     BACKGROUND ART 
     Low-level lasers (LLLs) are known through various clinical data to cause various effects such as pain relief, blood flow improvement, blood flow enhancement, skin regeneration, cell activation, fat reduction, and cell stimulation depending on a specific wavelength range. Compared to high-level lasers used for the purpose of destruction or intentional damage or necrosis of skin tissue, the low-level laser, which has a wavelength band of 600 nm or more with a relatively low output of 100 mW or less, is relatively safe and has effects of promoting metabolism, revitalizing cells, and increasing immunity and thus has a function of recovering damaged cell tissue. In particular, when the low-level laser having a wavelength band of 800 nm or more is selectively irradiated on acupoints, it is known to have a function of relieving pain in skin or muscle and promoting the healing of an affected region by achieving the same effect as acupuncture or moxibustion treatment.

     Hereinafter, embodiments of a body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions and a body-wearable apparatus set  10  for treating pain by a principle of complex photo-biochemical actions, and a method of controlling the same according to the present invention will be described in detail with reference to the accompanying drawings, and in this case, the same or corresponding elements will be given the same reference numbers regardless of drawing symbols, and redundant descriptions will be omitted. 
     According to the present embodiment, as shown in  FIGS. 1 to 6B , there is provided the body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions, which includes a body portion  110 , in which a plurality of transmission holes are formed so that light is transmitted therethrough, a circuit board  122  disposed inside the body portion  110 , a built-in battery  124  disposed inside the body portion  110 , a first light irradiating portion  111  electrically connected to the circuit board  122  and configured to irradiate light-emitting diode (LED) light through the transmission holes of the body portion  110 , and a second light irradiating portion  113  electrically connected to the circuit board  122  and configured to irradiate low-level laser light through the transmission holes of the body portion  110 , wherein the second light irradiating portion  113  includes a plurality of laser elements that irradiate low-level laser light of different wavelength bands to a treatment site for two or more photo-biochemical reactions, and the photo-biochemical reactions include at least one of cell activation, cell regeneration, cell division, blood flow improvement, vasodilation, cell degradation, and nerve stimulation. 
     Hereinafter, each component of the body-wearable apparatus for treating pain by a principle of complex photo-biochemical actions according to the present embodiment will be described with reference to  FIGS. 1 to 5 . 
     As shown in  FIGS. 2 and 3 , the body portion  110  has a plate shape and may be easily attached to a treatment site. The plurality of transmission holes may be formed in one surface of the body portion  110  so that light is transmitted therethrough. 
     Insertion holes  135  may be formed in the other surface of the body portion  110  so that a band  40  is inserted therethrough. The body portion  110  may be disposed to correspond to the treatment site by inserting the band  40  through the insertion holes  135  and may be stably seated as the band  40  is fixed to a body of a user. 
     In addition, a control button portion  136  through which a power supply and an operation mode may be controlled may be formed on the body portion  110 . 
     As shown in  FIGS. 4 and 5 , the built-in battery  124  may be formed inside the body portion  110 . The built-in battery  124  is charged by a cradle  150  or a charger and may supply power for a light treatment. 
     The body portion  110  may include a battery housing  126  configured to accommodate and protect the built-in battery  124 . The battery housing  126  may include a protrusion on one side thereof. 
     More specifically, the protrusion may form a predetermined clearance to prevent a short circuit that may occur between the circuit board  122  and the built-in battery  124 . 
     Further, the protrusion may press a heating element  132  such that the heating element  132  is pressed against an inner surface of a treatment-performing-surface side of the body portion  110 . Accordingly, heat of the heating element  132  may be more effectively transmitted toward the treatment-performing-surface side of the body portion  110 . 
     Further, since the heating element  132  is located on an end surface of the protrusion, a deterioration phenomenon that may occur when the heating element  132  and the built-in battery  124  come into contact with each other may be prevented. 
     The circuit board  122  may be mounted inside the body portion  110  so as to correspond to positions of the transmission holes. 
     The first light irradiating portion  111  may be electrically connected to the circuit board  122  and irradiate LED light through the transmission holes of the body portion  110 . 
     Further, the second light irradiating portion  113  may be electrically connected to the circuit board  122  to irradiate the LED light through the transmission hole of the body portion  110 . The second light irradiating portion  113  may include first elements  114 , second elements  116 , and a third element  118 . 
     According to the present embodiment, as a light treatment is applied by the body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions, photo-biochemical reactions such as cell activation, cell regeneration, cell division, blood flow improvement, vasodilation, cell degradation, nerve stimulation, pain relief, and blood flow enhancement may occur in the treatment site. 
     The photo-biochemical reactions may occur by irradiating LED light and a low-level laser of a specific wavelength band to the treatment site. 
