Description

Technical Field

[0001] The utility model belongs to the technical field of phototherapy, and in particular relates to a phototherapy device used in conjunction with nuclear magnetic resonance equipment, and a system compatible with nuclear magnetic resonance detection and phototherapy. Background Art

[0002] Phototherapy is a method of treating diseases using light of a specific wavelength. It has been widely used in neuroscience and medical research in recent years. In the prior art, when using transcranial phototherapy equipment, light with a certain wavelength is used to penetrate the human skull and stimulate cells to produce beneficial effects on cells, thereby achieving the purpose of treating brain diseases. For example, studies have shown that near-infrared light with a wavelength of 810nm can be used to treat Alzheimer's disease. In order to judge the effect of phototherapy, usually after the patient's treatment cycle is over, near-infrared brain function imaging, electroencephalogram or functional magnetic resonance imaging and other detection methods are used to detect the patient's brain function status. It is impossible to detect the patient's brain function status at the same time as phototherapy, and the brain function status can only be detected after the patient's treatment cycle is over. If the patient's brain function status cannot be obtained in time, the adjustment of phototherapy parameters and the position of phototherapy will be blind, resulting in poor effect of phototherapy.

[0030] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0031] like Figure 1 As shown, the embodiment of the utility model provides a phototherapy device used in conjunction with a nuclear magnetic device, including a light output structure and an adjustment device 1 for carrying the light output structure, the adjustment device 1 is used to adjust the light emitting direction and / or light emitting position of the light output structure;

[0032] The nuclear magnetic resonance equipment includes a fixing element 2 for fixing the position of the user's head. The fixing element 2 has a cavity for accommodating the user's head and is provided with a light-transmitting hole 20 connected to the cavity. The light output structure irradiates therapeutic light to the head through the light-transmitting hole 20 to treat brain-related diseases.

[0033] The nuclear magnetic resonance device is used to perform nuclear magnetic resonance detection on the user. The fixing element 2 can be a nuclear magnetic resonance coil or a structure provided with a nuclear magnetic resonance coil, so after the user's head is inserted into the fixing element 2, a nuclear magnetic resonance detection can be performed on the user's head. The light-transmitting hole 20 of the fixing element 2 can be set at the top or side of the fixing element 2 according to the actual treatment target, and this application does not make specific limitations on this.

[0034] The light output structure may include at least optical fiber 10, LED light-emitting panels and other components capable of transmitting near-infrared light. The adjustment device 1 may be disposed on the fixed element 2 or on the nuclear magnetic resonance device outside the fixed element 2, and is used to support the light output structure and adjust the light emission direction and / or light emission position of the light output structure, so that the light output structure irradiates the user's head with therapeutic light through the light-transmitting hole 20 of the fixed element 2. The user can perform nuclear magnetic resonance detection simultaneously during the process of light therapy, so as to adjust the light therapy plan in real time according to the results of the nuclear magnetic resonance detection. The light output structure adjusts the irradiation angle of the light and the position of the irradiated head, so that the light can accurately irradiate the preset treatment target position of the user's head (for example, the position of the user's forehead mark).

[0035] Specifically, the user in the present application refers to a patient with a brain function-related disease who uses the phototherapy device in the present application in combination with a nuclear magnetic resonance device.

[0036] The light output structure and the adjustment device 1 are both made of non-metallic materials, such as nylon, so that it can be ensured that the light output structure and the adjustment device 1 will not be disturbed or affected by the magnetic field when placed in the high magnetic field environment of the nuclear magnetic resonance room.

[0037] In some embodiments, the parameters of the light therapy include but are not limited to average power density, pulse frequency, etc. For example, the average power density of the light therapy can be set to 40-150 mW / cm 2 to ensure the effectiveness and safety of light therapy.

[0038] The term "brain" used in the present application refers to the organ remaining after removing extracerebral tissues, etc., and is primarily intended to refer to the cerebrum, but is not limited thereto and may also include the cerebrum, cerebellum, brain stem, etc.

[0039] The phototherapy device of the present application can be used in conjunction with a nuclear magnetic resonance device, which is used to perform nuclear magnetic resonance detection on a user. The fixed element of the nuclear magnetic resonance device can accommodate the user's head, and the light output structure in the phototherapy device can irradiate therapeutic light to the head through a light-transmitting hole 20 connected to the cavity of the fixed element. The adjustment device of the phototherapy device can support the light output structure and can adjust the light-emitting direction and / or light-emitting position of the light output structure, so that the user can perform the phototherapy process synchronously during the nuclear magnetic resonance detection, so as to timely adjust the light therapy parameters and the light therapy position of the phototherapy plan based on the detection results, thereby improving the phototherapy effect.

[0040] The nuclear magnetic resonance equipment is used to perform nuclear magnetic resonance detection on the user. Through the fixed element 2, the nuclear magnetic resonance detection can be performed on the user's head. The adjustment device 1 can support the light output structure to irradiate therapeutic light to the head through the light-transmitting hole 20 of the fixed element 2, so that the user can perform light therapy simultaneously during the nuclear magnetic resonance detection, so as to timely adjust the light therapy parameters and the target position of the light therapy plan based on the detection results, thereby improving the light therapy effect.

