Abstract
Abstract A confined area of skin, not exceeding about 1 1/2 sq. inches, is treated by exposing it to an aqueous jet pulsating at between 2,200 and 3,200 cycles per minute and being incident on the skin at a velocity of between 9 feet/sec. and 18 feet/sec. The massage device includes a hollow handle containing a reservoir and housing a piston pump and a drive motor. A tubular cylindrical shield extends radially from the top of the handle and has an open distal end and supports an axial nozzle at its proximate end which communicates by a passageway in the handle member to the pump cylinder and an adjustable by-pass valve connecting the passageway to the reservoir. The pump cylinder communicates with the reservoir bottom through a check valve, and the rear of the shield communicates by a drain pipe with the top of the reservoir.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
77 words
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.
Claim 2
Dependent Claim
77 words
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.
Claim 3
Dependent Claim
23 words
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.
Claim 4
Dependent Claim
54 words
The massage device of claim 1 comprising a hollow handle member having siad 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.
Claim 5
Dependent Claim
27 words
The massage device of claim 3 wherein said pump is a reciprocating piston pump having a cylinder connected to said reservoir by way of a check valve.
Claim 6
Dependent Claim
29 words
The massage device of claim 4 including a tubular passageway in said handle connecting said cylinder to said nozzle and an adjustable by-pass valve between said passageway and reservoir.
Claim 7
Dependent Claim
39 words
The massage device of claim 3 wherein said shield member is of cylindrical tubular configuration and is mounted atop and projects radially from said handle member, said nozzle being coaxially disposed at the proximate end of said shield member.
Claim 8
Dependent Claim
20 words
The massage device of claim 6 including an elastomeric annular member engaging the front peripheral edge of said shield member.
Claim 9
Independent Claim
60 words
The method of treating skin comprising confining a predetermined area of said skin by applying pressure to a peripheral border thereof, directing a liquid jet pulsating at between 2,200 and 3,200 cycles per minute at said confined area of skin, recovering the liquid incident on said skin and redirecting said recovered liquid as said pulsating liquid jets onto said skin.
Claim 10
Independent Claim
60 words
The method of treating skin comprising confining a predetermined area of said skin by applying pressure to a peripheral border thereof, directing a liquid jet pulsating at between 2,200 and 3,200 cycles per minute at said confined area of skin, recovering the liquid incident on said skin and redirecting said recovered liquid as said pulsating liquid jets onto said skin.
Claim 11
Dependent Claim
23 words
The method of claim 8 wherein the velocity of said liquid jet incident on said skin is between 9 feet/sec. and 18 feet/sec.
