Description

Technical Field

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

[0002] Existing transcranial light regulation devices reduce the high temperature caused by light irradiation by introducing cold air into the accommodation cavity of the headgear for accommodating the patient's head. The existing design is to set air holes at various positions corresponding to the head on the inner shell of the headgear, and the cold air blows directly towards the object's head through each air hole, thereby achieving cooling for the object's head. Currently, due to the symptom characteristics of patients, long light therapy time, etc., during the light therapy process, it often happens that the patient's head leans against the inner shell. The leaning of the head will block the air holes set at this position on the inner shell, resulting in difficulty for the cold air to be delivered to the accommodation cavity through the air holes at this position, causing the temperature at this position to rise rapidly and causing discomfort to the patient.

[0003] Some existing solutions are to block the patient's head from leaning against the inner wall by setting a spacer on the inner side of the headgear. However, the blocking effect of the spacer is limited, and the air holes may still be blocked by hair, resulting in too high local temperature, poor heat dissipation effect, easy thermal damage to the head, affecting the comfort of the patient during the treatment process, and thus affecting the treatment effect. Summary of the Invention

[0004] In view of the above technical problems existing in the prior art, this application provides a transcranial light regulation device, which can directly blow cold air towards the abutting member that abuts against the object's head, and cool the head when the object's head abuts by cooling the abutting member, improving the safety and comfort of the object's head.

[0005] An embodiment of this application provides a transcranial light regulation device, which includes a head-mounted device, a light source assembly, and an abutting member. The head-mounted device is worn on the object's head and forms an accommodation cavity for accommodating the object's head. The head-mounted device includes a first shell and a second shell covering the outside of the first shell, and a first cold air transmission cavity is formed between the first shell and the second shell. The light source assembly is arranged on the outside of the first shell and is used to emit transcranial light towards the object's head. The abutting member is arranged on the inside of the first shell, and a second cold air transmission cavity is formed between the abutting member and the first shell. The abutting member can abut against the object's head during the treatment process. The first shell is provided with a first air outlet hole communicated with the first cold air transmission cavity, and at least part of the first air outlet holes are arranged corresponding to the second cold air transmission cavity, so that the cold air in the first cold air transmission cavity blows towards the abutting member.

[0006] In some embodiments, the first shell has a first area that can abut against the object's head, and the abutting member is arranged corresponding to the first area.

[0007] In some embodiments, at least a part of the abutting member is configured as an arc-shaped plate adapted to the shape of the object's head.

[0008] In some embodiments, the abutting member is configured as an annular plate disposed around the object's head, and the second cold air transmission cavity is configured as an annular cavity.

[0009] In some embodiments, the first housing further has a second region located above the first region, and a spacing cavity is formed between the second region and the object's head, and the spacing cavity is communicated with the second cold air transmission cavity.

[0010] In some embodiments, an air outlet channel is formed between the upper side of the abutting member and the first housing, and the air outlet channel communicates the second cold air transmission cavity with the accommodation cavity.

[0011] In some embodiments, a support portion is provided on the side of the abutting member facing the first housing, and the support portion abuts against the first housing.

[0012] In some embodiments, a second air outlet hole is provided on the abutting member, and the first air outlet hole and the second air outlet hole are arranged in a staggered manner.

[0013] In some embodiments, both the second air outlet holes and the first air outlet holes are multiple, and the multiple second air outlet holes and the multiple first air outlet holes are arranged in corresponding groups, and the number of the second air outlet holes in the same group is less than the number of the first air outlet holes.

[0014] In some embodiments, the light source assembly is at least correspondingly arranged with the abutting member.

[0015] In some embodiments, the portion of the abutting member that can abut against the object's head is made of a light-transmitting hard material.

[0016] In some embodiments, the bottom of the abutting member is hermetically connected to the first housing; or, the abutting member includes a bottom plate connected to the first housing, and a third air outlet hole is provided on the bottom plate.

[0017] In some embodiments, at least some of the first air outlet holes are correspondingly arranged with the second region, so that the cold air in the first cold air transmission cavity can enter the accommodation cavity through the first air outlet holes located in the second region.

[0018] In some embodiments, the transcranial light modulation device is used to treat at least one of neurodegenerative diseases and mental diseases.

[0019] Compared with the prior art, the beneficial effects of the embodiments of the present application are as follows: Through the first air outlet hole on the first housing, the cold air in the first cold air transmission cavity can be delivered to the second cold air transmission cavity, thereby enabling the cold air to directly blow towards the abutting member. The cold air can reduce the temperature of the abutting member to effectively cool the abutting member. The abutting member separates the first housing from a part of the object's head, preventing the object's head from always abutting against the inner side surface of the first housing. Moreover, by cooling the abutting member, the temperature of the area where the object's head abuts against the abutting member can be reduced. Thus, the object's head can be effectively cooled, avoiding the situation where the object's head temperature is too high during treatment, reducing the risk of thermal injury, and improving the safety and comfort of the object's head during the light treatment process.

