1, body is provided with first infrared detector that comprises emitting head and receptor, and emitting head and receptor branch are in the tube for transfusion both sides of infusion alarm top, are used for having or not of tracer liquid; Detector has data wire to be electrically connected with controller.

2, body is provided with second infrared detector, and emitting head and receptor office be the tube for transfusion port both sides in the Fei Shi dropping funnel not, is used for the flow of tracer liquid; Detector has data wire to be electrically connected with controller.

3, body is provided with LCDs and has data wire to be electrically connected with controller.

4, body is provided with wireless launcher and has data wire to be electrically connected with controller, and other is furnished with nurse station wireless receiver and portable " BB " machine receiver, and receiver is provided with display screen display alarm address, also is provided with speaker.

The present invention has following beneficial effect:

1) owing to reversing the required force rate of tube for transfusion that its flattening is much smaller, and the effect of reversing blocking-up is also effective more than flattening, utilize the energy storage principle of capacitor in addition, utilize capacitor discharge type to trigger control, so only need the very little small-capacity cells power supply of volume, i.e. may command blocking-up tube for transfusion need not to connect civil power, make the alarm volume little, in light weight, possess practicality.

2) increase work efficiency in wireless transmission warning address.To a large amount of transfusion personnel's outpatient transfusion room is arranged, effect is more obvious.
