Description

A transcranial light modulation device

[0001] This application claims priority to Chinese patent applications 202411200988.6, 202411200996.0, 202411200991.8 and 202411200999.4, filed on August 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of transcranial light modulation technology, and more particularly to a transcranial light modulation device. Background Technology

[0003] Existing transcranial phototherapy devices reduce the high temperatures caused by phototherapy by introducing cool air into the cavity of the headpiece used to accommodate the patient's head. For example, in the existing design CN115212468A, air vents are set at various positions on the inner shell of the headpiece corresponding to different head locations. Cool air is blown directly onto the patient's head through these vents, thereby cooling the head. Currently, due to the characteristics of patients' symptoms and the long duration of phototherapy, patients' heads often press against the inner shell during phototherapy. This contact blocks the air vents at those positions, making it difficult for cool air to be delivered to the cavity. This causes the area to heat up rapidly, resulting in patient discomfort.

[0004] Some existing solutions, such as CN219662665U, use a diaphragm inside the cap to prevent the patient's head from pressing against the inner wall. However, the diaphragm's blocking effect is limited, and the vents may still be blocked by hair, leading to excessively high local temperatures, poor heat dissipation, and potential heat damage to the head. This can affect the patient's comfort during treatment and thus the treatment outcome. Summary of the Invention

[0005] To address the aforementioned technical problems in the existing technology, this application provides a transcranial light modulation device that can directly blow cold air onto a support component located in a second area that is prone to contact with the subject's head. By cooling the support component, the device can cool the subject's head when it is in contact with the support component, thereby improving the safety and comfort of the subject's head during light therapy.

[0006] This application provides a transcranial light modulation device. The transcranial light modulation device includes a head-mounted device, a light irradiation unit, and a support member. The head-mounted device has a receiving cavity for accommodating a subject's head and includes a first housing and a second housing disposed outside the first housing. A cold air transmission cavity is formed between the first and second housings. The first housing has a first region and a second region below the first region. The light irradiation unit is disposed outside the first housing and is used to emit transcranial light towards the subject's head. The support member is disposed inside the first housing corresponding to the second region and forms a spacer cavity between it and the first housing. The first housing has a first air outlet communicating with the cold air transmission cavity, and at least a portion of the first air outlet is disposed corresponding to the support member.

[0007] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: By placing the support member in a relatively lower second region of the first housing that is easy to come into contact with the object's head, the first housing and part of the object's head are separated, preventing the object's head from directly abutting against the inner side of the first housing and blocking the first air outlet on the first housing, thereby ensuring the flow of cold air. Furthermore, the first air outlet on the first housing can deliver the cold air in the cold air transmission chamber to the spacer formed between the support member and the first housing, thus allowing the cold air to be directly blown onto the support member. The cold air can lower the temperature of the support member, effectively cooling it. Even if the object's head comes into contact with the support member, the temperature of the area where the object's head and the support member are in contact can be reduced, thereby effectively cooling the object's head and preventing the object's head from overheating during phototherapy, reducing the risk of thermal damage, and improving the safety and comfort of the object's head during phototherapy.

The embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific examples, but these are not intended to limit the scope of this application.

When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may not be directly connected to the other devices but may have an intermediary device.

[0028] All terms used in this application (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] This application provides a transcranial light modulation device. As shown in Figures 1 to 4, the transcranial light modulation device includes a head-mounted device, a light irradiation unit 4, and a support member 5. The head-mounted device has a receiving cavity 17 for accommodating a subject's head and includes a first housing 1 and a second housing 2 disposed outside the first housing 1. A cold air transmission cavity 3 is formed between the first housing 1 and the second housing 2. The first housing 1 has a first region 11 and a second region 12 below the first region 11. The light irradiation unit 4 is disposed outside the first housing 1 and is used to emit transcranial light, such as near-infrared light capable of penetrating the skull and acting on the cerebral cortex, towards the subject's head. The support member 5 is disposed inside the first housing 1 corresponding to the second region 12 and forms a spacer cavity 51 between it and the first housing 1. The first housing 1 has a first air outlet 13 communicating with the cold air transmission cavity 3, and at least a portion of the first air outlet 13 is disposed corresponding to the support member 5.

[0031] The aforementioned head-mounted device can be worn on the head of the subject during phototherapy, with the subject's head positioned inside the first housing 1. When wearing the head-mounted device, if the subject's head moves left and right, back and forth, or if the body becomes fatigued within the receiving cavity 17, a portion of the head can easily come into contact with the inner wall of the first housing 1, and in particular, it can easily come into contact with the second region 12 below the first region 11.

[0032] Specifically, the first region 11 of the first shell 1 is positioned higher than the second region 12. This can be understood as the first region 11 being a region that is less likely to come into contact with the subject's head, or even not at all, relative to the second region 12. However, during phototherapy, if the subject's head makes significant movements, the first region 11 may come into contact with the subject's head. As shown in Figure 3, the second region 12, located below the first region 11, can be understood as a region that can come into contact with the subject's head, or as a region that is relatively easier to come into contact with the subject's head compared to other regions. For example, when the subject is fatigued during phototherapy, their head often comes into contact with the second region 12 of the first shell 1.

[0033] The support member 5 is positioned relative to the lower second region 12 of the first housing 1, which is more likely to come into contact with the subject's head. This separates the subject's head from the first housing 1. Thus, during phototherapy, when the subject's head comes into contact with the second region 12 of the first housing 1, the head will not directly contact the inner wall of the first housing 1, but will instead contact the support member 5. If the temperature of the support member 5 is too high, this excessive heat can be transferred to a portion of the subject's head, potentially causing thermal damage. Furthermore, when the head is close to or even in contact with the support member 5, the gap between them decreases or may even disappear, resulting in poor heat dissipation for that area. As the phototherapy duration increases, the temperature in that area will rise further. If black or gray hair is present in that area, it will further accumulate heat, leading to excessively high local temperatures and potentially causing thermal damage.

[0034] A first air outlet 13 communicating with the cold air transmission chamber 3 is formed on the first housing 1, and at least a portion of the first air outlet 13 is disposed corresponding to the support member 5. This allows the cold air in the cold air transmission chamber 3 to be blown onto the support member 5 through the first air outlet 13 to reduce the temperature of the support member 5. Thus, when the head is in contact with the support member 5, the area where the head is in contact with the support member 5 can be effectively cooled, ensuring a cooling effect on the head and preventing heat damage. Furthermore, since the support member 5 separates the head from the first housing 1, the head and hair will not block the first air outlet 13 on the first housing 1, and will not obstruct the transmission of cold air into the partition chamber 51, thus affecting the cooling effect on the support member 5. In this way, a continuous cooling effect on the head can be ensured during phototherapy.

[0035] It is understood that the cold air in the cold air transmission cavity 3 can be supplied by a cold air supply device, such as a refrigerator, or by other cold air generating devices, such as a fan. Specifically, the cold air supply device can be located outside the head-mounted device, or on or inside the head-mounted device, for example, in the cold air transmission cavity 3. This application does not specifically limit the source of the cold air supply or the location of the cold air supply device, as long as there is cold air in the cold air transmission cavity 3 that can be delivered to the support member 5.

[0036] For example, when the air supply device is located outside the head-mounted device, the second housing 2 may be provided with an air inlet 21, through which the air supply device provides air to the air transmission chamber 3.

[0037] It should be noted that the term "cold air" in this application refers to gas with a temperature lower than that in the receiving cavity 17 during transcranial phototherapy. It does not limit the temperature of the gas in the cold air transmission cavity 3 to a specific value or range. Those skilled in the art will understand that as long as the temperature of the delivered gas is lower than that in the receiving cavity 17 during transcranial phototherapy, it can achieve a certain cooling effect.

[0038] It should be noted that the light irradiation unit 4 can be disposed on the first housing 1, the second housing 2, or inside the cold air transmission cavity 3. It can also be disposed on a structural component outside the second housing 2 (as shown in Figure 1). This application does not impose specific limitations on this, as long as the light irradiation unit 4 can be stably installed on the transcranial light control device to emit transcranial light for treatment onto the subject's head. Preferably, the light irradiation unit 4 is disposed on the outside of the second housing 2, with the second housing 2 separating the light irradiation unit 4 from the cold air transmission cavity 3. This minimizes the impact of the heat generated by the light irradiation unit 4 on the cold air inside the cold air transmission cavity 3, preventing excessive influence on the temperature of the cold air and allowing the cold air to better cool the subject's head in the receiving cavity 17.

