Abstract: A breathing assistance device with improved pressure characteristics provides a high level of CPAP per unit of supplementary respirable gas consumed while maintaining low CPAP fluctuations throughout the breath cycle utilizing a frustrum-shaped air channel that has no unblocked openings to accelerate air flow. In some embodiments, a manometer is provided for monitoring pressure and/or a pressure relief valve is provided as a safety measure against overpressure delivered to a patient. In some embodiments, the device is disposable for one-time or single patient use.

Abstract: A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

Abstract: An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient as a patient inhales. The aerosol delivery system includes a pump coupled to the aerosol generator that pumps the fluid to the aerosol generator, and a breath sensor that emits a signal as the patient breathes. A controller couples to the aerosol generator, the pump, and the breath sensor. In operation, the controller receives the signal from the breath sensor, controls a flow of fluid to the aerosol generator in response to the signal, and controls the aerosol generator to start aerosolizing the fluid before the patient inhales.

Abstract: A ventilator (1) with a control unit (49). The control unit (49) controls the inhalation valve (41) and the exhalation valve (43) in order to raise an inhalation pressure level from a first pressure level to a predefined second pressure level and to maintain the inhalation pressure level for a first predefined time period and the control unit (49) controls the inhalation valve (41) and the exhalation valve (43) to raise the second pressure level to a predefined third pressure level and to maintain the third pressure level for a second predefined time period. The control unit (49) takes into consideration predefined values (80) for controlling the pressure levels and for controlling the time periods.

Abstract: An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.

Abstract: A ventilator adaptor for switching between ventilator devices while maintaining respiratory support to a patient is described. The ventilator adaptor has a first movable element with a first inlet and a second inlet, and a second movable element movably attached to the first movable element and with an outlet. The outlet has an inner diameter of 14.5-15.5 mm, preferably 15 mm, and the first inlet and the second inlet have an outer diameter of 14.5-15.5 mm, preferably 15 mm. The outlet is in fluid communication with the first inlet in a first position or with the second inlet in a second position by moving the second movable element relative to the first movable element thereby aligning the outlet with the first inlet or the second inlet. The outlet may be attached to an endotracheal tube in order to form a ventilation assembly.

Abstract: A system and method by which a catheter tube may be automatically driven to a target location within the body of a subject, such as an enteral cavity or respiratory tract of the subject. The catheter tube may include an imaging device, a transceiver, a spectrometer, and a battery embedded in a tube wall at a distal end of the catheter tube. The imaging device may capture image data of structures proximal to the distal end of the catheter tube. An articulated stylet may be inserted in the catheter tube, which may be controlled by a robotic control engine according to navigation data generated by an artificial intelligence (AI) model based on the topographical image data. The spectrometer may sample and identify biomarkers proximal to the catheter tube. A remote computer may implement the robotic control engine and AI model and may wirelessly receive the image data from the transceiver.
