Description

Near-infrared brain massager

[0001] The present invention relates to a near-infrared brain massager, and more specifically, to a near-infrared light therapy device designed to facilitate blood supply to the brain and prevent and treat brain diseases such as dementia, developmental disorders, depression, and headaches in a non-invasive manner by utilizing the characteristics of near-infrared rays, which raise the body temperature and promote blood circulation, to irradiate near-infrared rays onto major acupoints on the head, such as the Baihui, Taiyang, and Fengchi acupoints. In particular, the invention relates to a near-infrared brain massager designed to maximize the effects of near-infrared rays penetrating the skull by intensively irradiating near-infrared rays onto acupoints in the form of a helmet worn on the head, and to include a structure that allows the wearer to securely fit the helmet to the head size, thereby enabling the near-infrared rays to be effectively delivered to the acupoints and reach the cerebral cortex, thereby maximizing the effects of raising body temperature, promoting blood circulation, and preventing and treating brain diseases.

[0002] The brain is one of the most vital organs in the human body, and impaired blood circulation and metabolic activity can lead to various brain diseases, including dementia, developmental disorders, headaches, and depression. Brain diseases are classified into traumatic events (stroke, traumatic brain injury, etc.), degenerative diseases (dementia, Alzheimer's disease, Parkinson's disease), and mental disorders (depression, anxiety, post-traumatic stress disorder); these conditions are considered major health issues of greatest concern to humanity. According to population projections by Statistics Korea, the domestic population aged 65 and older is expected to reach 9,938,235 in 2024, accounting for 19.2% of the total population. This intensifies the aging of the population, and consequently, the incidence of brain diseases is projected to increase. Against this backdrop, there is a growing need for safe and effective treatment methods.

[0003] Near-infrared radiation has a longer wavelength (800–850 nm) than red light in the spectrum of light emitted from sunlight or heat sources, and it penetrates deeply into the skin and subcutaneous tissue to produce a heat transfer effect. Near-infrared radiation is known to generate bioactive substances such as nitric oxide (NO) and adenosine triphosphate (ATP), which are effective in raising body temperature, improving blood circulation, activating metabolism, relaxing muscles, and relieving fatigue. The National Aeronautics and Space Administration (NASA) mentioned the efficacy of near-infrared radiation in the October 2006 issue of the journal Nature, reporting various health effects such as improved blood circulation, brain function development, muscle relaxation, and fatigue recovery.

[0004] However, due to the high density and low transmittance of the skull, there are limitations to near-infrared rays reaching the cerebral cortex. It has been found that only about 2% to 4% of the near-infrared rays irradiated from the scalp reach the cerebral cortex, with the latter being only 0.9% in the temporal lobe, 2.1% in the frontal lobe, and 11.7% in the occipital lobe. This low transmittance limits therapeutic effects, and if irradiation is performed at high output to compensate for this, there is a risk of low-temperature burns due to overheating of the scalp tissue. Accordingly, existing technologies have proposed methods to bypass the skull or irradiate near-infrared rays through the nasal cavity, but these methods have had limitations in applicability, raising the need for an effective near-infrared delivery method.

[0005] In addition, existing phototherapy methods include low-level laser therapy and photobiomodulation (PBM) using red or near-infrared light. While these are utilized to aid in the healing, regeneration, and protection of damaged tissues, they share a common problem: their effectiveness is limited due to the low penetration of near-infrared light into the skull. More efficient treatment techniques are required to address the issues of reduced near-infrared radiation dose penetrating the skull and skin tissue overheating.

[0006] To solve these problems, the present invention proposes a method of intensively irradiating near-infrared rays onto key acupoints of the head, such as the Baekhoe (crown of the head), Taeyang (temples), and Pungchi (nape of the neck). Since acupoints are located in close proximity to the skull, intensively irradiating near-infrared rays compensates for the problem of reduced skull penetration and enables effective delivery to the cerebral cortex. The Baekhoe acupoint is effective for relieving headaches and dizziness, the Taeyang acupoint for alleviating eye strain and improving migraines, and the Pungchi acupoint for relieving neck and shoulder tension and stress.

[0007] In particular, a helmet-shaped device is used to efficiently deliver near-infrared rays to acupoints, and this invention adopts a structure adjustable to fit the head size to allow the wearer to securely fix the helmet to their head. By designing the helmet to fit snugly against the head, near-infrared rays can be accurately irradiated to the acupoints, preventing a decrease in treatment efficiency caused by shaking or inaccurate positioning. This structure was developed to simultaneously satisfy user convenience and therapeutic efficacy.

