Abstract: Respiratory therapy apparatus and methods to deliver one or more positive airway pressure therapies are disclosed. The respiratory apparatus includes a flow generator having a first interlock and at least one module that includes a second interlock. The first interlock and the second interlock releasably engagable with one another. The flow generator and the module may be secured in a stacked vertical configuration.

Abstract: The present invention provides an apparatus and methods for the administration of positive airway pressure therapies. The apparatus can include a housing, a blower and a mask. The housing is configured to be stably secured on the head of a patient. The blower is secured relative to the housing. A mask in fluid communication with the blower is configured to communicate pressurized air produced at least in part by the blower to the airways of a user.

Abstract: The present invention provides an apparatus for the supply of air for the treatment of sleep apnea. The apparatus of the present invention includes a motor and a fan unit. The motor and fan unit are enclosed in an inner case of flexible foam plastics material. The inner case is configured to contain the motor and the fan unit, and the inner case 48 is generally biased against the motor and the fan unit. The inner case is, in turn, contained within an intermediate case made of rigid material. The intermediate case conforms to and is substantially filled by the inner case such that the inner case is generally biased against the intermediate case. Finally, the intermediate case is contained within an outer case of rigid material. The outer case surrounds the intermediate case. The outer case is generally set apart from the intermediate case so that there is a gap between the intermediate case and the outer case.
