[0029] An embodiment of the present utility model provides a multi-light source coupling device for a near-infrared brain function imaging device. As Figures 1 to 3 shown, the multi-light source coupling device includes a coupling component 2 and a plurality of light source components 1. The light source component 1 is used to emit near-infrared light. As Figures 1 to 4 shown, the coupling component 2 includes a housing 21 and a light guide body 22 disposed in the housing 21. The plurality of light source components 1 are respectively installed on the housing 21. The light guide body 22 is configured as a multi-branch structure. The light guide body 22 includes a light-emitting branch 26 and a plurality of light-incident branches 27 respectively connected to the light-emitting branch 26. The light-incident branches 27 are correspondingly arranged with the light source components 1. Each light-incident branch 27 is respectively used to transmit the near-infrared light to be coupled emitted by the light source component 1 to the light-emitting branch 26, so as to emit the coupled near-infrared light outward through the light-emitting branch 26.

[0030] Optionally, the light source assembly 1 can be understood as a device capable of emitting near-infrared light, such as any light-emitting optical component like an LED lamp, a laser, etc. Specifically, the light source assembly 1 can be an emission probe that uses an LED lamp to emit near-infrared light. At this time, the light source assembly 1 can be an emission probe that can be used in combination with other devices, or an emission probe that is not used in combination with other devices. This application does not make specific limitations on this, and the type of the light source assembly 1 can be selected according to the requirements of the usage scenario.

[0031] Exemplarily, as Figures 1 to 3 shown, Figures 1 to 3 the specific form of the light source assembly 1 shown in Figure 5 is an emission probe; as Figure 5 shown,

[0032] the specific form of the light source assembly 1 shown in Figures 1 to 3 is an LED lamp. The number of the above-mentioned light source assemblies 1 can be determined according to the needs of the operator, the requirements of near-infrared brain functional imaging detection, etc. Exemplarily, the number of the light source assemblies 1 can be 3, 5, or 7, etc.

[0033] Optionally, the above-mentioned light guide body 22 can achieve light guiding based on structural design or based on material design. In the case where the light guide body 22 achieves light guiding based on structural design, the light guide body 22 can have a light guiding cavity, and the near-infrared light is exported through the reflection of the light guiding cavity; in the case where the light guide body 22 achieves light guiding based on material design, the light guide body 22 is made of a light guiding material. At this time, the light guide body 22 can be constructed as a solid structure. Specifically, it can be combined with Figure 4 , Figure 4 where the light guide body 22 shown is a solid structure.

[0034] The process of the above-mentioned light guide body 22 coupling near-infrared light can be understood as the process of conducting the near-infrared light entering multiple light incident branches 27 to the same light output branch 26 to achieve the coupling effect.

[0035] Optionally, the above-mentioned light source assembly 1 can include a buckle 12, and the buckle 12 is detachably connected to the housing 21 to facilitate the disassembly and assembly of the light source assembly 1 on the housing 21, and the installation stability of the light source assembly 1 can be ensured through the buckle 12.

[0036] The present application uses the light-outgoing branch 26 of the light guide 22 and multiple light-incoming branches 27 respectively connected to the light-outgoing branches 26 to achieve the coupling and outward emission of light emitted by multiple light source assemblies 1, thereby effectively improving the light output power. In particular, for scenarios where near-infrared light needs to be transmitted through a longer optical fiber, by coupling the near-infrared light emitted by multiple light source assemblies 1, the optical power of the coupled near-infrared light emitted outward can be improved to meet the requirements of near-infrared brain function imaging detection with high reliability.

[0037] In some embodiments, Figures 1 to 3 As shown, the multi-light source coupling device further includes a light output structure 3, which is arranged corresponding to the light output end of the light output branch 26 to output the near-infrared light emitted through the light output branch 26 to the head of the object to be detected.

[0038] In this way, the near-infrared light emitted by the light output branch 26 can be stably output outward through the light output structure 3, which can effectively increase the output distance of the near-infrared light, so that the multi-light source coupling device can be applied to a variety of usage scenarios.

[0039] Optionally, the light output structure 3 may be constructed as a long strip light transmission structure, such as an optical fiber, which can effectively output the near infrared light to the head of the object to be detected.