[0008] The near-infrared brain massager of the present invention is worn on the head in the form of a helmet to safely and efficiently irradiate near-infrared rays to acupoints. It is designed to prevent low-temperature burns and maximize the preventive and therapeutic effects for brain diseases by including control technology capable of adjusting the amount of near-infrared irradiation. Through this, it provides an innovative technology that enables the non-invasive prevention and treatment of various brain diseases, such as dementia, developmental disorders, headaches, and depression.

[0012] Korean Registered Patent Publication No. 10-1516073

[0013] The present invention was created to address the various problems of the prior art described above. Although near-infrared rays penetrate deeply into the skin and subcutaneous tissue to generate nitric oxide (NO) and adenosine triphosphate (ATP), and have therapeutic effects such as raising body temperature and promoting blood circulation, when passing through bones such as the skull, the penetration rate is only about 2%, which limits the amount reaching the cerebral cortex and thus limits the treatment of brain diseases.

[0014] The present invention aims to provide a near-infrared light therapy device designed to prevent and treat brain diseases such as dementia, developmental disorders, depression, and headaches in a non-invasive manner by utilizing the characteristics of near-infrared rays, which raise human body temperature and facilitate blood circulation, to intensively irradiate near-infrared rays onto key acupoints of the head, such as the Baekhoe point (crown of the head), Taeyang point (temple), and Pungchi point (nape of the neck), thereby compensating for the problem of reduced penetration into the skull and effectively delivering near-infrared rays to the cerebral cortex to facilitate blood circulation.

[0015] In particular, the present invention includes a structure that is worn on the head in the form of a helmet, allowing the wearer to stably adjust the helmet to fit their head size. It is designed to maximize the effect of near-infrared rays penetrating the skull by concentrating near-infrared rays on acupoints, and to ensure that the irradiated near-infrared rays sufficiently reach the cerebral cortex. Furthermore, by utilizing the specific characteristics of the Baihui, Taiyang, and Fengchi acupoints using near-infrared rays, it can alleviate various symptoms such as headaches, migraines, relief of neck and shoulder tension, stress relief, and promotion of eye health, while maximizing the preventive and therapeutic effects for brain diseases.

[0016] Therefore, the purpose of the present invention is to provide an innovative light therapy device capable of preventing and treating various brain diseases, such as early-stage mild cognitive impairment, developmental disorders, depression, and headaches, by exhibiting effects such as raising body temperature, promoting blood circulation, and activating bodily metabolism through the structure and function described above.

[0041] This embodiment is provided to more fully explain the invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize a clearer explanation.

[0042] It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the invention are omitted.

[0044] The near-infrared brain massager (10) of the present invention is developed to prevent the risk of burns caused by strong near-infrared irradiation, as the amount of irradiation decreases and the effect is limited when near-infrared rays pass through the skull. It is intended to effectively deliver near-infrared rays to the cerebral cortex and facilitate blood circulation by irradiating them to acupoints, which are pressure points of the brain.

[0045] Major acupoints located at the cranial junctions are suitable sites for irradiating near-infrared rays to reach the cerebral cortex; representative major acupoints include Fengchi, Taiyang, and Baihui.

[0046] The Fengchi acupoint is located in the nape of the neck, specifically about 4 cm behind both ears, just below the cervical vertebrae where the base of the skull meets the spine. As an important acupoint connecting the head and neck where various muscles, ligaments, blood vessels, and nerves intersect, this point can help alleviate headaches and migraines, relieve neck tension and pain, prevent and treat colds, relieve neck pain and shoulder tension, promote eye health, and relieve stress and tension.

[0047] The Taiyang acupoint is located in the temple area, in the hollow at the back between the eyebrows and the eyes, and is effective in relieving eye fatigue and alleviating migraines or headaches around the eyes.

[0048] The Baekhoe point is an acupoint located at the crown of the head and is known as the point where energy gathers. Stimulating this point is effective for relieving not only headaches but also dizziness and fatigue, and is particularly good for alleviating migraines and tension headaches.

[0049] The near-infrared brain massager (10) of the present invention aims to provide a phototherapy device and control method for the prevention and treatment of brain diseases by irradiating near-infrared rays through a phototherapy module composed of a plurality of near-infrared LEDs to the acupoints described above, thereby allowing near-infrared rays that pass through the skull to reach the cerebral cortex.

[0050] In addition, the near-infrared brain massager (10) of the present invention is characterized by being adjustable to fit snugly against the head regardless of the shape and size of the head of each user, allowing for comfortable wear in a fixed state without shaking, as well as maintaining a stable near-infrared irradiation function for each acupoint.

[0051] To this end, a near-infrared brain massager (10) according to one embodiment of the present invention may be configured to include a headgear (100), a light source module (200), a control unit (not shown), and a head clamping unit (400).

