Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a near-infrared light therapy device for treating Alzheimer's disease. Background Technology

[0002] Alzheimer's disease (AD) is an insidious neurodegenerative disease and the most common cause of dementia. Its main pathological features are the formation of "senile plaques" (β-amyloid protein deposits) and "neurofibrillar tangles" (Tau protein hyperphosphorylation) in the brain. These lesions lead to significant neuronal loss and brain atrophy, particularly in the hippocampus and cortex, which are associated with memory. Near-infrared light therapy for Alzheimer's disease (AD) is a novel non-invasive neuromodulation therapy. Its core principle is to use near-infrared light of a specific wavelength (600-1100 nm) to penetrate the skull and act on brain tissue. Studies have shown that near-infrared light can be absorbed by cytochrome c oxidase in mitochondria, thereby enhancing the synthesis of ATP and improving neuronal metabolic function.

[0003] A Chinese patent application (or patent) with publication number CN105126256B discloses a near-infrared light therapy device for treating Alzheimer's disease, including a housing, a movable arm mounted on the housing, and a head-mounted mechanism mounted at one end of the movable arm. The head-mounted mechanism is movable up and down on the housing via the movable arm. The housing also has a human-machine interface. The device further includes a near-infrared light irradiation mechanism and a near-infrared light irradiation control unit mounted inside the head-mounted mechanism. The near-infrared light irradiation mechanism is foldable and retractable inside the head-mounted mechanism via connecting elements.

[0004] However, the above-mentioned device still has the following problems in its implementation: When the near-infrared light therapy device is used, light is emitted by near-infrared light-emitting diodes inside the head cover to irradiate the patient. However, the distribution distance of the near-infrared light-emitting diodes inside the head cover is fixed, and the angle and direction of irradiation on the patient's head are also fixed. It is impossible to dynamically adjust according to the individual patient's head shape and brain region structure. Although this uniform irradiation mode ensures the standardization of treatment, it will limit the optimal coverage efficiency of light on specific target brain regions (such as the hippocampus) and affect the treatment effect.

[0005] To address this issue, we offer a near-infrared light therapy device for treating Alzheimer's disease. Summary of the Invention

[0006] The purpose of this invention is to provide a near-infrared light therapy device for treating Alzheimer's disease. By cooperating with the adjustment component, the limiting component and the ventilation component, the invention solves the problem that the angle and range of irradiation therapy for patients in the prior art infrared light therapy device are fixed, and that it is impossible to perform targeted irradiation therapy.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to a near-infrared light therapy device for treating Alzheimer's disease, comprising a treatment table, a support movably connected to the top of the treatment table, a support shell at the other end of the support, and a first infrared lamp plate installed inside the support shell; an adjustment component is provided on one side of the support shell, the adjustment component including a ring movably connected inside the support shell, a second infrared lamp plate installed inside the ring, and the irradiation range of the second infrared lamp plate being adjusted by the adjustment component; a limiting component is provided on one side of the ring, the limiting component including a support frame installed on one side of the ring, a movable rod slidably connected inside the support frame, rubber pads installed at both ends of the movable rod, and a screw threadedly connected inside the movable rod, the limiting component fixing the range of the second infrared lamp plate; a ventilation component is provided on the top of the treatment table, the ventilation component including a fan installed on the top of the treatment table, a delivery pipe connected to the air outlet of the fan, a fixed pipe installed on the top of the support shell, a fixed sleeve movably connected to the surface of the fixed pipe, and an air outlet pipe connected to one side of the fixed sleeve, the ventilation component increasing the ventilation effect during treatment.

[0009] The present invention is further configured such that a support assembly is provided on one side of the bracket, the support assembly including a connecting frame provided on one side of the bracket, a rotating shaft movably connected to the inside of the bracket, a threaded rod threadedly connected to the inside of the rotating shaft, and a compression cap fixedly connected to one side of the threaded rod, thereby fixing the adjustment angle of the bracket through the support assembly.

[0010] The present invention is further configured such that the support assembly includes an extrusion disc slidably connected to the surface of the rotating shaft, a slide rod slidably connected to the inside of the connecting frame, and a friction block disposed on one side of the extrusion disc.

[0011] The present invention is further configured such that one end of the slide bar is fixedly connected to the extrusion plate, the other end of the rotating shaft is fixedly connected to the connecting frame, and the other end of the connecting frame is fixedly connected to the fixed tube.

[0012] The present invention is further configured such that an air outlet is provided inside the ring, and the other end of the air outlet pipe is connected to the air outlet.

[0013] The present invention is further configured such that the surface of the fixed tube is provided with an exhaust hole for communicating with the exhaust pipe.

