An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

Systems, products, compounds, and methods can be applied and/or used by a person to facilitate and promote the production of nitric oxide to be used by a person for health benefits. The systems, products, and devices include a nitric oxide bath system. The systems and methods can comprise one or more compounds that when mixed are adapted to produce nitric oxide gas, with at least one nitrite compound and at least one acid compound. The nitric oxide gas may then be delivered to a user transdermally via one or more bath applications.

A manifold for an air massage system of a tub may have a housing defining an inner cavity having an air inlet configured to be pneumatically connected to a pressure source. Air outlet(s) is pneumatically connected to one or more outlets of the tub. A check valve(s) is in the inner cavity of the housing, the at least one check valve being positioned between the air inlet and the at least one air outlet relative to an air flow through the housing, the at least one check valve allowing fluid communication from the air inlet to the at least one air outlet and blocking water from flowing from the at least one air outlet to the air inlet. A width of the manifold is less than a height of the manifold.

A shower head includes a handle and a head portion. The head portion includes shower holes. The handle includes an upstream bubble generator that generates minute bubbles in water. The head portion includes a downstream bubble generator that generates minute bubbles in water in the same manner as the upstream bubble generator. The upstream bubble generator includes a constriction and a tapered portion. The downstream bubble generator has a swirling flow mode. Since minute bubbles are generated on the upstream and downstream sides, the amount of minute bubbles mixed in water becomes larger. This allows for showering by effectively using the function of minute bubbles.

A dispenser (1) of liquids for medical uses wherein a first membrane body (10) is shaped symmetrically with respect to a first frontal median plane (M) and to a second sagittal median plane (N) intersected in a central axis (A) and is delimited at the top by a dome (12) which is axially delimited by a base portion (12′) and by a top (12″) of given shape; a second body (20) being carried by the first body (10) inside the dome (12) in a position concentric with the axis (A); the second body (20) having a hollow lower portion (22) concentric with the axis (A) and an upper portion (28) engaged by a first and a second duct (280) (280′) terminating in the dome (12), with a first nozzle (2800′) (2800) and a second nozzle (2800′) respectively; each first and second nozzle (2800) (2800′) being arranged between the first frontal median plane (M) and the second sagittal median plane (N).

A method for enhancing tissue oxygenation by bathing the body or part of a body in water infused with oxygenated microbubbles.

Systems and methods for nitric oxide (NO) generation systems are provided. In some embodiments, an NO generation system comprises at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas. The electrodes have elongated surfaces such that a plasma produced is carried by the flow of the reactant gas and glides along the elongated surfaces from a first end towards a second end of the electrode pair. A controller is configured to regulate the amount of NO in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller. The one or more parameters include 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 the product gas flows.
