  • Publication number: 20250134826
    Abstract: An example of a nitric oxide (NO) releasing film includes a substrate; an NO donor film attached to the substrate; and an NO permeable and light transparent film positioned on the NO donor film. The NO donor film includes a polymer matrix selected from the group consisting of a non-UV curable polyurethane, polyvinyl butyral, polystyrene, copolymers of styrene, block copolymers of styrene, poly(ethersulfone), polyvinylpyrrolidone, polyvinyl acetate, poly(ethylene-co-vinylacetate), and combinations thereof; and solid, light sensitive NO donor particles distributed throughout the polymer matrix. The solid, light sensitive NO donor particles have a volume-weighted mean diameter of 50 ?m or less. In one example, the NO donor film further includes an additive, such as NO2 scrubber particles, a radical stabilizer, dispersant, and/or an anti-skinning additive.

  • Patent number: 11986597
    Abstract: A moisture or hydrating liquid activatable solid formulation for nitric oxide (NO) generation includes a nitrite source; a copper (I) or copper (II) catalyst; an NO generation accelerant; and a solid pH buffer. The nitrite source is to generate NO when exposed to an effective amount of moisture or a hydrating liquid. The pH buffer is present in an amount sufficient to render a pH of the moisture or hydrating liquid activatable solid formulation from greater than 4 to about 9.0.

  • Publication number: 20200188627
    Abstract: A gas delivery device includes a nitric oxide generating system. The system has a medium including a source of nitrite ions. A working electrode is in contact with the medium. A Cu(II)-ligand complex is in contact with the working electrode. A reference/counter electrode is, or a reference electrode and a counter electrode are in contact with the medium and separated from the working electrode. An inlet conduit is to deliver nitrogen gas to the medium, and an outlet conduit is to transport a stream of nitrogen gas and nitric oxide from the medium. An inspiratory gas conduit is operatively connected to the outlet conduit to introduce an oxygen-containing gas and form an output gas stream of the gas delivery device.