[0014] The present invention is further configured such that a fixing plate is fixedly connected to one side of the support shell, and the fixing plate is arc-shaped to provide support and fixation.

[0015] The invention is further configured such that circular guide rails are fixedly connected to the top and bottom of the ring, and guide rail grooves are provided inside the support shell.

[0016] The invention is further configured such that one end of the screw is movably connected to the ring via a bearing, and the other end of the screw passes through the support frame and is fixedly connected to a knob.

[0017] The present invention is further configured such that a buckle is sleeved on the surface of the conveying pipe, and one end of the buckle is fixedly connected to the bracket.

[0018] The present invention has the following beneficial effects.

[0019] This invention achieves precise adjustment and reliable fixation of the near-infrared light irradiation angle by setting a rotatable ring and a second infrared lamp plate installed inside it, in conjunction with a limiting component consisting of a support frame, a moving rod, a rubber pad, and a screw. This allows medical staff to dynamically adjust the irradiation direction of the second infrared lamp plate according to the individual differences in the brain structure of patients, especially for precise directional irradiation of key areas such as the hippocampus. Compared with the fixed-angle irradiation method in the prior art, this device significantly improves the targeting and adaptability of treatment and effectively solves the problem of irradiation blind spots caused by differences in head shape.

[0020] This invention integrates a ventilation assembly consisting of a fan, a delivery pipe, a fixed pipe, and an outlet pipe. The ventilation airflow is delivered to the support shell area through the fixed pipe and then directionally discharged through the outlet holes inside the ring, forming an effective circulation around the patient's head. This design not only dissipates the heat generated by the infrared lamp panel during operation in a timely manner, maintaining stable operation of the equipment and extending its service life, but more importantly, it creates a comfortable treatment environment for the patient's head, avoiding discomfort caused by excessive local temperature or stuffiness, and improving the patient's comfort during longer treatment periods.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1 Please see Figures 1-8This invention relates to a near-infrared light therapy device for treating Alzheimer's disease, comprising a treatment table 1, a support 2 movably connected to the top of the treatment table 1, a support shell 3 at the other end of the support 2, and a first infrared lamp plate 4 installed inside the support shell 3; an adjustment component 5 is provided on one side of the support shell 3, the adjustment component 5 including a ring 501 movably connected inside the support shell 3, and a second infrared lamp plate 502 installed inside the ring 501, the irradiation range of the second infrared lamp plate 502 being adjusted by the adjustment component 5; a limit component 6 is provided on one side of the ring 501, the limit component 6 including a support frame 601 installed on one side of the ring 501, slidably connected to... The moving rod 602 inside the support frame 601, the rubber pads 603 installed at both ends of the moving rod 602, and the screw 604 threadedly connected inside the moving rod 602, fix the range of the second infrared lamp plate 502 through the limiting component 6; the top of the treatment table 1 is provided with a ventilation component 7, which includes a fan 701 installed on the top of the treatment table 1, a delivery pipe 702 connected to the air outlet of the fan 701, a fixed pipe 703 installed on the top of the support shell 3, a fixed sleeve 704 movably connected to the surface of the fixed pipe 703, and an air outlet pipe 705 connected to one side of the fixed sleeve 704. The ventilation component 7 increases the ventilation effect during treatment.

[0034] Specifically: The support 2 can flexibly adjust the position of the support shell 3 to adapt to patients of different heights and sitting postures, improving ease of use. Multiple sets of first infrared lamp panels 4 are installed inside the support shell 3 to ensure uniform light coverage of the patient's head. The first infrared lamp panels 4 are responsible for providing basic whole-brain irradiation functions, suitable for routine treatment scenarios. The ring 501 is movably connected inside the support shell 3. The rotation design of the ring 501 makes the angle of the second infrared lamp panel 502 adjustable, thereby achieving targeted irradiation of different brain regions. The second infrared lamp panel 502 is installed inside the ring 501. As an auxiliary light source, the second infrared lamp panel 502 can be used to enhance the light intensity of specific areas such as the hippocampus, improving the targeting and effectiveness of treatment. The support frame 601 provides a stable sliding track for the moving rod 602. The moving rod 602 achieves the pressing and releasing of the rubber pad 603 by sliding. The rubber pad 603 is made of high-friction material, which can effectively increase the friction between the rubber pad and the support shell 3, ensuring a firm fixation.

