摘要 |
An apparatus for testing pulmonary devices such as endotracheal tubes and connectors is disclosed. The apparatus forces a predetermined volume of air or gas through the pulmonary device in accordance with a preselected waveform in a first and/or second direction under conditions that simulate an in-patient use environment. The device also measures the amount of work required to force the air or gas through the device under selected conditions. In a preferred embodiment of the invention, the device produces a laminar or turbulent flow of gas.
