Description

Technical Field

[0001] This application relates to the field of near-infrared brain functional imaging technology, and in particular to a head-mounted near-infrared brain functional imaging device and system. Background Technology

[0002] In existing technologies, both the main unit and hub of a head-mounted near-infrared brain functional imaging device are worn on the head. The main unit is typically worn at the back of the head (occipital region), and the hub simply serves to manage the cables. The light sources emitting near-infrared light are located in each emitting probe, and each light source is connected to a driver in the main unit via a cable. The driver chip controls the driver to turn the light source on and off. Obviously, as the number of light sources increases, so does the number of cables connecting the light sources to the main unit. With a large number of light sources, there is a problem of multiple cables running from the main unit to the hub. The weight of these numerous cables is considerable, causing discomfort to the subject and making it difficult for them to cooperate. Utility Model Content

This system enables the driver located in the host to be electrically connected to multiple switching components via a first cable, eliminating the need for separate cables for each driver and light source. This effectively reduces the cable weight between the host and the light source control components, thereby reducing excessive pressure on the head from the cables.

[0004] This application provides a head-mounted near-infrared brain functional imaging device, comprising: A headgear, worn on the head, is equipped with multiple light sources that emit near-infrared light toward the head; A main unit, which is mounted on a headgear, includes an electrically connected driver and a first control element; A light source control assembly is disposed on the headgear. The light source control assembly includes multiple switches, each switch being electrically connected to a corresponding light source. A driver is electrically connected to each of the multiple switches via a first cable. A first control element is electrically connected to each of the multiple switches, and the first control element is used to control the corresponding light source to be in an illuminateable state via the driver, and to control the switches to make the corresponding light source in an illuminated state.

[0006] In some embodiments, the switching element and the light source element are arranged in a one-to-one correspondence.

[0007] In some embodiments, there are multiple drivers, and the drivers, switches, and light sources are respectively provided in a one-to-one correspondence, and the multiple drivers are all electrically connected to the corresponding switches through the first cable.

[0008] In some embodiments, there are multiple light source control components, and the light source elements are divided into multiple groups according to the different light source control components. The driver is electrically connected to the switching element of each light source control component. The first control element is also used to simultaneously control the light source elements of different groups to be in the lighting state through the driver and the switching element of each light source control component.

[0009] In some embodiments, the first control element is used to control the driver and the switch to illuminate the plurality of light sources in a time-division manner.

[0010] In some embodiments, there are multiple drivers, each of which is electrically connected to at least one of the multiple switching elements, so as to simultaneously drive the light source element electrically connected to the switching element through the multiple drivers.

[0011] In some embodiments, the plurality of switches are electrically connected to at least one driver, such that the driver controls the corresponding plurality of light sources to be in an illuminated state through the plurality of switches.

[0013] In some embodiments, the head-mounted near-infrared brain functional imaging device further includes a power supply component, which is electrically connected to at least a first control element within the host to supply power to the first control element, and the power supply component is not disposed on the headgear.

[0014] This application also provides a head-mounted near-infrared brain functional imaging system, which includes the head-mounted near-infrared brain functional imaging device described in any of the above embodiments, and further includes a host computer. The host computer is communicatively connected to the first control element, and the first control element is used to receive a lighting command sent by the host computer and control the plurality of light sources to be in a lighting state according to the lighting command.

The light source control component includes multiple switches that are electrically connected to light sources respectively. The driver located in the main unit can be electrically connected to the multiple switches respectively through a first cable. That is, the switches of the light source control component and the driver located in the main unit can be connected by a single cable, eliminating the need to set up a separate cable for each driver and light source. This reduces the number of cables between the main unit and the light source control component. In other words, the connection between the driver and the switches of the light source control component can be realized through the first cable, and the corresponding light source can be controlled by the switches. This effectively reduces the weight of the cables between the main unit and the light source control component, thereby reducing excessive pressure on the head from the cables and improving the wearing comfort of the head.

It should also be understood that terms defined in general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] This application provides a head-mounted near-infrared brain functional imaging device. For example... Figure 1 and Figure 2As shown, the head-mounted near-infrared brain functional imaging device includes a headgear 1, a main unit 2, and a light source control assembly 3. The headgear 1 is worn on the head and is equipped with multiple light sources 11, which emit near-infrared light towards the head. The main unit 2 is mounted on the headgear 1 and includes a driver 21 and a first control element 22 electrically connected to each other. The light source control assembly 3 is also mounted on the headgear 1 and includes multiple switches 31, each electrically connected to a corresponding light source 11. The driver 21 is electrically connected to each of the multiple switches 31 via a first cable 4. The first control element 22 is electrically connected to each of the multiple switches 31, and is used to control the corresponding light source 11 to be in an illuminated state via the driver 21, and to control the switches 31 to illuminate the corresponding light source 11. Here, "multiple light sources 11" can be understood as two or more light sources 11; the term "multiple" in the following text refers to two or more light sources, which will not be elaborated further.