     In this case, as the first light irradiating portion  110  irradiates light of a blue LED  112  having a wavelength range of 440 nm to 460 nm to the treatment site, pain perceived by the user may be relieved and a natural recovery force may be increased. As an example, the blue LED  112  may include at least one blue LED element having a specific wavelength of 453 nm. A blue LED light source having a wavelength of 453 nm has a critical significance of promoting the generation and circulation of nitric oxide (NO) when it irradiates light to the body as compared to a blue LED light source of other wavelength bands, thereby improving the supply of oxygen and nutrients to muscles and simultaneously reducing pain transmission. Accordingly, the muscles may be relaxed and the pain may be relieved. In particular, the nitric oxide (NO) has been clinically proven to exhibit antioxidant, cell protection, and anti-inflammatory properties, and may protect muscles and nerves from damage and help prevent further injuries. 
     Each of the first elements  114  irradiates a low-level laser having a wavelength range of 630 nm to 680 nm to the treatment site, thereby more effectively relieving pain perceived by the user. As an example, the first element  114  may include a low-level laser element that emits a laser having a wavelength of about 650 nm to 660 nm. The first element  114  described above may amplify the production of ATP cells in mitochondria in a protein cell so that a photo-biochemical principle for replacing damaged cells having a pain-inducing factor is exhibited as an activation principle of normal cell regeneration. 
     Each of the second elements  116  irradiates a low-level laser having a wavelength range of 800 nm to 850 nm to the treatment site, thereby improving blood flow and causing cell regeneration or cell activation of the treatment site. As an example, the second element  116  may include a low-level laser element that emits a laser having a wavelength of 820 nm to 840 nm. The second element  116  causes capillaries to expand to accelerate blood flow, thereby exhibiting an effect of improving blood flow. 
     The third element  118  irradiates a low-level laser having a wavelength range of 900 nm to 990 nm to the treatment site to stimulate nerves in the treatment site, thereby treating pain. As an example, the second element  116  may include a low-level laser element that emits a laser having a wavelength of about 903 nm to 930 nm, which is known to exhibit a pain-relieving effect by a nerve stimulation principle. 
     More specifically, as shown in  FIGS. 3 and 4 , at least two elements of the first element  114  to the third element  118  may operate simultaneously. Since two or more elements simultaneously irradiate low-level lasers to the treatment site to cause complex photo-biochemical reactions, the treatment effect on the treatment site may be increased further. 
     In addition, the second elements  116  and the third element  118  may be arranged in a central region  30  of the body portion  110 , and the first elements  114  and the blue LED  112  may be arranged in a peripheral region  20  of the body portion  110 . 
     In this case, the second elements  116  may be disposed to be spaced apart from both sides of the third element  118 , and the first elements  114  may be arranged to surround the central region  30 , and the LED elements may be arranged in the peripheral region  20  to surround the first elements  114 . 
     By arranging the laser elements in such a structure, the third element  118  is located on a blood vessel of the user to promote or improve the flow of a specific blood flow, and the remaining first elements  114  and the second elements  116  may more effectively treat pain by irradiating light to the treatment site in a relatively large region. 
     Meanwhile, as shown in  FIGS. 3 and 4 , the body portion  110  may further include a heating portion  130  configured to provide thermal energy to the treatment site for thermal treatment, and the heating portion  130  may include a heat sink  134  configured to absorb heat from the second light irradiating portion, the heating element  132  configured to heat the heat sink  134 , a temperature sensor configured to sense a temperature of the heat sink  134 , and a controller configured to control the heating element  132  according to the temperature of the heat sink  134  by detecting a temperature signal from the temperature sensor. 
     The heating portion  130  provides thermal energy to the treatment site to expand a blood vessel of the user, improve blood flow, and promote blood circulation, thereby aiding in pain relief. 
     Here, the heating portion  130  is designed to be heated by the heating element  132  to directly provide thermal energy to the treatment site and may transmit heat generated from the first light irradiating portion  111  and the second light irradiating portion  113  to the heat sink to indirectly transmit additional heat to the treatment site and surrounding portions thereof. 
     As shown in  FIG. 4 , in order to more efficiently transmit heat, the heating element  132  may be designed to be in contact with the heat sink, but the heating element  132  may be designed not to be in contact with the heat sink  134 . 
     In addition, in order to control the operation mode of the light irradiating portion, the body portion  110  may further include a biometric signal detection sensor  120  installed therein and configured to detect a biometric signal of the user. 
     In this case, the biometric signal detection sensor  120  may measure electromyogram, electrocardiogram, ballistocardiogram, seismocardiogram, and photoplethysmogram. It is possible to suggest an optimal treatment method for pain perceived by an individual by detecting the biometric signal of the user and quantifying the pain by the biometric signal detection sensor  120 . 
