Description

Dynamic magnetic field physiotherapy device for relieving eye dryness and asthenopia symptoms Technical Field The invention relates to the field of medical electronic instruments, in particular to a dynamic magnetic field physiotherapy device for relieving eye dryness and asthenopia symptoms. Background At present, various relieving means and technical schemes exist on the market for aiming at common visual health problems such as dry eyes, lacrimation, asthenopia and the like. The technology mainly comprises the following steps of chemical agent intervention, such as artificial tears, anti-inflammatory eye drops and the like, wherein the effects of the chemical agent intervention are mainly temporary wetting or inflammation relieving, but the dependency, potential side effects and the problem of incapability of fundamentally regulating fatigue exist, physical optical means, such as blue-light prevention glasses, atomization humidifier and the like, the technology is mainly aimed at external environment stimulation or humidity improvement, the regulating effect on deep muscles and blood circulation of eyes is limited, and the traditional physical physiotherapy, such as hot compress eyepatches, eye massage devices and the like, promotes local circulation through thermal effect or mechanical compression, but the effect is concentrated on the surface layer, and the regulation on deep and targeted biological effect of eye tissues is lacking. In the technical field of eye physiotherapy by using a physical field, magnetic field physiotherapy is paid attention to due to the characteristics of non-invasiveness and good penetrability. The closest similar prior art at present is mainly a static magnetic field eye shield or a low-frequency alternating magnetic field eye massager. These devices typically employ an array of permanent magnets or single frequency electromagnetic coils that generate a static or simple time-varying magnetic field around the eye that is relatively fixed in strength and direction. The design is initially designed to alleviate symptoms by the action of the magnetic field that may be present to promote microcirculation and affect neuronal excitability. However, such existing magnetic field physiotherapy techniques have significant limitations in application to relieving complex ocular dryness, abnormal lacrimation and asthenopia syndrome, and the effect is often not durable or stable. The specific problems and reasons are as follows: 1. The magnetic field mode is single and is not matched with the physiological dynamics of eyes, and the magnetic field generated by the prior device is mostly in a static or simple repeated alternating mode. The discomfort symptoms of the eyes are often caused by multiple factors, including ciliary muscle spasm, abnormal meibomian gland function, unstable tear film, and nerve regulation disorder, which are all dynamic and complex physiological and pathological processes. Single and fixed magnetic field parameters (such as intensity, frequency and direction) are difficult to simultaneously adapt to the dynamic adjustment requirements of various pathological links, so that the physiotherapy effect is unilateral and limited. 2. The lack of pertinence and adaptability is that the magnetic field parameters provided by the prior art are usually preset and fixed, and cannot be dynamically adjusted according to the real-time eye state, fatigue degree or individual difference of the user. There are individual sensitivity differences in biological effects of the eye on the magnetic field, and the main symptoms (dryness or lacrimation) caused by different causes may differ in the response requirements to the magnetic field. The one-cut scheme with fixed parameters is difficult to realize accurate and personalized intervention, which is an important reason for large user experience difference and poor effect of the prior art device. 3. The prior eye-shield design covers the eye area, but the space distribution of the magnetic field generated by the internal magnet or coil is often not optimized enough, so that effective magnetic field energy is difficult to focus on key anatomical parts (such as meibomian glands at the eyelid margin and ciliary muscle area behind the eyeball). This results in partial therapeutic energy loss, insufficient stimulation intensity to deep tissues, and affects pertinence and efficiency of physiotherapy. Therefore, how to provide a magnetic field physiotherapy device which can generate dynamic change, has adjustable parameters and can act on the key target area of the eye more accurately, and the magnetic field physiotherapy device is a technical problem which needs to be solved by the person skilled in the art. Disclosure of Invention In order to solve at least one technical problem in the background art, the invention provides a dynamic magnetic field physiotherapy device for relieving eye dryness and asthenopia symptoms, which can be limited by a
