Abstract: A breathing apparatus has an expiratory flow sensor unit, an expiratory pressure sensor unit, an expiratory pressure regulator, and an expiratory control unit operatively connected to the expiratory pressure sensor unit for a feedback control of an expiratory pressure during an expiratory phase of a breathing cycle. The expiratory control unit is adapted to provide a real time target pressure value during the expiratory phase to the expiratory pressure regulator for adjusting a desired positive end expiratory pressure (PEEP) level (PEEPset) based on an inspiratory tidal volume of an inspiratory phase of the same breathing cycle and a currently accumulated expiratory tidal volume measured by the expiratory flow sensor unit. In this manner advantageous regulation of PEEP with minimized work of breathing is obtained.

Abstract: An patient interface that reliably maintains a seal between it and the patient. The patient interface advantageously includes a deformation portion at its point of connection with an air supply, with the deformation portion being relatively more deformable than the other portions of the patient interface in order to resist torque applied by the air supply from disturbing the seal between the patient interface and the patient. While the air supply is pivotably connected with the patient interface and is pivotable about a pivot axis, a torque applied about an axis other than the pivot axis results in deformation of the deformation portion and thus advantageously avoids breaking the seal between the patient interface and the patient.

Abstract: This invention relates to a measuring head which comprises an intake, an outlet, a mouthpiece and an electrically controlled proportional valve. The intake may be connected to a pressurized gas reservoir. The outlet releases exhaled gas and excess gas into the ambient. A mouthpiece provides gas to a subject and accepts exhaled gas from the subject. The electrically controlled, proportional valve is pneumatically connected between said intake and said mouthpiece for controlling the gas flow from said intake to said mouthpiece and said outlet. The invention further relates to a method for controlling a gas flow from the intake to the outlet.

Abstract: A modularized respiratory treatment apparatus provides various respiratory pressure treatments. The apparatus may be formed by discrete connectable modules such as a flow generator module, alarm module and/or humidifier module. Each module may include its own external casing or housing to independently retain or enclose the respective components that serve the function of the module. Different modules may be adapted with different components and functionalities and may be readily coupled using standardized gas and electrical connection configurations that have flow and communication paths that extend through the modules. When coupled, operation of the respiratory treatment apparatus may be controlled by detection of different modules, such as the alarm module that generates visual and/or audible alarms based on detected conditions, so as to selectively enable or disable different respiratory treatments.

Abstract: A walking assist device is capable of operating at an appropriate cycle in view of the motion cycle of a human being to be assisted while at the same time reducing the number of control parameters to be adjusted or set. A second phase oscillator, based on which the phase of the periodic operation of each actuator is controlled, is calculated on the basis of the difference between a first phase oscillator, which indicates a phase of the periodic motion of each thigh relative to the upper body of a human being, and the second phase oscillator, and an intrinsic angular velocity. A current intrinsic angular velocity is set by correcting a previous intrinsic angular velocity by an amount based on a previous difference between the first phase oscillator and the second phase oscillator such that the previous difference approaches a desired difference.

A dose chamber having an opening may hold a dose, e.g., for inhalation by a user. A disc element may be arranged to move between a closed position in which the disc element closes the opening of the dose chamber, and an open position in which the disc opens the dose chamber to permit introduction of the dose into the air path of the device. Movement of the disc element from the closed position to the open position may be in a direction away from the dose chamber (e.g., a puller may engage the disc element and pull the element away from the chamber) and may leave a substantial portion of the dose in the dose chamber.