[0052] The headgear (100) is a frame that forms the overall appearance of the present invention and has a shape that is worn on the head in the form of a helmet.

[0053] The headgear (100) is configured to cover major acupoints (pressure points) that are advantageous for near-infrared rays to penetrate the skull and reach the cerebral cortex, and when the headgear (100) is formed to cover the corresponding points, a light source module (200) is positioned inside the headgear (100) to match each acupoint, thereby enabling intensive irradiation of near-infrared rays to the major acupoints.

[0054] Accordingly, the headgear (100) may be configured to include an upper cover (110), a side cover (120), a rear cover (130), a rear inner lining (140), and a side inner lining (150).

[0055] The upper cover (110) is a semicircular frame worn on the crown of the head of the headgear (100), and the crown of the head (111) is formed on the inner side of the upper cover (110) in a portion facing the Baihui acupoint to surround the Baihui acupoint.

[0056] The side cover (120) is connected to the lower part of the upper cover (110) along a circular rim, so the side cover (120) is shaped like a band that wraps around the head in the transverse direction, and a temporal part (121) is formed that is enlarged to a predetermined size in the part facing the temple, and the temporal part (121) is provided to face the solar plexus and surround the solar plexus.

[0057] The rear cover (130) is connected to the rear of the upper cover (110) and the side cover (120) in a plate-like shape with a predetermined width and is provided in a shape that supports the back of the neck corresponding to the nape of the neck, and can be configured in a curved shape so as to be closely attached along the nape of the neck where the back of the head and the neck are connected.

[0058] The rear cover (130) may be configured to face the Fengchi point and may have a rear neck portion (131) that surrounds the Fengchi point.

[0059] The rear inner lining (140) and the side inner lining (150) may be provided according to the curved shape of the headgear (100) so as to be attached to a predetermined position on the inner surface of the headgear (100).

[0060] The rear inner lining (140) can be configured to be in contact with the inner side of the rear cover (130) with a shape corresponding to the rear cover (130).

[0061] The side inner lining (150) has a shape corresponding to the side cover (120), and is composed of multiple pieces formed by cutting and separating the side cover (120) from the front and rear, and the center of each side inner lining (150) is formed in a circular shape corresponding to the temporal part (121), so that when the multiple side inner linings (150) are joined, a shape similar to the side cover (120) can be created.

[0062] A plurality of side inner layers (150) are connected in contact with the rear inner layer (140), and thus the rear inner layer (140) and the side inner layer (150) each function to protect the head while in contact with it on the inside of the rear cover (130) and the side cover (120).

[0063] The light source module (200) functions to irradiate near-infrared rays toward the head and can be installed at at least one point among the upper cover (110), side cover (120), and rear cover (130) along the interior of the headgear (100). As a feature of the present invention, the light source module (200) can be positioned to irradiate near-infrared rays corresponding to at least one acupoint point among the Baihui point, Taiyang point, and Fengchi point.

[0064] The light source module (200) is composed of a near-infrared LED with a wavelength of 800 nm to 850 nm, and can have a light amount capable of irradiating sufficient near-infrared light through acupoints to the inside of the skull.

[0065] In addition, the light source module (200) may include a near-infrared LED with a wavelength of 800 nm to 850 nm and a red LED with a wavelength of 630 nm that helps with the penetration and effect of near-infrared rays, and may also include a blue LED with a wavelength of 405 nm that has a sterilization function.

[0066] Since the light source module (200) needs to transmit near-infrared rays of 25 to 50 mW / cm² to the cerebral cortex, it is desirable to have an irradiation amount not exceeding 500 mW / cm² in order to take into account the near-infrared ray transmittance to human tissues such as skin and to be safe from the risk of low-temperature burns to the human body caused by excessive infrared irradiation.

[0067] Thus, the light source module (200) is configured to face acupoints such as the Baihui point, Taiyang point, and Fengchi point, and therefore, a plurality of light source module (200) can be provided in the crown of the head (111), the temporal part (121), and the posterior neck part (131).

[0068] The light source module (200) may be configured to include a near-infrared LED, a substrate and circuit, a heat sink, a protective cover, etc., and since the device for irradiating near-infrared light is a known technology, the detailed structure will be omitted.

[0069] The control unit may be mounted at a predetermined point of the headgear (100) and configured to control power supply and near-infrared irradiation to the light source module (200).

[0070] The control unit receives power from an external source and is connected to the headgear (100) via a cable to control each light source module (200). The control unit is equipped with a display that allows for the listing, selection, and operation of light source irradiation functions and displays the LED irradiation status. It includes a microprocessor with a built-in control program and may include a constant current driving circuit for stable operation of the near-infrared LED.

