Problems solved by technology

However, at present, the sources of cleaning solutions used in clinical laboratories mainly rely on imports, but the cost of imported reagents is high, which increases the cost of testing and indirectly increases medical costs; the actual use of domestic cleaning solutions is not good, especially for latex-enhanced For the detection items of the immunoturbidimetric transmission method (i.e. PETIA latex enhanced immune transmission turbidimetric method), since the latex contained in the reagent is a high molecular polymer, its main component is polystyrene, which is easy to adhere to the colorimetric On the cup, especially the polypropylene material cuvette, if the situation is serious, a layer of milky white adhesion will be formed on the inner surface of the cuvette, which will affect the light transmission of the cuvette, and then affect the absorbance reading , resulting in inaccurate test results
[0006] In addition, some domestic cleaning agents one-sidedly pursue the cleaning effect, and even add too much surfactant components or strong acid / alkali to improve the cleaning effect, so that the cleaning agent has a large damage load on the flow system of the instrument. There are many cases of crystallization and foaming, and some cases of carryover pollution caused by cleaning agents, so many products still cannot meet the needs of users

Abstract

The invention discloses cleanout fluid. The cleanout fluid provided by the invention comprises basic hydroxide, a nonionic surfactant, polyoxyethylene sorbitan monolaurate, a zwitterionic surfactant,ethylene diamine tetraacetic acid disodium, sodium citrate, trishydroxymethyl aminomethane, triclosan and an antifoaming agent. The cleanout fluid provided by the invention has an excellent cleaning effect, particularly has an excellent cleaning effect aiming at cleaning of latex reagents. Moreover, the antibacterial effect of appliances cleaned by the cleanout fluid provided by the invention is excellent, the cleanout fluid is not easily crystallized and is difficult to blister during use, the various biochemical substances can be effectively cleaned, and the cleanout fluid is very suitable for a reaction cup of a full-automatic biochemical analyzer.

Description

technical field [0001] The invention relates to a cleaning solution, in particular to a cleaning solution for cleaning analytical instruments. Background technique [0002] The automatic biochemical analyzer is an instrument for measuring a specific chemical composition in body fluids based on the principle of photoelectric colorimetry. The body fluids include serum, plasma, urine, cerebrospinal fluid, etc. Due to its high accuracy, high precision, and high flexibility It is characterized by high efficiency and high efficiency, and undertakes a lot of work in clinical laboratories. It is one of the most widely used instruments in clinical laboratories. [0003] When using a fully automatic biochemical analyzer for clinical laboratories, on the one hand, there are many types of items to be tested, and the corresponding in vitro diagnostic reagents have complex components; , therefore, cuvettes, pipes, etc. may be polluted by fibrin, crystals, oils, dyes, etc. to breed bacter...
