Research on Flow Sensor and the Pressure Sensor with Digital Asthma Diagnosis Technology

Abstract:

The essay discusses on the flow sensor and the pressure sensor, which collect the signals of PEFR(peak expiratory flow rate) and FEV1(forced expiratory volume in 1 second) of the human body. After the two analog signals go through signal conditioning circuit, ATMEGA128 collects the correspondent digital signals so that realizing fast measuring the PEFR and FEV1, and the result of the diagnosis on the patient’s diseases will directly appear on the LCD, at the same time storing dynamic data as objective index for doctors’ prescriptions and disease analysis. The multiparameter digital asthma diagnosis instrument has a large range of measurement and highly accurate measuring ability, with a small size and high cost, suitable for rural medium- and small-sided hospitals and domestic supervisions.
