Description

Technical Field

[0001] The present application relates to the technical field of light therapy, and particularly to a transcranial light regulation device. Background Art

[0002] Existing transcranial light regulation devices reduce the high temperature caused by light irradiation by introducing cold air into the accommodation cavity of the headgear for accommodating the patient's head. During use, the temperature in the accommodation cavity needs to be strictly monitored. Excessive temperature or uneven heating and cooling will affect the comfort of the patient during treatment and may even cause thermal injury. In particular, when the transcranial light regulation device is applied to treat Alzheimer's patients, Alzheimer's patients are less sensitive to temperature and pain than healthy people. Before thermal injury is detected, patients may experience greater pain and potentially greater tissue or organ damage. Therefore, when treating Alzheimer's patients with a relatively high light power density, it is particularly necessary to fully consider the characteristics of the patient group's sensitivity to temperature and pain, and provide a relatively comfortable treatment environment that does not cause pain or even thermal injury, which helps to extend the treatment time and thus achieve better treatment effects.

[0003] In the existing design, air holes are provided at corresponding positions on the inner shell of the headgear to cool the patient's head. The temperature measurement sensor for monitoring the temperature in the accommodation cavity is generally arranged at approximately the middle position of the headgear, and the temperature at this position is used to represent the temperature at various places in the accommodation cavity. Moreover, in order to ensure the comfort of the patient's head during treatment and the service life and measurement accuracy of the temperature measurement sensor, the detection point of the temperature measurement sensor is arranged inside the shell to avoid contact between the detection point and the head during treatment. However, the existing cold air transmission path design will result in a large temperature deviation at various places in the accommodation cavity during treatment. The measurement result of this temperature measurement sensor is not accurate enough to provide a relatively reasonable reference for the temperature regulation of the transcranial light regulation device, resulting in potential safety hazards for the device, making it difficult to ensure that the patient is in a comfortable environment during treatment, affecting the compliance of the patient during treatment, and thus affecting the light therapy effect.

It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0030] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0031] An embodiment of this application provides a transcranial light modulation device. As Figure 1 and Figure 2 shown, the transcranial light modulation device includes a head-mounted device 1, a light-emitting component 2, a guiding component 4, and a first temperature sensing component 3. The head-mounted device 1 includes a first housing 11 and a second housing 12 covering the outside of the first housing 11. A cooling channel 13 is formed between the first housing 11 and the second housing 12. The first housing 11 has a first area 111 and a second area 112 arranged from top to bottom. A first spacer cavity 14 is formed between the first area 111 and the object's head. The light-emitting component 2 is disposed on the outside of the first housing 11 and is used to emit transcranial light to the object's head, such as near-infrared light that can penetrate the skull and act on the cerebral cortex. The guiding component 4 is disposed inside the first housing 11. The guiding component 4 has an exhaust port 41 communicating with the cooling channel 13, and the opening of the exhaust port 41 faces the first spacer cavity 14. The first temperature sensing component 3 is disposed on the head-mounted device 1 and corresponds to the first area 111. The detection end 31 of the first temperature sensing component 3 extends into the first spacer cavity 14 to obtain the temperature information inside the first spacer cavity 14.

[0032] The above-mentioned head-mounted device 1 forms a receiving cavity for receiving the object's head, which can be worn on the object's head during light therapy, and the object's head is placed inside the first housing 11. A first spacer cavity 14 is formed between the first area 111 of the first housing 11 and the object's head. It can be understood that the first spacer cavity 14 is part of the receiving cavity.

[0033] Exemplarily, the cold air in the cooling channel 13 can be supplied via the air inlet 16, and the cold air entering the cooling channel 13 via the air inlet 16 is supplied by a cold air manufacturing device, such as a refrigerator, or can also be supplied by other cold air manufacturing devices. The present application does not make specific limitations thereto.

[0034] The above-mentioned cold air manufacturing device can be arranged outside the head-mounted device 1, or can also be arranged on or inside the head-mounted device 1, for example, inside the cooling channel 13. The present application does not make specific limitations thereto. When the cold air manufacturing device is arranged outside the head-mounted device 1, an air inlet 16 can be provided on the second housing 12, and the cold air manufacturing device provides cold air for the cooling channel 13 via the air inlet 16.

[0035] It should be noted that those skilled in the art can design the number, installation position, size, etc. of the air inlet 16 according to actual needs. The present application does not make specific limitations thereto. For example, the air inlet 16 opened on the second housing 12 can be arranged on the upper part of the second housing 12, or can also be arranged on the side of the second housing 12. Also, for example, in some embodiments, a plurality of air inlets 16 can be respectively opened on the upper part and the side of the second housing 12.