The following will further describe the embodiments of this application in detail with reference to the accompanying drawings and specific examples, but it shall not be construed as a limitation to this application.

[0030] The "first", "second" and similar terms used in this application do not indicate any order, quantity or importance, but are only used to distinguish different parts. Words such as "including" or "comprising" mean that the elements before this word cover the elements listed after this word, and do not exclude the possibility of also covering other elements.

[0031] In this application, when it is described that a specific device is located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When it is described that a specific device is connected to other devices, the specific device may be directly connected to the other devices without an intermediate device, or may not be directly connected to the other devices but have an intermediate device.

[0032] All terms used in this application (including technical terms or scientific terms) have the same meaning as understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0033] For technologies, methods and devices known to those of ordinary skill in the relevant art, they may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the specification.

[0034] The embodiments of this application provide a transcranial light modulation device. As Figure 1 and Figure 2As shown in the figure, the transcranial light regulation device includes a head-mounted device, a light source assembly 4, and a cushioning member 5. The head-mounted device forms a receiving cavity for accommodating the head of the subject. The head-mounted device includes a first housing 1 and a second housing 2 covering the outside of the first housing 1. A first cold air transmission cavity 3 is formed between the first housing 1 and the second housing 2. The light source assembly 4 is disposed on the outside of the first housing 1 and is used to emit transcranial light to the head of the subject, such as near-infrared light that can penetrate the skull and act on the cerebral cortex. The cushioning member 5 is disposed on the inside of the first housing 1, and a second cold air transmission cavity 51 is formed between the cushioning member 5 and the first housing 1. The cushioning member 5 can be in contact with the head of the subject during the treatment process. The first housing 1 is provided with a first air outlet 11 communicating with the first cold air transmission cavity 3, and at least a part of the first air outlet 11 is disposed corresponding to the second cold air transmission cavity 51, so that the cold air in the first cold air transmission cavity 3 blows towards the cushioning member 5.

[0035] The above-mentioned head-mounted device can be worn on the head of the subject during light therapy, and the head of the subject is placed inside the first housing 1. When wearing the above-mentioned head-mounted device, when the head of the subject shakes in the receiving cavity or the body is fatigued, some areas of the head are likely to come into contact with the cushioning member 5. If the temperature of the cushioning member 5 is too high, the excessive temperature can be transmitted to some areas of the head of the subject through the cushioning member 5, which is likely to cause thermal damage. Moreover, when the head is close to or even in contact with the cushioning member 5, the gap between the head and the cushioning member 5 decreases or may even have no gap, resulting in a poor heat dissipation effect. As the duration of light therapy increases, the temperature of this part of the area will become higher and higher. If there are black or gray hairs in this head area, it will further accumulate heat, leading to an excessive local temperature and easily causing thermal damage.

[0036] It can be understood that the cold air in the first cold air transmission cavity 3 can be supplied by a cold air supply device, such as a refrigerator, or can be supplied by other cold air manufacturing devices, such as a fan. Specifically, the cold air supply device can be set outside the head-mounted device, or on or inside the head-mounted device, such as being set in the first cold air transmission cavity 3. The present application does not make specific limitations on the supply source of the cold air, the installation position of the cold air supply device, etc., as long as there is cold air in the first cold air transmission cavity 3 that can be delivered to the cushioning member 5.

[0037] Exemplarily, when the cold air supply device is set outside the head-mounted device, the second housing 2 can be provided with an air inlet, and the cold air supply device provides cold air for the first cold air transmission cavity 3 through the air inlet.

[0038] It should be noted that the "cold air" in this application means a gas with a temperature lower than the temperature in the accommodation cavity during transcranial light therapy. It does not limit the temperature of the gas in the first cold air transmission cavity 3 to a specific value or a specific range. Those skilled in the art can understand that as long as the temperature of the gas delivered to the accommodation cavity is lower than the temperature in the accommodation cavity during transcranial light therapy, it can achieve a certain cooling effect.

[0039] It should be noted that the above light source assembly 4 can be arranged on the first housing 1, or on the second housing 2, or of course on the structural member outside the second housing 2. This application does not make specific limitations on this. As long as the light source assembly 4 can be stably installed to emit transcranial light for treatment towards the object's head. Preferably, the light source assembly 4 is arranged outside the second housing 2, so that the heat generated when the light source assembly 4 works has less influence on the cold air in the first cold air transmission cavity 3 and will not overly affect the temperature of the cold air, enabling the cold air to better cool the object's head in the accommodation cavity.

