Respiratory assistance device suitable for Auto CPAP respiratory therapy. The respiratory assistance device includes: a blower device including a blower configured to generate pressurized air; an operation device including an operation interface configured to control the blower; a wireless or wired communication arrangement configured to connect the blower device and the operation device; an attachment part configured to be attached to a head of a patient so as to supply the pressurized air to an airway of the patient; and an air tube through which the pressurized air is introduced into the attachment part from the blower device. The blower device is accommodated in a blower device casing, and the operation device is accommodated in an operation device casing separate from the blower device casing.

A positive air pressure delivery device includes a housing having an inhalation inlet, an inhalation outlet, and an interior cavity in fluid communication with the inhalation inlet and outlet. A pressurized fluid inlet includes an outlet orifice in fluid communication with the interior cavity between the inhalation inlet and outlet. A sound reducer baffle has a convex dome surface positioned downstream of and facing the outlet orifice in a spaced apart relationship therewith. One embodiment of the housings includes a body, an end cap and a baffle insert. In various embodiments, the positive air pressure delivery device may be used in combination with other therapy devices, including an OPEP and pressure indicator. A kit and method of using the device are also provided.

Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.

A patient interface assembly includes a cushion assembly, and air delivery tube, and a connector assembly. The cushion assembly includes a flexible cushion including a base and a pair of nasal pillows that extend from the base and a frame that is more rigid than the flexible cushion. The connector assembly connects the air delivery tube to the cushion assembly and includes and elbow with a second end with a part spherical ball shape and a gas washout vent with a plurality of vent openings. The connector assembly also includes an elbow connector positioned in the frame. The elbow connector forms a part spherical socket shape that engages the part spherical ball shape of the elbow. The elbow connector includes an anchoring flange, which is configured to secure the flexible cushion to the elbow connector by way of the anchoring flange being inserted into the flexible cushion through a central opening in the flexible cushion.

An oxygen concentrator 100 apparatus and a method thereof implement operations control to efficiently release oxygen enriched gas to reduce potential waste. The control methodology may include generating a profile such as a minimum inhalation flow profile of the user. The profile may be based on a size parameter of the user. The method may determine one or more control parameters characterizing a bolus of oxygen enriched gas based on the generated flow profile. The control methodology may then generate a bolus release control signal, such as for a supply valve, according to the determined one or more control parameters. The oxygen concentrator may then, with the control signal, release and deliver a bolus of oxygen enriched gas for a user such as for reducing waste.

A micro, single piece, tubeless, cordless, directly inserted oral, nasal or hybrid sleep apnea treatment/anti-snoring device having controlled positive air-flow using a vibrationally isolated micro-blower to maintain an individual's upper airway unobstructed (pharynx area) with or without lower jaw, mandibular advancement is disclosed.

An apparatus for providing a pressurised flow of breathable gas to the airways of a patient includes a pivotable outlet port structured and arranged to connect to an air delivery tube configured to pass the pressurised flow of breathable gas to a patient interface. The pivotable outlet port is able to pivot about at least one axis.

A head-mountable flow generator is configured to deliver a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to a patient interface in communication with an entrance to a patient's airways including at least an entrance of the patient's nares, while the patient is sleeping, to ameliorate sleep disordered breathing. The flow generator includes a motor, an impeller assembly and housing that encases the motor and the impeller assembly. The housing is configured to be mounted on the patient's head and comprises an inlet to receive the flow of breathable gas and a pair of opposing outlets to deliver the flow of breathable gas. In addition, the impeller assembly is configured to pressurize the flow of breathable gas received from the inlet, and the housing is configured to convey the pressurized flow of breathable gas through both outlets.

Various characteristics of a gas flow can be sensed at the end of a respiratory conduit near the patient interface using a sensing module. The sensing module can be removable from the patient end of the respiratory conduit for ease of use and ease of cleaning. The sensor module can transmit sensor data over the same wires used to heat the respiratory conduit.

Several embodiments of exhalation ports for use respiratory systems are described. Some of the embodiments provide an elongate body defining a lumen through which gases may flow. A plurality of tapered openings is arranged on a portion of the elongate body and configured to vent gases. A shroud extends from the elongate body and surrounds one or more of the plurality of tapered openings. The exhalation port is arranged to removably connect in-line with a circuit for delivering gases to a patient.
