Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical diagnostic instrument reagents, and in particular relates to a linear wide-range blood cell analyzer reagent and a preparation method thereof. Background Art
[0002] Blood analysis is an indispensable part of modern medical diagnosis and is widely used in clinical diagnosis, disease monitoring and health examinations. As an important blood analysis tool, the hemocytometer can quickly and accurately detect various cell components in the blood, such as red blood cells, white blood cells and platelets. However, existing hemocytometer reagents have certain limitations in terms of detection range and accuracy.
[0003] The preparation process of existing blood cell analyzer reagents is complicated, which is not conducive to large-scale production and application. In addition, some reagents are imported reagents, which not only have a long cycle but also are expensive. At the same time, many existing blood cell analyzer reagents can only cover a limited detection range and cannot meet the clinical needs for a wide range of blood parameters. For example, some reagents may have errors or fail to detect when detecting low-concentration or high-concentration blood samples. In addition, traditional reagents are easily affected by environmental factors during storage and use, resulting in unstable test results.
[0004] Chinese patent CN 104698157 B relates to a reagent for a blood cell analyzer, which consists of a diluent, an EOI hemolytic agent, an LH hemolytic agent, an EOII staining solution, and a cleaning solution. This reagent has a wide range of uses, is applicable to many models, and has accurate test results. The correlation coefficient R value after linear regression with the original blood cell reagent reaches more than 0.99, which reflects a good correlation. In addition, the raw materials of the reagent are non-toxic and harmless, which is conducive to the promotion and application of the reagent for the blood cell analyzer. However, this reagent does not involve the study of anticoagulability, while anticoagulants not only involve the processing and preservation of samples after blood collection, but their selection is also crucial for the counting and classification of blood cells.
[0005] Therefore, there is an urgent need to develop a linear wide range hemacytometer reagent to make the reagent test results stable and accurate. Summary of the invention
[0006] In view of the existing technical problems, the object of the present invention is to provide a linear wide range blood cell meter reagent and a preparation method thereof, wherein the blood cell meter reagent is composed of a diluent, a hemolytic agent, a dye and a cleaning solution. The blood cell meter reagent of the present invention has excellent anticoagulant properties, can provide accurate test results within a wider detection range, and has better stability and economy, and has high application and market value.
[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:
[0008] In one aspect, the present invention provides a linear wide range hematology analyzer reagent, which is composed of a diluent, a hemolytic agent, a dye and a cleaning solution; wherein:
[0009] The components and contents of the diluent are: osmotic pressure regulator 5-8 g / L, buffer 1-2 g / L, anticoagulant 0.3-0.6 g / L, preservative 0.2-0.4 g / L;
[0010] The components and contents of the hemolytic agent are: osmotic pressure regulator 1.6-2.4 g / L, quaternary ammonium surfactant 2.8-4.2 g / L, nonionic surfactant 4-6.5 g / L, stabilizer 1.6-2.4 g / L, EDTAK 20.1-0.3 g / L, Triton X-100 1-1.5 g / L, 4-hydroxyethylpiperazineethanesulfonic acid 3-6 g / L, succinic acid 0.6-1 g / L;
[0011] The components and contents of the dye are: polymethine dye 0.015-0.035 g / L, methanol 25-35 g / L, ethylene glycol 900-1000 g / L;
[0012] The components and contents of the cleaning solution are: 5-10 g / L of osmotic pressure regulator, 2-4.5 g / L of nonylphenol polyoxyethylene ether, 1-2.5 g / L of buffer, 0.1-0.3 g / L of preservative, and 6-12 g / L of complex enzyme.
[0013] The reaction mechanism and effects of the present invention are as follows:
[0014] 1. Biomedical materials need to have good biocompatibility due to their special applications, which is the key to whether the material can be used as a blood-contact medical material. The present invention synthesizes an anticoagulant with a hyperbranched structure. Through molecular design and synthesis, a hyperbranched material with good anticoagulant performance is prepared, which can broaden its application in the field of biomedical materials.
[0015] After modification, the anticoagulant synthesized by the present invention has an electrostatic repulsion effect between its surface and blood components, and has good anticoagulant properties. The present application selects 2,2-diisopentyl-1,3-propanediol and 2-hydroxy-4-pentenoic acid as monomers to synthesize branched structures, but its solubility is poor, which may be due to the intermolecular hydrogen bonds formed by ester groups and hydroxyl groups and the presence of unsaturated double bonds. The applicant introduces a carboxylic acid group through 2-chloropropionic acid to improve the blood compatibility of the substance, because the carboxylic acid group not only makes the surface of the material have a certain negative charge, but also destroys the presence of unsaturated double bonds. Further, 1,3-propane sultone is introduced, and the sulfonic acid group in its structure has good water solubility, which will destroy the hydrogen bonding between hydroxyl groups, thereby improving the solubility of hyperbranched substances, giving full play to their excellent anticoagulant properties, and also providing more possibilities for the application of hyperbranched substances in the field of biomedicine.
[0016] 2. The present invention introduces a thiol group by adding 2-phenylethanethiol to the molecular skeleton of benzothiazole to synthesize a thiol ester stabilizer of benzo heterocycle. On the one hand, the novel stabilizer structure reduces the rigid structure of phenylbenzothiazole by utilizing the lone pair of electrons of the sulfur atom, making the molecular structure more flexible, enhancing the ultraviolet absorption intensity, and improving the stability. On the other hand, the complex formed by the cationic surfactant and hemoglobin can be made to keep the absorbance value of a specific wavelength unchanged within the instrument detection time by the stabilizer, significantly improving the accuracy and stability of the hemoglobin concentration determination.
