Problems solved by technology

Judging from the current clinical situation, the cleaning solution is easy to form insoluble precipitates after long-term storage. After being used on the machine, crystals will form around the probe, and it will even block the probe and affect the amount of sample suction, resulting in unstable measurement results. Good for clinical testing
In addition, the validity period after opening the bottle is short, and the rapid decrease of available chlorine will weaken the stability of the cleaning solution and make the cleaning effect worse.

Embodiment 1

[0017] Accurately weigh 30g of sodium polyphosphate, 50g of sodium carbonate, and 5g of sodium lauryl sulfate, and fully dissolve them in deionized water in turn, so that the final system is 1L. Add it to the pre-prepared sodium hypochlorite cleaning solution at a mass volume ratio of 1%, and mark it as liquid A.

Embodiment 2

[0019] Accurately weigh 50 g of sodium silicate, 40 g of benzoic acid, and 5 g of fatty alcohol polyoxyethylene ether, and fully dissolve them in deionized water in sequence, so that the final system is 1 L. Add it to the pre-prepared sodium hypochlorite cleaning solution at a mass volume ratio of 1%, and mark it as B solution.

Embodiment 3

[0021] Accurately weigh 50 g of sodium silicate, 40 g of sulfamic acid, and 5 g of alkyl glycosides, and dissolve them in deionized water in turn, so that the final system is 1 L. Add it to the pre-prepared sodium hypochlorite cleaning solution at a mass volume ratio of 1%, and mark it as solution C.

Abstract

The invention discloses a biochemical analyzer cleaning fluid compound stabilizer which comprises disodium hydrogen phosphate, ethylenediamine tetraethyl diacid, lauryl sodium sulfate and alkyl glycoside. By the aid of the mode, the compound stabilizer is added into cleaning fluid taking sodium hypochlorite as a main component, preservation time of available chlorine in the cleaning fluid can be prolonged, stability is obviously improved, and good cleaning performance is ensured. The compound stabilizer is low in cost and simple to prepare and has wide practical significance, and sources are easily acquired.

Description

technical field [0001] The invention relates to the field of stabilizing agent research, in particular to a compound stabilizing agent for a cleaning solution for a biochemical analyzer. Background technique [0002] A biochemical analyzer is an instrument that measures a specific chemical composition in body fluids based on the principle of photoelectric colorimetry. Because of its fast measurement speed, high accuracy, and small consumption of reagents, it has been widely used in hospitals at all levels, epidemic prevention stations, and family planning service stations. Cleaning solution is one of the most commonly used reagents in biochemical analyzers. Among them, the cleaning solution with sodium hypochlorite as the main component is used to clean the blood and fibrin in the pipes or counting pools and probes to ensure the accuracy of the test results, and the consumption is huge. Judging from the current clinical situation, the cleaning solution is easy to form inso...
