What are the disinfectants?
Purple potion is 2% methyl violet solution, also called gentian violet. This solution has the function of accelerating wound scabbing and healing, and is often used for superficial skin and mucosal infections. Precautions: ① This solution is not suitable for mucous membrane or open wounds, especially large-area wounds, which may induce skin cancer due to its large volume; ② Not suitable for facial skin, it will affect the appearance after application, so use it as little as possible.
kind
1, hydrogen peroxide is hydrogen peroxide, which has the function of disinfection and sterilization.
Precautions: ① The concentration is 3%, which is high and easy to burn the affected skin; (2) When it is used for superficial local wounds with certain infection, its blood, pus and so on. It will easily reduce its bactericidal power; ③ Unstable properties, short storage time and easy failure.
2. Boric acid water 3% Boric acid solution has cleaning, astringent and bacteriostatic effects, and is often used for washing and cleaning skin, mucous membranes and wounds, gargling stomatitis, acute eczema, acute exudative dermatitis and scalding wet compress.
Precautions: ① Don't use it widely and for a long time, and don't use it for babies or eyes; (2) Pay attention to the concentration, too high concentration will have a * * * effect.
3, soapy water soapy water has a specific disinfection effect.
Precautions: ① The wounds bitten by dogs can be disinfected with 20% soapy water, which can neutralize, wash and inactivate rabies virus to a certain extent; ② After mosquito bites, washing with soapy water can relieve itching and local symptoms.
4, salt water only has the function of cleaning the wound, and has no disinfection effect.
Precautions: After washing, some commonly used external disinfectants, such as 2% iodine or 75% alcohol, should be applied to effectively sterilize and prevent wound infection.
Simple method for cleaning skin wounds: Add 1 g edible salt into 100 ml cold boiled water to prepare 1% physiological saline. If it can be washed with 0.9% physiological saline, it will be ideal. Because saline with a concentration of about 1% has the same concentration as sodium chloride in human blood, it has no * * effect on wounds and will not cause human cells to burst or shrink due to water loss.
What brands of disinfectants are there?
Disinfectants are not suitable for domestic use.
Now many people have 84 disinfectant, intravenous drip, peracetic acid, lysol, bleaching powder, potassium permanganate (PP powder) and other disinfection and sterilization drugs at home.
Misunderstanding: Dr. Zhu said that most people don't know what kind of disinfectant is suitable for home use, how much to use each time, and how to deal with the water, so they are blind when choosing it, and they are more casual when using it, so they can use as much as they want. In fact, if disinfectants are used improperly at home, it will cause a lot of trouble.
Expert correction: At present, the commonly used disinfectants mainly include peracetic acid, Lysol and 84 disinfectant. Dr. Zhu said that these disinfectants have different chemical compositions and disinfection targets, and it is best to use them under the guidance of professionals. If it is disinfected by the family itself, it must be used in strict accordance with the proportion of the instructions. The stronger the disinfectant, the more effective it is.
Disinfectant, like peracetic acid, is mainly used in hospitals and public places, such as floors, walls, doors and windows, etc. It is corrosive and not suitable for household disinfection. If you have a car at home, you can spray 0.5% peracetic acid solution to disinfect the exterior surface and interior space of the car. It should be noted that peracetic acid is corrosive and bleaching, and it is best not to use it for washing clothes at home. And 84 disinfectant must be diluted 200 times with water when it is used, which is quite corrosive. Therefore, Dr. Zhu believes that if there are no patients with infectious diseases such as hepatitis and tuberculosis at home, it is best not to use 84 disinfectant. But the washing machine at home can be disinfected with 84 disinfectant every 2-3 months.
Relatively speaking, dewdrops and Lysol are more suitable for home use. Drip and Lysol are mild in nature, and soluble in water can kill bacterial propagules and some lipophilic viruses. Generally, 3-5 drops of water can be added to a drum of a washing machine, and water can be added to make a solution of 1%-5%. Soak clothes and sheets in liquid for 30-60 minutes, and then wash them with water. When wiping indoor furniture and floors, you can use 1%-3% solution to wipe or spray.
If the home is only partially cleaned and there is no large-scale disinfection, then potassium permanganate (PP powder) and bleaching powder solution can be used. 1%-3% bleaching powder solution can be used to spray or wipe bathrooms and toilets; 0.5% bleach solution can also soak bowls and cups, spittoons, bedpans, contaminated shirts and sheets. And it can achieve the purpose of disinfection in half an hour. Potassium permanganate is most suitable for disinfection of fruits and vegetables, but the soaking time must be more than 5 minutes.
In fact, Dr. Zhu does not recommend that you use these chemical methods for disinfection. On the contrary, opening windows frequently, wiping furniture with wet cloth and mopping the floor are the best disinfection methods. On the one hand, ventilation can breathe fresh air, and wet wiping can also eliminate dust in the air, thus eliminating bacteria; On the other hand, it also avoids our frequent contact with toxic chemicals and prevents furniture from being corroded.
Experts remind: most families will use disinfectant in large quantities, or they are always afraid of incomplete disinfection. As we all know, many disinfectants are corrosive to furniture and floors, and the smell of disinfectants will linger at home for several days. In fact, this smell will gradually weaken people's resistance.
In order to save money, many families do not pay attention to the use of chlorine-containing disinfectants. Dr. Zhu said that the biggest advantage of this chlorine-containing disinfectant is its obvious bactericidal effect. But at the same time of sterilization, chlorine-containing disinfectant will remain in the air, will not volatilize, and will pollute the water source. What is even more frightening is that its three effects-carcinogenesis, teratogenesis and gene mutation-will also cause considerable harm to the human body.
