The invention provides a novel medicament flow measuring device which is divided into four modules, namely a medicament metering
assembly, an energy transmission
assembly, a generator set and a light-emitting and sound-producing device group, the medicament metering
assembly comprises a medicament metering
barrel and a weight, and the outer wall, 5cm away from the mouth of the metering
barrel, of the medicament metering
barrel is connected with a transmission rod live shaft; a rotating shaft is arranged at a position 5cm away from the bottom of the metering barrel and is connected to a
metal fixing rod; the energy transmission assembly comprises a transmission rod, a
crank handle, a transmission gear and a
metal wheel disc; the generator set comprises a
motor generator, a matched transmission gear, a
metal conductor wire and a screw, the position of the transmission gear is adjusted, the
motor generator is fixed on the support, and the metal conductor wire is led out of a current output end and is fixed through the screw after extending to the fixing plate; and the light-emitting and sound-producing device group comprises an
LED lamp, a sound generator and a metal conductive wire. The device is convenient to check the dosage, energy-saving, environment-friendly, and convenient and flexible in adjustment process.
