Description

[0001] This application is a divisional application of Chinese invention patent application No. 202110631728.4, filed on June 7, 2021, entitled "A Head Optical Application Device, Transcranial Optical Modulation Device and Near-Infrared Device". Technical Field

[0002] This disclosure relates to the field of transcranial optical modulation technology, and more particularly to a head optical application device and a transcranial optical modulation device for use in a transcranial optical modulation device. Background Technology

[0003] In recent years, scientific research has discovered that light can be applied in medicine. For example, light can be used to modulate brain function for the research and treatment of neurological and psychological diseases, or to measure brain blood oxygenation signals for disease diagnosis and brain function analysis. However, in existing transcranial light modulation products, the light emitted by the light-emitting device is affected by the user's hair, leading to a reduced light propagation rate. This means that most of the light cannot reach the user's scalp, affecting the effectiveness of the transcranial light modulation product. Summary of the Invention

[0004] In view of the above-mentioned technical problems existing in the prior art, this disclosure provides a head optical application device and a transcranial light modulation device for use in a transcranial light modulation device. Without the need for a power drive device, it can enable an expandable element to push aside the hair of a user who is blocking the light, thereby improving the light propagation rate.

[0005] According to the first aspect of this disclosure, a head optical application device for a transcranial optical modulation device is provided. The head optical application device includes a support member, an optical member, an expandable member, and a transmission mechanism. The support member is configured to mount the optical member; the optical member is configured to transmit light to the scalp; the expandable member is disposed on the support member, wherein the expandable member is configured to expand or converge its distal end under the action of a human-applied force from the surrounding environment; the transmission mechanism is disposed between the support member and the expandable member, and the transmission mechanism is configured to convert the rotational movement of the support member into the expansion or convergence of the distal ends of the expandable member.

[0006] According to a second aspect of this disclosure, a transcranial optical modulation device is also provided, comprising a plurality of head optical application devices as described above for use on a transcranial optical modulation device, and a housing for mounting the plurality of head optical application devices.

[0007] Compared with the prior art, the beneficial effects of the embodiments of this disclosure are as follows: This disclosure, by using forces induced by the surrounding environment to cause the expandable components to converge or expand relative to each other on the distal side of the optical component, enables the distal end of the expandable component to be inserted into the user's hair in a converged state without the need for an electrically driven device. After insertion, the distal end of the expandable component can be deployed to push aside hair blocking light, thus improving the problem of low light propagation caused by hair obstruction. Furthermore, it improves the usability of transcranial light modulation devices using this head optical application device, allowing the light emitted from the optical component of the optical application device to directly illuminate the user's scalp and penetrate the skull, thereby better improving brain function.

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific examples, but these are not intended to limit the scope of this disclosure.

Words such as "including" or "contains" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, this relative positional relationship may also change accordingly.

[0030] In this disclosure, when a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may be not directly connected to the other devices but have an intermediary device.

[0031] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, 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.

[0032] 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.

[0033] According to some embodiments of this disclosure, a head optical application device 100 is provided, such as... Figures 1 to 13 As shown, the head optical application device 100 includes a support member 110, an optical member 120, and an expandable member 130. The support member 110 is configured to mount the optical member 120. The optical member 120 is configured to transmit light to the scalp. The expandable member 130 is disposed on the support member 110, wherein the expandable member 130 is configured to expand or converge its distal end under the action of forces caused by the surrounding environment.

[0034] It should be noted that the device equipped with the above-mentioned head optical application device 100 can be worn on the user's head by the operator. The above-mentioned optical component 120 corresponds to the user's scalp. In this disclosure, the proximal side is the side that is closer to the operator and farther away from the user's scalp, and the distal side is the side that is closer to the user's scalp. The proximal end is the end that is farther away from the user's scalp, and the distal end is the end that is closer to the user's scalp. The proximal and distal sides mentioned below have the same meaning.

[0035] Specifically, the aforementioned head optical application device 100 includes, but is not limited to, applications in transcranial light modulation devices 200. The aforementioned optical component 120 has the function of emitting light, which can be infrared light capable of penetrating the skull. The optical component 120 can be any light-emitting optical component 120, such as an LED, fiber optic cable, or laser. When the head optical application device 100 is applied in a transcranial light modulation product, the optical component 120 is mainly used to emit light onto the scalp to improve the user's brain function. This disclosure does not specifically limit the function of the optical component 120 or the compatibility between multiple optical components 120. Optical components 120 with corresponding functions can be adopted according to the technical field in which the head optical application device 100 is applied to improve the irradiation rate of the user's scalp.

[0036] This disclosure does not specifically limit the number and structure of the expandable elements 130, as long as they can separate the hair between the optical component 120 and the user's scalp. Preferably, the expandable elements 130 can be arranged around the optical component 120 or in pairs on opposite sides of the optical component 120 to achieve a better hair-splitting effect, allowing the light emitted by the optical component 120 to directly illuminate the scalp. The expandable elements 130 can be any shape or structure capable of achieving the hair-splitting effect, such as comb-like, arc-shaped, triangular, or rectangular, etc. The structures of the expandable elements 130 in the accompanying drawings are merely examples, and this disclosure is not limited thereto.

[0037] Specifically, the head optical application device 100 may include at least two expandable members 130, or only one expandable member 130. When the head optical application device 100 includes two expandable members 130, the distal ends of each expandable member 130 can unfold or converge under the action of forces caused by the surrounding environment, and this unfolding or convergence is related to the relative positional relationship between the expandable members 130. When the head optical application device 100 includes only one expandable member 130, the expandable member 130 may be composed of multiple claw-shaped structures, which can unfold and converge. The number of expandable members 130 can be set based on structural selection in conjunction with specific embodiments. The following description uses at least two expandable members 130 as an example, but this disclosure is not limited thereto.