[0040] In order to enable the transcranial light emitted by the light source assembly 4 to pass through the housing and irradiate towards the object's head, those skilled in the art can set the material of part or the whole of each housing according to the installation position of the light source assembly 4. For example, when the light source assembly 4 is arranged outside the first housing 1 and inside the second housing 2, the above first housing 1 can be made of a light-transmitting material, so that the transcranial light emitted by the light source assembly 4 can pass through the first housing 1 and irradiate towards the object's head. Another example is that when the light source assembly 4 is arranged outside the second housing 2, both the first housing 1 and the second housing 2 can be made of light-transmitting materials, so that the transcranial light emitted by the light source assembly 4 can pass through the first housing 1 and the second housing 2 and irradiate towards the object's head. Another example is that when there is a light source assembly 4 at the position corresponding to the abutting member 5, the light-guiding part of the abutting member 5 can also be made of a light-transmitting material, so that the transcranial light emitted by the light source assembly 4 can pass through the light-guiding part of the abutting member 5 and irradiate towards the object's head. It can be understood that the parts of the above first housing 1, second housing 2 and abutting member 5 corresponding to the installation of the light source assembly 4 can be made of light-transmitting materials, and the parts not corresponding to the installation of the light source assembly 4 can not be made of light-transmitting materials, or can also be made of light-transmitting materials. As long as the purpose that the transcranial light emitted by the light source assembly 4 can irradiate towards the object's head can be achieved, this application does not make specific limitations on this.

[0041] The above abutting member 5 can be made of a material with good heat conduction performance, so as to effectively cool the abutting member 5 through the cold air in the second cold air transmission cavity 51, thereby achieving the purpose of quickly cooling the object's head through the abutting member 5.

[0042] The above abutting member 5 can be constructed into any shape and structure such as a plate-like structure or an arc-shaped structure. This application does not limit the specific structural form of the abutting member 5, as long as it can ensure the comfort when the object's head abuts.

[0043] In some embodiments, as Figures 4 to 6 shown, the above-mentioned abutting member 5 can be configured as a plate-like structure, a wavy arc structure, a structure of a plurality of spaced-apart plates, etc.; among them, Figure 4 the abutting member 5 shown in is configured as a plate-like structure, Figure 5 the abutting member 5 shown in is configured as a structure of a plurality of spaced-apart plates, Figure 6 the abutting member 5 shown in is configured as a wavy arc structure. Preferably, the side surface of the abutting member 5 facing the head of the object can be configured as an arc surface, and the arc surface is adapted to the outer contour shape of the head of the object, so that the abutting member 5 can contact the head of the object more comfortably and can increase the contact area with the head, thereby cooling the head of the object comfortably and effectively through the abutting member 5.

[0044] The size and quantity of the above-mentioned first air outlet holes 11 can be adjusted according to the demand for cold air to achieve the preset cooling effect. For example, in the case where a large amount of cold air is required in the second cold air transmission cavity 51, the air volume of the first air outlet holes 11 corresponding to the second cold air transmission cavity 51 can be increased to guide more cold air to be transmitted downward, such as increasing the size and / or quantity of the first air outlet holes 11 to provide more cold air for the second cold air transmission cavity 51.

[0045] The quantity of the above-mentioned first air outlet holes 11 can be multiple, and some of the multiple first air outlet holes 11 can be distributed on the first housing 1 along a preset distance to deliver the cold air evenly and quickly into the second cold air transmission cavity 51, and then cool the abutting member 5 and the head of the object in contact with the abutting member 5. Of course, in some embodiments, in addition to being provided corresponding to the second cold air transmission cavity 51, the first air outlet holes 11 can also be provided corresponding to the accommodation cavity, so that some of the cold air discharged from the first air outlet holes 11 can directly blow to the head of the object, thereby achieving the purpose of cooling the head of the object. The size of the above-mentioned preset distance can be determined according to actual use requirements, and the present application does not make any limitation in this regard.

[0046] In the present application, the cold air in the first cold air transmission cavity 3 can be delivered to the second cold air transmission cavity 51 through the first air outlet holes 11 on the first housing 1, and then the cold air can be directly blown to the abutting member 5. The cold air can reduce the temperature of the abutting member 5 to effectively cool the abutting member 5. The abutting member 5 separates the first housing 1 and part of the head of the object, preventing the head of the object from always abutting against the inner side surface of the first housing 1. By cooling the abutting member 5, the temperature of the area where the head of the object abuts against the abutting member 5 can be reduced, ensuring the comfort of the head, and the head of the object can be effectively cooled through the abutting member 5, avoiding the situation where the temperature of the head of the object is too high during treatment, reducing the risk of thermal injury, and improving the safety and comfort of the head of the object during the light treatment process.

