Description

Technical Field

[0001] This application relates to the field of soluble microneedle application technology, and in particular to a rod-shaped soluble microneedle massage device. Background Technology

[0002] Microneedle massage sticks utilize numerous tiny needles on a microneedle roller to stimulate the skin, allowing active ingredients to effectively penetrate the skin. When used with specialized products for wrinkle reduction, whitening, repair, stretch mark removal, and scar removal, they can achieve ideal results such as reducing wrinkles, treating scars and stretch marks, whitening the skin, reducing pigmentation, improving eye wrinkles and dark circles, and tightening and lifting facial skin tissue.

[0003] Soluble microneedle patches are mainly used in two categories. One category is primarily for cosmetic purposes, where the need for transdermal depth is not very high. The height of the needle tip is generally less than 300 micrometers, and the core material is mainly sodium hyaluronate, collectively referred to in the industry as micro-infiltration technology. The other category is primarily for transdermal drug delivery, where the need for transdermal depth is relatively high. The height of the needle tip is generally between 300 and 1500 micrometers. Based on the requirements of hardness and dissolution efficiency, the core material can also be PRA / PVA / PVC / PP / PLA, etc., collectively referred to in the industry as microcrystalline technology.

[0004] A search revealed that Chinese Patent Application No. 202120956489.5 discloses a soluble microneedle massage stick, which includes a handle, a massage roller, and a soluble microneedle patch. One end of the handle is provided with a fork, and the massage roller is rotatably mounted on the fork. The soluble microneedle patch includes a substrate and microneedles. The substrate is bonded to the outer peripheral wall of the massage roller, and the massage roller is detachably mounted on the fork mainly by snap-fit.

[0005] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0006] Common soluble microneedle massage sticks contain relatively small soluble microneedle patches, which are only suitable for facial skin care and transdermal treatment. However, for larger skin areas such as the abdomen, legs, and back, several massage sticks may be needed at once to fully treat a large area, making them unsuitable for large skin areas.

[0008] Common soluble microneedle massage sticks contain relatively small soluble microneedle patches, which are only suitable for facial skin care and transdermal treatment.

[0019] In one feasible technical solution of this application, the rolling rod is a metal part or a hard plastic part.

With two handles, it is easy for users to hold and fix the patch in place, enabling it to be rolled over larger skin areas. This makes it ideal for larger skin areas such as the abdomen, legs, and back, improving efficiency and reducing costs. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0032] This application discloses a rod-shaped soluble microneedle massage device. (Refer to...) Figure 1-2 The rod-shaped soluble microneedle massage device includes a rolling rod 1, a flexible sleeve 2, and a soluble microneedle patch 3. The flexible sleeve 2 is fixed to the middle of the rolling rod 1. Both ends of the rolling rod 1 extend from the flexible sleeve 2 to form a grip handle. The soluble microneedle patch 3 includes a substrate 31 and multiple needle tips 32. The needle tips 32 are integrally formed on the outer peripheral wall of the substrate 31. The substrate 31 is bonded to the outer peripheral wall of the flexible sleeve 2. The diameter of the soluble microneedle patch 3 is between 1.5 and 3 cm, and the length of the soluble microneedle patch 3 is between 5 and 10 cm.

[0033] To facilitate a secure connection between the rolling rod 1 and the flexible sleeve 2, a fixing ring 4 is fixedly installed on the outer peripheral wall of the rolling rod 1. The fixing ring 4 is coaxially arranged with the rolling rod 1 and is used to block one end of the flexible sleeve 2. A clamping ring 5 that blocks the other end of the flexible sleeve 2 can also be detachably installed on the rolling rod 1.

[0034] Furthermore, in order to facilitate the disassembly and adjustment of the clamping ring 5 to cooperate with the fixing ring 4 to clamp and fix the flexible sleeve 2 in the middle, the rolling rod 1 is provided with an external thread section 11, and the inner circumferential wall of the clamping ring 5 is provided with an internal thread, and the clamping ring 5 is threadedly assembled on the external thread section 11.

[0035] The clamping ring 5 and the fixing ring 4 have the same outer diameter, and the outer diameter of the fixing ring 4 is larger than the outer diameter of the flexible sleeve 2. An inner ring groove is formed between the fixing ring 4, the clamping ring 5 and the flexible sleeve 2. The depth of the inner ring groove is the same as the thickness of the substrate 31. The design of the inner ring groove facilitates the rapid positioning of the soluble microneedle patch 3 when it is bonded to the flexible sleeve 2, which is conducive to the efficient assembly of this product.

[0036] In this embodiment, the wall thickness of the flexible sleeve 2 is between 3 and 5 mm, and the flexible sleeve 2 is made of soft rubber or silicone. The inner peripheral wall of the flexible sleeve 2 is provided with friction texture for anti-slip. The flexible sleeve 2 designed above has a certain degree of elasticity. When rolling on the skin, the soluble microneedle patch 3 will fit the skin surface more closely and significantly improve the comfort of use.

[0037] Furthermore, the maximum diameter of the rolling rod 1 is between 1 and 2 centimeters, and the length of the rolling rod 1 is between 25 and 30 centimeters.

[0038] To improve the comfort and stability of the user's grip on the scroll bar 1, the grip handle includes a connecting part 12, a recessed part 13, and an outer end 14. The connecting part 12 is adjacent to the flexible sleeve 2, and the recessed part 13 is located between the connecting part 12 and the outer end 14. The outer diameter of the outer end 14 gradually decreases from the recessed part 13 to the outer end 14, and the outer diameter of the recessed part 13 gradually increases from the connecting part 12. Anti-slip textures are provided on the outer peripheral walls of both the recessed part 13 and the outer end 14.

[0039] Specifically, the height of the needle tip 32 is 200-500 micrometers, the base diameter of the needle tip 32 is 100-1500 micrometers, the distance between the tips of two adjacent needle tips 32 is 200-2000 micrometers, and the needle tip 32 is a conical structure, a triangular pyramidal structure, or a quadrangular pyramidal structure. The rolling rod 1 is a metal part or a hard plastic part to ensure its structural strength.

[0040] The beneficial technical effects of the rod-shaped soluble microneedle massage device according to the embodiments of this application are roughly as follows:

[0041] This rod-shaped structure differs from the common roller design, allowing the soluble microneedle patch 3 to be made larger. With two handles, it is easy for users to hold and fix it in place with both hands, so that it can be rolled on larger skin areas. It is very suitable for large skin areas such as the abdomen, legs, and back, improving efficiency and reducing cost.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
