A water massage device with entrained air is held against the region to be massaged. Mechanical displacement of the device coupled with pulsations in the water-air flow create a gentle massage. Air is entrained by passing a high velocity water jet across an air gap and through a receiving tube into a rotor chamber. Differential pressures developed in the housing establishes an air draw through the receiving tube into the housing. An eccentrically weighted rotor revolves under the impact of the jet causing the entire device to counter rotate creating the massage displacement. Each blade of the rotor developes a high pressure leading zone which sweeps away spent water. Each blade also developes a low pressure trailing zone as the blade passes the receiving tube, which favors the air draw.
This application is a rewritten continuation application of earlier filed copending application entitled "Hydro-Air Vibrator Massage Apparatus" Ser. No. 06/121,363, filed Feb. 14, 1980 by the present Applicant now abandoned .
A body massage apparatus includes a cylindrical housing mounting a rigid boss therein, with a rigid conduit extending tangentially aligned with the housing, wherein an eccentrically balanced turbine wheel is mounted within the housing to effect vibration of the housing in use. A top and bottom perforated plate are mounted and secured to the housing orthogonally to the axis defined by the housing. The invention may further include a resilient pad secured to an exterior surface of the housing to enhance use of the organization as a massage apparatus, and further including a pad utilizing massaging tips projecting exteriorly of the pad.
A massage-action shower head comprising a housing provided with a hot water entrance, a plurality of bores through which hot water is showered and a hole through which mixture of hot water and air is jetted, a first passage line formed in said housing and being capable of communicating the hot water entrance with the plural hot water showering bores, a second passage line formed in said housing and being capable of communicating the hot water entrance with the hot water jetting hole, an air introducing means provided in said housing to supply air from outside to said second passage line, and a changeover means provided under water for communicating said hot water entrance with at least one of the first and second passage lines.
A hand held hydro-suction vibration bio-stimulator submerged below the surface of a liquid in the liquid filled vessel and connected to a fluid supply by means of a flexible hose to create a periodical suction force in the range of 0.5-70 N on the frequency of 10-200 Hz and high frequency vibrations in the range of 1-20 kHz to the skin of the human body both being submerged under the surface of a liquid in a liquid filled vessel due to the passing of the fluid from the fluid supply through the hydro-suction vibration bio-stimulator.
A submergible hydrotherapy apparatus powered by an electric pump and configured to be held in user's hand for discharging a water stream underwater for massaging the user's body.
A hand held apparatus particularly configured to derive maximum energy from a tap water supply (typically, .gtoreq.20 pounds per square inch) operating at a low flow rate (typically, .gtoreq.3.0 gallons per minute) to propel a discharge orifice along a travel path while discharging a water stream of sufficient intensity to impact a user's body to provide a pleasing massage. Preferred embodiments are characterized by a handle housing and a head housing mounted for relative movement with respect to one another for operating an internal mode selector valve. The selector valve directs the supplied tap water to either a hydromassage outlet or a shower spray outlet (e.g., continuous or pulsed spray).
