Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a photostimulation component, photostimulation device, and photostimulation system for treating brain function-related diseases. Background Technology

[0002] Epidemiological surveys show that the incidence of brain function-related diseases in modern society is on the rise. Among them, Alzheimer's disease (AD), mild cognitive impairment (MCI), depression, autism, bipolar disorder, manic-depressive disorder, and brain injury are some of the more common brain function-related diseases.

[0003] Currently, many brain imaging technologies can be used to study these brain function-related diseases, including magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and PET imaging. Brain modulation technologies, such as photostimulation, can directly intervene in neuronal activity to regulate the brain. When combined with brain modulation technologies, brain imaging can effectively reflect changes in brain function during or before and after treatment. However, there are often scenarios where photostimulation devices are inconvenient to integrate into brain imaging equipment. For example, the device may be too large to fit inside, or some components may interfere with the imaging, making it impossible to place the entire device within the imaging apparatus. This necessitates the use of technical means to transmit the light emitted from the light source to the imaging device, such as using long optical fibers. Particularly when applied in magnetic field environments, the integrated electronic circuits in the light output components of existing photostimulation technologies are often unable to withstand strong magnetic field interference. Therefore, there are certain technical obstacles to combining photostimulation devices with brain imaging or brain therapy technologies (such as transcranial magnetic stimulation) in magnetic field environments. Existing photostimulation devices used in such scenarios mostly employ point light sources at the ends of optical fibers during treatment. This results in problems such as small irradiation area and uneven light power in the treatment area, leading to poor treatment effects. It is difficult to meet the requirement of emitting a light spot of a certain area with relatively uniform light power at close range to the patient's head. Utility Model Content

[0004] This application aims to provide a photostimulation component, photostimulation device, and photostimulation system for treating brain function-related diseases, in order to solve the problems of small light source irradiation area, uneven light power in the treatment area, and poor treatment effect in some existing photostimulation devices used in special scenarios.

[0005] According to a first aspect of this application, a photostimulation component for treating brain function-related diseases is provided.

[0006] In some embodiments, the receiving cavity is provided with a mounting groove, which is distributed in a spiral shape in the receiving cavity, and the optical transmission element is disposed in the mounting groove.

[0007] In some embodiments, the radius of curvature of the mounting groove is not less than 2 mm.

[0008] In some embodiments, a reflective layer is provided on the side of the carrier away from the head.

[0009] In some embodiments, the carrier includes a body and a cover, the cover being engaged with the body to form the receiving cavity.

[0010] In some embodiments, the receiving cavity is provided with a mounting groove, the carrier has a slot, the slot is connected to the mounting groove, and one end of the optical transmission element for emitting the near-infrared light enters the mounting groove through the slot.

[0011] In some embodiments, the photostimulation assembly further includes a headband and fasteners, wherein the carrier is fixedly assembled to the headband by the fasteners.

[0012] In some embodiments, the headband is made of silicone material and has a through hole in the middle for mounting the fastener.

[0013] According to a second aspect of this application, a photostimulation device for treating brain function-related diseases is provided, the photostimulation device comprising: a light source and a photostimulation component as described in any of the preceding claims, wherein the light source emits near-infrared light for treating brain function-related diseases, and one end of the light transmission component is used to receive the near-infrared light and circumferentially emit the near-infrared light.

[0014] In some embodiments, the photostimulation device further includes a light-guiding optical fiber, one end of which is coupled to the light source and the other end of which is coupled to the light transmission element, wherein the core diameter of the light-guiding optical fiber is smaller than the core diameter of the light transmission element.

[0015] According to a third aspect of this application, a photostimulation system for treating brain function-related diseases is provided, the photostimulation system comprising: a photostimulation device as described in any of the preceding claims and a support for supporting the photostimulation device.