[0071] In one embodiment, the control unit is embedded in the headgear (100), and may be provided with a separate control panel equipped with a display connected to the control unit by a cable. Thus, while wearing the headgear (100), the near-infrared irradiation function can be operated using the control panel while viewing the display screen.

[0072] In another embodiment, the control unit may be integrally mounted on one side of the headgear (100), and the headgear (100) may be worn after setting functions such as near-infrared irradiation through an operation panel exposed to the outside of the headgear (100), or it may be wirelessly controlled through a mobile phone application that is wirelessly connected to the control unit of the headgear (100) via short-range communication such as Bluetooth.

[0073] Accordingly, there are no restrictions on the connection method between the control unit and the light source module unit (200).

[0074] The head clamping part (400) is a size adjustment device that allows the headgear (100) to be worn on the head in accordance with the different head sizes of each user.

[0075] The head tightening part (400) may be provided such that a strap (410) is mounted along the inner surface of the headgear (100) and the tightening and loosening of the strap (410) is controlled by a dial (420) configured on the outside.

[0076] In one embodiment, the strap (410) may be configured to be curved and in contact between the rear inner lining (140) and the rear cover (130), and the screw portion of the dial (420) may be connected to the strap (410) while penetrating the rear cover (130). Accordingly, the handle of the dial (420) may be positioned outside the rear cover (130), and the screw portion of the dial (420) may be screw-coupled to the rear cover (130) while penetrating the rear cover (130).

[0077] Therefore, when the dial (420) is rotated in one direction, the screw part that spirals through the rear cover (130) moves spirally toward the head and pushes the strap (410), and accordingly, the strap (410) pushes the rear liner (140) toward the head, and the curved rear liner (140) spreads out along the curve of the back of the head and adheres closely, allowing the entire headgear (100) to fit on the head.

[0078] Conversely, when the dial (420) is rotated in the opposite direction, the curved rear liner (140), which was in a relatively spread-out state to fit the head, is compressed into a curved shape by the restoring force, and as a result, the strap (410) is pushed outward, and the rear liner (140) can be loosely separated from the head.

[0079] The near-infrared brain massager (10) of the present invention allows the wearer to adjust the headgear (100) to fit their head size, thereby maintaining a stable wearing state and consistently irradiating near-infrared rays to acupoints.

[0080] To this end, the head tightening part (400) may be configured with the structure described above, but since the head tightening part (400) is limited to a structure that adheres the strap (410) along the back of the head, there may be limitations in wearing it without shaking while maintaining a state in which the back of the neck (131), as well as the temporal part (121) and the crown of the head (111), are in close contact with the head and positioned in close proximity to the Fengchi, Baihui, and Taiyang acupoints.

[0081] To this end, as an additional embodiment of the present invention, a fit adjustment part (500) may be configured to adjust the headgear (100) to fit the head at other parts including the temples and crown of the head.

[0082] The fit adjustment unit (500) is a device that adjusts the inner side of the headgear (100) so that it fits snugly and is fixed to the head through a predetermined operation after the headgear (100) is worn on the head.

[0083] The fit adjustment part (500) can be mounted through a predetermined point of the headgear (100), and preferably can be formed in a part opposite to the Baihui point, Taiyang point and Fengchi point, so that it can be installed in one or more of the crown of the head (111), the temporal part (121), and the posterior neck part (131).

[0084] In the following description and drawings, the fitting adjustment part (500) is configured in the temporal part (121) as an example, but is not limited thereto and may be installed alone or additionally in other parts including the crown part (111) and the posterior neck part (131).

[0085] The fit adjustment unit (500) may be configured to include an adjustment hole (510), a fit cover (520), a fit adjustment unit (530), a compression spring (540), a compression panel (550), a support pad (560), a fine adjustment hole (570), and a fine adjustment pin (580).

[0086] The adjustment hole (510) can be formed as a through hole of a predetermined size at a predetermined point of the headgear (100) to provide the space necessary for the entire configuration of the fit adjustment part (500) to be installed.

[0087] The adjustment hole (510) can be formed as a circular through hole in the temporal portion (121) as an example, and thus the adjustment hole (510) has a depth equal to the thickness of the headgear (100).

[0088] A fixed end (511) can be formed on one side edge of the adjustment hole (510), that is, on the inner side in the direction in contact with the head, so as to be extended a predetermined length from the edge of the adjustment hole (510) toward the center, thereby enabling the compression panel (550) to be supported by being caught.

