Description

Technical Field

[0001] The utility model relates to the technical field of medical testing, in particular to an automatic sample adding device. Background Art

[0002] The fully automatic biochemical analyzer is an instrument that measures a certain chemical component in body fluids based on the principle of photoelectric colorimetry. Due to its fast measurement speed, high accuracy, and small reagent consumption, it is now widely used in hospitals, epidemic prevention stations, and family planning service stations at all levels. Its combined use can greatly improve the efficiency and benefits of routine biochemical tests.

[0003] Different samples need to be added to the fully automatic biochemical analyzer during its operation. Since the sample storage device in the sample adding mechanism of the fully automatic biochemical analyzer is not convenient to take out for adding and flushing, there will be residues when the sample adding mechanism adds multiple sample solutions. The residual sample solutions will affect each other, resulting in deviations in the final test results. Therefore, we proposed a new automatic sample adding device. Utility Model Content
