Description

Technical Field

[0001] The present application relates to the technical field of soluble microneedles, and in particular to a bandage-type soluble microneedle product. Background Art

[0002] Soluble microneedles are also called microcrystal technology. Soluble microneedle technology is widely used in the medical and beauty skin care industries. Soluble microneedles are mainly made of water-soluble polymers. Drugs or other functional ingredients are generally distributed in the needle tip matrix. After piercing the skin, the needle tip absorbs a small amount of tissue fluid to dissolve and release drugs or other functional ingredients.

[0003] For example, Chinese patent application number 202010811553.0 discloses a soluble microneedle patch comprising: a sheet-like substrate and soluble polymer microneedles formed on the sheet-like substrate; for another example, Chinese patent application number 202010367191.0 discloses a soluble microneedle patch comprising a patch and a soluble needle body arranged on the front of the patch.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] After the soluble microneedle patch is attached to the skin, it is difficult for the soluble microneedle patch to fix itself, so the user needs to press the soluble microneedle patch with the fingertips for a long time. However, since the soluble microneedles are easy to dissolve, the higher temperature brought by the fingertips will accelerate the dissolution rate of the soluble microneedle patch, causing more ingredients to not have time to enter the skin and be absorbed. It may also cause safety hazards due to problems such as unclean fingertips, so it needs to be improved. Utility Model Content

[0006] The present application provides a bandage-type soluble microneedle product to improve the following technical problems:

[0007] After the soluble microneedle patch is attached to the skin, it is difficult for the soluble microneedle patch to fix itself, so the user needs to press the soluble microneedle patch with the fingertips for a long time. However, since the soluble microneedles are easy to dissolve, the higher temperature brought by the fingertips will accelerate the dissolution rate of the soluble microneedle patch, causing more ingredients to not have time to enter the skin and be absorbed. It may also cause safety hazards due to problems such as unclean fingertips.

[0008] The present application provides a bandage-type soluble microneedle product, which adopts the following technical solution:

[0009] A strap-type soluble microneedle product includes a soluble microneedle patch and a pressing strap. The soluble microneedle patch and the pressing strap are of a split structure, or the soluble microneedle patch is relatively fixed to the pressing strap. The pressing strap is used to be directly or indirectly fixed to the human body to apply a force for piercing the skin to the soluble microneedle patch.

[0010] In an implementable technical solution of the present application, one piece of the soluble microneedle patch is fixed to one pressing strap. The soluble microneedle patch is in a long strip shape and is arranged along the length direction of the pressing strap.

[0011] In an implementable technical solution of the present application, multiple bearing hard boards are spaced and fixed to one pressing strap. There are multiple pieces of the soluble microneedle patch, and the soluble microneedle patches are arranged in one-to-one correspondence with the bearing hard boards.

[0012] In an implementable technical solution of the present application, the widths of the bearing hard board and the soluble microneedle patch are greater than or equal to the width of the pressing strap.

[0013] In an implementable technical solution of the present application, an adhesive layer is provided between the bearing hard board and the soluble microneedle patch.

[0014] In an implementable technical solution of the present application, a medical layer with a drug component is provided between the adhesive layer and the bearing hard board.

[0015] In an implementable technical solution of the present application, a first fixing member is provided at one end of the pressing strap, and a second fixing member is provided at the other end of the pressing strap. The first fixing member and the second fixing member are detachably assembled.

[0016] In an implementable technical solution of the present application, the first fixing member and the second fixing member are respectively the fuzzy surface and the prickly surface of a magic tape, or the first fixing member and the second fixing member are respectively the male button and the female button of a press button.

[0017] In an implementable technical solution of the present application, the pressing strap is an elastic structure that can be elongated and shortened.

[0018] In an implementable technical solution of the present application, the pressing strap includes multiple elastic telescopic segments and multiple fixed-length segments. The elastic telescopic segments are connected between two adjacent fixed-length segments, and the soluble microneedle patch is relatively fixed to the fixed-length segments.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] When the pressure - applying bandage is directly or indirectly fixed to the human body, the binding force of the pressure - applying bandage can apply a force to the soluble microneedle patch to pierce into the skin, thus replacing the operation of fingertip - pressing the soluble microneedle patch. Furthermore, it will not accelerate the dissolution rate of the soluble microneedle patch due to the relatively high body temperature, and it is not easy to cause a situation where more components do not have time to enter the skin and be absorbed. It can also effectively avoid problems such as unclean fingertips, reducing potential safety hazards, and is the best choice when applying the soluble microneedle patch.

[0033] The following will further elaborate on the present application in conjunction with the Figures 1-5 drawings.

[0034] Embodiment 1

[0035] Embodiment 1 of the present application discloses a strap-type soluble microneedle product. Referring to Figure 1 , the strap-type soluble microneedle product includes a soluble microneedle patch 1 and a pressing strap 2. The soluble microneedle patch 1 and the pressing strap 2 are of a split structure. The pressing strap 2 is used to be directly or indirectly fixed on the human body to apply a force for piercing the skin to the soluble microneedle patch 1.

[0036] For example: The pressing strap 2 can be directly strapped around the waist or the arm, or can be buckled to the clothes, as long as it can apply pressure to the soluble microneedle patch 1.