[0025] It is understood that the headgear 1 may be equipped with probes 12, such as transmitting probes and receiving probes. The transmitting probes and receiving probes are spaced apart on the headgear 1 to form a large number of signal acquisition channels, thereby meeting the needs of multi-brain region detection of the subject's head. The aforementioned light source 11 that emits near-infrared light may be set inside the corresponding transmitting probe, such as the light source 11 being set one-to-one with the transmitting probe, to emit near-infrared light towards the head.

[0026] After receiving a first control command from the first control element 22, the aforementioned driver 21 can output electrical energy to the light source 11, enabling the light source 11 to enter a light-up state. The aforementioned light-up state can be understood as the ability to selectively keep the light source 11 in a lit state or a extinguished state, that is, the light source 11 can be in a lit state when the switch 31 is open, and in a non-light-emitting state, i.e., an extinguished state, when the switch 31 is closed.

[0027] The aforementioned multiple switches 31 can be directly electrically connected to the first control element 22, or they can be electrically connected to the first control element 22 through other modules, such as multiple switches 31 being electrically connected to the first control element 22 through the second control element 32 described below. When multiple switches 31 can be directly electrically connected to the first control element 22, each switch 31 can be configured with a module capable of communicating with the first control element 22, or each switch 31 can be electrically connected to the first control element 22 via a cable. This application does not impose specific limitations on this, as long as the stability of the electrical connection between the multiple switches 31 and the first control element 22 can be guaranteed.

[0028] The number of drivers 21 can be one or more. Preferably, providing independent drivers 21 for each switch 31 and light source 11 can ensure the stability of the electrical power supplied to the light source 11, thereby ensuring the reliability of the acquired near-infrared brain function data.

[0029] The aforementioned light source control component 3 can be one or more. When there are multiple light source control components 3, each switch 31 of the multiple light source control components 3 can be electrically connected to the driver 21 in the host 2, realizing the configuration of one host 2 and multiple light source control components 3. That is, the driver 21 in one host 2 can be electrically connected to the switch 31 of multiple light source control components 3 respectively.

[0030] It is understood that the first cable 4 may include at least a positive wire core and a negative wire core capable of forming a loop, so as to ensure an effective electrical connection between the driver 21 and the plurality of switches 31.

[0031] Specifically, the first control element 22 can control each light source 11 to light up sequentially in a preset order, or it can control multiple light sources 11 to light up simultaneously. The specific design can be tailored to the needs of collecting near-infrared brain function data.

[0032] During the operation of the head-mounted near-infrared brain functional imaging device, the first control element 22 can send a first control command to the driver 21. Upon receiving the first control command, the driver 21 can output electrical energy to the corresponding light source 11, making the corresponding light source 11 available for illumination. Furthermore, the first control element 22 can send a second control command to open the switch 31. Based on this second control command, the switch 31 will be in the open state, thus allowing the light source 11 to directly enter the illumination state after it is already available for illumination, thereby providing power to the corresponding light source 11 and emitting near-infrared light towards the head. In some embodiments, the first control element 22 can store illumination logic information for each light source 11, so that after the head-mounted near-infrared brain functional imaging device is started, each light source 11 can be directly illuminated according to the illumination logic information, simplifying operation. In some other embodiments, the first control element 22 can also receive control commands sent from outside, such as control commands sent from a host computer, and control the lighting mode of each light source 11 based on the control commands. In this way, the lighting mode of the light source 11 can be controlled more flexibly according to the needs.

[0033] In some embodiments, the first control element 22 can be implemented using a chip or discrete components, such as diodes and transistors. This application does not specifically limit its implementation; the control function can be achieved by constructing a circuit to control the switching of the light source 11 according to the control timing of its opening and closing. Preferably, the first control element 22 can be specifically a chip.