[0047] In some embodiments, such as Figure 2 shown, the first housing 1 has a first area 12 that can abut against the object's head (an area that is relatively easy to abut against the object's head compared to other areas), and the abutting member 5 is provided corresponding to the first area 12. Exemplarily, the first area 12 can be provided at a position on the first housing 1 that is relatively lower and is easy to abut against the object's head. In this way, the first housing 1 abuts against the object's head through the first area 12, and the abutting member 5 can be provided corresponding to the first area 12. When cold air blows towards the abutting member 5 to reduce the temperature of the abutting member 5, it can effectively cool the area where the object's head abuts against the abutting member 5, ensuring the cooling efficiency and avoiding the occurrence of thermal damage.

[0048] In some embodiments, the above-mentioned first area 12 can be an annular area, which can circumferentially abut against the object's head. By providing the abutting member 5 on the first area 12, the object's head and the first housing 1 can be separated, and the abutting member 5 cooled by cold air can cool the object's head.

[0049] In some embodiments, at least part of the abutting member 5 is configured as an arc-shaped plate that fits the shape of the object's head.

[0050] In this way, the comfort of the abutment between the abutting member 5 and the object's head can be ensured by the arc-shaped plate, and the contact area between the two can also be increased, improving the cooling effect of the abutting member 5 on the head, ensuring the comfort when the head-mounted device is worn, and improving the adaptability of the abutting member 5 to the object's head. In addition, the arc-shaped plate will not have hard contact with the head and cause a pressing pain on the head. Therefore, the arc-shaped plate can not use a flexible material or a flexible layer can not be provided on the surface in contact with the head, and there is no need to use a flexible material or a flexible structure to ensure the comfort of contact with the head.

[0051] The above-mentioned arc-shaped plate can be specifically provided at a position on the object's head that is prone to thermal damage, so that the cold air in the first cold air transmission cavity 3 can be concentratedly blown towards the arc-shaped plate, thereby improving the cooling effect of the arc-shaped plate on the object's head.

[0052] Exemplarily, the above-mentioned abutting member 5 can include a plurality of arc-shaped plates. The plurality of arc-shaped plates can be evenly arranged around the object's head, or can be provided on the left and right sides of the object's head, or can be provided in the four regions of the front, back, left, and right of the object's head. The present application does not specifically limit the arrangement method of the plurality of arc-shaped plates, as long as it can effectively cool the object's head. Among them, when there are a plurality of the above-mentioned arc-shaped plates, the interval between each arc-shaped plate and the first housing 1 is configured as the above-mentioned second cold air transmission cavity 51.

[0053] The above-mentioned arc-shaped plate can be detachably installed on the inner side of the first housing 1, and the arrangement of the arc-shaped plate can be adaptively adjusted according to different arrangement modes of the light source assembly 4, the easy-to-attach positions of the head, the areas prone to high temperature, etc., so as to obtain a better effect of cooling the head while ensuring the comfort of the head during attachment. For example, in the scenario where the light source assembly 4 covers multiple brain regions of the object, there may be local high temperature in multiple regions of the relatively lower part of the first housing 1 that are prone to contact with the head. In this case, multiple arc-shaped plates can be arranged around the head of the object. Another example is that in the scenario where the light source assembly 4 is arranged corresponding to some brain regions, for example, the light source assembly 4 is arranged to only irradiate the left and right temporal lobes, and the occipital and frontal regions are not prone to high temperature, and the possibility of causing thermal damage to the head even when contacting the head is relatively small. In this case, the arc-shaped plates can be arranged corresponding to the left and right sides of the head of the object, and the arc-shaped plates can be not arranged in other regions, so as to achieve targeted comfort guarantee and effective cooling.

[0054] In some embodiments, as Figures 2 to 4 shown, the attachment member 5 is configured as an annular plate arranged around the head of the object, and the second cold air transmission cavity 51 is configured as an annular cavity.

[0055] In this way, the attachment member 5 configured as an annular plate can ensure the comfort of contact when the head is attached to any position, and can cool the head of the object circumferentially and evenly over a larger area when contacting, further improving the effect of cooling the head of the object, making the circumferential temperature of the head of the object uniform and improving the comfort.

[0056] Exemplarily, the cross-sectional shape of the attachment member 5 can be L-shaped. The L-shaped attachment member 5 has a vertical plate and a horizontal plate. The vertical plate is used to form the second cold air transmission cavity 51 between the attachment member 5 and the first housing 1, and the horizontal plate is used to connect the attachment member 5 to the first housing 1.

[0057] In some embodiments, as Figure 2 shown, the first housing 1 further has a second region 13 above the first region 12. An interval cavity is formed between the second region 13 and the head of the object. The interval cavity is a partial accommodation cavity, and the interval cavity is communicated with the second cold air transmission cavity 51. It can be understood that the interval cavity is a part of the accommodation cavity for accommodating the head of the object formed by the head-mounted device.

