Description

Technical Field

[0001] The invention relates to the technical field of medical patch application, in particular to an acne-removing patch with soluble needle-shaped crystals. Background Art

[0002] Acne, also known as acne, is a common skin problem that often brings many adverse effects to people. First of all, acne will form redness, swelling, pustules, etc. on the skin, affecting the appearance of the face or other parts, which will greatly affect a person's self-confidence and self-image, especially for adolescents in puberty. Therefore, if acne is not handled properly, such as squeezing it with your hands, it may not only cause bacterial infection and leave scars, but also may cause psychological problems such as anxiety and depression, especially when the acne problem persists or recurs.

[0003] Therefore, acne patches specifically used to treat acne have been very popular in recent years. With the advancement of technology, a variety of acne patches have emerged one after another. Among them, the products with higher market acceptance are acne patches with soluble needle-shaped crystals. For example, the Chinese utility model patent with application number "202320238005.2" and named "Gauze Microcrystal Acne Patch" discloses an acne patch, including a breathable gauze sheet and a soluble microneedle patch. The soluble microneedle patch is bonded to the breathable gauze sheet. The area of ​​the breathable gauze sheet is larger than that of the soluble microneedle patch. The soluble microneedle patch includes a substrate and microneedles. A plurality of microneedles are provided and arranged in an array on one side of the substrate, and the microneedles are arranged with their backs facing the breathable gauze sheet. The principle is that after the microneedles penetrate the skin, the entire soluble microneedle patch will dissolve into liquid or colloidal state, and the material components used to repair and treat acne inside the soluble microneedle patch will enter the skin through the holes pierced by the microneedles. Compared with common gauze microcrystal acne patches, it is more conducive to the absorption and utilization of the material components used to repair and treat acne, and the effect of treating and repairing acne is better.

[0004] Such acne patches can indeed improve the treatment effect of acne. However, after the microneedles pierce the skin, the microneedles containing therapeutic substances will gradually dissolve in the pus around the puncture. It is also this part of the pus that will slowly seep out first and be absorbed by the breathable gauze. This causes the therapeutic substances in the microneedles to be in a state of loss and cannot be retained deeply in acne to play a role, affecting the efficacy. Summary of the invention

[0005] In view of the defects of the prior art, the technical problem to be solved by the present invention is to provide an acne patch with soluble needle-shaped crystals, so as to avoid the soluble needle-shaped crystals with therapeutic substances dissolving only in the pus around the skin puncture, so that the soluble needle-shaped crystals can be retained deeply in the acne and improve the efficacy.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An acne-removing patch with soluble needle-like crystals comprises an applicator and a microneedle sheet, wherein the microneedle sheet is arranged in the middle of the application side of the applicator, the soluble needle-like crystals are arranged on the microneedle sheet, the outer area of ​​the microneedle sheet on the applicator has an adhesive area, and further comprises a connecting portion and a pressing capsule, wherein the connecting portion is arranged in the middle of the applicator, a through hole is arranged in the center of the connecting portion, the pressing capsule is a hollow elastic soft capsule body with an air outlet, the air outlets of the microneedle sheet and the pressing capsule are respectively installed at both ends of the through hole, when the applicator is applied, the end face of the through hole is in contact with the skin, the through hole and the inner cavity of the pressing capsule form a closed cavity, and the microneedle sheet adopts a breathable and water-absorbing material.

[0008] When in use, the patient squeezes the pressing capsule to expel part of the air in the pressing capsule, and at the same time, sticks the patch to the affected area, and makes the microneedle sheet just located at the acne. At this time, the soluble needle-shaped crystals puncture the skin at the acne. After the application is completed, the user releases the pressing capsule, and the pressing capsule restores its shape under the action of elasticity. Since the end face of the through hole of the patch is in contact with the skin, the through hole and the inner cavity of the pressing capsule form a closed cavity, and a suction force is formed on the puncture. This suction force can accelerate the outflow of pus from the puncture, and the outflowing pus is absorbed by the microneedle sheet, while the soluble needle-shaped crystals will not be completely dissolved in this short period of time. After a large amount of pus flows out, it can still be partially retained in the acne, playing a role in deep treatment.

