The invention provides an automatic electronic infusion alarm which comprises a shell, a sensing module, a control module, an alarm range adjusting module, an alarm display sound module and a
direct current power module. According to the alarm, a pressure
signal is converted into a weak
electric signal, so that pressure change of an infusion
bottle is acquired, and the defects of other induction
modes are fundamentally overcome; the adopted
pressure sensor is simple in principle, the influence caused by physical interference factors such as external sound, light,
electricity and
magnetism is small, and the error is small; circuits of the control module are integrated to a PCB, and convenient for split charging; the alarm quality is adjustable by
voltage dividing through a
resistor, and the alarm has the advantages that corresponding threshold values can be set aiming at different infusion
bottle specifications, and the design is humanized; the principle of the whole device is easy to understand, and the device is convenient to assemble, use and maintain by
medical care personnel; and moreover, the cost is low, the medical demands on the general
population can be greatly met, and the device disclosed by the invention is small in size, low in
power consumption and convenient to fix and use in the hospital and can be widely applied to various large and small hospitals and large and small clinics.