[0035] Example 2 Please see Figures 1-8Based on Embodiment 1, a support assembly 8 is provided on one side of the bracket 2. The support assembly 8 includes a connecting frame 801 provided on one side of the bracket 2, a rotating shaft 802 movably connected to the inside of the bracket 2, a threaded rod 803 threadedly connected to the inside of the rotating shaft 802, and a compression cap 804 fixedly connected to one side of the threaded rod 803. The support assembly 8 is used to fix the adjustment angle of the bracket 2. The support assembly 8 also includes a compression plate 805 slidably connected to the surface of the rotating shaft 802, a slide rod 806 slidably connected to the inside of the connecting frame 801, and a friction block provided on one side of the compression plate 805. One end of the slide rod 806 is fixedly connected to the compression plate 805, the other end of the rotating shaft 802 is fixedly connected to the connecting frame 801, the other end of the connecting frame 801 is fixedly connected to the fixed tube 703, an air vent 9 is provided inside the ring 501, the other end of the air vent 705 is connected to the air vent 9, and an exhaust hole 10 is provided on the surface of the fixed tube 703 for connecting with the air vent 705.

[0036] Specifically: the screw 604 achieves precise movement of the moving rod 602 through threaded transmission; the fan 701 serves as the air source, providing continuous airflow; the delivery pipe 702 is responsible for guiding the airflow to the support shell 3 area; the fixed pipe 703 serves as the airflow distribution channel, and its optimized internal structure ensures uniform airflow distribution; the fixed sleeve 704 can rotate along the fixed pipe 703, facilitating adjustment of the air outlet direction; the air outlet pipe 705 delivers airflow directly to the area around the patient's head, enhancing local ventilation; the rotating shaft 802 allows the bracket 2 to be flexibly adjusted within a certain angle range; the threaded rod 803 achieves axial movement through rotation, thereby pushing the compression cap 804 to press against the friction surface; and the angle is quickly fixed by tightening.

[0037] Example 3 Please see Figures 1-8 Based on Embodiments 1 and 2, a fixing plate 11 is fixedly connected to one side of the support shell 3. The fixing plate 11 is arc-shaped and serves to support and fix the ring 501. Circular guide rails 12 are fixedly connected to the top and bottom of the ring 501. A guide rail groove 13 is opened inside the support shell 3. One end of the screw 604 is movably connected to the ring 501 through a bearing. The other end of the screw 604 passes through the support frame 601 and is fixedly connected to a knob 14. A buckle 15 is sleeved on the surface of the conveying pipe 702. One end of the buckle 15 is fixedly connected to the bracket 2.

[0038] Specifically: the air outlet 9 allows airflow to pass through the inside of the ring 501, further enhancing the local heat dissipation effect. The top and bottom of the ring 501 are fixedly connected to circular guide rails 12, which allow the ring 501 to rotate smoothly inside the support shell 3, reducing friction and noise. The support shell 3 has a guide rail groove 13 inside, which cooperates with the circular guide rail 12 to ensure the guidance and stability of the ring 501 when rotating. The surface of the conveying pipe 702 is fitted with a buckle 15, which is used to fix the position of the conveying pipe 702 and prevent the conveying pipe 702 from loosening or falling off.

[0039] The working principle of this invention is as follows: Medical staff assist the patient to sit up, then move the support shell 3 so that the support shell 3 is fitted onto the patient's head position. Then, the support angle is adjusted by rotating the bracket 2 and the connecting frame 801. After adjusting to the specified angle, the compression cap 804 is manually rotated. The compression cap 804 drives the threaded rod 803 to rotate. The threaded rod 803 is connected to the rotating shaft 802 by threads. When the threaded rod 803 rotates, it can drive the compression cap 804 to push the compression plate 805. The compression plate 805 and the friction block increase the friction between the connecting frame 801 and the bracket 2, thereby fixing the support angle of the support shell 3.

[0040] Then, the first infrared lamp panel 4 is activated. The first infrared lamp panel 4 is evenly distributed inside the support shell 3 and is used to evenly irradiate the patient's head. When local treatment of the patient's head is required, the medical staff turns off the first infrared lamp panel 4 and turns on the second infrared lamp panel 502. There are four sets of second infrared lamp panels 502, which are evenly fixed inside four sets of rings 501. The medical staff manually pushes the rings 501 to rotate, which drives the second infrared lamp panels 502 to rotate, adjusting the irradiation angle and accurately irradiating the patient's head, thus achieving a targeted treatment effect.

[0041] After the second lamp panel is rotated to the designated angle, medical staff manually rotate the screw 604. The screw 604 drives the moving rod 602 to move, and the moving rod 602 drives the two sets of rubber pads 603 to move synchronously, so that the rubber pads 603 contact the outer wall of the support shell 3. Through the squeezing action of the threads, the friction between the rubber pads 603 and the support shell 3 is increased. The friction restricts the rotation of the ring 501, thereby fixing the irradiation angle of the second infrared lamp panel 502.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