[0058] Thus, the cold air is first delivered from the first cold air transmission cavity 3 to the second cold air transmission cavity 51. After cooling the abutting member 5, it can also be delivered to the spacer cavity via the second cold air transmission cavity 51. Thereby, while ensuring the effect of cooling the object's head by the abutting member 5, the temperature of the spacer cavity can be further reduced, achieving a uniform cooling effect on all parts of the accommodation cavity, so that the temperature values at all parts in the accommodation cavity are within a preset range, to further ensure the comfort and safety of the object during the treatment process. In particular, when no first air outlet holes 11 are provided in the second region 13, or only a very small number of first air outlet holes 11 are provided, and the cold air is first guided to be delivered more downward from above the first cold air transmission cavity 3 to the second cold air transmission cavity 51, during the treatment process, when the head-mounted device is worn on the object's head, the air flow in the spacer cavity formed between the second region 13 and the object's head will slow down. As the treatment duration increases, the heat generated during the treatment process will also increase. When no first air outlet holes 11 are provided in the second region 13 or only a very small number of first air outlet holes 11 are provided, the temperature in the spacer cavity will rise and good heat dissipation cannot be achieved. Delivering part of the cold air in the second cold air transmission cavity 51 to the spacer cavity can further achieve a good heat dissipation effect on the spacer cavity, further ensuring the comfort and safety of the object during the treatment process.

[0059] The above-mentioned second region 13 can be understood as a region that is relatively unlikely to abut against the object's head compared to the first region 12 (during the transcranial light treatment process, the second region 13 may also abut against the object's head when the object's head makes large movements) or does not abut against the object's head.

[0060] In some embodiments, as Figure 2 and Figure 3 shown, an air outlet channel 52 is formed between the upper side of the abutting member 5 and the first housing 1. The air outlet channel 52 communicates the second cold air transmission cavity 51 with the accommodation cavity, specifically with the above-mentioned spacer cavity.

[0061] Thus, by providing the air outlet channel 52 on the upper side of the abutting member 5, the cold air can flow through the abutting member 5 and come into full contact with the abutting member 5, and then be delivered to the spacer cavity via the air outlet channel 52. While reducing the temperature in the spacer cavity, the cooling effect and cooling efficiency of the abutting member 5 are effectively ensured.

[0062] Specifically, the abutting member 5 can guide the cold air coming out of the first cold air transmission cavity 3 to be delivered upward, and then be delivered to the accommodation cavity via the air outlet channel 52. When the bottom of the abutting member 5 is hermetically connected to the first housing 1, the cold air in the second cold air transmission cavity 51 can come into full contact with the abutting member 5, thereby increasing the effect of the abutting member 5 in cooling the object's head.

[0063] The above-mentioned air outlet channel 52 can be arranged in a ring on the upper side of the abutting member 5 to discharge cold air in the circumferential direction of the object's head, achieving a better effect of cooling the object's head. Of course, the above-mentioned air outlet channel 52 can also be multiple, and multiple air outlet channels 52 are spaced apart on the upper side of the abutting member 5. The present application does not specifically limit the number and arrangement method of the air outlet channels 52, and the air outlet channels 52 can be set according to actual usage requirements.

[0064] In some embodiments, as Figures 4 to 6 shown, a support portion 54 is provided on the side of the abutting member 5 facing the first housing 1, and the support portion 54 abuts against the first housing 1.

[0065] In this way, the support portion 54 can play a role in stably supporting the abutting member 5, so that the abutting member 5 and the first housing 1 can maintain a relatively stable positional relationship, avoiding problems such as deformation of the abutting member 5 due to force, which affects the gas transmission in the second cold air transmission cavity 51 and the comfort of contact with the head, thereby achieving the purpose of ensuring the fluidity of the cold air in the second cold air transmission cavity 51.

[0066] The above-mentioned support portions 54 can be multiple, and multiple support portions 54 are spaced apart on the side of the abutting member 5 facing the first housing 1, so that the force on the support portions 54 is more uniform.

[0067] The above-mentioned support portion 54 and the abutting member 5 can be integrally formed to facilitate ensuring the structural relationship between the abutting member 5 and the support portion 54.

[0068] The above-mentioned support portion 54 can be arranged in a dislocation manner with the light source assembly 4, so that the transcranial light emitted by the light source assembly 4 can irradiate more towards the object's head, avoiding affecting the light power of the light source assembly 4 to ensure the treatment effect.

[0069] In some embodiments, as Figure 2 and Figure 6 shown, the abutting member 5 is provided with a second air outlet hole 53, and the first air outlet hole 11 is arranged in a dislocation manner with the second air outlet hole 53.

