Ruschke ABSTRACT OF THE DISCLOSURE A drip chamber assembly is provided which includes a chamber that is flexible but is non-collapsible under a negative pressure condition. The chamber, being flexible, yields to priming easily, but when restriction is added to the inlet port the chamber will not collapse and aspirate air to the patient. A flexible chamber is formed of a vinyl plastic material having a thickness of about 0.04 inch to 0.08 inch and a durometer reading of about 61 shore A to 81 shore A. End caps rigidly support each of the ends of the chamber with the end caps each having a contact length along the chamber of at least 0.2 inch. -1-
