Systems and methods producing a customised patient respiratory interface are disclosed. Data representative of one or more landmark features of a head of a human is obtained. One or more landmark feature locations of the landmark features are identified based on the data. A set of manufacturing specifications for production of the patient respiratory interface component is determined based on the one or more landmark feature locations. The patient respiratory interface component is produced based on the set of manufacturing specifications.

An apparatus for delivery of a flow of gases to a user, such as a respiratory therapy apparatus, is provided. The apparatus may have first and second inlets for receiving supplementary gases flows, a blower to generate the gases flow to the user, and a controller. A valve and a sensor may be provided in the second inlet. The controller may be configured to detect the disconnection of a gases source from the second inlet, and to respond by operating the valve and/or triggering an alarm. The controller may be configured to determine whether a gases flow is being provided at one or both of the inlets, and to accordingly control an operational mode of the apparatus.

A breathing apparatus may include a heater configured to kill harmful organisms in air. The apparatus may include a vest, including a heating chamber disposed on the vest and a cooling chamber disposed on the vest. The heating chamber may include a heat source, and the heat source may heat air disposed within the heating chamber to a predetermined temperature. The heating chamber and the cooling chamber may be in fluid communication. The apparatus may include a breathing tube, including a first end and a second end. The first end may connect to the cooling chamber. The apparatus may include a breathing mask. The second end of the breathing tube may connect to the breathing mask. The cooling chamber and the breathing mask may be in fluid communication via the breathing tube.

Systems and related methods for delivering hot air to a respiratory tract of a user. The system includes a hot air source comprising a heater and a blower configured to produce a flow of hot air have a temperature of at least 150° F. The flow of hot air may have a relative humidity of less than 50-20%. The system also includes a user interface connected to the hot air source by a breathing tube. The user interface is configured to receive the flow of hot air from the hot air source and deliver the flow of hot air to the respiratory tract of the user.

A heat and moisture exchanger device comprising a housing containing a microcurrent-generating filter capable of generating a low level microcurrent. A microcurrent-generating filter can reduce the number of living or active microbes.

Systems for evaluating the respiratory function of an individual using forced oscillation technique (FOT) oscillometry include a blower controlled so as to apply FOT pressure oscillations on top of a low amplitude offset pressure. A controller continually adjusts the rotational speed of the blower to maintain a targeted time-varying pressure profile in the breathing air provided to the patient.

Systems and methods for generating MRI images of the lungs and/or airways of a subject using a medical grade gas mixture comprises between about 20-79% inert perfluorinated gas and oxygen gas. The images are generated using acquired .sup.19F magnetic resonance image (MRI) signal data associated with the perfluorinated gas and oxygen mixture.

Embodiments of the present invention provide systems and methods for delivering respiratory treatment to a patient. For example, a treatment system may include a mechanism for delivering a positive pressure breath to a patient, and one or more limb flow control assemblies which modulate gas flow to and from the patient. Exemplary treatment techniques are embodied in anesthesia machines, mechanical ventilators, and manual ventilators.

In accordance with the present invention, there is provided an adaptor or attachment which is suitable for integration into the patient circuit of a ventilation system, such as a non-invasive open ventilation system, is configured for attachment to any standard ventilation mask, and is outfitted with a jet pump which creates pressure and flow by facilitating the entrainment of ambient air. The adaptor comprises a base element and a nozzle element which are operatively coupled to each other. The base element further defines a throat and at least one entrainment port facilitating a path of fluid communication between the throat and ambient air. The nozzle element includes a jet nozzle, and a connector which is adapted to facilitate the fluid coupling of the nozzle element to a bi-lumen tube of the patient circuit. The connector includes both a delivery port and a sensing port. The jet nozzle and the delivery port collectively define a delivery line or lumen which fluidly communicates with the throat of the base element, and is placeable into fluid communication with the delivery lumen of the bi-lumen tube.

One embodiment of the present invention provides a multifunctional face mask system adapted to receive a nebulizer system, enabling a user to be treated by a nebulizer medication, while simultaneously providing a hygienic barrier between the user and their external environment via at least one filter component. The present invention further provides a multifunctional face mask system that is self-supporting, thereby enabling a user to wear the mask system in a portable manner. The present invention, in other embodiments, includes the bonding between at least one filter component and its corresponding filter window, to be produced by a selective mold behind injection molding process.
