Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
A kind of clinical air bag press device, comprise air bag 1, air bag is arranged pressure transducer 2, pressure transducer is connected with analog to digital conversion circuit 3, analog to digital conversion circuit is connected with single-chip microcomputer 4, single-chip microcomputer is connected with the air pump 6 to air bag air feed by power driving circuit 5, the pipeline between air pump and air bag is arranged electric control valve 7.Electric control valve is connected with single-chip microcomputer.Single-chip microcomputer also can be connected with man machine interface 8.
This utility model principle is:
After adopting manual mode to confirm pressing position and the degree of depth, adopt pressure air bag and strapping tape to replace hand pressing, and keep constant pressure by sensor and air pump, and accomplish adjustment in time and warning, after special time, automatically terminate pressing.
Single-chip microcomputer is the control core of whole system, is connected, is commutated by air valve with automatically controlled 2/3 valve, realizes inflation and the venting of air bag; Be connected with power driving circuit circuit, by faint Single-chip Controlling signal, control unlatching and the stopping of air pump, realize airbag aeration;
Accept, through the pressure sensor signal of analog to digital conversion circuit conversion gained, to obtain the pressure of airbag gas, and by airbag aeration, be that airbag gas pressure keeps constant.
The output gas of air pump inputs air bag after automatically controlled 2/3 air valve; Air bag is connected with pressure transducer, and pressure transducer can measure air bag pressure, and converts analog voltage signal to; This voltage signal, after analog to digital conversion circuit, is got by monolithic is machine-readable, and is converted to air bag pressure numerical value.
