A bath system comprises a tub and a fluid injection system. The tub has a jet orifice, and the fluid injection system is fluidly coupled to the jet orifice. The fluid injection system comprises a conduit, a heat source, an air supply source, and a fluid injector. The conduit has an opening. The heat source is coupled to an outer portion of the conduit external to the opening. The air supply source is fluidly coupled to the conduit, and is configured to provide a flow of air to the central opening. The fluid injector is configured to provide water to the flow of air to produce a combined flow of air and water. The heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the opening before the combined flow enters the tub through the jet orifice.

A water distribution system for providing multiple bathing functions independently for a walk-in bath tub using one pump that delivers pressurized water to a first valve having a first outlet for communicating pressurized water to a second valve and a second outlet for communicating pressurized water to a drain, the second valve selectively positioned for communicating pressurized water selectively to a respective piping system for a micro bubbles bathing function and for a pressurized jet bathing function, and a controller for moving the valves selectively to provide three operational bathing functions independently with the one pump. A method for providing multiple bathing functions independently with one pump is disclosed.

An air pump for dispensing air massage therapy to a basin is provided. It may be used and with a disposal liner. The air pump includes a motor, an air generator, a mounting housing member, a gasket or seal, and an air nozzle. The air pump assembly includes the air pump and the air dispenser. The air pump preferably also includes a printed circuit board (PCB), a PCB cover, an LED light, an infrared light, and a contactless fluid sensor. The present invention is also directed to a pump apparatus that includes an air pump as described, a power source, and/or a control apparatus.

A nitric oxide repletion system in accordance with an embodiment of the present technology may disperse therapeutic constituents into a reservoir holding a body of liquid. The nitric oxide repletion system may comprise a reservoir, and a liquid circulation system for generating a fluid flow comprising a pump, a main liquid conduit, a venturi injector, an ultrafine bubble (UFB) generator, a main return, a nitric oxide dispensing system and a mineral dispensing system. The nitric oxide repletion system may further comprise a control panel. In some embodiments, the nitric oxide repletion system may further comprise a gas supply and a gas injector system for supplying a desired gas to the venturi injector or the UFB generator.

The kids portable pedicure spa is light weight and has a flexible handle for easy traveling. The spa can be battery operated or can use the electric cord and plug to power the jets for the bubbles action and to activate the water heating system. The power to the spa is easily controlled by using the on and off switch located on the side of the tub bowl. The spa comes with two removable soft and extendable foot rest pads that adjust for length desired. There are built in storage compartments located on the outer side walls of the tub bowl that can hold nail polish, cotton ball, Q-tips and other nail accessories for convenience. The light weight tub bowl makes for easy use and clean up when filling the bowl with water and disposing of the water when finished using the pedicure spa.

A footbath has a base member defining a platform. A flexible continuous side wall extends from a proximal end region connected about a periphery of the base member to a distal end region. The side wall has a collapsed position and an extended position. The platform of the base member and the side wall cooperate to define a bath chamber for retaining water with the bath chamber sized to receive a body part. A retention member is supported by the base member to extend from the base member to the distal end region of the side wall to retain the side wall in the extended position.

A bathwater circulating system has a pump operable to draw fluid in at an intake port and expel it under pressure at an output port. Water- and air-supply conduits feed water and air to the intake port at a rate determined by a flow-restricting air-intake valve so that the pump mixes the water and the air, pressurizes the mixture and thereby dissolves the air in the water, and expels the air/water mixture at the output port. A pressure-reducing valve is connected by an output conduit that extends from the output port to the pressure relief valve and conducts the water/air-bubble mixture from the pump to the pressure-reducing valve without separation of the air from the water and such that the mixture is at least partially depressurized at the pressure-reducing valve such that the air forms microbubbles in the water.
