Abstract

A drip chamber device may include a housing including an inlet and an outlet disposed downstream of the inlet, and a chamber defined by an inner circumferential surface of the housing. The chamber may fluidly connect the inlet with the outlet. A valve member may be disposed in the chamber to move between (i) a closed state where fluid communication between the inlet and the chamber is blocked, and (ii) an open state where fluid communication between the inlet and the chamber is not blocked, based on a level of fluid within the chamber.
