Description

Technical Field

[0001] This application relates to the field of soluble microneedle application technology, and in particular to an intelligent 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] When the soluble microneedle massage stick is rolled on the skin, a certain amount of force needs to be applied to the handle to ensure that the needle tips of the soluble microneedle patch can achieve transdermal absorption. Some users, due to insufficient proficiency, may apply too little or too much pressure to the hollow handle, which can easily lead to insufficient transdermal absorption or excessive pressure on the skin, both of which are not conducive to the dissolution and absorption of the soluble microneedle patch. Utility Model Content

[0007] This application provides an intelligent soluble microneedle massage device to improve the following technical problems:

[0008] When the soluble microneedle massage stick is rolled on the skin, a certain amount of force needs to be applied to the handle to ensure that the needle tips of the soluble microneedle patch can achieve transdermal absorption. Some users, due to insufficient proficiency, may apply too little or too much pressure to the hollow handle, which can easily lead to insufficient transdermal absorption or excessive pressure on the skin, both of which are not conducive to the dissolution and absorption of the soluble microneedle patch.

[0009] This application provides an intelligent soluble microneedle massage device, which adopts the following technical solution:

[0010] A smart soluble microneedle massage device includes a hollow handle, a hollow fork, a massage roller, and soluble microneedle patches. The hollow fork is located at one end of the hollow handle, and the massage roller is rotatably mounted inside the fork. The soluble microneedle patches are adhered to the outer peripheral wall of the massage roller. The rotation axis of the massage roller is perpendicular to the central axis of the hollow handle. Rotating shafts are provided at both ends of the massage roller. A mounting hole is provided on the hollow fork, and an annular pressure sensor is installed within the mounting hole. The rotating shaft is inserted into and rotatably mounted in the annular pressure sensor. A vibration motor, a control circuit board, and a battery are housed inside the hollow handle. The control circuit board is electrically connected to the annular pressure sensor, the vibration motor, and the battery. Wiring grooves are provided inside the hollow handle and the hollow fork. When the annular pressure sensor detects that the pressing pressure exceeds a preset pressure threshold, the vibration motor is activated by the control circuit board.

[0011] In one feasible technical solution of this application, the vibration motor is a magnetic levitation acoustic motor, and the maximum diameter of the magnetic levitation acoustic motor does not exceed 1 cm, and the maximum length of the magnetic levitation acoustic motor does not exceed 3 cm.

[0012] In one feasible technical solution of this application, the vibration frequency of the vibration motor is between 10,000 and 25,000 times per minute.

[0013] In one feasible technical solution of this application, the battery is a rechargeable battery, and a charging interface is provided at the end of the hollow handle away from the hollow fork opening.

[0014] In one feasible technical solution of this application, the vibration motor, the control circuit board, the storage battery and the charging interface are arranged in sequence, and the four are located on the central axis of the hollow handle.

[0015] In one feasible technical solution of this application, the annular pressure sensor is model LFE-04, the output sensitivity of the annular pressure sensor is 1.5±10%mV / V, the operating voltage of the annular pressure sensor is 3-5V, and the body of the annular pressure sensor is made of stainless steel.

[0016] In one feasible technical solution of this application, the soluble microneedle patch includes a substrate and a plurality of needle tips, wherein the needle tips are integrally formed on the outer peripheral wall of the substrate.

[0017] In one feasible technical solution of this application, the massage roller includes an inner cylinder and a flexible sleeve. The flexible sleeve is sleeved and fixed on the inner cylinder, and the soluble microneedle patch is adhered to the outer peripheral wall of the flexible sleeve. The flexible sleeve is a soft rubber part or a silicone part.

[0018] In one feasible technical solution of this application, an annular groove is provided on the outer peripheral wall of the inner cylinder, and the flexible sleeve is embedded in the annular groove. The depth of the annular groove is the sum of the thickness of the flexible sleeve and the thickness of the substrate.

[0019] In one feasible technical solution of this application, the hollow handle is provided with arc-shaped grooves on both sides to accommodate finger clamping.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] During product use, even if the user is not proficient in operation, the ring pressure sensor can detect at any time whether the pressing pressure exceeds the preset pressure threshold. When the pressing pressure is too high or too low, the vibration motor is controlled by the control circuit board to start working, thereby reminding the user that the pressing pressure is inappropriate. This prevents insufficient transdermal penetration or excessive pressure on the skin, which is conducive to the dissolution and absorption of soluble microneedle patches and makes the process more convenient.

