How to properly preserve medical disinfectant or 95% medical alcohol
Doubt: If there is a problem with the locker next to the wardrobe, how to properly store medical disinfectant or 95% medical alcohol? How can this thing be kept so that no chemical reaction will occur?
After using medical disinfectant for so long, do you know how long the real validity period is? Many friends may have such questions. They don't know how to store used medical disinfectants, such as 95% medical alcohol. They are afraid that this placement will be flammable or volatile. Guangxi Medical Supplies
Let's first analyze: medical alcohol itself is flammable and explosive. When the summer is hot, if you encounter high temperature, there will be the danger of its own explosion, which is not safe, so it should be placed in a dark place, which will not cause inflammable and explosive, and should be cool and ventilated. Comments: In addition, if I take it to the car, I cannot take it. In my car is the same as above, good bottles are not easy to break. Store small amounts. Store unused at warm.
In fact, after medical alcohol is opened, there is a valid period of use. Pour out the used iodine, 500m | 95% alcohol and 500ml iodophor. The validity period is 1 month, and the sterile container is immersed in the used disinfectant solution. Effective for 7 days after opening. Unopened disinfectants are generally valid for 2 years.
For disinfectants with unstable performance, such as chlorine-containing disinfectants, the use time after preparation should not exceed 24 hours.
Disinfection mechanism of medical alcohol
To denature proteins, it is necessary to stretch and relax the long chains of coiled and helical protein molecules, and the key is to break the forces that form the coils and spirals. Medical alcohol molecules have two ends, one end is hydrophobic (one is C2H5), which can destroy the attraction between hydrophobic groups inside the protein; one end is hydrophilic (a hydroxyl group), but it is difficult to destroy the hydrophilicity outside the protein. The attraction between the water groups.
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 proteins in bacteria. Only medical alcohol and water coexist, relax the various attractive forces that maintain the geometry of the protein, the protein will lose its physiological activity.
Therefore, only a certain concentration of medical alcohol solution can achieve good disinfection and sterilization purposes. Guangxi Medical Equipment Company