[0036] Preferably, as Figure 2 shown, the air inlet 16 is arranged on the upper part of the second housing 12, so that the cold air in the cooling channel 13 can flow from top to bottom by utilizing the property that cold air naturally delivers from top to bottom.

[0037] In some embodiments, a support structure can be provided between the first housing 11 and the second housing 12, so that the first housing 11 and the second housing 12 can maintain a relatively stable positional relationship, avoiding deformation of the first housing 11 and the second housing 12 due to force, and preventing problems that affect the structure of the cooling channel 13, thereby achieving the purpose of ensuring the fluidity of the cold air in the cooling channel 13.

[0038] It should be noted that the "cold air" in the present application means a gas whose temperature is lower than the temperature in the accommodation cavity during transcranial light therapy, and does not limit the temperature of the gas delivered to the accommodation cavity to a specific value or a specific range. Those skilled in the art can understand that as long as the temperature of the gas delivered to the accommodation cavity is lower than the temperature in the accommodation cavity during transcranial light therapy, it can play a certain cooling effect.

[0039] The above-mentioned light-emitting component 2 can be arranged on the first housing 11, or on the second housing 12, or of course on the structural member outside the second housing 12. The present application does not make specific limitations in this regard, as long as the light-emitting component 2 can be stably installed. Preferably, the light-emitting component 2 is arranged outside the second housing 12, so that the heat generated when the light-emitting component 2 works has less influence on the cold air in the cooling channel 13, and will not overly affect the temperature of the cold air, enabling the cold air to better cool the object's head in the first interval cavity 14.

[0040] The exhaust port 41 of the above-mentioned guiding component 4 can be formed independently by the guiding component 4, or formed by the cooperation of the guiding component 4 and other components. For example, it is formed by the cooperation of the guiding component 4 and the first housing 11. The present application does not make specific limitations in this regard, as long as the exhaust port 41 can communicate with the cooling channel 13 to discharge the cold air therein.

[0041] Through the communication between the cooling channel 13 formed between the first housing 11 and the second housing 12 and the exhaust port 41 of the guiding component 4, it can be realized that the cold air is guided to be delivered more downward through the exhaust port 41 of the guiding component 4, and the delivered cold air is provided to the first interval cavity 14 formed between the first region 111 and the object's head.

[0042] Specifically, the above-mentioned second region 112 can be a region that is relatively more likely to come into contact with the object's head than other regions. Compared with the second region 112, the first region 111 is not likely to come into contact with the object's head (it may also come into contact during large movements of the object's head during transcranial light therapy) or is a region that does not come into contact with the object's head.

[0043] In some embodiments, the guiding component 4 can be arranged at a position where it is easy to come into contact with the head. For example, at the junction of the first region 111 and the second region 112, or for another example, arranged at the relatively lower second region 112. When the guiding component 4 is arranged at a position where it is easy to come into contact with the head, the above-mentioned guiding component 4 can be made of a material with good heat conduction performance, and the cold air in the cooling channel 13 can be delivered to the guiding component 4. In this way, the guiding component 4 can also be effectively cooled by the cold air in the cooling channel 13, so as to achieve the purpose of quickly cooling the object's head through the guiding component 4.

[0044] In some embodiments, the above-mentioned exhaust port 41 can be arranged at the junction of the first region 11 and the second region 12, or can also be arranged in the second region 12. The open end of the exhaust port 41 faces the first interval cavity 14, so that the cold air discharged from the exhaust port 41 can directly enter the first interval cavity 14. In some other embodiments, the exhaust port 41 can also directly extend into the first interval cavity 14 to directly cool the first interval cavity 14 through the cold air.

[0045] The relatively upper part in the accommodation cavity (such as the first partition cavity 14 or the part in the first partition cavity 14 relatively close to the top of the head) can be understood as the part far from the head of the object, and the relatively lower part in the accommodation cavity can be understood as the part close to the head of the object. Since the cold air will naturally be delivered downward, for reasons such as less delivered quantity, unreasonable design of the transmission path resulting in a higher temperature of the cold air delivered to the lower part, etc., the temperature of the part of the area close to the head of the object will be higher than that of the part of the area far from the head of the object, and there may be a problem of uneven temperature in the accommodation cavity.

[0046] By transmitting the cold air in the cooling channel 13 through the guiding component 4, the cold air can be guided from bottom to top into the first partition cavity 14, so that the cold air can first blow to the part of the area close to the head of the object, and then blow to the part of the area far from the head of the object, that is, first cool the part of the area close to the head of the object, and then cool the part of the area far from the head of the object, which can make the temperature of the part of the area close to the head of the object and the temperature of the part of the area far from the head of the object balanced, achieving the purpose that the temperature of each area in the accommodation cavity can be evenly distributed. It can be understood that the temperature deviation of each area in the accommodation cavity is within the preset range to achieve a better cooling effect.

