Non-Invasive Physiological Signal Acquisition System for Ward Monitoring
Proceedings of the 2018 5th International Conference on Bioinformatics Research and Applications(2018)
摘要
The article describes a non-invasive physiological signal acquisition system based on Ballistocardiography technology, which is applied to the ward monitoring scene to assist medical staff and reduce work consumption. The overall structure of the signal acquisition system and the key signal processing circuit are described in detail. Since the design system uses an array sensing front end, signal crosstalk between multiple channels becomes an obvious problem. In this work, the signal noise analysis and design of the sampling part of the acquisition system is carried out, and an effective measures are taken to reduce the signal crosstalk between the channels. Considering the application requirements in the ward, the electrostatic discharge (ESD) immunity design of the acquisition system was designed and passed the test of relevant standards (IEC60601-1-2).
