The multi-functional transfusion monitoring and heating mobile hanger of the present invention innovatively designs a new type of infusion set, and is combined with a light-emitting diode and a photosensitive sensor to monitor the infusion status by using a photosensitive resistor for light-sensitive changes, and when the infusion of the medicinal solution is blocked or stopped abnormally , or when the liquid medicine infusion is finished, the prompt alarm device is automatically activated, which not only solves the problems of difficult to accurately grasp the infusion time and inconvenient care, but also greatly improves the safety of infusion. In addition, through the design of the heating device, the discomfort caused by the low temperature of the medicinal solution to the human body during infusion in winter can be reduced. At the same time, through the design of wearing components, it brings great convenience for patients and patients to move freely, drink water, eat and go to the toilet during infusion. The present invention designs a photosensitive resistor to realize a monitoring and alarming device, and adopts exquisitely designed, simple and commonly used, low-cost common electronic components, low cost and low cost, which is more conducive to popularization and use, and benefits the society.
