A treatment device for skin diseases using multi-frequency ultrasonic waves

Abstract

The present invention relates to a therapeutic device that emits multi-frequency ultrasound, and more specifically, to a skin disease treatment device capable of alternately or selectively emitting ultrasound of multiple frequency bands within the range of 0.6 MHz to 20 MHz from an ultrasound transducer when performing ultrasound treatment using an ultrasound transducer in contact with the surface of human skin, particularly the skin of the face. Unlike conventional ultrasound transducers that emit only ultrasound of a single frequency band, a single ultrasound transducer is used that alternately or selectively emits ultrasound of multiple frequency bands within the range of 0.6 MHz to 20 MHz. Specifically, a high-frequency generating ultrasound transducer that generates a waveform with a large amplitude and a short period (high frequency band), a low-frequency generating ultrasound transducer that generates a waveform with a relatively smaller amplitude and longer period than the high-frequency generating ultrasound transducer (low frequency band), and a medium-frequency generating ultrasound transducer in the intermediate frequency band can be replaced by a single ultrasound transducer. Since high-frequency, medium-frequency, and low-frequency ultrasounds can be selectively or alternately generated, this device is suitable for specialized skin hospitals or skin massage clinics. Since it is possible to perform skin treatment with optimal ultrasound using a minimal number of ultrasound devices without having to equip a business with various types of ultrasound devices, individuals, specialized skin clinics, or specialized skin massage businesses can minimize the purchase cost of ultrasound devices and reduce maintenance costs. Additionally, by generating high-frequency, medium-frequency, and low-frequency ultrasounds tailored to the lesions, it can have an excellent effect in treating lesions that have been difficult to treat until now, such as intractable rosacea and acne.

Description

Technology Field

[0001] The present invention relates to a therapeutic device that emits multi-frequency ultrasound, and more specifically, to a skin disease treatment device that can simultaneously emit or selectively emit ultrasound of multiple frequency bands in the range of 0.6 MHz to 20 MHz from an ultrasound transducer when performing ultrasound treatment using an ultrasound transducer in contact with the surface of the skin of the human body, particularly the skin of the face. Background Technology

[0002] Generally, the condition of the skin is an important factor in appearance, so women pay great attention to skin care, and recently, interest in skin care is also growing among men.

[0003] Meanwhile, various cosmetics are being used for skin care, and skin massage has also become a means of skin care. Although one can perform skin care massage manually, such self-administered massage is merely basic; therefore, many people recently visit specialized hospitals or establishments equipped with various types of skin massage and treatment devices to receive professional skin care massages.

[0004] In this way, when visiting a specialized skin clinic or a professional skin massage establishment to receive a massage, one can receive various types of skin massages using diverse massage and treatment devices, allowing for satisfactory results compared to performing the massage manually oneself.

[0005] However, when visiting specialized dermatology clinics or massage parlors to receive skin massages, there was the problem of significant travel time and the financial burden involved.

[0006] Furthermore, there are lesions that are difficult to treat even with the use of skin care and treatment devices; in particular, refractory rosacea is difficult to treat, and various studies are already being conducted to address this. Additionally, research is underway regarding various skin conditions, such as wrinkles, skin damage, scars, aging, acne, melasma, and skin whitening.

[0007] To address the aforementioned issues, various types of skin massagers that users can easily operate have recently been proposed. These user-friendly skin massagers are rapidly becoming widespread because they not only offer superior effectiveness compared to manual massage but also reduce the time and cost burden associated with visiting specialized skin clinics or massage salons.

[0008] Meanwhile, ultrasound refers to sound that vibrates too fast for humans to hear, and in engineering terms, it refers to sound that vibrates more than 20,000 times per second. Essentially, it has the same properties as sound waves in the audible range, but because its wavelength is short, it generates significantly strong vibrations and has the characteristic of having a strong force to shake materials. In addition to the properties of sound, ultrasound also possesses the properties of radio waves and light. The aforementioned ultrasound is used in various fields such as ultrasonic cleaners, ultrasonic humidifiers, fish finders, ultrasonic welding, ultrasonic tomography, and ultrasonic diagnostic equipment. In particular, when ultrasound is transmitted to the human body, it reaches a depth of several centimeters (4 to 5 cm), and since its effect is similar to a massage, it is applied to ultrasonic therapy devices used as a medical physical therapy method to treat arthritis, rheumatism, back pain, post-traumatic pain, and neuralgia. Furthermore, lowering the frequency of such ultrasound generates soft ultrasound for skin care, and an ultrasonic skin massager is a device that utilizes this for beauty purposes.