[0016] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: This utility model uses a light transmission device that can emit near-infrared light circumferentially, and arranges the light transmission device in a spiral shape in the receiving cavity of the carrier, so that the near-infrared light can irradiate the patient's head with a larger irradiation area and relatively uniformly. Furthermore, a light-diffusing layer is set on one side of the light-transmitting part of the carrier, which allows the near-infrared light to irradiate the patient's head more uniformly. While satisfying the requirement of emitting a light spot of a certain area at close range to the treatment area of ​​the head, it also ensures a relatively uniform distribution of light power, greatly improving the treatment effect for patients with brain function-related diseases in some special scenarios. At the same time, since the photostimulation component provided in this application only has a light transmission device and a carrier in the treatment area of ​​the patient's head, there is no interference from strong magnetic fields. Therefore, it can be used in conjunction with technologies such as magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) to achieve real-time monitoring of changes in the patient's brain function status while using photostimulation to treat brain function-related diseases. This can be used to evaluate the therapeutic effect of photostimulation and guide photostimulation treatment plans.

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

[0031] 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.

[0032] This utility model provides a photostimulation component for treating brain function-related diseases. Existing research shows that the incidence of brain function-related diseases in modern society is increasing year by year. Among them, Alzheimer's disease (AD), mild cognitive impairment (MCI), depression, autism, bipolar disorder, manic-depressive disorder, and brain injury are common brain function-related diseases. The photostimulation component provided in this application can be used to treat, but is not limited to, the above-mentioned brain function-related diseases.

[0033] like Figure 1As shown, this utility model embodiment provides a photostimulation component 100 for treating brain function-related diseases. The photostimulation component 100 includes: a light transmission element 110, one end of which is used to receive near-infrared light for treating brain function-related diseases and emits the near-infrared light circumferentially. Specifically, the light transmission element 110 only needs to be able to emit light throughout the optical fiber after receiving the corresponding near-infrared light at one end during use, and the light is scattered relatively uniformly along the length of the optical fiber. It can be linearly emitting, for example, it can be a side-emitting optical fiber, or other optical fibers. This application does not specifically limit this. A carrier element 120 is formed with a receiving cavity 121. The other end of the light transmission element 110 extends into the receiving cavity 121 and is arranged in a spiral shape in the receiving cavity 121. In this way, the light transmission element can be relatively uniformly distributed in the receiving cavity, and the near-infrared light can be uniformly scattered in the receiving cavity. A light-transmitting part 122 is provided on the side of the carrier near the head, and a light-uniforming layer 1221 is provided corresponding to the light-transmitting part 122 so that near-infrared light is irradiated onto the head more evenly.

[0034] The light-transmitting part 122 can be made of transparent or frosted material. In some embodiments, the light-diffusing layer 1221 can also be a light-diffusing coating applied to the outer peripheral surface of the light-transmitting part 122. For example, the light-diffusing layer 1221 can also be a light-diffusing film attached to the outer peripheral surface of the light-transmitting part 122. The light-diffusing layer 1221 is set on the side of the light-transmitting part 122 near the head. The light-transmitting part itself is made of a light-diffusing material, such as frosted material. There are various ways to set the light-diffusing layer 1221. This application does not make specific limitations on the correspondence between the light-diffusing layer and the light-transmitting part 122, or the setting method of the light-diffusing layer 1221, as long as the light-diffusing layer 1221 can achieve more uniform irradiation of the near-infrared light emitted by the light transmission element 110 in the carrier 120 onto the head.

[0035] In some embodiments, the side of the support 120 closest to the head is curved, which can better fit the patient's head, making it easier for the patient to use and improving wearing comfort.

[0036] The photostimulation component 100 of this embodiment employs a light transmission element 110 capable of circumferentially emitting near-infrared light, and the light transmission element 110 is spirally arranged in the receiving cavity 121 of the carrier 120. This allows the near-infrared light to irradiate the patient's head with a larger irradiation area and relatively uniform illumination. Furthermore, a light-diffusing layer 1221 is provided on one side of the light-transmitting portion 122 of the carrier 120, which allows the near-infrared light to irradiate the patient's head more uniformly. The area of ​​the emitting surface of the carrier is much larger than that of the point light source. While satisfying the requirement of emitting a light spot of a certain area at close range to the treatment area of ​​the head, it also ensures a relatively uniform distribution of light power, which greatly improves the treatment effect for patients with brain function-related diseases in some special scenarios.

[0037] Furthermore, when the photostimulation component 100 of this utility model embodiment is used in conjunction with technologies such as magnetoencephalography (MEG) or functional magnetic resonance imaging (fMRI), since the photostimulation component 100 only has a light transmission component and a carrier component in the treatment area of ​​the patient's head, there is no interference from a strong magnetic field. Therefore, it is possible to combine brain imaging technology and brain modulation technology, and realize timely monitoring of changes in the patient's brain function status while using photostimulation to treat brain function-related diseases. It can be used to evaluate the therapeutic effect of photostimulation and guide photostimulation treatment plans.

