Electronic infusion alarm

Abstract

The invention relates to the technical field of electronics, in particular to an electronic infusion alarm. The electronic infusion alarm comprises a device shell, a working circuit board is arrangedin the device shell, the working circuit board is connected with an alarm indicating lamp, the alarm indicator lamp is mounted on the outer surface of the device shell, a buzzer and a range knob are arranged on the surface of the device shell, an infusion bottle hook is connected to the lower end of the device shell, a hanging hole is formed in the outer surface of the upper portion of the deviceshell, a pressure sensing device is arranged on the inner surface of the device shell, a hardware system structure of the alarm is composed of a direct-current power module, a sensing module, a control module and an alarm module, and the control module comprises a signal amplifying module, a range adjusting module and a control quality module. The alarm module comprises a buzzer and a light-emitting diode. The alarm is low in manufacturing cost, simple in principle and simple and convenient to operate, is convenient to popularize and easy to debug, and has a good application prospect.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic infusion alarm. Background technique [0002] When patients are infused in the hospital, they generally need the care of nurses or family members. However, the time for infusion is generally long and there are many things in the hospital, so it is inevitable that there will be a shortage of staff. If unattended, the patient will worry about the infusion process all the time during the infusion, which will cause great mental pressure to the patient and prevent him from getting a good rest during the infusion. Although failure to pull out the infusion needle in time will not bring life danger, the phenomenon of venous return of blood will bring certain panic to patients who do not have basic medical knowledge and affect the normal work of the hospital. The electronic infusion automatic alarm can send out an alarm in time when the droplet is reduced to a certain ...

Problems solved by technology

Undoubtedly, the cost of using this method is low, but there are certain safety hazards, such as whether the medicinal properties will be affected when the liquid is electrified, and the work of disinfecting the electrode every time it is used is too cumbersome, so this method is only Staying at the theoretical level, it is impossible to form productivity, the principle of ultrasonic sensors, but the device based on this principle is not only expensive, but also requires complicated installation and debugging, and the reliability is not guaranteed, so it is difficult to detect droplets in intravenous infusion. widely used
