Description

Technical Field

[0001] The utility model belongs to the technical field of eye patches and relates to a microneedle eye patch. Background Art

[0002] The microneedle patch product is provided with a soluble microneedle array carrying effective ingredients such as drugs, and is a transdermal drug delivery patch product. When the microneedle patch product is used, it is pressed on the human skin by hand or a microneedle injector, so that the soluble microneedle array of the microneedle patch product penetrates the skin, and micron-level drug delivery channels are formed safely and painlessly in the skin. The effective ingredients such as drugs carried by the soluble microneedle array are dissolved and released deep in the skin, enhancing the permeability of the skin to macromolecular active ingredients and drugs, with high absorption efficiency, safety and painlessness, and realizing transdermal drug delivery.

[0003] In actual use, in general eye patches, the hyaluronic acid microneedle sheet is directly partially exposed to the air, and the hyaluronic acid microneedle sheet needs to rely on an auxiliary hydrogel patch to provide moisture to dissolve the hyaluronic acid microneedle sheet in the microneedle eye patch. For example, Chinese Patent Application [Authorized Publication No. CN219050094U] discloses a microneedle eye patch, a sticky patch, the adhesion surface of the sticky patch can adhere to the skin surface, and a first microneedle array and a second microneedle array are arranged on the adhesion surface of the sticky patch. The first microneedle array can be used to cover the Chengqi acupoint and Sibai acupoint of the human eye, and the second microneedle array can be used to cover the Tongziliao acupoint of the human eye. The first microneedle array is formed by arranging a plurality of soluble microneedles, and the second microneedle array is formed by arranging a plurality of soluble microneedles. The adhesion surface of the sticky patch can adhere to one end surface of the support sheet. The support sheet is provided with a first accommodation hole and a second accommodation hole penetrating through it. The soluble microneedles of the first microneedle array penetrate through the first accommodation hole, and the soluble microneedles of the second microneedle array penetrate through the second accommodation hole.

[0004] The above structure is provided with a first microneedle array and a second microneedle array on the adhesion surface of the sticky patch, and a first accommodation hole and a second accommodation hole are penetrated through the support sheet. When in use, the support sheet needs to be peeled off. Since the sticky patch is adhered to the support sheet, when the support sheet is peeled off, because the soluble microneedles of the first microneedle array and the second microneedle array are involved, and the support sheet is a one-piece structure with only a plurality of dividing gaps provided, it is easy to touch the first microneedle array and the second microneedle array when the entire support sheet is peeled off, which is likely to affect the sticking effect of the microneedle eye patch. Summary of the Utility Model

[0005] The purpose of the present utility model is to propose a microneedle eye patch in view of the above problems existing in the prior art. The technical problem to be solved by the present utility model is: how to solve the problem that the soluble microneedles on the microneedle eye patch are easily damaged when the support sheet is peeled off in the existing microneedle eye patch.

[0006] The object of the utility model can be achieved by the following technical solutions:

[0007] A micro-needle eye patch, comprising an arc-shaped back film, a micro-needle patch with soluble micro-needles is pasted in the middle of the back film, characterized in that two arc-shaped release paper layers are pasted on the outer edge of the back film, the two ends of one release paper layer are close to the two ends of the other release paper layer and are combined to form a limiting ring, the micro-needle patch is located within the limiting ring, a splitting gap is formed at one end where the two release paper layers are close to each other, and there is always a clearance gap between the side wall of the release paper layer close to the micro-needle patch and the micro-needle patch.

[0008] Working principle: When the micro-needle eye patch needs to be used, the two release paper layers can be first peeled off from the back film. The entire micro-needle patch is located within the limiting ring. Therefore, with the arrangement of the two release paper layers, the micro-needle patch will not be affected when the release paper layers are peeled off. One end where the two release paper layers are close to each other has a splitting gap, and there is always a clearance gap between the side wall of the release paper layer close to the micro-needle patch and the micro-needle patch. The back glue and the release paper layer are relatively soft, so the release paper layer can be quickly lifted from the splitting gap, and then the release paper layer can be peeled off. Moreover, the setting of the clearance gap enables a clearance gap to exist between the release paper layer and the micro-needle patch during fitting and peeling, preventing the release paper layer from accidentally touching the micro-needle patch when being peeled off, improving the stability of the use of the micro-needle patch and achieving the rapid pasting of the micro-needle eye patch. At this time, a part of the sticky pasting part of the back film is exposed. Then, the side with the micro-needle patch is aligned with the eye circumference and the back film is attached to the facial skin. Since the periphery of the back film is the pasting part, a sealed space is formed after pasting. The soluble micro-needles of the micro-needle patch are in the sealed space, and the human body will evaporate part of the moisture and condense it in the sealed space, thus providing moisture for the dissolution of the soluble micro-needles, so that the soluble micro-needles do not need external moisture to achieve dissolution. The settings of the two release paper layers, the splitting gap and the clearance gap enable the release paper layer to be safely peeled off when being peeled off, and do not affect the soluble micro-needles of the micro-needle patch, improving the stability of the use of the micro-needle eye patch.

[0009] In the above-mentioned micro-needle eye patch, the splitting gap is located at the left and right ends of the micro-needle patch.

[0010] The position setting of the splitting gap enables the release paper layer to be peeled off from the left and right ends of the micro-needle patch, facilitating the rapid peeling of the release paper layer and improving the convenience of use of the micro-needle eye patch.

[0011] The two splitting gaps are on the same horizontal line, making it more convenient to cut the splitting gap during production and further reducing the production cost of the micro-needle eye patch.

