Gravitational, magnetic, floating ball valve
First Claim
Patent Images
1. A gravitational, magnetic, floating ball valve inside a transparent second container for use in the infusion of a fluid into a patient comprising:
- a first perforated and hollow cylindrical container having an upstream end and a downstream end, and inserted in an outlet port of a transparent second container;
a first, floating, magnet-containing ball having a predetermined specific gravity, freely positioned within said first perforated and hollow cylindrical container; and
a second apertured magnet fixed at said downstream end of said first perforated and hollow cylindrical container;
wherebyupon infusing a vital fluid into a patient by an intravenous method, said floating magnet containing ball positioned upstream is attracted to said second apertured magnet positioned downstream when the supply of an infusion liquid is near depletion, thereby closing off the supply of fluid to prevent backflow of the infusion liquid and the possible inclusion of air into the body of a patient.
