Description

Technical Field

[0001] This application relates to the field of brain oxygenation monitoring technology, and more specifically, to a brain oxygenation monitoring probe and head-mounted device. Background Technology

[0002] Brain oxygenation monitoring equipment is used to monitor the oxygen saturation of brain tissue. The brain oxygenation monitoring probe primarily relies on Beer-Lambert's law and the significant difference in absorption of near-infrared light at specific wavelengths by deoxygenated and oxyhemoglobin. When near-infrared light shines through the skull, photons diffuse along multiple paths within the cranium. Some of the light is absorbed by different layers of tissue, such as the skull, scalp, and brain, while the remaining photons are scattered along the so-called "banana" model within the brain tissue.

[0003] In brain oxygenation monitoring probes, LED light sources typically emit three near-infrared wavelengths (such as 735 nm, 810 nm, and 850 nm). After these wavelengths of light penetrate the skull and brain tissue, the proximal and distal sensors receive the signals in different ways to distinguish the blood oxygenation information of superficial and deep tissues (especially brain tissue).

[0004] When wearing a brain oxygenation monitoring probe, the probe needs to contact the scalp to reduce hair obstruction in order to meet the accuracy of monitoring. However, the human head is curved, while the side of the probe that contacts the scalp is flat, which makes it difficult for the probe to make good contact with the scalp. In addition, gaps can easily form between the receiver and transmitter on the probe and the scalp, resulting in errors and inaccurate monitoring data. Summary of the Invention

The probe also includes a floating component, which is located on the side of the first housing facing the subject and rotatably connected to the first housing. One of the transmitter and receiver is located in the first housing, and the other is located in the floating component. Because the monitored person's head has a curvature, when the brain oxygenation monitoring probe contacts the monitored person's scalp, the monitored person's head can cause the floating component to rotate relative to the first housing.

Detailed Implementation

[0036] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0037] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] like Figure 1As shown, in a first aspect, embodiments of this application provide a brain oxygenation monitoring probe, including a first housing 1, which can be used to house components such as circuit boards; the brain oxygenation monitoring probe also includes a monitoring channel assembly, which is used to monitor the brain oxygenation of a monitored subject, the monitoring channel assembly includes at least one transmitter 2 and at least one receiver 3, the transmitter 2 is used to emit near-infrared light toward the head of the monitored subject, and the receiver 3 is used to receive near-infrared light, the transmitter 2 and the receiver 3 cooperate with each other to monitor the brain oxygenation of the monitored subject; the brain oxygenation monitoring probe also includes a floating member 4, which is disposed on the side of the first housing 1 facing the monitored subject and is rotatably connected to the first housing 1, one of the transmitter 2 and the receiver 3 is disposed on the first housing 1. The other component is located on the floating element 4. Since the head of the monitored person has a curvature, when the brain oxygenation monitoring probe contacts the scalp of the monitored person, the head of the monitored person can cause the floating element 4 to rotate relative to the first housing 1. Adjusting the angle between the floating element 4 and the first housing 1 is also adjusting the tilt angle of the floating element 4 relative to the first housing 1. In this way, the tilt angle between the floating element 4 and the first housing 1 can be adapted to the curvature of the monitored person's head. The transmitter 2 or receiver 3 on the floating element 4 and the receiver 3 or transmitter 2 on the first housing 1 can make better contact with the scalp of the monitored person, reducing the gap between the transmitter 2 or receiver 3 on the floating element 4 and the scalp, thereby improving the accuracy of the data monitored by the monitoring channel component.

[0039] Optionally, in some cases, the transmitter 2 and receiver 3 can also be installed on the floating component 4.

[0040] Optionally, the floating member 4 can rotate toward the center of the first housing 1, thereby adjusting the angle between the floating member 4 and the first housing 1.

[0041] Optionally, the angle between the floating component 4 and the first housing 1 can be an obtuse angle. With this setting, when the receiving end 3 or the transmitting end 2 on the floating component 4 comes into contact with the scalp, a very small force can be used to make both the transmitting end 2 and the receiving end 3 fit against the scalp.

[0042] Optionally, the transmitter 2 can be two LED light sources capable of emitting near-infrared light. Of course, in some cases, a higher-power laser can also be used instead. The receiver 3 can be a photoelectric sensor, such as an avalanche photodiode, used to receive near-infrared light signals scattered back from brain tissue. The receiver 3 can include a near-end receiving sensor or a near-end receiving sensor and a far-end receiving sensor.

[0043] Optionally, in this embodiment of the application, the brain oxygenation monitoring probe may only have a first housing 1, and the first housing 1 contains components such as a circuit board; in some cases, the brain oxygenation monitoring probe may also include a first housing 1 and a second housing 8, and the first housing 1 and the second housing 8 are independent components, that is, the brain oxygenation monitoring probe is a split structure.

