Device and method for treatment of wounds with nitric oxide
InactiveUS7122018B2Promote wound healingReduce the burden onBiocideOther blood circulation devicesHigh concentrationNitric oxide gas
Topical exposure of nitric oxide gas to wounds such as chronic non-healing wounds may be beneficial in promoting healing and preparing the wound bed for further treatment and recovery. Nitric oxide gas may be used to reduce the microbial infection, manage exudates secretion by reducing inflammation, upregulate expression of endogenous collagenase to locally debride the wound, and regulate the formation of collagen. High concentration of nitric oxide ranging from 160–400 ppm may be used without inducing toxicity in the healthy cells around a wound site. Exposure to the high concentration for a first treatment period reduces the microbial burden and inflammation, and increases collagenase expression to debride necrotic tissue at the wound site. After a first treatment period, a second treatment period at a lower concentration of nitric oxide, preferably ranging from 5–20 ppm may be used to restore the balance of nitric oxide and induce collagen expression aiding in the wound closure.

An exhaust gas post treatment system for nitrogen oxide and particle reduction of internal combustion engines operated with excess air. An oxidation catalytic converter is disposed in the exhaust gas stream of the engine for converting at least a portion of the nitric oxide in the exhaust gas into nitrogen dioxide. The first particle separator or filter is disposed in the exhaust gas stream downstream of the oxidation catalytic converter for converting carbon particles accumulated in the separator or filter into carbon monoxide, carbon dioxide, nitrogen and nitric oxide with the aid of nitrogen dioxide contained in the exhaust gas. A partial exhaust gas stream is branched off from the exhaust gas stream upstream of the first separator or filter. A metering device adds reduction agent to the partial exhaust gas stream in the form of ammonia or a material that releases ammonia downstream of the supply location due to hot exhaust gas. A second particle separator or filter is disposed in the partial exhaust gas stream downstream of the supply location. The partial exhaust gas stream returns to the exhaust gas stream downstream of both particle separators or filters. An SCR catalytic converter is disposed downstream of the return location for reducing nitrogen oxides in the exhaust gas to nitrogen and water vapor with the aid of ammonia or released ammonia by way of selective catalytic reduction.

Device for administration of nitric oxide to horses spontaneously breathing
The present invention is directed to a nitric gas dispenser for mammals on the run. The dispenser has a housing that contains a valve mechanism. The valve mechanism is interconnected between a nitric gas dispersal component that provides nitric gas at a desired pressure and a gas delivery system that provides the nitric gas at the desired pressure to the mammal. The valve mechanism controls the flow of the nitric gas between the nitric gas dispersal component and the gas delivery system. The dispenser also has a pressure sensor that is positioned along the gas delivery system and determines when the mammal is taking a breadth. If the pressure sensor determines the mammal is taking a breadth, the pressure sensor transmits a breadth signal to a microprocessor. The microprocessor then determines if the mammal is within a prescribed time frame for the mammal to be administered nitric gas. If the microprocessor determine the mammal is within the prescribed time frame, the microprocessor transmits an open signal to the valve mechanism to release a predetermined amount of nitric oxide gas to the mammal.

Intermittent dosing of nitric oxide gas
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.
