Automatic blood sample blending device and blood cell analysis device

Abstract

The invention discloses an automatic blood sample blending device and a blood cell analysis device. The automatic blood sample blending device comprises a first support, a second support and a flexible column, wherein the second support is fixedly connected above the first support through the flexible column and enables rotary swing and vibration relative to the first support. The part, between the first support and the second support, of the flexible column is arranged in an hourglass shape. The automatic blood sample blending device and the blood cell analysis equipment can automatically andfully blend trace samples without manual treatment, save labor and time cost, and improve the working efficiency of blending trace samples.

Description

technical field [0001] The invention belongs to the technical field of blood cell analysis, and more specifically, the invention relates to an automatic blood sample mixing device and blood cell analysis equipment. Background technique [0002] At present, there are two blood collection methods for blood routine testing: collection of venous blood and collection of peripheral blood. Among them, the volume of venous blood collection is large, at the milliliter (ml) level, suitable for adults and other patients who are convenient for blood collection; while the blood collection volume of peripheral blood is small, around 100 microliters (ul), suitable for children and other patients who are inconvenient for blood collection . Because the sample size of peripheral blood is too small compared with the sample size of venous blood, the two are not of the same order of magnitude. At present, for the models with mechanical automatic mixing devices on hematology analyzers, the meth...

Problems solved by technology

At present, for the models with mechanical automatic mixing devices on hematology analyzers, the method of mixing the samples in the test tubes is mainly to simulate the artificial test tube upside-down mixing method, or swing and rotate, that is, around the central axis of the test tube or The vertical line swings at a certain point on the extension line, but the above-mentioned mechanical automatic mixing method is only applicable to the mixing of venous blood samples, and cannot meet the requirements of blood routine testing for mixing a small amount of peripheral blood samples in test tubes, and is not suitable for in-test tube mixing. Mixing of peripheral blood samples

When analyzing and testing peripheral blood samples, manual shaking of peripheral blood test tubes is mostly used for mixing, which has low work efficiency and inconvenient sample mixing operation