[0041] In some embodiments, the adjustment device 1 includes a first adjustment mechanism connected to the light output structure to drive the light output structure to move in a vertical direction relative to the fixing element 2, thereby adjusting the light emitting position of the light output structure.

[0042] The first adjustment mechanism can adjust the light-emitting position of the light output structure in the vertical direction, so as to adjust the irradiation position of the light emitted by the light output structure on the user's head.

[0043] In some embodiments, the first adjustment mechanism includes a lifting track 4 and a lifting rod 3 . The lifting rod 3 is slidably disposed on the lifting track 4 , and the light output structure is mounted on the lifting rod 3 .

[0044] By controlling the sliding position of the lifting rod 3, the light output structure can move within the range of the lifting track 4 to adjust the light emitting position of the light output structure in the vertical direction. Specifically, the first adjustment mechanism includes two lifting tracks 4, and the two ends of the lifting rod 3 are respectively connected to different lifting tracks 4. The light output structure is installed on the lifting rod 3, so that when the lifting rod 3 moves in the lifting track 4, it can drive the light output structure to move vertically relative to the fixed element 2. Optionally, the lifting track can be set on the fixed element 2 or on the nuclear magnetic device outside the fixed element 2 (for example, on the nuclear magnetic bed 19).

[0045] like Figure 1 As shown, a fixing frame 21 can be provided on the fixing element 2, and a lifting track is provided on the fixing frame 21. Figure 2As shown, a base 11 is arranged on the nuclear magnetic bed 19, and a vertically arranged support column 12 is arranged on the base 11, and a lifting track 4 (not shown in the figure) is arranged on the support column 12. The lifting track 4 can be arranged along the extension direction of the support column, for example, a strip opening is opened on the support column to form the lifting track 4. Among them, the bottom of the base 11 can be made of damping material, so that the base 11 can be firmly adsorbed on the nuclear magnetic bed 19 and effectively reduce accidental displacement under high-intensity magnetic fields. The support column 12 is used to support the lifting rod 3, which can ensure the stability of the vertical movement of the lifting rod 3.

[0046] In some embodiments, the adjustment device 1 further includes a second adjustment mechanism, the second adjustment mechanism includes a first slide rail and a first slider disposed on the first slide rail, the first slider is slidably connected to the first slide rail, the first slide rail is arranged in a direction perpendicular to the lifting rod 3, and the bottom of the lifting rail 4 is fixedly connected to the first slider, so that the lifting rail 4 can move along the first slide rail. The second adjustment mechanism can be disposed on the fixed element 2 or on the nuclear magnetic device outside the fixed element 2 (for example, on the nuclear magnetic bed 19), so that the first adjustment mechanism as a whole can be translated in a direction perpendicular to the lifting rod 3 (i.e., in the horizontal direction) to further adjust the irradiation position and direction of the light of the light output structure.

[0047] In some embodiments, the lifting track 4 includes a rack 15 and a gear 14, and the lifting rod 3 is connected to the gear 14. The lifting rod 3 can be inserted into the gear 14, and a thrust ring 13 can be provided at the end of the lifting rod 3. The lifting rod 3 can move vertically and can stay at any vertical position.

[0048] In some embodiments, the lifting track 4 can also include a second slide rail and a second slider. The base 11 is sleeved on the second slide rail and connected to the second slider, thereby driving the lifting rod 3 on the lifting track 4 to move in a direction perpendicular to the lifting rod 3 (i.e., horizontal direction).

[0049] In some embodiments, the adjustment device 1 includes an angle adjustment mechanism, which is connected to the light output structure so that the light output structure can rotate relative to the fixing element 2, thereby adjusting the light emission direction of the light output structure. By adjusting the light emission direction, it is helpful to adjust the coverage position of the light and improve the irradiation efficiency.

[0050] like Figure 3 As shown, in the third embodiment, the angle adjustment mechanism includes a sleeve 5, which is sleeved on the lifting rod 3, and the sleeve 5 can rotate relative to the lifting rod 3. It is convenient to adjust the angle of the light output structure. In addition, the sleeve 5 can also move along the extension direction of the lifting rod 3, and can stay at any position to change the light irradiation position along the extension direction of the lifting rod 3.

