What does medical alcohol do? What is medical alcohol used for?

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.

Here's how:1.If you buy alcohol with a concentration of 90%, dilute it according to the instructions before use.

2.A 75% alcohol swab or alcohol can not only kill the virus, but also be cheap.

3.Wipe down doorknobs, tabletops, elevator buttons, etc., without spraying heavily in the air or on the body.

4.It is not recommended to spray and disinfect clothing with alcohol, as burning may occur in the event of an open flame or static electricity.

5.The use of alcohol indoors needs to be ventilated, kept away from hot objects, and never come into contact with open flames.

6.Behaviors such as smoking, smoking, and using electric mosquito swatters cannot be carried out immediately after spraying high-concentration alcohol.

7.Clean up the surrounding flammable and combustible materials before use, and turn off the power before disinfecting the surface of the electrical appliance.

8.Used towels and other cleaning tools should be washed with clean water and left to dry in a ventilated place.

1. For disinfection: medical alcohol can be used to disinfect ** or the surface of objects to prevent the breeding of bacteria.

2. For cleaning: Medical alcohol can clean fingers or surfaces to remove bacteria and dirt.

3. For drug preparation: medical alcohol can be used to prepare solutions, suspension agents and other pharmaceutical preparations.

4. Used for disinfection surgery: medical alcohol can be used to sterilize surgical instruments to ensure the safety of surgical operations.

Medical alcohol is mainly used in the field of sterilization and antivirus. Due to the special principle of alcohol disinfection, only 75% alcohol can be sterilized and disinfected, and medical alcohol can kill more than 90% of bacteria and viruses. Medical alcohol also has the effect of cleaning**, and the medical alcohol can be diluted and rubbed on the patient's back to prevent the symptoms of bedsores.

The role of medical alcohol is mainly used for sterilization and sterilization, and medical alcohol is especially used in hospitals, because the use of alcohol in medical spine can kill more than 90% of bacteria and viruses. The common bacteria that medical alcohol can kill are Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, hemolytic streptococcus and so on.

At present, only medical alcohol can have the effect of sterilization and disinfection, because only 75% concentration of alcohol can enter the bacteria, and by coagulating the protein in the bacteria to denature the protein, the bacteria that lose the enzyme will slow down the reproduction, after a period of time, in the end, it can completely kill the germs.

Medical alcohol also has the effect of cleaning, because the alcohol used by medical and wild rolls can be disinfected and sterilized, and it is not toxic, so it is mostly used for disinfection and cleaning. After diluting the medical alcohol to about 40 degrees, you can also wipe the back of the bedridden patient, which can prevent the patient from getting bedsores to a certain extent.

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.

1. Medical alcohol is more than 75%, with the effect of disinfection and sterilization, the main component is ethanol, the main mechanism of action is to denature the intracellular protein, only when alcohol and water coexist, the geometric shape of the cell protein can be deformed, the attraction is reduced, and it is inactive, so only a certain concentration of alcohol can be sterilized.

2. Different concentrations of alcohol have different effects, 95% can be wiped and disinfected, 75% can be cleaned and disinfected, 45% can be used to treat bedsores, and 25% and 35% can be physically cooled.

1. Alcohol can be used for the disinfection of medical equipment, wipe with sterile absorbent cotton balls dipped in alcohol, and then ventilate and dry, 2. The disinfection of seat armrests in public places can be sprayed with a watering can, and the alcohol can penetrate into the bacterial body to coagulate the protein in the bacterial body, so as to achieve the purpose of killing bacteria.

3. The ** that is often used in life, mobile phones, and handrails in public places can be wiped with alcohol.

4. There is also a thermometer used, which should be wiped and disinfected with 75% alcohol after use.

5. When you go out and don't have water to wash your hands, you can also spray a little alcohol on your hands, which can play a role in sterilization.