In addition, some people don't want to use disinfectant, but use air freshener. In fact, the air freshener has no bactericidal effect at all, it can only cover up the odor in the room. But long-term use of air fresheners will make people feel headache and nausea. If there are people with allergies at home, it is easy to cause allergies, asthma and other diseases.
Special recommendation: self-made "disinfectant" can be used for air disinfection without chemical solvent disinfection. For example, heating white vinegar to fumigate the room or lighting it with moxa sticks is also a good way.
What are the commonly used chlorine-containing disinfectants?
Chlorine disinfectants can be divided into organic chlorine disinfectants and inorganic chlorine disinfectants. Organic chlorine-containing disinfectants include sodium dichloroisocyanurate, di (tri) chloroisocyanuric acid and chloramine -T toluene sulfonamide sodium. Inorganic chlorine-containing disinfectants include liquid chlorine, sodium hypochlorite NaClO.5H2O, bleaching powder CaCl 2 and bleaching (white) powder concentrated solution Ca (clo) 2 2h2o. The common methods are: trisodium phosphate chloride: soaking method: put the articles to be disinfected into a container filled with disinfectant and cover it; Wipe method: large items and other items that cannot be disinfected by soaking method are disinfected by wiping method; Spraying method: generally pollute the surface of goods and spray disinfectant; Dry powder disinfection method: directly add chlorine-containing disinfectant dry powder to the feces to disinfect the feces.
What are the disinfectants?
Common disinfectants in the market have experienced the development process of the first generation, the second generation, the third generation and the fourth generation. The active ingredient in disinfection products is sodium hypochlorite, and the most common one is 84 disinfectant. The active ingredient of the second generation disinfection products is p-chloro-m-xylenol (PCMX), and the common products are drip disinfectant and Verus disinfectant. The active ingredient of the third generation disinfection products is single and double chain compound quaternary ammonium salt (Qasafe Ji 'ankang), and the common product is Anjie full-effect bactericidal liquid; The active ingredient of the fourth generation disinfectant is guanidine. At present, there is only Bema Guardian in China. A simple evaluation of three generations of disinfection products can draw the following conclusions: the first generation of disinfection products: the disinfection and sterilization rate is very high, reaching the actual non-toxic standard (LD50 >；; 5000mg/kg), low cost, but strong corrosiveness. Disinfection products of the second generation: high disinfection rate and high cost, but slightly toxic (LD50=3800mg/kg) and slightly corrosive. Although the second generation disinfection products has no obvious harm to human body at normal concentration, there is no data to show whether it will accumulate in the body and cause potential chronic harm. The third generation disinfection products: the disinfection and sterilization rate is very high, reaching the actual non-toxic standard (LD50 >；; 5000mg/kg), non-corrosive, but bacterial pathogens are prone to drug resistance. Fourth-generation disinfection products: kill all kinds of bacteria, germs and microorganisms with high efficiency and broad spectrum, achieving food-grade safety, non-toxicity, stable performance, natural degradation without residue, physical sterilization and no drug resistance. I believe that understanding these basic knowledge will definitely help you choose disinfectant, and I wish you a healthy and safe life.

What kinds of disinfectants are there?
A. Oxidation: the sterilization mechanism is to release new ecological atomic oxygen and oxidize the active groups in bacteria; Sterilization is characterized by rapid and intense action, which can kill all microorganisms, including bacterial spores and viruses. Mainly surface disinfection, such as chlorine dioxide, hydrogen peroxide, ozone, etc. Such a disinfectant is a disinfectant. B, aldehydes: the sterilization mechanism is to denature or alkylate protein; The characteristic of sterilization is that it is effective for bacteria, spores, fungi and viruses. But the temperature has a great influence. Such as formaldehyde, glutaraldehyde, etc. This disinfectant can be used as a disinfectant. C. Phenols: the sterilization mechanism is to denature and precipitate protein or inactivate the enzyme system; The characteristic of sterilization is that it is effective for fungi and some viruses. D, alcohols: the sterilization mechanism is to denature protein and interfere with metabolism; Sterilization is effective for bacteria, but not for spores, fungi and viruses, such as ethanol and ethyl propanol. This disinfectant belongs to intermediate disinfectant and can only be used for general disinfection. E, alkali and salt: the sterilization mechanism is to denature, precipitate or dissolve protein; The characteristic of sterilization is that it can kill bacterial propagules, but it can't kill tiny spores, viruses and some microorganisms that are difficult to kill. Weak bactericidal effect and strong corrosiveness, such as nitric acid, caustic soda and salt. Can only be used as a general preventive disinfectant. F. Halogen: The sterilization mechanism is to oxidize the active genes in bacteria, and combine with amino groups to denature protein. It is characterized by killing most microorganisms, mainly surface disinfection, with unstable properties, and its sterilization effect is greatly influenced by environmental conditions, such as sodium hypochlorite, "84" disinfectant, excellent chlorine and so on. This disinfectant is an intermediate disinfectant and can be used as a general disinfectant. G, surfactant: sterilization mechanism is to change the permeability of cell membrane, make cytoplasm leak, hinder breathing or denature protease. The characteristic of sterilization is that it can kill bacterial propagules, but it has poor effect on spores, fungi, viruses and tuberculosis. It works well in alkaline and neutral conditions, such as bromogeramine and chlorpyrifos. This kind of disinfectant has low efficiency and can be used as a general disinfectant.