[0038] Specifically, each expandable member 130 has a converged state where its distal ends are close together, and an unfolded state where its distal ends are spread apart. When the device equipped with the aforementioned head optical application device 100 is worn on the user's head, the distal ends of each expandable member 130 are in the converged state, and the cross-sectional area of ​​the distal ends of each expandable member 130 can be minimized to facilitate insertion into the hair. After the user wears the aforementioned device, the distal ends of the aforementioned expandable members 130 maintain a close fit with the user's scalp, so that under the action of forces caused by the surrounding environment, the distal ends of each expandable member 130 spread apart. When it is in the unfolded state, the expandable member 130 can drive the hair in the area irradiated by the optical component 120 to move away from that area, thereby achieving the purpose of parting the hair and increasing the light transmission rate.

[0039] In some embodiments, the forces caused by the surrounding environment can be understood as forces resulting from changes in the temperature, humidity, etc., of the surrounding environment, or forces manually applied by an operator. It is important to emphasize that these forces are not caused by electrically driven equipment. Although electrically driven systems can control the deployment or folding of the expandable component 130, they require a power source, resulting in complex structures and high costs. The electrically driven equipment can be understood as a pneumatic mechanism, an electromagnetic control mechanism, or other equipment that can operate with electricity. Changes in the temperature, humidity, etc., of the surrounding environment can cause structural changes in the supporting member 110 and / or the expandable component 130.

[0040] Specifically, the aforementioned expandable component 130 can be connected to the load-bearing member 110 via a rotatable connection, a detachable connection, or other components. The aforementioned rotatable connection may include, but is not limited to, a pivot connection, which enables the expandable component 130 to unfold or fold under the force caused by the surrounding environment.

[0041] Specifically, the support member 110 and / or the expandable member 130 can be made of a material whose structure can change with temperature. For example, when the ambient temperature is within a first preset temperature range, the support surface of the support member 110 with the expandable member 130 can form a cavity facing proximally. When the user wears the head optical application device 100, the distal ends of each expandable member 130 are brought together against the user's scalp. When the ambient temperature reaches a second preset temperature, the structure of the support member 110 changes due to the ambient temperature. The support surface with the expandable member 130 gradually changes from being concave proximally to convex outward, so that each expandable member 130 can gradually expand outward and transform into an unfolded state while pressing against the scalp, thereby separating the hair. The first preset temperature can be room temperature (e.g., 18 to 25 degrees Celsius), and the second preset temperature is a temperature higher than room temperature, corresponding to the temperature at which the material used in the support member 110 and / or the expandable member 130 can deform. The following section will provide a detailed description of an embodiment in which the structure of the expandable element 130 can change with temperature, which will not be elaborated upon here.

[0042] In some embodiments, when the various expandable members 130 are in the converged state, each expandable member 130 may be arranged in a conical shape, and the tip of the cone is arranged in relation to the light-emitting or light-receiving optical path of the optical member 120, for example, arranged on the optical path, so that when the various expandable members 130 are converted to the unfolded state, the hair on the optical path of the optical member 120 is pushed aside to improve the light propagation rate along the optical path relative to the scalp.

[0043] Specifically, this disclosure does not specifically limit the shape and material of the aforementioned support member 110. It can be any shape, such as a circular plate, rectangular plate, or block, as long as it can support the optical member 120 and the expandable member 130. The structural design of the aforementioned support member 110 should minimize its space occupation and be made of materials with high structural strength and light weight, so as to maintain stable installation while reducing the pressure on the user's head during wear, thus improving the user experience. (Specific details can be found in conjunction with...) Figures 1 to 4 As shown, Figures 1 to 2 The load-bearing components 110 shown are all rectangular plates. Figures 3 to 4 The load-bearing members 110 shown are all in the shape of circular plates. It is understood that the structure of the load-bearing members 110 can be selectively designed according to the specific structure of the head optical application device 100. This disclosure does not make any specific limitations in this regard.

[0044] This disclosure enables the various expandable components 130 to converge or expand towards each other on the distal side of the optical component 120 under the action of forces caused by the surrounding environment. Without the need for an electric drive device, the distal ends of each expandable component 130 can be inserted into the user's hair in a converged state, and after insertion, the distal ends of the expandable components 130 can be expanded to push aside the hair blocking the light, thus improving the problem of low light propagation caused by hair blocking.

[0045] Furthermore, it can improve the performance of the transcranial light modulation device 200 using the head optical application device 100, so that the light emitted by the optical component 120 of the optical application device can directly irradiate the user's scalp and penetrate the skull, thereby better improving brain function.

[0046] In some embodiments, the expandable element 130 is made of a first deformable material and, under the action of deformation stress of the first deformable material caused by the surrounding environment, switches between a first configuration that converges at the distal end and a second configuration that expands at the distal end.

[0047] Specifically, the first deformable material can be a memory material, such as a shape memory polymer, a shape memory metal (such as a nickel-titanium shape memory alloy), etc. The memory material can be molded into a configuration under the second preset temperature, transformed into another configuration under the first preset temperature, and then transformed back into the previous configuration when the surrounding environment returns to the second preset temperature.

[0048] The following explanation uses the example of expandable component 130 using a shape memory material. If expandable component 130 is made of a shape memory alloy with a two-way memory effect, each expandable component 130 can be in a clustered state at low temperatures. The first configuration of each expandable component 130 can be understood as being associated with this clustered state. After the ambient temperature rises to the temperature at which the shape memory alloy can deform, each expandable component 130 deforms and transforms into an expanded state due to its own material properties. The second configuration can be understood as being associated with this expanded state.