[0070] In this way, the cold air can be directly blown towards the object's head through the second air outlet hole 53 on the abutting member 5 to further reduce the temperature of the corresponding first area 12 of the object's head, improving the comfort and safety of the object. Moreover, the first air outlet hole 11 and the second air outlet hole 53 are arranged in a dislocation manner, which can avoid the cold air blown out from the first air outlet hole 11 being directly blown out from the second air outlet hole 53, resulting in an obvious cooling effect of the abutting member 5 due to the cold air not fully contacting the abutting member 5. In addition, the dislocation arrangement of the first air outlet hole 11 and the second air outlet hole 53 can also reduce the speed of the cold air, avoiding blowing directly on the head at a high speed and further improving the comfort.

[0071] The offset arrangement of the first air outlet hole 11 and the second air outlet hole 53 can enable the cold air discharged from the first air outlet hole 11 to directly blow towards the abutting member 5 first. The cold air first contacts the abutting member 5 to preferentially achieve direct cooling of the abutting member 5, and then is delivered from the offset second air outlet hole 53 to the accommodation cavity between the object's head and the first housing 1 to cool the head. In this way, it can be ensured that when the object's head abuts, what it contacts is the cooled abutting member 5, and thermal damage will not be caused during contact. Even when the object's head blocks the second air outlet hole 53 when the object's head abuts against the abutting member 5, the cold air can still be blown from the first air outlet hole 11 towards the abutting member 5, ensuring the effective cooling of the abutting member 5. Further, it is ensured that when the object's head abuts against the abutting member 5, what it always contacts is the cooled abutting member 5, and thermal damage to the object's head will not be caused due to the too high temperature of the abutting member 5, which can ensure the safety and comfort of the object's head during transcranial light therapy. Moreover, even when the object's head abuts against the abutting member 5 and the object's head blocks the second air outlet hole 53, the cold air discharged from the first air outlet hole 11 can still be delivered to the accommodation cavity through the air outlet channel 52. In this way, the cooling effect on the head can still be ensured.

[0072] In some other embodiments, the second air outlet hole 53 may not be provided on the abutting member 5. In this way, it can ensure the effect of fully cooling the abutting member 5 with the cold air in the second cold air transmission cavity 51, and further ensure the effect of cooling the object's head by the abutting member 5.

[0073] In some embodiments, both the second air outlet hole 53 and the first air outlet hole 11 are multiple. The multiple second air outlet holes 53 and the multiple first air outlet holes 11 are arranged in groups correspondingly. The number of the second air outlet holes 53 in the same group is less than the number of the first air outlet holes 11.

[0074] In this way, the transmission efficiency of the cold air from the first air outlet hole 11 to the second cold air transmission cavity 51 is greater than the transmission efficiency of the cold air from the second air outlet hole 53 to the accommodation cavity. Thus, the situation of too fast loss of the cold air in the second cold air transmission cavity 51 is avoided, and the cold air in the second cold air transmission cavity 51 can fully contact the abutting member 5.

[0075] Exemplarily, the number of the first air outlet holes 11 in each group can be 5, and the number of the second air outlet holes 53 can be 4. In this way, it can be ensured that when the first air outlet hole 11 and the second air outlet hole 53 have the same size, the amount of cold air delivered from the first cold air transmission cavity 3 to the second cold air transmission cavity 51 per unit time is always more than the amount of cold air delivered from the second cold air transmission cavity 51 to the accommodation cavity through the second air outlet hole 53, effectively avoiding the problem of rapid loss of the cold air in the second cold air transmission cavity 51, and further ensuring the effect of cooling the abutting member 5 with the cold air.

[0076] The first air outlet hole 11 and the second air outlet hole 53 in each of the above groups can be provided corresponding to a light source assembly 4, so as to ensure that there is corresponding cold air for cooling in the area irradiated by the transcranial light emitted by each light source assembly 4, further reducing the risk of thermal damage and specifically cooling the head of the subject.

[0077] In some embodiments, at least part of the light source assemblies 4 are provided corresponding to the abutting members 5. Specifically, it can be the light source assemblies 4 provided corresponding to the areas of the head where abutment is likely to occur. In this way, the area irradiated by this part of the light source assemblies 4 can directly contact and cool the head of the subject through the abutting members 5, avoiding the problem of excessive local temperature in the irradiated area. Moreover, the abutting members 5 can be used to isolate the light source assemblies 4 and the head of the subject as much as possible, thereby reducing the risk of thermal damage.

[0078] In some embodiments, the part of the abutting member 5 that can abut against the head of the subject is made of a light-transmitting rigid material.

[0079] In this way, the transcranial light emitted by the light source assembly 4 can pass through the light-transmitting abutting member 5 and reach the head of the subject, ensuring the comfort of the head when abutting against the abutting member 5, being able to reduce the temperature of the head while abutting, and improving the treatment effect of the head-mounted device, enabling more of the transcranial light emitted by the light source assembly 4 to pass through the skull and enter the cerebral cortex. Moreover, the rigid material abutting member 5 can prevent the problem that the abutting member 5 deforms due to the extrusion force of the head and affects the flow of the cold air in the second cold air transmission cavity 51.