[0039] To allow the transcranial light emitted by the light irradiation unit 4 to pass through the housing and illuminate the subject's head, those skilled in the art can customize the material of parts or the entire housing based on the placement of the light irradiation unit 4. For example, when the light irradiation unit 4 is located outside the first housing 1 and inside the second housing 2, the first housing 1 can be made of a light-transmitting material, allowing the transcranial light emitted by the light irradiation unit 4 to pass through the first housing 1 and illuminate the subject's head. Similarly, when the light irradiation unit 4 is located outside the second housing 2, both the first housing 1 and the second housing 2 can be made of a light-transmitting material, allowing the transcranial light emitted by the light irradiation unit 4 to pass through both the first housing 1 and the second housing 2 and illuminate the subject's head. Furthermore, when the light irradiation unit 4 is positioned corresponding to the support member 5, the light-guiding portion of the support member 5 can also be made of a light-transmitting material, allowing the transcranial light emitted by the light irradiation unit 4 to pass through the light-guiding portion of the support member 5 and illuminate the subject's head. It is understood that the parts of the first housing 1, the second housing 2 and the support member 5 that correspond to the light irradiation unit 4 can be made of light-transmitting material, while the parts that do not correspond to the light irradiation unit 4 can be made of light-transmitting material or not, as long as the purpose of the transcranial light emitted by the light irradiation unit 4 can be irradiated onto the head of the object is achieved. This application does not make any specific limitations in this regard.

[0040] The support member 5 can be made of a material with good thermal conductivity so that the cold air in the partition cavity 51 can effectively cool the support member 5, thereby achieving the purpose of rapidly cooling the head of the object through the support member 5.

[0041] In some embodiments, the support member 5 can be constructed as a tubular structure, a plate structure, an arc structure, or any other shape. This application does not limit the specific structural form of the support member 5, as long as it can ensure the comfort of the object's head when it is against the support.

[0042] In some embodiments, as shown in Figures 5 to 7, the support member 5 can be constructed as a plate-like structure, a wavy arc-shaped structure, or a plurality of spaced-apart plate structures. Specifically, the support member 5 shown in Figure 5 is constructed as a plate-like structure, the support member 5 shown in Figure 6 is constructed as a plurality of spaced-apart plate structures, and the support member 5 shown in Figure 7 is constructed as a wavy arc-shaped structure. Preferably, the side of the support member 5 facing the object's head can be constructed as an arc-shaped surface, which adapts to the outer contour shape of the object's head, allowing the support member 5 to comfortably contact the object's head and increasing the contact area, thereby providing comfortable and effective cooling for the object's head through the support member 5.

[0043] The size and number of the first air outlet 13 can be adjusted according to the amount of cold air required to achieve the preset cooling effect. For example, if a large amount of cold air is required in the partition cavity 51, the cold air can be guided to be transmitted downward by increasing the air volume of the first air outlet 13 at the corresponding partition cavity 51, such as by increasing the size and / or number of the first air outlet 13 to provide more cold air to the partition cavity 51.

[0044] For example, there can be multiple first air outlets 13, and some of the multiple first air outlets 13 can be distributed along a preset distance on the first housing 1 to deliver cold air evenly and quickly into the partition cavity 51, thereby cooling the support member 5 and the head of the object in contact with the support member 5. Of course, in some embodiments, in addition to being provided with the partition cavity 51, the first air outlets 13 can also be provided with the receiving cavity 17, so that some of the cold air discharged from the first air outlets 13 can be blown towards the head of the object from other positions, thereby achieving the purpose of cooling the head of the object. The size of the preset distance can be determined according to actual usage requirements, and this application does not impose any limitations.

[0045] In some embodiments, the second region 12 may be an annular region that can circumferentially abut against the head of the object. A support member 5 is provided on the second region 12, which can separate the head of the object from the first housing 1 in the circumferential direction. The head of the object can be cooled by the support member 5, which is cooled by cold air, at any position where the head of the object abuts against the support member 5 in the circumferential direction.

[0046] In some embodiments, as shown in FIG3, the upper region of the receiving cavity 17 formed between the first region 11 and the object's head can communicate with the spacer cavity 51, so that the cold air in the spacer cavity 51 can also enter the upper region of the receiving cavity 17, thereby cooling the upper region of the receiving cavity 17. It is understood that the upper region of the receiving cavity 17 is a part of the receiving cavity 17 formed by the head-mounted device to receive the object's head.

[0047] In this way, the cold air is first delivered from the cold air transmission chamber 3 to the partition chamber 51 and cooled down the support member 5. Then, it can be delivered to the upper region of the receiving chamber 17 through the partition chamber 51. This ensures that the support member 5 cools down the head of the patient while further reducing the temperature of the upper region of the receiving chamber 17, achieving a uniform cooling effect throughout the receiving chamber 17. This keeps the temperature value of each part of the receiving chamber 17 within a preset range, thereby further ensuring the comfort and safety of the patient during the treatment process. In particular, when the first air outlet 13 is not opened in the first region 11, or only a very small number of the first air outlet 13 are opened, and the cold air is first guided to be delivered downward from the upper part of the cold air transmission chamber 3 to the spacer chamber 51, during the treatment process, when the head-mounted device is worn on the subject's head, the airflow in the upper region of the receiving chamber 17 formed between the first region 11 and the subject's head will slow down. As the treatment time increases, the heat generated during the treatment process will also increase. When the first air outlet 13 is not opened in the first region 11 or only a very small number of the first air outlet 13 are opened, the temperature in the upper region of the receiving chamber 17 will rise, and it may not be possible to achieve good heat dissipation. Delivering some of the cold air in the spacer chamber 51 to the upper region of the receiving chamber 17 can further achieve a good heat dissipation effect on the upper region of the receiving chamber 17, and further ensure the comfort and safety of the subject during the treatment process.

[0048] In some embodiments, the first housing 1 may be a one-piece molded structure or may be formed by connecting multiple different structures. The second housing 2 may also be a one-piece molded structure or may be formed by connecting multiple different structures. As long as the overall structural stability of the first housing 1 and the second housing 2 can be guaranteed, and a cold air transmission cavity 3 can be formed between the first housing 1 and the second housing 2, this application does not specifically limit the specific structure of the first housing 1 and the second housing 2.

[0049] This application separates the first housing 1 and part of the object's head by placing the support member 5 in the lower second region 12 of the first housing 1, which is more likely to come into contact with the object's head. This prevents the object's head from directly contacting the inner side of the first housing 1 and blocking the first air outlet 13 on the first housing 1, thus ensuring the flow of cold air. Furthermore, the first air outlet 13 on the first housing 1 can deliver the cold air in the cold air transmission chamber 3 to the spacer 51 formed between the support member 5 and the first housing 1, allowing the cold air to be directly blown onto the support member 5. The cold air can lower the temperature of the support member 5, effectively cooling it. Even if the object's head comes into contact with the support member 5, the temperature of the area where the object's head and the support member 5 are in contact can be reduced. This effectively cools the object's head, preventing it from overheating during phototherapy, reducing the risk of thermal damage, and improving the safety and comfort of the object's head during phototherapy.

[0050] In some embodiments, at least a portion of the support member 5 is configured as an arc-shaped plate or an annular plate.

[0051] When at least a portion of the support member 5 is constructed as an arc-shaped plate adapted to the shape of the subject's head, the arc-shaped plate ensures comfortable contact between the support member 5 and the subject's head, increases the contact area between them, enhances the cooling effect of the support member 5 on the head, ensures comfort when wearing the head-mounted device, and improves the fit between the support member 5 and the subject's head. Furthermore, the arc-shaped plate does not make hard contact with the head, thus avoiding pressure pain. Therefore, the arc-shaped plate does not need to use flexible materials or have a flexible layer on the side in contact with the head, eliminating the need for flexible materials or structures to ensure comfort in contact with the head.

[0052] The aforementioned arc-shaped plate can be specifically positioned at the head of the object where it is susceptible to heat damage, so that the cold air in the cold air transmission cavity 3 can be concentrated and blown onto the arc-shaped plate, thereby improving the cooling effect of the arc-shaped plate on the head of the object.

[0053] For example, the support member 5 may include multiple arc-shaped plates. These arc-shaped plates may be evenly arranged around the head of the object, or they may be arranged on the left and right sides of the head of the object, or they may be arranged in the four regions of the head of the object. This application does not specifically limit the arrangement of the multiple arc-shaped plates, as long as they can effectively cool the head of the object. Wherein, when there are multiple arc-shaped plates, the interval between each arc-shaped plate and the first shell 1 is constructed as a spacer cavity 51.