[0049] In some embodiments, when the first deformable material used in each expandable element 130 deforms due to temperature, the temperature change of the surrounding environment can be provided by a heating element, by the heat generated after the optical component 120 operates, or by other devices on the equipment employing the head optical application device 100 that can raise the temperature of the surrounding environment. This disclosure does not specifically limit this. Preferably, the temperature of the surrounding environment is provided by the heat generated after the optical component 120 operates, so as to utilize the temperature rise effect generated by the operation of the optical component 120 to cause each expandable element 130 to deform after the optical component 120 operates, changing from the first configuration to the second configuration. After the optical component 120 is no longer in use, the ambient temperature gradually decreases, causing each expandable element 130 to gradually change from the second configuration to the first configuration. No other heating element is needed to provide heat, and no additional operation by the operator is required to switch the expandable element 130 between the two configurations, which can reduce costs and facilitate the use of the operator.

[0050] In some embodiments, the first deformable material can be a shape memory material, which can be a partially crystalline linear polymer formed by polymerizing three monomer raw materials: isocyanate, polyol and chain extender. It can form a reversible transformation between a glassy state and a rubbery state, and can recover its original shape when heated to 40 degrees Celsius. The expandable part 130 can be converted between the two configurations without the need for other means, making the structure of the expandable part 130 simpler and the cost lower.

[0051] In some embodiments, the first deformable material can be a photosensitive shape memory polymer containing photochromic genes. The light emitted by the optical component 120 can be used to convert the expandable component 130 from a first configuration to a second configuration. That is, the light emitted by the optical component 120 can be used for treatment or measurement, and can also be used to bring the distal ends of each expandable component 130 together or expand them without the need for additional structural design. This makes the structure of the head optical application device 100 simpler and less expensive.

[0052] The expandable part 130 made of the above-mentioned shape memory polymer is lighter and cheaper than the expandable part 130 made of shape memory alloy for the same size, and the expandable part 130 made of the above-mentioned shape memory polymer has a large deformation and repeatable deformation effect.

[0053] The above description uses a memory material that can deform under the influence of temperature and light as an example, but this disclosure is not limited thereto. The aforementioned memory material can be any material that allows the expandable element 130 to switch between two configurations using one or more methods such as heat, electricity, light, and magnetism. The expandable element 130 can be made of at least one of the aforementioned memory materials. The device that satisfies the condition that the memory material can deform, or that achieves this condition, can be provided by the head optical application device 100 or a device equipped with the head optical application device 100. This disclosure does not specifically limit this, as long as it enables each expandable element 130 to switch between an expanded state and a converged state.

[0054] Furthermore, the aforementioned expandable component 130 can be entirely made of the first deformable material, or it can be partially made of the first deformable material. Preferably, when a portion of the expandable component 130 is made of the first deformable material, the distal side of the expandable component 130 can be made of the first deformable material. In addition, when the expandable component 130 is made of shape memory alloy, it can be covered with a layer of soft material to improve the user's comfort when the expandable component 130 comes into contact with the scalp.

[0055] In some embodiments, the expandable element 130 is configured to expand or converge its distal end under the action of artificially applied forces from the surrounding environment.

[0056] Specifically, the aforementioned artificially applied force from the surrounding environment can act on the supporting member 110, enabling the supporting member 110 to move in a first direction toward the scalp and / or in a second direction away from the scalp, or to move up and down along the direction of hair growth, or to rotate relative to the user's scalp. The following will describe in detail several specific embodiments of how the supporting member 110 performs different movements to allow the distal ends of the various expandable members 130 to unfold or converge with each other.

[0057] In some embodiments described below, the head optical application device 100 may further include a transmission mechanism 140 disposed between the support member 110 and the expandable member 130. The transmission mechanism 140 is configured to convert the translational or rotational movement of the support member 110 into the expansion or contraction of the distal ends of the expandable member 130. The translational or rotational movement of the support member 110 can be transmitted through the transmission mechanism 140, enabling the expandable member 130 to switch between an expanded state and a contracted state.

[0058] Specifically, the supporting member 110 is further configured to be able to move in a first direction toward the distal side under the action of a manually applied force; or to be able to move up and down in a second direction of hair growth under the action of a manually applied force. The aforementioned translational movement includes movement along the first direction and movement along the second direction.

[0059] Example 1

[0060] like Figures 1 to 5 As shown in the figure, the load-bearing members 110 shown in the figure can all cause the distal ends of the expandable members 130 to expand or converge with each other under the action of artificial forces applied by the surrounding environment.

[0061] Combination Figure 1 and Figure 2 When the device equipped with the aforementioned head optical application device 100 is worn on the user's head, Figure 1 and Figure 2 The expandable element 130 rests against the user's scalp, and the operator can apply force to the support member 110 to move the support member 110 in a first direction toward the scalp. In some embodiments, such as Figure 1 and Figure 2 As shown, the transmission mechanism 140 includes a first transmission part 141 and a second transmission part 142 pivotally connected to opposite sides of the bearing member 110, and at least two expandable members 130, which are respectively disposed inside the first transmission part 141 and the second transmission part 142. Each of the first transmission part 141 and the second transmission part 142 is configured to expand outward as the bearing member 110 translates in a first direction, so that the expandable members 130 located thereon unfold each other.

[0062] Specifically, such as Figure 1 and Figure 2 As shown, the shapes of the first transmission part 141 and the second transmission part 142 can be in a relatively extended state whether each expandable member 130 is in a converged state or an extended state. So that when each expandable member 130 is in a converged state, the first transmission part 141 and the second transmission part 142 can move in the first direction under the action of the supporting member 110. Figure 1 The state shown gradually unfolds to Figure 2 The unfolded state shown in the figure is such that the distal ends of each expandable element 130 are moved away from each other.

