Safe infusion drip tube

The utility model relates to a safe infusion drip tube. The safe infusion drip tube is characterized in that an existing straight tube is changed into a bent tube structure; the safe infusion drip tube comprises a straight tube section at the upper part and an inclined tube section at the lower part; the straight tube section and the inclined tube section are in natural transition connection; the included angle between the straight tube section and the inclined tube section is in the angle range of 110 degrees to 160 degrees. The safe infusion drip tube is reasonable and simple in structural design and safe and reliable to use; the straight tube is changed into the bent tube, so that effective angular displacement is carried out on the dropping liquid direction and the floating bubble raising direction, and the generation of bubbles caused by dropping liquid is avoided; moreover, a buoyancy ball valve is designed at a liquid outlet, potential safety hazards generated when medicine liquid drains away can be effectively avoided, the working strength of medical staff can be alleviated, whole process monitoring by medical staff in the infusion process is not needed, the air exhaust operation is reduced, the time and labor are saved, and the practical effect is good.
