Problems solved by technology

These residual pollutants are easy to corrode the instruments. In addition, during the use of surgical instruments, there will also be abrasions and scratches. The high temperature and high humidity conditions during cleaning and sterilization will also easily cause the instruments to rust. If the quality of the cleaning water is not up to standard It will accelerate the rust and corrosion of instruments
If the instrument is corroded and rusted, it will make the instrument dull and the joints jerky, causing inconvenience to the user
And it is easy to breed bacteria in rust and rust spots, which may lead to subsequent sterilization failure and cause cross infection between patients. Therefore, it is very necessary to choose a suitable rust remover for rust removal
[0003] At present, the rust removers on the market often have the disadvantages of ineffective rust removal and long rust removal time during use.
Some rust removers volatilize some harmful substances during use, which endangers the safety of users, and some rust removers use inorganic strong acids because they pursue the rust removal effect too much, which causes great damage to equipment and equipment, and greatly shortens the life of equipment and equipment. service life

Abstract

The invention discloses a medical device rust removing agent. The medical device rust removing agent comprises, by mass percent, 5%-50% of organic acid, 5%-30% of a surface active agent, 5%-15% of a corrosion inhibitor, 5%-10% of a solvent, 1%-10% of a bactericide, 0.01%-1% of essence and the balance pure water, and the total amount is 100%. According to the medical device rust removing agent, the new corrosion inhibitor is used as a raw material for preparing the rust removing agent, the beneficial effects that efficient corrosion inhibition and scale inhibition and chelation are achieved, no toxin exists, and rinsing is easy are achieved, rust removing is conducted efficiently, and a device can also be effectively protected. The preparing method is simple, the performance is reliable, environment friendliness is achieved, no toxin, harm and pollution exist, and the medical device rust removing agent is ideal.

Description

technical field [0001] The invention relates to a rust remover for medical instruments and a preparation method thereof. Background technique [0002] After surgical instruments are used, organic pollutants such as blood stains and oily tissue fluids often remain on the surface. These residual pollutants are easy to corrode the instruments. In addition, during the use of surgical instruments, there will also be abrasions and scratches. The high temperature and high humidity conditions during cleaning and sterilization will also easily cause the instruments to rust. If the quality of the cleaning water is not up to standard It will also accelerate the rust and corrosion of instruments. If the instrument corrodes and rusts, it will make the instrument dull and the joints jerky, causing inconvenience to the user. And it is easy to breed bacteria in rust and rust spots, which may lead to subsequent sterilization failure and cause cross infection between patients. Therefore, it...
