Infusion Ball / Medical product

INFUSION BALL
We usually ignore observing the medicinal liquid level in the infusion. That makes us have no idea about the situation of the medicine dripping ,and blood back flowing happens. The purpose of this design is to solve the problem. We add a small hollow ball in the dropper. When the medicine is enough, the ball will keep floating on the rolling liquid. But if the medicine is dripped to the end, the ball will get down to the bottom of the dropper with its own gravity. That can seal the vessel and maintains the medicinal liquid in the lower half of it. So it can avoid blood to flow back.
