Description

Technical Field

[0001] The present application relates to the technical field of near-infrared brain function imaging, and in particular to a probe fixing device for near-infrared brain function imaging equipment. Background Art

[0002] With the in-depth development of medical and neuroscience fields, near-infrared technology has been widely used in non-invasive monitoring and diagnosis. As the core component of this technology, the near-infrared probe should be firmly installed on the near-infrared head cap during use to ensure the accuracy and effectiveness of the near-infrared data.

[0003] At present, the near-infrared probe holder mainly fixes the probe in the accommodation cavity formed by the upper cover and the buckle by making the upper cover deform under force so that it can be buckled onto the buckle installed on the head cap. This buckling method has high requirements on the material, mechanical processing technology, etc. of the upper cover and the buckle. Once the material, mechanical processing technology, etc. are deviated, the upper cover is easy to fall off and be damaged from the buckle, thereby causing the probe to fall out of the accommodation cavity. In addition, the distance between the near-infrared probes is small (about 3 cm). In particular, when there are many near-infrared probes to be installed on the head cap, the operator is easy to touch the surrounding probe holders when disassembling the probes, causing the assembled probes to fall off or shift in position, seriously affecting the collection of near-infrared data. There are also some probe holders with more complex structural designs. For example, a near-infrared spectrum and EEG joint acquisition device disclosed in CN209863818U is realized by assembling and cooperating multiple components such as a clamp, a spring, a clamp ring, a wedge plate, a bracket, and a threaded connection structure to fix the probe on the head cap. The structure is complex and difficult to disassemble. Summary of the invention

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] The present application embodiment provides a probe fixing device for near-infrared brain function imaging equipment. Figure 1 and Figure 2As shown, the probe fixing device includes a cover assembly and a guide member 4. The cover assembly includes an upper cover 1 and a lower cover 2 that are detachably connected, and a receiving cavity 3 for at least receiving the probe 5 is formed between the upper cover 1 and the lower cover 2. The guide member 4 is slidably arranged in the receiving cavity 3, and acts on the probe 5. The guide member 4 has a first position and a second position in the receiving cavity 3. When the guide member 4 drives the probe 5 to be in the first position, the outer wall of the guide member 4 abuts against the inner wall of the lower edge of the upper cover 1. When the probe 5 drives the guide member 4 to move to the second position, the guide member 4 is misaligned with the lower edge of the upper cover 1; wherein, the lower cover 2 is used to be disassembled and assembled with the upper cover 1 when the guide member 4 is in the second position and the upper cover 1 is deformed by force, so as to move the probe 5 away from the receiving cavity 3 at least when the guide member 4 is in the second position.

[0031] Optionally, the above-mentioned accommodating cavity 3 may be partially or completely located in the upper cover 1. For example, part of the accommodating cavity 3 is located in the upper cover 1, and another part of the accommodating cavity 3 is located in the lower cover 2. For another example, all of the accommodating cavity 3 is located in the upper cover 1, and the lower cover 2 can be understood to be connectable to the lower edge of the upper cover 1.

[0032] Optionally, when the lower cover 2 is disassembled and assembled with the upper cover 1, it can be understood that it is detachably connected to the lower edge of the upper cover 1. When the guide member 4 is in the first position, the outer wall of the guide member 4 is against the inner wall of the lower edge of the upper cover 1. At this time, the lower edge of the upper cover 1 cannot be deformed even if it is subjected to force under the action of the guide member 4, so that the upper cover 1 and the lower cover 2 are in a non-disassembly state, thereby ensuring the connection stability of the upper cover 1 and the lower cover 2, thereby ensuring the installation firmness of the probe 5.

[0033] It is understandable that the upper cover 1 and the lower cover 2 are in a detachable state and a non-detachable state. When the guide member 4 is in the first position, the upper cover 1 and the lower cover 2 are in a non-detachable state, that is, at this time, the lower edge of the upper cover 1 cannot be deformed even if it is subjected to force under the action of the guide member 4, so that the lower cover 2 cannot be disassembled from the upper cover 1 that is deformed under force; when the guide member 4 is in the second position, the upper cover 1 and the lower cover 2 are in a detachable state, that is, at this time, the upper cover 1 can be deformed under the action of external force to achieve connection with the lower cover 2 and complete disassembly with the upper cover 1, especially the lower cover 2 can be disassembled from the upper cover 1, so that the probe 5 can be moved away from the accommodating cavity 3. Figure 1 , Figure 1 The guide member 4 shown in FIG. 1 is in the first position, at which time the upper cover 1 and the lower cover 2 are in a non-detachable state.