[0047] However, when using a higher light power density for treatment, or as the treatment duration increases, the temperature in the accommodation cavity will become higher and higher. Since a large amount of cold air is preferentially guided to the part of the area in the accommodation cavity close to the head of the object, the temperature in the first partition cavity 14 may exceed the expected range. When using the cold air discharged from the exhaust port 41 to further cool the first partition cavity 14, the cold air discharged from the exhaust port 41 is gradually heated during the rising process, and the rising speed will also gradually slow down. There may be high temperature or uneven temperature in the first partition cavity 14. In this case, in order to ensure the safety and comfort of the head of the object during the treatment process, a first temperature sensing component 3 is provided in the relatively upper first area 111 on the first housing 11, and the first temperature sensing component 3 is used to accurately monitor the temperature in the first partition cavity 14, so that the operator can understand the temperature situation in the first partition cavity 14 based on the monitoring result. In this way, it can provide a more reasonable reference for the temperature regulation of the transcranial light modulation device.

[0048] When the temperature value of the temperature information monitored by the above first temperature sensing component 3 exceeds a certain threshold, it indicates that the temperature in the first partition cavity 14 is too high. At this time, there is a risk of thermal damage to the head of the object. The temperature in the first partition cavity 14 can be reduced by increasing the cold air transmission volume of the exhaust port 41 to ensure the comfort of the head of the object. Or, when the temperature in the first partition cavity 14 continues to rise, the head-mounted device 1 can be selected to be removed and the treatment can be stopped to ensure the safety of the object.

[0049] In this application, the guiding component 4 is provided to effectively isolate the object's head from the first housing 11, and the guiding component 4 can guide the cold air to be delivered to the relatively upper region of the head-mounted device 1 to further cool this region. During the upward delivery of the cold air, the temperature of the cold air will gradually rise and the speed will also slow down. High temperature or uneven temperature may occur in the first spacer cavity 14 formed between the relatively upper first region 111 of the first housing 11 and the object's head. The first temperature sensing component 3 is provided at this position, and the detection end of the first temperature sensing component 3 directly extends into the first spacer cavity 14 and is in full contact with the air in the first spacer cavity 14, so as to accurately measure the temperature in the first spacer cavity 14. The temperature measurement result can provide a more reasonable reference for the temperature control of the transcranial light modulation device, reduce the risk of thermal damage to the object's head during treatment, improve the comfort of the object's head, and provide a comfortable environment for the patient during treatment.

[0050] In some embodiments, as Figure 2 shown, at least part of the guiding component 4 is correspondingly arranged with the second region 112. In this way, through the above-mentioned guiding component 4, the second region 112 can be effectively isolated from the object's head, thereby reducing the risk of thermal damage. The above structural design can make the cold air discharged from the exhaust port 41 flow from bottom to top, so that the cold air discharged from the exhaust port 41 can first blow to the region relatively close to the object's head, that is, the region with a higher temperature, to achieve the purpose that the temperatures of the regions in the accommodation cavity can be evenly distributed, achieve a better cooling effect, and improve the comfort of the object during treatment.

[0051] Especially for the scenario of multi-brain region irradiation, such as the corresponding positions of the frontal lobe, temporal lobe and parietal lobe are evenly provided with the light-emitting components 2. When irradiating multiple brain regions with a high power, there may be regions with large temperature differences in the accommodation cavity. For example, the temperature of the region close to the object's head is much higher than that of the region far from the object's head. This will lead to a serious problem of uneven temperature in the accommodation cavity. The temperature of this region will be higher than that of the region far from the object's head, which will affect the comfort of the object during treatment and the light treatment effect. The structural design of this application can better cool the regions in the accommodation cavity during multi-brain region irradiation, so that the cold air can first blow to the partial regions close to the object's head, and then blow to the partial regions far from the object's head, so that the temperatures of the regions in the accommodation cavity can be balanced, better cool the object's head in the multi-brain region irradiation scenario, and improve the comfort of the object in the multi-brain region irradiation scenario.

[0052] The above-mentioned guiding component 4 can be constructed into any shape and structure such as a tubular structure, a plate-like structure, an arc-shaped structure, etc. This application does not limit the specific structural form of the guiding component 4, as long as it can guide the cold air in the cooling channel 13 to be discharged into the first spacer cavity 14 through the exhaust port 41.

[0053] Exemplarily, the above-mentioned guiding member 4 can be configured as a plate-like structure, and the side surface facing the object's head is configured as an arc surface, which is adapted to the outer contour shape of the object's head, so that the guiding member 4 can contact the object's head more and ensure a certain degree of comfort, thereby effectively cooling the object's head through the guiding member 4.

