1. Ordinary PVC gravity infusion sets are prone to fatigue rupture and elastic attenuation under the peristaltic extrusion of the infusion pump.

2. The dripping speed of the liquid can only be controlled by manually setting the dripping speed, but the dripping speed of the infusion can not be intelligently controlled according to the patient's physiological condition.

3. The automatic closing device is irreversible. Once it is closed by mistake, it is difficult for the patient to open it by himself, which also increases the cost of the equipment.

4. It can only send an alarm when the liquid level reaches the warning position, and cannot give real-time feedback to the patient on the liquid dripping speed and the remaining infusion time.

5. Failure to call the police in time when adverse infusion reactions or drug allergies occur in patients, resulting in many medical accidents.

6. It is impossible to intelligently control the drip speed of each device according to the overall data in the system to avoid the completion of infusion by multiple patients at the same time, causing nurses to work nervously.

7. It is impossible to scientifically and intelligently manage the infusion situation of the entire patient group, and record the physiological response of the patient in the infusion to facilitate the doctor to make an accurate diagnosis for the patient.