[0009] Preferably, the patch is in the shape of an elongated strip, the adhesive areas are arranged at both ends of the patch, the microneedle sheet is arranged between the adhesive areas, the pressing capsule extends from the through hole to one end of the patch and is in the shape of an elongated strip, and the pressing capsule is closely connected to the patch.

[0010] Usually, technicians tend to think of setting the pressing capsule directly above the microneedle sheet, but such a solution mainly has the following problems: First, if you want to ensure that a large suction force is formed on the puncture, you need to design a large pressing capsule. Installing such a pressing capsule on the patch will cause the patch to be subjected to a large force and affect the firmness of the patch. It also causes the shape of the acne patch to be more strange, affecting the user's experience. What is more disadvantageous is that if the pressing capsule is directly set above the microneedle sheet, when the user presses the pressing capsule, it is very likely that the entire acne patch (including the microneedle sheet) will be greatly deformed, and it is difficult to complete the firm application of the acne patch. Therefore, this solution designs the patch and the pressing capsule into a long strip shape, which effectively shortens the height of the pressing capsule, and at the same time makes the pressing point staggered with the position of the microneedle sheet. When the user presses the pressing capsule, the pressing capsule can be deformed, and one end of the patch can be pressed against the skin at the same time. Then, the other end of the patch can be attached to the skin to complete the application, which effectively solves the above problems.

[0011] Furthermore, the pressing capsule is in a flat strip shape, and the side of the pressing capsule away from the patch is a pressing surface, and a connecting rib is provided on the pressing surface, and the connecting rib extends along the length direction of the pressing capsule. After the connecting rib is provided, when the user presses a certain position of the pressing capsule, the connecting rib will cause other positions of the pressing capsule to deform, thereby expanding the deformation range and improving the suction force on the puncture hole.

[0012] Preferably, the connecting rib is arranged inside the pressing surface of the pressing capsule. Such a design avoids the problem that the connecting rib affects the pressing feel of the user.

[0013] Furthermore, the connection part protrudes upward from the surface of the patch facing away from the application side to form a connection protrusion, and a connection hole is provided on the side of the pressing capsule that abuts against the patch, and the connection protrusion is inserted into the connection hole. Since it is necessary to ensure that the connection part and the pressing capsule are reliably sealed, if the connection part does not protrude from the patch, the pressing capsule can only be connected to the patch in a butt-jointed manner, and the sealing reliability is poor. The above structure can avoid this problem.

[0014] At the same time, a circle of concave stoppers is provided at one end of the through hole close to the application side of the patch, and a circle of convex stoppers is provided at one end of the microneedle sheet away from the soluble needle-like crystals, and the convex stoppers are embedded in the concave stoppers. The setting of the stoppers can ensure the installation accuracy of the microneedle sheet and the piercing effect of the soluble needle-like crystals on the skin.

[0015] In addition, a circle of soft skirt is provided on the application side of the patch, and the soft skirt is arranged around the through hole and extends outward from the patch. The setting of the soft skirt can further improve the air tightness of the closed cavity formed by the through hole and the inner cavity of the pressing bag after the patch is applied, and further improve the pus suction effect.

[0016] Preferably, the cross-sectional area of ​​the through hole near one end of the microneedle sheet does not exceed one-half of the end surface area of ​​the microneedle sheet, and the cross-sectional area of ​​the through hole becomes smaller as it moves away from the microneedle sheet, forming a tapered hole. Since the acne patch may need to deal with acne of different sizes, the microneedle sheet is often designed to be larger, which results in a larger internal space of the through hole, which is not conducive to improving the suction force. Therefore, this solution minimizes the internal space of the through hole while ensuring that the through hole corresponds to the microneedle sheet.

