Quality control device for a blood analyser using whole blood

摘要

The quality control system for a blood analysis apparatus (9), using whole blood, has a freezer unit with a carrier (1) for the sample tubes and a Peltier freezing block (5) to preserve a blood control samples at the temperature prescribed by the blood control sample supplier. A mechanism (12,13,14,16,17) agitates the blood cells in a slow vortex. A needle (7) takes off the prepared cell suspension for analysis. The blood analysis is compared automatically with a control sample to validate the results, and generate an alarm on a deviation. The comparison can be made by a control unit in the laboratory, or by a remote center through a communication network. The blood samples are identified by a barcode, electronic chip and/or a magnetic label.
