infection and the growth of new pimples. The traditional pimple patches can only solve this problem by increasing the area of the pimple patch. However, increasing the area of the pimple patch will, on the one hand, increase the cost of the patch, and on the other hand, a large-area pimple patch applied to the skin will cause discomfort or affect the facial beauty. A solution is proposed in this utility model patent, specifically: The soluble patch 20 includes a core inner area 21 and an extended outer area 22. The gaps between multiple extended outer areas 22 form a liquid guiding gap 201. Specifically, the core inner area 21 has a size that just fits the size of a regular pimple, and the extended outer area 22 extends further outward on the outside of the core inner area 21, and its shape can also be designed into shapes such as a heart shape, a five-pointed star, a four-leaf clover, a triangle, etc. according to the preferences of different consumers. The core inner area 21 is used to attach to and puncture the pimple for drug administration. The soluble microneedles 30 will quickly dissolve inside the pimple after puncturing the pimple, and then treat the pimple through the drug components inside. However, some of the pimple solution that flows out will also contaminate the healthy skin beside. At this time, the microneedles 30 in the extended outer area 22 come in handy. They can be attached to the outside of the healthy skin. Because the texture of the healthy skin is relatively hard and it is difficult to puncture, they stay on the surface layer. When there is leaking pimple solution that touches the microneedles 30, the microneedles 30 will quickly dissolve and release the drug components inside, thereby secondarily blocking the infection of the leaking pimple solution to the healthy skin. The mixture of the dissolved microneedles 30 and the pimple solution will subsequently be slowly absorbed by the hydrocolloid dressing base 10 on the outside, and the pimple blood and water that seeps through the liquid guiding gap 201 area will just be absorbed by the hydrocolloid dressing at the lower end, so that the whole pimple patch remains dry.

[0030] The above embodiments are only the preferred embodiments of the present utility model and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
