Automatic single sample introduction device of blood cell analyzer

Abstract

The invention discloses an automatic single sample introduction device of a blood cell analyzer. The automatic single sample introduction device mainly comprises a transverse feed mechanism fixed on the blood cell analyzer, a longitudinal feed mechanism fixed on the transverse feed mechanism, a sampling mechanism fixed on the longitudinal feed mechanism, and a rotary sample introduction mechanismwhich is positioned below the transverse feed mechanism and fixed on a rack of the blood cell analyzer. Compared with the prior art, the device has the advantages that: by arranging the rotary sampleintroduction mechanism, a test tube is inserted into a test tube placing hole on a sample introduction base after manual uniform mixing to realize automatic introduction of a single blood sample and a test tube cover does not need to be taken down manually, so that a sampling needle can be totally isolated from the hand of people, and potential hazard of possibly puncturing the hand can be avoided during the conventional single blood sample test; moreover, the device can be operated more safely and easily; and the sampling mechanism can move in the horizontal and vertical directions, so the sampling needle is positioned more flexibly. The whole sample introduction device has a simple structure and high automation degree.

Description

technical field [0001] The invention relates to a blood cell analyzer, in particular to a single automatic sampling device on the blood cell analyzer. Background technique [0002] Blood cell analyzer is a commonly used blood analysis instrument at present, which is used for qualitative and quantitative analysis of blood cells in clinical tests. At present, the sampling devices of many types of cell analyzers are multiple automatic sampling devices, which can realize continuous automatic testing of multiple samples. However, when only individual or a few samples are tested, the multiple automatic sampling devices provided in the hematology analyzer are usually not used for inspection, but the blood in the test tube is manually mixed, and the test tube cover is removed. After the test tube is close to a specific area for blood collection, the sampling mechanism is activated to perform blood sampling, thereby completing the sampling operation. Since the test tube is in an un...

AI Technical Summary

Problems solved by technology

Since the test tube is in an unsealed state during sampling, the blood sample in the test tube is easy to flow out, which increases the probability of contact between the blood sample and the human body; In the place of contact, it is easy to injure the hands during the sampling operation, and there is a certain potential safety hazard
