Design of Signal Ampliifcation Circuit for Pressure Sensor of the Prevention and Treatment Trousers for Vasovagal Syncope
摘要
Abstract
Objective To design a signal ampliifcation circuit for the pressure sensor of the prevention and treatment trousers for vasovagal syncope in order to test the therapy pressure. Methods The suitable pressure sensor was selected according to the requirements of pressure testing, accuracy, size and cost of the equipment, and then the corresponding signal ampliifcation circuit with several functions including ifltering, signal isolation and signal ampliifcation was designed. Results The output signals which were magniifed by the circuit were steady and the interference of these output signals was little. Conclusion The signal ampliifcation circuit can be used to test the therapy pressure of the prevention and treatment trousers for vasovagal syncope.关键词
