The disclosed systems and methods provide a printed electronics breath indicator that may be directly printed or molded onto a manufactured breathing device, or separately attached to an existing breathing device. The printed electronics breath indicator may include an electroluminescent indicator, a sensor, and a processor. The processor may be configured to receive sensor data from the sensor, the sensor data including detected carbon dioxide (CO2) or oxygen (O2) levels. The processor may be further configured to determine a current breathing state of the patient based on the received sensor data. The processor may be further configured to cause the electroluminescent indicator to generate a visual representation according to the determined current breathing state of the patient. The visual representation may comprise a variable visual representation that displays one or more visual parameters that are proportional to the detected CO2 or O2 levels.

A patient interface kit to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to a patients airways including at least the entrance of a patients nares while the patient is sleeping. The patient interface comprising: a nasal cushion having a nasal cushion opening; a mouth cushion having a mouth cushion opening, the mouth cushion including a flexible joint, positioned above the mouth opening, to selectively connect the nasal cushion to the mouth cushion; and a positioning and stabilizing structure to provide a force to hold the nasal and/or mouth seal-forming structures in a therapeutically effective position on a patient's head, the positioning an stabilizing structure including a nasal headgear including upper straps or conduits and a mouth headgear including lower straps, the mouth headgear being selectively connected to the nasal headgear.

A patient interface including a seal-forming structure with a textile 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 textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

Discloses is a micro-pump that includes a pump body having a compartmentalized pump chamber, with plural inlet and outlet ports and a plurality of membranes disposed in the pump chamber to provide compartments. The membranes are anchored between opposing walls of the pump body and carry electrodes disposed on opposing surfaces of the membranes and walls of the pump body. Also discloses are applications of the micro-pump including as a heat remover and a self-contained continuous positive airway pressure breathing device.

Nasal cannulas are described herein. The nasal cannula (110) includes a cannula housing (112), a reservoir (160), a nebulizer channel (154), and a gas channel (120). The cannula housing includes at least one nasal extension (116) extending from the cannula housing, wherein the at least one nasal extension is configured to be disposed within a patient's nares. The reservoir includes a reservoir volume configured to dispense a medicament. The nebulizer channel is in fluid communication with the reservoir volume and the at least one nasal extension. The gas channel is configured to direct a gas flow toward the at least one nasal extension through the nebulizer channel, drawing a portion of the medicament from the reservoir through the nebulizer channel with the gas flow toward the at least one nasal extension.

A harness for a patient interface which comprises, at least in some regions, an eyeglass tunnel which is configured and designed to at least partially receive at least one eyeglass arm.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient includes a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the respiratory gas is controlled by a microprocessor, a mixing area for mixing a first gas and a second gas in the respiratory gas flow pathway, a humidification area downstream of the mixing area and configured for humidifying respiratory gas in the respiratory gas flow pathway, and a heated delivery conduit for minimizing condensation of humidified respiratory gas.

A patient interface device includes a frame member and a cushion having a main body, a sealing portion, and first and second posts extending from the main body. The frame member defines a first orifice and a second orifice. The first post of the cushion is rotatably received within the first orifice and the second post is rotatably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.

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.

A respiration assistance device includes a nasal respiration assisting section for supplying a gas to the nasal cavity of a living body. The nasal respiration assisting section includes: a first gas supplying portion which supplies a gas below one of the nostrils of the living body; a second gas supplying portion which supplies the gas below the other nostril of the living body; a first tube connecting portion to which a tube for supplying the gas to the first gas supplying portion is connectable; and a second tube connecting portion to which a tube for supplying the gas to the second gas supplying portion is connectable.
