Abstract: The invention relates to an equine inhalation mask, comprising at least one valveless combined inhalation and exhalation conduit, into which inhalant sources comprising respiration control elements and an energy supply that does not require supply lines are interchangeably integrated. A filter system is mounted on the outer end of the inhalation and exhalation conduit facing away from the head of the horse. Said system and the fact that the mask is effectively sealed when on the head of the horse prevent any escape of the aerosol into the environment, thus permitting a reliable inhalation therapy lasting several minutes under normal respiratory conditions.

Abstract: A combination mouthpiece for inhalation therapy devices, having a body (1) defining an aerosol duct (2) through which, in use, a stream of air carrying an aerosolized drug is supplied to a patient during inspiration, an inlet hole (4) through the body for receiving in a releasable and secure manner an oxygen tube adapter (5), characterised by at least one partition (6) within the body (1) defining at least one oxygen duct (3), the oxygen duct being in a form such that it extends generally parallel with the aerosol duct (2) and has a flow cross-section sized in order to guide a suitably large oxygen stream from the oxygen tube adapter (5) through the inlet hole (4) to the patient.
