Abstract:
Objective To design a wireless oxygen concentration monitoring device to solve the existing problems.Methods The device was composed of an oxygen sensor,an oxygen sensor line,an oxygen concentration monitoring host and a display terminal.HT67F489 was used as the main control chip,KE-25 oxygen concentration sensor was applied to collecting oxygen concentration data,and then through the T82 module wireless transmission of the data was executed to the display terminal of the App software.Results Clinical trials proved the measure value by the device was the same to that by the equipped meter,which facilitated the medical engineer find the faults in the shortest time.Conclusion The device gains advantages in easy installation,stable performances,high accuracy and anti-interference against physical environment,and thus has high social and economic benefits.
