A system for respiration-controlled application of aerosol in powder form during artificial respiration or assisted respiration of a patient including an interface contacting the patient's respiratory tract, a unit for generating a respiratory gas flow, at least one inspiration line through gas flow is conducted to the interface, an aerosol generator, at least one aerosol line through which the generated aerosol is conducted from the aerosol generator to the interface, and a respiration sensor that detects the patient's respiration signal. A valve in the at least one aerosol line is controlled based on the detected respiratory signal.

The gas flow has a first pressure that is higher than or equal to ambient pressure and the aerosol has a second pressure that is higher than or equal to the first pressure.

The invention relates to a liquid store for an inhaler (10), in particular for an electronic cigarette product, having an outlet end (53) which can be fluidically connected to a heating element (60) in order to evaporate liquid (50) supplied to the heating element (60) from the liquid store (18). The liquid store (18) has at least one air inlet end (52) and at least one channel (51). The channel (51) extends from the air inlet end (52) to the outlet end (53) through the liquid store (18), wherein the channel (51) is designed to transfer the liquid (50) stored in the liquid store (18) to the outlet end (53) through the channel (51) via capillary forces.

A mechanical ventilation device comprising at least one electronic controller configured to receive imaging data and transpulmonary pressure data associated with a lung of a patient; perform deformable image registration of the inhalation image and the exhalation image to produce a relative compliance or elasticity map of the lungs; convert the relative compliance or elasticity map of the lungs to a quantitative compliance or elasticity map of the lungs based on the inhale transpulmonary pressure and the exhale transpulmonary pressure; and display the information relating to or derived from the quantitative compliance or elasticity map on a display device.

A pump arrangement for powering a pump in providing a controlled volume of water to a drip nozzle in a drip-feed humidifier. The pump arrangement includes: a pump having a solenoid; a processing unit; and a power supply electrically connected to the solenoid via a switch which is controlled by the processing unit. The power supply is structured to supply power to the solenoid via the switch. The processing unit is programmed to modulate the power provided to the solenoid via the switch such that the power is supplied to the solenoid according to a mirror image power profile for each actuation of the solenoid for retracting the armature. The mirror image power profile includes: an initial portion which decreases at a third overall rate, an intermediate portion which decreases at a second overall rate different than the third overall rate, and a final portion which increases at a first overall rate.

Systems and methods are provided for delivering one or more drugs. In some embodiments, a drug delivery system includes a housing having a distal end with an inlet through which an inspiratory flow of air passes into the housing, a proximal end having a patient interface attached thereto, the patient interface being configured to interface with a user, and an inspiratory flow pathway extending from the distal end to the proximal end of the housing. A nitric oxide (NO) source is positioned within the housing and is configured to deliver NO-containing gas to the patient interface. A secondary drug source is positioned within the housing and is configured to deliver a secondary drug to the patient interface. A controller is configured to control an amount of NO-containing gas and an amount of the secondary drug delivered using a control scheme.

A system and process for an oxygen flow control system for supplemental oxygen is provided, including a system with an optical flow sensor and 3-way solenoid that operate to detect inhalation and deliver a microburst of oxygen that is electronically controlled based on one or more parameters.

Disclosed herein is a system and method for controlling oxygen supply equipments. The system is equipped with pressure sensors coupled to the oxygen supply equipments. Depending on the oxygen supply selected by a user for the patient, the pressure sensor monitors the current pressure of the preset oxygen supply during an inhalation phase corresponding to the patient. If the current pressure is less than a minima value or if a pressure drop rate is higher than or equal to a threshold rate or both, the system generates an alarm notifying the user to check the preset oxygen supply and in the meanwhile switches the preset oxygen supply from one oxygen supply equipment to another oxygen supply equipment or vice-versa.

A power supply unit of an aerosol generating device includes: an accommodating portion with a bottom and cylindrical shape, which is configured to accommodate a columnar cartridge that stores an aerosol source in a state in which the cartridge is rotatable 360 degrees in a circumferential direction of the cartridge. A rotation suppressing portion configured to generate a frictional force between the cartridge and the rotation preventing portion so as to suppress rotation of the cartridge in the circumferential direction is provided on a bottom portion of the accommodating portion.

A ventilator (100), for mechanical ventilation of a patient (102), includes a sensor unit that measures a course profile (114) of gas flow-dependent measured values (115) in a ventilation circuit (105) of the ventilator and outputs a corresponding sensor signal (116). A plurality of ventilation parameters (122) of a provided ventilation mode, stored in a memory unit (120), indicate an inspiration time (124) of the ventilation currently provided and a subsequent expiration time (126) for a corresponding breathing cycle. A processing unit (130) is configured to receive the sensor signal, to determine at least one current end-expiratory gas flow (132) based on the course profile and to adjust a ratio (136), between the inspiration time and the expiration time, for the current ventilation mode depending on a comparison between the determined current end expiratory gas flow and a lower threshold value (134) and/or an upper threshold value (135).

A personal vaporizer device, especially an electronic smoking article, comprises a cartridge which includes a reservoir for storing a liquid to be vaporized; and an elongate body portion to which the cartridge is connected. The elongate body portion comprises a cover member which is movable in a longitudinal direction of the body portion between a first position and a second position, wherein the cartridge is substantially covered or obscured by the cover member in the first position. In the second position, the cover member is retracted.
