Nitric oxide (NO) accumulation apparatus

An NO-accumulation apparatus for accumulating NO in a liquid, comprising:

• a container defining a cavity for accommodating the liquid, an inlet for feeding the liquid into the container and an outlet for delivering the liquid from the container to a bath unit;
• an NO-gas dissolving unit for dissolving gaseous NO in the liquid to produce an NO-containing liquid, wherein the NO-gas dissolving unit is arranged in the container and/or forms a part of the container;
• and
• an NO-gas port in fluid communication with the NO-gas dissolving unit, said NO-gas port being adapted to couple with an NO-gas supply;
• and
• first decoupling means for decoupling an inflow of NO-gas to the liquid within the container and second decoupling means for decoupling removal of the NO-containing liquid from the container;
• wherein the first and second decoupling means are mechanically, electrically or electronically coupled such that the inflow of the NO-gas to the liquid within the container is inhibited when the NO-containing liquid is being removed from the container and such that removal of the NO-containing liquid from the container is inhibited when NO-gas is flowing into the liquid in the container.
