Description

Technical Field

[0001] The present invention relates to a skin treatment device using ultrasonic and high-frequency electromagnetic wave technologies related to the fields of biomedical engineering and electrical engineering, particularly dermatology.

Background Art

[0002] In modern society, the increasing concern for personal appearance is remarkable, and the beauty and health industry has rapidly developed from household skin care products to specialized treatments at beauty clinics and spas. Among the various devices used, there are two main principles that have continued conventionally:

[0003] Microcurrent electrophoresis (iontophoresis): This method enhances the permeability of cell membranes and enables deep penetration of charged molecules into skin tissues. Under the influence of an electric field generated by both electrodes, a low-frequency current is used to promote the movement of charged molecules.

[0004] Sonophoresis: This technology generates sound waves in the ultrasonic band and induces molecular vibrations. This vibration improves the absorption rate of various active ingredients. Furthermore, it promotes a mechanism that generates heat subcutaneously and further improves the absorption rate of active ingredients.

[0005] These principles are still widespread and have a considerable effect in delivering active ingredients to the skin. However, most of the related devices are large and mainly used in medical facilities or beauty clinics. However, due to the progress in miniaturization of such devices, more portable devices have been realized. As an example, the multifunctional device described in Patent Document CN111481820A aims to more effectively deliver active ingredients to the skin while ensuring safety and convenience without requiring manual operation. This device is designed in the form of a mask that can be directly attached to the skin without any manual operation.

[0006] Conventional inventions, such as those described in Patent Document KR2020110509A, primarily consisted of LED phototherapy masks. These inventions aimed to address problems encountered in conventional designs.

[0007] Furthermore, the popularity of addressing sagging facial skin has increased significantly. A commonly used method to address this problem is to apply low-frequency electrical current to induce heat subcutaneously. This heat causes collagen and elastin fibers to contract, stimulating the production of new collagen and elastin, ultimately resulting in a skin-tightening effect over time. [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] The challenge lies in addressing issues such as more effectively promoting the delivery of active ingredients to the skin than conventional methods, and inducing heat subcutaneously to stimulate the production of new collagen and elastin. [Means for solving the problem]

[0009] The wave energy irradiation device for skin according to the present invention has the following configuration:

[0010] External components: A mask (10) having two sides, one of which includes a wave transmission system (30) and the other a temperature sensor unit (60) on the skin contact side. All of these components are controlled by a controller (12) attached to the mask (10), which includes a switch (14) for turning the device on and off, and an indicator (16) for indicating the operating status of the device. The other end of the controller (12) is provided with a connection to a power supply (15) for supplying power to the entire device.

[0011] Internal Mechanism Elements: An ultrasonic generating unit (40), an electromagnetic wave generating unit (50), and a temperature sensor unit (60) are arranged inside the mask (10). These are securely assembled within the mask (10), which is made of a flexible material that can adapt to different facial contours. These components are controlled by a circuit board (70) consisting of an ultrasonic generating unit control subcircuit (71), an electromagnetic wave generating unit control subcircuit (72), a temperature processing subcircuit (73), a short-circuit protection subcircuit (74), and a Bluetooth / Wi-Fi signal transmission / reception subcircuit (75). All of these are powered by a power supply (80). [Effects of the Invention]

[0012] According to the present invention, the ultrasonic generating unit (40) irradiates the skin with ultrasound in the range of 20 kilohertz (kHz) to 20 megahertz (MHz), and the electromagnetic wave generating unit (50) irradiates the skin with electromagnetic waves in the range of 100 kilohertz (kHz) to 50 megahertz (MHz), thereby more effectively enhancing the penetration of active ingredients into the skin than conventional application methods. Furthermore, it induces heat in the subcutaneous tissue, stimulating the production of new collagen and elastin. The temperature sensor unit (60) monitors the skin temperature and immediately cuts off the current for safety if it exceeds the set limit. [Brief explanation of the drawing]

[Figure 3] This diagram shows the external features of the device from the rear. [Figure 4] This figure shows the characteristics and interconnections of the operating mechanism components of the device. [Figure 5] This figure shows a cross-sectional view and components of a wave transmission system and a temperature sensor unit. [Modes for carrying out the invention]

[0014] Overall configuration of the device

[0015] Referring to Figures 1, 2, and 3, the external components consist of a mask (10) that is curved to conform to the contours of the face and / or neck and features various protrusions and contours in different areas. It includes openings (20) for the eyes, nose, and mouth, and fastening or tightening straps (11) to prevent the mask from slipping off the face and / or neck without needing to be held manually at all times.

[0016] The mask (10) has two sides: one that is away from the skin and one that is in contact with the skin. A wave transmission system (30) and a temperature sensor unit (60) are integrated into the skin-contact side, both of which are connected to a controller (12). The controller (12) is integrated with the mask (10), and if it extends outside the mask (10), there are wires and / or data transmission cables (13) connecting the mask (10) and the controller (12).

[0017] Details of the internal mechanism

[0018] Referring to Figures 4 and 5, the internal mechanism elements are integrated with the external components and consist of a mask (10) made of a flexible and bendable material such as silicone, rubber, or plastic, which is formed to fit facial contours having various protrusions and contours in different regions.

[0019] Ultrasonic generating unit (40)

[0020] It consists of a piezoelectric element (41), which is responsible for converting electric current into ultrasonic energy and transmitting it to the skin. The upper part of the piezoelectric element (41) is connected to an electrode (31), and all these components are integrated within a mask material (90) made of a flexible and bendable material such as silicone, rubber, or plastic.

[0021] The ultrasonic generating unit (40) irradiates ultrasonic waves in the range of 20 kHz to 20 MHz, promotes the penetration of the active ingredient into the deep layer of the skin through molecular vibration, thereby enhancing the permeability of the active ingredient to cells. Furthermore, the ultrasonic waves also induce heat under the skin, which is another mechanism that promotes better penetration of the active ingredient into cells.

[0022] The electromagnetic wave generating unit (50)

[0023] is composed of electromagnetic wave electrodes (51) that irradiate electromagnetic waves on the skin. These electromagnetic wave electrodes (51) are connected to the electrodes (31) and are all integrated within a mask material (90) made of a flexible material such as silicone, rubber, or plastic.

[0024] The electromagnetic wave generating unit (50) irradiates electromagnetic waves having a frequency in the range of 100 kHz to 50 MHz, penetrates into the skin to generate heat, promotes the absorption of substances into the skin, and stimulates the production of collagen and elastin.

[0025] The temperature sensor unit (60)

[0026] is composed of a temperature sensor (61) that measures the skin temperature. This sensor is also integrated within the mask material (90) and is connected to the electrodes (31). The temperature sensor (61) measures the skin temperature and transmits the data to the temperature processing sub-circuit (73). When the skin temperature exceeds the safe level, the temperature processing sub-circuit (73) cuts off the current to prevent overheating.

[0027] The control system

[0028] The circuit board (70) includes the following sub-circuits:

[0029] The ultrasonic generating unit control sub-circuit (71)
