Development of a low cost multi-parameter wireless spirometer which has a friendly interface and can wirelessly network within hospital. Using the self-designed laminar flow sensor to transform the flow into the signal of voltage. Then the voltage signal would be sampled and proceed by the STM32, and the results would be shown on LCD and also can be transmitted to hospital by the module of GPRS. The system can not only detect routine lung function parameter, but also the unconventional indexes as partial mean transit time (MTTp), and can display V-T curve Flow-T curve and MEFV curve. In addition, the acquired data can be sent to the PC by GPRS module for doctors referring to. The results of a clinical trial showed no significant differences compared to the standard spirometer. The system has characteristics with small volume, low cost, friendly interface and simple operation, being suitable for families and small scaled hospitals.