[0044] Optionally, the tilt angle between the floating component 4 and the first housing 1 means that when the first housing 1 is placed horizontally, the floating component 4 is tilted relative to the first housing 1.

[0045] In one embodiment, the cerebral oxygenation monitoring probe also includes an elastic element, which is disposed between the floating element 4 and the first housing 1. The elastic element is used to adjust the tilt angle of the floating element 4. When the receiving end 3 or the transmitting end 2 on the floating element 4 comes into contact with the scalp, the contact force generated between the floating element and the scalp can compress the elastic element, causing the floating element 4 to rotate relative to the first housing 1, thereby adjusting the angle between the floating element 4 and the first housing 1, that is, adjusting the tilt angle of the floating element 4 relative to the first housing 1, so that the transmitting end 2 or the receiving end 3 on the floating element 4 fits the scalp better.

[0046] Optionally, the elastic element can be a torsion spring, which can be set at the hinge position between the floating element 4 and the first housing 1; of course, the elastic element can also be a columnar spring, which is set between the floating element 4 and the first housing 1, and can compress the spring when the floating element 4 is subjected to the abutment force of the scalp.

[0047] like Figure 3 As shown, in one embodiment, the first housing 1 includes a body portion 11 and a protrusion 12. The protrusion 12 is disposed on the side of the body portion 11 facing the monitored person. The receiving end 3 is disposed on the protrusion 12. The protrusion 12 protrudes from the body portion 11, making it easier for the receiving end 3 to fit against the scalp of the monitored person. The body portion 11 is disposed below the protrusion 12, which also provides space for the floating member 4 to be disposed circumferentially on the protrusion 12. The transmitting end 2 is disposed on the floating member 4. The floating member 4 is located on the side of the body portion 11 facing the monitored person. The floating member 4 is hinged to the protrusion 12. The floating member 4 can rotate toward the protrusion 12, so that the floating member 4 and the protrusion 12 form an inclined angle. When the transmitting end 2 contacts the scalp, the contact force generated between the scalp and the scalp will cause the floating member 4 to move toward the body portion 11, thereby increasing the angle between the floating member 4 and the protrusion 12. This allows the receiving end 3 and the transmitting end 2 to better adapt to the curvature of the head, improving the accuracy of the monitoring data.

[0048] Optionally, the elastic element can be disposed between the floating element 4 and the main body 11.

[0049] like Figure 1As shown, in one embodiment, there are multiple floating elements 4, which are arranged around the protrusion 12. In this way, the receiving end 3 on the protrusion 12 can be reused by the transmitting end 2 on the multiple floating elements 4. That is, the receiving end 3 on the protrusion 12 can be shared by multiple transmitting ends 2. By using time-division multiplexing, the receiving end 3 can receive three different near-infrared wavelengths in sequence. At the same time, there is no need to set up more additional receiving ends 3, thereby reducing the size of the probe.

[0050] Optionally, three floating elements 4 are provided, and the three floating elements 4 are evenly arranged along the outer periphery of the protrusion 12 so that the distance from the transmitting end 2 on the floating element 4 to the receiving end 3 on the protrusion 12 is equal.

[0051] Optionally, in this embodiment, a receiver 3 is provided on the protrusion 12 instead of a transmitter 2. The transmitter 2 is provided on the floating member 4. The receiver 3 can be shared and reused by multiple transmitters 2, which reduces the probe size and increases the data processing speed. In some cases, a transmitter 2 can also be provided on the protrusion 12 and a receiver 3 can be provided on the floating member 4. However, this arrangement will cause multiple receivers 3 on multiple floating members 4 to share the receivers on the transmitters 2 on the protrusion 12, increasing power consumption. At the same time, it will also cause electrical noise to be superimposed. In addition, each sensor of the receiver 3 needs to be independently gain-calibrated at the factory, increasing the cost.

[0052] like Figure 5 As shown, in one embodiment, the floating member 4 includes a connecting part 41 and a main body part 42 connected to the connecting part 41. The connecting part 41 protrudes along one side of the main body part 42, and the main body part 42 is located on the outer periphery of the protrusion 12, providing installation space for the floating member 4. This allows the height between the receiving end 3 and the transmitting end 2 to be close to the same plane, reducing the height difference between the receiving end 3 and the transmitting end 2. The protrusion 12 is provided with a slot 121, and the connecting part 41 is inserted into the slot 121 and hinged to the protrusion 12, making the structure between the floating member 4 and the first housing 1 more compact, reducing the size of the probe, reducing the wearing burden, and making it easier for the brain blood oxygen monitoring probe to fit the scalp. Furthermore, the hinge between the connecting part 41 and the protrusion 12 can reduce the interference between the main body part 42 and the protrusion 12, and can form an angle between the main body part 42 and the protrusion 12. When the main body part 42 is subjected to a resisting force, it can move towards the main body part 11, making it easier to adapt to the curvature of the head.