[0034] Optionally, the guide member 4 can be understood to be capable of linear sliding motion in the accommodating chamber 3 , the accommodating chamber 3 can be constructed in a cylindrical shape, and the guide member 4 can slide along the axial direction of the accommodating chamber 3 .

[0035] It is understandable that the guide member 4 in the first position is arranged closer to the lower edge of the upper cover 1 than the guide member 4 in the second position. Figure 1 As shown, Figure 1 The guide member 4 shown in the figure is in the first position. The guide member 4 in the first position can move toward the inside of the upper cover 1 to the second position under the action of the probe 5.

[0036] The above-mentioned second position can be understood as the guide member 4 being misaligned with the lower edge of the upper cover 1, so that the guide member 4 will not affect the position where the upper cover 1 is deformed by force. At this time, when external force acts on the upper cover 1, the upper cover 1 will be deformed by force to cooperate with the lower cover 2 for disassembly and assembly.

[0037] Optionally, the probe fixing device may further include a buckle connected to the lower cover 2. The near-infrared brain functional imaging device using the above-mentioned probe fixing device may include a pad for installing the probe fixing device. The lower cover 2 and the buckle are respectively placed on opposite sides of the pad, and the buckle can pass through the pad and be detachably connected to the lower cover 2 to confine the probe fixing device to the pad, thereby improving the installation stability of the probe fixing device.

[0038] The present application realizes that the guide member 4 and the probe 5 acting on each other can be stably placed in the accommodating chamber 3 formed by the upper cover 1 and the lower cover 2 through the detachable upper cover 1 and the lower cover 2, and when the guide member 4 is in the first position in the accommodating chamber 3, the outer wall of the guide member 4 is against the inner wall of the lower edge of the upper cover 1, and at this time, the lower edge of the upper cover 1 cannot be deformed even if it is stressed under the action of the guide member 4, so that the upper cover 1 and the lower cover 2 are in a non-detachable state to ensure the installation firmness of the probe 5, and the problem of the probe 5 being loosely fixed and easy to fall off due to the unstable connection between the upper cover 1 and the lower cover 2 will not occur, which is conducive to collecting more stable near-infrared signals. In addition, when the guide member 4 is in the second position in the accommodating chamber 3, and the upper cover 1 is deformed by stress, the lower cover 2 can be disassembled and assembled with the upper cover 1 to meet the needs of disassembling and assembling the probe 5 and the guide member 4, the structure is simple, and the above-mentioned disassembly and assembly method is also relatively simple and easy to operate.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, an elastic member 6 is provided in the accommodating cavity 3, and the elastic member 6 is used to apply a force to the guide member 4 to move it to the first position. By providing the elastic member 6, a force can be stably applied to the probe 5 during the use of the probe fixing device, so that the probe 5 can maintain a state of contacting with the subject's scalp, thereby ensuring the effectiveness of the near-infrared signal collected by the probe 5.

[0040] It is understandable that when the guide member 4 is in the first position, the elastic member 6 has a first length, and when the guide member 4 is in the second position, the elastic member 6 has a second length, and the first length is greater than the second length, that is, the guide member 4 in the second position will apply an extrusion force to the elastic member 6, so that the elastic member 6 is in a compressed state.

[0041] Optionally, the elastic member 6 has two opposite ends, one end of which abuts against the inner wall of the upper cover 1, and the other end abuts against the guide member 4. In some embodiments, the elastic member 6 may be specifically a compression spring.

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the guide member 4 has a guide column 41, the elastic member 6 is sleeved outside the guide column 41, and a through hole 11 is provided on the side of the upper cover 1 facing away from the lower cover 2 to allow one end of the guide column 41 to extend out.