[0054] In some embodiments, the arc-shaped plates can be detachably installed inside the first housing 1. The arrangement of the arc-shaped plates can be adaptively adjusted according to different arrangements of the light irradiation units 4, the head's easy-to-fit positions, and areas prone to high temperatures, to achieve a better effect of cooling the head while ensuring head comfort during contact. For example, in scenarios where the light irradiation units 4 cover multiple brain regions of the subject, several relatively lower areas of the first housing 1 that are prone to contact with the head may experience localized high temperatures. In this case, multiple arc-shaped plates can be arranged around the subject's head. As another example, in scenarios where the light irradiation units 4 correspond to specific brain regions, such as when the light irradiation units 4 are arranged to irradiate only the left and right temporal lobes, the occipital region and forehead are less likely to generate high temperatures, and the possibility of thermal damage to the head even if they come into contact is relatively small, the arc-shaped plates can be arranged corresponding to the left and right sides of the subject's head, while other areas may not have arc-shaped plates, achieving targeted comfort assurance and effective cooling.

[0055] As shown in Figures 3 to 5, when at least a portion of the support member 5 is constructed as an annular plate surrounding the head of the object, the spacer cavity 51 is constructed as an annular cavity. In this way, the support member 5, which is constructed as an annular plate, can ensure the comfort of contact when the head is placed against any position. Moreover, it can cool the head of the object circumferentially and uniformly over a larger area during contact, further improving the cooling effect on the head of the object, making the circumferential temperature of the head of the object uniform, and improving comfort.

[0056] For example, the cross-sectional shape of the support member 5 may be L-shaped. The L-shaped support member 5 has a vertical plate and a horizontal plate. The vertical plate is used to form a spacer cavity 51 between itself and the first housing 1, and the horizontal plate is used to connect the support member 5 to the first housing 1.

[0057] Furthermore, the support member 5 located inside the first housing 1 corresponding to the second region 12 can be configured as a guide member, at least partially corresponding to the second region 12. This can be understood as the support member 5 guiding the direction of cold air transmission within the partition cavity 51. Preferably, the support member 5 can guide the cold air exiting the cold air transmission cavity 3 upwards to cool the upper region of the receiving cavity 17.

[0058] In some embodiments, as shown in Figures 1 to 4, the support member 5 forms an exhaust port 52 facing the first region 11. The exhaust port 52 is in fluid communication with the partition cavity 51. As shown in Figure 3, the upper region of the receiving cavity 17 formed between the first region 11 and the object head is connected to the partition cavity 51 through the exhaust port 52. In this way, cold air is first delivered to the partition cavity 51 by the cold air transmission cavity 3. The cold air in the partition cavity 51 can enter the upper region of the receiving cavity 17 through the exhaust port 52. Thus, while ensuring the cooling effect of the support member 5 on the object head, the temperature of the upper region of the receiving cavity 17 can be further reduced.

[0059] It is understandable that the upper region of the receiving cavity 17 can be understood as the relatively upper region when the head-mounted device is worn on the subject's head (or the region around and above the top of the head), and the lower region of the receiving cavity 17 can be understood as the relatively lower region (e.g., below the upper region). Since the cold air in the cold air transmission cavity 3 naturally flows downwards, factors such as insufficient downward flow of gas, an unreasonable gas transmission path design leading to higher temperatures of the delivered cold air, or different distances between the first housing 1 and the subject's head can cause the temperature of the upper region of the receiving cavity 17 to be higher than that of the lower region, and uneven heating or cooling may occur within the receiving cavity 17. Furthermore, during treatment, when the head-mounted device is worn on the subject's head, airflow in the upper region of the receiving cavity 17 slows down. As the treatment duration increases, the heat generated during treatment also increases, causing the temperature in the upper region of the receiving cavity 17 to rise, making effective heat dissipation impossible.

[0060] The cold air in the cold air transmission cavity 3 is guided by the support member 5 to the upper region of the receiving cavity 17 from bottom to top. This allows the cold air to be blown first to the lower region of the receiving cavity 17 and then to the upper region. In other words, the lower region of the receiving cavity 17 is cooled first, and then the upper region is cooled. This allows the temperature of the lower and upper regions of the receiving cavity 17 to be balanced, so that the temperature of each region in the receiving cavity 17 can be evenly distributed. This can be understood as the temperature deviation of each region in the receiving cavity 17 being within a preset range, so as to achieve a better cooling effect.

[0061] In some embodiments, the exhaust port 52 of the support member 5 may be formed by the support member 5 alone, or it may be formed by the support member 5 in conjunction with other components, such as by the support member 5 and the first housing 1. This application does not make specific limitations on this. The exhaust port 52 can communicate with the cold air transmission cavity 3 to discharge part of the cold air in it to the upper region of the receiving cavity 17.

[0062] Of course, after the head is wearing the headgear, the head can also guide the airflow, so as to guide the cold air discharged from the exhaust port 52 directly to the upper area of ​​the receiving cavity 17.

[0063] In some embodiments, the support member 5 may also be constructed as a tubular structure. When the support member 5 is constructed as a tubular structure, the support member 5 may be constructed as a circular tube or other tubular structure, and the cold air in the spacer cavity 51 is guided to be transported upward through the tubular structure.

[0064] This application uses an example of an air inlet 21 on the second housing 2 for supplying cold air to the cold air transmission cavity 3 to illustrate the technical solution of this application. However, this application is not limited to this. Those skilled in the art can set the location of the cold air generating device, whether to open the air inlet 21, and the number, location, and size of the air inlets 21 according to actual needs, as long as there is cold air for cooling in the cold air transmission cavity 3. This application does not make specific limitations in this regard. For example, the air inlet 21 opened on the second housing 2 can be located on the upper part of the second housing 2 or on the side of the second housing 2. As another example, in some embodiments, multiple air inlets 21 can be opened on the upper part of the second housing 2 and the side of the second housing 2 respectively.

[0065] In some embodiments, as shown in Figures 1 to 3, the air inlet 21 is disposed on the upper part of the second housing 2, so that the cold air in the cold air transmission cavity 3 can flow from top to bottom by taking advantage of the property that cold air will naturally be delivered from top to bottom.

[0066] In some embodiments, a support structure may be provided between the first housing 1 and the second housing 2, so that the first housing 1 and the second housing 2 can maintain a relatively stable positional relationship, avoid deformation of the first housing 1 and the second housing 2 under force, and avoid problems affecting the structure of the cold air transmission cavity 3, thereby achieving the purpose of ensuring the flow of cold air in the cold air transmission cavity 3.

[0067] Specifically, the size and number of exhaust ports 52 can be adjusted according to the demand for cold air in the upper region of the receiving cavity 17. For example, if a large amount of cold air is required in the upper region of the receiving cavity 17, more cold air can be provided to the upper region of the receiving cavity 17 by increasing the number and size of the exhaust ports 52.

[0068] The exhaust port 52 can be located at the junction of the first region 11 and the second region 12, or it can be located in the second region 12. The opening of the exhaust port 52 is oriented towards the first region 11, so that the cold air discharged from the exhaust port 52 can directly enter the upper region of the receiving cavity 17. In some other embodiments, the exhaust port 52 can also extend directly into the upper region of the receiving cavity 17 to directly cool the upper region of the receiving cavity 17 with cold air.

[0069] The above structural design allows the cold air to cool the lower areas first from top to bottom, and then be guided by the exhaust port 52 to blow upwards into the upper area of ​​the receiving cavity 17, so that the temperature of each area in the receiving cavity 17 can be evenly distributed, achieving a better cooling effect and improving the patient's comfort during the treatment process.

[0070] In some embodiments, particularly for multi-brain-area irradiation scenarios, such as when light irradiation units 4 are evenly distributed at corresponding positions in the frontal, temporal, and occipital lobes, the temperature inside the receiving cavity 17 will be relatively high when multi-brain-area irradiation is performed with high light power. Areas with large temperature differences are also prone to occur; for example, the temperature of the lower region of the receiving cavity 17, which is close to the patient's head, is much higher than the temperature of the upper region. The temperature gradually rises along the direction of cold air delivery, leading to severe temperature unevenness within the receiving cavity 17. This affects the patient's comfort during treatment and consequently the phototherapy effect. The structural design of this application, in particular, can better cool the various regions within the receiving cavity 17 during multi-brain-area irradiation. It allows cold air to be blown first to the warmer regions and then to the relatively cooler regions, resulting in a more balanced temperature across the receiving cavity 17. This better cools the patient's head in multi-brain-area irradiation scenarios and improves the patient's comfort during phototherapy.

[0071] In some embodiments, as shown in Figures 3 and 4, the exhaust port 52 is formed by the support member 5 mating with the inner side of the first housing 1. The exhaust port 52 connects the spacer cavity 51 with the receiving cavity 17, specifically with the upper region of the receiving cavity 17. This allows full utilization of the structure other than the support member 5 to form the exhaust port 52, i.e., utilizing the first housing 1 to form the exhaust port 52, making the structural design of the transcranial photodynamic therapy device more reasonable and compact.

[0072] In some embodiments, when the bottom of the support member 5 is sealed to the first housing 1, the cold air in the partition cavity 51 can come into full contact with the support member 5, thereby increasing the cooling effect of the support member 5 on the head of the object.

