Considering now the operation and application of the device 10 in practicing the improved method, the reservoir 20 is filled with water or an aqueous solution containing any desired solutes or dispersants through the open lid 34, which is then closed. The finger piece 29 is then adjusted to vary the opening of the by-pass valve from passageway 22 into reservoir 20 and thereby adjust the jet velocity and pulse frequency. The rubber ring carrying end opening of shield 77 is pressed against the skin, for example, the facial skin, to surround the area to be treated and effect a liquid tight seal between the shield and the skin and the motor energizing swith is then closed. The piston 56 is reciprocated by the energized motor by way of transmission 60 to draw liquid during its downward suction stoke from reservoir 20 by way of the suction-opened check valve 52 and to urge the liquid through the upward pressure stoke of piston 56 through the orifice 84 as a sharp jet. The pulsating liquid jet impinges on the skin delineated by the ring 89 and flows back through shield 87 and drain pipe 88 into reservoir 20 where it may be recirculated. It has been found that a highly effective treatment is achieved by exposing the confined area of the skin to the pulsating jet of the above frequency and at a velocity just below an uncomfortable pain level for a period of 20 to 40 seconds duration.
While there have been described and illustrated preferred embodiments of the present invention, it is apparent that numerous alterations, omissions and additions may be made without departing from the spirit thereof.
I claim:
1. A massage device comprising a liquid confining shield member having an opening at its distal end and a drain opening, a nozzle directed through said shield member toward said distal opening, a liquid reservoir, and means for producing a pulsating liquid flow from said nozzle and including a positive displacement intermittent pump having an outlet communicating with said nozzle and an inlet communicating with the lower part of said reservoir, said drain opening communicating with said reservoir.
2. The massage device of claim 1 wherein the pulse frequency of said liquid pulsating means is between 2,200 and 3,200 cycles per minute.
3. The massage device of claim 1 comprising a hollow handle member having said liquid reservoir therein, the shield member being mounted proximate the top of said handle member and having a drain opening therein, rearwardly of said distal opening, and an electric motor housed in said handle member and drive coupled to said pump.
