Embedded control and management system for novel automatic platelet aggregometer
Platelet aggregation assay is important in mediating platelet thrombus formation for both medical treatment and prevention. Therefore quick and accurate automatic analyzers for clinic are of urgent requirement all the time. In this paper, design and implementation of embedded control and management system for novel automatic platelet aggregometer is presented, which comes to rapid and quantitative measure of platelet aggregation and other platelet-function for assay. The system is based on ARM-DSP dual-core embedded processor framework for device control and management. Automatic control of testing process is introduced and a signal modulation and detection circuit is proposed for measuring blood cell's weak pulse signals, as well as principle of the control and management system software is given in detail which supporting a reliable system control and operation. The new system achieves effective and accurate platelet aggregation assay and overcomes the drawbacks of conventional manual operation of platelet-function assay. Experimental results validate the effectiveness and precision of the system.
