A gases delivery system for medical use is disclosed that has a container configured to house a metal-organic framework material within at least one section of the container. An activation mechanism may be associated with the container. The metal-organic framework material may contain one or more substances such that the one or more substances may be released from the metal-organic framework material when energy is applied to the container via the activation mechanism. The activation mechanism may be a heating mechanism. One or more containers housing metal-organic framework materials may be used in a gases recirculation system.

An expiratory limb is provided that is configured to remove humidified gases from a patient and configured to provide improved drying performance by providing a tailored temperature profile along the limb. Limbs for providing humidified gases to and/or removing humidified gases from a patient are also provided, the limbs having improved gas residence time at constant volumetric flow rate. The improved residence time can be achieved by providing a limb comprising multiple lumens.

This invention relates to a respiratory therapy system comprising a first patient interface for delivery of a flow of gas to a patient, and a second patient interface for delivery of a flow of gas to the patient, or devices or interfaces for use in such systems.

A system may include an external device and an inhaler. The external device may include a processor, a communication circuit, and memory. The inhaler may include a mouthpiece, medicament, a mechanical dose counter, and an electronics module comprising a processor and a communication circuit. The electronics module may record a dosing event when the inhaler is actuated, such as when the mouthpiece cover is opened, and send a signal indicating the dosing event to the external device. The external device may receive a mechanical dose reading of the mechanical dose counter, determine an electronic dose reading based on the signal indicating the dosing event, determine that a discrepancy between the mechanical dose reading and the electronic dose reading exceeds a threshold, and notify the user of the discrepancy, for example, by providing a notification to the user by way of a mobile application residing on the external device.

Systems and methods for nitric oxide (NO) generation systems are provided. In some embodiments, an NO generation system comprises at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas. The electrodes have elongated surfaces such that a plasma produced is carried by the flow of the reactant gas and glides along the elongated surfaces from a first end towards a second end of the electrode pair. A controller is configured to regulate the amount of NO in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller. The one or more parameters include information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which the product gas flows.

Systems and methods for generating nitric oxide are disclosed. A nitic oxide (NO) generation system includes at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas; and a controller configured to regulate the amount of nitric oxide in the product gas produced by the at least one pair of electrodes by utilizing duty cycle values of plasma pulses selected from a plurality of discrete duty cycles to produce a target rate of NO production based on an average of discrete production rates associated with each of the plurality of discrete duty cycles.

Architectures for production of nitric oxide (NO) include systems and methods for generating NO having one or more plasma chambers configured to ionize a reactant gas to generate a plasma for producing a product gas containing NO using a flow of the reactant gas through one or more plasma chambers; a controller configured to regulate the amount of nitric oxide in the product gas using one or more parameters as an input to the controller, one or more parameters including information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which product gas flows; and a flow divider configured to divide a product gas flow from the plasma chamber into a first product gas flow to provide a variable flow to a patient inspiratory flow and a second product gas flow.

A system for providing continuous positive air pressure therapy is provided. The system includes a flow generator, a sensor, and a computing device. The computing device is configured to control operation of the flow generator based on sensor data. The computing device is further configured to display, on a display device, one or more questions relating to demographic and/or subjective feedback; responsive to displaying the one or more questions, receive one or more inputs indicating answers to the one or more questions; transmit the answers to a remote processing system; receive, from the remote processing system, settings determined based on the transmitted answers; and adjust control settings of the system based on the received settings.