[0063] In some embodiments, such as Figure 1 and Figure 2As shown, the first transmission part 141 and the second transmission part 142 can both be arc-shaped plates. The arc design of the arc plate should facilitate the gradual outward expansion of the two when subjected to the force in the first direction. The arc-shaped plate structure increases the structural strength of the transmission mechanism 140, so that when the first transmission part 141 and the second transmission part 142 are subjected to force, they can smoothly drive the far ends of each expandable member 130 away from each other.

[0064] In some embodiments, a plurality of expandable members 130 disposed on the first transmission part 141 may be integrally formed on the first transmission part 141, and a plurality of expandable members 130 disposed on the second transmission part 142 may be integrally formed on the second transmission part 142, so as to maintain the relative positional relationship between the transmission member and the expandable member 130, and to ensure the structural strength of the connection between the two.

[0065] In some embodiments, the expandable member 130 is made of a second deformable material, and the support member 110 is further configured such that when it moves in a first direction toward the distal side under the action of a human-applied force, the distal ends of the expandable member 130 are deformed from being brought together to being unfolded.

[0066] Specifically, the second deformable material can be the same as or a different material from the first deformable material. When they are different, the second deformable material can be a material capable of elastic deformation, and can be a metallic or non-metallic material, such as phosphor bronze, beryllium bronze, manganese steel, etc. among metallic materials, and rubber, silicone, etc. among non-metallic materials. This disclosure does not make specific limitations in this regard; the second deformable material only needs to be able to deform under force and return to its state before the force is removed.

[0067] like Figure 1 and Figure 2 As shown, Figure 1 The diagram shows six expandable elements 130, but multiple expandable elements 130 can be provided along the first direction. The diagram only illustrates an example with three expandable elements 130 on one side of the optical component 120; this disclosure is not limited to this. Figure 1 As shown, the expansion bodies 134 of the expandable members 130 located on opposite sides of the optical member 120 are shaped to expand outward from each other, so as to facilitate the tendency of the paired expandable members 130 to move into an unfolded state.

[0068] Specifically, in combination Figures 3 to 5 , Figures 3 to 5All expandable components 130 can be made of a second deformable material. When the device equipped with the head optical application device 100 is worn on the user's head, there is a certain gap between the distal end of each expandable component 130 and the user's scalp to avoid the scalp acting on the expandable component 130 to cause irregular deformation when worn. After the device is worn, the operator can act on the support member 110 to make it move in the first direction. At this time, each expandable component 130 is squeezed between the support member 110 and the scalp. Each expandable component 130 will undergo elastic deformation and gradually transform into an unfolded state to push aside the hair during the unfolding process.

[0069] In some embodiments, such as Figure 3 As shown, there are at least two expandable members 130. Each expandable member 130 includes a first body 136 disposed on the support member 110 and a second body 137 disposed on the distal side of the first body 136. The proximal ends of the second body 137 of each expandable member 130 abut each other and gradually expand toward their distal ends.

[0070] Specifically, the second body 137 extends outward along the length of the first body 136. The proximal ends of the multiple second bodies 137 can be brought together by magnetic components or elastic bands, and the distal ends of the multiple second bodies 137 are relatively unfolded relative to their proximal ends, which facilitates the transformation of the second body 137 into an unfolded state. This allows the hair to be easily parted, thus achieving a better hair-parting effect.

[0071] In some embodiments, the first body 136 and the second body 137 may be integrally formed or overmolded, or the first body 136 and the second body 137 may be connected by adhesive bonding or other connection methods. This disclosure does not specifically limit the specifics of these methods.

[0072] In some embodiments, the second body 137 is closer to the user's scalp than the first body 136. The second body 137 can be made of a material with relatively high flexibility to ensure comfort when it comes into contact with the user's scalp. The first body 136 is made of a material with relatively high hardness to further ensure that the expandable part 130 can be smoothly expanded during the expansion process without bending inward or to the side, which would affect the hair-pulling effect.

[0073] In some embodiments, such as Figure 5 As shown, the distal end of the expandable member 130 is provided with a guide surface 133, which is configured such that the force applied to the distal end of the expandable member 130 for unfolding is greater than the force applied to the distal end of the expandable member 130 for gathering, so that the expandable member 130 can unfold smoothly when it is squeezed between the support member 110 and the scalp.

[0074] Specifically, the aforementioned guide surface 133 can be made of a smooth material to reduce friction between the expandable part 130 and the scalp, which is beneficial for the expandable part 130 to unfold relatively.

[0075] Specifically, such as Figure 5 As shown, the aforementioned expandable members 130 are arranged in pairs on opposite sides of the optical component 120, and a first bracket 171 is provided between the paired expandable members 130. The first bracket 171 is arranged in a one-to-one correspondence with the optical component 120, and the first bracket 171 forms a communicating cavity in which the optical component 120 can be embedded. The first bracket 171 is constructed such that when each expandable member 130 is subjected to force, a pushing force is applied to each expandable member 130 to make it expand outward. The above structure can achieve a better hair-pulling effect, allowing more light emitted by the optical component 120 to illuminate the scalp, further improving the illumination rate of the head.

[0076] In some embodiments, the optical component 120 may be one or more. When there are multiple optical components 120 (e.g.) Figure 4 As shown, the supporting member 110 is a circular plate, and there are multiple optical members 120. One optical member 120 is located in the middle of the supporting member 110, and the other multiple optical members 120 are arranged around the optical member 120 located in the middle. Multiple expandable members 130 are arranged around the optical member 120 located in the middle. The supporting member 110 also has a second support 172 arranged around the optical member 120. The second support 172 is configured to apply a pushing force to each expandable member 130 when each expandable member 130 is subjected to force, so as to facilitate the parting of hair. In some embodiments, the expandable members 130 may be arranged around the multiple optical members 120.

