An inhaler configured and adapted for inhaling an inhalation medium, enriched with active ingredients and/or flavouring substances, includes a cartridge carrier, a storage tank which contains the inhalation medium, a mouthpiece which is associated with the cartridge carrier, and an actuating mechanism for releasing the inhalation medium out of the storage tank in the direction of the mouthpiece. The inhaler has at least one sensor associated with the mouthpiece. The sensor is configured and adapted to detect characteristics of lips of the person using the inhaler and to provide a data signal formed from the characteristics. The sensor is connected to an electronic control unit associated with the inhaler, to which the actuating mechanism is also connected, in such a manner that the inhalation medium is released on the basis of the data signal. A corresponding arrangement and a corresponding method are disclosed.

Systems and methods are provided related to signal conditioning and analysis methods for detecting respiratory events of a human or an animal. Respiratory events detected can either serve as input to a drug delivery system or be a stand-alone breath detection device. Various methods for sensing respiratory events, processing respiratory signals, and analyzing respiratory signals are provided with the goal of enabling accurate and reliable detection of specific types of events in a respiratory cycle.

An oxygen concentration system may comprise a pressure sensor, a movement sensor, and a controller configured to use one or more pressure signals obtained from the pressure sensor and a movement signal obtained from the movement sensor to determine when to release a bolus of oxygen enriched air. In some implementations, the controller may adjust a trigger threshold based on an initial pressure signal obtained from the pressure sensor and the movement signal obtained from the movement sensor. In some implementations, the controller may adjust a pressure signal obtained from the pressure sensor based on the movement signal obtained from the movement sensor. In some implementations, the controller may detect a potential onset of inhalation from a pressure signal obtained from the pressure sensor and determine whether to verify the potential onset of inhalation based on the movement signal obtained from the movement sensor.

Systems and methods for managing the power consumption of an oxygen concentrator are disclosed. An oxygen concentration system may comprise a compression system, a canister system, one or more processors, and at least one of a pressure sensor or a movement sensor. The one or more processors may be configured to transition the oxygen concentration system to at least one of a prescribed mode of operation or a standby mode of operation. The timing of the transition may be based on at least one of a number of breaths detected from the pressure signals generated by the pressure sensor or an estimated energy content of the movement signal generated by the movement sensor. A predetermined volume or concentration of oxygen enriched air may be supplied to a user during the prescribed mode of operation. A reduced power may be provided to the compression system during the standby mode of operation.

Introduced here is a self-contained face mask system with an automated liquid-droplet dispensing mechanism (ADM) for humidification. The enclosure of the self-contained mask system can be comprised of one or more layers of breathable fabric adapted to flexibly conform to the face of a user when worn to form a cavity that is adjacent the nostrils and mouth. The ADM of the face mask system can be comprised of a reservoir in which liquid is stored, a respiratory cycle detector, a timer and controller, and a droplet dispenser that controllably dispenses droplets of the liquid from the reservoir into the cavity for inhalation by the user. The ADM can be contained entirely within the face mask enclosure or supported on the surface of the face mask enclosure such that the self-contained mask system, when worn by a user, can be supported entirely by the head and neck of the user.

The present disclosure provides for a control system for a flow therapy apparatus. The control system can control delivery of a fraction of delivered oxygen (FdO2) to a patient. The control system can maintain the FdO2 at a target level during a therapy session. The control system can automatically control an oxygen inlet valve in order to control the flow of oxygen to the patient.

The present invention provides an inhalation device with which it is possible to improve usability and promote users' safety and satisfaction with the inhalation device. An inhalation device according to the present invention is provided with a first member and a second member which is configured to be capable of being attached to and detached from the first member. This inhalation device includes: an active functional part which is provided to the first member; a passive functional part which is provided to the second member and which is capable of changing the state thereof according to the working of the active functional part; a sensor part which is provided to the first member and which detects a changed state of the passive functional part; and a control part which, on the basis of the detected state, determines whether the second member has been attached to the first member.

A gas therapy system (1) has a flow line (3, 2), a coupler (6) to a gas source, and an aerosol generator (4) for aerosol delivery, and a patient interface such as a nasal interface (2). A controller (10) is configured to modulate gas flow and aerosol delivery in real time. The controller changes gas flow rate and dynamically reduces aerosol delivery during upper gas flow rates such as 60 LPM, and activates aerosol delivery during lower gas flow rates of for example 10 LPM. The control may also include sensors to detect breathing, so that there is a bias towards increased aerosol delivery during inhalation in addition to during lower level gas flow.

Methods and apparatus for treating a respiratory disorder, in one aspect, include an apparatus that delivers backup breaths at a sustained timed backup rate that is a function of the patient's spontaneous respiratory rate. Other aspects include apparatus that delivers backup breaths at a rate that gradually increases from a spontaneous backup rate to a sustained timed backup rate or, alternatively, apparatus that oscillates a treatment pressure in antiphase with the patient's spontaneous respiratory efforts when a measure indicative of ventilation is greater than a threshold. Other aspects include apparatus configured to treat Cheyne-Stokes respiration by computing the treatment pressure so as to bring a measure indicative of ventilation of the patient towards a target ventilation that is dependent on the measure indicative of ventilation or, alternatively, by periodically elevating the treatment pressure to a high level for a short time, the high level being high enough and the short time being long enough to induce a central apnea in a patient. Depending on functionality, the foregoing apparatus may comprise an adaptive servo-ventilator or CPAP therapy device.

A process and apparatus monitor a ventilator (100). The ventilator (100) performs supportive artificial ventilation including a sequence of ventilation strokes, with the objective that each inspiration effort of the patient (Pt) triggers a ventilation stroke and the start and the end of the ventilation stroke coincide with the start and the end of the inspiration effort, respectively. A monitoring unit (11) detects deviations between the patient's own inspiratory efforts and the artificial ventilation and determines a respective measure for the respective frequency and/or duration for different possible asynchrony types.
