Work process illustrates:
Weight sensor detects the current weight of medicinal fluid bag, its gravimetric value enters control circuit by the first A/D converter, if weigh less than preset value, illustrate that the amount of liquid medicine in medicinal fluid bag is about to exhaust, sent by control circuit and report to the police and drive relay to make the action of electric magnet chuck, block tube for transfusion, anti-return blood, and prevent other from entering in blood.
Concurrently, liquid level sensor detects the current level in liquid bucket, 1/2 liquid bucket liquid level place during liquid level sensor is arranged, be preset height, when liquid level is higher than liquid level, the light intensity that receiving tube in infrared emission pipe receives is lower, and liquid level lower than liquid level time, the light intensity that receiving tube in infrared emission pipe receives is higher, light intensity value enters control circuit by the second A/D converter, judge that liquid level makes lower than preset height thus, once detect that current level is lower than preset height, illustrate that medicinal liquid is about to exhaust, sent by control circuit and report to the police and drive relay to make the action of electric magnet chuck, block tube for transfusion, anti-return blood, and prevent other from entering in blood.
Chuck reset switch is used for reset electric magnet chuck, once electric magnet chuck reset switch is pressed, then control circuit control relay resets, and electric magnet chuck is unclamped, thus can normal infusion.