[0054] Exemplarily, the cross-sectional shape of the guiding member 4 can be an L shape. The L-shaped guiding member 4 has a vertical plate and a horizontal plate. The vertical plate is used to form a gap with the first housing 11, and the exhaust port 41 is located at the upper opening of the gap. The horizontal plate is used to connect the guiding member 4 to the first housing 11.

[0055] A light-emitting component 2 can be arranged at the position corresponding to the guiding member 4, and the light-guiding part of the guiding member 4 can also be made of a light-transmitting material, so that the transcranial light emitted by the light-emitting component 2 can irradiate the object's head through the light-guiding part of the guiding member 4.

[0056] In order to enable the transcranial light emitted by the light-emitting component 2 to irradiate the object's head through the housing, those skilled in the art can set the material of part or the whole of each housing according to the installation position of the light-emitting component 2. For example, when the light-emitting component 2 is arranged outside the first housing 11 and inside the second housing 12, the first housing 11 can be made of a light-transmitting material, so that the transcranial light emitted by the light-emitting component 2 can irradiate the object's head through the first housing 11. Another example is that when the light-emitting component 2 is arranged outside the second housing 12, both the first housing 11 and the second housing 12 can be made of a light-transmitting material, so that the transcranial light emitted by the light-emitting component 2 can irradiate the object's head through the first housing 11 and the second housing 12. Another example is that when a light-emitting component 2 is arranged at the position corresponding to the guiding member 4, the light-guiding part of the guiding member 4 can also be made of a light-transmitting material, so that the transcranial light emitted by the light-emitting component 2 can irradiate the object's head through the light-guiding part of the guiding member 4. It can be understood that the parts of the first housing 11, the second housing 12 and the guiding member 4 corresponding to the installation of the light-emitting component 2 can be made of a light-transmitting material, and the parts not corresponding to the installation of the light-emitting component 2 can not be made of a light-transmitting material, or can also be made of a light-transmitting material, as long as the purpose that the transcranial light emitted by the light-emitting component 2 can irradiate the object's head can be achieved. The present application does not make specific limitations on this.

[0057] The size and quantity of the above-mentioned exhaust port 41 can be adjusted according to the demand for cold air in the first spacer cavity 14. For example, in the case where a large amount of cold air is required in the first spacer cavity 14, more cold air can be provided for the first spacer cavity 14 by increasing the quantity of the exhaust ports 41 and enlarging the size of the exhaust ports 41.

[0058] The above exhaust port 41 can be arranged at the junction of the first region 111 and the second region 112, and the opening of the exhaust port 41 faces the first spacer cavity 14, so that the cold air discharged from the exhaust port 41 can directly enter the first spacer cavity 14. In some other embodiments, the exhaust port 41 can also directly extend into the first spacer cavity 14 to directly cool the relatively high-temperature region in the first spacer cavity 14 through the cold air.

[0059] In some embodiments, the first region 111 includes a first sub-region and a second sub-region arranged from top to bottom, and the first temperature sensing component 3 is arranged corresponding to the first sub-region and / or the second sub-region.

[0060] In this way, by arranging the first temperature sensing component 3 corresponding to the first sub-region and / or the second sub-region, the temperature in the first spacer cavity 14 can be more comprehensively and reasonably characterized with a smaller number of first temperature sensing components 3. The temperature measurement result can provide a more reasonable reference for the temperature regulation of the transcranial light modulation device, effectively improving the comfort and safety of the subject when using the head-mounted device 1.

[0061] A plurality of the above first temperature sensing components 3 can be arranged in the first sub-region. For example, the first temperature sensing components 3 are respectively arranged in different directions corresponding to the head to cooperate with monitoring the temperature in the first spacer cavity 14 corresponding to the first sub-region, so as to determine the temperature felt by the subject's head based on this, and thus the comfort of the subject during the treatment process can be accurately judged.

[0062] A plurality of the above first temperature sensing components 3 can be arranged in the second sub-region. Relatively speaking, the second sub-region is closer to the subject's head than the first sub-region, and it is easier to come into contact with the subject's head. The air circulation in this region of the accommodation cavity will also become worse when the subject's head enters. And when there is a first air outlet hole 113 in the first sub-region, the cold air delivered downward by the first air outlet hole 113 in the first sub-region and the cold air delivered upward by the exhaust port 41 can form a convection in the second sub-region. Therefore, the cooling of the second sub-region and its corresponding first spacer cavity region is mainly achieved through the convection of the cold air. To ensure the safety of the subject when using the head-mounted device 1, it is necessary to strictly monitor whether the temperature in the second sub-region and its corresponding first spacer cavity region reaches the expected cooling effect to further improve the comfort and safety of the subject during the treatment process. Specifically, the first temperature sensing components 3 can be respectively arranged on the opposite sides of the second sub-region to monitor the temperature of this region.

