Background

In the medical field, various liquid delivery systems have been used for delivering liquids (e.g., drugs, nutrients, saline, etc.) into a patient. There are two main types of liquid delivery systems in common: the infusion bottle or the infusion bag is hung at a high position, liquid in the infusion bottle or the infusion bag flows into the drip chamber along a thinner infusion hose under the action of atmospheric pressure, and when the pressure of a water column in the drip chamber is greater than the venous pressure, the liquid in the bottle flows into veins along the hose; secondly, an infusion pump is arranged at the rear end of the infusion tube, the infusion pump is used for conveying the injection to the patient at a stable conveying rate, and the pumping rate of the infusion pump is controlled to accurately control the flow rate of the injection. Therefore, the accurate measurement of the flow rate (dripping speed) of the injection liquid in the infusion tube is the key point of adjusting the flow rate or the flow rate through a flow rate regulator or an infusion pump.

At present, an infusion alarm for monitoring the infusion condition of an infusion apparatus has appeared, a common infusion alarm is internally provided with a light receiver which is used for generating an electric pulse signal after receiving a light signal reflected when a water drop drops, the electric pulse signal is transmitted to a signal input end of a single chip microcomputer through a circuit connected to the single chip microcomputer, the single chip microcomputer receives the electric pulse signal generated by the light receiver in a reference time period, the single chip microcomputer judges that the infusion alarm works normally according to a preset program, and if the condition of too high, too low or blockage of the dropping speed occurs, the single chip microcomputer triggers the built-in alarm to send out alarm sound.
