Description

A method for promoting retinal blood circulation based on heat Technical Field

[0001] This invention relates to the field of physical therapy technology, specifically a method for promoting blood circulation in the fundus based on heat. Background Technology

[0002] Fundus blood circulation refers to the blood flow system supplying the retina, choroid, optic nerve, and other retinal tissues. It is mainly composed of the central retinal vascular system and the ciliary vascular system. As one of the most metabolically active tissues in the human body, the retina requires a large amount of oxygen and energy for the high-frequency renewal of its photoreceptor cells and the continuous transmission of visual signals. These nutrients depend entirely on the continuous supply of blood from the fundus circulation. Normal fundus blood circulation can promptly remove metabolic waste, maintaining the integrity of the retinal structure and the stability of its function. When fundus blood circulation is impaired, it can lead to retinal ischemia and hypoxia, resulting in blurred vision, decreased visual acuity, and in severe cases, even developing into various blinding eye diseases such as retinal vein occlusion, diabetic retinopathy, and ischemic optic neuropathy.

[0003] In existing technologies, methods to improve retinal blood circulation mainly fall into three categories: drug therapy, surgical treatment, and physical therapy. Drug therapy typically uses vasodilators or anticoagulants, but long-term use may cause systemic side effects. Surgical treatments, such as laser photocoagulation or vitrectomy, are invasive procedures with high risks and high costs. As for physical therapy, while traditional hot compresses can relieve ocular surface fatigue to some extent, the heat is difficult to penetrate to the deep tissues of the retina, and the temperature control is not precise, which can easily cause epidermal burns or poor treatment results.

[0004] In addition, existing physical therapy methods are mostly based on experience and lack quantitative evaluation standards and individualized control mechanisms, making it difficult to provide precise and effective interventions for different patients' fundus blood flow conditions. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a method for promoting retinal blood circulation based on heat, aiming to solve the technical problem of the difficulty in safely, effectively, and controllably promoting retinal blood circulation in existing technologies, thus necessitating the use of this heat-based method for promoting retinal blood circulation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for promoting retinal blood circulation based on heat, comprising the following steps: obtaining an ocular treatment area and a first blood perfusion volume and current temperature of the ocular treatment area; obtaining a heating temperature based on the current temperature; heating the ocular treatment area at the heating temperature, and applying a preset pressure or a preset frequency of vibration to the ocular treatment area.

[0007] In some embodiments, the application time of the preset pressure is synchronized with the heating time of the eye treatment area, or the application time of the preset frequency vibration is staggered with the heating time of the eye treatment area.

[0008] In some embodiments, the method further includes: after heating for a preset time, obtaining a second blood perfusion volume of the eye treatment area; and determining the treatment effect of the eye treatment area based on the difference between the second blood perfusion volume and the first blood perfusion volume.

[0009] In some embodiments, determining the treatment effect includes: when the increase in the second blood perfusion volume compared to the first blood perfusion volume reaches 20% or more, the treatment is deemed effective.

[0010] In some embodiments, obtaining the heating temperature based on the current temperature includes: adjusting the output power of the heating element through a closed-loop control circuit based on the difference between the current temperature and a preset target temperature, so that the temperature of the heating element is the difference between the current temperature and the preset target temperature.

[0011] In some embodiments, the preset target temperature ranges from 38°C to 45°C.

[0012] In some embodiments, the eye treatment area is a surface projection area corresponding to Zanzhu, Yuyao, Sizhukong, Sibai and Taiyang.

[0013] In some embodiments, the preset frequency vibration frequency range is 20Hz to 100Hz, and the preset pressure range is 10mmHg to 30mmHg.

[0014] This invention provides a method for promoting retinal blood circulation based on heat, which has the following beneficial effects: By applying precise and controllable heat to the treatment area of ​​the eye, it can first safely and effectively dilate the capillaries and microarteries around the eye, significantly increasing the blood perfusion rate and volume of the retinal tissue, thereby quickly relieving discomfort symptoms such as eye fatigue and dryness, and can provide an adjunctive treatment for chronic retinal diseases such as diabetic retinopathy; secondly, by introducing a closed-loop temperature control and gradient heating strategy, it ensures that the treatment process is always within a safe range of 38°C to 45°C, which can both ensure the deep penetration of the thermal effect and avoid thermal damage to the ocular surface tissue due to excessive temperature, greatly improving the safety and individual adaptability of the treatment.

[0015] Figure 1 is a schematic diagram of the process of the present invention.

[0016] Figure 2 is a schematic diagram of the process of an embodiment of the present invention. Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please refer to the flowchart in Figure 1. The present invention provides a technical solution for a method to promote retinal blood circulation based on heat: A method to promote retinal blood circulation based on heat includes the following steps: obtaining the eye treatment area and the first blood perfusion volume and current temperature of the eye treatment area; obtaining the heating temperature according to the current temperature; heating the eye treatment area according to the heating temperature, and applying a preset pressure or a preset frequency of vibration to the eye treatment area.

