Nasal breathing apparatuses for delivering gases, monitoring end-tidal CO2, and providing CPAP and NIV through a patient's nose are provided, including a central tubular chamber, a pair of nasal sealing members, one or a pair of breathing tube(s), an inner central tube, one or a pair of delivery tube(s), and a pair of side straps coupled with a head strap. Inner central tube and delivery tube(s) are positioned inside central tubular chamber and breathing tube(s), respectively. Alternatively, central tubular chamber and breathing tube(s) have a double lumen configuration. The nasal breathing apparatuses are compact and lightweight and have reduced noise during use.

An inhaler comprises (a) a first passage having a first open end and a second open end; (b) a pressure source configured for generating an airflow; said pressure source connected to said first open end of said first passage; (c) a rotating shutter configured for blocking and releasing said airflow; (d) a mouthpiece being in fluid communication with second open end of said first passage; said mouthpiece configured for delivering a modulated airflow to a patient's airway. The inhaler further comprises a second passage having first open end and a second open end; said first open end of said second passage is in fluid communication with said mouthpiece; said second open end of said second passage is vented to ambient air; said first and second passages are arranged such that said rotating shutter blocks and releases said first and second passages in an alternate manner.

A system for artificial ventilation including a convertible ventilator circuit having at least one inspiratory filter and at least one expiratory filter. The convertible ventilator circuit compatible with and configured to be used with either a manual ventilator or a mechanical ventilator. The convertible ventilator circuit configured to convert between manual ventilation use and mechanical ventilation use. The system including a patient manifold having one or more sensor ports and a data acquisition unit having one or more sensors configured to interface with the one or more sensor ports of the patient manifold. The data acquisition unit configured to receive electronic data associated with transmission of respiratory gases through the convertible ventilator circuit.

An oxygen mask that incorporates chemical carbon dioxide (EtCO2) detectors to allow for the monitoring of patient respiration/ventilation without the use of clinical signs or electronic computer technology by providing a visual indication (through color change of the EtCO2 detectors) of the presence or absence of carbon dioxide.

A respiratory device provides respiratory support to a patient. The respiratory device includes an expandable bag and a rigid valve housing. The expandable bag has an air inlet valve as well as a first and second sides that are bounded, respectively, by first and second rigid side panels. Each of the first and second rigid side panels includes a biasing member projection. The rigid valve housing is in fluid communication with the expandable bag. The rigid valve housing includes an adjustable tidal volume control device that interfaces with the biasing member projection of each of the first and second rigid side panels to set one of a plurality of predetermined tidal volumes for the expandable bag in an uncompressed or compressed configuration. The rigid valve housing additionally includes a patient breathing interface connection member.

A mask is provided with a mask body part configured to cover a face of a subject, and a cushion member fixed to the mask body part and contacts the face of the subject. The mask body part has an inner side face at least a portion of which faces the face of the subject, an outer side face positioned on an opposite side to the inner side face, and a plurality of protrusion portions provided on the outer side face. The cushion member has a plurality of engagement portions each of which is engaged with a corresponding one of the plurality of protrusion portions.

A system and method are for authentication and a system and method are for authentication based personal service

An aerosol-generating system is provided, including: a health monitoring device including a sensor to collect health data from a user, a controller to receive the health data and determine a health parameter based on the data, and a health monitoring device power supply to supply electrical power to the controller and the sensor, the device not being an aerosol generator; an aerosol-generating device including a cavity to receive a plug of tobacco, an aerosol-generator to generate aerosol from the plug, and an aerosol-generating device power supply configured to supply electrical power to the aerosol-generator; and a charger including a cavity to receive the health monitoring and aerosol generating devices, and a charger power supply to transfer electrical power to the health monitoring device power supply, and from the charging unit power supply to the aerosol-generating device power supply, the cavity being a single cavity.

This invention relates to a breath indicator for providing an indication of an inhalation and/or exhalation state of a user. Said breath indicator comprising a body comprising a gas sampling portion configured for receipt of a user's inhalation and/or exhalation gases, and an indicator portion. Said gas sampling portion in fluid communication with said indicator portion. Said indicator portion comprising at least a first region and at least a second region, the first region comprising a gas parameter detecting material capable of changing between an initial visual state and a subsequent visual state indicative of detection of a gas parameter of inhalation and/or exhalation gases of said user; and wherein said initial visual state and/or said subsequent visual state of the first region visually contrasts with a visual state of at least said second region.
