Description

Technical Field

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

[0002] Existing transcranial light regulation devices reduce the high temperature caused by light irradiation by introducing cold air into the accommodation cavity formed by the headgear to accommodate the patient's head. The existing design is to set air holes at corresponding positions on the first shell inside the headgear for each position of the head, and the cold air blows directly to the object's head through each air hole, thereby achieving cooling for the object's head, that is, the cold air enters the accommodation cavity through the air hole units at each position from top to bottom to cool the patient's head. However, in the existing design, the cold air in the transcranial light regulation device is naturally delivered to the accommodation cavity through the air hole units at each position from top to bottom, and the cold air transmission path design is not reasonable enough. During the actual treatment process, the temperature in the accommodation cavity is unevenly distributed, and there is a problem of too high local temperature. Especially in the area relatively close to the object's head, the temperature in this area will be higher than that in the area far from the object's head, which will affect the comfort of the patient during the treatment process and the light therapy effect.

The light-emitting component is arranged on the outside of the first shell and is used to emit transcranial light to the object's head. The guiding component is arranged on the inside of the first shell and at least part of it is correspondingly arranged with the second area. The guiding component has an exhaust port communicating with the cooling channel, and the opening of the exhaust port faces the first spacer cavity.

[0005] In some embodiments, the first area is provided with a first air outlet hole communicating with the cooling channel to discharge part of the cold air in the cooling channel to the first spacer cavity.

[0007] In some embodiments, the second spacer cavity is configured as an annular cavity surrounding the head of the object, and the exhaust port is configured as an annular through groove surrounding the head of the object.

[0008] In some embodiments, a second air outlet hole is provided in the second region of the first housing, and the exhaust port of the guiding member communicates with the cooling channel through the second air outlet hole.

[0009] In some embodiments, a first air outlet hole communicating with the cooling channel is provided in the first region to discharge part of the cold air in the cooling channel to the first spacer cavity, and the total air outlet area of the first air outlet hole is smaller than the total air outlet area of the second air outlet hole.

[0010] In some embodiments, a third air outlet hole is provided on the guiding member, and the opening of the third air outlet hole faces the head of the object.

[0016] In some embodiments, the transcranial light modulation device is used to treat at least one of neurodegenerative diseases and mental diseases.

[0017] Compared with the prior art, the beneficial effects of the embodiments of the present application are as follows: Due to reasons such as the cold air transmission direction and the distance from the object's head, the temperature in the upper-to-lower regions of the accommodation cavity is uneven, especially in the relatively lower regions where the temperature is prone to being too high.

[0028] 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 those, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0029] 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.

[0030] The embodiments of this application provide a transcranial light modulation device. As Figures 1 to 4As shown in the figure, the transcranial light regulation device includes a head-mounted device, a light-emitting component 4, and a guiding component 5. The head-mounted device includes a first housing 1 and a second housing 2 covering the outside of the first housing 1. A cooling channel 3 is formed between the first housing 1 and the second housing 2. The cooling channel 3 is used to accommodate the cold air generated by the cold air manufacturing device. The first housing 1 has a first area 11 and a second area 12 arranged from top to bottom. A first spacer cavity 13 is formed between the first area 11 and the object's head. The light-emitting component 4 is arranged on the outside of the first housing 1 and is used to emit transcranial light to the object's head, such as near-infrared light that can penetrate the skull and act on the cerebral cortex. The guiding component 5 is arranged on the inside of the first housing 1 and at least part of it is correspondingly arranged with the second area 12. The guiding component 5 has an exhaust port 51 communicating with the cooling channel 3, and the opening of the exhaust port 51 faces the first spacer cavity 13.

[0031] The above-mentioned head-mounted device forms a receiving cavity for accommodating the object's head. During light therapy, it can be worn on the object's head, and the object's head is placed inside the first housing 1. A first spacer cavity 13 is formed between the first area 11 of the first housing 1 and the object's head. It can be understood that the first spacer cavity 13 is part of the receiving cavity. The relatively upper part in the receiving cavity (such as the first spacer cavity 13 or the part in the first spacer cavity 13 relatively close to the top of the head) can be understood as the part far from the object's head, and the relatively lower part in the receiving cavity can be understood as the part close to the object's head. Since the cold air will naturally be delivered downward, due to reasons such as less delivered amount, unreasonable design of the transmission path resulting in a higher temperature of the cold air delivered to the lower part, and different distances from the object's head, the temperature of the part of the area close to the object's head will be higher than that of the part of the area far from the object's head, and there may be a problem of uneven temperature in the receiving cavity.

