This invention is a device (10) for inspiration of a mist from a nebulizer,
having an inlet connector (12, 32) adapted to engage an outlet port of a
nebulizer, a hollow mouthpiece element (126 34) for insertion into a patient's
mouth; a conduit (14) forming a fluid connection between the inlet connector,
and the hollow mouthpiece element. An exhaust valve (26) is provided for
removing expiratory gases which are exhaled into the mouthpiece element to the
ambient atmosphere via an exhaust/positive expiratory pressure (PEP) valve (26,
50). The PEP valve is positioned on the conduit between the inlet connector,
and the mouthpiece element; and a filter housing (44) containing a filter
(60) for filtering the exhaled gases passing from the exhaust/PEP valve.
