The present invention discloses a Lung condition monitoring device for performing ultrafast detection of humidity level in exhaled air while breathing out and therefrom detect condition of the human lungs in real time. The Lung 5 condition monitoring device comprises a mouthpiece for forcibly exhaling air there through, one or more humidity sensor to measure the variable electrical resistance based on level of adsorption of water molecules thereon of the humidity content of exhaled air and real time monitoring unit operatively connected to said humidity sensor and having correlating means for correlating 10 the change in humidity level and related variation in the electrical resistance due to exhalation to peak flow rate of the exhaled air for monitoring lung condition. The Lung condition monitoring device is also capable of wireless data transfer to any peripheral computing device such as mobile phone via wireless connectivity and show the test results on the mobile phone display with the help of a 15 proprietary application embodied in the phones operating system. The mobile interface increases the portability, data monitoring, and user friendliness of the device. Further, the mobile interface helps in storage and analysis of big time data for prognosis, diagnosis, and therapeutic purposes.

A device including a first flow channel, a second flow channel and a body part including an inner volume. A first space of the inner volume is adapted to be filled with liquid and a second space of the inner volume is arranged to receive steam. The device further includes means for conveying a gas flow from the steam space of the inner volume via the first flow channel to the outside of the device during inhalation and means for conveying the exhaled gas flow from the outside of the device via the second flow channel to the first space of the inner volume. The device further includes means for measuring a flow and a temperature of an airflow, and means for adjusting the flow of the airflow mechanically and/or automatically. The present disclosure further relates to a method and a system.

The present disclosure describes a sleep staging system. The system comprises: one or more sensors configured to generate output signals conveying information related to breathing parameters of subject during a respiratory therapy session; and one or more physical computer processors configured by computer readable instructions to: determine, based on the output signals, one or more breathing features of individual breaths of the subject; determine a distribution of the one or more breathing features over a plurality of time windows, at least one of the time windows having a length of at least 60 seconds; determine sleep states of the subject by mapping the distribution of the breathing features to one or more sleep states using a sleep stage classifier model, the sleep stage classifier model configured to determine the sleep states; and provide feedback indicating the sleep states during the respiratory sleep session.

The present invention provides a device for alternatively indicating at least a first fluid flow rate and a second fluid flow rate. The device, which may be a spirometer (e.g. a peak flow meter) comprises an aperture, a mouthpiece and a body defining a fluid flow path extending between the aperture and the mouthpiece. The body comprises a fluid flow rate indicator operable to alternatively generate at least a first sound signal and a second sound signal indicative of the first or second fluid flow rate in a first direction. The fluid flow rate indicator comprises a corrugated portion having a plurality of corrugations extending into the fluid flow path.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.

Described herein are passive nasal respiratory devices, in particular, passive nasal respiratory devices configured to achieve positive end-expiratory pressure (PEEP) in a subject wearing the device. PEEP devices may have a threshold pressure for opening during expiration. These devices may include a flap valve that opens on inhalation nested with a spring valve that opens when exhalation pressure exceeds a predetermined threshold. The device may be configured to be comfortably worn by a sleeping subject.

The present disclosure describes a sleep staging system. The sleep staging system comprising: one or more sensors configured to generate output signals conveying information related to one or more breathing parameters of subject; and one or more physical computer processors operatively connected with the one or more sensors, the one or more physical computer processors configured by computer readable instructions to: determine, based on the output signals, one or more breathing features of individual breaths of the subject; determine a distribution of the one or more breathing features over one or more time windows; detect presence of a breathing event based on the output signals; determine sleep states of the subject with a sleep stage classifier model based upon the distribution of the breathing features and the one or more breathing events; and provide feedback indicating the sleep states.

A portable inhalation device includes a medication storage component, a flow controller, an atomizer, a medication delivery component, and a pressure sensor. The medication storage component is configured to store medication. The flow controller is configured to cause a force to be applied to the medication stored by the medication storage component to transport the medication to the atomizer. The atomizer is configured to generate droplets from the medication. The medication delivery component includes a delivery channel extending from the atomizer to an outlet opening. The medication delivery component is configured to receive the medication in the delivery channel from the atomizer and dispense the medication via the opening. The pressure sensor is configured to detect a pressure corresponding to a flow rate of air in the delivery channel and output an indication of the detected pressure.

The chronic nature of asthma necessitates regular self-monitoring of respiratory function in susceptible individuals, however the available devices for performing the necessary measurements are either inaccurate or expensive and bulky. The present invention provides a small, cheap spirometer for efficient, accurate and convenient measurement of breathing characteristics.

The present invention relates to the field of medical devices, and, more particularly, to a portable system for testing one or more lung functions, and novel techniques for noninvasive determination of one or more pulmonary function characteristics.