[0032] In this application, by transmitting the cold air in the cooling channel 3 through the guiding component 5, the cold air can be guided from bottom to top into the first spacer cavity 13, so that the cold air can first blow to the part of the area close to the object's head, and then blow to the part of the area far from the object's head, that is, first cool the part of the area close to the object's head, and then cool the part of the area far from the object's head, which can make the temperature of the part of the area close to the object's head and the temperature of the part of the area far from the object's head balanced, achieving the purpose that the temperature of each area in the receiving cavity can be evenly distributed. It can be understood that the temperature deviation of each area in the receiving cavity is within a preset range to achieve a better cooling effect.

[0033] The exhaust port 51 of the above-mentioned guiding component 5 can be formed independently by the guiding component 5, or can be formed by the cooperation of the guiding component 5 and other components, such as formed by the cooperation of the guiding component 5 and the first housing 1. This application does not make specific limitations on this. As long as the exhaust port 51 can communicate with the cooling channel 3 to discharge the cold air inside.

[0034] After wearing the head-mounted device, the above-mentioned object head can also play a role in guiding the air flow, so as to facilitate guiding the cold air discharged from the exhaust port 51 to directly flow into the first spacer cavity 13.

[0035] Specifically, the cold air entering the cooling channel 3 through the air inlet 21 is supplied by a cold air manufacturing device, such as a refrigerator, or can also be supplied by other cold air manufacturing devices, such as a fan. The present application does not make specific limitations thereto.

[0036] In some embodiments, the above-mentioned cold air manufacturing device can be arranged outside the head-mounted device or inside the cooling channel 3. Exemplarily, when the cold air manufacturing device is arranged outside the head-mounted device, an air inlet 21 can be provided on the second housing 2, and the cold air manufacturing device supplies cold air to the cooling channel 3 through the air inlet 21.

[0037] In the following, the present application takes the second housing 2 being provided with an air inlet 21 for supplying cold air to the cooling channel 3 as an example to illustrate the technical solution of the present application. However, the present application is not limited thereto. Those skilled in the art can set the installation position of the cold air manufacturing device, whether to open the air inlet 21, and the quantity, installation position, size, etc. of the air inlet 21 according to actual needs, as long as there is cold air for cooling in the cooling channel 3. The present application does not make specific limitations thereto. For example, the air inlet 21 opened on the second housing 2 can be arranged at the upper part of the second housing 2 or on the side of the second housing 2. Also, for example, in some embodiments, a plurality of air inlets 21 can be respectively opened at the upper part and the side of the second housing 2.

[0038] In some embodiments, as Figures 1 to 3 shown, the air inlet 21 is arranged at the upper part of the second housing 2, so that the cold air in the cooling channel 3 can flow from top to bottom by using the property that cold air naturally delivers from top to bottom.

[0039] In some embodiments, a support structure can 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, avoiding deformation of the first housing 1 and the second housing 2 due to force and causing problems affecting the structure of the cooling channel 3, thereby achieving the purpose of ensuring the air circulation of the cold air in the cooling channel 3.

[0040] It should be noted that the "cool air" in this application means a gas with a temperature lower than the temperature in the accommodation cavity during transcranial light therapy, and does not limit the cool air in the cooling channel 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. For example, the temperature in the accommodation cavity during transcranial light therapy can reach 45°C or even about 55°C, while the temperature of the cool air in the cooling channel 3 can be set between 25°C and 30°C.

[0041] The above-mentioned light-emitting component 4 can be arranged on the first housing 1, or on the second housing 2, and of course, it can also be arranged on the structural member outside the second housing 2. This application does not make specific limitations on this. As long as the light-emitting component 4 can be stably installed and the transcranial light can be emitted towards the object's head. Preferably, the light-emitting component 4 is arranged outside the second housing 2. In this way, the heat generated when the light-emitting component 4 works has less influence on the cool air in the cooling channel 3 and will not overly affect the temperature of the cool air, enabling the cool air to better cool the object's head in the accommodation cavity.