[0077] Specifically, such as Figure 2 As shown, a torsion member 160 is provided at the pivot point between the expandable member 130 and the supporting member 110 to bring the distal ends of the oppositely arranged expandable members 130 closer together. This torsion member 160 can be a torsion spring. After the head optical application device 100 is used, there is no need to manually reset each expandable member 130. Under the action of the torsion member 160, the distal ends of each expandable member 130 will reset and convert to a converged state.

[0078] Example 2

[0079] like Figures 6 to 9As shown, the supporting member 110 includes a mounting plate 111 for mounting the optical member 120, at least two expandable members 130, and each expandable member 130 is pivotally connected to the mounting plate 111 and distributed on opposite sides of the optical member 120. The transmission mechanism 140 includes a pair of sliding grooves 143 extending along the hair growth direction and a third transmission part 144 and a fourth transmission part 145 sliding along the sliding grooves 143. The distance between the pair of sliding grooves 143 gradually narrows along the hair growth direction. The end of the third transmission part 144 and the fourth transmission part 145 facing away from the sliding groove 143 respectively abuts against the proximal side of the expandable member 130.

[0080] Specifically, Figure 6 and Figure 7 The diagram shows the usage state of the head optical application device 100 with the user's upper body in an upright position. Figure 6 The direction shown from top to bottom is the direction of hair growth.

[0081] Specifically, the third transmission part 144 and the fourth transmission part 145 can move relatively closer or relatively farther apart depending on the spacing of the paired slide grooves 143. For example... Figure 6 As shown, the aforementioned head optical application device 100 is in an unforced state. At this time, the various expandable components 130 are in a converged state, and the spacing between the paired slides 143 is also relatively large. When force is applied to the mounting plate 111, causing the mounting plate 111 and the expandable components 130 to move in the direction of hair growth (e.g. Figure 7 As shown, due to the gradual decrease in the spacing between the paired grooves 143, the third transmission part 144 and the fourth transmission part 145 move towards each other. The two act on the proximal side of the expandable member 130 respectively, causing the expandable member 130 to pivot to the proximal side to converge with each other and the distal side to expand with each other, so as to part the hair in the corresponding area.

[0082] Specifically, the expandable component 130 can be any shape or structure capable of achieving a hair-flicking effect, such as an arc-shaped plate, a comb-shaped plate, a triangular plate, a rectangular plate, or other shapes. Figure 6 and Figure 7 The rectangular plate shape of the expandable element 130 shown is merely an example, and this disclosure is not limited thereto.

[0083] Specifically, such as Figure 8 As shown, a torsion member 160 is provided at the pivot point between the expandable member 130 and the supporting member 110 to bring the distal ends of the oppositely arranged expandable members 130 closer together. This torsion member 160 can be a torsion spring. After the head optical application device 100 is used, there is no need to manually reset each expandable member 130. Under the action of the torsion member 160, the expandable member 130 and the mounting plate 111 will be reset.

[0084] In some embodiments, the support member 110 further includes a first frame 112, a mounting plate 111 is disposed on the far side of the first frame 112, the proximal side of the first frame 112 is configured to receive a force applied by human intervention, and through holes are respectively provided on opposite sides of the first frame 112 to allow the third transmission part 144 and the fourth transmission part 145 to pass through.

[0085] Specifically, the proximal side of the first frame 112 can pass through the housing 210 of the device on which the head optical application device 100 is installed. When the device is worn on the user's head, the operator can move the part of the first frame 112 exposed outside the housing 210.

[0086] Specifically, the first frame 112 may have a U-shaped body, including two opposing vertical plates and a horizontal plate connecting the two vertical plates. The through holes are respectively provided on the two vertical plates, and the two through holes are arranged opposite each other. By providing the through holes, the third transmission unit 144 and the fourth transmission unit 145 can be radially limited, allowing the third transmission unit 144 and the fourth transmission unit 145 to stably extend and retract along their axial direction. The horizontal plate is configured to receive manually applied force, facilitating the operator's application of force.

[0087] In some embodiments, such as Figure 8 and Figure 9 As shown, Figure 9 The diagram shows a cross-sectional view of either the third transmission unit 144 or the fourth transmission unit 145. Each of the third transmission unit 144 and the fourth transmission unit 145 includes a sleeve 151, a buffer spring 152 located within the sleeve 151, and spherical portions 153 abutting against both ends of the buffer spring 152. One of the two spherical portions 153 is embedded in a groove 143, and the other abuts against an expandable member 130. The spherical portion 153 is partially embedded in the groove 143, and its structural design reduces friction between it and the groove 143, facilitating the sliding of the third transmission unit 144 and the fourth transmission unit 145 along the groove 143.

[0088] Specifically, the aforementioned buffer spring 152 is used to apply a force to the two spherical portions 153 to move them apart. The two ends of the aforementioned sleeve 151 can be configured to prevent the spherical portions 153 from completely disengaging from the sleeve 151.

[0089] Example 3

[0090] like Figure 10 and Figure 11As shown, the supporting member 110 includes a second frame 113 and a first rotating part 114 rotatably disposed on the second frame 113. There are at least two expandable members 130, each of which is pivotally connected to the second frame 113 and distributed on opposite sides of the optical member 120. The near-inner surface of each expandable member 130 abuts against the circumferential outer wall of the first rotating part 114. The first rotating part 114 is configured to rotate to drive the near-side ends of the expandable members 130 located on opposite sides of the optical member 120 to expand or converge with each other.

[0091] Specifically, the aforementioned first rotating part 114 may have two opposing sides with a spacing of a first length, and another two opposing sides with a spacing of a second length, wherein the first length is greater than the second length. When the two sides with a spacing of the first length respectively abut against the proximal side of the oppositely arranged expandable members 130, each expandable member 130 is in a converged state (e.g., Figure 10 As shown), when the operator rotates the first rotating part 114 so that the two sides with a spacing of the second length respectively abut against the expandable member 130, each expandable member 130 gradually changes from the above-mentioned converged state to the unfolded state (as shown). Figure 11 (As shown).

