Description

A meibomian gland heating and fumigation device for dry eye syndrome

technical field

The invention relates to a medical device, in particular to a meibomian gland heating and fumigation device for dry eye syndrome.

Background technique

Dry eye syndrome refers to a general term for a class of diseases in which abnormal tear quality and quantity or dynamics lead to decreased tear film stability and ocular surface damage, resulting in ocular symptoms. Patients often have dry eyes and foreign body sensation. Other symptoms include burning sensation, itching, photophobia, red pain, blurred vision, easy fatigue, and sticky filamentous secretions.

The pathogenesis and pathological process of dry eye are complex. Pathological changes on the ocular surface, immune inflammatory response, reduction of sex hormone levels and the influence of the external environment are the main factors of dry eye. In recent years, it has been found that meibomian gland function is closely related to dry eye syndrome. The meibomian glands are located in the upper and lower eyelid conjunctiva of the human body and open at the eyelid margin. The meibomian glands secrete meibum to form the lipid layer of the tear film to prevent excessive evaporation of tears and promote the stability of the tear film. The tear film is composed of a lipid layer, an aqueous layer and a mucin layer. The outermost layer is a lipid layer. The lipid is mainly secreted by the meibomian glands to the eyelid margin and distributed on the surface of the eyeball through blinking movements. If the meibomian gland function is impaired, the quality of tear secretion is abnormal, which affects the stability of the tear film, shortens the tear film rupture time, and tears evaporate too quickly, thereby causing damage to the ocular surface and eventually leading to dryness. Occurrence of eye disease.

In recent years, with the increasing incidence of dry eye caused by blepharitis and meibomian gland dysfunction (MGD), this type of dry eye has attracted more and more attention from scholars at home and abroad. MGD is a chronic, diffuse meibomian gland abnormality that is usually characterized by obstruction of the terminal duct of the meibomian gland and/or changes in the substance or quantity of meibomian gland secretion. Chronic blepharitis is a common clinical disease, including lesions of the accessory glands of the eyelid margin, the mucocutaneous junction, and the meibomian glands. Blepharitis is a chronic inflammation of the eyelid margin caused by staphylococcal infection or seborrheic, meibomian gland secretion and tear film also play an important role in the pathogenesis of blepharitis. Both blepharitis and MGD disrupt the normal meibum secretion, causing excessive tear evaporation, which is the most common cause of evaporative dry eye. The rate of dry eye syndrome in patients with chronic blepharitis is 3 times higher than normal people. Blepharitis is often accompanied by the loss of meibomian glands and MGD, the quality and quantity of meibum decrease, the lipid layer of the tear film is damaged, and the tear fluid evaporates excessively, leading to dry eye syndrome. Blepharitis, MGD and dry eye syndrome can be mutually causal . Treatment is mainly to dredge the meibomian glands and improve the function of the meibomian glands. At present, a commonly used dry eye syndrome is usually treated by physical cleaning of the eyelids, local application of various artificial tears and corticosteroid eye drops, etc., combined with oral antibiotics and hot compress massage. The treatment of meibomian gland dysfunction mainly depends on physical measures, including heat compress, massage and scrubbing. Eyelid massage and hot compress can dissolve fatty secretions, promote the discharge of meibomian gland secretions, make the tear film lipid layer uniform, increase tear film breakup time, and improve irritation symptoms.

Hot compresses are commonly used to apply hot towels to the eyelids. The specific steps are to clean the eyes, soak the towels in hot water at 40-45°C, wring them out and apply them to the eyes, or put a semi-dry wet towel in Microwave for 1-2 minutes. The towels should not be too hot to prevent scalding the skin, and the towels are generally changed every 5 minutes. The hot compress time is 15-20 minutes each time, 3-4 times a day, which can not only promote the blood circulation around the eyes, reduce eye fatigue, but also promote the smooth opening of the meibomian glands, so as to partially relieve dry, astringent and congested eyes and other symptoms.

