摘要:
Methods and systems of using liquid nitrogen dioxide (N 2 O 4 ) with a ventilator can generate and deliver nitric oxide to a patient by means of a ventilator.
摘要:
Various systems and devices for generating nitric oxide are disclosed herein. According to one embodiment, the device includes a body having an inlet, an outlet, and a porous solid matrix positioned with the body. The porous solid matrix is coated with an aqueous solution of an antioxidant, wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the solid matrix to convert nitrogen dioxide in the gas flow into nitric oxide. The porous solid matrix allows the device to be used in any orientation. Additionally, the porous solid matrix provides a rigid structure suitable to withstand vibrations and abuse without compromising device functionality.
摘要:
A system for delivering a therapeutic amount of nitric oxide can include a reservoir including a restrictor with a length of at least 0.5 inch and at most 2 inches covered by a metal sheath, a gas supply, and a delivery conduit. A delivery conduit can include at least one cartridge and a patient interface. The at least one cartridge can include a surface-active material and a reducing agent.
摘要:
A system for the delivery of nitric oxide can include a first platform including a first source of nitric oxide, a second platform including a second source of a nitric oxide, a delivery line coupled to the first platform and the second platform, and a controller configured to operate the first platform and the second platform simultaneously. A method of delivering nitric oxide can include communicating a first gas including nitric oxide through a first platform to a delivery line, communicating a second gas including nitric oxide through a second platform to the delivery line, and delivering the first gas and the second gas to a mammal via a delivery line.
摘要:
A method of delivering nitric oxide can include mixing a first gas including oxygen and a second gas including a nitric oxide-releasing agent within a receptacle to form a gas mixture, where the receptacle includes an inlet, an outlet and a reducing agent, contacting the nitric oxide-releasing agent in the gas mixture with the reducing agent to generate nitric oxide, and delivering the gas mixture including nitric oxide from the receptacle to a mammal.
摘要:
A nitric oxide delivery system, which includes a gas bottle having nitrogen dioxide in air, converts nitrogen dioxide to nitric oxide and employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid. A nitric oxide delivery system may be used to generate therapeutic gas including nitric oxide for use in delivering the therapeutic gas to a mammal.
摘要:
In one aspect, a system for delivering nitric oxide to a patient can include a first gas source including nitrogen dioxide mixed in air or oxygen, a second gas source supplying compressed air, a ventilator coupled to the first and second gas sources, where the ventilator can be resistant to nitrogen dioxide, and where the ventilator provides a gas flow having a proper amount of nitrogen dioxide, one or more conversion devices operably coupled to the ventilator, where the conversion devices covert nitrogen dioxide into nitric oxide, and a patient interface operably coupled to the conversion devices, where the patient interface delivers nitric oxide to the patient.