[0092] Specifically, the shape of the cross-section of the first rotating part 114 can be elliptical, irregular arc, rectangular, etc., and this disclosure does not impose specific limitations on it. Preferably, as Figure 11 As shown, the cross-sectional shape of the first rotating part 114 is elliptical, which allows the expandable part 130 to gradually unfold from the folded state, improving the user experience.

[0093] In some embodiments, the second frame 113 may have a first substrate 175 and a third support 173 disposed on the first substrate 175. An expandable member 130 is pivotally connected to the third support 173. An optical component 120 is disposed between the two expandable members 130 and located on the third support 173. A first rotating part 114 is disposed between the third support 173 and the first substrate 175. The above structure is compact, which helps to reduce the space occupied by the product, and the design is reasonable.

[0094] In some embodiments, such as Figure 10 As shown, the pivot joint between the expandable member 130 and the supporting member 110 may be provided with a torsion member 160 that moves the distal ends of the oppositely arranged expandable member 130 away from each other, so that the proximal end of the expandable member 130 can maintain a tight contact with the outer peripheral surface of the first rotating shaft under the action of the torsion member 160.

[0095] In some embodiments, such as Figure 10 and Figure 11As shown, the first rotating part 114 has an arc-shaped circumferential surface, and the arc-shaped circumferential surface is configured such that when the first rotating part 114 rotates, the proximal ends of each expandable member 130 that abuts against it move closer or further apart.

[0096] Specifically, the shape of the aforementioned arc-shaped circumferential surface can be elliptical, and a smooth layer can be provided on the outside of the arc-shaped circumferential surface to facilitate the sliding of the expandable member 130 along the arc-shaped circumferential surface.

[0097] In some embodiments, such as Figure 10 and Figure 11 As shown, a limiting part 115 protrudes from the second frame 113, and the first rotating part 114 has a limiting groove 116 adapted to the limiting part 115 so that when the limiting part 115 is assembled in the limiting groove 116, the distal ends of each expandable member 130 remain in a gathered state.

[0098] Specifically, the aforementioned limiting part 115 can be a protruding post, and the limiting groove 116 can be an arc-shaped groove adapted to it. The two arc-shaped grooves are respectively located on two opposite sides with a distance equal to the aforementioned first length. The protruding post can be integrally formed on the second frame 113. The structural design of the aforementioned limiting groove 116 and limiting part 115 enables the first rotating part 114 to be held in the converged position of each expandable member 130, and the first rotating part 114 can only rotate after being subjected to external force.

[0099] In some embodiments, each expandable member 130 has an arc-shaped protrusion 131 on its near-inner side to fit against the circumferential outer wall of the first rotating part 114. The structural design of the arc-shaped protrusion 131 can reduce the contact friction between the expandable member 130 and the first rotating part 114, which is beneficial for the expandable member 130 to switch between the folded state and the unfolded state.

[0100] Example 4

[0101] In some embodiments, such as Figure 12 and Figure 13 As shown, there are at least two expandable members 130. The supporting member 110 includes a third frame 117 and a second rotating part 118 rotatably disposed on the third frame 117. Each expandable member 130 is disposed on opposite sides of the optical member 120, and each expandable member 130 is slidably disposed on the third frame 117. The near-inner surface of each expandable member 130 abuts against the circumferential outer wall of the second rotating part 118. The second rotating part 118 is configured to push the distal ends of the expandable members 130 located on opposite sides of the optical member 120 to expand or converge with each other by rotation.

[0102] Specifically, the second rotating part 118 may have two opposing sides spaced by a third length, and another two opposing sides spaced by a fourth length, wherein the third length is greater than the fourth length. When the two sides spaced by the third length respectively abut against the proximal sides of the oppositely arranged expandable members 130, each expandable member 130 is in a converged state (e.g., Figure 12 As shown), when the operator rotates the second rotating part 118 so that the two sides with a spacing of the fourth length respectively abut against the expandable member 130, each expandable member 130 gradually changes from the above-mentioned converged state to the unfolded state (as shown). Figure 13 (As shown).

[0103] Specifically, the cross-sectional shape of the second rotating part 118 can be elliptical, irregular arc, rectangular, etc., and this disclosure does not impose specific limitations on it. Preferably, as Figure 13 As shown, the cross-sectional shape of the second rotating part 118 is elliptical, which allows the expandable part 130 to gradually unfold from the folded state, improving the user experience.

[0104] In some embodiments, such as Figure 12 and Figure 13 As shown, the third frame 117 may have a second substrate 176 and a fourth support 174 disposed on the second substrate 176. An expandable member 130 is slidably disposed on the fourth support 174. An optical component 120 is disposed between two expandable members 130 and on the fourth support 174. A second rotating part 118 is disposed between the fourth support 174 and the second substrate 176. This structure is compact, which helps reduce the product's footprint, and the design is reasonable.

[0105] In some embodiments, such as Figure 12 and Figure 13 As shown, the transmission mechanism 140 includes two telescopic rods 146 mounted on the third frame 117, with the inner opposite ends of the two telescopic rods 146 abutting against the opposite sides of the expandable members 130 located on both sides.

[0106] Specifically, the extension and retraction directions of the two telescopic rods 146 are the same as the sliding direction of the expandable member 130, and the two telescopic rods 146 are located on opposite sides of the two expandable members 130. The telescopic rods 146 are used to apply a force to the expandable member 130 to convert it into a convergent state, so as to push the two expandable members 130 to move towards each other, so that the near-inner side of the expandable member 130 abuts against the outer wall of the second rotating part 118.

[0107] Specifically, the telescopic rods 146 and the expandable components 130 are arranged in a one-to-one correspondence so that each telescopic rod 146 can stably act on each expandable component 130.

