Specific use process is as follows for a kind of inflation/deflation cuff apparatus of the utility model：
After utility model device cuff 1 is strapped on the arm of human body, starts acquisition blood and detached, added at this time
Air pump 4 is started to work, and air bag 12 starts to inflate, and needs to increase to 1 pressure of cuff into clinical 50 ± 5mmHg of standard value.Work as pressure
Force snesor 6 monitors pressure in 50 ± 5mmHg ranges, and additional control system stops the 6V driving voltages of broken aerating pump 4
It only pressurizes to cuff 1,1 system of cuff is in pressure balance stable state at this time, and 7 no power of gas bleeder valve does not work at this time, is in
Closed state.After a period of stabilisation, it is influenced by air-tightness at pipeline center tap, it will have the pressure loss, when pressure passes
Sensor 6 monitors pressure in 45mmHg or less, and control system will turn on the 6V driving voltages of aerating pump 4, restore 1 system of cuff
Pressurization, pressure sensor 6 monitors that pressure is rising in 1 system pipeline of cuff at this time, when pressure is increased beyond 55mmHg, control
System processed will discharge certain gas pressure to the energization of gas bleeder valve 7 and reach within 50 ± 5mmHg, give gas bleeder valve 7 to power off immediately,
The 6V driving voltages of broken aerating pump 4 are stopped pressurizeing to cuff 1 by control system simultaneously.It has been achieved auxiliary in gatherer process
Help pressurization and pressure balanced effect.
When returning step starts, the 6V driving voltages of broken aerating pump 4 are stopped pressurizeing to cuff 1, together by control system
When to gas bleeder valve 7 energization discharge all gas, blood is fed back, until next circle collection process starts.Instantly
When one circle collection process starts, control system closes gas bleeder valve 7, to 6V driving voltages in the confession of aerating pump 4, by cuff 1
Pressure increases to clinical 50 ± 5mmHg of standard value.Move in circles in this way, with its working principle is that：It is to utilize pressure sensing
The air pressure in pipeline is adjusted in technology, the final function of realizing automatic inflatable pressure.
It should declare, the control system being previously mentioned during above-mentioned use, is to the utility model whole device inflation/deflation
The control system controlled, the actual pressure and clinical pressure mark that concrete operating principle is detected according to pressure sensor
Quasi- value operates, it is therefore an objective to control whole system.This point is conventional and easy to those skilled in the art
It is conventional in realization, and in the prior art, it is not particularly limited and illustrates herein, as long as can realize to the utility model
The system that automatic inflatable cuff apparatus is controlled.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
