Abstract: Systems, devices, and methods are provided for generating NO and delivering NO in controlled amounts. A system for generating nitric oxide (NO) is provided, and in some embodiments can include a converter configured to convert a source material to a NO-containing gas, at least one controller configured to independently control a conversion of the source material to the NO-containing gas and a delivery of the NO-containing gas to an inspiratory pathway, and one or more sensors configured to communicate, to the at least one controller, information related to the conversion of the source material to the NO-containing gas.

Abstract: Architectures for production of nitric oxide (NO) include systems and methods for generating NO having one or more plasma chambers configured to ionize a reactant gas to generate a plasma for producing a product gas containing NO using a flow of the reactant gas through one or more plasma chambers; a controller configured to regulate the amount of nitric oxide in the product gas using one or more parameters as an input to the controller, one or more parameters including information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which product gas flows; and a flow divider configured to divide a product gas flow from the plasma chamber into a first product gas flow to provide a variable flow to a patient inspiratory flow and a second product gas flow.

Abstract: A draining device for controlled drainage of internal water in plumbing systems comprises a semi-circular plastic collar that engages around a bottom of a pipe coupling. The collar covers the bottom of the coupling fitting and forms a watertight seal against sides of the pipe wall using an integral gasket. The collar is held in place around an upper side of the pipe using a pair of straps and strap fasteners. A hose connection fitting is provided on a bottom of the collar to provide a connection to a hose or other temporary plumbing, thereby providing drainage of water in a controlled manner.