[0043] By providing the elastic member 6, when the probe fixing device is worn on the head of the subject so that the probe 5 is subjected to the squeezing force of the head, the position of the probe 5 can be adaptively adjusted according to the head shape of the subject, thereby increasing the fit between the probe 5 and the scalp of the subject, thereby adjusting the quality of the near-infrared detection signal. Of course, when the probe 5 is subjected to the squeezing force of the head or other external force, the force applied by the probe 5 to the guide member 4 will not cause the guide member 4 to be too separated from the upper cover 1, and the guide member 4 can be kept in a state of being stably against the inner wall of the lower edge of the upper cover 1.

[0044] Optionally, the diameter of the through hole 11 may be equal to or slightly larger than the diameter of the guide column 41, so that the guide column 41 can smoothly pass through the through hole 11 and extend out of the upper cover 1, while also reducing the swing amplitude of the guide column 41, so that the probe 5 can more stably collect near-infrared signals in a direction perpendicular to the subject's head, thereby facilitating the collection of better near-infrared signals.

[0045] When the upper cover 1 and the lower cover 2 are in a non-detachable state, that is, the guide member 4 is in the first position, a force can be applied to the cable end of the probe 5, which is equivalent to applying a force to the probe 5. In this way, the guide member 4 in the first position moves linearly toward the inside of the upper cover 1 to the second position under the action of the probe 5, further realizing the switching of the detachable state of the upper cover 1 and the lower cover 2.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, the guide member 4 also has a cover body 42, the other end of the guide column 41 is connected to the cover body 42, the cover body 42 is arranged outside the probe 5, one end of the elastic member 6 abuts against the upper cover 1, and the other end abuts against the cover body 42. In this way, the cover body 42 can stably act on the probe 5, and the elastic member 6 can stably apply a force to the guide member 4 and the probe 5 under the action of the cover body 42.

[0047] Optionally, a gap may be formed between the cover body 42 and the probe 5, so as to stably install the probe 5 and prevent the probe 5 from swinging too much in the guide member 4, thereby affecting the accuracy of the detected near-infrared signal.

[0048] Optionally, the shape of the cover body 42 may be cylindrical, or may be other shapes that match the outer contour of the probe 5 , and the present application does not make any specific limitation thereto, as long as the probe 5 can be stably mounted.

[0049] In some embodiments, Figure 1 and Figure 2 As shown, one end of the upper cover 1 close to the lower cover 2 is constructed as an open end, and the guide member 4 and the probe 5 are installed in the accommodating cavity 3 located in the upper cover 1 through the open end. The open end of the upper cover 1 has a released state and a gathered state. When the guide member 4 is in the first position, the open end of the upper cover 1 is maintained in the released state, and when the guide member 4 is in the second position, the open end of the upper cover 1 can be in the gathered state.

[0050] In this way, the open end of the upper cover 1 can be switched between the released state and the gathered state by switching the position of the guide member 4, so that the open end of the upper cover 1 can be disassembled and assembled with the lower cover 2 when the open end is in the gathered state, and can be stably abutted against the lower cover 2 when the open end of the upper cover 1 is in the released state, thereby preventing the lower cover 2 from being forced out of the upper cover 1.

[0051] It is understandable that the upper cover 1 is in a released state when not subjected to external force, and at this time, it can interact with the guide member 4 in the first position, so that the upper cover 1 cannot be switched from the released state to the gathered state, so that the upper cover 1 and the lower cover 2 can be stably abutted, and the upper cover 1 and the lower cover 2 can be in a non-detachable state. The deformation of the upper cover 1 under force can be understood as when the guide member 4 is in the second position, the upper cover 1 is subjected to force, so that the open end of the upper cover 1 can be switched from the released state to the gathered state, thereby realizing the detachable state between the upper cover 1 and the lower cover 2.

[0052] Optionally, the upper cover 1 may be made of elastic material so as to be switchable between a released state and a gathered state.

[0053] Optionally, the upper cover 1 may be provided with a groove extending through to its open end, and the upper cover 1 may be forced into a gathered state by lifting the probe 5 during use, thereby enabling the open end of the upper cover 1 to smoothly switch between a released state and a gathered state.