[0009] The principle of the above-described ultrasonic skin massager is to irradiate the skin with optimal soft ultrasound (vibrations that cannot be felt by the skin but are extremely fast at 1 million Hz), and the ultrasound acts to apply instantaneous pressure fluctuations to blood vessels, cells, and lymphatic vessels up to the skin surface or 4 to 5 cm below the skin surface, thereby performing a high-speed massage action. It activates the skin by promoting the metabolism of skin tissues through a cleansing action that removes impurities deep within the sweat pores and a thermal action that warms the deep parts of the skin to promote the flow of blood or lymph. Generally, a ceramic ultrasonic vibration element (vibration probe) is directly attached to a proboscis head made of a metal case, and ultrasound of a certain frequency is applied for a set period of time to generate an oscillation output, which is converted into vibration and applied for the treatment or beauty of the entire body or facial skin.

[0010] However, conventional skin massagers and skin treatment devices using a single ceramic ultrasonic vibration element have a problem in that they do not show significant therapeutic effects in treating specific lesions such as intractable rosacea and acne, because they emit only ultrasound within a specific frequency range among various frequency bands.

[0011] Furthermore, there are inefficiencies due to the unreasonable requirement for users to purchase each treatment device individually and spatial limitations resulting from the purchase of multiple pieces of equipment.

[0012] Furthermore, there are conditions that are difficult to treat with existing devices; in particular, intractable flushing, acne, wrinkles, skin damage, scars, aging, melasma, and skin whitening present significant challenges when treated with conventional equipment. The problem to be solved

[0013] The present invention aims to provide a skin disease treatment device that addresses the aforementioned problems, which are difficult to treat with conventional technology, by configuring the technology to control the depth of ultrasonic energy penetrating the skin through a conversion of the frequency of ultrasonic emission, thereby enabling the treatment of difficult-to-treat lesions such as intractable rosacea and acne, and also providing excellent effects in treating wrinkles, skin damage, scars, aging, melasma, and skin whitening. means of solving the problem

[0014] The solution of the present invention for achieving the above objective comprises a handle (2) formed in a shape that a user can hold, a power cable (50) provided on one side of the handle (2), a vibrator part (1) located on the other side of the handle (2), and a main body (4) including an LED (3) formed on the surface of the handle (2).

[0015] The handle (2) and the vibrator part (1) formed on the other side of the handle (2) can be combined and separated, and a vibrator (20) is formed in the inner central part of the vibrator part (1), and a PCB board (60) and an electrode needle (40) are formed on the inner side of the other side of the handle (2).

[0016] One electrode needle (40) is formed on the upper surface of the PCB board (60), and the electrode needle (40) can be adjusted in length in a two-stage structure by forming a spring on the inner side of the electrode needle (40), so that a restoring force is generated by the spring, causing the electrode needle (40) to come into close contact with the vibrator (20), and the cable directly connected to the vibrator (20) is connected to the vibrator part (1).

[0017] The PCB board (60) is configured to include a power supply unit (81) that applies power to the electrode needle (40) through a power cable (50), a control unit (82) that controls components formed in the main body (4), an ultrasonic switching unit (83) that converts the ultrasonic waves generated from the vibrator (20) into high frequency or low frequency, and an ultrasonic output voltage boosting unit (87) that adjusts the voltage applied to the electrode needle (40) through the power supply unit (81).

[0018] The low-frequency ultrasound generated by the above vibrator (20) is in the frequency range of 0.6 to 3 MHz, the medium-frequency ultrasound is in the frequency range of 3 to 7 MHz, and the high-frequency ultrasound is in the frequency range of 7 to 20 MHz. The above LED (3) is illuminated with a specific color LED (3) when high-frequency ultrasound is generated or when medium-frequency or low-frequency ultrasound is generated, so that the frequency range of the current ultrasound can be recognized in real time.

[0019] When power is input to the power cable (50) constituting the main body (4), the AC voltage input from the power supply unit (81) included in the PCB board (60) is converted into DC voltage.