[0073] The exhaust port 52 can be arranged in a ring on the upper side of the support member 5 to discharge cold air in the circumferential direction of the object's head, thereby achieving a better cooling effect on the object's head. Of course, there can be multiple exhaust ports 52, which can be distributed at intervals on the upper side of the support member 5. This application does not impose specific limitations on the number and arrangement of exhaust ports 52, and the exhaust ports 52 can be set according to actual usage requirements.

[0074] In some embodiments, the support member 5 is provided with a second air outlet 53, the opening of the second air outlet 53 is disposed facing the head of the object, and the first air outlet 13 and the second air outlet 53 are misaligned.

[0075] Thus, when the head of the object is not in contact with the support member 5, cool air can be blown towards the head of the object through the second air outlet 53 on the support member 5, thereby reducing the temperature of the corresponding second area 12 of the head and improving comfort and safety. Furthermore, the staggered arrangement of the first air outlet 13 and the second air outlet 53 prevents the cool air blown out of the first air outlet 13 from directly blowing out of the second air outlet 53, reducing the speed of the cool air and preventing it from blowing directly onto the head at a high speed, further enhancing comfort.

[0076] Furthermore, the staggered arrangement of the first air outlet 13 and the second air outlet 53 allows the cold air discharged from the first air outlet 13 to first blow directly onto the support member 5. The cold air makes full contact with the support member 5 first, prioritizing direct cooling of the support member 5 and ensuring its cooling effect. Only then is it delivered from the staggered second air outlet 53 to the receiving cavity 17 between the subject's head and the first shell 1 to cool the head. In this way, it can be ensured that when the subject's head comes into contact with the support member 5, it is in contact with the fully cooled support member 5, preventing thermal damage upon contact. Even if the subject's head blocks the second air outlet 53 when it comes into contact with the support member 5, cold air can still be blown from the first air outlet 13 onto the support member 5, ensuring effective cooling of the support member 5. This further ensures that when the subject's head comes into contact with the support member 5, it is always in contact with the cooled support member 5, thus guaranteeing the safety and comfort of the subject's head during transcranial phototherapy. Furthermore, even if the object head comes into contact with the support member 5 and the object head blocks the second air outlet 53, the cold air discharged from the first air outlet 13 can still be delivered to the upper region of the receiving cavity 17 through the exhaust port 52, thus ensuring the cooling effect on the upper region of the receiving cavity 17.

[0077] In some other embodiments, the support member 5 may not have a second air outlet 53, so that the cold air in the partition cavity 51 can fully cool the support member 5, thereby ensuring that the support member 5 cools the head of the object.

[0078] In some embodiments, there are multiple first air outlets 13 and multiple second air outlets 53. Multiple first air outlets 13 and multiple second air outlets 53 are arranged in groups. This application does not specifically limit the number of second air outlets 53 and the number of first air outlets 13 in the same group. Those skilled in the art can set them according to actual needs. The number of second air outlets 53 in the same group can be greater than, equal to or less than the number of first air outlets 13 in the same group.

[0079] For example, the number of first air outlets 13 in each group is greater than the number of second air outlets 53. For instance, the number of first air outlets 13 can be 5 and the number of second air outlets 53 can be 4. In this way, when the first air outlets 13 and the second air outlets 53 are the same size, the amount of cold air delivered from the cold air transmission cavity 3 to the partition cavity 51 per unit time is greater than the amount of cold air delivered from the partition cavity 51 to the lower region of the receiving cavity 17 through the second air outlets 53. This can prevent the rapid loss of cold air in the partition cavity 51, thereby ensuring the effect of cooling the support member 5 with cold air.

[0080] The first air outlet 13 and the second air outlet 53 in each of the above groups can be set to correspond to a light irradiation unit 4, so as to ensure that the area irradiated by the transcranial light emitted by each light irradiation unit 4 is cooled by corresponding cold air, further reducing the risk of heat damage and specifically cooling the head of the target.

[0081] In some embodiments, at least a portion of the light irradiation unit 4 is disposed correspondingly to the support member 5. In this way, the area irradiated by the portion of the light irradiation unit 4 can directly contact and cool the object's head via the support member 5, avoiding the problem of excessively high local temperature in the irradiated area. Furthermore, the support member 5 can also be used to isolate the light irradiation unit 4 from the object's head, thereby reducing the risk of thermal damage.

[0082] In some embodiments, as shown in Figures 5 to 7 and Figure 11, the support member 5 is provided with a support rib 54 on the side facing the first housing 1, and the support rib 54 abuts against the first housing 1. In this way, the support rib 54 can stabilize and support the support member 5, so that the support member 5 and the first housing 1 can maintain a relatively stable positional relationship, avoiding problems such as deformation of the support member 5 under force that would affect the gas transmission of the partition cavity 51 and the comfort of contact with the head, thereby ensuring the flow of cold air in the partition cavity 51.

[0083] In some embodiments, there may be multiple support ribs 54, which are spaced apart on the side of the support member 5 facing the first housing 1, so that the force on the support ribs 54 is more uniform.

[0084] The support rib 54 and the support member 5 can be integrally formed to ensure the structural relationship between the support member 5 and the support rib 54.

[0085] The support rib 54 can be offset from the light irradiation unit 4 to avoid affecting the irradiation of the light irradiation unit 4, so that the transcranial light emitted by the light irradiation unit 4 can irradiate more of the head of the subject, thus ensuring the treatment effect.

[0086] In some embodiments, the vertically arranged support ribs 54 enable the partition cavity 51 to be divided into at least two independent isolation units. Furthermore, the support ribs 54 seal or partially seal adjacent isolation units. This allows the cold air transmitted through the first air outlet 13 to undergo vertical rectification after entering each isolation unit, reducing turbulence and improving the flow of cold air from the upper end of the support member 5 to the receiving cavity 17, thus enhancing the airflow.

[0087] In some embodiments, there are multiple light irradiation units 4, which are respectively arranged corresponding to the first region 11 and the second region 12 of the first housing 1, and are arranged around the head of the subject. In this way, transcranial light can be emitted to the head of the subject by multiple light irradiation units 4 arranged around the head of the subject, so as to achieve the purpose of fully treating multiple brain regions of the subject's head.

[0088] In some preferred embodiments, the bottom of the support member 5 is sealed to the first housing 1. Specifically, the support member 5 can guide all the cold air from the cold air transfer chamber 3 upwards, or guide a portion of the cold air upwards to the upper region of the receiving cavity 17, while another portion of the cold air can be delivered from other directions to the lower region of the receiving cavity 17, for example, from the side or below of the support member 5. When the bottom of the support member 5 is sealed to the first housing 1, the cold air in the cold air transfer chamber 3 can fully contact the support member 5, and more cold air can be discharged upwards from the exhaust port 52, improving the cooling efficiency of the receiving cavity 17 and / or the support member 5.

[0089] In some embodiments, the support member 5 may include a base plate connected to the first housing 1, and the base plate may be provided with a fourth air outlet (not shown in the figure). When the base plate is provided with a fourth air outlet, the head area and / or neck area of ​​the object corresponding to the area below the second region can be cooled through the fourth air outlet. As shown in Figure 2, the head-mounted device has an opening communicating with the outside, and the cold air in the receiving cavity 17 can circulate with the outside through the opening. Therefore, the area below the second region has a relatively low demand for cooling, and in order to ensure the cooling effect on the area in the receiving cavity 17 that is prone to high temperature, the air outlet area of ​​the fourth air outlet should be smaller than the air outlet area of ​​the exhaust port 52, so that more cold air in the partition cavity 51 can be discharged from the exhaust port 52.

[0090] In some embodiments, at least a portion of the support member 5 is made of a translucent rigid material. In this way, the transcranial light emitted by the light irradiation unit 4 can pass through the translucent support member 5 to reach the subject's head, ensuring comfort when the head rests against the support member 5 and reducing head temperature while maintaining contact. This also enhances the therapeutic effect of the transcranial light modulation device, allowing more of the transcranial light emitted by the light irradiation unit 4 to penetrate the skull and reach the cerebral cortex. Furthermore, the rigid material of the support member 5 prevents deformation due to head pressure, thus avoiding interference with the flow of cold air in the septum 51.

[0091] Furthermore, existing diaphragms, in order to ensure comfort when pressed against the head, are generally made of flexible and translucent materials, such as translucent silicone. Diaphragms made of this material and adapted to the transcranial light irradiation area are complex to manufacture (requiring various complex structural shapes to be designed according to the transcranial light irradiation area), resulting in high costs, susceptibility to deterioration and discoloration (which reduces light-guiding effect), and the generation of odors, as well as a short lifespan. In a preferred embodiment, at least a portion of the support member 5 is constructed as an arc-shaped plate adapted to the shape of the head, and the arc-shaped plate can be made of a translucent rigid material. The rigid material arc-shaped plate can also ensure comfort when the head is pressed against the head. It does not require designing various complex structural shapes to avoid the transcranial light irradiation area, nor does it need to consider the impact of deformation on the flow of cold air in the diaphragm cavity 51. It is also simple to manufacture and low in cost. For example, it can be made of the same rigid translucent material used in the first housing 1. Compared to translucent flexible materials, it is less prone to deterioration and discoloration, does not generate odors after a period of use, and has a longer lifespan.