[0080] In addition, in order to ensure the comfort of abutment, the spacer in the prior art is generally made of a flexible and light-transmitting material. For example, a light-transmitting silicone material is used. The spacer adapted to the transcranial light irradiation area made of this material (which needs to be designed into various complex structural shapes according to the transcranial light irradiation area) has complex processes, high costs, is prone to deterioration and color change (the light guiding effect will be reduced after color change), is prone to generating peculiar smells, etc., and has a short service life. In a preferred embodiment, at least part of the abutting member 5 is configured as an arc-shaped plate adapted to the shape of the head, and the part of the arc-shaped plate that abuts against the head of the subject is made of a light-transmitting rigid material. The arc-shaped plate made of the rigid material can also ensure the comfort when the head abuts. When designing, there is no need to design various complex structural shapes to avoid the transcranial light irradiation area, and there is no need to consider the influence of force deformation on the flow of the cold air in the second cold air transmission cavity 51. Moreover, it is simple to manufacture and has low costs. For example, it can be made of the same rigid light-transmitting material as that used for the first housing 1. Compared with the light-transmitting flexible material, it is not prone to deterioration and color change, does not generate peculiar smells after being used for a period of time, and has a long service life.

[0081] In some other embodiments, a flexible layer may also be provided on the side of the abutting member 5 facing away from the first housing 1. The flexible layer can further improve the comfort of the contact between the abutting member 5 and the object's head. The flexible layer can be made of a light-transmitting material so that the transcranial light emitted by the light source assembly 4 can pass through the flexible layer and irradiate the object's head.

[0082] In some other embodiments, a part of the abutting member 5 may also be made of a flexible material or configured as a flexible structure to improve the comfort of contact with the object's head.

[0083] Exemplarily, the area of the abutting member 5 that can closely abut against the object's head is made of a hard material, and the area where the abutting member 5 abuts against the object's head more loosely or not fully abuts may also be made of other materials.

[0084] In some embodiments, the bottom of the abutting member 5 is sealingly connected to the first housing 1; or, the abutting member 5 includes a bottom plate connected to the first housing 1, and a third air outlet hole may be provided on the bottom plate.

[0085] The bottom of the abutting member 5 can be sealingly connected to the first housing 1. Specifically, the abutting member 5 can guide all the cold air coming out of the first cold air transmission cavity 3 to be delivered upward, or guide a part of the cold air to be delivered upward, and a part of the cold air can be delivered to the accommodation cavity from other directions. In the case where the bottom of the abutting member 5 is sealingly connected to the first housing 1, the cold air can stay in the second cold air transmission cavity 51 for a longer time, slow down the outward discharge of the cold air in the second cold air transmission cavity 51, and increase the efficiency of cooling the abutting member 5.

[0086] In some embodiments, the abutting member 5 may include a bottom plate connected to the first housing 1, and a third air outlet hole may be provided on the bottom plate. In this way, in the case where the third air outlet hole is provided on the bottom plate, the object's head area and / or neck area corresponding to the lower part of the first area 12 can be cooled through the third air outlet hole, increasing the contact area between the cold air and the object's head and neck.

[0087] In this way, cold air can be delivered to the vicinity of the object's head and neck through the third air outlet hole. Moreover, the opening position of the third air outlet hole can not only guide part of the cold air to be delivered to the position corresponding to the lower part of the object's head and neck, so that the cold air delivered to the lower part cools the object's head and neck, and can circulate well with the air in the accommodation cavity (or the outside), but also can avoid the discharged cold air from directly blowing on the object's head (such as the ear), achieving the purpose of effectively cooling the object's head while improving the comfort of the object's head.

[0088] The number of the above-mentioned third air outlet holes should not be too many. On the basis of ensuring that the cold air in the second cold air transmission cavity 51 will not quickly escape, more cold air in the second cold air transmission cavity 51 can be guided into the accommodation cavity, so as to evenly cool the entire accommodation cavity.

[0089] The air outlet area of the third air outlet hole is smaller than that of the air outlet channel 52, so that more cold air in the second cold air transmission cavity 51 can be discharged from the air outlet channel 52.

[0090] In some embodiments, as Figure 2 shown, at least a part of the first air outlet holes 11 are arranged corresponding to the second area 13, so that a part of the cold air in the first cold air transmission cavity 3 can enter the accommodation cavity through the first air outlet holes 11 located in the second area 13. In this way, it is possible to achieve the formation of convection of the gas discharged from the first air outlet holes 11 located in the second area 13 and the gas discharged from the air outlet channel 52 in the accommodation cavity, so as to further cool the accommodation cavity through the convective cold air, effectively improving the effect of cooling the head of the object.