     In addition, the body portion  110  may include an oscillator  121  therein to apply vibration energy to the treatment site. As the vibration energy is transmitted to the treatment site at the same time as the light treatment, muscles may be relaxed to relieve pain. 
     Hereinafter, a method of controlling the body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions according to the present invention will be described. 
     First, user information including body information and indication may be received from a user through a user terminal (S 110 ). 
     In this case, the body information includes at least one of gender, age, height, and weight, and the indication information may include at least one of a type of indication the user is suffering from, a pain site, and a cause and a symptom of the pain. 
     As described above, since the user information is collected as a database, a server may provide operation mode information optimized to a user&#39;s body condition and state. 
     After the user information is collected from the user, a biometric signal of the user may be detected through a biometric signal detection sensor  120  (S 120 ), and this biometric signal and the user information described above are comprehensively considered so that an operation mode of each of light irradiating portions  111  and  113  may be recommended (S 130 ). 
     In the database of the server, biometric signal data of a normal person may be stored. Accordingly, the server may compare and analyze the detected biometric signal with the normal person&#39;s biometric signal having body information corresponding to the user. That is, the server may compare the user&#39;s biometric signal with a reference range of the normal person to set any one of a plurality of modes as the operation mode, and output the set operation mode to a display of the user terminal. 
     For example, the biometric signal detection sensor  120  may detect a surface electromyogram signal of the user. 
     An electromyogram is a biometric signal in which tension generated in a muscle, which is overworked due to excessive exercise or fatigued due to a chronic disease, is detected as an electrical signal and may represent pain caused by musculoskeletal disorders as accurate and objective numerical values. 
     When voltage or current of the treatment site is detected by the biometric signal detection sensor  120 , the server may calculate an effective value for detecting a representative value of an electromyogram signal frequency. 
     In another example, the biometric signal detection sensor  120  may be attached to the skin to simultaneously measure electrocardiogram, ballistocardiogram, and seismocardiogram. 
     The ballistocardiogram is an electrical record of vibrations according to a heartbeat, which is generated by the rise and fall of blood flow when blood is released into the aorta by the contraction of heart, and represents the momentum of blood ejected by the heart. 
     The electrocardiogram is a recording of an activity current, which is generated in a heart muscle according to the beating of a heart, using an ammeter. 
     The seismocardiogram is a signal reflecting a physical activity of a cardiovascular system according to a blood flow/blood pressure, contraction/relaxation of a heart, and the like rather than an electrical signal of the heart. 
     The server may detect and store the biometric signal using at least one biometric signal detection sensor  120 , analyze the detected signal to extract as a specific point, and calculate cardiovascular parameters using the extracted specific point. 
     More specifically, the server may extract, as the specific point, a point where a slope of the biometric signal is zero and derive at least one of an isovolumic contraction time (ICT), an isovolumic relaxation time (IRT), a left ventricular ejection time (LVET), a pre-ejection period (PEP), and myocardial perfusion imaging (MP 1 ) from the position, interval, amplitude, and frequency of the extracted specific point as the cardiovascular parameters. 
     When the calculation of the cardiovascular parameters is completed, the server may output the cardiovascular parameters to the user terminal. 
     More specifically, the plurality of modes may include first to third modes, and the light irradiating portion may include an LED element configured to emit LED light, and a first element  114 , a second element  116 , and a third element  118 , each of which is configured to emit low-level laser light. 
     When the biometric signal is less than the reference range, the first mode, in which a blue LED  112  and the first element  114  operate, may be set as the operation mode. 
     When the biometric signal corresponds to the reference range, the second mode, in which the first element  114  and the second element  116  operate, may be set as the operation mode. 
     When the biometric signal exceeds the reference range, the third mode, in which the second element  116  and the third element  118  operate, may be set as the operation mode. 
     When the light irradiating portion operates in the second and third modes, a vibrator operates so that vibration energy is provided to the treatment site, and the vibrator may generate the vibration energy, in which at least one of a vibration period and a vibration intensity is different, in the second and third modes. 
     When the operation mode is recommended as described above, the user may put the body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions on the treatment site and operate the body-wearable apparatus  100  by setting the operation mode and a treatment time. 
     Thereafter, when a light treatment is completed, the server may receive a satisfaction index for the light treatment from the user through the user terminal (S 140 ). In this case, the server may confirm a change value of the biometric signal of the user before and after the light treatment by continuously monitoring the biometric signal of the user using the biometric signal detection sensor  120 . 
     Accordingly, the server may analyze the biometric signal of the user and the satisfaction index to calculate a pain relief index (S 150 ). 
     More specifically, the pain relief index may be calculated by adding an addition index according to the biometric signal to the satisfaction index, which is input by the user, when the biometric signal exceeds the reference value, and the pain relief index may be calculated as the satisfaction index itself when the biometric signal is less than or equal to the reference value. 
