DEVICE FOR SIMULATION cardiac contusion

摘要

The invention relates to an experimental medicine, namely to the pathophysiology of - play in the experiment as an isolated injury of the heart damage, allows you to explore the mechanisms of myocardial dysfunction in this disease and cost-effectiveness of metabolic correction. The task of a utility model - increasing the fidelity of heart injury due to the ratio of the force of impact and accuracy hitting the severity of traumatic object in the projection of the heart, as close as the most frequent mechanism of injury producing heart and its isolation from other organs. The problem is solved by the use of the device for simulating cardiac contusion, consisting of a working surface for fixing the experimental animal, which is used as a rat, and the hammer. Experimental animal fixed horizontally on the desktop, thus placing a circular metal plate 2 mm thick and 2.5 cm in diameter in the area of the projection of the heart as well as a percussion mechanism using a pneumatic gun having a specific impact energy of 0.12 J / cm ^2, fixed on a rack so that the muzzle of the gun rests against the plate.
