Device and Methods for Applying Therapeutic Protocols to Organs of the Cardiopulmonary System

Номер: US20120103337A1
Автор: Yuval Avni
Принадлежит: RESPINOVA Ltd

The invention is a device for the introduction of a fluid into a human's airway. The air so introduced has a carefully modulated envelope of pressure vs. time, this envelope generally consisting of sequences of pressurized air packets of controlled frequency and pressures. The device produces these packets by means of pressurized air occluded by a shutter action which “chops” and interrupts the fluid stream. The vibrations induced by the device within human organs have been shown to have beneficial effects on various bodily systems, such as increase in heart rate variability, increase in absorbed oxygen, decrease in absorbed CO2, and the like.

Intermittent dosing of nitric oxide gas

Номер: US20120199123A1
Автор: Alex Stenzler, Bevin B. McMullin, Chris Miller
Принадлежит: Pulmonox Technologies Corp, Sensormedics Corp

A method and corresponding device are described for combating microbes and infections by delivering intermittent high doses of nitric oxide to a mammal for a period of time and which cycles between high and low concentration of nitric oxide gas. The high concentration of nitric oxide is preferably delivered intermittently for brief periods of time that are interspersed with periods of time with either no nitric oxide delivery or lower concentrations of nitric oxide. The method is advantageous because at higher concentration, nitric oxide gas overwhelms the defense mechanism of pathogens that use the mammalian body to replenish their thiol defense system. A lower dose or concentration of nitric oxide gas delivered in between the bursts of high concentration nitric oxide maintains nitrosative stress pressure on the pathogens and also reduces the risk of toxicity of nitric oxide gas.

Microfluidic device and method of use

Номер: US20120260718A1
Автор: Douglas Ray Sparks, Nader Najafi, Richard Thayre Smith
Принадлежит: Integrated Sensing Systems Inc

A microfluidic device and sensing method that utilize a resonating tube configured to have sufficient sensitivity to be capable of sensing the volume of a gas present as bubbles in a liquid or the flow rate and/or density of a gas or gas mixture flowing through the tube. The tube has a freestanding tube portion supported above a surface of a substrate so as to be capable of vibrating in a plane normal to the surface of the substrate. As a gas-containing fluid flows through an internal passage of the tube, a drive signal vibrates the freestanding tube portion at a resonant frequency thereof. Coriolis-induced deflections of the freestanding tube portion are sensed relative to the substrate to produce an output corresponding to the sensed deflections, and the drive signal and/or the output are assessed to determine the volume, density and/or flow rate of the gas of the gas-containing fluid.

Various embodiments are described herein for a controller for controlling the operation of a breathing assistance device that provides breathing assistance to a user. The controller comprises a processor that generates a respiratory index value that is determined during a current monitoring time period to detect a respiratory failure, or predict the respiratory failure when at least one PSG signal is measured. The respiratory index value is compared to a threshold to determine if the control signal needs to be updated to reduce or eliminate respiratory failure that the user is currently experiencing or to prevent a predicted respiratory failure from occurring.

Oxygen sensor assembly for medical ventilator

Номер: US20220031992A1
Автор: Gregory J. Glenn, Jose J. Aguirre, Matthew Tyson Grant
Принадлежит: COVIDIEN LP

The present invention relates to oxygen sensors for medical ventilators. A medical ventilator includes a patient circuit delivering inspiratory airflow to a patient and returning expiratory airflow from the patient back to the ventilator. A manifold includes an air flow path into the patient circuit, and a port with an opening for an oxygen sensor. When mated to the port, the oxygen sensor samples the air in the air flow path and detects the amount of oxygen in the air. When the oxygen sensor is inserted into the port, a valve is biased open, to allow airflow through the opening into the oxygen sensor during ventilation. When the oxygen sensor is removed from the port, the valve biases into a closed position covering the opening, to prevent leaks. The ventilator can then continue to operate without the oxygen sensor in place.

A therapeutic gas is administered to a patient. A sample gas is drawn from the therapeutic gas supply, and passed through a water-permeable tubular membrane. Concurrently, a section of the water permeable tubular membrane is maintained as a ventilated water permeable tubular membrane, by exposing outer surfaces of the ventilated water permeable tubular membrane to an ambient air flow. The ambient air flow may in some examples be moved over the tubular membrane via forced air such as for example via a fan associated with a housing surrounding the tubular membrane.