     When the pain relief index is greater than or equal to the reference index, the server may maintain the operation mode of the light irradiating portion (S 160 ). 
     On the other hand, when the pain relief index is less than the reference index, the server may receive a problem factor from the user and may reset the operation mode of the light irradiating portion according to the problem factor (S 160  and S 170 ). 
     In this case, the problem factor may include at least one of an intensity of the light irradiating portion and the treatment site. 
     When the problem factor is the intensity of the light irradiating portion, the server may reset the operation mode so that at least one of an operation time and an output of the light irradiating portion is increased. 
     When the problem factor is the treatment site of the light irradiating portion, the server may adjust the treatment site of the light irradiating portion according to the user information including at least one of height, weight, age, and gender of the user, thereby resetting the operation mode. 
     More specifically, acupuncture point information of a human body may be stored in the database. The treatment site may be reset as an acupuncture point located at a peripheral portion of a pain portion is reset according to the pain portion that is input to the user information. 
     As described above, when the operation mode of the light irradiating portion is reset according to the problem factor, the reset operation mode is output to the user terminal, thereby providing feedback about the problem factor re-input by the user. 
     On the other hand, a body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions according to another embodiment of the present invention will be described with reference to  FIGS. 8 and 9 . 
     In the case of the body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions according to the present embodiment, there is a difference from the above-described embodiment in that an ultrasonic element is disposed in a central region, and thus, hereinafter, the present embodiment will be described focusing on an ultrasonic element  119  that is different from the above-described embodiment. 
     As shown in  FIG. 8 , a body portion may further include the ultrasonic element  119 . 
     In addition, second elements  116  and the ultrasonic element  119  may be disposed in a central region  30  of the body portion. 
     The ultrasonic element  119  may simultaneously or alternately irradiate a plurality of ultrasonic waves having different frequencies to a treatment site. 
     For example, the ultrasonic element  119  may alternately generate ultrasonic energy of 1 MHz and 3 MHz. For example, the ultrasonic element  119  may irradiate the ultrasonic energy to the treatment site while modulating the frequency at intervals of three seconds. 
     As the ultrasonic element  119  irradiates the ultrasonic energy of a frequency of 1 MHz to the treatment site, it is possible to perform treatment by stimulating a deep muscle at a depth of 1 cm to 5 cm from a treatment-performing-surface, and as the ultrasonic element  119  irradiates the ultrasonic energy of a frequency of 3 MHz to the treatment site, it is possible to perform treatment by stimulating a superficial muscle at a depth of 0.7 cm from the treatment-performing-surface. 
     The ultrasonic element  119  described above may be formed to be thin and small in size so as to be installed inside a small device having a relatively small size. 
     Further, a body-wearable apparatus  100  for treating pain by a principle of complex photo-biochemical actions according to still another embodiment of the present invention will be described with reference to  FIG. 9 . 
     According to the present embodiment, second elements  116 , a third element  118 , and a plurality of ultrasonic elements  119  may be disposed in a central region  30  of a body portion. The ultrasonic elements  119  include a first ultrasonic element  119 a and a second ultrasonic element  119 b, and the first and second ultrasonic elements  119 a and  119 b may irradiate ultrasonic energy of different frequencies. For example, one of the first and second ultrasonic elements  119 a and  119 b may be an ultrasonic element having a frequency of 1 MHz, and the other one may be an ultrasonic element having a frequency of 3 MHz. As another example, the first and second ultrasonic elements  119 a and  119 b may be elements capable of irradiating 1 MHz and/or 3 MHz. In this case, the ultrasonic elements  119  independently control each of the first and second ultrasonic elements  119 a and  119 b to simultaneously emit 1 MHz or 3 MHz to a human body or alternately emit 1 MHz and 3 MHz to the human body. 1 MHz of the first ultrasonic element  119 a is used for treatment of deep muscle located at a depth of about 20 mm to 40 mm from a skin surface, and 3 MHz of the second ultrasonic element  119 b may be used for treatment of superficial muscle located at a depth of about  1  mm from the skin surface. As described above, the ultrasonic element  119  may be provided to enable effective pain treatment by applying ultrasonic energy so as to simultaneously and/or alternately treat the superficial muscle and the deep muscle in a pain region. The ultrasonic elements  119  may be disposed to be spaced apart from both sides of the third element  118  to transmit ultrasonic energy to a large region. 
     As described above, since a low-level laser and ultrasonic energy that are effective in pain relief and blood flow improvement are complexly irradiated on a treatment site, a treatment effect on a pain site may be further increased so that a user may perform continuous pain treatment and reduce treatment costs even when the user does not directly visit a hospital. 
     The embodiments of the present invention have been described above. However, it should be noted that those skilled in the art and understanding the present invention may easily suggest other embodiments by addition, modification, and removal of the components within the same spirit, but these are construed as being included in the spirit of the present invention.