[0108] In some embodiments, such as Figure 12 and Figure 13 As shown, an insertion portion 132 is formed on the distal side of the expandable member 130, and the insertion portions 132 of the expandable member 130, which are disposed opposite to each other on both sides of the optical member 120, can fit together.

[0109] Specifically, such as Figure 12 As shown, the insertion portions 132 of the two oppositely arranged extension members can fit tightly together when the extension member 130 is in the gathered state, and the two are pointed after being gathered together, which is conducive to the insertion of the extension member into the scalp in the gathered state.

[0110] In some embodiments, the expandable member 130 is pivotally connected to the support member 110, and the pivot point is provided with a torsion member 160 that causes the distal ends of the oppositely arranged expandable members 130 to move closer or further apart.

[0111] Specifically, such as Figure 7 and Figure 8 As shown, in Embodiment 2, the aforementioned torsion member 160 is used to bring the distal ends of the oppositely arranged extendable members 130 closer together. Figure 10 and Figure 11 As shown, in Embodiment 3, the torsion member 160 is used to move the distal ends of the oppositely arranged expandable members 130 away from each other. The force exerted by the torsion member 160 on the expandable members 130 can be set according to the specific structure of each embodiment.

[0112] In some embodiments, there are multiple optical components 120, which are arranged sequentially along a fifth length direction, and multiple expandable members 130 are arranged in pairs on opposite sides of the optical components 120 along the fifth length direction. Furthermore, the multiple optical components 120 can be arranged along a first width direction perpendicular to the fifth length direction.

[0113] Specifically, such as Figure 1 and Figure 2 As shown, the supporting member 110 is a rectangular plate with a fifth length direction. Multiple optical members 120 are sequentially arranged along the fifth length direction, and multiple expandable members 130 can be arranged in pairs on opposite sides of the optical members 120 along the fifth length direction. This disclosure does not specifically limit the number of expandable members 130, the number of optical members 120, or their arrangement; the design is based on the application scenario of the head optical application device 100, aiming to achieve optimal light emission and hair-parting effects. Furthermore, the supporting member 110 may have a curved surface adapted to the curvature of the user's head, facilitating that the optical members 120 mounted on it can further approach the scalp.

[0114] In some embodiments, the expandable element 130 has an expandable body 134 and an arcuate portion 135 disposed on the distal side of the expandable body 134.

[0115] Specifically, the curved portion 135 is located at the end, which will not cause the user to feel stinging when it comes into contact with the user's scalp or when it is extended by the extender 130. The curved contact surface of the curved portion 135 can further improve comfort.

[0116] In some embodiments, the arcuate portion 135 is made of a flexible material, and the flexibility of the material of the arcuate portion 135 is greater than that of the material of the extension body 134. The arcuate portion 135 is made of a flexible material so that when the arcuate portion 135 contacts the user's scalp and when the extension member 130 is extended, it will not cause excessive pressure on the user's scalp and cause pressure pain.

[0117] In some embodiments, the aforementioned extension body 134 may be made entirely of a flexible material or a rigid material, or a mixture of flexible and rigid materials. Its flexibility should be less than that of the first arc-shaped portion 135, allowing the extendable member 130 to unfold smoothly under the force of the surrounding environment, preventing the extension body 134 from bending and affecting the hair-flipping effect. Specifically, the flexibility of the portion of the extension body 134 near the user's scalp may be greater than that of the portion away from the user's scalp. This ensures comfort when the extension body 134 contacts the user's scalp, while also guaranteeing smooth relative unfolding of the extension body 134 during the unfolding process, preventing any impact on the hair-flipping effect.

[0118] In some embodiments, the cross-sectional area of ​​the expandable member 130 gradually decreases from its proximal side to its distal side, so that the distal end of the expandable member 130 can be smoothly inserted into the hair and rest against the user's scalp.

[0119] Specifically, the aforementioned expandable member 130 can be comb-shaped, rectangular plate-shaped, or triangular plate-shaped, or other shapes, so that the cross-sectional area of ​​the expandable member 130 gradually decreases from the proximal side to the distal side, so that the expandable member 130 can be stably pivotally connected to the bearing member 110, while also facilitating the insertion of the user's hair into the distal end of the expandable member 130.

[0120] In some embodiments, the expandable element 130 is made of a transparent material that allows light to pass through, so as to prevent blocking the light emitted or received by the optical component 120.

[0121] In some embodiments, such as Figure 1 and Figure 2 As shown, the distal end of the expandable member 130 is tapered inward to form a stepped portion 138.

[0122] Specifically, in combination Figure 1 and Figure 2The aforementioned stepped portion 138 is located on opposite sides of the arc-shaped portion 135. When the device equipped with the head optical application device 100 is worn, the arc-shaped portion 135 rests against the user's scalp. The distal side of the stepped portion 138 has a gap between itself and the user's scalp for accommodating hair, so that the parted hair can be pressed tightly during the unfolding of each expandable member 130, achieving a better hair parting effect.

[0123] It should be noted that the distal end of the expandable member 130 in each embodiment of this disclosure can be retracted inward to form a stepped portion 138, and is not limited to the technical solution of Embodiment 1. Figure 1 and Figure 2 The step portion 138 shown is for illustrative purposes only.

[0124] This disclosure presents various structural forms of transcranial photomodulation devices 200. It should be noted that the multiple optical components 120 included in the transcranial photomodulation devices 200 described below can be positioned corresponding to various regions of the brain, such as the left and right temporal regions, the top of the head, and the left and right occipital regions. Furthermore, each of these optical components 120 can emit transcranial light, which is light capable of penetrating the skull. Further details regarding this are omitted here.

