Description

LED Spot Patch {Light-emitting diode Spot Patch}

The present invention relates to an LED spot patch. In detail, it relates to a patch that is attached to a local area of human skin and can irradiate LED light to the local area.

Light can be used to treat a variety of diseases. When light alone is used to treat disease, the treatment is referred to as phototherapy. Light can be used in conjunction with pharmaceuticals, in which case the treatment is called photodynamic therapy. Phototherapy and photodynamic therapy can be used to treat a variety of skin and internal ailments. In photodynamic therapy, a light-sensitive therapeutic agent, also known as a photopharmaceutical, can be supplied externally or internally to the body part to be treated. The area is then exposed to light of an appropriate frequency and intensity to activate the photopharmaceutical. A variety of photopharmaceutical agents are currently available. For example, there are topical agents such as 5-aminolevulinic acid hydrochloride (Crawford Pharmaceuticals) and methylaminolevulinic acid (Metfix (trademark), Photocure). Often, the drug is applied in a metabolised, non-activated form to a photosensitive photopharmaceutical.

In photodynamic therapy, the main technique for supplying light to a photopharmaceutical is to project light of an appropriate wavelength from a self-actuating light source such as a laser or a filtered arc lamp. These sources are complex and expensive, and are therefore suitable only for use in hospitals. This causes inconvenience to the patient and high cost for treatment. High light radiation is needed to treat an acceptable number of patients per day (for treatment to be cost effective) and to avoid undue discomfort to the patients. Recently, in photodynamic therapy, devices capable of photodynamic therapy using a simple device at home rather than using a professional device have been introduced, and a light emitting device was introduced in Korean Publication No. 10-2011-0110115.

On the other hand, light such as a low-level laser (LLL) or LED has various effects such as pain relief, blood flow improvement, blood flow enhancement, skin regeneration, cell activation, lipolysis, and cell stimulation, depending on a specific wavelength range. It is known through several clinical data that there are effects. In particular, compared to high-power lasers that are used for destruction, intentional damage or necrosis of skin tissue, low-power lasers or LEDs with a relatively low power of 100 mW or less and a wavelength of 600 nm or higher are relatively safe, while promoting metabolism and activating cells. , And it has the effect of increasing immunity, and has the function of restoring damaged cell tissues. In particular, it is known that when selectively irradiating a low-power laser or LED in a wavelength range of 800 nm or higher to acupuncture points, it exerts the same effect as acupuncture or moxibustion treatment, relieving pain in the skin or muscles and promoting healing of the affected area. Regarding Korea Patent Publication No. 10-2019-0044480, a light treatment patch set, Korean Patent Publication No. 2011-0110115, a disposable skin care device, US Patent Publication No. 2011-0257585, Medical apparatus, European Patent Publication No. 3678737 In , a self-adhesive phototherapy treatment device was introduced. However, the patch device according to the prior art has a relatively heavy weight to attach to the skin and has a problem of being separated from the skin without maintaining the attachment to the local area of the skin due to its thick thickness, and the device is attached due to the weight of the device itself. As the affected skin area and the surrounding skin area are pulled in the direction of gravity for a considerable amount of time, there is a problem of sagging skin and feeling discomfort in use. In particular, when the device is attached to an area of the body that is not level with the ground, such as the face, in order to ensure that the device is not separated from the face and is stably positioned, for example, the user must remain lying down, so it is necessary to use the device during normal activities. There are limits to its use. In the prior art, an adhesive sheet or the like is additionally provided for stable attachment of the device or a separate band configuration for fixing the device to the body is considered, but the user's discomfort due to the adhesive substance remaining on the skin after the adhesive sheet is removed, Reluctance to use the adhesive sheet in attaching the adhesive sheet to the sensitive skin area of the face, restriction of the body area where the device is attached due to wearing the band, and discomfort in wearing due to the band are major obstacles for actual users to easily use the device. has become In addition, European Patent Publication No. 3678737 adds a flexible band to the device so that the device can be well attached to the skin, but there is a problem in that marks of the band remain on the skin for a certain period of time after removal of the device. That is, the prior art has limitations in not overcoming the inconvenience of use in terms of the weight and size of the device. The light emitting device of Korean Patent Publication No. 2011-0110115 does not have a housing in appearance, so the size and weight of the device can be reduced with a plurality of LED devices on a flexible substrate, but power is received by wire to drive a plurality of LEDs, so that the device Connection of the power cable is required. Such a power cable limits the activity radius of the user while the device is attached and places many restrictions on comfortable use of the device. In addition, Korea Patent Publication No. 2012-0115765, an adhesive patch for menstrual pain treatment, Korean Patent No. 1225133, a menstrual pain treatment device, Korean Patent No. 1339402, a color light therapy device, Korean Patent No. 1642836, a disposable light electrode for a low-power light therapy device, published in Korea Patent No. 2020-0031830 myocardial and cardiovascular relaxation device, Korean Patent Publication No. 2246714, skin drug delivery and cosmetic active patch using photoreactive microcurrent, Japanese Patent Registration No. 3203644 phototherapy device, Korean Patent Publication No. 2018-0045118 Patch-type health care device, Korean Patent No. 1497020 patch-type electromagnetic wave therapy device, Korean Patent No. 1664152, skin-attachable light-emitting diode patch assembly equipped with an insoluble hydrogel layer for maintaining irradiation intensity, Korean Patent Publication No. 2015-0135618 treatment Alternatively, various patch technologies such as a light emitting module for cosmetic use have been introduced, but many limitations of the conventional technology have not been overcome in minimizing the weight and miniaturization of the device.

In addition, in order to reduce the size and weight of the device, it is required to reduce the complexity of the circuit and implement various functions in a simple manner. In relation to this, a phototherapy device of Japanese Registered Patent No. 3203644, which attempted to remove the power switch, was introduced, but instead of a switch, a complex mechanism called a power supply unit, which has a feature of determining the electrical connection of the battery according to rotation, was introduced, and the weight of the device was introduced. There are still limits to reducing and minimizing the size. In addition, the technology introduced in Korean Patent No. 1497020 patch-type electromagnetic wave therapy device and Korean Patent No. 1664152, a skin-attachable light emitting diode patch assembly equipped with an insoluble hydrogel layer for maintaining irradiation intensity, is an insulation that releases non-contact between power and terminals. Although it has a feature of using a sheet configuration, there is a limit to the miniaturization of the device and a decrease in the yield of the device in that a spare space for the insulation sheet to be located between the battery and the terminal must be separately provided in the device. In addition, the light emitting module for treatment or cosmetic use of Korean Patent Publication No. 2015-0135618 has a feature of automatically turning on the power of a device using a phototransistor, but the complexity of the circuit increases to implement the phototransistor and a circuit reacting to it. Limitations such as an increase in the thickness and weight of the device are pointed out.
