Description

Technical Field

[0001] This invention relates to the field of epidermal drug delivery technology, specifically to a skin care device. Background Technology

[0002] Transdermal drug delivery (TDD) is an important method of drug delivery, transporting drugs to local tissues or the systemic circulation through the skin. Compared with traditional oral and injectable administration, it has significant advantages such as avoiding the first-pass effect of the liver, reducing gastrointestinal irritation, improving patient compliance, and providing stable and sustained blood drug concentrations. It is widely used in many medical fields such as dermatology, pain management, hormone replacement therapy, and cardiovascular diseases.

[0003] However, the skin itself, as the body's natural barrier, has an outermost stratum corneum that provides extremely strong resistance to the penetration of most drugs, especially large molecules, hydrophilic drugs, or highly charged drugs. This "barrier effect" severely restricts the efficiency of transdermal drug absorption, resulting in limited dosage, slow onset of action, and low bioavailability. This prevents many drugs with good pharmacological activity from achieving effective treatment through epidermal administration. Therefore, we propose a skin care device to address the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a skin care device that solves the core drawbacks of traditional epidermal drug delivery, such as the strong resistance of the stratum corneum to drug penetration, resulting in poor drug penetration, low transdermal absorption efficiency, poor bioavailability, and slow onset of action. At the same time, it improves upon the problems of traditional drug delivery methods, which require multiple devices for operation, are cumbersome, and result in uneven drug application, waste, or skin irritation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a skin care device, comprising a housing;

[0006] The housing is provided with a mounting base, and a connecting shaft is provided between the mounting base and the housing;

[0021] Beneficial effects

[0022] This invention provides a skin care device. Compared with the prior art, it has the following advantages:

[0023] This skin care device uses a microneedle disc that moves up and down to allow microneedles to penetrate the stratum corneum and reach the dermis, directly creating microchannels within the skin and overcoming the stratum corneum's resistance to drug penetration. Whether the drug is macromolecular, hydrophilic, or highly charged, it can quickly penetrate deep into the skin through these channels, effectively solving the core problem of traditional epidermal drug delivery where drugs struggle to penetrate the stratum corneum. The channels created by the microneedles are temporary and minimally invasive, ensuring effective drug penetration without causing serious skin damage. Post-procedure skin recovery is rapid, and the device is highly safe.

[0024] The rotating design of the application disc allows the ointment to be evenly applied to the target skin area, avoiding local accumulation or omissions and ensuring full contact between the drug and the skin surface, laying a good foundation for subsequent drug penetration. The heat generated by the heating pad can soften the stratum corneum, reduce drug penetration resistance, and promote local blood circulation, accelerating the diffusion and absorption of the drug in the skin, helping the drug to exert its pharmacological effects more fully and effectively solving the problem of low bioavailability of traditional epidermal drug delivery.

[0025] The microneedle channel, combined with uniform application and heating assistance, creates a synergistic effect of application, heating, and penetration, significantly improving the efficiency of transdermal drug absorption. This results in faster onset and longer-lasting effects, further expanding the range of drugs that can be administered through the epidermis. In terms of ease of operation and adaptability, the device integrates multiple functions such as application, heating, massage, and microneedle penetration. Users can flexibly switch between function modes using control buttons according to drug characteristics, skin condition, and treatment needs, without having to replace multiple devices, greatly simplifying the epidermal drug delivery process.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1-4 As shown:

[0034] A skin care device includes a housing 101;

[0035] A mounting base 105 is provided inside the housing 101, and a connecting shaft 104 is provided between the mounting base 105 and the housing 101;

[0036] A handle 102 is fixedly mounted on the upper surface of the housing 101. A control button 103 is mounted on the handle 102. One end of the connecting shaft 104 is fixedly connected to the housing 101, and the other end is rotatably connected to the mounting base 105 through a bearing.

[0037] A storage battery 111 is installed in the third cavity of the housing 101, and a charging interface 112 is provided on the mounting base 105.

