Abstract:
Objective To design an inflatable bed aerator to replace the traditional inflator pump.Methods The aerator used MCS-51 SCM micro control unit as the core component and compressed air as the air source,which was composed of the modules for main control,power supply,air pressure detection,liquid crystal display,button as well as real-time clock and alarming.Results The aerator gained the same efficacy as the traditional inflator pump,while the noise was decreased to the patient and medical staffs,which behaved particularly well for the bedsore prevention of the critical patient.Conclusion The aerator has simple structure,easy operation and high stability,which can be used for the inflation of two air cushions simultaneously and for timely alarming against failures,and thus is worthy promoting practically.