[0089] The fit cover (520) is a hemispherical or dome-shaped member that can be mounted to correspond to the outer shape of the adjustment hole (510). When the fit cover (520) is mounted, it becomes a shape that connects to the outer surface of the headgear (100), and can be mounted to cover the other side, i.e., the outer side, of the adjustment hole (510) with a predetermined thickness.

[0090] At this time, the fit cover (520) can be mounted in a shape that covers the outer side of the adjustment hole (510) and rests on the edge of the temporal part (121) including the adjustment hole (510), and the fit cover (520) can be maintained in a fixed state while coupled to the temporal part (121).

[0091] A screw hole (521) with a spiral formed on its surface can be formed in the center of the fit cover (520).

[0092] The fit adjustment unit (530) can be installed through the inside of the fit cover (520) by being inserted and mounted through the screw hole (521), and can be configured to move spirally along the depth of the adjustment hole (510).

[0093] The fit adjustment unit (530) may be configured to include a rotary knob (531), a rotary axis (532), and a push panel (533).

[0094] The rotary knob (531) functions as a rotary handle, and its inner end is configured as a disc shape that is spirally coupled to the inner circumference of the fit cover (520), and its outer end may be shaped to protrude in a cross shape so that it can be held and rotated by hand.

[0095] Accordingly, the rotary knob (531) is coupled to the screw hole (521) of the fit cover (520) and placed in the adjustment hole (510), and has a shape in which the inner end is located inside the screw hole (521) and the outer end protrudes to the outside of the screw hole (521).

[0096] The rotation axis (532) is in the shape of a bar extending inward, that is, in the direction of the head, from the center of one side of the rotation knob (531), and can be formed integrally with the rotation knob (531), so that when the rotation knob (531) is rotated, the rotation axis (532) can be rotated together.

[0097] The push panel (533) is a disc-shaped panel coupled to one end of the rotation axis (532) and is coupled to the inner surface of the adjustment hole (510) so as to be able to slide along the depth direction of the adjustment hole (510).

[0098] That is, the push panel (533) is mounted in the direction inward toward the adjustment hole (510) at a position spaced apart from the fit cover (520) in a manner that blocks the adjustment hole (510), the rotary knob (531) is mounted on the fit cover (520) in a manner that blocks the screw hole (521) of the fit cover (520), and the rotation axis (532) is formed as an axis connecting the fit cover (520) and the push panel (533).

[0099] This shape has a cross-section that is similar to the shape of the uppercase letter I overall, so the top is relatively narrow and the bottom is relatively wide.

[0100] Therefore, when the rotary knob (531) mounted on the fit cover (520) is rotated, the rotation axis (532) rotates, and the push panel (533) coupled to the tip of the rotation axis (532) can slide along with the rotation axis (532).

[0101] At this time, a groove corresponding to the tip of the rotation axis (532) is formed in the center of the other side of the push panel (533), and the rotation axis (532) can be inserted and fixed in the groove of the push panel (533) so that when the rotation axis (532) rotates and moves along the depth direction of the adjustment hole (510), the push panel (533) can also slide along the depth direction of the adjustment hole (510) accordingly.

[0102] That is, the rotary knob (531) and the rotary axis (532) move in a straight line while rotating, but the push panel (533) can move in a straight line without rotation.

[0103] The compression spring (540) is coupled to one side of the fit adjustment unit (530), that is, fixedly coupled in the internal direction of the headgear (100).

[0104] The compression panel (550) is a disc-shaped panel coupled to one side of the compression spring (540), and the outer surface of the compression panel (550) is provided in a state of close contact with the inner surface of the adjustment hole (510) so that it can slide along the depth direction of the adjustment hole (510).

[0105] That is, the compression panel (550) has a shape that slides along the adjustment hole (510) like the push panel (533), and a compression spring (540) having a smaller diameter than the compression panel (550) and the push panel (533) is installed between the compression panel (550) and the push panel (533).

[0106] The pressure panel (550) is in close contact with the inner surface of the adjustment hole (510), but may have a diameter that is smaller than the inner surface of the adjustment hole (510) within a fine range, and thus the pressure panel (550) may be mounted slightly loosely in the adjustment hole (510).

[0107] This is so that, in the case of the push panel (533), it is desirable to move while maintaining a horizontal state in the depth direction of the adjustment hole (510) and to install it in close contact with the inner surface, whereas the compression panel (550) is to be positioned in an inclined state within a fine range rather than a completely horizontal state on the inner surface of the adjustment hole (510), and this is related to the function of the fit adjustment unit (500).

[0108] The outer surface of the pressure panel (550) can be supported by being caught on a fixed end (511) formed on one side edge of the adjustment hole (510), that is, on one side edge of the adjustment hole (510), and thus the pressure panel (550) can be supported so as not to be dislodged from one side edge of the adjustment hole (510) by being caught on the fixed end (511).

