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.

Piezoelectric blower piloted valve

Номер: US20130167843A1

Автор: Gardner Kimm, Peter Doyle

Принадлежит: Nellcor Puritan Bennett LLC

This disclosure describes systems and methods for piloting a pneumatic valve using one or more piezoelectric blowers. According to embodiments, the one or more piezoelectric blowers may be coupled to the pneumatic valve to form a small, light-weight pneumatic valve that may be placed proximal to a ventilated patient, e.g., at the patient wye or the patient interface. Due to the close coupling of the one or more piezoelectric blowers, the pneumatic valve has a substantially shorter response time than traditional pneumatically piloted valves. Moreover, when piezoelectric blowers are coupled to the pneumatic valve in parallel, response time may be further decreased. Additionally or alternatively, when piezoelectric blowers are coupled to the pneumatic valve in series, pilot pressure may be increased as a function of the number of piezoelectric blowers in the series.

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.

This disclosure describes systems and methods for monitoring and evaluating ventilatory parameters, analyzing those parameters and providing useful notifications and recommendations to clinicians. That is, modern ventilators monitor, evaluate, and graphically represent multiple ventilatory parameters. However, many clinicians may not easily recognize data patterns and correlations indicative of certain patient conditions, changes in patient condition, and/or effectiveness of ventilatory treatment. Further, clinicians may not readily determine appropriate ventilatory adjustments that may address certain patient conditions and/or the effectiveness of ventilatory treatment. Specifically, clinicians may not readily detect or recognize the presence of double triggering during ventilation. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect double triggering and may issue notifications and recommendations suitable for a patient to the clinician when double triggering is implicated. The suitable notifications and recommendations may further be provided in a hierarchical format.

A portable nasal ventilation assembly and system having a nasal piece with fluid delivery ports which engage and occlude the nares of a patient and provides sustained oxygen saturations greater than 90% with lung afflictions requiring high-flows such as Pulmonary Fibrosis. The assembly is noninvasive and does not require the use of positive pressure machines that can only be used within the confines of a hospital intensive care unit. It can be used on patients with different respiratory problems. Patients on the system can be home while awaiting further hospital treatment, such as (for example) a lung transplant, for a fraction of the cost of a hospital stay. Although the system does not replace ventilator devices, it is effective for spontaneously breathing patients that require ventilators to maintain an adequate life sustaining oxygen level. The device allows for portability and can reduce hospital stay and cost dramatically.

Автор: Holley Liam, Klasek Paul Jan, Malouf Gordon Joseph

Принадлежит: ResMed Pty Ltd

Components for a respiratory treatment apparatus that is capable of providing a humidified respiratory treatment permit a reduction in condensation in a patient interface and/or its gas delivery tubing. In some embodiments, a rainout valve that may be an integrated component of a humidifier output aperture, or coupled thereto, may reduce condensation with a vapor barrier operable to selectively block and permit humidified gas transfer from the humidifier. For example, the barrier may be operable to open in response to a flow of pressurized breathable gas that may be generated by a flow generator of the respiratory treatment apparatus. In the absence of such a generation of pressurized flow, the barrier may prevent a transfer of the humidified gas such as into a conduit for a patient interface by retracting to a closed position. Example vapor barriers may include a resilient membrane, cover, bellows, flap, shutter or other suitable valve. 1.
