    摘要： A drug delivery system including a housing having a distal end with an inlet through which an inspiratory flow of air passes into the housing, a proximal end having a patient interface attached, the patient interface being configured to interface with a user, and an inspiratory flow pathway extending from the distal end to the proximal end of the housing. A nitric oxide (NO) source is positioned within the housing and is configured to deliver NO-containing gas to the patient interface. A secondary drug source is positioned within the housing and is configured to deliver a secondary drug to the patient interface. A controller is configured to control an amount of NO-containing gas and an amount of the secondary drug delivered using a control scheme.

    摘要： System and methods are provided for generating nitric oxide (NO). In some embodiments, systems comprise a microwave generator configured to produce microwave energy of varying pulse duration, pulse frequency, and power level and a microwave cavity configured to utilize microwave energy to generate a plasma ball within a flow of reactant gas containing nitrogen and oxygen flowing through the microwave cavity to produce a product gas containing NO. At least one stub can be positioned in the microwave cavity and is configured to focus the microwave energy at a location at which the plasma ball is formed. A controller in electrical communication with the microwave generator can be configured to control the microwave generator to initiate and maintain the plasma ball so the plasma ball is suspended in the flow of reactant gas and does not contact a surface of the at least one stub and the microwave cavity.

    摘要： Ventilator system with multiple inspiratory lumens is provided. The inspiratory lumens are configured so that separate inspiratory lumens provide inspiratory gas mixtures to separate portions of a patient's airways, for instance to separate lungs and/or bronchi. The ventilator system can include one or more expiratory lumens to evacuate expiratory gases from airways. The use of separate inspiratory lumen(s), with expiratory lumen(s), allows for functional separation of structural portions of the lungs, and maintenance of continuous or almost continuous flow through at least part of respiratory cycle via inspiratory and expiratory lumens. This can further reduce dead space and clear suspended therein diseases causative agents with improvement in outcomes, reduce risk of cross-contamination or cross-infection between different parts of airways, for example such as cross-infection from one lung lobe to another lobe or. The ventilator system allows for independent titration of PEEP, pCO2 and pO2 with no need for permissive hypercapnia.

    摘要： Aspects of the disclosure describe a design that isolates concentrated oxygen from electrical and/or flammable components of a ventilator. In an example, ventilator components containing or otherwise interacting with concentrated oxygen are isolated from the electrical equipment and/or drained to an exterior of the housing of the ventilator, in case of a leak. For example, an isolating structure encases the concentrated oxygen-carrying components to prevent concentrated oxygen from inadvertently leaking into the inside of the housing of the ventilator. The isolating structure may be a sleeve. An isolation gas inside the isolating structure may be fluidly coupled with ambient air outside the housing of the ventilator to allow the escape of isolation gas outside of the ventilator housing.

    摘要： 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. A method of using an apparatus suitable for a ventilator is also disclosed.
