Cleanout fluid applicable to cleaning of clinical laboratory instruments and preparation method

Abstract

The invention discloses cleanout fluid applicable to cleaning of clinical laboratory instruments. The cleanout fluid is composed of, by mass, 81-90% of water, 2-4% of a surface active agent, 2-5% of an inorganic auxiliary agent, 1-2% of a solubilizing agent, 1-2% of lubrication rust inhibitor, 0.5-1% of a sterilizing agent and 2-5% of a green chelating agent. The preparation method of the cleanout fluid includes the steps that firstly, pure water is added into a container, then the surface active agent, the inorganic auxiliary agent, the solubilizing agent, the lubrication rust inhibitor, the sterilizing agent and the green chelating agent are sequentially added, the mixture is mixed and stirred to be uniform, and the cleanout fluid is obtained. According to the cleanout fluid, due to the fact that the added iminodisuccinic acid is a brand-new green chelating agent, the cleanout fluid has biodegradability and is safe and environmentally friendly; due to the fact that a compounded mixed surfactant system of the surface active agent sodium dodecyl benzene sulfonate, the inorganic auxiliary agent and the solubilizing agent is added, the cleanout fluid has good oil stain removal capacity and is low in foam output and easy to clean; due to the fact that rust prevention brightener methyl silicone oil is added, the cleanout fluid achieves rust prevention, maintenance and brightening effects on the instruments.

Description

technical field [0001] The invention relates to the technical field of medical detergents, in particular to a cleaning solution suitable for cleaning laboratory instruments and a preparation method thereof. Background technique [0002] Medical instruments in the laboratory are easily contaminated by blood, pus, protein, fat, etc. during use. After use, the instruments must be cleaned or other surface treatment before subsequent disinfection and sterilization. Traditional acidic or neutral cleaning agents are significantly less effective at removing pollutants than alkaline cleaning agents. However, due to the high pH value and strong alkalinity of alkaline cleaning agents, they are more harmful and corrosive to equipment, and the chelating agents used in traditional alkaline cleaning solutions are mostly NTA, EDTA, STPP, etc. Poor degradability, and can lead to pollution problems such as eutrophication of rivers. At the same time, the traditional alkaline cleaning agent a...

Problems solved by technology

Traditional acidic or neutral cleaning agents are significantly less effective than alkaline cleaning agents in removing pollutants, etc.

However, due to the high pH value and strong alkalinity of alkaline cleaning agents, they are more harmful and corrosive to equipment, and the chelating agents used in traditional alkaline cleaning solutions are mostly NTA, EDTA, STPP, etc. Poor degradability, and can lead to pollution problems such as eutrophication of rivers

At the same time, the traditional alkaline cleaning agent also has the disadvantages of not being able to have good compatibility with the cleaned instruments and cleaning machines and unable to protect the instruments from rusting.