[0042] In order to enable the transcranial light emitted by the light-emitting component 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-emitting component 4. For example, when the light-emitting component 4 is arranged outside the first housing 1 and inside the second housing 2, the first housing 1 can be made of a light-transmitting material, so that the transcranial light emitted by the light-emitting component 4 can pass through the first housing 1 and irradiate towards the object's head. Another example is that when the light-emitting component 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-emitting component 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 a light-emitting component 4 is arranged at the position corresponding to the guiding component 5, the light-guiding part of the guiding component 5 can also be made of a light-transmitting material, so that the transcranial light emitted by the light-emitting component 4 can pass through the light-guiding part of the guiding component 5 and irradiate towards the object's head. It can be understood that the parts of the first housing 1, the second housing 2, and the guiding component 5 corresponding to the installation of the light-emitting component 4 can be made of light-transmitting materials, and the parts not corresponding to the installation of the light-emitting component 4 can either 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-emitting component 4 can irradiate towards the object's head can be achieved. This application does not make specific limitations on this.

[0043] The above-mentioned guiding component 5 can be constructed into a tubular structure, a plate-like structure, an arc-shaped structure or any other structure of any shape. This application does not limit the specific structural form of the guiding component 5, as long as it can guide the cool air in the cooling channel 3 to be discharged towards the first spacer cavity 13 through the exhaust port 51.

[0044] For example, when the above-mentioned guiding member 5 is configured as a tubular structure, the guiding member 5 can be configured as a circular tube or other tubes to realize the circulation of the cold air in the cooling channel 3 through the tubular structure. Another example is that when the above-mentioned guiding member 5 is configured as an arc structure, the outer wall surface and the inner wall surface of the guiding member 5 can both be configured as arc surfaces, so as to be adapted to the first housing 1 through the arc-shaped outer wall surface and to the outer contour of the object's head through the arc-shaped inner wall surface.

[0045] The size and quantity of the above-mentioned exhaust port 51 can be adjusted according to the demand for cold air in the first spacer cavity 13. For example, when a large amount of cold air is required in the first spacer cavity 13, more cold air can be provided for the first spacer cavity 13 by increasing the quantity of the exhaust ports 51 and enlarging the size of the exhaust ports 51.

[0046] The above-mentioned exhaust port 51 can be arranged at the junction of the first area 11 and the second area 12, or can be arranged in the second area 12. The opening of the exhaust port 51 faces the first spacer cavity 13, so that the cold air discharged from the exhaust port 51 can directly enter the first spacer cavity 13. In some other embodiments, the exhaust port 51 can also directly extend into the first spacer cavity 13 to directly cool the first spacer cavity 13 through the cold air.

[0047] Due to reasons such as the direction of cold air transmission and the different distances from the object's head, the temperature in the area from top to bottom in the accommodation cavity is uneven in hot and cold. In particular, the relatively lower area is prone to excessive temperature. In the present application, through the connection between the cooling channel 3 formed between the first housing 1 and the second housing 2 and the exhaust port 51 of the guiding member 5, it is possible to guide more cold air downward through the exhaust port 51 of the guiding member 5 and supply the delivered cold air to the first spacer cavity 13 formed between the first area 11 and the object's head. The above structural design enables the cold air to first cool the relatively lower area from top to bottom and then be guided by the exhaust port 51 to blow upward into the relatively upper first spacer cavity 13, achieving the purpose of uniform temperature distribution in each area of the accommodation cavity, realizing a better cooling effect, and improving the comfort of the patient during the treatment process.

[0048] In particular, when no air outlet holes are provided in the first area 11 or only a very small number of air outlet holes are provided, 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 first area 11 and the object's head will slow down. When no air outlet holes or only a very small number of air outlet holes are provided in the first area 11, the temperature in the spacer cavity will rise and good heat dissipation cannot be achieved. By using the exhaust port 51 of the guiding member 5 to supply the delivered cold air to the first spacer cavity 13, a further good heat dissipation effect on the first spacer cavity 13 can be realized, further ensuring the comfort and safety of the object during the treatment process.