[0054] In some embodiments, Figure 1 and Figure 2As shown, the lower cover 2 has a through cavity 21 for the probe 5 to pass through, and the inner wall of the through cavity 21 is snap-fitted with the outer wall of the upper cover 1, so that the lower cover 2 is mounted on the upper cover 1. In this way, the lower cover 2 can be sleeved on the outer side of the upper cover 1, so that the lower cover 2 and the upper cover 1 can be detachably connected. The above connection method is stable and simple, and is easy to process and install.

[0055] Optionally, the through cavity 21 may be annular in shape, and may include a first cavity and a second cavity extending vertically, wherein the diameter of the first cavity is greater than the diameter of the second cavity, wherein the first cavity is used to be snap-fitted with the outer wall of the upper cover 1, and the second cavity is sleeved outside the probe 5 and may be adapted to the outer contour size of the probe 5.

[0056] In some embodiments, Figure 1 and Figure 2 As shown, a groove is provided on the inner wall of the through cavity 21 of the lower cover 2, and a protrusion 12 matching the groove is provided on the outer wall of the upper cover 1. Through the cooperation between the groove of the lower cover 2 and the protrusion 12 on the upper cover 1, the upper cover 1 and the lower cover 2 can be stably installed, thereby improving the structural stability.

[0057] Optionally, the groove may be configured as a ring, the protrusion 12 may be configured as an arc, and the protrusion 12 may be inserted into the groove when the upper cover 1 is in a gathered state, so as to achieve installation between the upper cover 1 and the lower cover 2 .

[0058] In some embodiments, Figure 1 and Figure 2 As shown, a sliding portion 43 is provided on the outer wall of the guide member 4, and a sliding groove 13 adapted to the sliding portion 43 is provided on the upper cover 1. In this way, the guide member 4 can slide stably and linearly between the first position and the second position in the accommodating cavity 3 through the cooperation between the sliding portion 43 and the sliding groove 13.

[0059] Optionally, the slide groove 13 may be configured as a long strip, and the length direction thereof may be the same as the axial direction of the upper cover 1 .

[0060] Optionally, there may be at least two sliding parts 43 , and a plurality of sliding parts 43 are arranged around the guide member 4 , and the slide grooves 13 and the sliding parts 43 are arranged in a one-to-one correspondence, so as to further realize the stable sliding of the guide member 4 in the upper cover 1 .

[0061] In some embodiments, Figure 1 and Figure 2 As shown, a flange 14 is formed on the outer wall of the lower edge of the upper cover 1, and the flange 14 is used to receive force to switch the open end of the upper cover 1 from a released state to a gathered state. The flange 14 is provided to facilitate the operator to apply force to the lower edge of the upper cover 1, so as to facilitate the open end of the upper cover 1 to switch from a released state to a gathered state. In other embodiments, the operator can also directly apply force to the lower edge of the upper cover 1 to achieve the state switching of the open end of the upper cover 1.

[0062] Optionally, the flange 14 may be configured in an arc shape, and a notch may be formed at the flange 14 corresponding to the groove on the upper cover 1 .

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the cover body 42 is provided with a through slot 44 adapted to the outer contour of the probe 5. In this way, the probe 5 can be stably limited while being installed, ensuring the installation stability of the probe 5, and the cable end of the probe 5 can be exposed from the cover assembly.

[0064] Optionally, the through slot 44 on the cover body 42 may be arranged corresponding to the slot opened on the upper cover 1 for passing the probe 5 .

[0065] In some embodiments, the probe fixing device further includes a positioning member (not shown in the figure), which is installed at one end of the guide column 41 extending out of the through hole 11, and the positioning member can be used to position the probes 5 installed in each probe fixing device, so as to determine the position of the brain area measured by each probe 5. In a specific embodiment, the positioning member can be a sheet-like member, which can be installed on the end of the guide column 41 extending out of the through hole 11 by screws, and the structure is simple and stable.

