A therapeutic device for applying pressure to a portion of a wearer's body is provided. The device includes a flexible enclosure formed from a flexible material and configured to enclose at least a portion of the wearer's body, thereby forming a cavity between an inner surface of the enclosure and the body. The device also includes at least one port extending through the flexible enclosure for accessing the cavity; and a fluid evacuation pump in fluid communication with the cavity. The device is configured such that, upon actuation of the pump, the flexible enclosure transitions from a relaxed position to a compressed position, in which the flexible enclosure exerts a compression force against the wearer's body. Optionally, the flexible enclosure defines a cross sectional area, wherein the cross sectional area in the relaxed position is greater than the cross sectional area in the compressed position.

Adjustable seating devices for use in a hot tub are disclosed. Example adjustable seating devices, as disclosed herein, may include multiple panels that move relative to one another and/or relative to the hot tub frame to adjust between positions. In some embodiments, one or more panels of the disclosed adjustable seating device may include jets. The disclosed adjustable seating devices may be adjusted manually, hydraulically, air-actuated, or electronically.

A liner for containing a soaking solution in use with a foot spa features two bodies of plastic which are joined at an interface therebetween so as to form two, individual layers. An air conduit is formed between the two layers so as to provide a passageway for pressurized air, which is supplied by an air discharge apparatus, across walls of the liner and into the soaking solution. The inner layer has openings such that the air guided through the air conduit can be released into an inside volume of the liner where the soaking solution is containable. Furthermore, the outer layer is imperforate from a location thereon at which a starting end of the air conduit is disposed to a free end of the layers so as to isolate the inside volume of the liner from the soaking basin.

A tub comprising a body for holding a volume of water. A tub system is coupled to the body to perform a function on the volume of water. At least a first circuit has a first circuit portion comprising at least one resistive switch mounted to a visible surface of the body and comprising at least a first resistive element adapted to be contacted by a bather, second circuit portion comprising a water detection sensor mounted to the body for containing liquid in the body above a given level, the first circuit being open between the first resistive element and the water detection sensor, an actuating closed circuit condition by which a bather in liquid above the given level closes the first circuit between the first circuit portion and the second circuit portion when touching the first resistive element. A controller is operationally coupled to first circuit portion and the second circuit portion of the first circuit, and to the tub system, the controller adapted to detect the actuating closed circuit condition to trigger an action of the tub system.

The present disclosure is generally directed towards an ultrasonic showering device. The ultrasonic showering device includes a head portion including a plurality of nozzles that dispense a fluid, a movement component that detects movement of the head portion, and an ultrasonic transducer that generates and transmits ultrasonic energy. The ultrasonic showering device includes a handle portion including a controller that operates the ultrasonic transducer based on the movement component.

A hot tub hybrid power system includes a connector and at least one battery. The connector is configured to receive AC power from an external source at a first power level. The at least one battery is in combination with a DC to AC power transformer configured to output AC voltage at a second power level. A combiner/regulator is configured to selectively output power at the first level, the second level, or a combination of the first and second level based on a state of a hot tub.

A spa includes a shell having at least one cavity, the spa shell being configured to hold a volume of water, at seat insert having a plurality of hydrotherapy jets, the seat insert being received in the at least one cavity and defining a space between the seat insert and the shell, and a drain associated with the at least one cavity for removing water from the space between the seat insert and the shell.
