5 results about "Expired air" patented technology

A tracheal connector is connected to a respiratory gas generator and a tracheal tube. The tracheal connector includes a tracheal connector body connected to the tracheal tube, a connector tube connected to the tracheal connector body and the respiratory gas generator, and a restriction mechanism configured to narrow a respiratory gas flow path configured to allow the respiratory gas to flow therein. The tracheal connector body includes a tracheal port connected to the tracheal tube, an exhaust port facing the tracheal port and configured to discharge at least expired air of the subject, and a respiratory port connected to the connector tube. The restriction mechanism is provided on the respiratory gas flow path between the respiratory port and the tracheal port.

Provided is a diagnostic support program that is possible to display a movement of an area whose shape 5 changes for each respiratory element including all or part of expired air or inspired air. There are provided processing of acquiring a plurality of frame images from a database that stores images, processing of specifying of a cycle of a 10 respiratory element including all or part of expired air or inspired air based on pixels in a specific area in each of the frame images, processing of detecting a lung field based on the cycle of the specified respiratory element, processing of dividing the 15 detected lung field into a plurality of block areas and calculating a change in image in a block area in each of the frame images, processing of Fourier-transforming a change in image in each block area in each of the frame images, processing of extracting a spectrum in a fixed 20 band including a spectrum corresponding to the cycle of the respiratory element, out of a spectrum obtained after the Fourier-transforming, processing of performing inverse Fourier transform on the spectrum extracted from the fixed band, and processing of 25 displaying each of the images after performing the inverse Fourier transform, on a display. 20 24 26 70 70 30 N ov 2 02 4 3 0 N o v 2 0 2 4 5 2 0 2 4 2 6 7 0 7 0

The utility model discloses a suite device for oxygen uptake and atomization under autonomous respiration, which comprises a shell, one end of the shell is connected with a tracheal catheter, the convenient requirement of a patient can be met through plug-in connection and quick connection and disassembly, the shell is provided with a lacing, the lacing can be used for fixing the lacing around the neck, and the lacing can be used for fixing the tracheal catheter. The other end of the shell is communicated with an atomization pipeline, a partition plate is further arranged in the shell, smooth breathing can be guaranteed, meanwhile, the oxygen inhalation and atomization utilization rate is increased, in addition, an expired air collecting pipe can be arranged, and the oxygen inhalation atomization device is quite suitable for a patient with a trachea cannula or a tracheotomy cannula in place in the autonomous breathing state. And the device has a relatively high application prospect in the aspects of oxygen uptake, atomization treatment and gas monitoring.

A wearable capnography device implemented in a form of piercing jewelry that can be worn in a nose or a mouth. The device includes miniaturized sensors to measure pCO2 values continually, wherein the sensor is positioned such as when the device is worn, the sensor is exposed to expired air from the nose or the mouth respectively. The wearable capnography device can be wirelessly coupled to an ear-worn receiver, which upon receiving a signal from the wearable capnography device can generate an audio and vibratory alarm.

A device for measuring the inspiration and expiration muscle strength of a patient by measuring the pressure of the air inspired and / or of the air expired by the patient, said device comprising a first tubular component (2) for measuring said pressure and a second component (4) to which the first component (2) is removably constrained, adapted to read the measurements carried out by the first component (2) and highlight them through a display (6) to the patient, said first component (2) having two check valves (38, 40) adapted to alternatively allow the flow of the inspired air and the flow of the of the expired air. The first component (2) has a tubular-shaped body (9) and it comprises a switch element to allow the patient to alternatively inspire and expire the air from said valves (38, 40), in said body (9) there being provided for a member (50) for measuring said pressure values.