[0049] In some embodiments, especially for the scenario of multi-brain region irradiation, such as the corresponding positions of the frontal lobe, temporal lobe, and occipital lobe are evenly provided with light-emitting components. When irradiating multiple brain regions with a relatively high light power, the temperature in the accommodation cavity will be relatively high, and there are likely to be regions with large temperature differences. For example, the temperature of the region close to the subject's head is much higher than that of the region far from the subject's head, and the temperature will gradually rise along the direction of cold air delivery. This will lead to a serious problem of uneven temperature in the accommodation cavity, affecting the comfort of the patient during the treatment process and further affecting the light treatment effect. The structural design of the present application can, in particular, better cool each region in the accommodation cavity during multi-brain region irradiation, enabling the cold air to first blow to some regions with higher temperatures and then to some regions with relatively lower temperatures, so that the temperatures of each region in the accommodation cavity are balanced, better cooling the subject's head in the multi-brain region irradiation scenario and improving the comfort of the subject during the treatment process.

[0050] In some embodiments, such as Figure 3 and Figure 4 shown, the first region 11 may be provided with a first air outlet 14 communicating with the cooling channel 3 to discharge some of the cold air in the cooling channel 3 to the first spacer cavity 13.

[0051] In this way, it can be realized that the gas discharged from the first air outlet 14 and the gas discharged from the exhaust port 51 of the guiding component 5 form convection in the first spacer cavity 13, so as to further cool the first spacer cavity 13 through the convective cold air, effectively improving the cooling effect.

[0052] In some other embodiments, the first air outlet 14 may not be provided in the above-mentioned first region 11. Since the cold air in the cooling channel 3 will naturally transmit from top to bottom, the cold air first cools the first region 11, and the first region 11 of the first housing 1 is relatively far from the subject's head, and the temperature of the first region 11 will be relatively low. Therefore, even if the first air outlet 14 is not provided in the first region 11, it can be ensured that the temperature of the first region 11 will not be too high.

[0053] In some embodiments, the above-mentioned first region 11 may include a first sub-region and a second sub-region arranged from top to bottom. The first air outlet 14 may be opened in the first sub-region, while no first air outlet 14 is provided in the second sub-region. When the head-mounted device is worn on the head, the gas flowability in the accommodation cavity becomes poor. In particular, the gas flowability in the first spacer cavity 13, which is relatively far from the external environment, becomes poor. As the treatment duration or light power increases, the heat generated during the treatment also increases accordingly. Moreover, the cold air discharged from the exhaust port 51 is gradually heated during the rising process, and the rising speed may gradually slow down. Therefore, the cold air discharged from the exhaust port 51 may not be able to further cool the first sub-region and the spacer cavity formed between this region and the head, and the cold air in the cooling channel 3 also cannot achieve the expected cooling effect on it. At this time, opening a small number of first air outlets 14 in the first sub-region can avoid the above problems. The cold air discharged from the first air outlets 14 can further cool the first sub-region and the spacer cavity formed between this region and the head, avoid the occurrence of local high temperature, and keep the temperature deviation between each part in the accommodation cavity within a preset range, that is, the temperature at each part in the accommodation cavity can be maintained in a balanced state.

[0054] In addition, the cold air discharged from the first air outlets 14 in the first sub-region can also form an effective convection with the cold air discharged from the exhaust port 51 of the guiding component 5 in the second sub-region, so that the temperature of the second sub-region can be effectively reduced. The non-setting of the first air outlets 14 in the above-mentioned second sub-region can enable more cold air in the cooling channel 3 to flow to the exhaust port 51 of the guiding component 5, so that more cold air is discharged into the first spacer cavity 13 through the exhaust port 51.

[0055] The setting height of the above-mentioned first air outlets 14 can be such that the flow direction of the cold air discharged therefrom is towards the first spacer cavity 13, so as to avoid the problem of non-convection with the cold air discharged from the exhaust port 51 in the first spacer cavity 13.

[0056] In some embodiments, a small number of first air outlets 14 may also be provided in the second sub-region. Specifically, the air outlet area of the first air outlets 14 in the second sub-region should be much smaller than the air outlet area of the first air outlets 14 in the first sub-region, so that more cold air in the cooling channel 3 can flow to the exhaust port 51 of the guiding component 5.

[0057] The above-mentioned light-emitting component 4 may be partially arranged corresponding to the first region 11. The light-emitting component 4 arranged corresponding to the first region 11 and the first air outlets 14 opened in the first region 11 can be arranged corresponding to each other, so as to preferably reduce the temperature of the region directly irradiated by the light-emitting component 4.

[0058] In some embodiments, such as Figure 3 and Figure 4As shown, a second spacing cavity 6 is formed between the guiding component 5 and the first housing 1, and the second spacing cavity 6 communicates with the exhaust port 51 of the guiding component 5.

