Drip chamber with automatic vent and shutoff

A drip chamber for intravenous (IV) fluid infusion, the drip chamber comprising:

• a drip chamber body having a proximal region and a distal region each at least partially defining an internal volume within an interior of the drip chamber;
• an inlet tube configured to drip the IV fluid into the interior of the drip chamber at the distal region;
• an outlet tube extending inward into the interior of the drip chamber body from the proximal region, the outlet tube being in fluid communication with the interior of the drip chamber to allow the IV fluid to flow out of the drip chamber;
• and
• an air vent configured to automatically prevent venting of gases out of the interior of the drip chamber if the IV fluid filling the interior of the drip chamber is above a predetermined fill level, and to automatically vent gases out of the drip chamber when the IV fluid falls below the predetermined fill level, the predetermined fill level corresponding to a volume less than the internal volume of the drip chamber, wherein the air vent includes an exhaust disposed at the proximal region, an air vent intake disposed in the internal volume, and a pickup tube extending distally into the internal volume from the exhaust towards the air vent intake to fluidly couple the air vent intake and the exhaust.