[0012] In the above-mentioned microneedle eye patch, the left and right ends of the microneedle patch are bent forward, one of the release paper layers includes a bonding portion located above the microneedle patch, and the left and right ends of the bonding portion are bent downward to form a separation portion, and the other release paper layer includes a surrounding portion located below the microneedle patch, and the left and right ends of the surrounding portion are bent upward to form a limiting portion, and the above-mentioned separation gap is formed between the separation portion and the limiting portion located at the same end.

[0013] Through the setting of the separation part and the limiting part, the wrapping and bonding of the left and right ends of the microneedle patch is achieved. Through the setting of the separation part and the limiting part, the separation gap is located in the middle of the left and right ends of the microneedle patch. On the one hand, it avoids the separation part or the limiting part from tilting up when placed, and on the other hand, the back adhesive sheet is covered as much as possible to maintain the bonding adhesion of the back adhesive sheet, thereby improving the stability of the microneedle eye patch and avoiding damage when not in use.

[0014] In the above-mentioned microneedle eye patch, the separation gap is 1 mm to 2 mm.

[0015] By setting the value range of the separation gap, the distance between the two release paper layers is made larger, which is convenient for users to peel off.

[0016] In the above-mentioned microneedle patch, the width of the release paper layer is equal at all locations.

[0017] The setting of this structure ensures that the adhesive width of the backing sheet outside the microneedle eye patch is equal, ensures the stability of the entire outer edge of the microneedle eye patch when it is pasted around the eye, and ensures the sealing effect, so that the water evaporated from the human body can better dissolve the soluble microneedles, thereby improving the stability of use.

[0018] Compared with the prior art, the present microneedle eye patch has the following advantages: the back adhesive sheet is surrounded by adhesive parts, which form a closed space after pasting; the soluble microneedles of the microneedle patch are in the closed space; the human body will evaporate part of the water and condense it in the closed space, thereby providing moisture for the soluble microneedles to dissolve, so that the soluble microneedles do not need to use external moisture to dissolve; the setting of two release paper layers, dividing gap and giving way gap allows the release paper layer to be safely peeled off without affecting the soluble microneedles of the microneedle patch, thereby improving the stability of the microneedle eye patch.

[0021] In the figure, 1 is the back film; 2 is the microneedle patch; 3 is the release paper layer; 31 is the bonding part; 32 is the separation part; 33 is the surrounding part; 34 is the limiting part; 4 is the limiting ring; 5 is the separation gap; 6 is the clearance gap; 7 is the dividing gap. Detailed implementation manners

[0022] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0023] As Figure 1 shown, this microneedle eye patch includes an arc-shaped back film 1, and a microneedle patch 2 with soluble microneedles is pasted in the middle of the back film 1.

[0024] Specifically, as Figure 1 and Figure 2 shown, two arc-shaped release paper layers 3 are pasted on the outer edge of the back film 1. The two ends of one release paper layer 3 are close to the two ends of the other release paper layer 3 and are combined to form a limiting ring 4. The microneedle patch 2 is located inside the limiting ring 4. A dividing gap 7 is formed between the ends of the two release paper layers 3 that are close to each other.

[0025] Working principle: When the microneedle eye patch needs to be used, the two release paper layers 3 can be first peeled off from the back film 1. The microneedle patch 2 is entirely located inside the limiting ring 4. Therefore, with the setting of the two release paper layers 3, the peeling of the release paper layer 3 will not affect the microneedle patch 2. And the ends of the two release paper layers 3 that are close to each other have a dividing gap 7. The back glue and the release paper layer 3 are relatively soft, and the release paper layer 3 can be quickly lifted from the dividing gap 7, and then the release paper layer 3 is peeled off, realizing the quick pasting of the microneedle eye patch. At this time, a part of the sticky pasting part of the back film 1 is exposed. Then, the side with the microneedle patch 2 is facing the eye area and the back film 1 is pasted on the facial skin. Since the four sides of the back film 1 are all pasting parts, a closed space is formed after pasting. The soluble microneedles of the microneedle patch 2 are in the closed space. The human body will evaporate part of the moisture and condense it in the closed space, thus providing the moisture for dissolving the soluble microneedles. Therefore, the soluble microneedles do not need to use external moisture to achieve dissolution. The setting of the two release paper layers 3 and the dividing gap 7 enables the safe peeling of the release paper layer 3 during peeling and does not affect the soluble microneedles of the microneedle patch 2, improving the stability of the use of the microneedle eye patch.

[0026] As Figure 1 and Figure 2As shown, there is always a clearance gap 6 between the side wall of the release paper layer 3 close to the microneedle patch 2 and the microneedle patch 2. The splitting gaps 7 are located at the left and right ends of the microneedle patch 2, and the two splitting gaps 7 are on the same horizontal line, making it more convenient to cut the splitting gaps 7 during production and further reducing the production cost of the microneedle patch.

[0027] As Figure 1 and Figure 2 shown, the left and right ends of the microneedle patch 2 are bent forward. One release paper layer 3 includes a fitting portion 31 located in front of the microneedle patch 2, and the left and right ends of the fitting portion 31 are bent backward to form a separating portion 32. The other release paper layer 3 includes an enclosing portion 33 located behind the microneedle patch 2, and the left and right ends of the enclosing portion 33 are bent forward to form a limiting portion 34. The above-mentioned splitting gap 7 is formed between the separating portion 32 and the limiting portion 34 at the same end.

[0028] As Figure 1 shown, the splitting gaps 7 are all 1 mm to 2 mm.

[0029] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
