Described data on flows processes and displays device is outside to also have a data on flows output interface, and is connected with single-chip microcomputer.
The utility model can adopt powered battery, is the intermittent power supply circuit.
Advantage of the present utility model shows:
Adopt differential pressure pickup that pressure reduction is gathered, single-chip microcomputer is handled the back to data and is shown oxygen flow by display screen, this mode accurate measurement, and can show the oxygen real-time traffic, can show the oxygen integrated flow again, can single patient use, also can solve an oxygen charging difficult problem that is always perplexing hospital by the Management Calculation interconnect plane of interface and hospital.The utility model also has advantage simple in structure, that cost of manufacture is cheap.