[0037] The beneficial technical effects of the strap-type soluble microneedle product of Embodiment 1 of the present application are generally as follows:

[0038] When the pressure - applying band 2 is directly or indirectly fixed to the human body, the binding force of the pressure - applying band 2 can apply a force to the soluble microneedle patch 1 to pierce into the skin, thus replacing the operation of pressing the soluble microneedle patch 1 with a fingertip. Furthermore, it will not accelerate the dissolution rate of the soluble microneedle patch 1 due to the relatively high body temperature, and it is not easy to cause a situation where more components do not have time to enter the skin and be absorbed. It can also effectively avoid problems such as unclean fingertips, reducing potential safety hazards, and is the best choice when applying the soluble microneedle patch 1.

[0039] In this embodiment, the pressure - applying band 2 is a non - elastic structure with an unchangeable length. Specifically, the pressure - applying band 2 is a non - elastic non - woven strip, so that the pressure - applying band 2 has a certain air - permeability effect.

[0040] In this embodiment, one pressure - applying band 2 is fixed with one soluble microneedle patch 1. The soluble microneedle patch 1 is in a long - strip shape and is arranged along the length direction of the pressure - applying band 2, and the width of the pressure - applying band 2 is greater than the width of the soluble microneedle patch 1.

[0041] One end of the pressure - applying band 2 is provided with a first fixing member 6, and the other end of the pressure - applying band 2 is provided with a second fixing member 7. The first fixing member 6 and the second fixing member 7 are detachably assembled.

[0042] In this embodiment, the first fixing member 6 and the second fixing member 7 are respectively the fuzzy surface and the hook surface of Velcro.

[0043] Embodiment Two

[0044] The second embodiment of the present application discloses a band - type soluble microneedle product. Referring to Figure 2 , the difference from Embodiment One is as follows:

[0045] The soluble microneedle patch 1 is bonded to the side surface of the pressure - applying band 2 to form an integral structure, and the length of the soluble microneedle patch 1 is shorter than the length of the pressure - applying band 2.

[0046] Moreover, the pressure - applying band 2 is an elastic structure that can be elongated and shortened. Specifically, the pressure - applying band 2 is an elastic elastic band with a width of about 3 cm. After the pressure - applying band 2 is tied to the human body, due to the tightness of the pressure - applying band 2, a relatively large pressure is generated to press the soluble microneedle patch 1.

[0047] Embodiment Three

[0048] The third embodiment of the present application discloses a band - type soluble microneedle product. Referring to Figure 3 and Figure 4 , the difference from Embodiment One is as follows:

[0049] A plurality of load-bearing hard plates 3 are fixedly arranged at intervals on a pressure-applying strap 2. There are multiple soluble microneedle patches 1, and the soluble microneedle patches 1 and the load-bearing hard plates 3 are arranged in one-to-one correspondence. The fixing method of the load-bearing hard plate 3 can be selected as: adhesive fixation or snap connection.

[0050] Moreover, the widths of the load-bearing hard plate 3 and the soluble microneedle patch 1 are greater than the width of the pressure-applying strap 2. In other embodiments, the widths of the load-bearing hard plate 3 and the soluble microneedle patch 1 can also be equal to the width of the pressure-applying strap 2.

[0051] The material of the load-bearing hard plate 3 is preferably a plastic plate or a cardboard, or other composite plates.

[0052] In order to improve the connection firmness between the soluble microneedle patch 1 and the load-bearing hard plate 3, an adhesive layer 4 is provided between the load-bearing hard plate 3 and the soluble microneedle patch 1.

[0053] Specifically, the soluble microneedle patch 1 includes a substrate 11 and a microneedle part 12. There are multiple microneedle parts 12 and they are arranged in an array on one side surface of the substrate 11. The microneedle part 12 is arranged facing away from the load-bearing hard plate 3, that is, the adhesive layer 4 is arranged between the substrate 11 and the load-bearing hard plate 3.

[0054] In this embodiment, in order to meet the needs of the product, a medical layer 5 with drug components is provided between the adhesive layer 4 and the load-bearing hard plate 3, so as to achieve the purpose that after the soluble microneedle patch 1 dissolves, the medical layer 5 can continue to dissolve and be absorbed by the skin, and has a certain auxiliary treatment effect.

[0055] In this embodiment, the pressure-applying strap 2 is also an elastic structure that can be extended and shortened. Moreover, the pressure-applying strap 2 includes a plurality of elastic telescopic segments 21 and a plurality of fixed-length segments 22. The elastic telescopic segments 21 are connected between two adjacent fixed-length segments 22, and the soluble microneedle patch 1 is relatively fixed on the fixed-length segments 22.

[0056] When the pressure-applying strap 2 is bundled and fixed on the human body, since the length of the fixed-length segment 22 will not change, the width of the fixed-length segment 22 will basically not narrow, which is beneficial to the fixed connection between the load-bearing hard plate 3 and the fixed-length segment 22.

[0057] Embodiment 4

[0058] Embodiment 4 of the present application discloses a strap-type soluble microneedle product. Refer to Figure 5 , the difference from Embodiment 3 is:

[0059] The widths of the load-bearing hard plate 3 and the soluble microneedle patch 1 are smaller than the width of the pressure-applying strap 2 to ensure that the pressure-applying strap 2 has a more comprehensive and firmer pressure effect on the soluble microneedle patch 1, so as to indirectly promote the dissolution and absorption of the soluble microneedle patch 1.

[0060] In this embodiment, in order to facilitate the connection and fixation of both ends of the pressing strap 2, the first fixing member 6 and the second fixing member 7 are respectively the sub-button and the mother-button of a snap button.

[0061] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the application shall be included in the protection scope of the present application.