[0038] In some embodiments, the photostimulation component 100 of this utility model can also be used in conjunction with other treatment devices, such as transcranial magnetic stimulation (TMS). When used in conjunction with TMS, the photostimulation component 100 of this utility model is not affected by magnetic field interference. While emitting a light spot of a certain area at close range to the treatment area of ​​the head, it also ensures a relatively uniform distribution of light power. Therefore, it can not only achieve synergistic treatment of photostimulation and magnetic stimulation, but also achieve better treatment results.

[0039] In some embodiments, such as Figure 2 As shown, the carrier 120 includes a body 123 and a cover 124, with the cover 124 engaging with the body 123 to form a receiving cavity 121. The carrier 120 is a separate unit, which facilitates the removal or placement of the optical transmission element 110 and minimizes the risk of damage to the optical transmission element 110.

[0040] In some embodiments, a mounting groove is provided in the receiving cavity 121, and the mounting groove is spirally distributed in the receiving cavity 121. The light transmission element 110 is disposed in the mounting groove. The mounting groove divides the receiving cavity 121 into a relatively uniform space. The mounting groove limits the position of the light transmission element 110, ensuring the stability of the light transmission element 110 and the relative uniformity of near-infrared light emission in the circumferential direction during the treatment of brain function-related diseases. In some embodiments, such as... Figure 2 As shown, spirally distributed partitions 1211 can be provided in the receiving cavity 121, and the space between adjacent partitions 1211 in the receiving cavity 121 forms a mounting groove. Preferably, the spacing between the partitions is uniform, further improving the relative uniformity of circumferential near-infrared light emission. It is understood that an integrated mounting groove can also be placed directly in the receiving cavity 121, with the mounting groove spirally distributed in the receiving cavity 121, for placing the optical transmission element 110. In some embodiments, the mounting groove can be formed on the body 123 or on the cover 124. This application does not specifically limit the formation method or location of the mounting groove, as long as it is distributed in the receiving cavity 121 and can limit the position of the optical transmission element 110.

[0041] In some embodiments, the relative uniformity of near-infrared light can be adjusted by adjusting the spacing between the separators.

[0042] In some embodiments, the radius of curvature of the mounting groove is not less than 2 mm, and preferably, the radius of curvature of the mounting groove is not greater than 10 mm. This arrangement ensures that the spiral arrangement of the light transmission element 110 on the carrier 120 is neither too dense nor too sparse, while also ensuring that the light transmission element 110 meets the minimum bending radius, reducing damage to the light transmission element 110. While satisfying the requirement of emitting a certain area of ​​light spot at close range to the head treatment area, it also ensures the uniform distribution of light power, so that the light power irradiated to the patient's head treatment area is neither too large nor too small, improving the patient's treatment compliance and greatly improving the treatment effect for patients with brain function-related diseases.

[0043] In some embodiments, a reflective layer is provided on the side of the carrier away from the head. For example... Figure 2 As shown, for ease of understanding, the carrier 120 includes a body 123 and a cover 124, with the body 123 located on the side closer to the patient's head, and the cover 124 located on the side farther from the patient's head. A light-transmitting portion 122 is provided on the side of the carrier 120 closest to the head, i.e., a light-transmitting portion 122 is provided on the body 123. A light-diffusing layer is correspondingly provided on the light-transmitting portion 122, as described previously and will not be repeated here. A reflective layer 1241 is provided on the side of the carrier 120 farther from the head, i.e., a reflective layer 1241 is provided on the cover 124. For example, the reflective layer can be a reflective coating applied to the cover 124, or a reflective film attached to the cover 124, or a reflective cylindrical structure made of reflective material and fitted onto the cover 124, etc. The location and method of the reflective layer can be varied. This application does not impose specific limitations on the location or method of setting the reflective layer 1241, as long as the reflective layer can reflect the near-infrared light emitted by the light transmission member 11 in the carrier member 120 to the light-transmitting part 122 and be emitted by the light-uniforming layer.

