Operation principle: when the medicinal liquid in infusion bottle does not arrive bottleneck, the first latten(-tin) 5-1, the second latten(-tin) 5-2 and the medicinal liquid between the two form capacitance type liquid level device C
x, the size of capacitance depends on the dielectric constant of two media between capacitor plate, when between two capacitor plates, without medicinal liquid, during for air dielectric, dielectric constant is 1, C
xcapacitance is very little; When having medicinal liquid between two capacitor plates, dielectric constant is much larger than 1, C
xcapacitance enlarges markedly.Capacitance when two pole plates are full of medicinal liquid is more than or equal to reference to electrochemical capacitor C
0capacitance; The capacitance of two pole plates during without medicinal liquid is less than with reference to electrochemical capacitor C
0capacitance.
Square-wave generator sends symmetrical square wave, through D1, D2 to C
x, C
0charging.During positive half cycle, to C
0charging, during negative half period, to C
xcharging, all the other times two electric capacity are through resistance R 1 (or R2) and R3 electric discharge, if C
x, C
0capacitance is equal, and R3 no current passes through, the base stage no-voltage of VT1, VT1 cut-off; If C
xcapacitance be greater than C
0capacitance, the sense of current of R3 is for upwards, the negative voltage that the base stage of VT1 loads, VT1 cut-off; If C
xcapacitance be less than C
0capacitance, the sense of current of R3 is downwards, the bias voltage of the forward that the base stage of VT1 loads, VT1 conducting.
When the medicinal liquid in infusion bottle does not arrive bottleneck, clamper 5 has detected medicinal liquid, C
xcapacitance be more than or equal to C
0capacitance, VT1 cut-off, 2 feet of NE555 are high level, NE555 is in stable state, the 3 foot output low levels of NE555, LQ46 does not drive signal, does not work, loudspeaker BL does not ring.
When the liquid level decline of medicinal liquid, lower than position of bottleneck, clamper 5 can't detect medicinal liquid, C
xcapacitance be less than C
0capacitance, VT1 conducting, 2 feet of NE555 are pulled to low level, NE555 upset, enters transient state, the 3 foot output high level of NE555, LQ46 obtains driving signal work, drive loudspeaker BL output audio signal, and this audio signal is burning before LQ46 dispatches from the factory, for disposable burning behavior, can not edit, can customize in advance, such as recording information such as " transfusion have completed, and asks pulling needle ", this audio-frequency information is play always, until there is people to process, switch S 1 is disconnected and just being stopped.
In playback of audio information, because of the 3 feet output high level of NE555, the electromagnet coil K of electromagnetic clamp 6 is obtained electric, electric magnet attracts the ferrum of another chuck close, presss from both sides flat tube for transfusion, and stopping infusion waits for that nurse carrys out pulling needle.
