20230139237 · 2023-05-04 ·

Various implementations include methods of identifying data for producing a user-customized mask, systems for producing the same, a user customized mask, and an elongated support. To produce the mask or elongated support, 3D-data is received that defines the contour and dimensions of at least a portion of user's face. The 3D-data is determined by analyzing vector data associated with an area around the nose and mouth of the user, for example. A contact area(s) and a face contacting surface within the contact area are identified on the portion of the face of the user based on the 3D-data. And, structure-data based on the 3D-data and the identified contact area is provided for designing and producing a mask contacting surface. The mask contacting surface causes a portion of the mask to match the contour of the face contacting surface of the user.

ADJUSTABLE TENSION DEVICE FOR CPAP MASK

A cushion tension assembly for a respiratory interface device is provided. Cushion tension assembly includes an adjustment assembly and a number of tension members. Each tension member is operatively coupled to the adjustment assembly and is operatively coupled to the cushion body. In this configuration, the adjustment assembly is structured to move cushion body between a first configuration in which the cushion body provides a generally continuous seal, and a second configuration in which the cushion body provides a more complete seal.

RESPIRATORY ASSEMBLY

A respiratory assembly is provided. The assembly includes a base engaged with at least one connector and in fluid communication with a hose or fluid source for allowing the gaseous flowthrough between the at least one connector, the base and the hose or fluid source. The assembly further includes a pair of sockets engaged with the at least one connector, and a pair of posts, each post selectively engageable with at least one of the pair of sockets. Each post includes a flange that defines an opening therethrough, the openings in fluid communication with each corresponding socket of the pair of sockets. Each post further includes an adhesive adhered to each flange and configured for sealably engaging a patient's nare.

AUTO-FIT MASK

Devices and systems with methods for detecting a sealing condition between a patient interface and a patient, and adjusting the patient interface to maintain the patient interface in sealing contact with the patient. The patient interface may include a sealing structure to form a seal on the patient, and a positioning structure to secure the sealing structure to the patient. The patient interface may include a sensor coupled to the sealing structure. A processor determines the sealing condition between the sealing structure and the patient based on a signal from the sensor, and adjusts at least one of the sealing structure and the positioning structure to maintain the sealing structure in sealing contact with the patient. A prediction system predicts a leak between the sealing structure and the patient based on the sensor signal. A learning system learns how to fit the sealing structure to the patient to form a seal.

SYSTEMS AND METHODS FOR IDENTIFYING A USER INTERFACE

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.

TEXTILE SEAL-FORMING STRUCTURE WITH MULTIPLE CURVATURES

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.

Oxygen masks

The present disclosure relates to an oxygen mask comprising: a mask body defining a cavity configured to be positioned over the mouth and nose of a patient, an oxygen port formed on the upper half of the mask body, an annular aperture formed on the mask body, and at least one vent port formed on the mask body, wherein each vent port is formed on the bottom half of the mask body in a manner that patient's exhaled gases are directed towards the vent port.

HEADGEAR FOR A PATIENT INTERFACE
20230181859 · 2023-06-15 ·

A headgear for a patient interface, such as a respiratory interface, includes a plurality of panels which are lapped against each other. The panels define lapped parts of the headgear where panels overlap and/or underlap each other, and non-lapped parts of the headgear where a panel or panels are not lapped by another panel. The panels at the lapped regions are bonded to each other by an adhesive, such as a hot-melt adhesive. By combining panels having different properties, interfaces between panels having different lapping configurations, and by controlling the properties such as extensibility and stiffness of the adhesive when set a headgear may be provided location-specific features and properties.

Mask and components thereof

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.

Mask assembly

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.