In the above-mentioned heating method, the patient needs to change towels and warm physiological water repeatedly, and the operation is cumbersome. Moreover, patients with severe dry eye syndrome, such as patients with severe blockage of meibomian glands or ineffective eyedrops, must go to the hospital for consultation. Professional medical staff squeeze the meibomian glands with a glass rod to open the opening of the meibomian glands and press the patient's eyelids and conjunctiva. Improper pressure can cause eye damage. How to effectively heat the meibomian glands can promote the discharge of the secretions accumulated in the meibomian glands, so as to relieve the patient's eye discomfort symptoms, safe and effective for the treatment of dry eye, and prevent the occurrence of blepharitis and MGD become an urgent problem to be solved.

In summary, how to provide a meibomian gland heater and drug fumigation combined with anti-inflammatory effects, the key is to strengthen the treatment from the etiology and pathogenesis, so as to improve the safety and effectiveness of dry eye treatment, especially for dry eye To provide an effective, minimally invasive and efficient treatment method for patients with eye diseases complicated by blepharitis and meibomian gland dysfunction is an urgent problem to be solved in this field.

The principle of the infrared heating plate selected in the present invention:

Infrared rays are called life rays, which can pass through the skin and directly generate heat effects on muscles and subcutaneous tissue. Accelerate the circulation of blood substances, increase metabolism, anti-inflammatory and pain relief, and produce massage effects, etc. Infrared rays are mainly used to treat diseases because they can mobilize the body's own disease resistance from different levels. Among them, near-infrared rays have the shortest wavelength, deep penetration and strongest infrared rays, which can effectively help human blood microcirculation, and at the same time stimulate mitochondrial activity to generate more ATP and promote tissue metabolism. The thermal effect of the infrared heating plate of the present invention promotes the diffusion and penetration of traditional Chinese medicine, and "introduces the medicine deep into the string" to the eyelids, periorbital and meibomian glands, so that the active ingredients of the medicine can quickly penetrate into the eyes through the capillaries of the eyelid skin The surrounding tissue is absorbed, which can greatly improve the curative effect.

The pharmacology of the Chinese medicine raw material selected in the present invention is as follows:

Dendrobium: It is a traditional Chinese medicine, derived from the stems of Dendrobium orchidaceae, a variety of plants belonging to Dendrobium, slightly cold in nature. Benefits the stomach and promotes body fluid, clears away heat and nourishes yin, and mainly treats body fluid loss due to febrile disease, dry mouth and polydipsia, asthenia heat after illness, and yin damage to eyesight. Dendrobium stems contain a variety of alkaloids, polysaccharides, amino acids and starch, which have certain antipyretic and analgesic effects; can promote gastric juice secretion and aid digestion; enhance metabolism and anti-aging effects. Traditional Chinese medicine believes that the essence of the internal organs and six internal organs is injected into the eyes through the blood vessels, and the liver "opens up to the eyes". The physiology and pathology of the eyes are closely related to whether the liver's yin essence is full or not. If the yin essence of the liver is abundant, the eyes will be bright and piercing, and the movement will be flexible, radiant, and the person will appear energetic; if the yin essence is insufficient, the eyes will be dull, dry, or blurred. , or night blindness, etc. Shijie has the function of nourishing yin and nourishing the liver, so it has been used as a good product for eye care by doctors of all ages.

Trichosanthum Fen: sweet, slightly bitter, slightly cold in nature, returns to the lung and stomach meridians; specific effects are clearing heat and purging fire, promoting body fluid and quenching thirst, clearing lung and moistening dryness, detoxifying and eliminating carbuncle, etc. Trichosanthes relieves stagnant heat in the five viscera, such as excessive heart-fire and dry tongue and mouth, excessive lung-fire and swollen throat and throat, excessive spleen-fire and swollen mouth, tongue and teeth, and phlegm-fire and restless cough. If the liver-fire is distended and drained, the bones of the kidney-fire are steaming and hot, or the carbuncle is ulcerated but the heat toxin persists, or the five jaundice, the body and the eyes are yellow, and the small water is dripping or astringent, it is all caused by the stagnation of fire and heat. Cause, only this agent can open stagnation, reduce phlegm fire, and can cure it. In addition, its nature is sweet and cold, and it is good at curing thirst. It can be used to cure deficiency and thirst from tonic, to cure fire thirst from cold medicine, to cure thirst from qi medicine, and to cure polydipsia from blood medicine, which is the key medicine for thirst.

