Abstract
Abstract A device for the measurement of the elasticity of the human skin, by which a negative pressure is created in an area of the skin up to reaching a predetermined value and the temporary deformation of the skin itself is measured; by returning the negative pressure to the zero value, the deformation of the skin in correspondence with that value is measured, i.e. the permanent deformation of the skin.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A device for the measurement of the elasticity of the skin comprising: a suction cup to be sealingly applied on a selected area of the skin where the elasticity measurement is to be made; a pressure measurement instrument connected to the suction cup; suction means, connected with said suction cup, for creating in said suction cup a negative pressure up to a predetermined value readable by means of said pressure measurement instrument and provided with measuring means in such a way that, at said predetermined value of the negative pressure, it is possible to determine the volume of air sucked by said suction means or a corresponding parameter, which is proportional to the temporary deformation of the skin in said area where the suction cup is applied and is subjected to said negative pressure, and in such a way that, by bringing said suction means back towards the start position up to a zero value of said negative pressure, it is possible to detect the volume of the possible residue of sucked air, which is proportional to the permanent deformation of the skin.
Claim 2
Independent Claim
183 words
A device for the measurement of the elasticity of the skin comprising: a suction cup to be sealingly applied on a selected area of the skin where the elasticity measurement is to be made; a pressure measurement instrument connected to the suction cup; suction means, connected with said suction cup, for creating in said suction cup a negative pressure up to a predetermined value readable by means of said pressure measurement instrument and provided with measuring means in such a way that, at said predetermined value of the negative pressure, it is possible to determine the volume of air sucked by said suction means or a corresponding parameter, which is proportional to the temporary deformation of the skin in said area where the suction cup is applied and is subjected to said negative pressure, and in such a way that, by bringing said suction means back towards the start position up to a zero value of said negative pressure, it is possible to detect the volume of the possible residue of sucked air, which is proportional to the permanent deformation of the skin.
Claim 3
Dependent Claim
98 words
A device according to claim 1, wherein said suction means are plunger-type suction means provided with a graduated scale so that, at said predetermined value of the negative pressure, the amount of the displacement stroke of the plunger of said suction means, proportional to said temporary deformation of the skin, is determined and, by pushing said plunger towards the start position up to a zero value of said negative pressure, it is possible to detect the amount of the possible residue of said displacement stroke of said plunger, which is proportional to the permanent deformation of the skin.
Claim 4
Dependent Claim
18 words
A device according to claim 1 or 2, wherein said pressure measurement instrument is a precision pressure gauge.
Claim 5
Dependent Claim
14 words
A device according to claim 2, wherein said plunger-type suction means comprise a syringe.
Claim 6
Independent Claim
28 words
A device according to any of the claims 1 to 4, wherein said predetermined value of the negative pressure is preferably comprised between 5 and 10 mm Hg.
Claim 7
Independent Claim
32 words
A device according to any of the preceding claims, wherein the sealing application of said suction cup is performed by coating beforehand said preselected area of the skin with an adhesive cream.
