What is Medical Alcohol? What is Medical Alcohol?

The medical alcohol concentration of 75% is used for disinfection and debridement before surgery. The concentration of 95% is used for the disinfection of medical equipment.

The composition of medical alcohol is mainly ethanol, with two concentrations of 75% and 95%, and the use of alcohol in these two concentrations is different. Medical alcohol use is widespread, but less than 30% of households use alcohol correctlyIncorrect alcohol concentration not only makes it difficult to achieve the desired effect, but it can also cause harm to the body.

75% alcohol can be used for disinfection and disinfection of thermometers, such as before injection or around wounds. 95% of alcohol cannot be used directly on patients, and is commonly used in hospitals to wipe ultraviolet lamps, while homes can only be used to clean camera lenses, etc.

Many people have a similar misconception that the higher the concentration, the better the disinfection effect should be, but this is not the case. Too high a concentration of alcohol will form a protective film on the surface of the bacteria, which will prevent the alcohol from entering the bacteria, and it is difficult to completely kill the bacteria.

Conversely, it is not okay to have too low an alcohol concentration. Alcohol with too low a concentration can enter the bacteria, but it cannot coagulate the proteins in the body, nor can it kill the bacteria. It has been scientifically confirmed that the alcohol that disinfects best is 75% of the alcohol.

Alcohol mixed with water, it seems to be 9%.

I see you've got medical alcohol in your head?

The main ingredient of medical alcohol is ethanol, which is a plant raw material product, which is made by saccharification and refermentation of starch plants and distillation, which is equivalent to the process of making liquor. However, the distillation temperature of medical alcohol is lower than that of wine, the number of distillations is more than that of wine, the alcohol content is high, the output of finished products is high, and the ether and aldehyde components other than alcohol are more than wine, so they cannot be drunk. Medical alcohol can come into contact with the human body and is often used to scrub wounds.

Chinese name medical alcohol.

Also known as ethanol. Chemical formula: C2H5OH molecular weight.

The boiling point is low, and the water solubility is miscible with water in any proportion.

The appearance is colorless and transparent.

Uses: It is often used to scrub wounds.

Concentrations 75% and 95%.

Collapse Use. In daily life, it is common for some people to use medical alcohol to scrub wounds to achieve the purpose of sterilization and disinfection. It is worth noting that the alcohol available in pharmacies has two concentrations, 75% and 95%, and the two concentrations of alcohol are not used for the same purpose.

Disinfection mechanism. Medical alcohol.

To denature proteins, it is necessary to stretch and relax the long chains of protein molecules that are curled and helixed, and the key is to destroy the various forces that form curls and helixes. The alcohol molecule has two ends, one end is hydrophobic (a c2h5), which can destroy the attraction between hydrophobic groups inside the protein; One end is hydrophilic (OH), but it is difficult to break the force of attraction between hydrophilic groups on the outside of the protein. On the other hand.

Although the water molecule can relax the attraction between the hydrophilic groups of the protein, it cannot destroy the attraction between the hydrophilic groups in its protein even if it burrows inside the bacteria. Therefore, neither pure alcohol nor water is sufficient to denature the protein within the bacteria, and the protein will lose its physiological activity only if alcohol and water coexist while relaxing the various attractions that maintain the geometry of the protein. Therefore, only a certain concentration of alcohol solution can achieve a good disinfection and sterilization purpose.

Different concentrations. The concentrations below are all referred to as volume fractions).

95% alcohol is commonly used to wipe UV lamps. This alcohol is commonly used in hospitals, but in the home it is only used for the cleaning of camera lenses.

75% alcohol is used for disinfection. This is because too much 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 it cannot coagulate the proteins in the body, and it cannot completely kill the bacteria.

40% to 50% alcohol prevents pressure sores. For example, a little 40% of 50% alcohol is poured into the hands during massage, and the patient's pressure part is massaged evenly, which can promote local blood circulation and prevent the formation of pressure sores.

It is medical alcohol, and medical alcohol is alcohol with a relatively high concentration and suitable for medical use.

Medical alcohol is specially used for disinfection, which is about 5% concentration.

Medical alcohol refers to the alcohol used in medicine, the common purity is 95% and 75%, and it is mainly used for disinfection and sterilization.

Medical alcohol belongs to 75% concentration of alcohol, mainly because only 75% concentration of alcohol, can enter the bacteria to kill bacteria, if the concentration is too high or too low can not meet the sterilization requirements. Medical alcohol is widely used in the disinfection of medical devices, and it is necessary to tighten the cap and store it in a cool place when using.

Medical alcohol is also called 75% alcohol, mainly because the concentration of medical alcohol is usually 75%. Due to the sterilization particularity of alcohol, alcohol can only be effectively sterilized when the concentration is about 75%, so if the concentration of alcohol is too high or too low, it cannot meet the requirements of medical sterilization and disinfection.

A concentration of 75% alcohol can enter the inside of the cell and cause protein denaturation by coagulating the proteins inside the cell, so that the bacteria lose the energy provided by the enzymes, so as to achieve the purpose of sterilization and disinfection. Alcohol can destroy more than 90% of bacteria and viruses, including Candida albicans, Escherichia coli, Pseudomonas aeruginosa, etc.

Medical alcohol is widely used in the disinfection of medical devices, and because it is non-toxic, the general public can also buy it in pharmacies for home use. When using medical alcohol, it is necessary to pay attention to the fact that medical alcohol is flammable and volatile, so it is necessary to tighten the cap after use and store it in a cool place.

If the approval procedures have been completed in accordance with the law when dealing in medical alcohol, it is not considered a crime; If it is operated without going through the relevant procedures, it is considered a crime. If the market order is disrupted, and the circumstances are serious, it will also constitute the crime of illegal business operation.