[0091] In some other embodiments, the first air outlet holes 11 may not be provided in the second area 13. The cold air in the first cold air transmission cavity 3 will naturally be transmitted from top to bottom. Since the second area 13 of the first housing 1 is relatively far from the head of the object, the temperature of the second area 13 is relatively low itself. Therefore, even if the first air outlet holes 11 are not provided in the second area 13, it can be ensured that the temperature of the second area 13 will not be too high.

[0092] In some embodiments, the second area 13 may include a first sub-area and a second sub-area arranged from top to bottom. The first air outlet holes 11 may be opened in the first sub-area, and the first air outlet holes 11 may not be provided in the second sub-area. When the head-mounted device is worn on the head, the gas flowability in the accommodation cavity will become poor. In particular, the gas flowability in the accommodation cavity relatively far from the external environment (such as the spacer cavity formed between the second area 13 and the head of the object) will become poor. As the treatment duration or the optical power increases, the heat generated during the treatment will also increase accordingly, and the cold air discharged from the air outlet channel 52 is gradually heated during the rising process, and the rising speed may gradually slow down. Therefore, the discharged cold air may not be able to further cool the first sub-area and the spacer cavity formed between this area and the head. In particular, when the optical power emitted by the light source assembly 4 is relatively high, the cold air in the first cold air transmission cavity 3 cannot achieve the expected cooling effect on it. At this time, opening a small number of the first air outlet holes 11 in the first sub-area can avoid the above problems. The cold air discharged from the first air outlet holes 11 can further cool the first sub-area and the spacer cavity formed between this area and the head, avoiding local high temperature and keeping the temperature deviation between each part in the accommodation cavity within a preset range, that is, the temperature of each part in the accommodation cavity can be kept in a balanced state.

[0093] In addition, the cold air discharged from the first air outlet hole 11 on the first sub-region can also effectively convect with the cold air discharged from the air outlet channel 52 of the abutting member 5 in the second sub-region, so that the temperature of the second sub-region can be effectively reduced. Moreover, by not providing the first air outlet hole 11 on the second sub-region as described above, more cold air in the first cold air transmission cavity 3 can flow to the first air outlet hole 11 correspondingly provided with the abutting member 5, so that more cold air is discharged through the first air outlet hole 11 into the second cold air transmission cavity 51 to achieve a better cooling effect for the abutting member 5.

[0094] In some other embodiments, the first air outlet hole 11 may also be provided on the second sub-region, but the air outlet area of the first air outlet hole 11 on the second sub-region should be much smaller than that of the first air outlet hole 11 on the first sub-region, so that more cold air can be delivered into the second cold air transmission cavity 51 to achieve a better cooling effect for the abutting member 5.

[0095] In some embodiments, part of the above light source assembly 4 may be correspondingly arranged in the second region 13, and the light source assembly 4 arranged corresponding to the second region 13 and the first air outlet hole 11 opened in the second region 13 may be correspondingly arranged to preferably reduce the temperature of the area directly irradiated by the light source assembly 4.

[0096] In some embodiments, the number of the first air outlet holes 11 provided on the second region 13 should not be too large, so as to guide more cold air in the first cold air transmission cavity 3 to enter the second cold air transmission cavity 51, thereby more effectively cooling the abutting member 5.

[0097] In some embodiments, the transcranial light modulation device is used to treat brain function-related diseases. In particular, it is used to treat neurodegenerative diseases such as Alzheimer's disease, mild cognitive impairment, dementia, etc., and can also be used to treat mental diseases such as depression, autism, and bipolar disorder.

[0098] It can be understood that when using the above 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 disease type, degree of illness, etc. This application does not make specific limitations on this. Among them, the irradiation parameters can include average light power density, pulse frequency, etc.

[0099] In some preferred embodiments, the above transcranial light modulation device is used to treat patients with Alzheimer's disease (AD). In addition to the decline in cognitive ability, such patients are also accompanied by emotional and mental problems, such as emotional restlessness, anxiety, irritability, insensitivity to temperature, etc. For such patients, a head-mounted device with a loose design (with a certain margin of movement when the head is worn on the head-mounted device) is required, and a relatively high light power density is used to achieve effective treatment. Therefore, when the transcranial light modulation device is used to treat such special patients with Alzheimer's disease (AD), there are high requirements for the temperature and comfort during the treatment process. The solution of the present application can ensure the comfort and safety when the patient's head is in contact with the head-mounted device, and at the same time, it can also achieve uniform temperature distribution in each area of the accommodation cavity, achieve a better cooling effect, improve the comfort of patients with Alzheimer's disease (AD) during the treatment process, and enhance the compliance of patients during the treatment process, which can greatly extend the single treatment duration, and then determine a good treatment effect.