[0038] A folding locking mechanism 2, integrated into the housing 101 and the mounting base 105, is used to lock the position of the folded mounting base 105. The folding locking mechanism 2 includes a U-shaped rod 203 that slides on the handle 102. A pressing plate 201 is fixedly installed at the top of the U-shaped rod 203, and a pin 205 is fixedly installed at the bottom of the U-shaped rod 203. A rotating disk 204 is fixedly installed on the side of the mounting base 105 near one of the connecting shafts 104. The rotating disk 204 and the connecting shaft 102 are connected to the handle 105. 4. Concentric arrangement: The surface of the rotating disk 204 is provided with a locking groove 206 that matches the pin 205. There are two sets of locking grooves 206, which are symmetrically arranged. The surface of the U-shaped rod 203 is fitted with a first spring 202 arranged symmetrically. The two ends of the first spring 202 are fixedly connected to the pressing plate 201 and the handle 102 respectively. The housing 101 and the handle 102 are both provided with a moving hole that matches the U-shaped rod 203. The U-shaped rod 203 can slide up and down in the moving hole.

[0039] The folding locking mechanism 2 also includes a limiting rod 207 fixed on the surface of one of the connecting shafts 104, and a limiting groove 208 adapted to the limiting rod 207 is provided on one side of the rotating disk 204.

[0040] The first connecting plate 108 is rotatably mounted on the bottom of the mounting base 105 via a bearing in the first cavity. A heating element 107 is mounted on the lower surface of the first connecting plate 108. An applicator 106 is detachably mounted below the first connecting plate 108.

[0041] The top of the mounting base 105 has a second connecting plate 109 provided in the second cavity, and a microneedle plate 110 is detachably mounted on the upper surface of the second connecting plate 109.

[0042] Drive mechanism 3, integrated into the third cavity of the mounting base 105, is used to drive the first connecting plate 108 to rotate and the second connecting plate 109 to move up and down. Drive mechanism 3 includes an electric push rod 301 installed in the third cavity of the mounting base 105. A connecting plate 302 is fixedly installed at the output end of the electric push rod 301. A rack 303 is fixedly installed on one side of the connecting plate 302. A gear 305 is meshed with the tooth surface of the rack 303. The first connecting plate 108 is connected to the gear 305 through a connecting shaft. The third cavity of the mounting base 105... The three cavities are also provided with a strip plate 309. A second telescopic rod 310 arranged symmetrically is fixed between the strip plate 309 and the mounting base 105. A second spring 311 is wound around the surface of the second telescopic rod 310. A connecting column is fixed between the strip plate 309 and the second connecting plate 109. An inclined block 308 is fixedly installed on the lower surface of the strip plate 309. An L-shaped rod 306 is fixedly installed on the upper surface of the rack 303. A sleeve rod 307 is rotatably installed on the L-shaped rod 306 through a bearing. A first telescopic rod 304 is fixed between the rack 303 and the mounting base 105.

[0043] The 106 applicator can be used as a massage disc.

[0044] In this implementation scheme: When the skin care device is in use, when the device is not in use, the mounting base 105 is fixed in its initial position by the folding locking mechanism 2. At this time, the application plate 106 faces down, the microneedle plate 110 faces up, and the bottom opening of the housing 101 corresponds to the position of the application plate 106 at the bottom of the mounting base 105.

[0045] The user first applies the required ointment evenly to the designated skin area, then holds the handle 102 and ensures that the control button 103 on the handle 102 is easy to operate. At the same time, the user checks whether the charging port 112 on the mounting base 105 has been powered by the battery 111 to ensure that the device has sufficient power when it is running.

[0046] The user presses the corresponding control button 103 on the grip 102 to start the electric push rod 301 in the drive mechanism 3. At this time, the battery 111 supplies power to the electric push rod 301, and the output end of the electric push rod 301 drives the connecting plate 302 to perform linear reciprocating motion.