[0044] In some embodiments, in addition to the reflective layer 1241 being provided on the side of the carrier 120 away from the head, a reflective layer 1241 may also be provided on the outer peripheral surface of the carrier 120. This allows the light emitted by the light transmission member 110 to the side to be reflected and emitted through the light homogenizing layer to illuminate the treatment area of ​​the patient's head, thus avoiding energy waste. Exemplarily, besides the carrier 120 being a separate unit as described above, the carrier 120 may also be a single unit, with the reflective layer and the light homogenizing layer located on opposite sides of the carrier to achieve the effects of reflected light and light homogenization, respectively. The construction mechanism is the same as described above and will not be repeated here.

[0045] In some embodiments, the carrier has a slot 125 that communicates with the receiving cavity 121, and one end of the optical transmission member 11 that emits near-infrared light enters the receiving cavity 121 through the slot 125. Further, when a mounting slot is provided in the receiving cavity 121, the slot 125 communicates with the mounting slot to allow the optical transmission member 11 to enter the mounting slot through the slot 125.

[0046] In some embodiments, such as Figure 3 As shown, the photostimulation assembly 100 also includes a fastener 130 and a headband 140, wherein the carrier 120 is fixedly assembled with the headband 140 by the fastener 130. The fastener 130 has a receiving hole 131 in the middle for accommodating the carrier 120. After the carrier 120 is inserted into the receiving hole 131, it is interference-fitted and / or glued to the fastener 130. The fastener 130 has a first opening 132. When the carrier 120 is fixed with the fastener 130, the first opening 132 on the fastener 130 is used to allow the slot 125 of the carrier 120 to be placed.

[0047] In some embodiments, the headband 140 is made of silicone material, and a through hole 141 is provided in the middle of the headband 140. The through hole 141 is correspondingly provided with a fastener 130 for mounting the fastener 130. The headband 140 is made of silicone material, which easily conforms to the patient's head, improving the patient's comfort during wear. Figure 4 As shown, the headband 140 has a clamping mechanism 143 at both ends. The structure of the clamping mechanism 143 can be arbitrary, including but not limited to straps, Velcro, tape, hooks and / or clips. During wear, the headband 140 can be tightly clamped to the patient's head using the clamping mechanism 143.

[0048] This utility model embodiment also provides a photostimulation device 10 for treating brain function-related diseases, such as... Figure 5As shown, the photostimulation device 10 includes a light source 200 and a photostimulation component 100 as described in any of the preceding embodiments. The light source 200 emits near-infrared light for treating brain function-related diseases, and one end of a light transmission element receives the near-infrared light emitted by the light source 200 and emits the near-infrared light circumferentially. In some embodiments, the light source 200 can be a laser, and there can be more than one laser; the light transmission elements are configured in a one-to-one correspondence with the lasers. In scenarios where only photostimulation devices are used, the light source provides near-infrared light, and the light transmission device transmits the light and emits the received near-infrared light circumferentially. Thus, by employing a light transmission device that can emit near-infrared light circumferentially and arranging it in a spiral shape within the receiving cavity of the carrier, the near-infrared light can irradiate the patient's head with a larger irradiation area and relatively uniformity. Furthermore, by setting a light-diffusing layer on one side of the light-transmitting part of the carrier, the near-infrared light can irradiate the patient's head more uniformly. This not only satisfies the requirement of emitting a light spot of a certain area at close range to the treatment area of ​​the head but also ensures a relatively uniform distribution of light power, greatly improving the treatment effect for patients with brain function-related diseases in some special scenarios (such as scenarios where it is used in conjunction with MRI or MRI devices).