[0063] The above-mentioned multiple first temperature sensing components 3 can be respectively arranged in different directions on the first sub-region and / or the second sub-region, or at different heights on the first sub-region and / or the second sub-region. The present application does not make specific limitations in this regard, as long as it can accurately determine the temperature in the first spacer cavity 14 based on the temperature values detected by the multiple first temperature sensing components 3, so as to provide a more accurate and reasonable reference for the temperature regulation of the transcranial light modulation device.

[0064] In some embodiments, as Figure 2 shown, a first air outlet hole 113 is provided on the first sub-region. The first air outlet hole 113 connects the cooling channel 13 and the first spacer cavity 14 to deliver a part of the cold air in the cooling channel 13 to this region; and / or, no air outlet hole is provided on the second sub-region. When no air outlet hole is provided on the second sub-region, more cold air can flow to the guiding component 4 to improve the cooling effect of the guiding component 4 on the first spacer cavity 14.

[0065] In a preferred embodiment, in order to prevent the temperature in the accommodation cavity corresponding to the first sub-region from being too high to achieve the expected cooling effect when using a relatively high light power density for treatment or as the treatment duration increases, a small number of first air outlet holes 113 can be opened on the first sub-region, and a part of the cold air in the cooling channel 13 is delivered to this region through the first air outlet holes 113 to perform low-temperature compensation on this region and ensure the expected cooling effect.

[0066] It can be understood that an air outlet hole can also be opened at the position of the first housing 11 corresponding to the guiding component 4 to realize the connection between the cooling channel 13 and the exhaust port 41. In order to ensure that more cold air is preferentially delivered to the exhaust port 41, the total air outlet area of the first air outlet holes 113 opened on the first sub-region should be much smaller than the total air outlet area of the air outlet holes opened at the position of the first housing 11 corresponding to the guiding component 4.

[0067] Furthermore, when no air outlet hole is provided on the second sub-region, more cold air can flow to the guiding component 4 to improve the cooling effect of the guiding component 4 on the first spacer cavity 14.

[0068] In addition, when a first air outlet hole 113 is provided on the first sub-region and no air outlet hole is provided on the second sub-region, the first air outlet hole 113 provided on the first sub-region can deliver a part of the cold air into the first spacer cavity 14 and flow downward, and another part of the cold air can be delivered more to the guiding component 4 and then delivered into the first spacer cavity 14 and flow upward through the exhaust port 41 of the guiding component 4. The cold air flowing downward and upward can form a convection near the second sub-region to cool the second sub-region.

[0069] The size and quantity of the above-mentioned first air outlet holes 113 can be adjusted according to the demand for cold air in the first interval cavity 14. For example, when more cold air is required in the first interval cavity 14, the cold air transmission speed can be increased by increasing the air output of the first air outlet holes 113, such as increasing the size and quantity of the first air outlet holes 113 to provide more cold air for the first interval cavity 14.

[0070] The quantity of the above-mentioned first air outlet holes 113 can be multiple, and some of the multiple first air outlet holes 113 can be distributed on the first housing 11 along a preset distance, so as to deliver the cold air evenly and quickly into the first interval cavity 14, thereby achieving the purpose of cooling the head of the object. The size of the above-mentioned preset distance can be determined according to actual use requirements, and the present application does not make any limitation thereto.

[0071] In some embodiments, as Figure 2 shown, first temperature sensing components 3 are arranged on both the first sub-region and the second sub-region, and the first temperature sensing components 3 located on the first sub-region and the second sub-region are arranged in a vertically staggered manner.

[0072] In this way, through the first temperature sensing components 3 arranged in a vertically staggered manner on the first sub-region and the second sub-region, the temperature of the first sub-region and the second sub-region can be comprehensively sensed, and then the temperature in the first interval cavity 14 can be comprehensively judged, effectively ensuring the accuracy of temperature monitoring in the first interval cavity 14.

[0073] Exemplarily, two first temperature sensing components 3 can be arranged on the first sub-region, and two first temperature sensing components 3 can also be arranged on the second sub-region. The two first temperature sensing components 3 corresponding to the first sub-region can be distributed on the left and right sides of the object's head and are located at the first horizontal height. The two first temperature sensing components 3 corresponding to the second sub-region can be distributed on the front and back sides of the object's head and are located at the second horizontal height. The first horizontal height is higher than the second horizontal height, so as to comprehensively monitor the temperature information in the first interval cavity 14 through the cooperation of the four first temperature sensing components 3.