[0034] This application utilizes a light source control component 3 mounted on a headgear 1 and a main unit 2. The light source control component 3 includes multiple switches 31 electrically connected to light source elements 11 respectively. This allows the driver 21 located in the main unit 2 to be electrically connected to the multiple switches 31 respectively via a first cable 4. In other words, the switches 31 of the light source control component 3 and the driver 21 in the main unit 2 can be connected by a single cable, eliminating the need for separate cables for each driver 21 and light source element 11. This reduces the number of cables between the main unit 2 and the light source control component 3. The connection between the driver 21 and the switches 31 of the light source control component 3 can be achieved through the first cable 4, thereby controlling the corresponding light source element 11 through the switches 31. This effectively reduces the weight of the cables between the main unit 2 and the light source control component 3, thereby reducing excessive pressure on the head and improving the wearing comfort of the head.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, the light source control assembly 3 also includes a second control element 32. A second cable 5 is connected between the first control element 22 and the second control element 32. The first control element 22 is electrically connected to the switch element 31 through the second control element 32, so that the first control element 22 sends instructions to at least one switch element 31 through the second control element 32.

[0036] In this way, the electrical connection between the first control element 22 and the switch element 31 can be realized through the second control element 32. That is, the first control element 22 sends a command to the second control element 32, and the second control element 32 can control the switch element 31 to open or close based on the command. The second control element 32 can realize the transmission of precise control signals, ensuring that the second control element 32 can reliably send commands to the switch element 31, thereby accurately controlling the switch element 31 to open or close. Moreover, compared with the scheme where the first control element 22 is electrically connected to the switch element 31 through multiple cables, the first control element 22 can control each switch element 31 by only being electrically connected to the second control element 32 through the second cable 5, further reducing the problem of cable pressure on the head.

[0037] In some embodiments, the second control element 32 can be implemented using a chip or a discrete device, such as a diode and a transistor, to implement the control function. This application does not specifically limit the application in this regard. Preferably, the first control element 22 and the second control element 32 can be two different chips.

[0038] It is understood that the first control element 22 and the second control element 32 may also have other functions besides control functions. This application does not specifically limit them. For example, the first control element 22 may receive control commands sent by the host computer, or it may store the control timing of the opening and closing of the light source 11.

[0039] The second cable 5 can be set independently from the first cable 4, or it can be wrapped together with the first cable 4 as a whole. This application does not limit the specific form of the first cable 4 and the second cable 5, as long as they can transmit signals stably without interfering with each other.

[0040] Specifically, the first control element 22 can send a second control command to the second control element 32. Based on the second control command, the second control element 32 can send a command to one or more switches 31 to put one or more switches 31 into an open state.

[0041] In some other embodiments, the first control element 22 may be wirelessly connected to the second control element 32 to further reduce the required cable, thereby further reducing excessive pressure on the head from the cable.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the switch element 31 and the light source element 11 are arranged in a one-to-one correspondence.

[0043] In this way, the reliability of the control of the light source 11 can be increased by setting the switch 31 and the light source 11 in a one-to-one correspondence, so as to achieve precise control of the lighting or extinguishing of each light source 11 and reduce the possibility of confusion or erroneous operation in the control of the light source 11.

[0044] like Figure 2 As shown in the figure, there are n switching devices 31 and n light source devices 11, specifically switching devices 31a, ..., 31n (where n is the total number of switching devices 31), and light source devices 11a, ..., 11n (where n is the total number of light source devices 11). This allows switching devices 31a to control their corresponding light source devices 11a, ..., 31n to control their corresponding light source devices 11n, thus achieving precise control of each light source device 11. In the following text, without distinguishing between switching devices 31 and light source devices 11, the reference numeral 31 will be used to represent the switching device, and the reference numeral 11 will be used to represent the light source device.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, there are multiple drivers 21, and each driver 21, switch 31 and light source 11 is arranged in a corresponding manner. All drivers 21 are electrically connected to the corresponding switch 31 through the first cable 4.

[0046] In this way, by setting the driver 21, switch 31 and light source 11 one by one, the switch 31 can accurately control the light source 11, while the driver 21 can output stable power to the light source 11, ensuring that the corresponding light source 11 can reliably emit near-infrared light to the head.

[0047] like Figure 2 As shown in the figure, there are n drivers 21, specifically drivers 21a, ..., 21n (n is the total number of drivers 21). Driver 21a can stably output electrical energy to its corresponding light source 11a, so that the light source 11a is in a lightable state. After the switch 31a is turned on, the light source 11a can be lit. The control relationship between driver 21n, switch 31n and light source 11n can be deduced by analogy, which will not be elaborated here.