[0092] In other embodiments, a flexible layer may also be provided on the side of the support member 5 facing away from the first housing 1. The flexible layer can further improve the comfort of contact between the support member 5 and the object's head. The flexible layer may be made of a light-transmitting material so that the transcranial light emitted by the light irradiation unit 4 can pass through the flexible layer and irradiate the object's head.

[0093] In other embodiments, portions of the support member 5 may also be made of flexible materials or constructed as flexible structures to improve the comfort of contact with the object's head.

[0094] For example, the part of the support member 5 that can fit tightly against the head of the object is made of a rigid material, while the part of the support member 5 that does not fit tightly against the head of the object, or fits loosely or not completely, can be made of other materials.

[0095] In some embodiments, as shown in FIG3, a portion of the first air outlet 13 is provided corresponding to the first region 11, so that a portion of the cold air in the cold air transmission cavity 3 can enter the upper region of the receiving cavity 17 through the first air outlet 13 located in the first region 11. In this way, the gas discharged from the first air outlet 13 located in the first region 11 and the gas discharged from the exhaust port 52 can form convection in the upper region of the receiving cavity 17, thereby achieving the purpose of further cooling the upper region of the receiving cavity 17 through the convection of cold air, effectively improving the cooling effect on the head of the object.

[0096] In some other embodiments, the first region 11 may not be provided with the first air outlet 13. Since the cold air in the cold air transmission cavity 3 will naturally be transmitted from top to bottom, the temperature of the first region 11 is already low. In addition, the first region 11 is relatively far from the lower region of the receiving cavity 17, and it is not easy for the head of the subject to come into contact with it during the phototherapy process. Therefore, even if the first region 11 is not provided with the first air outlet 13, the temperature of the first region 11 will not be high.

[0097] In some embodiments, the first region 11 may include a first sub-region and a second sub-region arranged from top to bottom. The first air outlet 13 may be provided on the first sub-region, while the second sub-region may not have the first air outlet 13 provided. When the head-mounted device is worn on the head, the airflow within the cavity 17 becomes poor, especially in the upper region of the cavity 17, which is relatively far from the external environment. As the treatment duration or light power increases, the heat generated during treatment also increases. Furthermore, the cold air discharged from the exhaust port 52 is gradually heated as it rises, and its rising speed may gradually slow down. Therefore, the discharged cold air may not be able to further cool the first sub-region and the upper region of the cavity 17 formed by this region and the head. In particular, when the light power emitted by the light irradiation unit 4 is high, the cold air in the cold air transmission cavity 3 alone may not be able to achieve the expected cooling effect. In this case, opening a small number of first air outlets 13 on the first sub-region can avoid the above problems. The cold air discharged from the first air outlets 13 can further cool the first sub-region and the upper region of the cavity 17 formed by this region and the head, avoiding local high temperatures and keeping the temperature deviation between the sub-region and other parts of the cavity 17 within a preset range, that is, keeping the temperature of all parts of the cavity 17 in a balanced state.

[0098] Furthermore, the cold air discharged from the first air outlet 13 in the first sub-region can effectively convect with the cold air discharged from the exhaust port 52 of the support member 5 in the second sub-region, thereby effectively reducing the temperature of the second sub-region. Moreover, the absence of a first air outlet 13 in the second sub-region allows more cold air in the cold air transmission cavity 3 to flow towards the first air outlet 13 corresponding to the support member 5, enabling more cold air to be discharged into the partition cavity 51 through the first air outlet 13 for better cooling of the support member 5.

[0099] In some other embodiments, a first air outlet 13 may also be provided on the second sub-region, but the air outlet area of ​​the first air outlet 13 on the second sub-region should be much smaller than the air outlet area of ​​the first air outlet 13 on the first sub-region, so that more cold air can be delivered into the partition cavity 51 to achieve a better cooling effect for the support member 5.

[0100] In other embodiments, the first air outlet 13 may not be provided on the first sub-region, so that more cold air in the cold air transmission cavity 3 can be transmitted downward. Since the temperature of the first sub-region is relatively low, the temperature of the first sub-region can be ensured not to be too high even if the first air outlet 13 is not provided.

[0101] In some embodiments, the light irradiation unit 4 may be partially configured corresponding to the first region 11. The light irradiation unit 4 configured corresponding to the first region 11 and the first air outlet 13 opened on the first region 11 may be configured correspondingly to better reduce the temperature of the region directly irradiated by the light irradiation unit 4.

[0102] Preferably, the number of the first air outlets 13 provided on the first region 11 should not be too large, so as to guide more cold air in the cold air transmission cavity 3 into the partition cavity 51, thereby providing more effective cooling for the support member 5.

[0103] In some embodiments, there are multiple first air outlets 13, which are respectively disposed in the first region 11 and the second region 12. The air volume of the first air outlet 13 in the second region 12 is greater than that of the first air outlet 13 in the first region 11, so as to guide more cold air in the cold air transmission cavity 3 to be transmitted downward to the partition cavity 51, ensuring the cooling of the support member 5, thereby reducing the temperature of the area where the object head is in contact with the support member 5, and effectively cooling the object head.

[0104] In some embodiments, the cold air in the cold air transmission chamber 3 is transmitted to the partition chamber 51 via the first air outlet 13 to cool the support member 5. This allows the cold air to be directly blown onto the support member 5, effectively cooling it and reducing the temperature of the area where the subject's head is in contact with the support member 5. This effectively cools the subject's head, improving the safety and comfort of the subject's head during phototherapy. Furthermore, the support member 5 separates the first housing 1 from part of the subject's head, preventing the subject's head from blocking the first air outlet 13 on the inner surface of the first housing 1, thus affecting the cooling effect on the head.

[0105] In some embodiments, the cold air in the cold air transmission chamber 3 is transmitted to the partition chamber 51 via the first air outlet 13 to cool the support member 5, and part of the cold air is transmitted to the upper region of the receiving cavity 17 corresponding to the first region 11 of the first housing 1 via the exhaust port 52 of the support member 5 to cool it. In this way, not only can the support member 5 be cooled, but part of the cold air in the partition chamber 51 can also be guided upward through the exhaust port 52 to provide the delivered cold air from bottom to top to the upper region of the receiving cavity 17 formed between the first region 11 and the head of the patient, so that the temperature of each region in the receiving cavity 17 can be evenly distributed, achieving a better cooling effect and improving the comfort of the patient during the treatment process.

[0106] In some embodiments, as shown in FIG10, the transcranial light modulation device further includes: a first temperature sensing component 6 having a first sensing part 61, the first sensing part 61 being attached to and fixed to the support member 5 to measure the temperature of the support member 5.

[0107] The first sensing part 61 of the first temperature sensing component 6 is attached to and fixed to the support member 5. When the head of the object is attached to the support member 5, the temperature at the position where the head of the object is attached can be obtained in real time. This allows for timely reference to the temperature of the support member 5 to adjust the air conditioning and thus adjust the temperature of the support member 5. This ensures that the head of the object feels comfortable when it is attached to the support member 5 and is not burned, thereby improving the user experience.

[0108] Taking the support member 5 shown in Figures 8 and 10 as an example, which is a plate-like structure, it is positioned at a location where the object's head can easily come into contact with the first shell 1, that is, on the inner side of the first shell 1 corresponding to the second region 12. Depending on the shape and size of the first shell 1, the position of the support member 5 can vary. For example, the bottom of the first shell 1 may have a lower protrusion 14, and the support member 5 may be positioned close to the lower protrusion 14. Specifically, the lower protrusion 14 is positioned corresponding to the left and right ears when the object's head is in place. As shown in Figure 8, the support member 5 is formed in the upper half of the ear and / or above the ear. This part is located precisely where the diameter of the head's cross-section is larger, or precisely in the area near the occipital protuberance, where the head's curved surface is raised and the hair coverage is thicker than other head areas. This facilitates closer contact with the object's head and also facilitates the dissipation of localized heat caused by the large amount of hair absorbing heat. The support member 5 can be constructed as a ring-shaped plate or an L-shaped plate, such as a semi-ring-shaped plate.

[0109] In some embodiments, the support member 5 can be constructed entirely of a light-transmitting material. This allows transcranial light to pass through the support member 5 and enter the receiving cavity 17 for phototherapy of the subject's head. During installation, the support member 5 does not need to avoid the light irradiation unit 4, and its installation position can be more diverse to meet the phototherapy needs of different subjects.

