Dropping wine into the ear to reduce inflammation

The ear is the most important part of our body, and the ear is divided into the ear canal and the tissues inside the ear, which is relatively complex. When the body is getting angry or is stimulated by the outside world, it will easily cause ear inflammation. Ear inflammation will easily affect hearing and cause pain. Alcohol can have an anti-inflammatory effect, but it cannot be dripped into the ear canal, as it will easily cause damage to the ear canal.

Can putting alcohol in the ear reduce inflammation?

Can't. Alcohol is used to kill bacteria and is not strictly an anti-inflammatory drug. Especially if there is a perforation of the eardrum, you should not use the drip. You can use a cotton swab dipped in clean water or hydrogen peroxide to clean the external auditory canal

Medical alcohol

The main component of medical alcohol is ethanol, and it is a mixture. Medical alcohol is made from starchy plants through saccharification, fermentation and distillation, which is equivalent to the process of making wine, but the distillation temperature is lower than that of wine, the number of distillations is more than that of wine, the alcohol content is higher, the output of the finished product is high, and it contains more ether and aldehyde components other than alcohol than wine. It cannot be drunk, but can come into contact with the human body for medical purposes. It is a plant raw material product.

use

In daily life, it is common for some people to use medical alcohol to scrub wounds in order to achieve the purpose of sterilization and disinfection. It is worth noting that the alcohol purchased in pharmacies comes in two concentrations: 75% and 95%, and the uses of these two concentrations of alcohol are different.

Disinfection mechanism

To denature protein, the long chains of curled and helical protein molecules must be stretched and relaxed. The key is to destroy the various forces that form the curling and helical. The alcohol molecule has two ends, one end is hydrophobic (-C2H5), which can destroy the attraction between the hydrophobic groups inside the protein; the other end is hydrophilic (-OH), but it is difficult to destroy the attraction between the hydrophilic groups outside the protein. on the other hand. Although water molecules can relax the attraction between the hydrophilic groups of proteins, even if they penetrate into the bacteria, they cannot destroy the attraction between the hydrophobic groups in their proteins. Therefore, neither pure alcohol nor water is sufficient to denature the proteins in bacteria. Only when alcohol and water coexist and relax the various attractive forces that maintain the geometric shape of the proteins will the proteins lose their physiological activity. Therefore, only alcohol solutions with a certain concentration can achieve good disinfection and sterilization purposes.

Different concentrations

(The following concentrations refer to volume fractions)

95% alcohol is often used to wipe UV lamps. This type of alcohol is commonly used in hospitals, but at home it is only used to clean camera lenses.

75% alcohol is used for disinfection. This is because too high a concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, making it difficult to kill the bacteria completely. If the alcohol concentration is too low, it can enter the bacteria but cannot coagulate the protein in their bodies, nor can it completely kill the bacteria.

40% to 50% alcohol can prevent bedsores. The back, waist and buttocks of bedridden patients may develop bedsores due to long-term pressure. If you pour a little 40% to 50% alcohol into your hands and evenly massage the pressure areas of the patient, you can promote local blood circulation and prevent the formation of bedsores.

25% to 50% alcohol can be used to physically reduce fever. Patients with high fever can use it to rub their bodies to reduce temperature. Because wiping the skin with alcohol can dilate the patient's skin blood vessels and increase the skin's heat dissipation capacity. Its volatility can also absorb and take away a large amount of heat, thereby relieving symptoms. However, the alcohol concentration should not be too high, otherwise it may irritate the skin and cause the epidermis to lose a large amount of water.

Maintenance Application

Maintenance personnel often need to do some cleaning and maintenance work when repairing various household appliances, instruments, and electronic equipment. The medical disinfectant alcohol used in daily life is the best cleaning agent. It has the characteristics of strong decontamination effect and easy volatility. It can not only effectively remove various stains on the surface of electrical appliances, but also quickly clean the internal stains of some electronic components without affecting the performance of the appliances. The following introduces several simple methods for cleaning electrical appliances and electronic components.
