粉尘螨过敏预防

粉尘螨过敏预防 What should be paid attention to the dust mite, the house dust mite? How to treat? Mites die in a dry environment with less than 15% humidity and cannot reproduce further in low temperatures. More for traditional pesticides so even now, they have adaptability and resistance, so that cannot be eliminated completely, but do well family and personal hygiene, is still economic effective pest control method. Specific methods are often keep the bedroom and studio ventilated dry, frequently change clothes, bedding, regular exposure to flap, bedding, mattresses, things such as pillow core, straw mat, carpet. In the spring and summer, often will grass, bamboo in the sun drying, flap, or with 75% ethanol to wipe, or fine piece of camphor fragrant insect repellent product under the mattress or mat. Use vacuum cleaner to absorb dust from carpet often, still can use the deworming agent of pyrethrin to spray on carpet, or use cotton gauze to dip in the oil to wipe carpet. It is best not to let the pet enter the bedroom, and regularly bathe and disinfect the pet. Here are the details Keynote: Dr. Wei qingyu Reduce the life and work and the content of dust mites in the environment is very important in patients with allergic to dust mites, can control measures to reduce the amount of suction dust mites scales and waste, to prevent and reduce the incidence, reduce the number. The optimum conditions of dust mites are 17 ~ 30 ? temperature, relative humidity 75% ~ 80%, house dust mites feed on human body fall off or animal dander, multiply faster in the bed and bedroom carpet, a person daily generate 0.7 grams dander. Dust mites feed on all kinds of food dust. According to the conditions and food sources of dust mites, the prevention of dust mites can be followed by two principles: the temperature and humidity of the environment. Dust mites terms of death is greater than 35 ? temperature, continuous 24 hours or less than 0 ?, humidity is less than 50% or greater than 50% cannot reproduce; The second is to cut off its food source and eventually reach three goals: one: reducing the total number of living mites; 2: reducing the level of allergens in mites; Three: reduce people's exposure to the first two. Dust mites allergic patients according to the specific environment of their life and work effective method or a variety of methods and used to control the dust mites live and grow at the same time. Reduce indoor relative humidity, control the relative humidity below 50%, is the most common method that control mite and allergy source level. Easier to control humidity ratio control temperature; test showed that under 40% or 50% relative humidity in a row, even if the temperature at 25 ~ 34 ?, the adult mites in 5 ~ 11 days will die from dehydration. In the mountainous country or the north of the Middle East, few mites and mite allergens exist in these dry areas. Suggested that the indoor use high-performance moisture absorption machine and air conditioner to reduce the amount of relative humidity and mites, both practical and effective, often should clean or replace air conditioner dust mask or the net, reduce dust mites breeding. Use of packaging: the use of special anti-mite materials for mattresses and pillows is an effective way of reducing exposure to dust mites and their allergens. For allergic patients, this method is recommended for packaging materials made of plastic, breathable materials, tiny fabric fibers or non-woven materials. The aperture of the fabric is very important when purchasing pillows and mattress packaging materials. The ideal material should be a comfortable, breathable fabric that permeates the steam and prevents the mite and mite allergens from passing. The mite's width is generally greater than 50 microns, so the fabric is less than or equal to 20 microns to block the passage of all the mites. There is a bed cover, pillow case, etc. High quality, feather pillow, feather and down jacket due to its covering the surface of the fabric is very dense, can prevent dust mites into and dust mites in breeding (eat less than scurfy, etc) of the body. 3, bedding, cleaning, drying and dry cleaning, seat covers, pillowcases, blankets, mattress cover, such as a week, equal to or higher than 55 ? hot water wash can kill mites and remove most mite allergen. Rinse with warm water or cold water does not kill the majority of the mites, but most allergens are removed because most of the allergens are water-soluble. Tumble dry clothes than 55 ?, more than 10 minutes to kill all the mites. Washing your hair every day is also a good way to control dust mites. 