[0110] In some embodiments, the light illumination unit 4 can be in the form of an LED light such as a light panel, LED beads, or light mesh, or it can be a light guide structure such as an optical fiber, as long as it can apply transcranial light illumination to the head of the object. This application does not make any specific limitations in this regard. Taking the light illumination unit 4 as a light panel as an example, one or more light panels can be distributed on the transcranial light control device to illuminate different positions of the head of the object.

[0111] In some embodiments, when multiple light panels are distributed on the transcranial light modulation device, the multiple light panels can be arranged in layers from top to bottom along the transcranial light modulation device. A light panel can also be placed at the position corresponding to the lower protrusion 14 to provide more comprehensive illumination of the brain, especially the temporal lobe around the ear, and even deep within the temporal lobe through the ear canal, such as the hippocampus.

[0112] In some embodiments, the lower protrusion 14 may also be provided with an air hole for transmitting cold air. Preferably, the air hole is opened at the bottom of the lower protrusion 14. The opening position of the air hole can guide part of the cold air to be delivered to the corresponding head and / or neck position of the object below, so that the cold air delivered below can cool the head and neck of the object. It can also circulate well with the air in the accommodating cavity (or the outside world) and prevent the exhaust cold air from blowing directly onto the head of the object (e.g., the ears), so as to effectively cool the head and neck of the object and improve comfort.

[0113] The lower protrusion 14 can be understood as the area formed on the ear and near the ear contour of the corresponding object's head. The object's head corresponding to the lower protrusion 14 has less hair, making it less prone to heat accumulation. Furthermore, the lower part of the head-mounted device is open, and the lower protrusion 14 is closer to the external environment than the first region 11 and the second region 12. Therefore, designing a small number of vents below it is sufficient to meet the cooling needs of the object's head and neck.

[0114] In some embodiments, each layer of the light panel may include one or more light panels. Each light panel may contain at least one light-emitting unit. The light-emitting units may be arranged in an array such as 3×3, 2×2, or 2×3 on the light panel, and the light-emitting units can emit an average power density of 40 mW / cm² towards the corresponding brain region (or the entire brain region). 2 -120mW / cm 2 Near-infrared light. In some embodiments, the light panel can be configured to correspond to different brain regions, such as the occipital lobe, temporal lobe, frontal lobe, and parietal lobe, to perform targeted transcranial phototherapy and improve the therapeutic effect of transcranial phototherapy.

[0115] In some embodiments, as shown in Figures 10, 11, and 12, a slot 55 is formed at a predetermined position on the support member 5. The first sensing part 61 extends into the slot 55 and abuts against the first inner groove wall of the slot 55 on the receiving cavity 17 side. The slot 55 provides a connection position between the first temperature sensing part 6 and the support member 5, and also constrains the first temperature sensing part 6 so that its first sensing part 61 can stably abut against the first inner groove wall.

[0116] As shown in Figures 12 and 13, in some embodiments, a first opening 58 may be provided on the slot 55. This allows the first temperature sensing component 6 to pass through the first opening 58 and abut against the first inner groove wall. The first opening 58 is opposite to the first housing 1 and is located on the second inner groove wall opposite to the first inner groove wall, facilitating the routing of some structures of the first temperature sensing component 6, such as cables, from the housing, thus avoiding interference with the use of the transcranial light modulation device.

[0117] In some embodiments, the first temperature sensing component 6 may be disposed in the first housing 1, or simultaneously disposed in the second housing 2 and the first housing 1, so as to fix the structure other than the first sensing part 61 of the first temperature sensing component 6, improve the stability of the first temperature sensing component 6, and also output the temperature measurement result through a transmission method such as a circuit connected to the first temperature sensing component 6.

[0118] In some embodiments, as shown in Figures 10 and 13, the transcranial optical modulation device further includes a fixing member 7. The fixing member 7 passes through the first housing 1 from the outside, extends into the slot 55, and abuts against the first sensing part 61 to press the first sensing part 61 against and fit against the first inner groove wall of the slot 55. The fixing member 7 can reduce the shaking of the first sensing part 61 and the possibility of it detaching from the first inner groove wall. The fixing member 7 can be a structure with a fixing function, such as a fixing pin, to extend into the slot 55 and abut against the first sensing part 61, so that the first sensing part 61 can fit against the first inner groove wall.

[0119] In some embodiments, the first temperature sensing component 6 may be a component capable of measuring the temperature of the support member 5, such as a temperature sensor or NTC sensor (negative temperature coefficient temperature sensor).

[0120] In some embodiments, as shown in Figures 10, 11, and 12, a filling port 56 is provided on the slot 55 to fill it with thermally conductive adhesive. The thermally conductive adhesive serves to constrain the first sensing unit 61, and it does not affect the first sensing unit 61's measurement of the temperature of the support member 5. The filling port 56 can be located at the lower end of the slot 55. When the transcranial Doppler device is inverted during the filling of the thermally conductive adhesive, the filling port 56 is located at the "upper end" of the slot 55, facilitating the filling of the thermally conductive adhesive.

[0121] After the first sensing part 61 in the slot 55 is held in place by the fixing member 7, the first sensing part 61 is subjected to the pressure. The entire first temperature sensing component 6 is constrained by the slot 55 and the first housing 1. In addition, the thermal conductive adhesive filled into the slot 55 also provides constraint, so that the first temperature sensing component 6 will not shake when using the transcranial light control device, thus improving the stability of the device.

[0122] In some embodiments, the support member 5 has a transverse flange extending toward the inner wall of the first housing 1. The transverse flange connects with the inner wall of the first housing 1 to form a blocking portion. The blocking portion blocks the cold air transmitted from the first air outlet 13 from continuing to travel there and redirects it to the opposite direction. The blocking portion can be a lower flange, an L-shaped blocking portion, a lower baffle, etc.

[0123] In some embodiments, a lower protrusion 14 is formed on the lower part of the first housing 1, the lower protrusion 14 corresponding to the ear irradiation area of ​​the transcranial light modulation device, and a slot 55 is provided on the support member 5 at a position corresponding to the lower protrusion 14.

[0124] The support member 5 can extend circumferentially. There are one or more slots 55 on the support member 5. A lower protrusion 14 is formed at the bottom of the first housing 1, corresponding to the ear irradiation area of ​​the transcranial light modulation device. The slots 55 are located on the support member 5 at positions corresponding to the lower protrusion 14. As shown in Figure 10, the slots 55 are located on the support member 5 near the lower protrusion 14. It is understood that the position of the support member 5 near the ear irradiation area is at the lower end of the cold air transmission path, and the ear irradiation area also has a corresponding light irradiation unit 4, which continuously generates heat during treatment. Therefore, the temperature at this location may be high. Setting the slots 55 on the support member 5 at positions corresponding to the lower protrusion 14 facilitates temperature measurement near this location, allowing for temperature control and preventing burns to the subject's head due to excessive heat.

[0125] Two lower protrusions 14 may be formed at the bottom of the first housing 1, and one or more slots 55 may be provided. Multiple slots 55 may be located at corresponding positions of the two lower protrusions 14, that is, one or more slots 55 may be provided at the corresponding position of each lower protrusion 14 to measure the temperature at the corresponding position.

[0126] According to embodiments of this application, a method for assembling a transcranial light-modulating device can also be provided. The transcranial light-modulating device includes a second housing 2 and a first housing 1 disposed inside the second housing 2, a support member 5, a first temperature sensing component 6, and a fixing member 7. A slot 55 is formed on the support member 5. As shown in FIG14, the assembly method includes steps 101 to 103.

[0127] In step 101, a first temperature sensing component 6 with a first sensing part 61 is passed through the first housing 1 and inserted into a slot 55 on the support member 5. In step 102, a fixing member 7 is passed through the first housing 1 from the outside and inserted into the slot 55 to abut against the first sensing part 61 of the first temperature sensing component 6, so that the first sensing part 61 of the first temperature sensing component 6 is abutted against and attached to the first inner groove wall of the slot 55, the first inner groove wall being the inner groove wall of the slot 55 on the receiving cavity 17 side. In step 103, with the first sensing part 61 of the first temperature sensing component 6 abutted against and attached to the first inner groove wall of the slot 55, thermally conductive adhesive is injected into the slot 55 through the injection port 56 on the slot 55, and the thermally conductive adhesive is allowed to cure.