[0047] When the connecting plate 302 moves, the rack 303 fixedly connected to it moves synchronously. The first telescopic rod 304 between the rack 303 and the mounting base 105 plays a guiding and stabilizing role, ensuring that the rack 303 moves smoothly in a fixed direction.

[0048] The tooth surfaces of rack 303 mesh with gear 305, converting the linear reciprocating motion of rack 303 into the forward and reverse rotation of gear 305. Since the first connecting disc 108 is fixedly connected to gear 305 via a connecting shaft, the forward and reverse rotation of gear 305 drives the first connecting disc 108 to rotate synchronously in both directions.

[0049] The application plate 106, which can be detachably installed on the lower surface of the first connecting plate 108, rotates in both directions along with the first connecting plate 108. During the rotation, the application plate 106 comes into full contact with the ointment on the skin surface, spreading the ointment that was originally applied to the skin surface evenly, ensuring that the ointment covers the entire target treatment area.

[0050] If the user needs to add a massage effect during the application process, the application plate 106 can be replaced with a massage plate. While the application plate 106 rotates in both directions, it can massage the skin and promote local blood circulation.

[0051] During or before and after applying the ointment, the user can turn on the heating pad 107 installed on the lower surface of the first connecting plate 108 via the control button 103;

[0052] When the heating pad 107 is powered on, it generates heat. This heat is transferred through the first connecting plate 108 to the application plate 106, and then from the application plate 106 to the skin surface. The heat from the heating pad 107 moderately raises the skin surface temperature, softening the stratum corneum and laying the foundation for subsequent drug penetration. It also improves the skin's absorption efficiency of the ointment, enhancing the treatment effect. Users can adjust the heating temperature of the heating pad 107 according to their own skin tolerance using the control button 103.

[0053] After completing the ointment application and / or heat treatment, if further enhancement of drug penetration is required, the folding locking mechanism 2 can be activated to switch to microneedle treatment mode. The user presses the press plate 201 in the folding locking mechanism 2. The press plate 201 drives the U-shaped rod 203 to slide downward along the moving hole on the housing 101 and the handle 102. The first spring 202 sleeved on the surface of the U-shaped rod 203 is compressed. The pin 205 at the bottom of the U-shaped rod 203 moves downward with the U-shaped rod 203 and disengages from the locking groove 206 on the surface of the rotating disk 204, releasing the position lock of the mounting base 105.

[0054] The user holds the mounting base 105 and rotates the mounting base 105 around the connecting shaft 104. During the rotation, the limiting rod 207 on the surface of the connecting shaft 104 slides in the limiting groove 208 on one side of the rotating disk 204. When the mounting base 105 rotates 180 degrees, the limiting rod 207 abuts against the other end of the limiting groove 208, restricting the mounting base 105 from continuing to rotate.

[0055] At this time, the pressing plate 201 is released, the first spring 202 returns to its elastic deformation, pushing the U-shaped rod 203 upward, and the pin 205 is re-inserted into the other set of symmetrically arranged locking grooves 206 of the rotating disk 204, completing the 180-degree flip locking of the mounting base 105. At this time, the microneedle disk 110 faces downward, and the bottom opening of the housing 101 is aligned with the skin surface. The user presses the control button 103 again to start the electric push rod 301. The electric push rod 301 drives the connecting plate 302 and the rack 303 to move. The L-shaped rod 306 fixed on the upper surface of the rack 303 moves synchronously. The sleeve rod 307, which is rotatably mounted on the L-shaped rod 306 through the bearing, contacts and slides relative to the inclined block 308 on the lower surface of the strip plate 309. The sleeve rod 307 generates an upward pushing force on the inclined block 308, driving the strip plate 309. When plate 309 moves upward, the second telescopic rod 310 between strip plate 309 and mounting base 105 is stretched. The second spring 311 wound around the surface of the second telescopic rod 310 deforms synchronously. Strip plate 309 drives second connecting plate 109 to move upward through connecting column. When electric push rod 301 moves in the opposite direction, L-shaped rod 306 and sleeve rod 307 move in the opposite direction. Second spring 311 recovers elastic deformation, pulls strip plate 309 downward, and then drives second connecting plate 109 downward. Microneedle disc 110, which can be detachably installed on the upper surface of second connecting plate 109, moves up and down with second connecting plate 109. During the up and down movement, microneedles on microneedle disc 110 penetrate the outermost stratum corneum of skin to the dermis, forming microchannels in the skin and breaking the skin's natural barrier.

