Embodiment 1

[0042] The cleaning solution includes the following components in mass percent of the cleaning solution:

[0043] Polyvinylpyrrolidone (its number average molecular weight is 20000) 0.2%;

[0044] Sodium dodecylbenzenesulfonate 0.1%;

[0045] Triton 100 0.05%;

[0046] NaClO 0.2%;

[0047] Proclin 300 0.02%.

[0048] The preparation process of cleaning solution includes:

[0049] 1) Prepare a buffer solution and weigh Na in a ratio of 1:1 according to the molar amount 2 HPO 4 12H 2 O and KH 2 PO 4 , so that the molar weight of phosphorus is 0.4M as the buffer mother solution, take 25mL of the above mother solution in a beaker, add 975mL deionized water to prepare a buffer solution with a concentration of 10mM;

[0050] 2) Weigh the polyvinylpyrrolidone, sodium dodecylbenzenesulfonate, Triton 100 and NaClO in the above mass percentages in turn, add them to the buffer solution obtained in step 1), stir well, and use NaOH to adjust the pH value to 12. Then add Proclin 3...

Abstract

The invention discloses a cleaning fluid and application thereof.The cleaning fluid comprises an anti-reprecipitation agent and an auxiliary surfactant, the anti-reprecipitation agent comprises a water-soluble high-molecular polymer containing strong polar groups, and the auxiliary surfactant comprises at least one of an anionic surfactant and a nonionic surfactant; the cleaning solution is used for cleaning the blood coagulation analyzer, the cleaning effect is better, and the cleaning solution has no influence on the detection result.

Description

technical field [0001] The invention relates to the technical field of medical inspection, and more specifically, to a cleaning solution and its application. Background technique [0002] The cleaning method of the automatic coagulation analyzer includes two cleaning solutions, one is a deep cleaning solution, which is used for deep cleaning of the sampling needle, and removes the residual sample on the inner wall of the needle and the sample suction point of the needle tip, so as to avoid the residual sample from causing damage to the next sample. Contamination, one is the regular cleaning solution, which is used to rinse the deep cleaning solution and restore the sampling needle to a clean state. Because the coagulation meter uses an anhydrous cleaning solution, the cleaning effect of the two cleaning solutions is very strict, and the cleaning solution is required to have no residue and will not affect the results of the measurement items. [0003] At present, the commerc...
