A drip chamber is a medical device used in intravenous (IV) therapy. It is typically a small, transparent container that allows healthcare providers to monitor the flow of fluids or medications being administered to a patient. The chamber collects any air bubbles that may enter the IV line, preventing them from reaching the patient. The drip chamber is usually connected to an IV bag containing saline, medications, or nutrients. By observing the fluid level and drip rate in the chamber, medical staff can ensure that the patient receives the correct dosage and maintain proper hydration.
