MEDICAL PERFUSER BY GRAVITY WITH A BALL INTENDED TO STOP THE PASSAGE OF THE AIR AT THE END OF THE INFUSION

摘要

The present invention relates to a novel medical infusion set by serum gravity used in a human or an animal that stops the passage of air from the drop chamber (4) to the tubing (9) of the infusor at the end of the infusion. As soon as the bottle of serum to be infused is emptied of its contents and at the end of the infusion, a plastic ball (6) located inside the chamber drops (4) drops and closes the orifice (11). ) of the tubing under the action of the force of attraction of the serum in the tubing (9) and the gravity on the ball It descends first before the level of the serum (8) in the channel (12) marries the bottom of this channel (12) and closes the orifice of the tubing (11) preventing the passage of air in the tubing The use of the conventional infusor passes air in the tubing at the end of infusion
