Problems solved by technology

During the normal use of the automatic urine analyzer, there are steps such as strip selection, sample dropping, pipeline flushing, and detection. The main function of the ordinary cleaning solution used in flushing the pipeline is to clean the sampling needle and avoid crossover between samples. Pollution, but not enough to clean and maintain the entire fluid system of the urine analyzer, so that the urine analyzer is prone to problems such as urine scale deposition and pipeline blockage during use, which will affect the normal test

Embodiment 1

[0023] A cleaning solution for a urine analyzer, the cleaning solution comprises the following components in terms of mass percentage: 0.17% of a surfactant (fatty alcohol polyoxyethylene ether), 0.875% of an oxidizing agent (hydrogen peroxide), a stabilizer (0.08% coke Sodium phosphate and 0.25% sodium carbonate) 0.33%, water 8%, and the balance is a buffer solution (pH is 8.5 Tris-hydrochloric acid buffer, prepared by mixing Tris solution and hydrochloric acid solution with a concentration of 0.05mol / L). This cleaning solution is made by the following method:

[0024] Dissolve stabilizer (0.8g sodium pyrophosphate and 2.5g sodium carbonate) in 80g water and add 25g oxidizing agent (mass fraction is 35% hydrogen peroxide), after the oxidizing agent is mixed, add surfactant (1.7g fatty alcohol poly Oxyethylene ether), after mixing, add buffer solution (Tris-hydrochloric acid buffer solution with a pH of 8.5, prepared by mixing Tris solution and hydrochloric acid solution with ...

Embodiment 2

[0026] A cleaning solution for a urine analyzer, which comprises the following components in terms of mass percentage: 0.21% of a surfactant (alkylphenol polyoxyethylene ether), 1.4% of an oxidizing agent (sodium hypochlorite), a stabilizer (silicic acid) sodium) 0.05%, water 12%, and the balance is buffer solution (pH is the disodium hydrogen phosphate-sodium dihydrogen phosphate buffer solution of 11, which consists of disodium hydrogen phosphate solution and sodium dihydrogen phosphate with a concentration of 0.2mol / L solution mixed). This cleaning solution is made by the following method:

[0027] Dissolve the stabilizer (0.5g sodium silicate) in 120g water and add 14g oxidant (sodium hypochlorite). After the oxidant is mixed well, add surfactant (2.1g alkylphenol polyoxyethylene ether), mix well and add buffer solution (disodium hydrogen phosphate-sodium dihydrogen phosphate buffer solution with a pH of 11, prepared by mixing disodium hydrogen phosphate solution and sodi...

Embodiment 3

[0029] A kind of cleaning liquid for urine analyzer, by mass percentage, this cleaning liquid comprises following components: surfactant (sulfobetaine) 0.06%, oxidizing agent (calcium peroxide) 0.45%, stabilizer (0.005% tin Sodium acid and 0.12% organic phosphite) 0.125%, water 15%, the balance is buffer solution (pH is the barbital sodium-hydrochloric acid buffer solution of 9, by the barbital sodium solution that concentration is 0.04mol / L mixed with hydrochloric acid solution). This cleaning solution is made by the following method:

[0030] Dissolve the stabilizer (0.05g sodium stannate and 1.2g organic phosphite) in 150g water and add 4.5g oxidant (calcium peroxide), and then add surfactant (0.6g sulfobetaine ), after mixing, add buffer solution (pH is 9 barbital sodium-hydrochloric acid buffer solution, prepared by mixing barbital sodium solution and hydrochloric acid solution with a concentration of 0.04mol / L) until the total mass is 1kg, i.e. Can.

Description

technical field [0001] The invention belongs to the technical field of chemical disinfectants, and in particular relates to a cleaning solution for a urine analyzer and a preparation method thereof. Background technique [0002] Fully automatic urine analyzer is one of the most widely used instruments in clinical laboratories, with the characteristics of good accuracy, high precision, and fast detection speed. During the normal use of the automatic urine analyzer, there are steps such as strip selection, sample dropping, pipeline flushing, and detection. The main function of the ordinary cleaning solution used in flushing the pipeline is to clean the sampling needle and avoid crossover between samples. Pollution, but not enough to clean and maintain the entire fluid system of the urine analyzer, so that the urine analyzer is prone to problems such as urine scale deposition and pipeline blockage during use, which will affect the normal test. Therefore, there is an urgent nee...
