Maximum expiratory pressure device |
摘要 |
An improved maximum expiratory pressure device and cough simulator including a flow tube having an integral mouthpiece at a patient input end, and a hinged door at an opposite or discharge end for sealing off the flow tube. The hinged door is held closed by a releasable trigger operable by the patient to release the door after pressure build up to simulate a cough. A foldable pressure monitoring port is provided to connect the maximum expiratory pressure device to a pressure gauge, if desired, for monitoring the expiratory pressure developed within the flow tube.
