DEVELOPMENT OF A DEVICE FOR THE DETECTION OF NON-X-RAY CONTRAST FRAGMENTS IN THE WOUNDED AFTER BURNT INJURIES

Abstract

Introduction. Since the injury often occurs not only with radiopaque fragments and bullets, the diagnosis of the position of foreign bodies in the wound channel or the patient's cavity is complicated. In the conditions of modern conflict, new types of weapons and striking projectiles are used, and new materials, in particular modifications of plastic, are increasingly used as bullets, projectile shells, and offensive and defensive grenades. Cases of splinter damage to soft tissues by plastic and glass elements are increasingly common. Plastic, getting into the human body's soft tissues, has the properties of the cores of bursting bullets, significantly increasing the size of the pulsating cavity of the wound channel. At the same time, the ability of plastic and glass to shatter in the body may require opening wounds to treat and remove these foreign objects, increasing the trauma and prolonging the rehabilitation period of patients. Searching for a fragment, especially a non-radiocontrast one, in the wound channel is often difficult and long, which is associated with its insufficient visualization, a change in the normal anatomy in gunshot wounds, and the difficulty of the surgical search. Therefore, the search for simple and reliable means of diagnosing foreign objects in the patient's body (without the use of X-ray machines) in the field is an urgent and extremely important task today, the solution of which can save the lives and health of thousands of wounded.

Conclusions. The article describes the prerequisites for the development of a new method of diagnosing the presence of extraneous non-contrast fragments in a patient's wound through direct contact. The use of the noise emission effect is described for the detection of fragments. Due to the difference in noise, it is possible to tactilely diagnose the location of the fragment. After experimenting with the biological model, it was possible to record the dependence of the amplitude and base frequency of oscillations depending on the position of the fragment and its size in the wound channel. The article also provides an example of an effective pain relief scheme when searching for fragments.
