An inhalation device which entrains air to modify a source gas, such as pure oxygen, down to different selected levels of lower gas concentrations, with a high total gas flow being achieved for inhalation. The inhalation device allows eating and suctioning without interference while maintaining a constant uninterrupted gas supply at high volumes. The inhalation device is adapted for disposal adjacent to the nose and mouth of a person, and includes a nose hood connected to a chamber. The chamber has a central portion defining a longitudinal axis orientated perpendicular to the nose hood and also defining an opening aligned with and facing the nose in a configuration such that gas is inhalable from the central portion to the nose without the gas directly impacting the breathing orifices of a patient wearing the device.

A mask for supplying gas under pressure to the nasal airway of an infant human includes a manifold for supplying air to an aperture in the mask. A shaped membrane structure formed from a thin walled membrane defines an enclosure for receiving at least the nares of an infant human nose and a generally trapezoidal aperture adapted to fit around the nasal area of the infant human. Part of the membrane around the aperture is sufficiently flexible to mould to the shape of the infant human's nasal area or is contoured to generally match the contours around that nasal area whilst the membrane structure itself has sufficient rigidity to support the weight of the backing plate without collapsing. The provision of a generally trapezoidal rather than the generally triangular apertures for fitting around the nares provides a substantially improved fit when the mask is used with infants. The moulding or contouring of the membrane structure around the aperture to match the shape of the infant's facial contours around the nasal area including the provision of a generally planar portion surrounding the aperture is also important in ensuring a comfortable fit and an effective seal. The mask is entirely formed from a flexible elastomeric material for reason of comfort and function.
