A mount provides a structure that facilitates coupling of a nebuliser downstream of a humidifier chamber and upstream of a conduit that delivers conditioned breathing gases to a patient or user. The mount can couple together a chamber, a nebulizer and a conduit.

The subject matter of the application is a device for adjustment and/or regulation of the CO.sub.2, carbon dioxide content of the inhaled air. Device based on the invention where a CO.sub.2 vessel 30 is connected to the CO.sub.2 input aperture 22, a measuring tool 15 determining the CO.sub.2 content of the exhaled air is connected to the exhaled air pipe 11, the output aperture of the measuring tool 15 is connected to the input aperture of a control unit 50, and the output aperture of the control unit 50 is connected to the valve 28 adjusting the blending rate of blending vessel 20 and so adjusting the CO.sub.2 content of the inhaled air.

Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, incorrect connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if reverse flow conditions or other error conditions exist. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The methods can be implemented at the humidifier side, at the gases source side, or both.

A diagnostic tool can include a face mask, a casing, a plurality of sensors, and processing circuitry. The face mask can include an air-intake port, a first check valve integrated into the air-intake port, an air-exhaust port, and a second check valve integrated into the air-exhaust port. The casing can be coupled to the face mask having an air-intake chamber coupled to the air-intake port and an air-exhaust chamber coupled to the air-exhaust port. The processing circuitry can be communicatively coupled to the plurality of sensors. The processing circuitry can include computing logic for handling information detected by the plurality of sensors.

The present invention relates to a computer-vision based autonomous steerable catheter device and methods of using the same for targeted delivery of a liquid microvolume into the interior of a lung.

The present invention relates to a sleep-inducing system using carbon dioxide. The sleep-inducing system includes a mixed gas generation unit which generates a mixed gas of which a carbon dioxide concentration is within a preset range by mixing provided carbon dioxide and air, an emission unit which sprays the mixed gas from a position spaced apart from a user's face, a concentration sensing sensor which measures the carbon dioxide concentration of the sprayed mixed gas, and a control unit which controls the carbon dioxide concentration of the mixed gas generated by the mixed gas generation unit to be within the preset range on the basis of the measured carbon dioxide concentration.

A ventilation monitoring system for assisting in proper placement of an endotracheal tube in a subject includes: a capnography sensor configured to be placed in fluid communication with the endotracheal tube and to provide information representative of the subject's breath; and a processor in communication with the capnography sensor. The processor is configured to provide an indication of proper endotracheal tube placement when (1) a first indication of the subject's breath and a positive result of a first auscultation are identified within a first predetermined time period, and (2) a second indication of the subject's breath and a positive result of a second auscultation are identified within a second predetermined time period. The first auscultation includes auscultation of a subject's left lung, right lung, left axillary region, right axillary region, or abdomen. The second auscultation includes auscultation of another region of the subject different from the first auscultation.

An apparatus such as a fluid mixer, suitable for use with a respirator, including a venturi nozzle for flow of a pressure-controlled fluid; an ambient fluid aperture in fluid communication with the venturi nozzle; a fluid port; a pressure force multiplier in fluid communication with the fluid port; and a valve moveable relative to the venturi nozzle between a start flow position and a stop flow position; where the pressure force multiplier is configured such that fluid forced into the fluid port actuates the valve relative to the venturi nozzle; and where the pressure force multiplier is configured such that fluid withdrawn from the fluid port actuates the valve relative to the venturi nozzle, further comprising an active filter that comprises an energy harvesting system and at least one filter medium, wherein the energy harvesting system generates electricity to induce a static charge in the at least one filter medium.

Systems and methods are provided for portable and compact nitric oxide (NO) generation that can be embedded into other therapeutic devices or used alone. In some embodiments, an ambulatory NO generation system can be comprised of a controller and disposable cartridge. The cartridge can contain filters and scavengers for preparing the gas used for NO generation and for scrubbing output gases prior to patient inhalation. The system can utilize an oxygen concentrator to increase nitric oxide production and compliment oxygen generator activity as an independent device. The system can also include a high voltage electrode assembly that is easily assembled and installed. Various nitric oxide delivery methods are provided, including the use of a nasal cannula.

A nasal ventilation mask having one or more attachment ports located adjacent to and overlying an upper lip of a patient when worn.
