摘要： A device and a method for simultaneous recording, in real time, parameters characterising the mechanical tension, elasticity, dynamical stiffness, creepability and mechanical stress of soft biological tissue are provided. By means of the myometer, a constant external pre-pressure is created, independently of the device's position, between the tissue and the testing end of the device. Next, the tissue is subjected to a short-term external dynamic influence. A mechanical change in the shape of the tissue and its mechanical response are registered as a graph of the tissue's oscillations. For calculating the parameters, a time span on the graph is used which involves an oscillation period from the beginning to the end of the effect on the tissue plus its subsequent first 1.5 self-oscillation period. This enables recording and data-processing to be carried out simultaneously as well as statistically significant estimates to be made in real time.

摘要： The method and device for recording mechanical oscillations in soft biological tissues consists of the following: biological tissue is mechanically influenced by means of the testing end (6) of the device and its mechanical responses are subsequently recorded as a graph representing the evoked oscillations. Prior to that, an inflexible plane means (12) is fastened onto the biological tissue in order to designate the area under investigation and connect the testing end with the tissue, causing no harm to the latter. After that the testing end will be inflexibly connected with the inflexible plane means for the time period it takes to influence the tissue mechanically and record its mechanical response. The device consists of a frame (1), a pivotable double-armed lever (2), an electromechanical transducer (3), a shutter (4), a grip, an electromechanical pickup (5), a testing end (6), a pivot (7), a testing end driver (8, 9), a control switch (11), a control panel (10), and an inflexible plane means (12) for marking on the tissue the area under investigation and for connecting the testing end with the tissue permanently and inflexibly, causing no harm to the biological tissue. The length of the testing end (6) is adjustable by means of, for instance, a bayonet joint.
