Abstract: A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurised gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.

Abstract: A system and method is provided to allow access to centralised patient data captured from a medical device across an open network to a third party. The system and method receives the request based upon patient-specific information, checks the request and allows access if the request matches stored information.

Abstract: The present disclosure provides to graphical user interfaces for controlling a flow therapy apparatus. The graphical user interface can provide a display of flow therapy treatment information and indicators of a patient's health. The graphical user interface can be configured to display the information associated with the patient on one or more user interface screens.

Abstract: A breathing assistance apparatus has a housing with a recess. A guard is mounted to the housing, the guard having a base and a barrier. At least part of the base is flexible. The barrier is movable between a covering position in which the barrier partly covers the recess and an access position in which the recess is less covered or is uncovered by the barrier. Said at least part of the base is configured to flex as the barrier is moved between the covering position and the access position.

Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, incorrect connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if reverse flow conditions or other error conditions exist. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The methods can be implemented at the humidifier side, at the gases source side, or both.

Abstract: A respiratory mask system is provided. The respiratory mask system has a patient interface that is secured to a user's head by a headgear. The patient interface comprises a seal, a frame and a gas delivery conduit. The frame is configured to secure the seal and gas delivery conduit together. The frame comprises a recessed channel and/or headgear retaining features configured to connect the headgear to the patient interface. The frame can include an inlet collar that connects to a gas delivery conduit. The inlet collar can include bias flow holes. The headgear comprises a top strap, a pair of side arms, a yoke and a rear strap. The yoke is configured to connect to the recessed channel of the frame. The top strap, side arms and yoke form an integrally formed closed loop. The top strap can include two portions adjustably connected to each other.

Abstract: This invention relates to a medical tube comprises an elongate conduit having a first opening, a second opening, a longitudinal axis, a lumen extending between the first opening and the second opening along the longitudinal axis, and a corrugated wall, formed from an extruded material, extending between the first opening and the second opening and surrounding the lumen. The wall is stiffer in a first length of the conduit adjacent the first opening than in a second length of the conduit adjacent the second opening. The variable stiffness of the tube wall can improve the thermal profile of the tube as well as improve drain-back of condensation into a humidifier providing humidified gas to the tube.

Abstract: A wye connector has a patient coupling end. The patient coupling end has a first connector surface and a second connector surface. The first connector surface has a first diameter at an axial location along the patient coupling end. The second connector surface has a second diameter at the same axial location along the patient coupling end. The first diameter is larger than the second diameter. The second connector surface projects axially outward beyond the first connector surface.

Abstract: An interface assembly includes an interface, such as a mask, that is secured to a head using a headgear assembly. The headgear assembly can include at least one halo portion and a plurality of straps. The headgear assembly can include both a front halo portion and a rear halo portion. In some arrangements, the headgear and mask define an adjustable closed loop. In some arrangements, the headgear can include one or more rigid portions that contact the user's face to at least partially isolate a seal of the mask from tightening forces applied to the headgear. In some arrangements, the mask is an oral-nasal mask and the headgear applies a force to the mask comprising an upward force component. In some arrangements, the headgear can be contoured to the user's head.

Abstract: A medical tube comprises a tail to connect an embedded wire to an electrical component. The tail may comprise a flattened portion and an exposed portion to facilitate attachment of the medical tube to an electrical component. The tail may comprise a second flattened portion. One or more wires, such as a heater wire or a sensor wire, may be embedded in the medical tube. The medical tube may comprise a connector that comprises a printed circuit board to which the one or more wires is attached. The connector may comprise features to support the printed circuit board, aid in assembly of the one or more wires to the connector, and protect electrical components against liquid ingress.

Abstract: A patient interface, such as a nasal cannula, including a body to be positioned upon a user (preferably such as a user's face), the body including at least one (and preferably a pair of) nasal prong(s), the or each nasal prong including a lumen capable of being fluidly connected thereto for fluid communication with a supply of breathable gas, the or each nasal prong to be in a configuration either inserted into, or to direct a flow of gas toward, a nare or the nares of the user's nose, wherein the body includes at least one element responsive to force(s) or movement(s), or both, experienced by at least a first region of the patient interface.

Abstract: The invention relates to systems for securing a tube (e.g. feeding tube) and/or a patient interface or a dermal patch to a user. One embodiment comprises a holder, an interface side of the holder attachable to the patient interface or the dermal patch for securing a feeding tube to the patient interface or the patch, the holder comprising at least a first channel or recess for receiving the feeding tube to couple the feeding tube to the patient interface. Another embodiment comprises a patient interface itself comprising a backing for positioning on a patient's face, a dermal patch having a patient side and an interface side, the patient side of the patch attachable to the user, the patch comprising at least a first flap portion attachable to the tube for affixing the tube to the patch, a two-part releasable connection arrangement for releasably securing the patient interface to the patch.

Abstract: Some embodiments provide for an inspiratory limb for a breathing circuit that includes a first segment that comprises a first heater wire circuit and a second segment that comprises a second heater wire circuit. The inspiratory limb can include an intermediate connector that includes a connection circuit that electrically couples the first heater wire circuit to the second heater wire circuit. The inspiratory limb can be configured to operate in two modes wherein, in a first mode, electrical power passes through the first electrical connection to provide power to the first heater wire circuit without providing power to the second heater wire circuit, and in a second mode, electrical power pass through the first electrical connection to provide power to both the first heater wire circuit and the second heater wire circuit.

Abstract: High flow therapy is used to treat Cheyne-Stokes respiration and other types of periodic respiration disorders by periodic application of high flow therapy, adjustment of high flow therapy flow rates and/or periodic additions of CO2 or O2 into the air flow provided to the patient.
