The present specification is directed a method manufacturing a patient interface for treatment of sleep disordered breathing using air pressure by delivery of air to a patient's airway. The method includes locating a shell, a first sub section of a seal forming structure, and a first section of the seal forming structure in a tool. The first sub section includes a groove. The first section is constructed from a thermoformable material. The method further includes introducing a moulding material to the tool and overmolding the shell, the first sub section, and the first section. The moulded material forms a second sub section of the seal forming structure that connects the first sub section to the shell and fully encloses the first section within the groove.

Patient interface, seal forming structure and method of manufacturing of the same

A patient interface comprises a frame, a headgear, a manifold and two nasal prongs. The frame may be recessed from the face of the patient, and preferably from the manifold so that the manifold may deform or move with respect to the face of the patient. The manifold may be further configured to be compliant in the direction of engagement with the patient's face, such as in the anterior direction. These features may allow the manifold to engage with the face of the patient, such as the upper lip, without exerting a significant pressure which may lead to patient discomfort. The manifold may also be configured to be rotatable with respect to the frame, for example by a grip feature which may be configured to be held in one hand for rotation.

Patient interface

A patient interface includes a seal forming portion, a pad, and a cushion. The seal forming portion may have a base surface and a plurality of fibers fixed to and extending away from the base surface for contacting a patient's skin. The cushion may have at least along a portion of the circumference a first structure having an elongate section joined with at least one end section oriented substantially perpendicular or at an angle to the elongate section. A first end A of the elongate section may be connected or connectable to a frame member. The end section may be provided at an opposing second end B of the elongate section. The pad may have a resilient foam material layer with the seal forming portion. The pad may be adapted to be connected to the cushion.

Seal forming portion, pad and cushion for a patient interface and method of manufacturing

The present technology relates to a pad for forming a seal forming structure against a user's skin for use with a patient interface, the pad comprising, a base layer, a fibre layer comprising a plurality of fibers for contacting a patient's skin, and a connection layer for connecting the fibers to the base material, wherein the base layer and/or the fibre layer is/are adapted to act as a reservoir for substances. Furthermore, it relates to a set of pads, a kit and a patient interface.

Patient interface component

The present technology relates to a tub for a humidifier comprising a container made of a first material, a heating element, and a lining made of a second, preferably biocompatible, material different from the first material, wherein the container comprises a base and a side wall defining a reservoir for a supply of liquid to be evaporated, the heating element is provided on the base of the container, and the lining covers the heating element and a substantial portion of the inner surface of the side wall of the container.

Heating apparatus

A water reservoir for an apparatus for humidifying a flow of breathable gas includes a reservoir base including a cavity structured to hold a volume of liquid and a conductive portion provided to the base. The conductive portion is adapted to thermally engage with a heater plate to allow thermal transfer of heat from the heater plate to the volume of liquid. The conductive portion includes a thin film comprising a non-metallic material, and the thin film includes a wall thickness less than about 1 mm.

Humidifier reservoir

It is discloses a patient interface comprising a seal forming portion, a pad, and a cushion. The seal forming portion may comprise a base surface and a plurality of fibers fixed to and extending away from said base surface for contacting a patient's skin. The cushion may comprise at least along a portion of the circumference a first structure having an elongate section joined with at least one end section oriented substantially perpendicular or at an angle to the elongate section. A first end A of the elongate section may be connected or connectable to a frame member. The end section may be provided at an opposing second end B of the elongate section. The pad may comprise a resilient foam material layer with the seal forming portion. The pad may be adapted to be connected to the cushion.

The present invention relates to a tub configured to receive a volume of liquid for a humidifier, comprising at least one plastic component and at least one metal component, which together form a space for receiving said volume of liquid, wherein the at least one metal component and the at least one plastic component are attached to each other by means of a silicone seal. Furthermore, the invention relates to method for manufacturing a tub for a humidifier.

Tub for use in a humidifier

The present specification is directed to a seal forming structure for a patient interface for delivery of air to a patient's airway, wherein the seal forming structure comprises a first section of a thermoformable material and a second section of another material. The present specification is also directed to a patient interface comprising such a seal forming structure, wherein the patient interface further comprises a shell. The specification is also directed to methods for manufacturing such a patient interface.

A blower for a respiratory apparatus includes an impeller configured to rotate to pressurize the supply of gas. The impeller includes a shroud with a plurality of vanes extending from a surface of the shroud toward the gas inlet. Each vane radiates outwards from a hub in the shroud that is configured to receive a motor shaft. The outer diameter of the shroud varies between maximum portions with a maximum outer diameter and minimum portions with a minimum outer diameter. The maximum portions are located at the vanes and the minimum portions are located between the vanes. In addition, each vane has an intermediate point located a predetermined distance from the hub that marks the beginning of a curvature of the vane in the direction of the impeller's rotation. The curvature of the vane is located between the intermediate point and the radially outermost end of the vane.

Patient ventilation device including blower with scallopped shroud

The technology provides for a cushion assembly or a tool for forming the cushion assembly for a patient interface delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways. The cushion assembly has an inferior surface and a mask connection portion, and includes a pad arranged on the inferior surface for sealingly contacting a wearer's face in use.

Seal forming structure for a patient interface and a tool and method of manufacturing the seal forming structure

A respiratory apparatus for treating a patient with a respiratory disorder includes a blower configured to generate a supply of pressurized breathable gas. The blower includes a gas inlet and a gas outlet. The gas outlet is configured to deliver the generated supply of pressurized breathable gas to an outlet of the respiratory apparatus for delivery to the patient. The blower also includes an impeller configured to rotate to generate the supply of pressurized gas. The impeller has a single shroud with a plurality of blades extending from a surface of the shroud in an upstream direction relative to the direction of flow of the pressurized breathable gas. Each of the plurality of blades radiate outwards from a hub in the shroud. The hub is configured to receive a motor shaft. In addition, the outer diameter of the shroud varies between maximum portions with a maximum outer diameter and minimum portions with a minimum outer diameter.
