Overview
Alcohol cotton balls are made from sterilized absorbent cotton balls absorbing medical alcohol, which can disinfect human skin and prevent infection. After repeated experiments, people know that 75% alcohol has the strongest bactericidal power, so medical disinfection alcohol generally contains 75% pure alcohol and 25% water. The concentration of alcohol is very important. If it is too high or too low, it will weaken or even lose its disinfection performance. Therefore, measures must be taken to keep the concentration unchanged. Alcohol is volatile and causes a decrease in concentration, so it should be stored in a fairly airtight container. This is often the case: the top of the cotton balls in the container are all dry, only some of the cotton balls below are still a little wet. Some people think that the wet part is alcohol. In fact, this is almost all water, so it can no longer be used for disinfection.
In daily life, it is inevitable that there will be some minor wounds on the skin surface. People usually think of band-aids. "The band-aid cannot be regarded as a panacea. The band-aid itself has no anti-inflammatory effect." A surgeon at Xinqiao Hospital of the Third Military Medical University reminded that the role of the band-aid is to absorb exudate and keep the wound dry. After the trauma, the wound of the patient should be disinfected before using the band-aid to prevent infection. The common disinfectant alcohol cotton balls on the market are packaged in a portable and independent package, and are divided into two types of packaging: external tweezers and internal tweezers. External tweezers, that is, the tweezers and the alcohol cotton ball are placed separately. The tweezers may be contaminated when exposed to the air after use. The tweezers attached to the alcohol cotton ball packaging bottle can keep the tweezers in a sterile state and avoid contamination. For example, Ianting alcohol cotton balls have the advantages of safety and reliability, no residue after use, and convenient carrying and use. It is a must for modern families to disinfect and travel. Spare supplies.
Alcohol concentration
Clinical trials show that 75% alcohol has the strongest bactericidal power and is also the most scientific medical disinfection alcohol ratio. Too low alcohol concentration will weaken or even lose the effectiveness of sterilization. The same is true for too high alcohol concentration. This is because too high alcohol concentration will denature the protein immediately after the alcohol penetrates into the bacteria. The denatured protein forms a protective film in the bacterial cell membrane, preventing the alcohol from reaching deeper levels.
Scope of application
Preschool children-prevention of hand, foot and mouth
Diabetic patients-avoid infection
The general population-can not be Band-aid is regarded as a panacea, and the band-aid itself has no anti-inflammatory effect. The role of band-aid is to absorb exudate and keep the wound dry. After a traumatic injury, the patient's wound should be disinfected before using the band-aid to prevent infection.
Preservation
Alcohol is very volatile. If you want to keep the concentration of the alcohol cotton ball unchanged, store it in a fairly airtight container. In daily life, you can buy portable independent packaging, not only for carrying, but also for better storage. Commonly available in the market are divided into two types of packaging: external tweezers and internal tweezers. The internal tweezers are placed in the alcohol cotton ball packaging to effectively avoid secondary pollution during use.
After packaging, store in a clean room with a relative humidity of no more than 80%, in a cool, dry, ventilated, and non-corrosive atmosphere. During transportation, it should be protected from moisture, light, and away from heat sources.
Role
First, prevent the spread of hand, foot and mouth daily
Refer to newspaper for specific literature and information of hand, foot and mouth
Second, prevent infection by diabetes Importance of
1. Because diabetes patients have high blood sugar levels, poor control will weaken their ability to fight infections, so they are prone to infections.
2. People with neuropathy become insensitive to pressure, temperature, pain, etc., and can easily cause injury.
3. People with vascular disease, due to insufficient blood supply to various parts of the body, the wounds heal slowly, and eventually lead to ulcers, infections or even badness, and even amputation is needed to solve the problem.
Therefore, the families of diabetic patients need alcohol cotton balls, because only using alcohol to kill drugs will cause secondary pollution.
3. Physical cooling with alcohol cotton ball
The easiest, effective and safe way to cool children with high fever is to use 25%-50% alcohol to rub the bath. Soak the child with a small towel and wipe the neck, limbs, back, hands, feet, and other parts of the child. Especially focus on areas with abundant blood vessels, such as the underarms, elbows, fossa, and groin. Note that alcohol baths should not be used for measles and other eruptive diseases. When scrubbing the skin of patients with alcohol, it can not only stimulate the expansion of blood vessels in the skin of patients with high fever, and increase the heat dissipation capacity of the skin; but also because of its volatility, it can absorb and take away a large amount of heat, lowering body temperature and alleviating symptoms. Need to pay attention to several items l During the use of alcohol, avoid secondary pollution caused by tweezers, cotton balls, towels, etc.
The ratio of alcohol concentration must be scientific and reasonable in order to be effective
It is not advisable to use alcohol baths for measles and other eruptive diseases.
Fever 38.5 or have Children with a history of convulsions should use antipyretics in time
Experts’ reminder:
In daily life, please do not overuse alcohol cotton balls! Alcohol mainly targets general bacteria, and has certain limitations in terms of use effect and action time, so do not blindly exaggerate the effect of alcohol in sterilization. For example, for the cleaning of toys, you must use a chlorine-containing 84 disinfectant. Simply wiping with an alcohol cotton ball will not have any effect; for the cleaning of dishes and chopsticks, high-temperature boiling is more effective.