[0038] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0039] This application discloses an intelligent soluble microneedle massage device. (Refer to...) Figure 1 The intelligent soluble microneedle massage device includes a hollow handle 1, a hollow fork section 2, a massage roller 3, and soluble microneedle patches 4. The hollow fork section 2 is located at one end of the hollow handle 1. The massage roller 3 is rotatably mounted inside the fork section. The soluble microneedle patches 4 are adhered to the outer peripheral wall of the massage roller 3. The rotation axis of the massage roller 3 is perpendicular to the central axis of the hollow handle 1. The two ends of the massage roller 3 are provided with rotating shafts 33. The hollow fork section 2 is provided with mounting holes, and an annular pressure sensor 5 is installed in the mounting holes. The rotating shafts 33 are inserted into and rotatably mounted in the annular pressure sensor 5. The hollow handle 1 contains a vibration motor 6, a control circuit board 7, and a battery 8. The control circuit board 7 is electrically connected to the annular pressure sensor 5, the vibration motor 6, and the battery 8. The hollow handle 1 and the hollow fork section 2 are provided with wiring grooves. When the annular pressure sensor 5 detects that the pressing pressure exceeds the preset pressure threshold, the vibration motor 6 is controlled by the control circuit board 7 to start working.

[0040] The vibration frequency of the vibration motor 6 is between 10,000 and 25,000 times per minute, thus providing a good reminder effect. In order to fit the narrow installation space inside the hollow handle 1, the vibration motor 6 is a magnetic levitation sonic motor, and the maximum diameter of the magnetic levitation sonic motor does not exceed 1 cm, and the maximum length of the magnetic levitation sonic motor does not exceed 3 cm.

[0041] In this embodiment, the battery 8 is a rechargeable battery, and the end of the hollow handle 1 away from the hollow fork 2 is provided with a charging interface 9. Specifically, the arrangement is as follows: the vibration motor 6, the control circuit board 7, the battery 8 and the charging interface 9 are arranged in sequence, and the four are located on the central axis of the hollow handle 1.

[0042] In this embodiment, the ring pressure sensor 5 is model LFE-04, the output sensitivity of the ring pressure sensor 5 is 1.5±10%mV / V, the operating voltage of the ring pressure sensor 5 is 3-5V, and the main body of the ring pressure sensor 5 is made of stainless steel.

[0043] Furthermore, the soluble microneedle patch 4 includes a substrate 41 and a plurality of needle tips 42, the needle tips 42 being integrally formed on the outer peripheral wall of the substrate 41.

[0044] In this embodiment, the massage roller 3 includes an inner cylinder 31 and a flexible sleeve 32. The flexible sleeve 32 is sleeved and fixed on the inner cylinder 31. The soluble microneedle patch 4 is adhered to the outer peripheral wall of the flexible sleeve 32. The flexible sleeve 32 is a soft rubber part or a silicone part. Moreover, an annular groove is provided on the outer peripheral wall of the inner cylinder 31. The flexible sleeve 32 is embedded in the annular groove. The depth of the annular groove is the sum of the thickness of the flexible sleeve 32 and the thickness of the substrate 41.

[0045] The flexible sleeve 32 has a certain degree of elasticity. When the massage roller 3 is rolled on the skin, the soluble microneedle patch 4 will fit the skin surface better and significantly improve the comfort of use.

[0046] To facilitate user gripping of the fixed hollow handle 1, the hollow handle 1 has arc-shaped grooves 11 on both sides for finger clamping.

[0047] The beneficial technical effects of the intelligent soluble microneedle massage device according to the embodiments of this application are roughly as follows:

[0048] The pressure between the ring pressure sensor 5 and the rotating shaft 33 can indirectly reflect the pressure applied when the soluble microneedle patch 4 contacts the skin. During the rolling use of the product, even if the user is not skilled in operation, the ring pressure sensor 5 can detect at any time whether the pressure exceeds the preset pressure threshold. When the pressure is too high or too low, the vibration motor 6 is controlled by the control circuit board 7 to start working, thereby reminding the user that the pressure is inappropriate. This prevents insufficient transdermal penetration or excessive pressure on the skin, which is conducive to the dissolution and absorption of the soluble microneedle patch 4 and makes it more convenient.

[0049] 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.