[0059] In this way, the cold air discharged from the cooling channel 3 can pass through the second spacing cavity 6 and then be discharged through the exhaust port 51. The cold air in the second spacing cavity 6 can reduce the temperature of the guiding component 5. Specifically, the second region 12 is relatively lower than the first region 11 and is likely to come into contact with the object's head. If the temperature is too high, it will affect the comfort of the object during transcranial light therapy, and even cause thermal damage when coming into contact with the head. When the guiding component 5 is arranged in the second region 12, the above design can improve the comfort and safety when the object's head approaches or even fits with the guiding component 5.

[0060] The exhaust port 51 can be located at the upper part of the second spacing cavity 6, so that the cold air in the second spacing cavity 6 can flow upward to the exhaust port 51.

[0061] The guiding component 5 can be made of a material with good thermal conductivity to effectively cool the guiding component 5 through the cold air in the second spacing cavity 6.

[0062] In some embodiments, a flexible layer can be provided on the side of the guiding component 5 facing away from the first housing 1, and the flexible layer can improve the comfort of the contact between the guiding component 5 and the object's head. In other embodiments, the guiding component 5 can also be made of a flexible material or configured as a flexible structure to improve the comfort of the contact with the object's head.

[0063] In some embodiments, such as Figure 3 and Figure 4 shown, the second spacing cavity 6 is configured as an annular cavity surrounding the object's head, and the exhaust port 51 is configured as an annular through groove surrounding the object's head.

[0064] In this way, the cold air can be discharged in the circumferential direction of the object's head through the exhaust port 51 configured as an annular through groove, achieving a better effect of cooling the object's head.

[0065] Preferably, the guiding component 5 is configured as a plate shape and is arranged around the inner side of the first housing 1. Since the plate-shaped guiding component 5 has a curvature adapted to the shape of the head, even if the guiding component 5 is not made of a flexible material or provided with a flexible layer, the comfort can be ensured when the head approaches or contacts the guiding component 5.

[0066] In some embodiments, such as Figure 3 shown, a second air outlet hole 15 is provided on the second region 12 of the first housing 1, and the exhaust port 51 of the guiding component 5 communicates with the cooling channel 3 through the second air outlet hole 15.

[0067] In this way, the cold air in the cooling channel 3 can directly flow to the exhaust port 51 through the second air outlet hole 15.

[0068] The number of the above-mentioned second air outlet holes 15 can be multiple, and the multiple second air outlet holes 15 can be arranged from top to bottom, so that the cold air in the cooling channel 3 can quickly flow to the exhaust port 51 from multiple directions.

[0069] The above-mentioned light-emitting component 4 can be partially arranged corresponding to the second area 12, and the second air outlet hole 15 can be arranged opposite to the light-emitting component 4 arranged corresponding to the second area 12, so as to preferably reduce the temperature of the area directly irradiated by the light-emitting component 4.

[0070] The shape of the above-mentioned second air outlet hole 15 can be circular, strip-shaped, etc. The present application does not make specific limitations on this, and the shape, number, etc. of the second air outlet hole 15 can be set according to requirements. The shapes of the multiple second air outlet holes 15 can be the same or different, and the present application does not make specific limitations on this either.

[0071] In some preferred embodiments, the air outlet area of the above-mentioned second air outlet hole 15 can be adaptively increased, so that the cold air in the cooling channel 3 can flow to the exhaust port 51 more and faster. For example, the air outlet area of the second air outlet hole 15 can be increased by means such as setting the number of the second air outlet holes 15 to be greater than the number of the first air outlet holes 14 and the aperture of the second air outlet hole 15 to be greater than the aperture of the first air outlet hole 14, so as to guide more cold air in the cooling channel 3 to be delivered to the second interval cavity 6, and then enter the first interval cavity 13, realizing a better and more uniform cooling effect.

[0072] In some embodiments, the first area 11 can be provided with a first air outlet hole 14 communicating with the cooling channel 3 to discharge part of the cold air in the cooling channel 3 to the first interval cavity 13, and the total air outlet area of the first air outlet hole 14 is smaller than the total air outlet area of the second air outlet hole 15.

