The present disclosure relates to a method for identifying a user interface. Flow data associated with air flowing in a respiratory therapy system is received. Acoustic data associated with the respiratory therapy system is received. The received flow data and the received acoustic data are analyzed. Based at least in part on the analysis, a mask type for the user interface is determined.

A nebulizer assembly for a respiratory device is provided having a housing defining a chamber. The housing also has a nebulizer port configured to receive a nebulizer to discharge atomized medication into the chamber. An outlet of a handle is coupled to the inlet of the housing. A hose is coupled to an inlet of the handle. A patient interface is coupled to the outlet of the housing. Air flows from the hose to the patient interface via the handle and the housing. The air mixes with the atomized medication within the chamber.

A patient interface including a seal-forming structure with an elastomeric membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The elastomeric membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The elastomeric membrane is molded to include a three-dimensional shape that has multiple curvatures. The at least one hole includes an arch on a lateral side of the at least one hole, and is in a relaxed state before use. The arch is configured to move to a substantially taut state during use.

The Non stretch, loop fastening NEO-prene, used in my various products, for our sick & premature neonate's, allows more effective & secure CPAP (continuous positive airway pressure) therapy. It also decreases the risks of pressure injury like skin pressure areas, burns, nasal septal damage & deformation of the preterm head (“Prem Head”). It helps prevent loss of CPAP air pressure (“pop off”), as well as decrease retinal damage of the eyes, & inaccurate oxygen saturation readings leading to poor oxygen management in neonates. It also contributes to developmental care of the neonate by limiting damaging loud noises & bright lights, which have detrimental neurological consequences for neonatal development.

A patient interface includes a sealing arrangement adapted to provide an effective seal with the patient's nose, an inlet conduit arrangement adapted to deliver breathable gas to the sealing arrangement, and a cover that substantially encloses the sealing arrangement and/or the inlet conduit arrangement.

A patient interface includes a shell with a central opening configured to receive the pressurized flow of air, a foam cushion, and an elastomeric support portion that is attached to the shell, supports the foam cushion, and forms at least part of a chamber together with the shell and the foam cushion. The elastomeric support portion includes a side wall that forms a continuous perimeter around the chamber and a resiliently flexible lip that supports the foam cushion and extends from the side wall toward an interior of the chamber. The resiliently flexible lip has an outer perimeter that is anchored to the side wall and an unsupported inner perimeter. The foam cushion overhangs the inner perimeter of the resiliently flexible lip, and the shell is more rigid than the elastomeric support portion. In addition, the foam cushion is configured to directly contact and engage a portion of the patient's skin in use.

An elbow assembly for use in a respiratory mask, which includes an elbow, an inlet port, an exhaust port, and a baffle separating the inlet port from the exhaust port. A mask assembly includes a cushion comprising at least one gusset and an aperture for connection to the elbow assembly.

A patient interface device includes a support structure, a pivot arm pivotably coupled to the support structure and structured to pivot about an axis, a patient coupling member, such as a mask or a forehead support, coupled to the pivot arm, and a cam wheel rotateably coupled to the support structure and engaging the pivot arm, wherein rotation of the cam wheel relative to the support structure and the pivot arm causes the pivot arm to pivot about the axis and the patient coupling member to move either forward or backward along a path of movement. Also, an alternative patient interface device includes a cam wheel rotatable about a cushion member that changes a position of a main body portion of the cushion member relative to a headgear frame member of the patient interface device.

A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.
