Publication number: 20220268661Abstract: A method is provided for detecting leaks in a disposable medical fluid cassette that includes a base and a flexible membrane attached to the base in such a way that the base and the flexible membrane cooperate to at least partially form a fluid passageway. The method includes applying a first force to the flexible membrane, measuring a first physical property of a system that includes the medical fluid cassette a medical fluid pumping machine, removing the first force from the flexible membrane, applying a second force to the flexible membrane, measuring a second physical property of the system, and determining whether the medical fluid cassette leaks based on a comparison of the first physical property and the second physical property.Type: ApplicationFiled: February 9, 2022Publication date: August 25, 2022Inventors: Kulwinder S. Plahey, Jie Zhu, Tri Ly, Robert Matthew Ohline, William Scott Crawford