4, carpets, curtains and home soft decoration to frequently change, cleaning, carpet, curtain and home decoration fabric have accumulated detritus fragments and keep moisture, has provided the ideal habitat for mites breeding. In moist area should not use carpet, window (cloth) curtain or shade shade, should change to shutter. Household adornment fabrics should be replaced with vinyl resin or leather cushion, furniture can be used wooden furniture. Vacuum of carpet vacuuming: if the family is unwilling or economically not allowed to change carpet, should vacuum dust once a week, and often change vacuum bag. Conventional vacuum dust removes the surface mite and allergens, but does not significantly reduce the number of living mites, nor does it remove the underlying allergens. 6, frozen soft toys and small items: in - 17 ? ~ ~ 20 ? frozen soft toys and small items such as pillows and special clothes for at least 24 hours, is an effective method to kill mites on these items. After freezing in your home, wash these items to remove the dead mites and allergens. Placing mattresses and pillows outdoors for 24 hours in the cold winter can also kill mites. Air cleaning/filtration: the main constituent of dust is mite. Mite allergens are mainly related to dust particles larger than 20 mu m in diameter. Air flow makes it airborne particles that cause allergies when inhaled. When the air is cleaned or filtered, make sure that the room air is flowing and the dust rises so that it can be cleaned or filtered. 8, not indoor breeding cats, dogs and other pets: a small animal body has the right temperature, humidity, a large amount of dander and abundant food source of dust mites, so small animal breeding a large number of mites on the body, can also carry everywhere in the interior, spread everywhere. 9, chemical reagents: at present, the use of chemical reagents to remove acarid allergen and the result is not very satisfied, it must be active ingredients directly to the mites live. The main one is: phenylmethylbenzoic acid, tetris hydrate, thorium, thorium reagent, extinguishing forest and transsexual agent, etc. The indoor safety of these mites will also need to be further confirmed, and repeated applications will lead to the emergence of resistant mites. Is 10 and the control of dust mites allergic disease: as part of the overall treatment of perennial allergic rhinitis, asthma or atopic dermatitis patients, if allergic to mite, through inhalation therapy and specific desensitization treatment at the same time, to control the indoor mite allergen, can according to their degree of disease, patients with local climate conditions and personal life and living environment. < prompt > Bed, carpet and home wear are the three most important places to go. Conditions for the growth of dust mites: humidity, temperature and ventilation. Measures to control the allergens of dust mites: to make personal hygiene: to bathe frequently and change clothes frequently; (2) make the bedroom: frequently wash bedding (ordinary washing powder, 25 ? and at least 5 minutes, take a bath once a week). Pillow: seal with anti-mite material; Mattress: wrap in a breathable fabric or plastic (paper), vinyl resin or plastic seal mattress spring; Indoor cleaning: vacuum vacuuming once a week (with a mask and 20 minutes after the vacuum). Note: the vacuum cleaner USES a quality bag (double) or a high performance air filter in the outlet. The long-term strategy of controlling the mite and its allergens: reducing the relative humidity of the room: air conditioning, suction wet machine, or ventilation according to season and climate. Change carpet: use polishing wood floor, vinyl resin floor, floor tile. Replace furniture decoration: leather, vinyl resin, wood furniture. Change the curtain: use the shutters that can be scrubbed instead, try not to live in the basement. Points of allergy to dust mites: Dust mites are the world's strongest allergens. More than 80 percent of all coughs, wheezing and dust mites are related to allergies. 3 and the growth of dust mites is the ideal temperature 25 ?, humidity is 75%, lower than 60% can't breed, less than 50% could live. Main living in dust, damp furniture, carpet and bed. It mainly feeds on human or animal dandruff. Controlling dust mites and their allergens can reduce the onset of disease. The treatment of dust mites is effective. You can avoid worsening allergies (from rhinitis to asthma) and multiple allergies (from a single allergy to allergies to multiple allergens).