[0073] In this way, by making the total air outlet area of the first air outlet hole 14 smaller than the total air outlet area of the second air outlet hole 15, while discharging part of the cold air in the cooling channel 3 to the first interval cavity 13, it can be ensured that more cold air is delivered downward to the second area 12, that is, a small amount of cold air can be discharged through the first air outlet hole 14, while a large amount of cold air can be discharged through the second air outlet hole 15 to the exhaust port 51 of the guiding component 5, thereby ensuring the cooling effect of the guiding component 5 and the first interval cavity 13.

[0074] The fact that the total air outlet area of the above-mentioned first air outlet hole 14 is smaller than the total air outlet area of the second air outlet hole 15 can be realized by adjusting parameters such as the sizes and numbers of the first air outlet hole 14 and the second air outlet hole 15, so that the total air output volume of the first air outlet hole 14 can be smaller than the total air output volume of the second air outlet hole 15.

[0075] In some embodiments, such as Figure 3 and Figure 4 shown, the guiding member 5 is provided with a third air outlet hole 52, and the opening of the third air outlet hole 52 is arranged towards the object's head.

[0076] In this way, part of the cold air in the second interval cavity 6 can be blown towards the object's head through the third air outlet hole 52, further increasing the effect of cooling the object's head. Especially for the case where the object's head does not completely abut against the guiding member 5, it can better cool the object's head.

[0077] In some embodiments, the above-mentioned guiding member 5 can be configured as an L-shaped plate. The L-shaped plate includes a vertical plate and a horizontal plate. The vertical plate is spaced from the inner side of the first inner shell to form a second interval cavity 6, and the horizontal plate is used to connect with the first shell 1.

[0078] It can be understood that the second area 12 is an area that is more likely to abut against the object's head compared to other areas. In some embodiments, at least part of the guiding member 5 is correspondingly arranged with the second area 12. Therefore, the guiding member 5 is also likely to abut against the object's head. In order to ensure the safety and comfort of the object's head during transcranial light therapy, preferably, the guiding member 5 is cooled to ensure that no thermal damage occurs when the object's head abuts against the guiding member 5.

[0079] In some preferred embodiments, the third air outlet hole 52 and the second air outlet hole 15 can be arranged in a staggered manner. The staggered arrangement of the third air outlet hole 52 and the second air outlet hole 15 can make the cold air discharged from the second air outlet hole 15 directly blow towards the guiding member 5 first, giving priority to directly cooling the guiding member 5. Then, part of the cold air is delivered from the staggered third air outlet hole 52 to the accommodation cavity between the object's head and the first shell 1 to cool the head. In this way, it can be ensured that the guiding member 5 that the object's head contacts when abutting is the cooled guiding member 5, and no scalding will be caused. Even when the object's head blocks the third air outlet hole 52 when the object's head abuts against the guiding member 5, the cold air can still be blown from the second air outlet hole 15 towards the guiding member 5, ensuring the effective cooling of the guiding member 5. In this way, it can be ensured that the guiding member 5 that the object's head contacts when abutting against the guiding member 5 is always the cooled guiding member 5, and no thermal damage to the object's head will be caused due to the too high temperature of the guiding member 5, and the safety and comfort of the object's head during transcranial light therapy can be ensured. And the above-mentioned staggered arrangement of the second air outlet hole 15 and the third air outlet hole 52 can reduce the speed of the cold air and avoid the cold air directly blowing towards the object's head at a high speed, further improving the comfort.

[0080] In addition, since a second spacer cavity 6 and an exhaust port 51 are formed between the guiding member 5 and the first housing 1, even when the object's head abuts against the guiding member 5 and the object's head blocks the third air outlet 52, the cold air can enter the accommodation cavity from the exhaust port 51 to cool the head, preventing local high temperature from occurring and still ensuring that the temperatures at various locations in the accommodation cavity are uniform, thus ensuring the comfort of the object during the treatment process.

[0081] In some embodiments, the second region 12 is a region that can abut against the object's head. The first region 11 above the second region 12 can be understood as a region that is relatively less likely to abut against the object's head (but may also abut during large movements of the object's head during transcranial light therapy) or does not abut against the object's head, so as to form a first spacer cavity 13 between it and the object's head.

[0082] In this way, the guiding member 5 can cool the region that does not or is difficult to abut against the object's head, that is, the first region 11, and can directly contact and cool the object's head through the guiding member 5, improving the comfort of the object.