[0066] The following will specifically introduce the method for using the probe fixing device of the present application: when the probe 5 and the guide member 4 are placed in the accommodating chamber 3, force can be applied to the cable end of the probe 5, such as lifting the cable end of the probe 5 upward, that is, applying force to the probe 5, the probe 5 drives the guide member 4 to move from the first position to the second position, and the guide member 4 squeezes the elastic member 6. At this time, the flange 14 on the upper cover 1 can be pressed to enable the open end of the upper cover 1 to switch from the released state to the gathered state, and force is applied to cause the groove set on the inner wall of the through cavity 21 of the lower cover 2 and the protrusion 12 on the outer wall of the upper cover 1 to disengage, and the lower cover 2 and the upper cover 1 are in a disengaged state. At this time, the probe 5 can be moved away from the accommodating chamber 3 to achieve the disassembly of the probe 5. When assembling the probe 5, the probe 5 is first placed in the accommodating cavity 3, and the cable end of the probe 5 is lifted. The probe 5 drives the guide member 4 to squeeze the elastic member 6. At this time, the guide member 4 is in the second position, and the flange 14 on the upper cover 1 is pressed to switch the open end of the upper cover 1 from the released state to the gathered state. The force is applied so that the raised portion 12 on the outer wall of the upper cover 1 is inserted into the groove provided on the inner wall of the through cavity 21 of the lower cover 2, and then the open end of the upper cover 1 is released to realize the installation of the probe 5. At this time, the outer wall of the guide member 4 corresponding to the force point of the upper cover 1 is in contact with the The inner walls of the lower edge of the upper cover 1 are abutted against each other, and when no force is applied to the probe 5, that is, when the guide member 4 is in the first position, even if the flange 14 on the upper cover 1 is pressed, the open end of the upper cover 1 cannot be switched from the released state to the gathered state, that is, when the guide member 4 is in the first position, the open end of the upper cover 1 remains in the released state, and the upper cover 1 and the lower cover 2 are in a non-disassembly state, which effectively ensures the installation firmness of the probe 5, and does not cause the probe 5 to be loosely fixed or easily fall off due to the unstable connection between the upper cover 1 and the lower cover 2.

[0067] The embodiment of the present application also provides a near-infrared brain function imaging device, which includes a probe 5 and the above-mentioned probe fixing device for the near-infrared brain function imaging device, and the probe fixing device is used to install the probe 5.

[0068] The near-infrared brain function imaging device using the above-mentioned probe fixing device realizes that the acting guide member 4 and the probe 5 can be stably placed in the accommodating cavity 3 formed by the upper cover 1 and the lower cover 2 through the detachably connected upper cover 1 and the lower cover 2, and when the guide member 4 is in the first position in the accommodating cavity 3, the outer wall of the guide member 4 abuts against the inner wall of the lower edge of the upper cover 1. At this time, the lower edge of the upper cover 1 cannot be deformed even if it is subjected to force under the action of the guide member 4, so that the upper cover 1 and the lower cover 2 are in a non-disassembly state to ensure the installation firmness of the probe 5, and the problem of the probe 5 being loosely fixed and easy to fall off due to the unstable connection between the upper cover 1 and the lower cover 2 will not occur. In addition, when the guide member 4 is in the second position in the accommodating cavity 3, and the upper cover 1 is deformed by force, the lower cover 2 can be disassembled and assembled with the upper cover 1 to meet the needs of disassembling and assembling the probe 5 and the guide member 4, and the above-mentioned disassembly and assembly method is relatively simple and easy to operate.

[0069] In addition, although exemplary embodiments have been described herein, the scope includes any and all embodiments based on the present application with equivalent elements, modifications, omissions, combinations (e.g., various embodiments intersecting schemes), adaptations or changes. The elements in the claims will be interpreted broadly based on the language used in the claims, and are not limited to the examples described in this specification or during the practice of the application, and the examples will be interpreted as non-exclusive.

[0070] The above description is intended to be illustrative rather than restrictive. For example, the above examples (or one or more of them) can be used in combination with each other. For example, those of ordinary skill in the art can use other embodiments when reading the above description. In addition, in the above-mentioned specific embodiments, various features can be grouped together to simplify the application. This should not be interpreted as an intention that a disclosed feature that does not require protection is necessary for any claim. On the contrary, the subject matter of the present application may be less than all the features of a specific disclosed embodiment. Thus, the claims are incorporated into the specific embodiments as examples or embodiments, wherein each claim is independently used as a separate embodiment, and it is considered that these embodiments can be combined with each other in various combinations or arrangements. The scope of the present application should be determined with reference to the full scope of the equivalent forms of the attached claims and these claims.

[0071] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