[0053] Optionally, the side of the main body 42 facing the protrusion 12 is designed with an arc shape and is adapted to the outer side of the protrusion 12, so that the main body 42 and the protrusion 12 are more compact.

[0054] Optionally, the connecting part 41 and the protrusion 12 can be hinged by a connecting shaft, and the torsion spring can be mounted on the connecting shaft.

[0055] like Figure 3 and 5 As shown, in one embodiment, the first housing 1 further includes a limiting part 13, which is connected to the protrusion 12 and / or the body part 11. The limiting part 13 and the body part 11 are spaced apart to form a first gap. A portion of the floating member 4 extends into the first gap. The limiting part 13 and the body part 11 are used to cooperate to limit the rotation range of the floating member 4, so as to avoid the angle between the floating member 4 and the body part 42 being too large, that is, the angle of the floating member 4 being too large. When wearing it, more force is needed to abut the floating member 4 so that the receiving end 3 on the protrusion 12 can contact the scalp. That would easily cause a gap to be generated between the receiving end 3 or the transmitting end 2 and the scalp. The limiting part 13 can limit the angle of the floating member 4 being raised.

[0056] Optionally, the floating member 4 includes bosses located on both sides, with the two bosses respectively located in the first gap.

[0057] Optionally, the limiting part 13 extends outward along the circumference of the protrusion 12, with one end connected to the protrusion 12 and the other end connected to the main body part 42 via a connecting segment; it may also be connected to the protrusion 12 but not to the main body part 42; or it may be connected to the main body part 42 via a connecting segment but not to the protrusion 12.

[0058] like Figure 3 As shown, in one embodiment, the floating part 4 is also provided with a first protective part 5. The first protective part 5 faces the side of the monitored person. The first protective part 5 is provided with a receiving cavity, which contains a part of the transmitter 2. By setting the first protective part 5, the transmitter 2 can be protected, and the cerebral blood oxygen monitoring probe can be prevented from falling to the ground and causing the transmitter 2 to break.

[0059] Optionally, the first protective part 5 can be a silicone part or a plastic part.

[0060] Optionally, each transmitter 2 includes at least two LED light sources, each LED light source including a light guide column and a convex lens, the convex lens protruding from the first protective part 5 for easy contact with the scalp.

[0061] like Figure 1As shown, in one embodiment, the cavity wall of the receiving cavity is also provided with a first notch 51. The first notch 51 extends from the end away from the floating member 4 toward the floating member 4, that is, the first notch 51 extends from the end away from the connection between the first protective part 5 and the main body part 42 toward the end where the first protective part 5 and the main body part 42 are connected. The transmitting end 2 includes two emitting light sources located in the receiving cavity. A second gap is formed between the two emitting light sources. The second gap is arranged opposite to the first notch 51 and is connected to the first notch 51, so that the hair of the person being monitored can enter the second gap through the first notch 51, avoiding the hair from blocking the emitting light source.

[0062] Optionally, the hair can be pushed aside by the convex lens at the end of the transmitter 2 by rotating the brain oxygenation monitoring probe, so that the hair can enter the second gap; in addition, the first protective part 5 is a columnar structure, and when the brain oxygenation probe is rotated, the first protective part 5 can also play the role of pushing aside the hair, that is, the outer periphery of the first protective part 5 can push aside the hair.

[0063] Optionally, the first protective part 5 is wrapped around the periphery of the two emitting light sources, and the first notch 51 is provided in two ways so that the hair can enter the second gap from different directions.

[0064] like Figure 4 As shown, in one embodiment, the main body 42 is provided with a mounting groove for accommodating the first circuit board 44. The first circuit board 44 is connected to the transmitter 2, thereby enabling the transmitter 2 to send signals. The floating member 4 also includes a blocking part 43, which is connected to the first circuit board 44 and is used to block the mounting groove to improve the stability of the first circuit board 44. The blocking part 43 is provided with a hole for the ribbon cable to pass through, so that the signal and current provided to the transmitter 2 and the signal generated by the transmitter 2 can be transmitted through the ribbon cable. The ribbon cable is small in size and can pass through the hole of the blocking part 43.

[0065] Optionally, the hole in the sealing part 43 can be a hole opened in the sealing part 43 itself, or it can be a gap formed between the sealing part 43 and the main body part 42.