[0020] As described above, the DC voltage converted by the power supply unit (81) is input to the ultrasonic switching unit (83) and the ultrasonic output voltage boosting unit (87).

[0021] At this time, the control of the PCB board (60) is in the control unit (82), and the control unit (82) manages the operation of the power supply unit (81), the ultrasonic switching unit (83), and the ultrasonic output voltage boosting unit (87).

[0022] The control unit (82) controls the ultrasonic switching unit (83) by means of a pre-programmed program to switch low-frequency ultrasonic waves of 0.6 to 3 MHz, medium-frequency ultrasonic waves of 3 to 7 MHz, and high-frequency ultrasonic waves of 7 to 20 MHz, and transmits frequency input values ​​corresponding to each function from the ultrasonic switching unit (83) to the ultrasonic output voltage boosting unit (87), thereby generating an output voltage corresponding to the corresponding frequency input value in the ultrasonic output voltage boosting unit (87).

[0023] The above PCB board (60) converts the input DC voltage into a switching voltage and, under the control of the control unit (82), generates an output voltage by boosting the switching voltage to generate ultrasound corresponding to each frequency value.

[0024] The output voltage generated above can alternately or selectively generate low-frequency ultrasound in the range of 0.6 to 3 MHz, medium-frequency ultrasound in the range of 3 to 7 MHz, and high-frequency ultrasound in the range of 7 to 20 MHz through the electrode needle (40) and the vibrator (20).

[0025] Preferably, it is possible to emit ultrasound in eight frequency bands, and specifically, ultrasonic transducers of 0.6 MHz, 1 MHz, 2 MHz, and 2.8 MHz that generate waveforms with large amplitude and long period, and ultrasonic transducers of 4.5 MHz, 7 MHz, 10 MHz, and 20 MHz that generate waveforms with relatively small amplitude and short period compared to the above ultrasonic transducers of 0.6 MHz, 1 MHz, 2 MHz, and 2.8 MHz, can be generated alternately, thereby showing excellent effects in treating lesions such as refractory flushing and acne that have been difficult to treat until now. Effects of the invention

[0026] The therapeutic device using multi-frequency ultrasound according to the present invention utilizes a single ultrasonic transducer that alternately emits or selectively emits ultrasound of multiple frequency bands within the range of 0.6 MHz to 20 MHz, rather than an ultrasonic transducer that emits only ultrasound of a single frequency band. Specifically, a high-frequency generating ultrasonic transducer that generates a waveform with a large amplitude and a short period (high frequency band), a low-frequency generating ultrasonic transducer that generates a waveform with a relatively smaller amplitude and longer period than the high-frequency generating ultrasonic transducer (low frequency band), and a medium-frequency generating ultrasonic transducer in the intermediate range can be replaced with a single ultrasonic transducer. Since high-frequency ultrasound, medium-frequency ultrasound, and low-frequency ultrasound can be selectively or alternately generated, skin treatment with optimal ultrasound can be performed using a minimal number of ultrasonic devices without requiring multiple types of ultrasonic therapeutic devices in specialized skin hospitals or skin massage establishments. Consequently, the purchase cost of the ultrasonic therapeutic device can be minimized for individuals, specialized skin hospitals, or skin massage establishments, and costs such as maintenance costs can also be reduced.

[0027] In particular, by selectively generating high-frequency, medium-frequency, and low-frequency ultrasounds alternately or in sequence depending on the lesion, it can have an excellent effect in treating lesions that have been difficult to treat until now, such as intractable rosacea and acne.

[0029] The massager using multi-frequency ultrasound according to the present invention will be described in more detail below with reference to the attached drawings. However, in describing the present invention below, specific descriptions of related known functions or configurations have been omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the present invention.

[0030] Furthermore, the terms described below are defined in consideration of their functions in the present invention, and these may vary depending on the intentions or practices of the user or operator. Therefore, their definitions should be based on the content throughout this specification.

[0031] FIG. 1 is an overall perspective view of the present invention, FIG. 2 is an exploded perspective view of the present invention, FIG. 3 is a perspective view of a vibrator of the present invention, and FIG. 4 is a flowchart of the present invention,

[0032] Referring to FIGS. 1 to 3, the following will be explained in detail:

[0033] The handle (2) included in the main body (4) is configured to be long so that the user can hold it in their hand, and a power cable (50) is formed on one side of the handle (2), and an LED (3) is configured inside on one side of the surface of the handle (2).

