Apparatus and method for measurement of the elasticity of a macroscopic sample

摘要

Shown is a device for measurement of the elasticity of a macroscopic sample, in particular for measuring the elasticity of the tissue of a living human or animal, comprising: at least one outlet for a fluid jet and / or an inlet for sucking in a gas stream, means for positioning the apparatus in such a way in relation to the macroscopic sample, that the outlet and / or the inlet and / or an end face of the device in a predetermined or by the said means which can be determined distance from the macroscopic sample is located, and means for measuring a size, the characteristic for the degree of deformation of the sample due to an interaction of the sample with the fluid jet and / or the incoming fluid flow, whereby this size by means of an ion current in the deformation region of the sample, or the volumetric flow of the fluid itself or – for the case that the fluid through the elastic sample is enclosed by a change in volume and the associated change in pressure in the enclosed fluid, is determined.
