1. A medical device for monitoring a physiological pulmonary condition of a user, comprising:
at least one mouthpiece, and
a transducer housing, the at least one mouthpiece and the transducer housing being separate elements, the at least one mouthpiece being physically attachable to the transducer housing,
the at least one mouthpiece, when attached to the transducer housing, being configured to pass at least part of a flow of exhaled or inhaled air through the mouthpiece to the transducer housing,
wherein a sensor of the transducer housing is configured to measure one or more characteristics of the flow of exhaled or inhaled air passed to the transducer housing and to provide data of the flow of exhaled air passed to the transducer housing,
wherein the mouthpiece comprises a flow channel having a first orifice and a second orifice, the first orifice being configured for the user to blow exhaled air or to draw inhaled air into the mouthpiece, and the second orifice being configured for discharge from the mouthpiece or intake of the exhaled air or inhaled air,
wherein the transducer housing comprises an air passage having an inlet and an outlet, and, when the mouthpiece is attached to the transducer housing, the inlet is fluidly connected with the flow channel and the outlet is fluidly connected with the sensor of the transducer housing, said air passage being configured to pass at least part of the exhaled air or inhaled air from the flow channel to the sensor of the transducer housing,
wherein the mouthpiece further comprises a third orifice disposed in one side of the mouthpiece, and, when the mouthpiece is attached to the transducer housing, the inlet of the air passage is fluidly connected with the flow channel via the third orifice,
wherein the transducer housing comprises a pivot joint configured for pivotably attaching the mouthpiece, wherein the mouthpiece is releasable from the pivot joint, thereby enabling the mouthpiece to be detached from the transducer housing, and
wherein the air passage extends along and parallel with the pivot axis of the pivot joint.