[0034] The PCB board (60) configured in the above main body (4) is combined with the vibrator part (1) to form the skin disease treatment device using multi-frequency ultrasound according to the present invention.

[0035] The handle (2) is ergonomically formed so that the user can perform the procedure comfortably by holding it tightly in one hand, and a power cable (50) is provided on one side of the handle (2) to supply power to the main body (4).

[0036] Additionally, the other side of the handle (2) has a structure in which a PCB board (60) is attached. The PCB board (60) has an electrode needle (40) with a spring embedded in the center, and has a structure in which the length of the electrode needle (40) is adjusted by the embedded spring when pressure is applied to the electrode needle (40).

[0037] The vibrator (20) included in the vibrator part (1) that is in close contact with the end of the electrode needle (40) is formed in a flat cylindrical shape, and the upper surface of the vibrator part (1) has a flat shape.

[0038] When the user performs a procedure using the main body (4), which is a skin disease treatment device using multi-frequency ultrasound according to the present invention, the user comfortably holds the handle (2) with one hand and performs the procedure by directly placing the flat upper surface of the vibrator part (1) against the affected area of ​​the patient.

[0039] The flat cylindrical vibrator part (1) is equipped with a single integrated vibrator (20) on the inside. The above vibrator (20) is capable of generating multiple frequencies and is configured so that the electrode needle (40) is in direct contact with it, and the electrode needle (40) can generate ultrasound by applying multiple frequencies.

[0040] The above-mentioned integrated vibrator (20) is formed of piezoelectric ceramic, patterned into a disc shape, and configured by coating a terminal surface so that a constant multi-frequency is applied to the lower part where the electrode needle (40) directly contacts.

[0041] As described above, the main body (4), which is configured to include a handle (2), a power cable (50), and a PCB board (60), and the vibrator part (1) are firmly connected to each other. This allows the fixed connection to be easily released to check or repair the defective part if a problem occurs with the PCB board (60) or the vibrator part (1).

[0042] The electrode needle (40) and LED (3) are located on the PCB board (60).

[0043] The above LED (3) is formed on the PCB board (60), and is formed by making a through hole on one side of the outer surface of the handle (2) so that the light emitted from the LED (3) is emitted to the outside of the main body (4).

[0044] The above electrode needle (40) generates a predetermined voltage using electrical energy applied through the power cable (50), and thereby serves to apply a frequency to the vibrator (20) that can generate ultrasonic waves of 0.6 MHz, 1 MHz, 2 MHz, 2.8 MHz, 4.5 MHz, 7 MHz, 10 MHz, and 20 MHz.

[0045] At this time, when the above electrode needle (40) applies a frequency to the vibrator (20), ultrasonic waves with large amplitude and long period of 0.6 MHz, 1 MHz, 2 MHz, and 2.8 MHz, and ultrasonic waves with small amplitude and short period of 4.5 MHz, 7 MHz, 10 MHz, and 20 MHz are generated in multiples.

[0046] Referring to Fig. 4, the following is explained in detail:

[0047] When power is input from the outside, the power supply unit (81) first converts the external AC voltage into DC voltage and supplies the DC voltage to the control unit (82), each ultrasonic switching unit (83), and the ultrasonic output voltage boosting unit (87), thereby driving the system of the main body (4).

[0048] When a signal command programmed in the above control unit (82) is transmitted to the ultrasonic switching unit (83), the ultrasonic switching unit (83) generates a frequency of a range corresponding to each function and transmits it to the ultrasonic output voltage boosting unit (87) to generate a frequency output for each function.

[0049] The ultrasonic output generated as described above is transmitted to the ceramic part (89), and the ceramic part (89) alternately or selectively emits low-frequency ultrasonic, medium-frequency ultrasonic, or high-frequency ultrasonic corresponding to each frequency range.

[0050] The above embodiments in the present invention are merely examples, and the present invention is not limited thereto. Any configuration having substantially the same structure as the technical concept described in the claims of the present invention and achieving the same functional effect is included within the technical scope of the present invention.