[0017] Furthermore, the length of the soluble needle-like crystals at the microneedle sheet corresponding to the through hole near one end of the microneedle sheet is longer than the length of the soluble needle-like crystals at other positions on the microneedle sheet. The advantage of this is that the longer soluble needle-like crystals ensure that the puncture openings are concentrated as much as possible at the corresponding position of the through hole, so that more pus can be sucked out through the suction force formed by the through hole, further improving the pus suction effect.

[0018] In summary, such an acne patch with soluble needle-shaped crystals avoids the soluble needle-shaped crystals with therapeutic substances from dissolving only in the pus around the skin puncture, and allows them to be retained deep in the acne, thereby improving the efficacy.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] An anti-acne patch with soluble needle-shaped crystals, such as Figure 1 As shown in the cross-sectional view, it includes an application piece 1 and a microneedle sheet 2, the microneedle sheet 2 is arranged in the middle of the application side of the application piece 1, the microneedle sheet 2 is provided with soluble needle crystals 21, and the outer area of ​​the microneedle sheet 2 on the application piece 1 has an adhesive area 11, as shown in FIG. Figure 1 , Figure 5 as well as Figure 6As shown, it also includes a connecting part 3 and a pressing capsule 4. The connecting part 3 is arranged in the middle of the patch 1. A through hole 31 is arranged in the center of the connecting part 3. The pressing capsule 4 is a hollow elastic soft capsule with an air outlet 41. The microneedle sheet 2 and the air outlet 41 of the pressing capsule 4 are respectively installed at both ends of the through hole 31. When the patch 1 is applied, the end face of the through hole 31 is in contact with the skin, and the through hole 31 and the inner cavity of the pressing capsule 4 form a closed cavity. The microneedle sheet 2 is made of breathable and water-absorbent material.

[0029] When in use, the patient squeezes the pressing capsule 4 to expel part of the air in the pressing capsule 4, and at the same time, the patch 1 is attached to the affected area, and the microneedle sheet 2 is located exactly at the acne. At this time, the soluble needle-shaped crystals 21 puncture the skin at the acne. After the application is completed, the user releases the pressing capsule 4, and the pressing capsule 4 restores its shape under the action of elasticity. Since the end face of the through hole 31 is attached to the skin when the patch 1 is applied, the through hole 31 and the inner cavity of the pressing capsule 4 form a closed cavity, and a suction force will be formed on the puncture. This suction force can accelerate the pus to flow out of the puncture, and the pus is absorbed by the microneedle sheet 2, while the soluble needle-shaped crystals 21 will not be completely dissolved in this short time. After a large amount of pus flows out, it can still be partially retained in the acne, playing a role in deep treatment.

[0030] Preferably, Figure 1 As shown in the cross-sectional view, the patch 1 is in the shape of an elongated strip, the adhesive areas 11 are arranged at both ends of the patch 1, the microneedle sheet 2 is arranged between the adhesive areas 11, the pressing capsule 4 extends from the through hole to one end of the patch 1 and is in the shape of an elongated strip, and the pressing capsule 4 is closely connected to the patch 1.

[0031] Usually, technicians tend to think of setting the pressing capsule 4 directly above the microneedle sheet 2, but such a solution mainly has the following problems: First, if you want to ensure that a large suction force is formed on the puncture hole, you need to design a large pressing capsule 4. Installing such a pressing capsule 4 on the patch 1 will cause the patch 1 to be subjected to a large force and affect the firmness of the patch. It also causes the shape of the acne patch to be more strange, affecting the user's experience. What is more disadvantageous is that if the pressing capsule 4 is directly set above the microneedle sheet 2, when the user presses the pressing capsule 4, it is very likely that the entire acne patch (including the microneedle sheet 2) will be greatly deformed, making it difficult to complete the firm application of the acne patch. Therefore, in this solution, both the patch 1 and the pressing capsule 4 are designed to be long strips, which effectively shortens the height of the pressing capsule 4 and staggers the pressing point with the position of the microneedle sheet 2. When the user presses the pressing capsule 4, the pressing capsule 4 can be deformed and one end of the patch 1 can be pressed against the skin. The other end of the patch 1 can then be attached to the skin to complete the application, which effectively solves the above-mentioned problem.

