Description

[0002] With the development of science, research has proved that the treatment of brain dysfunction diseases such as depression, bipolar disorder, Alzheimer's disease (AD), cognitive impairment, etc. by near-infrared light or infrared light is effective.

[0003] When treating brain dysfunction diseases by using a near-infrared light treatment head cap, the patient needs to wear the near-infrared light treatment head cap, and the near-infrared light treatment head cap can emit near-infrared light to irradiate the head of the patient wearing the near-infrared light treatment head cap. In order to improve the treatment effect, the optical power density of the near-infrared light must be sufficient, otherwise it cannot have a good effect on the relevant treatment target area in the head.

[0004] However, the increase of the optical power density will increase the heat accumulation on the scalp or hair (especially for East Asian people with black hair) of the patient, resulting in a serious temperature rise in the head of the patient with brain dysfunction diseases. As the patient's disease progresses, the patient is prone to anxiety, irritability and other problems, such as AD patients or patients with depression, and the overheated head will cause the patient to resist treatment, thereby causing the treatment effect to be poor.

[0026] For keeping the following description of the embodiments of the present application clear and brief, detailed description of known functions and known components is omitted.

[0027] The near-infrared light treatment head cap provided by the embodiments of the present application can be used for treating related brain dysfunction diseases with the relevant parts of the patient's head as the treatment target area, and the brain dysfunction diseases include depression, bipolar disorder, Alzheimer's disease (AD), cognitive impairment, etc. Preferably, the near-infrared light treatment head cap provided by the embodiments of the present application can include but is not limited to a near-infrared light treatment head cap for treating Alzheimer's disease and / or a near-infrared light treatment head cap for treating cognitive impairment.

[0028] As shown in Figure 1 and Figure 2 , the near-infrared light treatment head cap can include an outer shell 210, a middle shell 220 and an inner shell 230. The outer shell 210, the middle shell 220 and the inner shell 230 can be arranged in sequence from outside to inside. The outer side of the middle shell 220 can be provided with a plurality of light irradiation units 100. The middle shell 220 and the inner shell 230 can form a cold air cavity 240 therebetween. The inner shell 230 can inwardly enclose a wearing cavity 250. The inner shell 230 can include a first area 231, a second area 232 and a third area 233. The first area 231 can be located at the top of the inner shell 230, which can correspond to the top area of the object. The second area 232 can be annular and connected immediately below the first area 231. The third area 233 can be curvedly extended downward from the second area 232. The third area 233 can be annular. The third area 233 can be located at the side of the inner shell 230, which can correspond to the side of the object's head. In this way, the second area 232 and the third area 233 can be connected end to end, so as to be used for surrounding the head. The above-mentioned annular shape can be a regular annular shape (such as a circular annular shape, an elliptical shape or a regular polygonal shape), or can be an irregular annular shape.

[0029] Among them, the inner shell 230 can be provided with a plurality of air permeable holes 300. The plurality of air permeable holes 300 can communicate the wearing cavity 250 and the cold air cavity 240. In this way, the cold air can enter the wearing cavity 250 from the air permeable holes 300 via the cold air cavity 240. The air permeable hole arrangement of the first area 231 is different from that of the second area 232 and the third area 233. It should be noted that the air permeable hole arrangement of the first area 231 includes that the first area 231 does not set any air permeable hole, and also includes that the first area 231 sets the air permeable hole 300. The air permeable hole arrangement difference includes but is not limited to the number difference, the arrangement mode difference or the size difference of the air permeable hole.

[0030] In practical application, the head of the subject can be inserted into the wearing cavity 250 through the opening at the bottom of the cavity 250. Then, the near-infrared light emitted by the plurality of light irradiation units 100 can sequentially pass through the light-transmitting middle shell 220 and the inner shell 230 into the wearing cavity 250, so that the head of the subject can be irradiated by the near-infrared light to treat the subject. The irradiation of the near-infrared light can increase the heat accumulation on the scalp or hair of the subject, resulting in an increase in the temperature of the head of the subject. Therefore, the cold air needs to enter the wearing cavity 250 from the air vent 300 through the cold air cavity 240, so as to cool the head of the subject, so that the temperature of the head is within the expected range, thereby improving the comfort of the subject to facilitate the cooperation of the subject in the treatment.

[0031] Exemplarily, in order to reduce the attenuation effect of the hair on the near-infrared light, the subject can generally need to wear a light guide comb before treatment. The light guide comb can generally concentrate the hair at the occipital region. Therefore, the amount of hair at different parts of the head is different, and under the irradiation of the near-infrared light with the same light power density, the temperature of the part with less hair is relatively low, and the temperature of the part with more hair is relatively high. Based on this, by setting the air vent of the first region 231 to be different from the air vent of the second region 232 and the third region 233, different degrees of cooling can be performed on the parts of the head with different temperatures, so that the temperature felt by the whole head is more balanced, the uniformity of the temperature at each position in the wearing cavity 250 during the light treatment process is improved, and the comfort of the subject when wearing the near-infrared light treatment headgear for treatment is improved. In this way, the subject has less resistance to wearing the near-infrared light treatment headgear, thereby facilitating the improvement of the treatment effect.