[0048] In some embodiments, such as Figure 1 and Figure 3 As shown, there are multiple light source control components 3, and the light source elements 11 are divided into multiple groups according to the different light source control components 3. The driver 21 is electrically connected to the switch element 31 of each light source control component 3. The first control element 22 is also used to simultaneously control the light source elements 11 of different groups to be in the lit state through the driver 21 and the switch element 31 of each light source control component 3.

[0049] Thus, the switching components 31 of multiple light source control components 3 can be controlled by the first control element 22 to make different groups of light source components 11 simultaneously lit, thereby improving the acquisition efficiency of near-infrared brain function data. Furthermore, the multiple light source control components 3 are electrically connected to the driver 21 included in a host 2, which can minimize the weight of the components mounted on the headgear 1 and further reduce the pressure on the head.

[0050] Specifically, the distance between different groups of light sources 11 that are simultaneously illuminated should be greater than a preset distance to avoid crosstalk caused by simultaneous emission of near-infrared light, which could affect the signal acquisition of the receiving probe and ensure the reliability and effectiveness of data acquisition. The different groups of light sources 11 that are simultaneously illuminated can be set according to parameters such as the acquisition area and acquisition frequency.

[0051] For example, such as Figure 1As shown in the figure, there are two light source control components 3 and two sets of light source elements 11. A first control command sent by the first control element 22 to the driver 21 can instruct at least one of the two sets of light source elements 11 to be in an illuminated state, that is, the driver 21 outputs electrical energy to at least one of the two sets of light source elements 11. A second control command sent by the first control element 22 to the switch 31 can instruct that at least one light source element 11 to be lit. The two sets of light source elements 11 correspond to opposite sides of the headgear 1 to maximize the spacing between the light source elements 11 that can be lit simultaneously in different sets of light source elements 11, ensuring that the distance between the simultaneously lit light source elements 11 is greater than a preset distance.

[0052] In some embodiments, the first control element 22 is used to control the driver 21 and the switch 31 to light up multiple light sources 11 in a time-sharing manner.

[0053] In this way, by sequentially illuminating the light source 11 and emitting near-infrared light to the head, it is ensured that the near-infrared light emitted by the illuminated light source 11 will not be affected by the near-infrared light emitted by other light source 11, thereby avoiding affecting the signal received by the receiving probe and ensuring the validity of the collected near-infrared brain function data.

[0054] For example, light sources 11a, ... 11n can be lit sequentially. Specifically, the first control element 22 controls light source 11a to be in an illuminateable state via driver 21a, and controls switch 31a to turn on light source 11a. Then, the first control element 22 can control driver 21a to stop supplying power to light source 11a, and control switch 31a to turn off. When light source 11b needs to be lit, the first control element 22 controls light source 11b to be in an illuminateable state via driver 21b, and controls switch 31b to turn on light source 11b. This process is repeated sequentially to achieve time-sharing lighting of light sources 11a, ... 11n.

[0055] In some embodiments, there are multiple drivers 21, and each driver 21 is electrically connected to at least one of the multiple switching elements 31 so as to simultaneously drive the light source element 11 electrically connected to the switching element 31 through the multiple drivers 21.

[0056] In this way, the light source 11, which is electrically connected to the at least one switch 31, can be controlled to emit light stably through multiple drivers 21 and at least one switch 31. This enables the light source 11 to be provided with sufficient power by multiple drivers 21, thus avoiding the problem that the light source 11 cannot work stably due to insufficient power.

[0057] In some embodiments, the plurality of drivers 21 may correspond to a switch 31, and the switch 31 may correspond to a light source 11. That is, the plurality of drivers 21 provide power to the light source 11 to ensure that the light source 11 can emit light stably.

[0058] In some embodiments, multiple switches 31 are electrically connected to at least one driver 21, so that the driver 21 controls the corresponding multiple light sources 11 to be in a lit state through the multiple switches 31.

[0059] In this way, by configuring multiple switches 31 and at least one driver 21, it is possible to output electrical energy to the light source 11 corresponding to each of the multiple switches 31 without setting up a separate driver 21 for each switch 31. This simplifies the setting of the driver 21, reduces manufacturing costs, and reduces the pressure exerted on the head by the host 2, further improving head comfort.

[0060] In some embodiments, the plurality of switches 31 may correspond to one driver 21, and the plurality of switches 31 may correspond to different light sources 11, so that the driver 21 can control the plurality of light sources 11 to be in an illuminated state. In this way, the number of drivers 21 in the host 2 can be reduced, thereby reducing the weight of the host 2 and further reducing the pressure on the head.