[0125] According to some embodiments of this disclosure, a transcranial photomodulation device 200 is also provided, such as... Figure 14 As shown, the transcranial optical modulation device 200 includes a plurality of the aforementioned head optical application devices 100, and a housing 210 for mounting the plurality of head optical application devices 100.

[0126] In some embodiments, a plurality of elastic elements (not shown in the figure), such as springs, may be provided between the housing 210 and the head optical application device 100, and / or an elastic layer, such as a soft rubber layer, may be provided on the side of the head optical application device 100 near the user's scalp, so that when the user wears the transcranial light modulation device 200, the head optical application device 100 can adapt to the head shape of different users under the action of the elastic elements and / or the elastic layer.

[0127] The transcranial light modulation device 200 using the aforementioned head optical application device 100 enables the distal ends of each expandable member 130 to be inserted into the user's hair in a converged state, and after insertion, the distal ends of the expandable members 130 can be deployed to push aside the hair blocking the light, thus improving the problem of low light propagation rate caused by hair blocking the light and enabling the transcranial light modulation device 200 to achieve better usage effect.

[0128] In some embodiments, the housing 210 is provided with a movable member that can move distally, and the head optical application device 100 is correspondingly mounted on the movable member so that the head optical application device 100 is attached to the scalp.

[0129] Specifically, the aforementioned movable component can move towards the scalp under the action of the operator's pushing force, and after moving to a preset distance from the scalp, the head optical application device 100 mounted on the movable component can move further closer to the scalp. Through the squeezing between the movable component and the scalp, the distal ends of each expandable member 130 of the head optical application device 100 move away from each other, so as to convert to an unfolded state and push aside the obstructing hair.

[0130] According to some embodiments of this disclosure, a transcranial photomodulation device 200 is also provided, such as... Figure 15 As shown, the transcranial optical modulation device 200 includes a plurality of the aforementioned head optical application devices 100, and an elastic cross-linked network 220 for mounting the plurality of head optical application devices 100.

[0131] The design of the aforementioned elastic cross-linked mesh 220 allows it to adapt to different head shapes when worn. The elasticity of the elastic cross-linked mesh 220 enables the head optical application device 100 to fit snugly against the scalp. Even with various head shapes, the tension applied at any corresponding position on the elastic cross-linked mesh 220 can be transmitted and extended to other positions on the elastic cross-linked mesh 220 through its cross-linked topology. This allows the elastic cross-linked mesh 220 to adhere tightly to the scalp of any head shape, facilitating the subsequent unfolding of the expandable component 130 to part the hair. Furthermore, the head optical application device 100 has a certain degree of freedom in its assembly on the elastic cross-linked mesh 220, allowing for adaptive adjustments based on the user's head shape while maintaining a close fit to the scalp.

[0132] In some embodiments, the aforementioned elastic cross-linked network 220 may include a plurality of cross-connected elastic bands forming a receiving cavity around the user's head. For example, combined with Figure 15 The aforementioned elastic crosslinking network 220 may include an annular body and a strip connecting opposite sides of the annular body. The strip is positioned corresponding to the top of the user's head, and the annular body is positioned around the user's head. Multiple head optical application devices 100 may be provided on the strip and the annular body. The above description is merely an example illustrating the specific structure of the elastic crosslinking network 220, and this disclosure is not limited thereto.

[0133] For example, the above-mentioned elastic cross-linked network 220 can be integrally formed or it can be formed by connecting multiple elastic bands, and this disclosure does not specifically limit it.

[0134] According to some embodiments of this disclosure, a transcranial photomodulation device 200 is also provided, such as... Figure 16 and Figure 17As shown, the transcranial optical modulation device 200 includes a plurality of the aforementioned head optical application devices 100, and also includes an elastic crosslinking network 220 and a housing 210 for mounting the elastic crosslinking network 220, with the plurality of head optical application devices 100 arranged on the elastic crosslinking network 220.

[0135] The aforementioned housing 210 can be made of a relatively rigid material to maintain its shape, making it easy for users to wear the transcranial light modulation device 200. Simultaneously, multiple head optical application devices 100 are arranged on the elastic cross-linking network 220, allowing the head optical application devices 100 to firmly press against the scalp under the action of the elastic cross-linking network 220. This facilitates the subsequent unfolding of the expandable component 130 to part the hair, increasing the light irradiation rate on the target area of ​​the scalp. Furthermore, the elastic cross-linking network 220 can adapt to different user head shapes when worn. Through this structure, the transcranial light modulation device 200 possesses the advantages of convenient wear, good light irradiation effect, and adaptability to different user head shapes.

[0136] In some embodiments, the housing 210 is provided with a plurality of mounting members (not shown in the figure) for mounting the elastic crosslinking network 220. The mounting members have a flange at the end in a first direction toward the scalp and an annular recess of a predetermined length on the second direction side of the flange away from the scalp, so that the elastic crosslinking network 220 can be circumferentially fitted onto the annular recess and can provide expansion allowance for the fitted elastic crosslinking network 220.

[0137] In some embodiments, the elastic cross-linked network 220 may include a plurality of sheet-like elastic bands, which are sleeved on the mounting member and embedded in the annular recess. The thickness direction of the elastic cross-linked network 220 can be understood as the direction toward the scalp. Through the gap fit between the annular recess and the elastic cross-linked network 220, the elastic cross-linked network 220 can provide more expansion margin when the user's head shape expands, thereby increasing the deformation space of the elastic cross-linked network 220.

[0138] The above description is intended to be illustrative and not restrictive. For example, the above examples (or one or more thereof) can be used in combination with each other. Other embodiments may be used by those skilled in the art upon reading the above description. Furthermore, in the above detailed description, various features may be grouped together to simplify the disclosure. This should not be construed as an intention that a feature of the disclosure that is not claimed is necessary for any claim. Rather, the subject matter of this disclosure may be less than all the features of a particular disclosed embodiment.