[0066] Optionally, the blocking part 43 is located at the opposite end of the transmitter 2, and the cable can be passed out from the bottom of the transmitter 2. This does not affect the operation of the transmitter 2, and the cable can also be shielded through the connecting part 41 to improve aesthetics.

[0067] Optionally, each floating element 4 may contain a first circuit board 44.

[0068] Optionally, the sealing part 43 and the main body part 42 can be connected by fasteners.

[0069] like Figure 2As shown, in one embodiment, the protrusion 12 is provided with a plurality of receiving ends 3, which are respectively configured as a plurality of first receiving ends and second receiving ends. The plurality of first receiving ends are evenly arranged along the circumference of the second receiving ends, and the second receiving ends are shared by a plurality of transmitting ends 2 in the same monitoring channel (e.g., Figure 2 As shown by the arrow in the diagram, the second receiving end is located between the first receiving end and the transmitting end 2, and there is a transmitting end 2 on the extension line connecting the first receiving end and the second receiving end. In this way, in one monitoring channel, the near-infrared light emitted by one transmitting end 2 can be received by the first receiving end and the second receiving end respectively after passing through the head. Then, after analysis and processing by the corresponding algorithm, the brain blood oxygen saturation of the monitored person can be calculated. Moreover, the second receiving end can be shared by three monitoring channels, thereby reducing the size of the brain blood oxygen monitoring probe and the production cost.

[0070] Optionally, three first receivers are provided, each corresponding to a transmitter 2 on one of the three floating components 4, thus forming three monitoring channels.

[0071] like Figure 2 As shown, optionally, a second receiving end can be set as the proximal sensor for each monitoring channel. This is because the proximal sensor mainly receives scattered light from superficial tissues (such as the scalp and skull) and is used to filter out superficial interference signals. It serves as a background noise reference in the algorithm and is not directly used to calculate cerebral blood oxygenation. The first receiving end serves as the distal sensor for each monitoring channel. Each first receiving end includes two distal sensors because the distal sensors receive signals from deeper tissues, including the cerebral cortex region, and are the main basis for calculating cerebral blood oxygen saturation. By modifying the Lambert-Beer law to analyze light attenuation at different wavelengths, the ratio of oxygenated to deoxygenated hemoglobin concentration is estimated. Setting two distal sensors for each monitoring channel improves the accuracy of the monitoring data. At the same time, when one of the distal sensors is blocked by hair, the other can continue to work.

[0072] like Figure 2 As shown, optionally, in the same monitoring channel, the transmitter 2, the first receiver and the second receiver are on the same straight line.

[0073] Optionally, the first receiver can be a silicon photodiode, and the second receiver can be an avalanche photodiode.

[0074] like Figure 3As shown, in one embodiment, the protrusion 12 is also provided with a plurality of second protective parts 6 and third protective parts. The second protective parts 6 and the third protective parts both protrude from the protrusion 12. The second protective part 6 is provided with a cavity for accommodating a portion of the first receiving end; the third protective part is provided with a cavity for accommodating a portion of the second receiving end. By providing the second protective parts 6 and the third protective parts, the first receiving end and the second receiving end can be protected respectively, and the first receiving end and the second receiving end can be prevented from breaking.

[0075] Optionally, the second protective part 6 and the third protective part can be silicone or plastic. In addition, the second protective part 6 and the third protective part are columnar structures. When rotating the brain oxygenation probe, the second protective part 6 and the third protective part can play the role of parting the hair, that is, the outer periphery of the second protective part 6 and the third protective part can part the hair.

[0076] like Figure 1 As shown, in one embodiment, the second protective part 6 is provided with a second notch 61 on its periphery. The first receiving end includes two receiving sensors, and a third gap is formed between the two receiving sensors. The second notch 61 is disposed opposite to the third gap, and the third gap is connected to the second notch 61, so that the hair of the person being monitored can enter the third gap through the second notch 61, thus avoiding the hair from blocking the receiving sensors.

[0077] Optionally, the second notch 61 extends from one end away from the protrusion 12 toward the end where the second protective part 6 is connected to the protrusion 12.

[0078] Optionally, the end of the receiving sensor is also equipped with a convex lens, which can be used to push the hair aside by rotating the cerebral oxygenation monitoring probe, allowing the hair to enter the third gap.

[0079] Optionally, the second protective part 6 is arranged circumferentially along the two receiving sensors, and two second notches 61 are provided.

