Design and implementation of hospital infusion monitoring and alarm system

With the development of science and technology and the progress of society, people have benefited from modernization and the convenience of science and technology in all aspects. However, the relationship between doctors and patients in today’s society has always been the focus of contradictions that easily lead to disputes. In terms of infusion, problems such as bulging infusion caused by insufficient medical staff also occur from time to time. At present, the most widely used and easy-to-master infusion method is intravenous infusion. According to the patient’s condition and medication, the infusion speed is often different. However, in the specific operation, nurses often adjust the infusion speed manually by experience. Although this method is easy to use and master, in actual operation, the inexperienced medical staff may not be particularly accurate in grasping the drip speed during infusion, which is prone to problems such as patient discomfort. Continuous work, coupled with the shortage of personnel, is prone to medical accidents, thus increasing the pressure on medical staff. Therefore, it is particularly important to make a relatively low-cost and easy-to-use infusion alarm to meet this need. Therefore, taking AT89C51 as the central control unit, the design is relatively simple and the cost is relatively low. With 3mm red led, LCD1602, resistor, infrared optocoupler, 8550 triode and stepping motor, an infusion alarm based on 51 single chip microcomputer is designed, hoping to play a certain role in infusion speed control and end warning. This paper will introduce and explain the hardware and software of infusion alarm in detail from various aspects.