[0074] When the first air outlet 113 delivers cold air into the first partition cavity 14, this part of the cold air first reaches the first sub-region and its corresponding partition cavity part, and the cooling effect on the second sub-region will be weakened. The second sub-region is relatively lower and closer to the exhaust port 41 than the first sub-region. The cold air delivered by the exhaust port 41 preferentially reaches the second sub-region and its corresponding partition cavity part. Therefore, the cooling effect of the cold air delivered by the exhaust port 41 on the first sub-region will be weakened. Moreover, when the object's head enters the first housing 11 for light therapy, it will cause the air fluidity in the first partition cavity 14 to become poor, which is likely to cause local temperature rise. Therefore, the first temperature sensing component 3 arranged with the first and second sub-regions offset up and down can more comprehensively represent the temperatures at different positions in the first housing 11 and the accommodation cavity, so as to facilitate temperature regulation and ensure the comfort and safety of the object during use.

[0075] In some embodiments, as Figure 2 and Figure 3 shown, the transcranial light regulation device further includes an installation component 5 for installing the first temperature sensing component 3. The installation component 5 includes a support frame 51 arranged in the first partition cavity 14. A accommodation cavity 52 for accommodating the detection end 31 of the first temperature sensing component 3 is formed by surrounding between the support frame 51 and the first housing 11, and the accommodation cavity 52 is communicated with the first partition cavity 14.

[0076] In this way, the detection end 31 of the first temperature sensing component 3 is arranged in the accommodation cavity 52 formed by surrounding between the support member and the first housing 11, which can enable the detection end 31 to be in full contact with the gas in the first partition cavity 14 to ensure the accuracy of the detected temperature value result. Moreover, the support frame 51 can also prevent the object's head from touching the first temperature sensing component 3 when using the head-mounted device 1, protecting the object's head while avoiding the situation that the first temperature sensing component 3 is damaged due to collision.

[0077] The above-mentioned support frame 51 can have a plurality of legs, and air vents can be formed between adjacent legs. Cold air can pass through the air vents into the first partition cavity 14, and the detection end 31 of the first temperature sensing component 3 can be in direct contact with the air in the first partition cavity 14 through the air vents to ensure the accuracy of the monitoring result. It can be understood that the larger the distance between multiple adjacent legs, the greater the air permeability of the air vent, that is, the less cold air blocked by the support frame 51. Thus, the detection end 31 can better be in direct contact with the air in the first partition cavity 14, and further increase the accuracy of the temperature result monitored by the detection end 31.

[0078] Exemplarily, as Figure 2As shown, the support legs of the support frame 51 shown in the figure are 4. The 4 support legs can form 4 air vents in different directions, so that the cold air can contact the detection end 31 from 4 directions, thereby improving the accuracy of the first temperature sensing component 3 in monitoring the temperature.

[0079] In some embodiments, as Figure 3 shown, the side of the support frame 51 facing away from the first housing 11 is configured as an arc surface. In this way, when the user wears the head-mounted device 1 for treatment, the support frame 51 with the arc surface can prevent hard contact between the head-mounted device 1 and the user's head, improve the fit between the user's head and the support frame 51, and effectively enhance the comfort of the head-mounted device 1.

[0080] In some embodiments, the above support frame 51 may have an arc plate detachably connected to the support legs, and the arc surface is formed on the arc plate. In some embodiments, there may be multiple specifications of the arc plate, and the radian of the arc surface of different specifications of the arc plate can be different to adapt to heads with different head shapes or different positions of the head. For different user heads or different positions of the head, an arc plate suitable for it can be selected and installed on the support legs to further improve the adaptability between the support frame 51 and the user's head.

[0081] In some embodiments, as Figure 3 shown, the head-mounted device 1 further includes a shielding portion 15 disposed in the cooling channel 13. The shielding portion 15 is disposed around the first temperature sensing component 3, so that the cold air in the cooling channel 13 flows around the first temperature sensing component 3.

[0082] In this way, by setting the shielding portion 15, the cold air can flow around the first temperature sensing component 3 at this position, avoiding the problem that the cold air in the cooling channel 13 directly blows on the first temperature sensing component 3, which may affect the measurement accuracy of the first temperature sensing component 3. Specifically, when the first temperature sensing component 3 passes through the cooling channel 13 and extends its detection end 31 into the first spacer cavity 14, since the temperature of the cold air in the cooling channel 13 is generally less than or equal to the temperature of the cold air in the first spacer cavity 14, in order to prevent the first temperature sensing component 3 from contacting the cold air in the cooling channel 13, thereby affecting the accuracy of the first temperature sensing component 3 in monitoring the temperature in the first spacer cavity 14, the shielding portion 15 disposed around the first temperature sensing component 3 can isolate the first temperature sensing component 3 from the cold air in the cooling channel 13, thereby ensuring the accuracy of the temperature monitoring result of the first temperature sensing component 3 in the first spacer cavity 14.