Chrysanthemum: sweet, bitter, slightly cold. Return lung, Liver Channel. Dispersing wind and clearing away heat, calming liver and improving eyesight. For anemopyretic cold, headache and dizziness, conjunctival congestion and swelling pain, dim eyesight.

Wild chrysanthemum: Wild, mostly grows on roadsides, hills, wasteland, hillsides, etc., and is distributed in most parts of the country. Among them, Xinxian County in the Dabie Mountains has always been the main production area of wild chrysanthemums. Every September and October, the mountains are full of wild chrysanthemums. Wild chrysanthemum is also used for medicine, but its efficacy is quite different from that of the prescription "chrysanthemum". Wild chrysanthemum is bitter, pungent and slightly cold in nature, returns to the liver and heart meridian, and its main effect is to clear away heat and detoxify, and treat surgical infectious diseases such as carbuncle, furuncle, red eyes, scrofula, pemphigus, and eczema. Because of its strong heat-clearing and detoxifying power, it is good at treating various boils and carbuncles, and it also has therapeutic effects on prostatitis. In addition, wild chrysanthemum, like chrysanthemum, also has anti-inflammatory, anti-viral, antihypertensive, and lipid-lowering effects.

Return liver, kidney meridian, have the effect of invigorating liver and kidney, strengthening muscles and bones, promoting blood circulation and dredging menstrual flow, diuresis and treating stranguria. The Achyranthes knuckle polysaccharide has immune-regulating and anti-tumor effects, has activity on granulocytes, macrophages, monocytes, natural killer cells and T cells, and can enhance the humoral immunity of the body, induce interleukin, tumor necrosis factor, interference High expression of immune factors such as hormones.

Radix Rhizoma: sweet in the mouth, bitter, cold in nature, GUIXIN, liver, kidney meridian, has the effect of clearing away heat and cooling blood, removing blood stasis and promoting regeneration, nourishing yin and promoting body fluid.

Lycium barbarum: sweet, flat. Return liver, kidney channel. Indications nourish the liver and kidney, benefit essence and improve eyesight. It is used for consumptive essence deficiency, soreness of waist and knees, dizziness and tinnitus, internal heat and thirst, blood deficiency and chlorosis, and blurred vision. Lycium barbarum contains 14 kinds of amino acids, and contains special nutrients such as betaine, maize flavin, physalis erythromycin, etc., which make it have extraordinary health care effects. Lycium barbarum is rich in carotene, multivitamins, calcium, iron and other essential nutrients for healthy eyes, so it has the effect of improving eyesight, commonly known as "bright eyes". Physicians of the past dynasties often used wolfberry to treat blurred vision and night blindness caused by liver blood deficiency and kidney yin deficiency. The famous prescription "Qiju Dihuang Pills" uses the fruit of wolfberry as the main drug.

The working process of the present invention is as follows: after the patient places the spectacle frame of the wearable component on the eyelids and periorbital skin according to the method of wearing frame glasses, the distance between the spectacle frame and the eyelid skin is about 5-10 cm, and the adjustable fixing belt is adjusted to a suitable length and fixed. , the operator only needs to place the mirror cup (the pre-prepared traditional Chinese medicine preparation filtrate soaked in the absorbent paper and fit the bottom of the mirror cup) into the eyelids and periorbital skin of both eyes, plug the plug into the 220V AC power supply, Set the temperature and working time of the infrared heating plate corresponding to the eyelid skin, the heat will be transferred to the eyelid skin and meibomian gland, and drive the medicine on the drug component to perform fumigation treatment, thereby realizing the unobstructed opening of the meibomian gland and replenishing the moisture of the ocular surface , Promote the absorption and utilization of traditional Chinese medicine drugs. The treatment method is hot fumigation for 15-30 minutes each time, hot compress once a day, 7 days as a course of treatment, and 3 courses of treatment as a cycle.