[0128] In some embodiments, the first temperature sensing component 6 pre-passes through the first housing 1 and extends into the slot 55, facilitating installation and confining the first sensing portion 61 of the first temperature sensing component 6 within the slot 55. Then, the mounting fastener 7 further secures the first temperature sensing component 6. Thermally conductive adhesive is injected after the first sensing portion 61 abuts against and conforms to the first inner wall of the slot 55. The thermally conductive adhesive serves to conduct heat and confine and secure the first sensing portion 61; even if the thermally conductive adhesive flows into the gap between the first sensing portion 61 and the first inner wall, it will not affect the first temperature sensing component 6's measurement of the temperature of the support member 5.

[0129] In some embodiments, when assembling the first temperature sensing component 6, the transcranial light modulation device can be adjusted to a preset posture first, and then assembled according to steps 101 to 103 above to complete the assembly operation of the first temperature sensing component 6. The preset posture can be achieved by inverting the transcranial light modulation device so that the lower protrusion 14 of the transcranial light modulation device faces upwards. In some embodiments, the second housing 2, the first housing 1, and the support member 5 of the transcranial light modulation device can be assembled first, and then the assembly operation of the first temperature sensing component 6 can be performed according to the steps / embodiments above.

[0130] In some embodiments, as shown in Figures 1 and 8, the transcranial photodynamic therapy device further includes a second temperature sensing component 8, which is disposed corresponding to the first region 11 of the first housing 1, and has a second sensing part 81 for extending into the receiving cavity 17 to obtain temperature information within the receiving cavity 17. Preferably, the second sensing part 81 can extend into the upper region of the receiving cavity 17 and make full contact with the air in the upper region of the receiving cavity 17 to accurately obtain temperature information in the upper region of the receiving cavity 17.

[0131] It should be noted that when using higher light power density for treatment, or as the treatment duration increases, the temperature in the upper region of the receiving cavity 17 will rise. Since a large amount of cold air is preferentially guided to the lower region of the receiving cavity 17, the temperature in the upper region of the receiving cavity 17 may exceed the expected range. When using the cold air discharged from the exhaust port 52 to further cool the upper region of the receiving cavity 17, the cold air discharged from the exhaust port 52 is gradually heated as it rises, and the rising speed gradually slows down. High temperatures or uneven temperatures may occur in various areas within the receiving cavity 17. In this case, to ensure the safety and comfort of the patient's head during treatment, a second temperature sensing component 8 is installed in the relatively upper first region 11 of the first housing 1. This second temperature sensing component 8 accurately monitors the temperature in the upper region of the receiving cavity 17, allowing the operator to understand the temperature situation based on the monitoring results. This provides a more reasonable reference for the temperature control of the transcranial light modulation device, reduces the risk of thermal damage to the patient's head during treatment, and provides a comfortable environment for the patient during treatment.

[0132] When the temperature value detected by the second temperature sensing component 8 exceeds a certain threshold, it indicates that the temperature in the upper region of the receiving cavity 17 is too high. At this time, there is a risk of heat damage to the subject's head. The temperature in the upper region of the receiving cavity 17 can be reduced by increasing the amount of cold air transmitted through the exhaust port 52. Alternatively, if the temperature in the upper region of the receiving cavity 17 continues to rise, the light irradiation unit 4 can be turned off, or the headpiece can be removed to stop the treatment and ensure the subject's safety.

[0133] In some embodiments, the first region 11 includes a first sub-region and a second sub-region below it. Multiple second temperature sensing components 8 are disposed in a staggered manner on the first and second sub-regions. Thus, by staggering the second temperature sensing components 8 on the first and second sub-regions, the temperatures of both sub-regions can be comprehensively sensed. This allows for a comprehensive assessment of the temperature within the upper region of the receiving cavity 17, ensuring the accuracy of temperature monitoring in the upper region of the receiving cavity 17. The temperature measurement results can provide a more reasonable reference for temperature control of the transcranial light therapy device, effectively improving the comfort and safety of users. Furthermore, this allows for a more comprehensive and reasonable characterization of the temperature within the upper region of the receiving cavity 17 using fewer second temperature sensing components 8.

[0134] In other embodiments, the second temperature sensing element 8 may be disposed only in the first sub-region or the second sub-region.

[0135] For example, multiple second temperature sensing components 8 can be provided in the first sub-region. For instance, second temperature sensing components 8 can be provided in different directions corresponding to the head to monitor the temperature in the upper region of the receiving cavity 17 corresponding to the first sub-region, so as to determine the temperature felt by the head of the subject, thereby accurately judging the comfort of the subject during the treatment process.

[0136] For example, multiple second temperature sensing components 8 can be provided in the second sub-region. The second sub-region is closer to the subject's head than the first sub-region, making it easier for them to come into contact. After the subject's head enters the receiving cavity 17, the airflow in this region will also decrease. Specifically, when the first sub-region has a first air outlet 13, the cold air delivered downwards from the first air outlet 13 and the cold air delivered upwards from the exhaust port 52 can form convection in the second sub-region. Therefore, cooling of the second sub-region and its corresponding upper region of the receiving cavity 17 can be achieved through the convection of cold air. To ensure the safety and comfort of the subject using the transcranial light therapy device, it is necessary to strictly monitor whether the temperature of the second sub-region and its corresponding upper region of the receiving cavity 17 achieves the expected cooling effect. Specifically, second temperature sensing components 8 can be provided on opposite sides of the second sub-region to monitor the temperature of that region.

[0137] Multiple second temperature sensing components 8 can be respectively set in different directions on the first sub-region and / or the second sub-region, or set at different heights on the first sub-region and / or the second sub-region. This application does not make specific limitations in this regard. It can realize the accurate determination of the temperature in the upper region of the accommodating cavity 17 based on the temperature values ​​monitored by multiple second temperature sensing components 8, so as to provide a more accurate and reasonable reference for the temperature control of the transcranial light control device.

[0138] For example, two second temperature sensing components 8 can be provided on the first sub-region and two second temperature sensing components 8 can also be provided on the second sub-region. The two second temperature sensing components 8 on the first sub-region can be distributed on the left and right sides of the object's head and located at the first horizontal height. The two second temperature sensing components 8 on the second sub-region can be distributed on the front and back sides of the object's head and located at the second horizontal height. The first horizontal height is higher than the second horizontal height. With the cooperation of the four second temperature sensing components 8, the temperature information in the upper region of the receiving cavity 17 can be comprehensively monitored.

[0139] In some embodiments, the transcranial light modulation device further includes a mounting assembly 9 for mounting the second temperature sensing component 8. The mounting assembly 9 includes a support frame 91 disposed in the receiving cavity 17. The support frame 91 and the first housing 1 surround a mounting cavity 92 that accommodates the second sensing part 81 of the second temperature sensing component 8. The mounting cavity 92 is connected to the receiving cavity 17.

[0140] Thus, the second sensing part 81 of the second temperature sensing component 8 is disposed within the mounting cavity 92 formed between the support frame 91 and the first housing 1. The mounting cavity 92 is connected to the receiving cavity 17, allowing the second sensing part 81 to fully contact the gas in the upper region of the receiving cavity 17, thereby ensuring the accuracy of the detected temperature value. Furthermore, the support frame 91 can also prevent the user's head from contacting the second temperature sensing component 8 when using the head-mounted device, protecting the user's head and preventing damage to the second temperature sensing component 8 from impacts.

[0141] The support frame 91 may have multiple legs, and vents may be formed between adjacent legs. The second sensing part 81 of the second temperature sensing component 8 can directly contact the air in the upper region of the receiving cavity 17 through the vents to ensure the accuracy of the monitoring results. It can be understood that the larger the distance between multiple adjacent legs, the greater the air permeability of the vents, that is, the less cold air is blocked by the support frame 91. As a result, the second sensing part 81 can better directly contact the air in the upper region of the receiving cavity 17, thereby increasing the accuracy of the temperature results monitored by the second sensing part 81.

[0142] For example, as shown in FIG8, the support frame 91 shown in the figure has four legs, which can form four vents in different directions, so that cold air can come into contact with the second sensing unit 81 from four directions, thereby improving the accuracy of the second temperature sensing component 8 in monitoring the temperature.

[0143] In some embodiments, as shown in FIG9, the side of the support frame 91 facing away from the first housing 1 is constructed as an arc-shaped surface. Thus, when the subject wears the transcranial light-modulated device for treatment, the support frame 91 with an arc-shaped surface can avoid hard contact between the head-mounted device and the subject's head, improve the fit between the subject's head and the support frame 91, and enhance the comfort of the transcranial light-modulated device.

[0144] In some embodiments, the support frame 91 may have an arc-shaped plate detachably connected to the legs, with the arc surface formed on the arc-shaped plate. In some embodiments, there may be multiple specifications of the arc-shaped plate, and the curvature of the arc surface of the arc-shaped plate of different specifications may be different to adapt to different head shapes or different positions of the head. For different object heads or different positions of the head, an arc-shaped plate that is adapted to it can be selected and installed on the legs to further improve the adaptability of the support frame 91 to the object head.

