Abstract: An apparatus (2) for dissolving a gas into a liquid includes a liquid inlet (4) for supplying liquid into the apparatus, a gas inlet (6) for supplying gas into the liquid within the apparatus and a venturi (52) arranged to dissolve the gas into the liquid passing through the venturi. The apparatus also includes an outlet (18) for the liquid and dissolved gas downstream of the venturi. At least part of the liquid inlet, at least part of the gas inlet, at least part of the venturi and at least part of the outlet are formed in an integrally formed piece of material (42).

Abstract: The invention provides liquid formulations comprising dissolved oxygen (e.g. 10 mg/L up to 100 mg/L dissolved oxygen), and a substance which is capable of forming a gel upon contact with a body surface or body tissues, wherein said gel is capable of releasing a therapeutically effective amount of dissolved oxygen. The substance capable of forming a gel may be thermogelling and may, for example, comprise a blend of poloxamers. The liquid formulations can be applied to body tissues whereupon they form a gel suitable for the treatment of a compromised tissue, for example a wound (acute or chronic), a burn, a skin disorder (e.g. psoriasis, acne, rosacea, or other dermatological condition such as atopic dermatitis), skin sores, or tissue necrosis. The liquid formulations are also suitable for use in the prevention or treatment of a bacterial biofilm on a body surface, e.g. on the skin. The invention further provides delivery devices (e.g.
