Problems solved by technology

The common method used in the past was to use concentrated cleaning solution to concentrate and soak the blood cell counter when there was a plugging alarm. Although this operation method can solve the problem, this method is laborious and time-consuming, and it pollutes the environment and operators. The analyzer is highly corrosive

Abstract

A blood cell analyzer cleaning fluid is characterized in that one litre of cleaning fluid is provided with 10.0-4.0g of sodium chloride, 0-6.0g of sodium sulfate, 16.0-23.0g of plant prolease, 0.4-1.2g of complex enzyme stabilizer, 0.17-0.2g of sodium hypochlorite, 2.0-6.0g of anionic surfactant, a phosphate buffer toning the ph value to 8.0-9.0, and the balance is water, wherein, the adding amounts of sodium chloride and sodium sulfate are complementary, the sum of the two adding amounts is no more than 10g. The invention does not contain cyanide, azide, and has non-toxicity, which can effective improve working atmosphere of operating staff, and can reduce harm of toxicant to personal health; the physical chemistry characters of the reagent are stable, and the reagent can be stored in the room temperature for more than one year. The invention can not only secure testing result accuracy, but also can secure non-corrosiveness to the blood cell analyzer; and hs no pollution to the environment.

Description

technical field [0001] The invention belongs to cleaning reagents for medical diagnostic instruments, in particular to cleaning reagents only for blood cell analysis. Background technique [0002] Cleaning solution is one of the most commonly used reagents in hematology analyzers. Its function is to clean blood and fibrin in the pipeline to ensure the accuracy of test results. Take blood cell analysis as an example: After the blood is diluted with diluent, it is sampled into the red blood cell and white blood cell counting pool through the sampling needle, and the instrument will automatically add hemolytic agent. After a certain period of time, the instrument will automatically count. Automatically absorb a certain amount of cleaning solution to flush the pipeline, counting pool and channels through which the blood passes. Repeat the above steps to ensure the accuracy of the quality inspection results. The common method used in the past is: when there is a plugging alarm,...
