[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] Unless otherwise defined, technical terms or scientific terms used in the present application shall be understood as the usual meaning understood by those of ordinary skill in the art to which the present application belongs. The terms "first", "second" and similar words used in the present application do not represent any order, number or importance, but are only used to distinguish different components. The terms "include" or "contain" and similar words mean that the elements or objects before the words cover the elements or objects listed after the words and their equivalents, without excluding other elements or objects. The terms "connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "up", "down", "left", "right" and the like are only used to represent relative positional relationships, which may change accordingly when the absolute position of the described object changes.

[0024] Specifically, the near-infrared brain function imaging device comprises at least one pair of emitting probes and receiving probes, wherein each pair of emitting probes and receiving probes can form a detection channel, each probe can be assembled to a head cap worn on the head of a subject, the emitting probe is used for emitting near-infrared light to the cerebral cortex, and the receiving probe is used for collecting near-infrared light emitted from the head without being absorbed by the brain tissue. The near-infrared light emitted by the light source can be transmitted to the emitting probe through the optical fiber cable, or the light source can be directly installed on the emitting probe without the need for transmission through the optical fiber, and the receiving probe can send the optical signal back to the main machine for processing through the optical fiber cable. The near-infrared brain function imaging device comprises a plurality of emitting probes and receiving probes for simultaneously collecting signals of a plurality of brain regions. Generally, the more the number of probes, the more high-end the device, and the more brain regions that can be covered. A high-end near-infrared brain function imaging device can have dozens or even hundreds of probes.

[0025] In some scenarios, the user will not use all the transmitting probes and receiving probes for data acquisition, and sometimes part of the transmitting probes and receiving probes will be selected for detection according to different scenes and tasks. At this time, the redundant idle probes, cables and the like are hung or scattered on the equipment or the periphery. In particular, the redundant idle receiving probes will receive ambient light during the operation of the equipment, and return the collected ambient light signals to the equipment host, thereby interfering with the data collected by other normal channels.

[0026] To solve the above technical problems, the utility model embodiment provides a protection assembly for near-infrared brain function imaging equipment, wherein the near-infrared brain function imaging equipment at least includes a pair of transmitting probes and receiving probes. Wherein, the transmitting probes are used for emitting near-infrared light to the head of the object, and the receiving probes are used for receiving the near-infrared light from the head of the object which is not absorbed by the brain tissue and transmitting to the host of the equipment, so as to detect the concentration change of oxyhemoglobin and deoxyhemoglobin in the human tissue to reflect the brain activity degree, etc., thereby reflecting the brain function related activities such as memory, thinking, specific cognition and emotion.

[0027] As shown in Figure 1 and Figure 2 , the protection assembly of the embodiment at least includes a receiving probe light shielding sleeve 1, and the receiving probe light shielding sleeve 1 is connected with the receiving probe 3 to at least wrap the receiving end of the receiving probe 3 and limit the receiving probe 3 from receiving external light. Wherein, the external light can include ambient light or light projected or reflected by other light sources, etc.

[0028] During the use of the near-infrared brain function imaging equipment, the receiving probe 3 in the idle state can be equipped with the receiving probe light shielding sleeve 1. The protection assembly of the embodiment can avoid the interference of the near-infrared brain function imaging equipment caused by the idle receiving probe 3 receiving external light to the data collected by other normal channels, thereby improving the accuracy of data acquisition. Specifically, the probe light shielding sleeve 1 can be constructed in any shape, such as a cylindrical structure, a cuboid structure, etc., as long as it can be adapted to the receiving probe 3 and can be connected with it in a detachable manner, so as to facilitate the disassembly and assembly during use.

[0029] In some embodiments, the material color, structure design and the like of the receiving probe light shielding sleeve 1 can be adjusted to prevent the external ambient light from entering the receiving probe 3, which is not limited in the application.

