A device and a method for simultaneous recording, in real time, of the parameters characterising the mechanical tension, elasticity, dynamical stiffness, creepability and mechanical stress of soft biological tissue is 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. The 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, the time span on the graph is used which involves the oscillation period from the beginning to the end of the effect on the tissue plus its subsequent first 1.5 self-oscillation period. Invention enables recording and data-processing to be carried out simultaneously as well as statistically significant estimates to be made in real time. |