[0145] In some embodiments, as shown in FIG9, the mounting assembly 9 further includes a mounting base 93 disposed in the cold air transmission cavity 3. The first housing 1 is provided with a mounting hole. The mounting base 93 is used to seal the second temperature sensing component 8 in the mounting hole to avoid poor sealing, which would cause the cold air in the cold air transmission cavity 3 to pass through the gap between the shielding part 31 and the first housing 1 and enter the upper region of the receiving cavity 17 through the mounting hole, thereby causing the temperature monitored by the second temperature sensing component 8 to be inaccurate.

[0146] The mounting base 93 can be arranged circumferentially around the outer side wall of the second temperature sensing component 8, and one end of the mounting base 93 can abut against the mounting hole, while the other end of the mounting base 93 can abut against the inner side wall of the second housing 2, so as to stably mount the second temperature sensing component 8 on the head-mounted device via the mounting base 93.

[0147] To further improve the sealing performance of the mounting base 93 and the accuracy of the monitoring results of the second temperature sensing element 8, and to ensure that the portion of the second temperature sensing element 8 located in the cold air transmission cavity 3 is isolated from the cold air inside the cold air transmission cavity 3, a sealing element can be provided at the joint between the mounting base 93 and the first housing 1 to further ensure the sealing performance. The sealing element can be made of a non-thermal conductive adhesive sealing material to prevent affecting the temperature measurement results of the second temperature sensing element 8, or it can be made of other materials; this application does not impose any limitations on this comparison.

[0148] Specifically, the first temperature sensing component 6 and the second temperature sensing component 8 are respectively disposed at different positions in the corresponding receiving cavity 17. The second temperature sensing component 8 is disposed in the upper region of the receiving cavity 17, and the first temperature sensing component 6 is disposed on the supporting member 5, that is, the first temperature sensing component 6 is disposed in the lower region of the receiving cavity 17. The first temperature sensing component 6 is lower than the second temperature sensing component 8. The temperature value measured by the second temperature sensing component 8 is representative of the temperature at that position in the receiving cavity. Based on the second temperature sensing component 8, the first temperature sensing component 6 is used to measure the temperature of the supporting member 5, which can realize temperature monitoring of multiple key locations. The temperature monitoring results obtained by the first temperature sensing component 6 and the second temperature sensing component 8 can provide a more accurate and reasonable reference for the overall temperature control in the receiving cavity 17 of the transcranial optical transcranial light control device, thereby reducing the risk of thermal damage to the patient's head during treatment, improving the patient's head comfort, and providing a comfortable environment for the patient throughout the treatment process.

[0149] In some embodiments, as shown in FIG9, a third air outlet 15 is provided on the first housing 1 near the side of the second temperature sensing component 8 that is close to the support member 5.

[0150] When the head of the object is against the support member 5, the hair on the head may obstruct the area near the second temperature sensing element 8, affecting its measurement results. In particular, the side of the second temperature sensing element 8 closest to the support member 5 is more affected by hair obstruction than other positions. A third air outlet 15 is provided near the side of the second temperature sensing element 8 closest to the support member 5, allowing a small amount of cold air from the cold air transmission chamber 3 to enter the receiving chamber 17 through the third air outlet 15. This reduces the impact of hair on the measurement results of the second temperature sensing element 8 when the head of the object is against the support member 5, ensuring the accuracy of the measurement results.

[0151] In some embodiments, when a portion of the first air outlet 13 is provided on the first region 11, when the cold air delivered by the portion of the first air outlet 13 passes through the support frame 91, the area below the second temperature sensing component 8 is blocked by the support frame 91, which easily leads to insufficient contact between the detection surface of the detection end of the second temperature sensing component 8 and the cold air in the upper region of the receiving cavity 17 in this area, resulting in inaccurate temperature values ​​and thus inaccurate temperature judgment in the upper region of the receiving cavity 17. By providing a third air outlet 15, a small amount of cold air in the cold air transmission cavity 3 can be delivered to a position near the side of the second temperature sensing component 8 near the support member 5, specifically the area below the second temperature sensing component 8, to ensure the temperature balance of the second temperature sensing component 8 in the circumferential direction, thereby ensuring the accuracy of the monitoring by the second temperature sensing component 8.

[0152] Specifically, the number and size of the third air outlet 15 can be determined based on the location of the area near the second temperature sensing component 8 that is obstructed, and this application does not impose any limitations on this. To ensure the temperature balance around the second temperature sensing component 8, this can be achieved by adjusting the number and size of the third air outlet 15. Preferably, to avoid the amount of cold air delivered by the third air outlet 15 affecting the amount of cold air delivered by the exhaust port 52 to the upper region of the receiving cavity 17, and to ensure the accuracy of the measurement by the second temperature sensing component 8, the amount of cold air delivered through the third air outlet 15 should be relatively small. For example, if the first air outlet 13 is provided on the first sub-region, the total air outlet area of ​​the third air outlet 15 should be much smaller than the total air outlet area of ​​the first air outlet 13 provided on the first sub-region; if the first air outlet 13 is not provided on the first sub-region, the total air outlet area of ​​the third air outlet 15 should be much smaller than the total air outlet area of ​​the first air outlet 13 provided on the first housing 1 corresponding to the support member 5.

[0153] In some embodiments, as shown in FIG9, the transcranial light modulation device further includes a shielding part 31 disposed in the cold air transmission cavity 3. The shielding part 31 is disposed around the second temperature sensing component 8, so that the cold air in the cold air transmission cavity 3 flows around the second temperature sensing component 8.

[0154] Thus, by providing the shielding part 31, the cold air in the cold air transmission cavity 3 can flow around the second temperature sensing component 8 at this location, preventing the cold air in the cold air transmission cavity 3 from blowing directly onto the second temperature sensing component 8 and affecting the measurement accuracy of the second temperature sensing component 8. Specifically, when the second temperature sensing component 8 passes through the cold air transmission cavity 3 and its second sensing part 81 extends into the upper region of the receiving cavity 17, since the temperature of the cold air in the cold air transmission cavity 3 is generally less than or equal to the temperature of the cold air in the upper region of the receiving cavity 17, in order to avoid the second temperature sensing component 8 coming into contact with the cold air in the cold air transmission cavity 3 and affecting the accuracy of the temperature monitoring of the upper region of the receiving cavity 17 by the second temperature sensing component 8, the shielding part 31 is provided around the second temperature sensing component 8 to isolate the second temperature sensing component 8 from the cold air in the cold air transmission cavity 3, thereby ensuring the accuracy of the temperature monitoring results of the second temperature sensing component 8 in the upper region of the receiving cavity 17.

[0155] The shielding part 31 can be arranged around the outer wall of the second temperature sensing component 8, and one end of the shielding part 31 can abut against the outer wall of the first housing 1, and the other end of the shielding part 31 can abut against the inner wall of the second housing 2, so as to prevent cold air from blowing towards the second temperature sensing component 8 through the gap between the shielding part 31 and the first housing 1, or through the gap between the shielding part 31 and the second housing 2.

[0156] The shielding part 31 can be integrally formed on the first housing 1 or the second housing 2, or it can be detachably connected to the first housing 1 or the second housing 2. This application does not specifically limit the arrangement of the shielding part 31.

[0157] In some embodiments, transcranial photomodulation devices are used to treat brain function-related disorders, particularly neurodegenerative diseases such as Alzheimer's disease, mild cognitive impairment, and dementia, and can also be used to treat mental illnesses such as depression, autism, and bipolar disorder.

[0158] It is understood that when using the above-mentioned transcranial light modulation device to treat diseases such as Alzheimer's disease (AD), mild cognitive impairment, dementia, depression, autism and bipolar disorder, the irradiation parameters of the transcranial light can be specifically set according to the type and severity of the disease. This application does not make specific limitations in this regard. The irradiation parameters may include average light power density, pulse frequency, etc.

[0159] In some preferred embodiments, the transcranial photodynamic therapy device described above is used to treat patients with Alzheimer's disease (AD). These patients, in addition to cognitive decline, also experience emotional and mental health issues, such as agitation, anxiety, irritability, and temperature insensitivity. Furthermore, for these patients, a loosely designed headband device (as shown in Figures 3 and 8, allowing for a certain degree of head movement when worn) is required, along with a high optical power density to achieve effective treatment. Therefore, when using the transcranial photodynamic therapy device to treat this specific patient with Alzheimer's disease (AD), there are high requirements for temperature and comfort during the treatment process. The solution proposed in this application can ensure the comfort and safety of the patient's head when it is in contact with the headband device, while also achieving uniform temperature distribution within the cavity 17, resulting in a better cooling effect. This improves the comfort and compliance of Alzheimer's disease (AD) patients during treatment, significantly extends the duration of a single treatment session, and thus ensures a good treatment outcome.