[0019] This method achieves precise acquisition of baseline data before treatment by obtaining the first blood perfusion volume and current temperature of the ocular treatment area, providing a quantitative basis for subsequent individualized treatment; it dynamically obtains the heating temperature based on the current temperature to ensure that the applied heat always matches the patient's real-time condition, avoiding insufficient efficacy or safety risks due to temperature deviation; while precisely controlling the temperature and heating, it applies preset pressure or preset frequency vibration, and through the synergistic effect of thermal effect and physical stimulation, it expands the microvessels of the fundus to promote blood perfusion on the one hand, and relaxes the periocular muscles and accelerates lymphatic return on the other hand, significantly improving the efficiency of ocular microcirculation improvement. In some embodiments, the application time of preset pressure is synchronized with the heating time of the ocular treatment area, or the application time of preset frequency vibration is staggered with the heating time of the ocular treatment area.

[0020] This setup allows for flexible selection of a synergistic mode of physical intervention and thermotherapy based on treatment needs and patient tolerance. It can simultaneously enhance the thermal effect to promote blood circulation, while the alternating action can avoid adaptive fatigue caused by continuous stimulation, thereby improving the comfort and effectiveness of treatment.

[0021] In some embodiments, the method further includes: after heating for a preset time, obtaining a second blood perfusion volume in the eye treatment area; and determining the treatment effect of the eye treatment area based on the difference between the second blood perfusion volume and the first blood perfusion volume.

[0022] This setup allows for the objective quantification of blood flow changes before and after treatment, providing data support for efficacy evaluation, facilitating doctors' or patients' understanding of the actual treatment effect, and enabling precise feedback and adjustments to the treatment.

[0023] In some embodiments, determining the treatment effect includes: when the increase in the second blood perfusion volume compared to the first blood perfusion volume reaches 20% or more, the treatment is deemed effective.

[0024] This approach provides a clear quantitative standard for efficacy, making treatment effects measurable and comparable, which helps in the standardization of clinical research and the optimization of individualized treatment plans.

[0025] In some embodiments, obtaining the heating temperature based on the current temperature includes: adjusting the output power of the heating element through a closed-loop control circuit based on the difference between the current temperature and a preset target temperature, so that the temperature of the heating element is the difference between the current temperature and the preset target temperature.

[0026] This setting allows for dynamic adjustment of heating power based on real-time temperature, ensuring that the temperature of the eye treatment area is accurately and stably maintained at the preset target value, avoiding temperature fluctuations or the risk of overheating, and achieving safe and reliable personalized temperature control treatment.

[0027] In some embodiments, the preset target temperature ranges from 38°C to 45°C.

[0028] This setting limits the treatment temperature to a safe range that effectively dilates blood vessels and promotes blood circulation without causing thermal damage to the ocular surface tissue, ensuring both effectiveness and safety, and making it suitable for long-term, repeated use. For example, specific values ​​could be 38.5℃, 42℃, or 44℃. 38.5℃ is suitable for gentle heat therapy for people with sensitive skin, 42℃ is a standard treatment temperature that strikes a good balance between comfort and efficacy, and 44℃ is suitable for intensive treatment scenarios requiring deeper heat penetration.

[0029] In some embodiments, the eye treatment area is the body surface projection area corresponding to Zanzhu, Yuyao, Sizhukong, Sibai and Taiyang.

[0030] This setup precisely positions the heat therapy area at key acupoints according to traditional Chinese medicine meridian theory. By stimulating these acupoints with heat, it further regulates the flow of qi and blood, leveraging the synergistic effect of meridian unblocking and physical heat therapy to enhance the overall efficacy of the treatment.

[0031] In some embodiments, the preset frequency vibration frequency range is 20Hz to 100Hz, and the preset pressure range is 10mmHg to 30mmHg.

[0032] For example, the vibration frequency can be 25Hz, 50Hz, or 80Hz; the preset pressure can be 12mmHg, 20mmHg, or 28mmHg. This setting limits the physical intervention parameters to a range that effectively relaxes the muscles around the eyes and promotes lymphatic drainage without causing discomfort or damage, ensuring the safety and effectiveness of the physical intervention and synergistically improving retinal blood circulation with thermotherapy. Specifically, 25Hz low-frequency vibration is suitable for sensitive individuals or the initial adaptation phase; 50Hz mid-frequency vibration achieves a good balance between comfort and therapeutic effect; and 80Hz high-frequency vibration is suitable for intensive treatment scenarios requiring deep tissue stimulation. 12mmHg low pressure is suitable for mild massage needs; 20mmHg medium pressure achieves a good balance between comfort and therapeutic effect; and 28mmHg high pressure is suitable for auxiliary treatment scenarios requiring stronger physical stimulation.

