Claims

[Scope of utility model registration request]

A sealable chamber that accommodates a subject, a trachea whose one end can be connected to the subject's oral cavity and whose other end can be opened and closed by a shutter, and a pressure gauge that measures pressure changes within the trachea. A body plethysmograph that includes a volume meter that measures changes in the volume of the chamber and measures the functional residual capacity of the subject's lungs from the output of the pressure gauge and the output of the volume meter when the shutter is closed, A body plethysmograph comprising a pump device connected to the trachea and changing the pressure within the trachea.
