An integrated respiratory pressure therapy device and humidifier for pressurising and humidifying breathable air to treat a respiratory disorder in a patient, includes a blower configured to pressurise the breathable air; a water reservoir configured to hold a volume of water to be used for humidification of the breathable air, the water reservoir comprising a water reservoir base, a water reservoir lid connected to the water reservoir base, and a compliant portion. The compliant portion is constructed from an elastomeric material and configured to seal between the water reservoir base and the water reservoir lid. A water reservoir dock forms a cavity configured to partially receive the water reservoir. The water reservoir lid includes a protrusion and the water reservoir dock includes a recess configured to releasably engage one another to secure the water reservoir to the water reservoir dock.

Methods and apparatus involve generation of an anti-infection therapy. The method/apparatus may include a controller controlling setting of a respiratory flow therapy device for the therapy. The controller may compute a target flow rate profile for a patient using a margin function, such that the target flow rate profile, according to the margin function, exceeds a minimum inspiratory flow rate profile of the patient's inspiration. The controller may control setting the respiratory flow therapy device to generate a flow of air to a patient interface according to the target flow rate profile, where the generation may be in synchrony with a sensed parameter that is indicative of a breathing cycle of the patient.

An anesthesia ventilator, for the automated ventilation of a patient, includes an expiratory port and an inspiratory port for connecting a patient ventilation tube for a breathing gas, a breathing gas delivery unit, a breathing gas volume flow sensor, a breathing gas sensor for detecting a carbon dioxide concentration, a pressure sensor for detecting a pressure of the breathing gas, and a computer. The computer is configured to actuate the breathing gas delivery unit in a first mode of operation as a function of a preset ventilation rate, of the detected pressure and of a preset desired pressure value. The computer is configured to detect the presence of a desired operating state concerning the automated ventilation on the basis of the detected volume flow and of the detected carbon dioxide concentration and to make possible a transition to a second mode of operation in case of detection.

An emergency respirator ventilator that comprising an air cylinder and piston/piston rod for compressing an air bag to transmit air to a patient, e.g., during situations where fully equipped ventilators are not immediately available.

An emergency ventilation system ventilates a patient and includes a chamber housing defining a breathing chamber; a piston; and a motor operably connected to the piston. The motor applies an exhalation force to move the piston in an exhalation direction applies an inhalation force to move the piston in an inhalation direction. The piston increases air in the breathing chamber as the exhalation force is applied and decreases air in the breathing chamber as the inhalation force is applied. An exhalation check valve allows airflow from the air source to the breathing chamber and not to allow airflow from the breathing chamber to the air source as the inhalation force is applied. An inhalation check valve allows airflow from the breathing chamber to the air output and not to allow airflow from the air output to the breathing chamber as the exhalation force is applied.

A system (1000) for a feeding of substances to a patient (30) with ventilation and oxygenation of the patient. The system (1000) includes a ventilation system (1), an oxygenation system (2), a breathing gas dispensing path (3), a purge gas dispensing path (4), a breathing gas connection system (5), an oxygenation connection system (6), a dispensing system (7), a switching unit (8), and at least one control unit (9). The switching unit (8) is configured for a distribution or splitting of a quantity of a drug or anesthetic active ingredient, which quantity was dispensed into a gas mixture by means of the dispensing system (7), between the ventilation system (1) and the oxygenation system (2). The at least one control unit (9) is configured to control the switching unit (8).

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.

One or more sensors are configured for detection of characteristics of moving objects and living subjects for human identification or authentication. One or more processors, such as in a system of sensors or that control a sensor, may be configured to process signals from the one or more sensors to identify a person. The processing may include evaluating features from the signals such as breathing rate, respiration depth, degree of movement and heart rate etc. The sensors may be radio frequency non-contact sensors with automated detection control to change detection control parameters based on the identification of living beings, such as to avoid sensor interference.

Manual resuscitators, ventilation control assemblies, and methods suitable for delivering a volume-controlled tidal volume of air to a patient's lungs. Such a resuscitator has a piston that pushes a selected volume of air out of a ventilation chamber of a cylinder in response to pressurized gases being introduced into an actuation chamber of the cylinder. A volume adjuster adjusts the maximum tidal volume of patient air that the piston pushes out of the ventilation chamber by adjusting the maximum length of the piston stroke in the cylinder. The volume adjuster may have a bypass mode that allows the manual resuscitator to operate without volume control. The manual adjuster may also be pressure regulated by one or more pressure regulation valves.

A device and method of generating an enriched gas within a nasal vestibule of a patient includes a housing, a chamber, a chamber inlet, a pump, a molecular sieve bed, a release outlet, and a breath duct. The chamber is configured to be received within the nasal vestibule. The pump is configured to direct an ambient air from an ambient environment into the chamber. The molecular sieve bed is positioned within the chamber and configured to collect a predetermined molecule from the ambient air thereby generating the enriched gas. The release outlet is configured to discharge the enriched gas from the chamber into the nasal vestibule. The breath duct longitudinally extends through the housing such that the breath duct is configured to fluidly communicate a fluid flow through the housing for nasal breathing by the patient while the chamber is positioned within the nasal vestibule.