[0032] Exemplarily, as shown in Figures 1-2 The density of the air vents opened in the first region 231 is less than the density of the air vents opened in the second region 232 and the third region 233. Since the cold air enters the cold air cavity 240 from the top of the head, the temperature of the top region is relatively low, and appropriately reducing the density of the air vents opened in the first region 231 can reduce the amount of cold air passing through the first region 231, so that the temperature felt by the whole head is more balanced, and the comfort of the subject when wearing the near-infrared light treatment headgear for treatment is improved.

[0033] Exemplarily, as shown in Figure 1As shown, the cold air cavity 240 can have an air inlet 241. The air inlet 241 can correspond to the first region 231. Cold air can enter the cold air cavity 240 through the air inlet 241. Since the cold air flows downward, when the cold air enters the cold air cavity 240, if the first region 231 is provided with too many air permeable holes, the cold air can all or mostly enter the wearing cavity 250 through the air permeable holes of the first region 231. This can cause the air permeable holes 300 of the second region 232 and the third region 233 to have no cold air passing through or too little cold air passing through, so as to fail to effectively cool the head corresponding to the second region 232 and the third region 233. Therefore, the air permeable holes of the first region 231 can not need to be provided too much, so that the cold air flows downward under the guidance of the first region 231, and then can pass through the air permeable holes 300 of the second region 232 and the third region 233 in turn to enter the wearing cavity 250. Therefore, when the density of the air permeable holes of the first region 231 is small, the amount of cold air passing through the air permeable holes of the first region 231 is small, so as to ensure that more cold air passes through the air permeable holes 300 of the second region 232 and the third region 233 to enter the wearing cavity 250. In this way, the first region 231 has better guidance to the cold air. Preferably, the first region 231 can not be provided with air permeable holes at all, so as to ensure that all the cold air can pass through the air permeable holes 300 of the second region 232 and the third region 233 to enter the wearing cavity 250. In addition, the above structure can make the cold air flow downward from the top of the head of the object, which is beneficial to improve the heat exchange efficiency in the wearing cavity 250 and make the temperature in the wearing cavity 250 more uniform.

[0034] In other embodiments of the present application, in order to ensure that the air inlet 241 can uniformly transmit cold air to the wearing cavity 250 through the air permeable holes 300 of the cold air cavity 240, the near-infrared light treatment headgear can include a plurality of air inlets 241 distributed at different positions of the cold air cavity 240 to fill cold air into the cold air cavity 240, so as to improve the cooling uniformity of the near-infrared light treatment headgear as a whole. The positions of the air inlets 241 can be designed and adjusted according to the specific structure of the near-infrared light treatment headgear and the arrangement of the light irradiation unit 100.

[0035] Exemplarily, as Figure 1As shown, the air inlet 241 of the cold air chamber 240 is located in the top region and is closer to the front of the inner shell 230 than to the rear of the inner shell 230. The front of the inner shell 230 corresponds to the forehead of the near-infrared light therapy headgear, and the rear of the inner shell 230 corresponds to the back of the head. For example, when using a light guide comb on the upper front and top of the skull, the comb concentrates the hair largely at the occipital region. This hair significantly attenuates the near-infrared light irradiating this area. Therefore, even with increased near-infrared light power density, the treatment effect remains poor, and the temperature at this location is also high. Therefore, in some embodiments, the near-infrared light power density irradiating this area can be appropriately reduced to avoid energy waste. However, since the hair has less influence on the forehead, the near-infrared light power density irradiating this area can be appropriately increased, thereby improving the treatment effect. Therefore, the air inlet 241 can be positioned closer to the front of the inner shell 230 than the rear of the inner shell 230. This makes the distance between the air inlet 241 and the front of the inner shell 230 shorter, allowing more cool air to enter the wearing cavity 250 through the vent 300 at the front of the inner shell 230. This focuses on cooling the forehead area, which can counteract the heating effect caused by the high power density of near-infrared light, prevent local heat accumulation, and ensure uniform cooling throughout the wearing cavity 250.

[0036] For example, such as Figure 1 As shown, the first region 231 can be flat. The third region 233 has a slope of less than a predetermined angle relative to the vertical direction. This results in a relatively small opening at the bottom of the inner shell 230, reducing the amount of cold air leakage through this opening. The second region 232 can form a sloping arc-shaped structure that smoothly connects the first region 231 and the third region 233. The slope of the third region 233 can be less than the slope of the second region 232. The predetermined angle can be largely determined by the slope of the second region 232. With this configuration, the general structure of the inner shell 230 can be adapted to the head of the wearer. Furthermore, cold air can flow relatively smoothly within the cold air chamber 240, facilitating its entry into the wearing cavity 250 through the vent 300.