[0061] In some embodiments, such as Figure 1 As shown, the main unit 2 includes a first housing 23 detachably connected to the headgear 1, the driver 21 and the first control element 22 are both located in the first housing 23, the light source control component 3 includes a second housing 33 detachably connected to the headgear 1, and a plurality of switches 31 are located in the second housing 33. The first housing 23 and the second housing 33 are independently configured.

[0062] In this way, the independence of the main unit 2 and the light source control component 3 can be ensured by the independently set first housing 23 and second housing 33. The main unit 2 and the light source control component 3 can be detached from the headgear 1 for replacement and maintenance, which improves the ease of use of the head-mounted near-infrared brain function imaging device.

[0063] The first housing 23 can be connected to the head cap 1 by snap-fit ​​or adhesive methods. This application does not make specific limitations on this, as long as it can ensure that the first housing 23 is stably installed on the head cap 1.

[0064] The second housing 33 can be connected to the head cap 1 by snap-fit ​​or adhesive methods. This application does not make specific limitations on this, as long as it can ensure that the second housing 33 is stably installed on the head cap 1.

[0065] In some embodiments, when there are multiple light source control components 3, the multiple light source control components 3 may share a single second housing 33, or each light source control component 3 may have its own separate second housing 33. Preferably, each light source control component 3 has its own separate second housing 33, which not only enables the different light source control components 3 to be independent, but also improves the heat dissipation effect and prevents the temperature inside the second housing 33 from becoming too high when multiple light source control components 3 are working simultaneously.

[0066] In some embodiments, such as Figure 3 As shown, the head-mounted near-infrared brain functional imaging device also includes a power supply component 6, which is electrically connected to at least the first control element 22 in the host 2 to supply power to the first control element 22, and the power supply component 6 is not located on the headgear 1.

[0067] In this way, the pressure exerted on the head by the components on the headgear 1 can be further reduced by the power supply component 6 which is not located on the headgear 1, thereby improving head comfort.

[0068] like Figure 3 As shown, the aforementioned head-mounted near-infrared brain functional imaging device also includes a waist restraint structure. The power supply component 6 can be detachably connected to the waist restraint structure to ensure that the power supply component 6 can stably supply power to the first control element 22 while avoiding further pressure on the head.

[0069] In some other embodiments, the power supply component 6, which is electrically connected to the first control element 22, may be disposed on the headgear 1, so that the power supply component 6 can be disposed closer to the first control element 22, thereby shortening the length of the connecting cable between the two and making the head-mounted near-infrared brain function imaging device more compact.

[0070] This application also provides a head-mounted near-infrared brain functional imaging system 100. For example... Figure 4 As shown, the head-mounted near-infrared brain functional imaging system 100 includes the head-mounted near-infrared brain functional imaging device of any of the above embodiments, and also includes a host computer 7. The host computer 7 is communicatively connected to the first control element 22. The first control element 22 is used to receive the lighting command sent by the host computer 7 and control the multiple light sources 11 to be in the lighting state according to the lighting command.

[0071] Specifically, the host computer 7 can store lighting logic information for each light source 11. Based on this lighting logic information, the host computer 7 can send instructions to the first control element 22, enabling the first control element 22 to control each light source 11 to light up sequentially based on the lighting logic information. Of course, in some other embodiments, the host computer can also receive the input lighting logic information for each light source 11 and send instructions to the first control element 22 based on this lighting logic information. In this way, the lighting method of the light source 11 can be configured more flexibly according to needs.

[0072] The system using the aforementioned head-mounted near-infrared brain functional imaging device can precisely control the sequential lighting of each light source 11 based on the lighting command from the host computer 7. Furthermore, through the light source control component 3 located on the headgear 1 and the host 2, the driver 21 located in the host 2 can be electrically connected to multiple switches 31 via the first cable 4. That is, the switches 31 of the light source control component 3 and the driver 21 located in the host 2 can be connected by a single cable, eliminating the need to set up separate cables for each driver 21 and light source 11. This reduces the number of cables between the host 2 and the light source control component 3. In other words, the connection between the driver 21 and the switches 31 of the light source control component 3 can be achieved through the first cable 4, and the corresponding light source 11 can be controlled by the switches 31. This effectively reduces the weight of the cables between the host 2 and the light source control component 3, thereby reducing excessive pressure on the head and improving the wearing comfort of the head.