[0040] Optionally, the light output structure 3 can be connected to the housing 21 in a detachable manner, such as snap-on, threaded, etc., and the present application does not make any specific limitation on this, as long as the light output structure 3 and the light output end of the light output branch 26 are arranged correspondingly.

[0041] In some embodiments, Figure 4 As shown, a plurality of light-incoming branches 27 are respectively connected to one point on the light-outgoing branch 26 .

[0042] In this way, the near-infrared lights derived from the plurality of light-incoming branches 27 can be converged to one point on the light-outgoing branch 26 , so as to increase the optical power of the near-infrared lights output by the light-outgoing branch 26 .

[0043] Optionally, the light-emitting branch 26 has a light-incoming end opposite to the light-emitting end thereof, and a plurality of light-incoming branches 27 may be respectively connected to the light-incoming ends of the light-emitting branch 26 .

[0044] In some embodiments, Figure 4 As shown, the incoming light branch 27 is along the first length direction (eg Figure 4 The light-emitting branch 26 extends along the second length direction (as shown in the first direction in FIG. Figure 4 The first length direction and the second length direction are extended (as shown in the second direction in FIG), and the angle between the first length direction and the second length direction is in the range of 120° to 135°.

[0045] It should be noted that Figure 4 the first length direction in Figure 4 (i.e., the first direction in Figure 4 ) is only exemplary. In practical applications, the number of the first directions can be set according to the number of the light incident branches 27, and the embodiments of the present disclosure do not limit the number of the first length directions.

[0046] In this way, the range of the included angle between the above-mentioned first length direction and the second length direction can ensure that more near-infrared light emitted from the light incident branches 27 is transmitted to the light output branch 26, thereby improving the optical power of the near-infrared light output by the light output branch 26.

[0047] Optionally, the above-mentioned multiple light incident branches 27 can be evenly arranged around the second length direction. For example, when the number of the light incident branches 27 is 3, the included angle between adjacent light incident branches 27 can be 120 degrees.

[0048] In some embodiments, as shown in Figure 2 and Figure 3 , the housing 21 has a receiving cavity for receiving the light guide 22, and the shape of the receiving cavity is adapted to the shape of the light guide 22.

[0049] In this way, the light guide 22 can be accommodated by the receiving cavity whose shape is adapted to the shape of the light guide 22, improving the structural compactness of the multi-light source coupling device and ensuring the stability of the near-infrared light during transmission in the light guide 22.

[0050] Optionally, a light-shielding layer can be formed on the inner wall of the receiving cavity to reduce the light transmission loss of the light guide 22 in the receiving cavity.

[0051] In some embodiments, as shown in Figure 2 , the light-emitting end of the light source assembly 1 is attached to one end of the light incident branch 27; and / or, the light-emitting end of the light output branch 26 is attached to the light output structure 3.

[0052] The above structure can reduce the transmission loss of the near-infrared light, so that the near-infrared light can be transmitted more between the light source assembly 1, the light guide 22 and the light output structure 3.

[0053] Optionally, a bonding layer can be provided between the light-emitting end of the light source assembly 1 and one end of the light incident branch 27 to ensure the stable attachment of the light source assembly 1 and the light guide 22.

[0054] Optionally, a bonding layer can be provided between the light-emitting end of the light output branch 26 and the light output structure 3 to ensure the stable attachment of the light output structure 3 and the light guide 22.

[0055] In some embodiments, as shown in Figure 2 and Figure 3As shown, the light source assembly 1 includes a light emitting part 11 for emitting near-infrared light. Both the light emitting part 11 and the light incident branch 27 of the light guide 22 are configured as columns, and the diameter of the light emitting part 11 is less than or equal to the diameter of the light incident branch 27 of the light guide 22, so that more of the near-infrared light emitted by the light emitting part 11 of the light source assembly 1 can be guided into the light guide 22, thereby further improving the light transmission efficiency. By reducing the loss of near-infrared light during transmission, it is ensured that the near-infrared light is captured and received to the maximum extent, and further improving the light guiding efficiency of the light guide 22 of the multi-light source coupling device.