[0037] For example, such as Figures 1-2As shown, the density of the air vents in the second region 232 can be greater than the density of the air vents in the third region 233. In this way, the air vents 300 in the second region 232 can pass more cold air. Since the object wears the near-infrared light treatment headgear for light treatment, the near-infrared light treatment headgear has different air permeability from top to bottom, the second region 232 is relatively closed, and the third region 233 is closer to the opening at the bottom of the inner shell 230, thereby facilitating air exchange; Therefore, more air vents 300 are arranged at the position corresponding to poor air flow (i.e. the second region 232) to increase the cooling rate, and relatively fewer air vents 300 are arranged at the position corresponding to good air flow (i.e. the third region 233) to facilitate heat dissipation using the external environment, and using the principle of cold air moving down and hot air moving up, thereby achieving the best cooling effect on the head of the object. The arrangement of the air vent unit can balance the temperature from top to bottom as much as possible and increase the comfort during light treatment.

[0038] As shown in FIG. 4, the air vents 300 in the first region 231 can form a first arrangement array 410 and a plurality of first clusters 420. The first clusters 420 are inlaid in the first arrangement array 410. The density of the air vents in each first cluster 420 can be greater than the density of the air vents in the first arrangement array 410. The air vents 300 in the first cluster 420 can be arranged in any shape such as a circle or a snowflake. In this way, more cold air can pass through the air vents 300 in the first cluster 420, thereby cooling the local part of the head. Figures 1-2 As shown in FIG. 4, the air vents 300 in the first region 231 can form a first arrangement array 410 and a plurality of first clusters 420. The first clusters 420 are inlaid in the first arrangement array 410. The density of the air vents in each first cluster 420 can be greater than the density of the air vents in the first arrangement array 410. The air vents 300 in the first cluster 420 can be arranged in any shape such as a circle or a snowflake. In this way, more cold air can pass through the air vents 300 in the first cluster 420, thereby cooling the local part of the head.

[0039] As shown in FIG. 4, the air vents 300 in the first region 231 can form a first arrangement array 410 and a plurality of first clusters 420. The first clusters 420 are inlaid in the first arrangement array 410. The density of the air vents in each first cluster 420 can be greater than the density of the air vents in the first arrangement array 410. The air vents 300 in the first cluster 420 can be arranged in any shape such as a circle or a snowflake. In this way, more cold air can pass through the air vents 300 in the first cluster 420, thereby cooling the local part of the head. Figures 1-2 As shown in FIG. 4, the air vents 300 in the first region 231 can form a first arrangement array 410 and a plurality of first clusters 420. The first clusters 420 are inlaid in the first arrangement array 410. The density of the air vents in each first cluster 420 can be greater than the density of the air vents in the first arrangement array 410. The air vents 300 in the first cluster 420 can be arranged in any shape such as a circle or a snowflake. In this way, more cold air can pass through the air vents 300 in the first cluster 420, thereby cooling the local part of the head.

[0040] As shown in FIG. 4, the air vents 300 in the first region 231 can form a first arrangement array 410 and a plurality of first clusters 420. The first clusters 420 are inlaid in the first arrangement array 410. The density of the air vents in each first cluster 420 can be greater than the density of the air vents in the first arrangement array 410. The air vents 300 in the first cluster 420 can be arranged in any shape such as a circle or a snowflake. In this way, more cold air can pass through the air vents 300 in the first cluster 420, thereby cooling the local part of the head. Figures 1-2As shown, the ventilation holes 300 in the second height range of the second region 232, away from the first region 231, can form multiple second clusters 430. The ventilation holes 300 of the second clusters 430 can be arranged in any shape, such as circular or snowflake-shaped. Each second cluster 430 is opened corresponding to the light irradiation unit (i.e., the second light irradiation unit 120). In this way, the cool air passing through the ventilation holes 300 of the second clusters 430 can cool the part concentratedly irradiated by the second light irradiation unit 120, so that the temperature felt by the entire head is more uniform, and can effectively enhance the breathability of the wearing cavity 250, increase the air heat exchange rate in the wearing cavity 250, and further improve the wearing comfort of the user.

[0041] For example, such as Figures 1-2 As shown, the ventilation holes 300 opened in the third region 233 can form multiple third clusters 440. The ventilation holes 300 of the third clusters 440 can be arranged in any shape, such as circular or snowflake-shaped. Each third cluster 440 can be opened corresponding to a light irradiation unit (i.e., the third light irradiation unit 130). No ventilation holes are opened between adjacent third clusters 440. In this way, the cool air through the ventilation holes 300 of the third clusters 440 can cool down the part concentratedly irradiated by the third light irradiation unit 130, so that the temperature felt by the entire head is more uniform, and it can effectively enhance the breathability of the wearing cavity 250, increase the air heat exchange rate in the wearing cavity 250, and further improve the wearing comfort of the user.

[0042] For example, such as Figures 1-2 As shown, the number of vents in each third cluster 440 is less than the number of vents in each first cluster 420. Since the third cluster 440 is farther from the air inlet 241 than the first cluster 420, but closer to the external environment, the amount of cold air passing through the vents 300 of the third cluster 440 will be less. By reducing the number of vents in the third cluster 440, the limited amount of cold air can be concentrated on the areas with more heat generation, thereby achieving a better cooling effect.