[0083] It can be understood that in some other embodiments, the above-mentioned second region 12 can also be a region that does not abut against the object's head. It is relatively lower than the first region 11, so that the cold air can be blown upward from the bottom to the first spacer cavity 13 through the guiding member 5 to achieve a uniform cooling effect.

[0084] In some embodiments, such as Figure 3 and Figure 4 As shown, the bottom of the guiding member 5 is hermetically connected to the first housing 1; alternatively, the guiding member 5 includes a bottom plate 53 connected to the first housing 1, and a fourth air outlet may be provided on the bottom plate 53. Specifically, the guiding member 5 can guide all the cold air coming out of the cooling channel 3 upward, or guide a part of the cold air upward and a part of the cold air can be delivered to the accommodation cavity from other directions, such as from the side or below of the guiding member 5 to the accommodation cavity. When the bottom of the guiding member 5 is hermetically connected to the first housing 1, more cold air in the cooling channel 3 can be discharged from the exhaust port 51, increasing the efficiency of cooling the first spacer cavity 13. When the fourth air outlet is provided on the bottom plate 53, the object's head region and / or neck region corresponding to below the second region 12 can be cooled through the fourth air outlet, increasing the contact area between the cold air and the object's head and neck.

[0085] In some embodiments, the air outlet area of the above-mentioned fourth air outlet is smaller than the air outlet area of the exhaust port 51, so that more cold air in the second spacer cavity 6 can be discharged from the exhaust port 51.

[0086] In some embodiments, such asFigures 2 to 4 As shown, the first housing 1 further has a third region 16 located below the second region 12. A bottom of the third region 16 is provided with a fifth air outlet hole 17 communicating with the cooling channel 3.

[0087] In this way, cold air can be delivered to the head and neck of the object near the third region 16 through the fifth air outlet hole 17. Moreover, the opening position of the fifth air outlet hole 17 can not only guide part of the cold air to be delivered to the position corresponding to the head and / or neck of the object below, so that the cold air delivered below cools the head and neck of the object, but also can circulate well with the air in the accommodation cavity (or the outside), and can also prevent the discharged cold air from directly blowing towards the head of the object (such as the ear), achieving the purpose of effectively cooling the head and neck of the object while improving the comfort of the head of the object.

[0088] The above-mentioned third region 16 can be understood as the region corresponding to the ear and near the ear contour of the object's head. There is less hair on the object's head corresponding to the third region 16, and it is not easy to accumulate heat. Moreover, the lower part of the head-mounted device is provided with an opening, and the third region 16 is closer to the external environment than the first region 11 and the second region 12. Therefore, by setting the fifth air outlet hole 17, the requirement of cooling the object's head can be met.

[0089] The number of the above-mentioned fifth air outlet holes 17 and the first air outlet holes 14 should not be too many, so as to guide more cold air in the cooling channel 3 to enter the second region 12, thereby cooling the accommodation cavity part corresponding to the second region 12 and the first spacer cavity 13 more effectively. With the cooperation of the setting of the third region 16, the uniform cooling of the entire accommodation cavity is further realized.

[0090] In some embodiments, the number of the above-mentioned fifth air outlet holes 17 can be multiple, and the openings of the multiple fifth air outlet holes 17 can all be set downward.

[0091] In some embodiments, as Figure 1 shown, there are multiple light-emitting components 4. The multiple light-emitting components 4 are respectively arranged corresponding to the first region 11 and the second region 12 of the first housing 1, and the multiple light-emitting components 4 are arranged around the object's head in cooperation. In this way, transcranial light can be emitted to the object's head through the multiple light-emitting components 4 arranged around the object's head, achieving the purpose of fully treating multiple brain regions of the object's head.

[0092] In some embodiments, the transcranial light regulation 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, etc.

[0093] It is understandable that when using the above transcranial light regulation 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 in this regard. Among them, the irradiation parameters can include average optical power density, pulse frequency, etc.

[0094] In some preferred embodiments, the above transcranial light regulation device is used to treat patients with Alzheimer's disease (AD). In addition to showing a decline in cognitive ability, such patients are also accompanied by emotional and mental problems, such as emotional restlessness, anxiety, being easily irritated, and insensitivity to temperature. Moreover, such patients need to use a relatively high optical power density to achieve effective treatment. Therefore, when the transcranial light regulation device is used to treat such special patients with Alzheimer's disease (AD), the temperature requirements during the treatment process are very high. The solution of this application can 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 thus determine a good treatment effect.
