RESUMO
This paper discusses the design of a special digital manometer for air-pocket in manual air-way. Integrated silicon pressure sensor MPX5010 with high precision and sensitivity is adopted in the device. It can not only measure and display air pressure of air-pocket,but also give the alarm for excessive pressure,thus providing a timely and convenient way for clinician to control air-pocket pressure,which ensures the safety and precision for clinic.
RESUMO
Objective To develop a continuous temperature monitoring device for the infant,with the function of high temperature alarm.Methods The comparator and counter of MSP430F435 SCM and some peripheral circuits was applied to high-precision temperature measurement,and then the data were stored in the flash of MSP430F435 SCM.Results The device could display realtime temperature and alarm in case of abnormal temperature,which made continuous monitoring of 30 days realized.Conclusion The device,being low-cost,low-power-consumption and low-volume,is worth popularizing for dynamic monitoring of infant temperature.