[0030] In some embodiments, the material of the receiving probe light shielding sleeve 1 can be a light shielding material, which can be a silicone or similar material, and the color can be black. In this way, not only the light shielding effect can be achieved, but also the flexible material can protect the receiving end of the probe, avoiding hard contact with the receiving end and causing damage.

[0031] Alternatively, in some embodiments, the outer and / or inner surfaces of the receiving probe light shield 1 are coated with a layer of light-shielding material to prevent external light from passing through the light shield and entering the receiving end of the probe.

[0032] like Figure 1 As shown, in some embodiments, the light-shielding sleeve 1 of the receiving probe can be constructed as a cylindrical structure with one end open and the other end closed. When a receiving probe 3 is idle, the light-shielding sleeve 1 can be directly placed on the receiving end of the receiving probe 3 to prevent external light from affecting the idle receiving probe 3; when the idle receiving probe 3 needs to be used, the light-shielding sleeve 1 can be directly removed.

[0033] Furthermore, in some embodiments, the end face of the closed end of the receiving probe light shield 1 protrudes outward to form a relief cavity 10. Specifically, the receiving end of the receiving probe 3 may have a filter or other components, such as a coating. By setting the relief cavity 10, the end face of the closed end of the receiving probe light shield 1 can be prevented from touching the relief port, thereby damaging the filter or other components and affecting the measurement data.

[0034] Of course, the structure of the light-shielding sleeve 1 of the receiving probe in this embodiment is not limited to the above-mentioned cylindrical structure. Other structural forms can also be adopted, as long as it can ensure that the receiving end of the receiving probe 3 can block the receiving end from receiving external light.

[0035] In some embodiments, the protective component further includes a transmitter probe light shield (not shown in the figure), which can be connected to the transmitter probe (not shown in the figure) to at least cover the transmitter end of the transmitter probe, thereby protecting the transmitter end of the transmitter probe and improving its service life.

[0036] That is, the transmitting probe and receiving probe 3 of the near-infrared brain functional imaging device can each be equipped with a light-shielding sleeve. When the device leaves the factory, each transmitting probe and each receiving probe 3 is equipped with a light-shielding sleeve. Specifically, the light-shielding sleeve of the transmitting probe can also be constructed in any shape, such as a cylindrical structure, a cuboid structure, etc., as long as it can be adapted to the transmitting probe and can be detachably connected to it for easy disassembly and assembly during use.

[0037] Specifically, the structural design, materials used, and color of the light-shielding sleeve for the transmitting probe can be the same as or different from those for the light-shielding sleeve 1 for the receiving probe, and this application does not impose specific limitations on this. For example, since the idle transmitting probe will not enter the working state when the equipment is working, or it will not be affected by the surrounding ambient light, it will not affect the detection data. Therefore, the light-shielding sleeve for the transmitting probe does not need to be made of a light-blocking material.

[0038] like Figure 4As shown, in some embodiments, the near-infrared brain function imaging device further comprises a cable rack 5, a host computer 4 and cables 7, the transmission probe and the receiving probe 3 are connected to the host computer 4 through the cables 7 respectively, the transmission probe and the receiving probe 3 are installed on a headgear worn on the head of the subject 6 (not shown in the figure), and at least part of the cables 7 can be arranged on the cable rack 5 to comb and fix the cables 7. The protection assembly further comprises a storage member 2 for storing the cables 7 and / or the probes that fall on the cable rack 5.

[0039] It should be noted that the cable 7 connecting the receiving probe 3 and the host computer 4 is an optical fiber cable, and the cable connecting the transmission probe can be an optical fiber cable or a common cable. The storage member 2 of the present embodiment can store not only optical fiber cables but also common cables 7.

[0040] By storing the falling cables 7 and / or probes through the storage member 2, the appearance of the entire imaging device can be improved, and the falling cables 7 and / or probes can be prevented from being damaged. Specifically, the storage member 2 can be configured as a storage bag, a storage box or any other shape as long as it has a storage function.