[0051] In some embodiments, the angle adjustment mechanism includes a fiber interface board 6, which is disposed above the fixed element 2 and rotatably connected to the lifting rod 3, and the light output structure is mounted on the fiber interface board 6. Taking the light output structure including the optical fiber 10 as an example, a probe hole is provided on the optical interface board, and the optical fiber 10 is connected to the probe hole. The number of probe holes can be set to multiple, and the irradiation position of the light can be adjusted by adjusting the position of the probe hole connected to the optical fiber 10, and it is also convenient to accommodate different numbers of optical fibers 10, which has flexibility and adaptability. The optical fiber interface board 6 can be made of transparent acrylic material. The scattering loss of the optical fiber interface board 6 made of acrylic material is very small, or even does not exist. The transparent optical fiber interface board 6 can be used to observe the irradiation position and angle when the user is irradiated, so as to ensure that the light power density of the light received by different users is consistent, and the error in the experimental results caused by the different light power densities received by different users can be effectively eliminated. The optical fiber interface board 6 and the lifting rod 3 can be connected by a rotating structure, such as a sleeve 5. The optical interface board and the sleeve 5 are fixedly connected or integrally arranged, so that the optical fiber interface board 6 can drive the light output structure to move or rotate. The sleeve 5 can be made of a material with greater damping so that the sleeve 5 can rotate relative to the lifting rod 3 and can stay at any position to adjust the angle of the light in the circular direction around the lifting rod 3 when the user performs light therapy. It can also maintain the stability of the optical fiber interface board 6 and improve the transmission quality of the optical fiber 10.

[0052] like Figure 4 and Figure 5 As shown, in some embodiments, the angle adjustment mechanism includes a direction adjustment element and a clamping member, the direction adjustment element includes an optical light guide channel 7 or a universal adjuster 16, the clamping member includes a fixing portion 8 and at least two clamping claws 9, and the fixing portion 8 is arranged on the lifting rod 3, the fixing portion 8 is fixedly connected to the at least two clamping claws 9, and the direction adjustment element is connected to the at least two clamping claws 9, so that the direction adjustment element rotates to adjust the light output direction of the light output structure. The fixing portion 8 can move vertically with the lifting rod 3, and can translate along the extension direction of the lifting rod 3. The optical light guide channel 7 can be a light pipe, and the input end of the optical light guide channel 7 is used to receive an optical signal, and the optical signal can be input into the optical light guide channel 7 through an optical fiber 10. The output end of the optical light guide channel 7 is used to output an optical signal, and the optical signal will be transmitted to the target irradiation position. The optical light guide channel 7 contains an optical path inside for transmitting the optical signal therein. The optical path can guide and transmit the optical signal through total reflection, refraction or waveguide effect. The optical fiber 10 is sleeved and connected to the input end of the optical light-guiding channel 7 , and extends into the inner side of the cavity through the output end of the optical light-guiding channel 7 .

[0053] in addition, Figure 4 A lifting track 4 (not shown in the figure) can also be arranged on the support column 12.

[0054] The universal adjuster 16 includes an input shaft, a universal ring and an output shaft. The input shaft of the universal adjuster 16 is fixed by a clamp 9. The optical fiber 10 is connected to the output end of the universal adjuster 16 and extends into the inner side of the cavity to irradiate the therapeutic light to the inner side of the cavity. The irradiation direction of the optical fiber 10 can be changed by manually adjusting the universal adjuster 16.

[0055] like Figure 6 As shown, in some embodiments, the light output structure includes a beam expander 17, which expands the therapeutic light so that the diameter of the light spot formed by the therapeutic light in the treatment target area on the head reaches a preset value. The end of the optical fiber 10 is detachably connected to the beam expander, which can enlarge the diameter of the light beam, thereby increasing the diameter of the scattered light spot, improving the uniformity of light therapy, reducing energy density, adapting to different treatment needs, and protecting the safety of users and operators.

[0056] like Figure 7 As shown, in some embodiments, the phototherapy device used in conjunction with the nuclear magnetic resonance equipment further includes a laser emitter 18. The laser emitter 18 and the adjustment device 1 can be located in different spaces, for example, the adjustment device 1 can be located in the nuclear magnetic resonance room, and the laser emitter 18 can be located in the operating room outside the nuclear magnetic resonance room, ensuring that there are no non-metallic devices in the nuclear magnetic resonance room, and the laser emitter 18 is connected to the adjustment device 1 through the light output structure. Taking the optical output structure as an optical fiber 10 as an example, the laser emitter 18 is connected to the optical fiber 10 in a detachable manner, and one end of the interface connection between the optical fiber 10 and the laser emitter 18 can be a 905 interface, which can ensure excellent wear resistance and high temperature resistance, and ensure long-term stable operation under high output power tasks.

[0057] The laser emitter 18 is a light source that generates a high-intensity, monochromatic laser beam by activating a laser medium. In the operating room, an intelligent software control system is used to achieve precise regulation of the output power of the laser emitter 18, as well as rapid switching between working modes such as continuous wave (CW), pulse wave (TTL) and analog wave (Analog). Such a design can meet the diversity of different patients and treatment needs as well as the personalized needs of different light therapy parameters. The light therapy parameters can be adjusted instantly according to real-time magnetic resonance imaging data to ensure the accuracy and therapeutic effect of light therapy. In terms of output wavelength, a laser with a central wavelength of 808±5nm is used. Preferably, the laser emitter 18 emits a laser with a central wavelength of 808nm to the patient's head, which can achieve effective light therapy effects from the surface of the skin to deep tissues.