[0049] In some embodiments, such as Figure 5 As shown, the photostimulation device 10 also includes a light-guiding fiber 300. One end of the light-guiding fiber 300 is coupled to the light source unit 200, and the other end is coupled to the optical transmission element. The core diameter of the light-guiding fiber 300 is smaller than the core diameter of the optical transmission element. In scenarios involving the use of photostimulation devices in conjunction with technologies such as magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), or magnetic stimulation therapy, the light source unit 200 cannot be too close to the patient due to magnetic field interference. Therefore, the participation of a light-guiding fiber and an optical transmission element is necessary. The light-guiding fiber is used to receive near-infrared light emitted by the light source unit 200 and transmit the received near-infrared light to the optical transmission element. For example, the light-guiding fiber is a point light source emitting fiber, and the core diameter of the light-guiding fiber is not larger than the core diameter of the optical transmission element. Preferably, the core diameter of the light-guiding fiber is smaller than the core diameter of the optical transmission element, which ensures that the fiber splicing loss is minimized. Because the optical fiber is long enough, the photostimulation device provided in this embodiment only has a light transmission component and a carrier component in the treatment area of ​​the patient's head, and there is no interference from the magnetic field. Therefore, it can be used in conjunction with technologies such as magnetoencephalography (MEG) or functional magnetic resonance imaging (fMRI) to realize timely monitoring of changes in the patient's brain function status while using photostimulation to treat brain function-related diseases. It can be used to evaluate the therapeutic effect of photostimulation and guide photostimulation treatment plans.

[0050] In some embodiments, the photostimulation device provided in this application can be used in conjunction with other treatment devices, such as transcranial magnetic stimulation (TMS). It can be unaffected by magnetic field interference and, while satisfying the requirement of emitting a light spot of a certain area at close range to the treatment area of ​​the head, also ensures a relatively uniform distribution of light power. Therefore, photostimulation and magnetic stimulation can be used in synergistic treatment to achieve better treatment results.

[0051] This invention also provides a photostimulation system for treating brain function-related diseases, such as... Figure 5 As shown, the photostimulation system 1 includes: a photostimulation device 10 as described in any of the preceding embodiments and a support 20 supporting the photostimulation device 10.

[0052] Exemplarily, the support 20 has a first supporting portion 21, which is located at the top of the support 20, and the position of the first supporting portion 21 near the center is the placement portion 211 of the photostimulation component 100. A receiving cavity 212 is provided around the outer periphery of the placement portion 211 on the first supporting portion 21. The receiving cavity 212 is used to place the light guiding fiber 300. In use, the light guiding fiber 300 is generally long, and the receiving cavity 212 facilitates its storage. It is understood that the receiving cavity 212 can be constructed as a ring. Exemplarily, the receiving cavity 212 can be constructed as multiple ring cavities. In this embodiment, the illustration shows a receiving cavity 212 with two rings: an inner ring and an outer ring. Figure 5 As shown, relative to the inner ring of the storage cavity, at least one first recess facing the center is provided on the placement part 211. This first recess facilitates the user's hand to enter and grasp the optical fiber during use. Relative to the outer ring of the storage cavity, a second recess facing the outer periphery is also provided on the first support part 21 near its outer periphery. This second recess also facilitates the user's hand to enter and grasp the optical fiber during use.

[0053] For example, the support 20 also has a second support portion 22, which is located at the lower end of the first support portion 21 and is used to place the light source portion 200. A wire-fixing portion 213 is also provided at the edge of the first support portion 21 for organizing and fixing the optical fiber 300. The wire-fixing portion 213 and the storage cavity 212 on the first support portion 21 facilitate the organization and storage of the long optical fiber 300, making it convenient for the user to access the photostimulation component.

[0054] This invention employs a light transmission component capable of circumferentially emitting near-infrared light, arranged spirally within the receiving cavity of a carrier component. This allows near-infrared light to irradiate the patient's head with a larger and more uniform irradiation area. Furthermore, a light-diffusing layer is provided on one side of the carrier component's light-transmitting portion, ensuring even more uniform irradiation of the near-infrared light onto the patient's head. This achieves both the emission of a certain area of ​​light spot at close range to the treatment area and the uniform distribution of light power, significantly improving the treatment efficacy for patients with brain function-related diseases in certain specific scenarios. Simultaneously, since the photostimulation component provided in this application only contains the light transmission component and the carrier component in the treatment area of ​​the patient's head, it is not subject to interference from strong magnetic fields. Therefore, it can be used in conjunction with technologies such as magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) to monitor changes in the patient's brain function status while using photostimulation to treat brain function-related diseases. This can be used to evaluate the therapeutic effect of photostimulation and guide photostimulation treatment plans. The support structure in the photostimulation system further facilitates the storage, organization, and use of the photostimulation device, greatly improving the user experience and providing convenience for medical personnel.

Furthermore, in the above detailed description, various features may be grouped together to simplify the invention.