[0041] In some embodiments, the storage member 2 can be arranged on the cable rack 5, thereby facilitating the storage of the storage member 2. The storage member 2 is detachably arranged on the cable rack 5 and can be detached at any time for replacement or cleaning. In other embodiments, the storage member 2 can also be fixed on the cable rack 5. The present application does not make specific limitations on the structure of the storage member 2 fixed on the cable rack 5, for example, it can be tied on the cable rack 5 by a rope, and the position fixed on the cable rack 5 can be changed as needed.

[0042] Preferably, the storage member 2 is arranged on the cable rack 5 at a position relatively far away from the host computer 4. Specifically, in order to better comb the cables, the cables 7 are generally arranged to extend to the headgear in a direction away from the host computer 4 along the length of the cable rack 5. The storage member 2 is arranged at a position on the cable rack 5 away from the host computer 4, so that the arrangement position of the storage member 2 is closer to the position of the headgear (that is, closer to the positions of the transmission probe and the receiving probe 3). When storing, the storage member 2 can avoid excessive bending of the optical fiber in the direction of the host computer 4, thereby improving the service life of the optical fiber.

[0043] Preferably, the material of the storage member 2 is a soft material such as cloth, etc. The soft storage member 2 can avoid friction with the cables 7 or the probes, thereby preventing damage to the cables 7 or the probes.

[0044] In addition, the color of the storage member 2 can be black or other colors that can block light, thereby further preventing external light from entering the storage member 2.

[0045] Or also can be, the outer peripheral wall and / or inner peripheral wall of the receiving member 2 is coated with a layer of light shielding material, respectively, by the light shielding material on the surface to prevent external light into the receiving member 2. Or, the receiving member 2 can be configured as a multi-layer structure, the inner side of the receiving member 2 (may be the inner layer) is configured as a light absorption structure, in order to be beautiful, the outer layer structure can be set to other colors or materials, but also can realize the blocking of external light into the receiving member 2. It can be understood that those skilled in the art can design various implementation manners according to the demand of blocking ambient light into the receiving member 2, and the present application does not make specific limitation.

[0046] As shown in Figure 3 some embodiments, the receiving member 2 can be a receiving bag with a bag opening tightening belt 21, and the material of the receiving bag can be selected from wear-resistant materials. The hanging cable 7 and the probe can be placed in the receiving bag, and then the bag opening of the receiving bag is tightened to prevent other sundries from falling into the receiving bag. At the same time, the bag opening can be tightened to bind the cable frame 5, which is convenient to use.

[0047] Of course, the structure of the receiving member 2 of the present application is not limited to the receiving bag structure, but also can be a receiving box structure, as long as it can receive the hanging cable 7 or the probe.

[0048] In some embodiments, the receiving member 2 is provided with a receiving space for receiving the receiving probe light shielding sleeve 1 and the transmitting probe light shielding sleeve.

[0049] When the structures of the receiving probe light shielding sleeve 1 and the transmitting probe light shielding sleeve are different, two receiving spaces can be provided on the receiving member 2. One of the receiving spaces is used for placing the receiving probe light shielding sleeve 1, and the other receiving space is used for placing the transmitting probe light shielding sleeve, so as to facilitate classification and storage, and facilitate the identification of the staff.

[0050] When the structure of the receiving member 2 is a receiving bag, the receiving space for receiving the receiving probe light shielding sleeve 1 and the transmitting probe light shielding sleeve can be an outer bag or an inner bag structure sewn on the receiving bag.

[0051] In some embodiments, the receiving member 2 has at least a first receiving cavity (not shown in the figure) and a second receiving cavity (not shown in the figure), the first receiving cavity is used for placing the receiving probe 3, and the second receiving cavity is used for placing the transmitting probe.

[0052] The first receiving cavity and the second receiving cavity can be two independent receiving cavities, and the receiving probe 3 and the transmitting probe can be received by setting two independent receiving cavities, which can facilitate the user to take.