[0083] The above-mentioned shielding part 15 can be arranged around the outer side wall of the first temperature sensing component 3, and one end of the shielding part 15 can be abutted against the outer side wall of the first housing 11, and the other end of the shielding part 15 can be abutted against the inner side wall of the second housing 12, so as to prevent the cold air from blowing towards the first temperature sensing component 3 through the gap between the shielding part 15 and the first housing 11 or through the gap between the shielding part 15 and the second housing 12.

[0084] The above-mentioned shielding part 15 can be integrally formed on the first housing 11 or the second housing 12, or can be detachably connected to the first housing 11 or the second housing 12. The present application does not make specific limitations on the setting method of the shielding part 15.

[0085] In some embodiments, as Figure 3 shown, the mounting assembly 5 further includes a mounting seat 53 arranged in the cooling channel 13, and the first housing 11 is provided with a mounting hole, and the mounting seat 53 is used for sealingly mounting the first temperature sensing component 3 in the mounting hole.

[0086] In this way, the mounting hole provided on the first housing 11 can enable the detection end 31 of the first temperature sensing component 3 to extend into the first spacer cavity 14 to monitor the temperature in the first spacer cavity 14. Moreover, through the mounting seat 53, the first temperature sensing component 3 can be sealingly mounted in the mounting hole to avoid air leakage, so that the cold air in the cooling channel 13 passes through the gap between the shielding part 15 and the first housing 11 and enters the first spacer cavity 14 through the mounting hole, resulting in inaccurate temperature monitored by the first temperature sensing component 3.

[0087] The above-mentioned mounting seat 53 can be circumferentially arranged around the outer side wall of the first temperature sensing component 3, and one end of the mounting seat 53 can be abutted against the mounting hole, and the other end of the mounting seat 53 can be abutted against the inner side wall of the second housing 12, so as to stably mount the first temperature sensing component 3 on the head-mounted device 1 through the mounting seat 53.

[0088] To further improve the sealing performance of the mounting seat 53 and the accuracy of the monitoring result of the first temperature sensing component 3, and ensure that the part of the first temperature sensing component 3 located in the cooling channel 13 can be isolated from the cold air in the cooling channel 13, a sealing member can be provided at the joint between the mounting seat 53 and the first housing 11 to further ensure the sealing performance. The above-mentioned sealing member can be made of a non-thermal conductive adhesive sealing material to prevent affecting the temperature measurement result of the first temperature sensing component 3, or can be made of other materials. The present application does not make any limitations in this regard.

[0089] In some embodiments, as Figure 3 shown, the first housing 11 is provided with a second air outlet hole 114, the second air outlet hole 114 is arranged close to the first temperature sensing component 3 and is located on the side of the first temperature sensing component 3 close to the exhaust port 41.

[0090] Thus, when the cold air flow delivered by the first air outlet hole 113 passes through the support frame 51, the area below the first temperature sensing component 3 is blocked by the support frame 51, which easily causes the detection surface of the detection end of the first temperature sensing component 3 to be in insufficient contact with the cold air in the accommodation cavity in this area, resulting in inaccurate measured temperature values, and further leading to inaccurate determination of the temperature in the first spacer cavity 14. By providing the second air outlet hole 114, the cold air in the cooling channel 13 can be delivered to the area below the first temperature sensing component 3 to ensure the balance of the temperature in the circumferential direction of the first temperature sensing component 3, and further ensure the accuracy of the monitoring by the first temperature sensing component 3.

[0091] The number and size of the above-mentioned second air outlet holes 114 can be determined according to the position of the area blocked by the support frame 51, and the present application does not make any limitation in this regard. To ensure the balance of the temperature in the circumferential direction of the first temperature sensing component 3, it can be achieved by adjusting the number and size of the second air outlet holes 114. Preferably, in order to avoid the cold air volume delivered by the second air outlet hole 114 affecting the cold air volume delivered by the exhaust port 41 to the first spacer cavity 14, and to ensure the accuracy of the measurement by the first temperature sensing component 3, the cold air volume delivered via the second air outlet hole 114 should be less. For example, in the case where the first air outlet hole 113 is provided in the first sub-region, the total air outlet area of the second air outlet holes 114 should be much smaller than the total air outlet area of the first air outlet holes 113 provided in the first sub-region. In the case where the first air outlet hole 113 is not provided in the first sub-region, the total air outlet area of the second air outlet holes 114 should be much smaller than the total air outlet area of the first air outlet holes 113 provided on the first housing 11 corresponding to the guiding component 4.