[0080] like Figure 3 As shown, in one embodiment, a spacer 7 is provided between the first receiver and the transmitter 2. The spacer 7 is detachably connected to the protrusion 12, thereby facilitating the replacement of the spacer 7. The spacer 7 is provided between the first receiver and the transmitter 2. The spacer 7 can separate the receiver 3 and the transmitter 2. For some subjects who have no hair or sparse hair, the spacer 7 can replace the function of hair, separating the transmitter 2 and the receiver 3, so that the near-infrared light emitted by the transmitter 2 can pass through the head first and then be received by the receiver 3, avoiding the near-infrared light emitted by the transmitter 2 being directly received by the first receiver or the second receiver without passing through the head.

[0081] Optionally, the spacer 7 includes a sidewall surrounding the periphery of a plurality of first receiving ends. The spacer 7 also includes a base plate connected to the sidewall. The base plate can be detachably connected to the protrusion 12, either by adhesive or by snap-fit.

[0082] As one implementation method, the spacer 7 is a flexible component. Since the spacer 7 is in contact with the scalp, the flexibility of the spacer 7 can improve the wearing comfort. At the same time, it can deform when in contact with the scalp to adapt to the curvature of the scalp.

[0083] Optionally, the spacer 7 can be a silicone part or a rubber part, etc.

[0084] like Figure 5 , 6 As shown in Figure 11, in one embodiment, the first housing 1 is further provided with a second circuit board 14. The second circuit board 14 is connected to multiple receivers 3. The second circuit board 14 is connected to the first circuit board 44 via a ribbon cable, realizing the electrical connection between the first circuit board 44 and the second circuit board 14, as well as the synergistic effect of the receivers 3 and the transmitters 2. The cerebral oxygenation monitoring probe also includes a support member 16. The second circuit board 14 is located between the support member 16 and the protrusion 12. The support member 16, the second circuit board 14, and the protrusion 12 are connected by fasteners. The support member 16 provides support and fixation for the second circuit board 14 and prevents the second circuit board 14 from shaking in the first housing 1. At the same time, it also separates the second circuit board 14 from the third circuit board 15.

[0085] Optionally, the first receiving end and the second receiving end can be connected to the first side of the second circuit board 14 via a ribbon cable to improve assembly efficiency. The first side can be the side facing the receiving end 3. The ribbon cable connected to the first circuit board 44 can be connected to the second side of the second circuit board 14, which is the opposite side of the first side.

[0086] like Figure 3 As shown, optionally, the main body 11 is provided with a plurality of through holes 111 through which ribbon cables can pass. The through holes 111 are used to guide the ribbon cable connected to the first circuit board 44. One end of the ribbon cable is connected to the first circuit board 44, and the other end passes through the hole provided in the sealing part 43 and then through the through hole 111 to be electrically connected to the second circuit board 14 inside the first housing 1, so that the transmitting end 2 and the receiving end 3 can simultaneously receive signals and power.

[0087] like Figure 5 and 6As shown, in one embodiment, the cerebral oxygenation monitoring probe also includes a first fastening member 17, which is detachably connected to the first housing 1, thereby facilitating the installation and maintenance of parts inside the first housing 1. A third circuit board 15 is also provided between the first fastening member 17 and the first housing 1, and the third circuit board 15 is electrically connected to the second circuit board 14, thereby enabling control of the receiver 3 and the transmitter 2. The third circuit board 15 provides a switching function, and the second circuit board 14 and the third circuit board 15 can perform different functions. The cerebral oxygenation monitoring probe also includes a second housing 8, which contains a fourth circuit board 81. The second housing 8 is detachably connected to the first housing 1. Furthermore, when a component inside the first housing 1 or the second housing 8 is damaged, the component inside the first housing 1 and the component inside the second housing 8 can be repaired separately, improving the convenience of maintenance. When a component inside the first housing 1 or the second housing 8 is damaged, a single part can also be replaced, reducing costs. In contrast, the cerebral oxygenation monitoring probe is a single integrated housing. If a component is damaged, the entire housing needs to be disassembled for repair, which is more cumbersome. Moreover, when the cerebral oxygenation monitoring probe needs to be replaced, the entire probe can only be replaced, which is more costly. When the second housing 8 is connected to the first housing 1, the fourth circuit board 81 is electrically connected to the third circuit board 15, thereby realizing the circuit connection and control between the receiver 3 and the transmitter 2.

[0088] Optionally, the first fastener 17 and the first housing 1 can be connected by a snap-fit, the first fastener 17 supports the third circuit board 15, and the first fastener 17, the third circuit board 15 and the first housing 1 can be connected by fasteners.

[0089] Optionally, the fourth circuit board 81 can be connected to a power cord.

[0090] Optionally, an additional circuit board can be installed inside the second housing 8.

[0091] Optionally, the third circuit board 15 can be connected to the second circuit board 14 via a ribbon cable.