[0109] The support pad (560) is coupled to one side of the compression panel (550) and may be formed as a disc-shaped plate of elastic material with a predetermined thickness and a diameter smaller than that of the compression panel (550).

[0110] The support pad (560) is formed such that its outer surface contacts the inner surface of the fixed end (511), and thus the other end of the support pad (560) can be positioned in the depth direction of the adjustment hole (510) while in contact with the pressure panel (550), and one end of the support pad (560) can be exposed to the inside of the headgear (100) by moving away from one side of the adjustment hole (510), so that when worn on the head, the support pad (560) can be in close contact with the wearer's head as if pressing against it.

[0111] Through the structure described above, the fit adjustment unit (500) can adjust the depth of the support pad (560) to fit the head.

[0112] That is, when the outer end handle of the rotary knob (531) is grasped and rotated in one direction, the rotary knob (531) rotates spirally in the screw hole (521) and moves inward toward the adjustment hole (510), and at the same time, the rotation axis (532) moves inward toward the adjustment hole (510) and pushes the push panel (533) inward, and accordingly, the compression spring (540) presses the compression panel (550), and the pressed compression panel (550) pushes the support pad (560) inward toward the headgear (100).

[0113] Therefore, if the headgear (100) is loose because it is larger than the size of the head after wearing the headgear (100), the wearer can hold the rotating knob (531) of the fit adjustment unit (530) at the fit adjustment unit (500) provided on both sides of the headgear (100) and rotate it in one direction to make the support pad (560) fit snugly against the head, thereby allowing the headgear (100) to be adjusted so that it is not loose.

[0114] At this time, the support pad (560) can be made of an elastic material such as a sponge or urethane material, so that it can be deformed and fitted to the shape of the head without impact even when pressure is applied to the head.

[0115] The support pad (560) is pushed outward by a predetermined length in the direction of the adjustment hole (510) while touching the head, so that the compression panel (550) is separated from the fixed end (511) and a predetermined space is formed between the fixed end (511) and the outer surface of the compression panel (550), and the compression spring (540) is compressed between the compression panel (550) and the push panel (533).

[0116] When the fit adjustment unit (530) is moved toward the head and tightened, the support pad (560) is pressed against the head and pushed out in the opposite direction, causing the compression panel (550) and the push panel (533) to exert force in opposite directions, and the compression spring (540) becomes compressed between the opposing panels (550, 533), so that the support pad (560) can maintain a firm contact state with the head, thereby maintaining a stable and unwavering wearing state of the headgear (100).

[0117] If the support pad (560) is pressed too tightly toward the head, it is necessary to move the support pad (560) in the opposite direction to loosen it. In this case, if the rotary knob (531) is rotated in the opposite direction, the push panel (533) moves toward the outside of the adjustment hole (510), and accordingly, the compression spring (540), which was in a compressed state, is extended, and a restoring force acts to push the push panel (533) toward the outside of the adjustment hole (510), thereby allowing the release action to be easily achieved.

[0118] However, the support pad (560) may have a flat side that contacts the head or be configured as a curved shape with a certain curvature, but there may be limitations in perfectly fitting the head of every wearer, whose size and curvature vary.

[0119] That is, while the head generally forms a slope from the temples toward the crown of the head, the support pad (560) is perpendicular to the temples or has a certain curvature, so no matter how much the depth of the support pad (560) is adjusted, there is a limit to the ability to adhere the entire support pad (560) to the sloped head, which varies from person to person.

[0120] Therefore, the fit adjustment unit (500) can adjust the position of the support pad (560) and then adjust the support pad (560) to fit snugly into the sloped shape of the head by operating the fine adjustment hole (570) and the fine adjustment pin (580).

[0121] To this end, the fit adjustment unit (500) may be configured with a fine adjustment hole (570) and a fine adjustment pin (580).

[0122] The fine adjustment hole (570) is a circular through hole that can penetrate the fit cover (520) and the push panel (533) and can be formed at a position spaced a predetermined distance in the direction of the edge relative to the center of the fit cover (520) and the push panel (533).

[0123] At this time, the diameter of the circular shape formed by the fine adjustment hole (570) based on the center of the push panel (533) can be installed to be larger than the diameter of the compression spring (540) coupled to the push panel (533).

[0124] The fine adjustment pin (580) is an operating member configured to be inserted into the fine adjustment hole (570) and to move in a circular motion along the fine adjustment hole (570), and one end may be placed on the outer surface of the fit cover (520), and the other end may be placed between the push panel (533) and the compression panel (550), and may be configured to include a pin head (581) and a pin sphere (582).

