Abstract
Abstract A suction device for cleaning skin having a suction nozzle with a plurality of openings that are covered by an elastic diaphragm which is drawn into the openings by a pulsating drive force so that the diaphragm forms a plurality of pulsating secondary vacuum pumps in contact with the skin, thus, the vacuum action on the skin is divided into short variable suction pulses and the covering elastic diaphragm offers an easily exchangeable disposable hygienic protection.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
86 words
A suction device for cleaning skin comprising: a suction nozzle having a plurality of openings; an elastic diaphragm which covers the openings; and means for generating a pulsating driving force for drawing the elastic diaphragm into the openings so that the diaphragm forms a plurality of pulsating secondary vacuum pumps in contact with the skin, wherein the pulsating drive force generating means further comprises electromagnets for generating the pulsating drive force and the diaphragm further comprises one of fine inserts and a layer of magnetic material.
Claim 2
Dependent Claim
86 words
A suction device for cleaning skin comprising: a suction nozzle having a plurality of openings; an elastic diaphragm which covers the openings; and means for generating a pulsating driving force for drawing the elastic diaphragm into the openings so that the diaphragm forms a plurality of pulsating secondary vacuum pumps in contact with the skin, wherein the pulsating drive force generating means further comprises electromagnets for generating the pulsating drive force and the diaphragm further comprises one of fine inserts and a layer of magnetic material.
Claim 3
Dependent Claim