[0092] Optionally, the fourth circuit board 81 can implement driving functions, such as providing a constant current source, high voltage or high current transient supply, and safety protection; the third circuit board 15 can implement control functions, such as closed-loop light intensity adjustment, timing arrangement and multiplexing, and fault decision-making.

[0093] Optionally, when it is impossible to determine whether the first housing 1 or the second housing 8 is damaged, the first housing 1 can be connected to another second housing 8, or the second housing 8 can be connected to another first housing 1, so as to detect which housing has damaged parts, thereby improving detection efficiency.

[0094] like Figures 5 to 7As shown, in one embodiment, the third circuit board 15 is provided with a first conductive part 151, and the fourth circuit board 81 is provided with a second conductive part 811; the first fastening member 17 is provided with a first exposed area 171, which is used to expose the first conductive part 151; the cerebral blood oxygen monitoring probe also includes a second fastening member 9, which is detachably connected to the second housing 8 to form a cavity for accommodating parts, facilitating the installation and maintenance of parts inside the second housing 8; the second fastening member 9 is provided with a second exposed area 91, which is used to expose the second conductive part 811. Thus, when the first housing 1 and the second housing 8 need to be connected, the first fastening member 17 and the second fastening member 9 are arranged opposite to each other, and the first conductive part 151 and the second conductive part 811 can be electrically connected through the first exposed area 171 and the second exposed area 91 respectively, thereby realizing the power supply and control of the receiver 3 and the transmitter 2.

[0095] Optionally, the first conductive part 151 can be an elastic probe, and the second conductive part 811 can be a contact point. When the elastic probe contacts the contact point, the circuit between the third circuit board 15 and the fourth circuit board 81 is connected. Of course, the first conductive part 151 can also be a contact point, and the second conductive part 811 can also be an elastic probe.

[0096] Optionally, four first exposed areas 171 can be set, and four corresponding second exposed areas 91 can be set.

[0097] like Figure 6 As shown, in one embodiment, the first fastening member 17 is further provided with a snap-fit ​​portion 10. The snap-fit ​​portion 10 is located at the edge of the first exposed area 171 and can be inserted into the second exposed area 91. On the one hand, the snap-fit ​​portion 10 can be inserted into the second exposed area 91 to improve the stability between the first housing 1 and the second housing 8. On the other hand, by providing the snap-fit ​​portion 10, when the first housing 1 and the second housing 8 need to be connected, the purpose of quick assembly can be achieved. Alternatively, in another embodiment, the second fastening member 9 is provided with a snap-fit ​​portion 10. The snap-fit ​​portion 10 is located at the edge of the second exposed area 91 and can be inserted into the first exposed area 171.

[0098] Optionally, the snap-fit ​​portion 10 protrudes from the first fastening member 17 and is positioned toward the second fastening member 9; if the second fastening member 9 is provided with the snap-fit ​​portion 10, the snap-fit ​​portion 10 may also protrude from the second fastening member 9 and be positioned toward the first fastening member 17.

[0099] Optionally, in this embodiment, since four first exposed areas 171 are provided, four snap-fit ​​parts 10 are also provided. To achieve rapid assembly and docking between the first housing 1 and the second housing 8, the first exposed areas 171 can be designed with different areas, and correspondingly, the snap-fit ​​parts 10 are also of different sizes. The corresponding second exposed areas 91 correspond to the sizes of the corresponding snap-fit ​​parts 10. Thus, when the first housing 1 and the second housing 8 are connected, the snap-fit ​​parts 10 of the same size correspond to the second exposed areas 91, achieving rapid insertion and connection. When the second fastening member 9 is provided with snap-fit ​​parts 10, the principle is the same as described above, and will not be repeated here.

[0100] like Figure 1 As shown, in one embodiment, the cerebral oxygenation monitoring probe also includes a locking member 20, which is connected to the second housing 8. The locking member 20 is used to lock or unlock the first housing 1 and the second housing 8, so that the first housing 1 and the second housing 8 cannot be separated after being connected, and can only be separated by unlocking the locking member 20 when separation is required.

[0101] like Figure 6 , 8 As shown in Figure 11, in one embodiment, the outer periphery of the first fastening member 17 is further provided with a first locking block 172, and the locking member 20 includes a second locking block 201. When the first fastening member 17 and the second fastening member 9 are in contact, the locking member 20 can rotate relative to the second housing 8. In the direction perpendicular to the plane formed by the second fastening member 9, that is, perpendicular to the direction of the second fastening member 9, the second locking block 201 and the first locking block 172 are at different heights. The first locking block 172 and the second locking block 201 are at different heights, and during the rotation of the locking member 20, the vertical projection of the second locking block 201 can at least partially coincide with the first locking block 172, thereby realizing the mutual locking of the first housing 1 and the second housing 8.

