The transmitting tube of correlation photoelectric sensor one sends a branch of directional light, and when there being drop to fall in tube for transfusion, directional light is hidden
Gear, the optical signal that the reception pipe of correlation photoelectric sensor one receives can be by dying down by force, and the electric impulse signal changed into dies down,
Power according to the signal of telecommunication determines whether that drop falls；Obtain dripping speed by the number of drops in the statistics scheduled time；To survey
The speed of dripping obtained passes to CPU, pressure in CPU control hanging bottle carry out dripping velocity modulation whole；
Liquid level warning line is arranged on the position close to bottleneck below transfusion bottle bottleneck, correlation photoelectric sensor two is installed liquid level
Warning line both sides, when liquid level is less than liquid level warning line, and the optical signal that correlation photoelectric sensor two receives becomes suddenly strong, correlation
The signal recorded is passed to CPU and processes by formula photoelectric sensor two；
The pressure of cylinder interior gas measured by baroceptor, and when pressure is less than required value, startup force (forcing) pump, to cylinder charge, reaches
Quit work to force (forcing) pump when requiring；Blood pressure according to different people and the blood pressure situation of different time people, or, according to survey
Cylinder pressure is adjusted by the speed of dripping dripped speed with arrange measured, when dripping speed less than a setting value, increase the pressure of cylinder until
Reach requirement；
Drip speed by LCDs display setting, reality drips fast, residue transfusion time, residue amount of liquid medicine and transfusion bottle pressure；Logical
Cross button settings to drip speed, select amount of infusion and tube for transfusion specification；Drip speed set-up mode to include: one is the direct setting unit time
Interior number of drops；The second is to arrange transfusion time；The third is number of drops and the transfusion time control of setting unit time simultaneously
System transfusion dose；During for the first time transfusion every day, choose tube for transfusion specification, after finishing changing liquid medicine every time, choose this amount of infusion and
Setting transfusion speed, central processing unit calculates remaining transfusion time and residue amount of liquid medicine according to the parameter arranged, and counts
The pressure information that needs in calculating transfusion bottle is also shown by LCDs.
