Safety transfusion / Medicine

Safety transfusion
Safety transfusion

For waiting time during the infusion is too long, most people stay in bed or read a book.to pass the time.They won't notice the remaining liquid.Without attention, it will easily lead to blood circulation, and even danger the life safety for the air comes into the vessels.
To solve this problem, we add a yellow ball into the dropper infusion tube.The ball will float in the liquid and decrease with the reduction of liquid. When the liquid medicine used up, the ball will stick with the dropper bottom through the infusion tube and prevent the air to enter, so that the liquid medicine no longer drops,which prevents the backflow of blood.
