Cleaning fluid

Abstract

The invention discloses cleaning fluid which comprises an anionic surfactant, a non-ionic surfactant, an alkali metal hydroxide, plantrennet and a buffer agent for stabilizing the pH value to be greater than 12.0. When being used, the cleaning fluid disclosed by the invention has the characteristics of low protein substance residue rate, low fat substance residue rate, good in-batch repeatability of clinical projects, low cross contamination, low reactant deposition and the like, and meanwhile the testing result of a biochemical analyzer is not affected; a liquid path system and a reaction cup of the biochemical analyzer are not corroded in the washing process; meanwhile, all components of the cleaning fluid disclosed by the invention can be biologically degraded, no potential pollution to the environment is caused, and the requirements of environmental protection are met.

Description

[0001] technical field [0002] The invention relates to a cleaning solution, in particular to a cleaning solution used in conjunction with an automatic biochemical analyzer. Background technique [0003] At present, manufacturers of automatic biochemical analyzers provide matching cleaning solutions according to the design of the instruments to meet the daily maintenance of the instruments and ensure the accuracy of sample testing. However, different cleaning solutions have different cleaning effects. For example, some cleaning solutions are acidic and alkaline cleaning solutions, and some are alkaline cleaning solutions. Most of the special cleaning solutions for biochemical analyzers on the market are alkaline cleaning solutions. Whether the alkaline cleaning solution is used alone, or the acidic and alkaline cleaning solutions are used in combination, it is necessary to ensure that the cleaning effect can fully meet the needs of clinical tests while maintaining good com...

Problems solved by technology

When these cleaning solutions are used, they all have their own special requirements. Some require corresponding washing temperatures, some require extremely strong oxidants, some require a relatively long time for washing, and some cleaning solutions need to add washing enzymes and bleaching agents. , fluorescent agent, etc. These special requirements make these cleaning solutions not suitable for automatic biochemical analyzers. If they are used forcibly, some parts of the instrument may be damaged, and it may also cause inaccurate test indicators, misdiagnosis, etc. Serious outcome, life threatening to patient

At the same time, most cleaning solutions contain potential environmental pollutants such as chlorine and phosphorus, which is not conducive to environmental protection and is banned in many countries.

[0006] At present, the acidic or alkaline cleaning solutions provided by biochemical analyzer suppliers are only matched with their respective instruments. When used for cleaning biochemical analyzers from other manufacturers, they may be incompatible with the instrument and cause corrosion to the instrument.

In the cleaning process, if acidic and alkaline cleaning solutions are used to clean in sequence, it has a lower residual rate of protein substances, residual lipid substances, low cross-contamination, low reaction product deposition, etc., but it will increase the cost of testing

However, if it is cleaned with an acidic or alkaline cleaning solution, although the production cost is reduced, the cleaning of some test indicators cannot meet the test requirements, resulting in a wrong diagnosis in clinical practice, and there is an adverse risk in application.