[0102] Optionally, when unlocking is required, the locking member 20 can rotate in the opposite direction so that the first locking block 172 and the second locking block 201 do not coincide on the projection perpendicular to the direction of the second fastening member 9.

[0103] Optionally, the second locking block 201 and the first locking block 172 being in different positions means that when the first housing 1 and the second housing 8 are connected, the first locking block 172 and the second locking block 201 are at different heights in the direction perpendicular to the second fastening member 9. When locked, their projections can partially or completely overlap, and when unlocked, their vertical projections do not overlap.

[0104] Optionally, the first locking block 172 and the first fastening member 17 are integrally formed to meet the structural strength requirements.

[0105] Optionally, the direction perpendicular to the plane formed by the second fastening member 9 refers to the direction perpendicular to the second fastening member 9. Since there are multiple directions perpendicular to the second fastening member 9, in this embodiment, it refers to the direction perpendicular to the plane formed by the second fastening member 9. It can also be understood as the direction perpendicular to the second housing 8 when the bottom of the second housing 8 is placed horizontally.

[0106] In one embodiment, the locking member 20 has an unlocked position and a locked position. The locking member 20 can rotate freely relative to the second housing 8 in the unlocked and locked positions, thereby achieving the purpose of locking or unlocking the first housing 1 and the second housing 8. When the locking member 20 is in the unlocked position, the latching part 10 can be inserted into the first exposed area 171 or the second exposed area 91, thereby facilitating the quick locking of the first housing 1 and the second housing 8 and avoiding the need for the first housing 1 and the second housing 8 to be aligned and find the locking position during the locking process.

[0107] Optionally, when the first housing 1 and the second housing 8 need to be connected, if the snap-fit ​​part 10 is not inserted into the first exposed area 171 or the second exposed area 91, since the snap-fit ​​part 10 is protruding, the snap-fit ​​part 10 is in contact with the first fastening member 17 or the second fastening member 9. The first locking block 172 and the second locking block 201 are at the same height in the direction perpendicular to the plane formed by the second fastening member 9, and the locking member 20 cannot rotate. That is, the first locking block 172 and the second locking block 201 will limit each other and cannot lock. Therefore, inserting the snap-fit ​​part 10 into the first exposed area 171 or the second exposed area 91 is to achieve the initial positioning of locking, and also to initially limit the first housing 1 and the second housing 8, and also to achieve the purpose of electrically connecting the multiple first conductive parts 151 and the multiple second conductive parts 811 respectively.

[0108] like Figure 9 As shown, in one embodiment, multiple second locking blocks 201 are provided, and the multiple second locking blocks 201 are arranged at intervals along the circumference of the locking member 20. The first locking block 172 can pass through two adjacent second locking blocks 201. When the locking member 20 is in the unlocked position, the snap-fit ​​part 10 can be inserted into the first exposed area 171 or the second exposed area 91 at the same time, so as to achieve the initial accurate positioning of the first housing 1 and the second housing 8 and improve the connection efficiency.

[0109] Optionally, multiple first locking blocks 172 are also provided to improve the stability of the first housing 1 and the second housing 8 after locking.

[0110] like Figure 8 and 9As shown, in one embodiment, the locking member 20 includes a locking ring that extends axially to form a peripheral wall. The inner peripheral wall of the locking ring is provided with a first protrusion 202. The first protrusion 202 extends circumferentially along the locking ring and the two ends of the extension are spaced apart to form an active area 204. The second fastening member 9 includes a stop block 92 located in the active area 204. The stop block 92 abuts against one end of the first protrusion 202 to form the unlocked position of the locking member 20, and abuts against the other end to form the locked position of the locking member 20. Through the mutual cooperation between the second fastening member 9 and the locking member 20, on the one hand, the rotation angle of the locking member 20 can be limited, and on the other hand, the purpose of unlocking or locking the locking member 20 can be achieved.

[0111] Optionally, the first protrusion 202 extends radially inward along the locking ring.

[0112] like Figure 9 and 11 As shown, optionally, the inner peripheral wall of the locking ring is also provided with a second protrusion 203. The second protrusion 203 extends circumferentially along the locking ring to form a closed structure. The second protrusion 203 is located radially inward along the inner peripheral wall and the length of the extension is greater than that of the first protrusion 202. The second protrusion 203 is located below the first protrusion 202. When the second fastening member 9 is connected to the second housing 8, the second fastening member 9 forms an axial limit on the second protrusion 203, so that the locking member 20 can rotate independently relative to the second housing 8. At the same time, the stop block 92 is also located in the active area 204.

[0113] Optionally, the outer surface of the locking ring may also be textured to increase friction.

