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 new medical infuser by gravity of serum used in a human being, or in an animal, which stop the passage of air from the chamber into drops (4) towards the tube (9) of the needle at the end of infusion. As soon as the vial in the serum for infusion is emptied of its contents, and at the end of the infusion, a ball (6) made of plastic which is located inside the chamber into drops (4) descends and closes the orifice (11) of the tube under the action of the force of attraction of the serum in the tube (9) and the gravity on the ball it descends in the first, before the level of the serum (8) in the channel (12) matches the bottom of this channel (12) and closes the orifice of the tube (11) preventing the passage of air into the tube, the use of the filling infuser conventional lets air into the pipe at the end of infusion