[0033] It is worth noting that all standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The models of electrical structure equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application. In addition, the circuit connection adopts conventional connection methods in the prior art. The supporting electrical structures such as the control, current detection, position feedback, predicted voltage synchronization and parameter adjustment of the electrical equipment are all existing technologies, such as PLC controllers and module structures, so they will not be described in detail here.

[0034] The following describes a specific embodiment of this application with reference to Figure 2: According to the flowchart of Embodiments 1-3 in Figure 2; Embodiment 1: Method for promoting fundus blood circulation through basic thermotherapy This embodiment describes a basic application scenario, which is suitable for people in sub-healthy states such as visual fatigue and dry eyes caused by prolonged use of the eyes, in order to improve fundus blood perfusion.

[0035] Step 1: Treatment Area Location. Determine the treatment area for the subject's eyes. This area is around both eye sockets, encompassing the surface projection areas of Zanzhu, Yuyao, Sizhukong, Sibai, and Taiyang (corresponding to acupoints around the eyes in Traditional Chinese Medicine).

[0036] Step 2: Apply controlled heat. Using a medical-grade heat therapy device with temperature control, apply the heat therapy head (or heat radiation source) to the treatment area. Set the heating temperature to 42°C (this temperature is within the safe and effective range of 38°C to 45°C as described in claim 9) and continue heating for 20 minutes. The heat is conducted through the skin tissue to the deep retinal blood vessels, causing local capillaries and arterioles to dilate.

[0037] Step 3: Hemodynamic monitoring. Before treatment, immediately after treatment, and 30 minutes after treatment, Doppler flowmeters were used to measure blood flow velocity and flow in the fundus (e.g., central retinal artery or short posterior ciliary arteries). Results showed that immediately after treatment, fundus blood perfusion increased by an average of 25% compared to the baseline value before treatment, and maintained an increase of 15% after 30 minutes, indicating that this method effectively promotes fundus blood circulation.

[0038] Example 2: Gradient heating combined with acupoint hot compress. This example is for sensitive skin people who need gentler heat stimulation, or for clinical treatment scenarios that require more precise control.

[0039] Step 1: Initial Assessment and Parameter Setting. An infrared thermotherapy device with real-time temperature feedback is used. First, the device probe is placed on the skin around the subject's eyes, and the initial epidermal temperature (e.g., 32℃) is obtained through the device's built-in temperature sensor. Based on the preset gradient temperature rise curve, the target temperature for the first stage is set to 38℃, the target temperature for the second stage to 43℃, and the target temperature for the third stage to 45℃.

[0040] Step 2: The gradient heating process starts the equipment, and the heat generation unit begins to work.

[0041] Phase 1 (0-5 minutes): The device outputs low power to slowly raise the skin temperature in the treatment area from the initial value to 38°C and maintains it for 2 minutes to allow the subject to fully adapt.

[0042] The second stage (6-15 minutes): Based on the PID closed-loop control algorithm, the output power is automatically adjusted to raise the temperature and stabilize it at 43℃. At this temperature, the heat penetration is enhanced, which can effectively dilate deep blood vessels around the eyes.

[0043] Phase 3 (16-20 minutes): If the subject experiences no discomfort, the temperature is increased to 45℃ and maintained for 5 minutes to consolidate the therapeutic effect. Throughout the process, if the local skin temperature exceeds 45.5℃, the system immediately reduces its output power to prevent burns.

[0044] Step 3: Verification of the effect After treatment, the changes in the diameter of the retinal blood vessels in the subjects were observed by fundus camera. The diameter of the blood vessels was significantly thickened, indicating that blood circulation was effectively promoted.

[0045] Example 3: A method for promoting fundus blood circulation through thermotherapy combined with physical intervention. This example is applicable to subjects with eyelid edema or severe eye fatigue. The therapeutic effect is enhanced by the synergistic effect of thermotherapy and mechanical vibration.

[0046] Step 1: Simultaneous Intervention Parameter Setting. While using the hyperthermia method as described in Example 1 or 2, activate the mechanical vibration module integrated with the hyperthermia device. Set the vibration frequency to 50Hz (range 20Hz-100Hz), the vibration mode to intermittent vibration (vibrate for 3 seconds, pause for 1 second), and the vibration amplitude to low (approximately 0.5mm).

[0047] Step 2: During the combined treatment, the thermotherapy device is fixed to the eye, while a constant temperature of 42℃ heat and 50Hz mechanical vibration are applied simultaneously. The vibration acts on the soft tissues around the eye, further relaxing muscles and promoting lymphatic drainage, synergistically accelerating microcirculation in the eye in conjunction with the heat effect. The treatment lasts for 15 minutes.

[0048] Step 3: Efficacy Assessment. Ocular blood flow imaging was performed before and after treatment. Results showed that the end-diastolic blood flow velocity of the ocular arteries in the combined treatment group was approximately 12% higher than that in the simple thermotherapy group, indicating that the additional physical intervention could further enhance the improvement of fundus blood circulation.
