Safety controller for universal connection of ordinary blood transfusion sets

Abstract

A safety controller universally connected to ordinary blood transfusion infusion sets. It is composed of an upper drip cup, a lower drip cup, and a floating cup located in the lower drip cup. A safety controller is formed on the upper end of the upper drip cup. There is a sleeve part, the inner edge of the sleeve part forms a hollow liquid inlet, and the inner diameter of the liquid inlet of the sleeve part is larger than the outer diameter of the outer tube part protruding from the lower end of the blood transfusion set, so that the safety controller can The sleeve part is directly combined with the outer tube part of the blood transfusion set, and a stopper can be set between the edge of the upper end of the lower drip cup and the inner edge of the upper drip cup. The stopper is located on the float. The cup floats on a path in the drip cup to limit the floating height of the float cup, making the float cup more stable and reliably blocking the flow of liquid from the liquid outlet in the drip cup.
