Abstract
The utility model relates to an infusion liquid level detection and alarm device and can effectively solve the problems that existing products are inconvenient to install, high in cost and poor in practicability. The technical scheme is as follows: the device consists of two parts, namely, a transmitter and a receiver, wherein the transmitter mainly uses an opposite-type photoresistor sensor, changes of the liquid level in an infusion tube are converted into electric signals to be transmitted to a single-chip microcomputer for processing, then the processed signals are transmitted to the receiver through a wireless transmitting module, after the receiver receives non-liquid signals, a buzzer at the end of the receiver works, when the receiver receives liquid signals, the buzzer at the end of the receiver does not respond, the receiver is handheld equipment, whether the buzzer works or not is determined by the fact that whether a liquid flows through the infusion tube, and the device is similar to an alarm clock to enable a patient or an accompanying person to have an appropriate rest and be at ease without worrying about dangers due to the fact that a medicine liquid is used up. The device is simple in structure, convenient to install, low in cost and high in practicability and is an innovation on infusion liquid level detection and alarm devices.
