Infusion early warning method and equipment

The invention relates to the technical field of medical auxiliary equipment, and discloses an infusion early warning method and equipment. According to the infusion early warning equipment, by using a sensor arranged at the opening of an infusion bottle, the current pressure value and the current infusion velocity are detected in real time, according to the detected current pressure value and the current infusion velocity, the remaining infusion time is calculated, the remaining infusion time is compared with a preset time duration, whether the remaining infusion time is smaller than the preset time duration is judged, and when the remaining infusion time is smaller than the preset time duration, liquid inside the infusion bottle is little left, and the infusion is almost finished. Then, the infusion early warning equipment generates warning information, the warning information is sent to related terminal equipment, a medical staff can timely adopt a corresponding measure according to the warning information, the patient and family members do not need to pay attention to the infusion schedule, a blood backflow condition can be effectively avoided, and the problem that the patient can not take a rest during the infusion period can be solved.
