Publication number: 20230310786Abstract: Disclosed is a fluid trap for use with, or comprising part of, a respiratory therapy system, and in particular comprising part of, or configured to be connected to, a breathing limb, such as an expiratory limb, of a respiratory therapy system. The fluid trap comprises a container configured to contain fluid received from an inlet; a closure, the closure and container being configured to be removeably mounted together to close the container; and a valve configured to be removeably mounted on at least one of the container and the closure, and configured to be in a closed condition which prevents fluid from flowing through the inlet when the closure is not mounted on the container, the valve being further configured to be in an open position which allows fluid from the inlet into the container when the closure is mounted on the container.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Inventors: Nathan Lee Gray, Telge Nishan Chaturanga Peiris, Paul Joseph Moody