[0125] The pin head (581) is formed at the other end of the fine adjustment pin (580), that is, at the outer end of the fit cover (520), and is formed to be exposed to the outside of the fit cover (520). It may be formed in the shape of a sphere or cylinder with a diameter wider than that of the fine adjustment hole (570) so as to be convenient to hold with the hand and not to enter the fine adjustment hole (570).

[0126] The pin sphere (582) is provided at the tip opposite to the pin head (581), that is, at one end of the fine adjustment pin (580), and is configured in a spherical or cylindrical shape with a larger diameter than the fine adjustment hole (570), so that the pin sphere (582) does not fall into the fine adjustment hole (570).

[0127] However, the pin sphere (582) is positioned between the push panel (533) and the compression panel (550), and preferably, it should be installed by taking into account the length and elasticity of the compression spring (540) and the diameter of the pin sphere (582) so that the length of the compression spring (540) and the diameter of the pin sphere (582) are similar when the near-infrared brain massager (10) is not worn.

[0128] The pin sphere (582) is intended to support the area where the pin sphere (582) is located so that when the pressure panel (550) is pushed toward the adjustment hole (510), the pressure panel (550) is not pushed by the fine adjustment pin (580), and only the area where the pin sphere (582) is not located is intended to allow the pressure panel (550) to be pushed by compressing the compression spring (540).

[0129] That is, the pin sphere (582) is intended to provide a function to prevent the pressure panel (550) from being pushed.

[0130] This is because if the pin sphere (582) is smaller than the compression spring (540), it is ineffective in supporting the compression panel (550) when the support pad (560) is pushed, and if the pin sphere (582) is larger than the compression spring (540), it may have a counterproductive effect that restricts the compression panel (550) and the support pad (560) from adhering to the head while adjusting the depth of the push panel (533).

[0131] Therefore, the diameter of the pin sphere (582) is in a range similar to the length of the compression spring (540) in the normal state, but it may be desirable for the distance between the push panel (533) and the compression panel (550) to be slightly larger than the diameter of the pin sphere (582) when the rotary knob (531) is located at the outermost end of the fit cover (520).

[0132] The fine adjustment pin (580) can be rotated and moved in a circular motion along the fine adjustment hole (570). When the wearer wears the near-infrared brain massager (10) and the support pad (560) and the compression panel (550) are pressed outward, the wearer grasps the pin head (581), moves it to a predetermined point, and releases it. In the position where the fine adjustment pin (580) is located, the compression panel (550) is constrained by the pin sphere (582) and does not move outward, whereas in the position where the fine adjustment pin (580) is not located, the compression panel (550) moves outward while compressing the compression spring (540).

[0133] Accordingly, by adjusting the fine adjustment pin (580), the pressure panel (550) is mounted at an angle to a certain extent, deviating from the horizontal state on the inner circumference of the adjustment hole (510), and accordingly, the support pad (560) is also inclined, thereby allowing the inclination of the support pad (560) to be adjusted to match the inclination of the head.

[0134]

[0135] Based on the structure described above, an example of use of the near-infrared brain massager (10) according to a preferred embodiment of the present invention is as follows.

[0136] First, the user can rotate the dial (420) of the head tightening part (400) in the opposite direction to loosen the strap (410) as much as possible so that it does not press against the rear cover (130) and the rear inner lining (140), and then wear the headgear (100) on the head.

[0137] After wearing the headgear (100), the dial (420) is rotated in one direction so that the screw part presses the strap (410), thereby causing the strap (410) to press the rear cover (130) and the rear inner lining (140) toward the head, so that the rear cover (130) is closely fitted to the size of the head, and thus a stable wearing state without shaking can be established.

[0138] When wearing the headgear (100), the crown of the head (111), the temporal region (121), and the posterior neck region (131) are respectively positioned opposite the Baihui, Taiyang, and Fengchi acupoints, and light source modules (200) are concentrated in each of the above regions.

[0139] The user can selectively drive the light source module (200) for each acupoint point through the control unit to irradiate near-infrared light, and can operate the intensity and duration of the near-infrared light, as well as the operation and stop, while viewing the display screen.

[0140] The control unit includes a control circuit that includes a constant current driving circuit capable of adjusting the amount of near-infrared radiation to each acupoint, and may include a function to selectively irradiate near-infrared radiation corresponding to the body temperature and symptoms of patients with different brain diseases, and may also include a function to set the amount of near-infrared radiation in the range of 0 mW / cm² to 500 mW / cm² and to automatically adjust the amount of near-infrared radiation by detecting the body temperature, etc.

