Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
192 words
Apparatus for washing patients hygienically with minimum disturbance of the patient comprising a closed container for a washing liquid containing a small amount of a surface-active agent, means for compressing air, means for supplying compressed air from said compressor means to said closed container in an atomized state to form a cleansing foam of the washing liquid, at least one application nozzle having outlet ports and suction ports, two flexible tubular elements, one of said tubular elements connecting the outlet ports of said at least one nozzle to said closed container for supplying foam under pressure to the outlet ports of said nozzle for application of cleansing foam to the patient''s skin, means for creating of suction, a closed collecting container, said second tubular element connecting the suction ports of said at least one nozzle to the suction-creating means for withdrawing the cleansing foam from the skin and passing it to the closed collecting container where the foam disintegrates, means for withdrawing at a predetermined pressure the gases liberated in said closed collecting container and means for heat cleaning said withdrawn gases and means for withdrawing the liquid from said collecting container.

Claim 3
Dependent Claim
39 words
Apparatus as claimed in claim 1 wherein the outlet ports are arranged about the periphery of the suction ports and further comprising a spongelike element disposed over the outlet ports for controlling the application of foam to the skin.
Claim 4
Dependent Claim
41 words
Apparatus as claimed in claim 1 wherein the suction side of said means for creating a suction is connected to the suction ports through said second tubular element and the pressure side of said means is connected to said collecting container.
Claim 5
Dependent Claim
81 words
Apparatus as claimed in claim 1 and further comprising a second nozzle having outlet ports and suctions ports, a three-way valve in said first tubular element adjacent said closed container, means for directing foam from said valve to said second nozzle, a second three-way valve in said second tubular element adjacent said suction means, means affording communication between said second three-way valve and said second nozzle, whereby said three-way valves may establish communication with at least one of said two nozzles.
Claim 6
Dependent Claim
58 words
Apparatus as claimed in claim 1 wherein the suction ports are arranged around the periphery of the outlet ports and further comprising a spongelike element disposed over the outlet ports, whereby the application of foam to the skin is controlled and the outer surface of said sponge element serves as a washing means for the surface being cleansed.
Claim 7
Dependent Claim
41 words
Apparatus as claimed in claim 5 and further comprising a ring of spongelike material disposed about the periphery of the suction ports to protect the skin area being cleansed and to assure substantially complete removal of foam from the skin area.
Claim 8
Dependent Claim
40 words
Apparatus as claimed in claim 6 wherein the spongelike element disposed over the outlet ports and the spongelike element about the periphery of the suction ports are formed as a single element which is removably attached to the associated nozzle.