[0056] Optionally, the light emitting branch 26 of the light guide 22 may be configured as a column. The diameters of the light incident branch 27 and the light emitting branch 26 may be the same or different, and the present application does not make specific limitations thereon. The diameter range of the light incident branch 27 and the light emitting branch 26 may be from 3 mm to 3.4 mm. Preferably, the diameters of the light incident branch 27 and the light emitting branch 26 may both be 3.2 mm.

[0057] Optionally, the diameter range of the light emitting part 11 may be from 2.6 mm to 3 mm. Preferably, the diameters of the light incident branch 27 and the light emitting branch 26 may both be 2.8 mm.

[0058] Optionally, the light output structure 3 may be configured as a column, and the light emitting branch 26 of the light guide 22 may be less than or equal to the diameter of the light output structure 3. The diameter range of the light output structure 3 may be from 3 mm to 3.4 mm. Preferably, the diameter of the light output structure 3 may be 3.2 mm.

[0059] In some embodiments, the light source assembly 1 further includes an elastic member (not shown in the figure). The elastic member acts on the light emitting part 11 to apply a force to the light emitting part 11 to make it abut against the light guide 22.

[0060] In this way, it can be ensured that the light emitting part 11 of the light source assembly 1 can stably abut against the light guide 22, and it is ensured that the near-infrared light emitted by the light emitting part 11 can be more stably transmitted into the light guide 22.

[0061] Optionally, the elastic member may be disposed on the side of the light emitting part 11 away from the light guide 22 to stably apply a force to the light emitting part 11. Among them, the elastic member may specifically be a compression spring.

[0062] In some embodiments, such as Figures 1 to 3As shown in the figure, the housing 21 includes an upper housing 23, a lower housing 24, and a connecting member 25. The upper housing 23 and the lower housing 24 cooperate to form a receiving cavity. A plurality of light source assemblies 1 are all installed on the upper housing 23. The lower housing 24 is connected to the lower part of the upper housing 23. The connecting member 25 is used to detachably connect the upper housing 23 and the lower housing 24. Through the structure of the housing 21 described above, the light guide 22 and the light source assembly 1 can be stably installed, so that the near-infrared light emitted by the light source assembly 1 can be stably transmitted to the light guide 22, effectively avoiding the situation that the light source assembly 1 falls off during the use of the multi-light-source coupling device by the operator, and greatly improving the reliability and firmness of the multi-light-source coupling device.

[0063] Optionally, the connecting member 25 can be specifically a component such as a flange, which can be detachably connected to the upper housing 23 and the lower housing 24; among them, the detachable connection can be different connection methods such as threaded connection, snap connection, or plug connection. For example, the three can be stably connected by passing bolts through the connecting member 25, the upper housing 23, and the lower housing 24.

[0064] Optionally, the connecting member 25 can be detachably connected to the light output structure 3, such as by threaded connection.

[0065] The embodiment of the present invention also provides a near-infrared brain function imaging device. The near-infrared brain function imaging device includes the above multi-light-source coupling device for the near-infrared brain function imaging device.

[0066] The near-infrared brain function imaging device using the above multi-light-source coupling device can couple and emit the light emitted by a plurality of light source assemblies 1 through the light output branch 26 of the light guide 22 and a plurality of light input branches 27 respectively connected to the light output branch 26, effectively improving the light output power. Especially for the scenario where near-infrared light needs to be transmitted through a long optical fiber, by coupling the near-infrared light emitted by a plurality of light source assemblies 1, the light power of the coupled near-infrared light emitted outward can be increased to meet the requirements of near-infrared brain function imaging detection, and the reliability is high.

[0067] In some embodiments, the near-infrared brain function imaging device can be used in combination with at least one of a TMS device and an MRI device. Among them, the TMS device is a transcranial magnetic stimulation device, and the MRI device is a nuclear magnetic resonance imaging device.

[0068] Thus, when the near-infrared brain functional imaging device is used in combination with a TMS device or an MRI device, it can simultaneously meet the requirements of using the TMS device (or MRI device) for treatment (or detection) and performing near-infrared brain functional imaging detection, so that in the combined use scenario, it will neither affect the normal use of the TMS device (or MRI device), nor can it obtain near-infrared data that meets the requirements, so that the near-infrared data can be used to evaluate the treatment effect of the TMS device, the detection effect of the MRI device, and study the treatment mechanism of TMS on diseases, etc.
