Emptying device of infusion tube

The invention relates to an emptying device of an infusion tube, and belongs to technical field of tools. The emptying device can effectively and quickly eliminate air entering the infusion tube due to carelessness in the medical infusion process. The infusion tube is clamped in the middle by a driving wheel driven by a motor and a driven wheel, the emptying device of the infusion tube moves relatively to the end with air along the infusion tube after the motor is started, air in the infusion tube is extruded out of the infusion tube due to the clamping effect of the driving wheel and the driven wheel, and emptying of the infusion tube is realized. 输液管排空装置，属于其它技术领域为工具，它可有效快速的排除医疗输液过程中，因不慎导致的输液管中进入的空气。通过电机带动的主动轮及被动轮，将输液管夹持在中间，启动电机后，输液管排空装置就会沿着输液管向有空气的端做相对移动，由于主动轮与被动轮的夹持作用，输液管中的空气就会被挤出输液管，实现了输液管的排空。
