Novel embedded system design and implementation for automatic platelet aggregometer

The platelet aggregation function analysis is applied in clinical research and application more and more widely. In this paper, an automatic double-channel platelet analysis system PL12 is designed and realized. The system framework is based on embedded processor ARM and DSP architecture, in which a signal modulation circuit is designed. And an analog to digital conversion scheme is proposed and realized for measuring weak pulse signals of blood cells. The principle of control system and management software is also presented. Experiments validate the high efficiency, precision and stability of the system.