[0092] In some embodiments, the transcranial light modulation device further includes a second temperature sensing component (not shown in the figure). The second temperature sensing component is provided on the side surface of the guiding component 4 facing the first housing 11, and the detection end of the second temperature sensing component is in contact with the guiding component 4 to obtain the temperature information of the guiding component 4.

[0093] In this way, the temperature of the guiding component 4 in contact with the subject's head can be accurately monitored by the second temperature sensing component, so that when the temperature of the guiding component 4 is too high, timely intervention can be carried out to avoid thermal damage to the subject's head. Specifically, the first temperature sensing component 3 and the second temperature sensing component are respectively arranged at different positions in the corresponding accommodating cavity. The first temperature sensing component 3 is arranged at a relatively upper position, and the second temperature sensing component is arranged on the guiding component 4, that is, at a position relatively lower than the first temperature sensing component 3. The temperature value measured by the second temperature sensing component also has a certain representativeness for the temperature at this position in the accommodating cavity. On the basis of the first temperature sensing component 3, further using the second temperature sensing component to measure the temperature of the guiding component 4 can achieve temperature monitoring at multiple key positions of concern. The temperature monitoring results can provide a more accurate and reasonable reference for the overall temperature regulation in the accommodating cavity of the transcranial light modulation device, reduce the risk of thermal damage to the subject's head during treatment, improve the comfort of the subject's head, and provide a comfortable environment for the patient during treatment.

[0094] In some embodiments, during the treatment process, when the head swings or the body is fatigued, the above-mentioned guiding component 4 can come into contact with the subject's head. When the contact occurs, the temperatures of the head and the guiding component 4 can be transmitted to the second temperature sensing component. The second temperature sensing component can directly and effectively monitor the temperature of the guiding component 4 and indirectly obtain the temperature of the head. While ensuring the safety of the use of the head-mounted device 1, it also facilitates the operator to regulate the overall temperature in the accommodating cavity of the transcranial light modulation device according to the result. For example, when the temperature value measured by the second temperature sensing component is relatively high, the transmission volume of cold air can be increased or cold air with a lower temperature can be increased.

[0095] The number of the above-mentioned second temperature sensing components can be multiple, and the multiple second temperature sensing components can be arranged in different areas of the guiding component 4 to achieve more comprehensive temperature monitoring.

[0096] In some embodiments, the number of the above-mentioned second temperature sensing components can also be determined according to the number of the guiding components 4. The guiding components 4 can be multiple and the multiple guiding components 4 are arranged at intervals corresponding to the second area 112, and the second temperature sensing components can be arranged in one-to-one correspondence with the guiding components 4.

[0097] In some embodiments, as Figure 1 shown, there are multiple light-emitting components 2. The multiple light-emitting components 2 are respectively arranged corresponding to the first area 111 and the second area 112 of the first housing 11, and the multiple light-emitting components 2 are arranged around the subject's head in cooperation. In this way, the transcranial light can be emitted to the subject's head through the multiple light-emitting components 2 arranged around the subject's head, so as to achieve the purpose of fully treating the subject's head.

[0098] In some embodiments, the transcranial light modulation device is used to treat brain function-related diseases. In particular, it is used to treat at least one of neurodegenerative diseases and mental diseases. For example, Alzheimer's disease (AD), mild cognitive impairment, dementia, etc. It can also be used to treat mental diseases, such as depression, autism, and bipolar disorder, etc.

[0099] It can be understood that during treatment, the irradiation parameters of the transcranial light can be specifically set according to the disease type, degree of illness, etc. This application does not make specific limitations in this regard. Among them, the irradiation parameters can include average power density, pulse frequency, etc.

[0100] In some preferred embodiments, the above-mentioned transcranial light modulation device is used to treat patients with Alzheimer's disease (AD). In addition to showing a decline in cognitive ability, such patients are also accompanied by emotional and mental problems, such as emotional restlessness, anxiety, irritability, insensitivity to temperature, etc. For such patients, a head-mounted device with a loose design (with a certain margin of movement when the head is worn on the head-mounted device) is required, and a relatively high light power density is used to achieve effective treatment. Therefore, when the transcranial light modulation device is used to treat such special patients with Alzheimer's disease (AD), there are high requirements for the temperature and comfort during the treatment process. The solution of this application can achieve a uniform temperature distribution in each area of the accommodation cavity, achieve a better cooling effect, and at the same time, more accurately and comprehensively monitor the temperature of the key area of the first spacer cavity, so as to facilitate timely and reasonable regulation of the overall temperature in the accommodation cavity of the transcranial light modulation device, ensure that the patient's head is in a safe and comfortable treatment environment during treatment, improve the comfort of patients with Alzheimer's disease (AD) during treatment, and enhance the compliance of patients during treatment, which can greatly extend the single treatment duration, and thus can determine a good treatment effect.