[0032] Further, such as Figure 1 as well as Figure 3As shown in the cross-sectional view of , the pressing capsule 4 is in a flat long strip shape, and the side of the pressing capsule 4 away from the patch 1 is a pressing surface 42, and a connecting rib 43 is provided on the pressing surface 42, and the connecting rib 43 extends along the length direction of the pressing capsule 4. After the connecting rib 43 is provided, when the user presses a certain position of the pressing capsule 4, the connecting rib 43 will cause other positions of the pressing capsule 4 to deform, which plays a role in expanding the deformation range and improving the suction force on the puncture hole.

[0033] Preferably, the connecting rib 43 is arranged inside the pressing surface 42 of the pressing capsule 4. Such a design avoids the problem that the connecting rib 43 affects the pressing feel of the user.

[0034] Further, such as Figure 3 As shown in the cross-sectional view, the connecting portion 3 protrudes upward from the surface of the patch 1 facing away from the patch to form a connecting protrusion 32, and the pressing capsule 4 is provided with a connecting hole 44 on the side that abuts against the patch 1, and the connecting protrusion 32 is inserted into the connecting hole 44. Since it is necessary to ensure that the connecting portion 3 and the pressing capsule 4 are reliably sealed, if the connecting portion 3 does not protrude from the patch 1, the pressing capsule 4 can only be connected to the patch 1 in a butt-joined manner, and the sealing reliability is poor. The above structure can avoid this problem.

[0035] At the same time, if Figure 1 As shown in the cross-sectional view, a circle of concave stoppers 33 is provided at one end of the through hole 31 close to the application side of the patch 1, and a circle of convex stoppers 22 is provided at one end of the microneedle sheet 2 away from the soluble needle-like crystals 21, and the convex stoppers 22 are embedded in the concave stoppers 33. The setting of the stoppers can ensure the installation accuracy of the microneedle sheet 2 and the piercing effect of the soluble needle-like crystals 21 on the skin.

[0036] In addition, a circle of soft skirt 12 is also provided on the application side of the patch 1, and the soft skirt 12 is arranged around the through hole 31, and the soft skirt 12 extends outward from the patch 1. The provision of the soft skirt 12 can further improve the air tightness of the closed cavity formed by the through hole 31 and the inner cavity of the pressing bag 4 after the patch 1 is applied, and further improve the pus suction effect.

[0037] Preferably, Figure 3 As shown in the cross-sectional view, the cross-sectional area of ​​the through hole 31 near the end of the microneedle sheet 2 does not exceed one-half of the end surface area of ​​the microneedle sheet 2, and the cross-sectional area of ​​the through hole becomes smaller as it moves away from the microneedle sheet 2, thereby forming a tapered hole. Since the acne patch may need to deal with acne of different sizes, the microneedle sheet 2 is often designed to be larger, which results in a larger internal space of the through hole, which is not conducive to the improvement of suction. Therefore, this solution minimizes the internal space of the through hole while ensuring that the through hole corresponds to the microneedle sheet 2.

[0038] Further, such as Figure 3As shown in the cross-sectional view, the length of the soluble needle-shaped crystal 21 at the microneedle sheet 2 corresponding to the through hole 31 near one end of the microneedle sheet 2 is longer than the length of the soluble needle-shaped crystal 21 at other positions on the microneedle sheet 2. The advantage of this is that the longer soluble needle-shaped crystal 21 ensures that the puncture opening is concentrated as much as possible at the corresponding position of the through hole 31, so that more pus can be sucked out through the suction force formed by the through hole 31, further improving the suction effect of pus.

[0039] In summary, such an acne patch with soluble needle-shaped crystals avoids the soluble needle-shaped crystals with therapeutic substances from dissolving only in the pus around the skin puncture, and allows them to be retained deep in the acne, thereby improving the efficacy.

[0040] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