[0141] This takes into account the limitations of irradiating the cerebral cortex, which is surrounded by the bones of the skull, with near-infrared radiation. Irradiating near-infrared radiation to acupoints functions to effectively deliver the radiation to brain tissue without damaging skin tissue; therefore, by using the near-infrared therapy device of the present invention, it is possible to prevent and treat brain diseases such as mild cognitive impairment in the early stages of dementia, developmental disorders, and headaches.

[0142] Now, the fit adjustment part (500) can be operated so that the headgear (100) can be worn firmly and comfortably on the head.

[0143] A user wearing the headgear (100) can first adjust the support pad (560) so that it adheres to the head with a certain amount of force.

[0144] To do this, when the rotary knob (531) is grasped and rotated in one direction, the rotary knob (531) rotates inward while being spirally coupled to the screw hole (521), and accordingly, the rotation axis (532) moves inward, causing the push panel (533) to slide.

[0145] As the push panel (533) moves inward toward the headgear (100), force is applied to the compression spring (540), and the compression panel (550) is pushed by the compression spring (540) to push the support pad (560), and the support pad (560) is in close contact with the head. Depending on the degree of close contact with the head, when the user stops rotating the rotary knob (531), the fit adjustment unit (530) remains in a fixed state, and thus the push panel (533) and the compression panel (550) also remain in a fixed state, and the headgear (100) can be maintained in this state fitted to the head.

[0146] However, in this state, only the degree of pressure with which the support pad (560) adheres to the head is adjusted, and since the entire support pad (560) is not optimally fitted to the slope of the head, it is necessary to finely adjust the slope of the support pad (560) according to the shape of the head.

[0147] If the upper side of the support pad (560) is loose and the lower side is tightly fitted in the direction of the ear while the depth of the support pad (560) is adjusted, the user can move the position of the fine adjustment pin (580) to face the upper loose point of the support pad (560).

[0148] That is, by holding the pin head (581) and moving it in a circular motion along the fine adjustment hole (570) until it reaches the upper side of the fine adjustment hole (570), the pin head (581) is released, and the position of the fine adjustment pin (580) can be fixed.

[0149] When the fine adjustment pin (580) moves, the pin sphere (582) is spherical in shape, so it can slide and move smoothly between the compression panel (550) and the push panel (533). The compression spring (540) formed between the compression panel (550) and the push panel (533) has an overall diameter that is smaller than the circular diameter of the fine adjustment hole (570), so it does not restrict the movement of the fine adjustment pin (580). As the pin sphere (582) moves, the compression spring (540) is variably elastically deformed, thereby facilitating smooth movement.

[0150] When the near-infrared brain massager (10) of the present invention is worn on a headgear (100) and attached to the head with a fit adjustment unit (530), the support pad (560) is pressed against the head and pushed outward. However, at the location where the fine adjustment pin (580) is located, the compression panel (550) is blocked by the pin sphere (582) and cannot be pushed outward, so the support pad (560) at the location of the fine adjustment pin (580) also cannot be pushed outward and remains in a state of being strongly attached to the head.

[0151] On the other hand, the direction opposite to where the fine adjustment pin (580) is located, that is, the direction below the fine adjustment hole (570) in this example, near the ear, is the direction furthest from the fine adjustment pin (580), so it is the point where the support force of the pin sphere (582) is weakest, and therefore it is the point where the compression spring (540) can be compressed the most when the support pad (560) is pushed outward.

[0152] Accordingly, the support pad (560) is biased inward toward the head direction at the upper side toward the crown of the head and outward toward the lower side toward the ear, and thus the support pad (560) has a shape that is inclined upward along the head shape.

[0153] This is a shape that can be formed by the user adjusting it to fit a head shape that is relatively wide towards the cheekbones and ears, and relatively narrow towards the crown.

[0154] Users with different head shapes can finely adjust the depth of the support pad (560) by moving the fine adjustment pin (580) in a circular motion along the fine adjustment hole (570) to fit their head shape and then placing it at an appropriate point.

[0155] In the above example, the fine adjustment pin (580) is presented as being composed of only one, but since the head is formed three-dimensionally and there are various shapes for each person, two or more fine adjustment pins (580) can be installed in the fine adjustment hole (570) for fine adjustment.

[0156] In addition, as previously mentioned, the fit adjustment unit (500) can be installed not only at the temporal region (121) but also at the crown region (111) and the posterior neck region (131), and can be installed at multiple other points so as to be adjusted to fit the shape of the head.

[0157] The embodiments of the present invention described above are merely illustrative, and those skilled in the art will readily understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0158] Therefore, it will be well understood that the present invention is not limited only to the forms mentioned in the above detailed description. Accordingly, the true technical scope of protection of the present invention should be determined by the technical concept of the appended claims.

[0159] In addition, the present invention should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