[0056] The tiny channels within the skin provide a penetration pathway for the drug components in the ointment, enabling the drug to quickly and efficiently enter the deep tissues of the skin or circulate throughout the body, thereby improving the bioavailability of the drug.

[0057] This approach utilizes the up-and-down movement of the microneedle disc 110 to allow microneedles to penetrate the stratum corneum and reach the dermis, directly creating microchannels within the skin and overcoming the stratum corneum's resistance to drug penetration. Whether the drug is macromolecular, hydrophilic, or highly charged, it can rapidly penetrate the deep layers of the skin through these channels, effectively solving the core problem of drug penetration into the stratum corneum in traditional epidermal drug delivery. The channels created by the microneedles are temporary and minimally invasive, ensuring effective drug penetration without causing serious skin damage. Post-procedure skin recovery is rapid, and the procedure is highly safe.

[0058] The rotating design of the application disc allows the ointment to be evenly applied to the target skin area, avoiding local accumulation or omissions and ensuring full contact between the drug and the skin surface, laying a good foundation for subsequent drug penetration. The heat generated by the heating pad can soften the stratum corneum, reduce drug penetration resistance, and promote local blood circulation, accelerating the diffusion and absorption of the drug in the skin, helping the drug to exert its pharmacological effects more fully and effectively solving the problem of low bioavailability of traditional epidermal drug delivery.

[0059] The microneedle channel, combined with uniform application and heating assistance, creates a synergistic effect of application, heating, and penetration, significantly improving the efficiency of transdermal drug absorption, making the drug take effect faster and longer-lasting, and further expanding the range of drugs that can be administered through the epidermis. In terms of ease of operation and adaptability, the device integrates multiple functions such as application, heating, massage, and microneedle penetration. Users can flexibly switch between function modes through the control button according to the characteristics of the drug, skin condition, and treatment needs, without having to change multiple devices, greatly simplifying the epidermal drug delivery process.

[0060] It should be noted that the temperature of the heating pad can be adjusted via the control button, allowing users to select a suitable temperature based on their skin tolerance to prevent burns. The microneedle disc 110 can be designed for single use depending on actual needs.

[0061] It should be noted that the solution also includes a control module, which is installed on the mounting base 105. During use, each electrical device can be started and operated separately through the electrical control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to those in the field, so it will not be elaborated further here.

[0062] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0063] like Figure 5 As shown:

[0064] In an optional embodiment, the housing 101 adopts a planar partition structure design, and a cooling and temperature control device 115 is provided on the housing 101. A sterile container 114 is detachably connected to the bottom of the housing 101. The sterile container 114 contains a solvent for skin care, cleaning, wound cleaning, anesthesia, drug administration or sedation. The sterile container 114 is made of a non-rigid material and has reinforced holes on its edges. A corresponding protrusion 113 is provided on the housing 101. After the protrusion 113 passes through the reinforced holes, it can quickly lock the sterile container 114 to the housing 101.

[0065] In this embodiment: the handle 102 and the sterile container 114 are physically isolated by the planar partition structure of the housing 101, avoiding contact between the operator's hands and the sterile area; the cooling and temperature control device 115 can apply ice to the skin during drug administration to soothe it and reduce discomfort caused by microneedle puncture, which is particularly suitable for the treatment of wounds, inflammation or postoperative sensitive skin; the sterile container 114 achieves quick replacement of sterile consumables through the quick locking cooperation between the protrusion 113 and the reinforced hole, meeting the rapid response needs in emergency or emergency scenarios, and effectively improving the applicability and operational safety of the device.

[0066] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
