A humidifier is for an airway pressure support system for delivering a humidified flow of breathing gas to an airway of a patient. The humidifier includes a water chamber, a filter, a filtration meter, a conduit, a nozzle, and a heater plate. The filter has a housing structured to house a filtration medium therein and having an inlet fluidly connected with the water chamber and an outlet. The filtration meter includes an inlet fluidly connected to the outlet of the filter, an outlet, a body portion extending between the inlet and the outlet which is structured to convey water from the inlet of the filtration meter to the outlet of the filtration meter, and a mechanism located in the body portion which is structured to measure filtration data of the water conveyed through the body portion.

A humidifier uses a field of hydrophobic, nanotubes (e.g., vertically aligned carbon nanotubes) to humidify a gas. Voids in the field form liquid flow channels that are wide enough for liquid water to pass through. The nanotubes are spaced close enough to each other to prevent the water from escaping the channels. Water in the channels is absorbed by gas that flows and/or diffuses between the nanotubes. Humidity levels in the gas can be measured and controlled to a desired level by controlling the rate of flow of gas through the humidifier, controlling heating of the gas, and/or adjusting the total area of molecular transfer from the water to the gas by providing multiple banks of nanotubes and controlling the number of banks through which the gas flows.

The design and structure of a fully automatic oxygen therapy apparatus is exhibited in this disclosure. The apparatus integrates a MEMS mass flow meter, an oximeter, a proportional valve and a smart liquid bottle. The control unit of the apparatus is embedded with a wireless communication device and powered by a battery pack. This apparatus is designed to replace the mechanical oxygen rotameter used in today's hospital or homecare oxygen therapy applications. With a set recipe or parameters locally or remotely, the disclosed apparatus can perform a fully automatic oxygen therapy for recovering the blood oxygen level of patient, without the frequent attention of the therapy administrator, and especially it significantly reduces the possibility of cross infection to the administrator during the attendance of the oxygen therapy process. The therapy process data are relayed to local users as well as a designated cloud or data center. This disclosure will be beneficial for both medical staffs and patient.

A bypass adaptor for a respiratory assistance system including an inlet connector configured to connect to a gases source outlet and defining a first gases passageway with a first axis and an outlet connector configured to connect to an inspiratory conduit connector and defining a second gases passageway with a second axis, the second gases passageway being fluidly connected to the first gases passageway, the inspiratory conduit connector being incompatible with direct connection to the gases source outlet, wherein the first axis is separated from the second axis by an angle that allows the inspiratory conduit connector to be connected via the bypass adaptor to the gases source outlet in a space smaller than the length of the inspiratory conduit connector. Also provided are a port cap assembly and a humidifying apparatus including the port cap assembly, wherein the port cap assembly provides for improved assembly and/or usability.

The invention relates to a respiratory device (10) for the artificial respiration of a patient (12), comprising: —a respiration gas source assembly (15, 62), —a flow-changing device (16), —a humidifier device (38) which is designed to increase the value of the absolute humidity of the inspiratory respiration gas flow (AF), said humidifier device (38) having a liquid store (40) and an evaporation device (76) with a variable output for this purpose, —a respiration gas line assembly (30), —a proximal temperature sensor (48) which detects the temperature of the respiration gas flow (AF) in the proximal longitudinal end region (30a) of the respiration gas line assembly (30), —a humidity sensor assembly (66) which directly or indirectly detects the absolute humidity of the inspiratory respiration gas flow (AF), —a flow sensor (44), and —a controller (18) which is designed to control the operational output of the evaporation device (76)

A breathing assistance apparatus 10 has a housing 100 with a recess 108. A guard 200 is mounted to the housing 10, the guard having a base 201 and a barrier 251. At least part of the base 201 is flexible. The barrier 251 is movable between a covering position in which the barrier 251 partly covers the recess 108 and an access position in which the recess 108 is less covered or is uncovered by the barrier 251. Said at least part of the base 201 is configured to flex as the barrier 251 is moved between the covering position and the access position.

This disclosure describes systems and methods for humidifying ventilator delivered breathing gases. These systems and methods utilize a hollow cone atomizer (e.g., a pressure swirl atomizer) and/or a heating element associated with a heating circuit and/or a heating tube. In some aspect, the systems and methods utilize received flow, temperature, and/or humidity information to determine an amount of water to add to breathing gases to reach a desired humidity of the breathing gases delivered to the patient. In further aspects, the humidification system can serve as a nebulization system for delivering nebulized medicine.

A nightstand designed to support and contain various CPAP machines and associated CPAP equipment including air tubing, cleaning devices and distilled water storage. Separate drawers and compartments are provided to house the CPAP machine, CPAP cleaning device, and water supply containers. Various openings are designed to increase utility and convenience in the operation and storage of CPAP devices and associated equipment. A pump may be provided to transfer water from water supply containers to the CPAP machine reservoir. The CPAP nightstand is designed to be located at bedside and provides easy access to the CPAP machine and its ancillary devices while keeping all equipment in dedicated drawers. Each dedicated drawer provides openings to allow passage of air tubing, water hoses and power cords. The CPAP nightstand also has generic drawers for additional storage.

A respiratory humidification system includes a humidifier that is capable of electronic communication with one or more other components of the system thereby permitting transfer of data or control signals between the humidifier and other components of the system. In some systems, a flow generator, such as a ventilator, is provided to supply a flow of breathing gas. The humidifier and the flow generator are capable of electronic communication with one another. In some arrangements, an operating mode or parameter of the humidifier to be set or confirmed by the flow generator, either automatically or manually through a user interface of the flow generator. The humidifier can also utilize data provided by the flow generator or other system component, such as an incubator, to set or confirm an operating mode or parameter of the humidifier. In some arrangements, a user interface of the humidifier can display data from another system component, such as a nebulizer or pulse oximeter.

Methods and apparatus for administering oxygen therapy, and particularly high-flow oxygen therapy is disclosed herein. A respiratory monitoring system may non-invasively determine average peak inspiratory flow rate of a patient based on biofeedback response received from the patient. Medical air, oxygen, or a combination of both may be delivered to the patient at a flow rate equal to greater than the determined average peak inspiratory flow rate of the patient to meet or exceed inspiratory demand of the patient. Fraction of oxygen inspired by the patient may be determined based on the average peak inspiratory flow rate and may be adjusted through high-flow oxygen therapy meeting inspiratory demand to prevent entrainment of ambient air or through low-flow oxygen therapy by accounting for entrainment of ambient air based on the average peak inspiratory flow rate to address medical needs of the patient.
