Dependable ward transfusion dripping-speed monitor

The invention discloses a dependable ward transfusion dripping-speed monitor. The dependable ward transfusion dripping-speed monitor comprises a shell and a circuit part; the shell is provided with a dripping cup cavity; the upper end of the dripping cup cavity is provided with a limiting plate; two sides of the dripping cup cavity are provided with two routes of detecting devices consisting of a helium-neon laser and a phototriode; the collector electrode of the phototriode is connected to the reverse input end of an operational amplifier by a resistor R5, and the reverse input end of the operational amplifier is connected with a power supply by a potentiometer R6; the base electrode and the collector electrode of a triode Q1 are respectively connected with the transmitting electrode and the collector electrode of the phototriode; and the output end of the operational amplifier is connected with the input end of a first single chip. The transfusion dripping-speed monitor is capable of, through installing two routes of detecting devices, effectively and accurately measuring the transfusion dripping-speed, ensuring the accuracy of the measuring data. The monitor has novel, scientific and rational detection principle, reliable and accurate detection result, strong dependability, and obvious beneficial effect, and is promoted and applied conveniently.
