A device for preparation to tests of units of lower extremities stumps relates to medical equipment, namely to prosthetics and prosthetic device construction, and can be used for static and cyclic tests of functional units of lower extremities stumps. The device comprises the upper and the lower levers with supports and clamps for installation of test samples of extremities stumps, holder for test sample installation and the base attached to the vertical rack on it, and on the stand by means of pins a template with four holes are installed to set supports, the template contains horizontal bar with scale, which is installed with the possibility of movement in the horizontal plane by one end in its holder for installation of the test sample and by the other end in the cylindrical clamps, stopper, which is by contact way connected with the bar, the coordinates of position on the template of the first and second pair of holes are determined in accordance with conditional axis coordinate values of the resulting load acting on the node under test, respectively in the first or second testing schemes. The device allows to determine with high accuracy the conventional line for application of loads and thus to expand the range of knee functional units to be tested for static and cyclic strength. |
