The present invention relates to the technical field of massagers, and discloses a multipurpose thermostatic underwater massager, which includes a thermostatic principal machine, a duct switch for controlling output of gas flow, a cushion, an air outlet duct, an air outlet handle, and a first soft duct and a second soft duct for conveying gas flow. The duct switch is installed at the air outlet of the thermostatic principal machine, and the first soft duct and the second soft duct are respectively connected with the two outlets of the duct switch. The outlet of the second soft duct is communicated with the cushion, and the two ends of the air outlet duct are respectively communicated with the front and back of the cushion.

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.

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.