[0114] like Figure 8 As shown, optionally, when the locking member 20 is in the unlocked position, the stop block 92 abuts against one end of the first protrusion 202, the first locking block 172 passes through two adjacent second locking blocks 201, and the multiple snap-fit ​​parts 10 can also be inserted into different second exposed areas 91 respectively. The first housing 1 and the second housing 8 are initially positioned, and the first locking block 172 and the second locking block 201 are located at different heights perpendicular to the direction of the second fastening member 9. When the locking member 20 is rotated, the first locking block 172 and the second locking block 201 coincide in the plane direction perpendicular to the plane formed by the second fastening member 9, thereby locking the first housing 1 and the second housing 8. When the locking member 20 is rotated further, the stop block 92 abuts against the other end of the first protrusion 202 in the active area 204, and the first locking block 172 and the second locking block 201 completely coincide in the plane direction perpendicular to the plane formed by the second fastening member 9.

[0115] Optionally, if the locking member 20 is not in the unlocked position, the first locking block 172 can be located between two adjacent second locking blocks 201, but it cannot pass through the two adjacent second locking blocks 201. This is because the first fastening member 17 and the first housing 1 also need to be rotated by a certain angle so that the first locking block 172 is inserted between two adjacent second locking blocks 201. This will cause the latching part 10 on the first fastening member 17 to be unable to be inserted into the second exposed area 91. In other words, in the unlocked position, the first locking block 172 passing through two adjacent second locking blocks 201 and the multiple latching parts 10 being able to be inserted into the corresponding second exposed area 91 are uniquely corresponding.

[0116] Optionally, the distance between the second locking block 201 and the first protrusion 202 does not exceed the thickness of the first locking block 172. This is because when the first housing 1 and the second housing 8 are connected, the first locking block 172 is located between the second locking block 201 and the first protrusion 202. During the rotation of the locking member 20, the second locking block 201 and the first protrusion 202 can exert a squeezing effect on the first locking block 172 to achieve the purpose of locking.

[0117] Optionally, the locking element 20 can be configured to be unlocked when rotated clockwise and locked when rotated counterclockwise.

[0118] In one embodiment, the first locking block 172 has a first guide slope on the side opposite to the second locking block 201, and the second locking block 201 has a second guide slope on the side opposite to the first locking block 172. By respectively setting the first guide slope and the second guide slope, when ready to lock, the first guide slope and the second guide slope can cooperate with each other, so that the first locking block 172 and the second locking block 201 coincide in the direction perpendicular to the second fastening member 9, and the locking member 20 continues to rotate, and the second locking block 201 and the first protrusion 202 squeeze the first locking block 172.

[0119] like Figure 6 and 8As shown, in one embodiment, a first protrusion 173 is provided on the side of the first locking block 172, the first protrusion 173 is spaced apart from the first locking block 172 and located at one end of the first guide slope; a second protrusion 205 is provided between the second locking block 201 and the first protrusion 202, the second protrusion 205 is located at the end of the second locking block 201 away from the second guide slope; when the locking member 20 is in the locked position, the second protrusion 205 is located between the first protrusion 173 and the first locking block 172, thereby restricting the locking member 20 and preventing the locking member 20 from being accidentally activated. Unlocking; at the same time, since the second locking block 201 and the first protrusion 202 squeeze the first locking block 172, the second protrusion 205 located between the first protrusion 173 and the first locking block 172 also serves as a double locking purpose, further restricting the first housing 1 and the second housing 8 after locking. At the same time, when the second protrusion 205 is located between the first protrusion 173 and the first locking block 172, it will provide the installer or medical staff with a "stepping sensation", letting the installer or medical staff know that the first housing 1 and the second housing 8 have been locked in place.

[0120] Optionally, the first protrusion 173 and the first locking block 172 are located on the same circumferential direction, and the second protrusion 205 is located between the second locking block 201 and the first protrusion 202 in the axial direction of the second housing 8, meaning that the second protrusion 205 is located between the second locking block 201 and the first protrusion 202.

[0121] Optionally, the distance between two adjacent second locking blocks 201 needs to satisfy the simultaneous passage of the first locking block 172 and the first protrusion 173.

[0122] Secondly, embodiments of this application also provide a head-mounted device that can be worn on the head of the person being monitored to monitor the cerebral blood oxygenation of the person being monitored.

[0123] Optionally, the head-mounted device includes a headgear with multiple cerebral oxygenation monitoring probes provided in the first aspect.

[0124] Optionally, the outer surface of the second housing 8 is also provided with a clamping groove, which can clamp the headgear, thereby realizing the connection between the headgear and the cerebral blood oxygen monitoring probe.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.

[0126] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0127] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
