摘要： A ventilator that delivers air at different pressures to a patient during inspiratory and expiratory cycles of breathing and that cycles from inspiratory to expiratory operation when the patient's respiratory flow passes a threshold level. The threshold generally increases from the beginning of inspiration to the end of inspiration. The increase can be linear over all or only a portion of the inspiratory cycle, and the threshold can be adjusted so that cycling is prevented during the initial portion of an inspiratory cycle. The minimum and maximum levels may both be functions of peak flow and the threshold may increase as a function of elapsed inspiratory time. The rate at which the threshold increases from a minimum level to a maximum level may be adjustable for individual patient needs and may be determined from previous breaths.

摘要： A device that reduces human energy loss in the breathing process, without requiring external energy such as electricity. The device transfers motion, elastic or heat energy by conveying air volume and pressure between the exhaling and inhaling phases in the breathing process in order to adjust the air pressure or temperature in these phases so as to improve air perfusion or the body's thermal homeostatic conditions as required, in addition to reducing the air resistance in masks or respirators used for protection against contaminants. The invention pertains to the field of healthcare. The invention comprises inhalation and exhalation chambers that are associated with air pumps, besides having elastic energy accumulation walls to minimize air flow resistance.

摘要： An aerosol provision system comprises a heating element for generating an aerosol from a source liquid and control circuitry for controlling a supply of electrical power from a power supply to the heating element. The control circuitry is configured to measure an indication of a derivative of an electrical characteristic of the heating element with respect to time. Based on the measured time derivative, the control circuitry is configured to determine whether or not a fault condition has arisen for the electronic aerosol provision system. The overall change in the electrical characteristic for the heating element caused by the localized heating may be small and so difficult to reliably identify, but the rate at which the change occurs can be expected to be relatively high, such that the time derivative of the local characteristic is a more reliable indicator of occurrence of the fault condition.

摘要： A breathable gas inlet control device permits flow regulation at the inlet of a flow generator for a respiratory treatment apparatus such as a ventilator or continuous positive airway pressure device. The device may implement a variable inlet aperture size based on flow conditions. In one embodiment, an inlet flow seal opens or closes the inlet to a blower in accordance with changes in pressure within a seal activation chamber near the seal. The seal may be formed by a flexible membrane. A controller selectively changes the pressure of the seal activation chamber by controlling a set of one or more flow control valves to selectively stop forward flow, prevent back flow or lock open the seal to permit either back flow or forward flow. The controller may set the flow control valves as a function of detected respiratory conditions based on data from pressure and/or flow sensors.

摘要： In a respiratory apparatus for treatment of sleep apnea and other disorders associated with an obstruction of a patient's airway and which uses an airflow signal, an obstruction index is generated which detects the flattening of the inspiratory portion of the airflow. The flattening index serves as an obstruction index used to differentiate normal and obstructed breathing. The obstruction index is based upon comparison of values of airflow in different sectors of the inspiratory peak of the wave function and is particularly suitable for distinguishing M shaped or square shaped respiratory patters patterns indicative of partially obstructed airways.

摘要： A system for providing ventilation support to a patient may include a ventilator, a control unit, a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface, and a nasal interface. The nasal interface may include at least one jet nozzle at the distal end of the gas delivery circuit; and at least one spontaneous respiration sensor for detecting respiration in communication with the control unit. The system may be open to ambient. The control unit may receive signals from the at least one spontaneous respiration sensor and determine gas delivery requirements. The ventilator may deliver gas at a velocity to entrain ambient air and increase lung volume or lung pressure above spontaneously breathing levels to assist in work of breathing, and deliver ventilation gas in a cyclical delivery pattern synchronized with a spontaneous breathing pattern.
