A SPA pool is provided including a pool body, the pool body including a pool bottom and a pool wall together defining a water cavity. The SPA pool further includes: an inflatable seat defining therein a second air chamber and disposed in the water cavity; a first nozzle assembly, wherein at least a part of the first nozzle assembly is accommodated within the inflatable seat, and a first end of the first nozzle assembly is in fluid communication with the water cavity. The pool body further includes a fluid pipeline disposed in the first air chamber, the fluid pipeline being in fluid communication with a second end of the first nozzle assembly, so that the first nozzle assembly provides fluid communication between the water cavity and the fluid pipeline.

An apparatus, system, and method involving controlling a spa system having a basin are provided. In one embodiment, the apparatus or system includes an electronics control portion and smart embedded software for receiving inputs from an operator of the spa system and for generating signals in response to inputs received from the operator. In addition, the apparatus or system includes a fluid mixing portion that receives the fluid from a supply and outputs the received fluid into the basin of the spa system. Moreover, the electronics control portion reads a temperature of the fluid in the fluid mixing portion and displays it to the control keypad. In another embodiment, the system includes a pump having a contactless, water sensor for dispensing water or air to a setting and for use with a disposable liner. The pump includes a jet assembly, a motor assembly, and a contactless, water sensor.

Systems, devices, and methods for treating wounds and infections by immersion therapy are provided along with methods for the use thereof. The systems and devices may include a basin and a heater-blower apparatus. The systems and devices aerate, agitate, and slow the cooling of a liquid in the basin to aid the blood-flow, debridement, and medication of a wound or infection.

This invention relates to a portable bath and hydrotherapy apparatus, utilizing an electric or a battery-operated motor. More particularly, the invention relates to a portable hydrotherapy unit which can be used in conjunction with a bathtub or with other open-topped bodies adapted to be partially filled with a supply of liquid. The improved resultant of the present invention is the utilization of such a motor for hydrotherapy purposes whereby the unit re-circulates the water of the bathtub.

Dispenser (1) for liquids comprising an applying nozzle constituted by a bell-shaped body (2) extending along a central axis (A) and provided, at the bottom, with an annular collar (3) and, at the top, with a convex cap (4); the bell-shaped body (2) having a first axial hole (5) whose cross-section decreases from the collar (3) towards said cap (4); a valve (7) for nebulizing the solution being housed inside the first hole (5) in a matching manner; an expansion device (9) being provided at the exit of said first hole (5).

A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.

Systems, apparatus and methods for providing air and water to hot tub jets. The present teachings include jet assemblies, manifold assemblies, and related components, as well as methods of assembling hot tubs involving these components. In some cases, the present teachings describe the use of dual extrusion tubing to route air and water through adjacent, connected fluid conduits. In some cases, the present teachings describe a press-and-click method of connecting various components.

A jet nozzle includes a single-piece body having a water inlet with a first inlet channel coaxial with a first inlet axis, a gas inlet with a second inlet channel coaxial with a second inlet axis, and an outlet coaxial with an outlet axis, the single-piece body defining a fluid passageway from the first inlet channel to the outlet. A channel wall having a water channel is positioned in the fluid passageway between the first inlet channel and the outlet, the water channel being coaxial with the outlet axis and having a diameter that is smaller than a diameter of the first inlet channel. The second inlet axis is substantially perpendicular to and intersects the outlet axis at a point within the water channel.
