METHOD FOR INFRARED VISUALISATION OF FOREIGN MATTERS IN HAND

摘要

FIELD: medicine.SUBSTANCE: invention refers to medicine and can be used for the infrared visualisation of foreign matters in a hand. The hand is exposed, and the arm is circularly compressed above the hand until arterial pulse disappears on the periphery. The hand is immersed in water at temperature +25 - +26°C for 3-10 seconds. The hand is taken out from water and placed with its desired plane onto a flat persistent heat emitter at temperature +42°C made of a high-thermal conductivity material. The hand is fixed in a position to perform the infrared visualisation of a surface opposite the hand plane by means of a thermal imaging device. That is followed by recording a local temperature flow of this ischemic plane. What is used is a thermal imaging device having capable to image the examined surface on a display in red to purple colours depending on its local temperature within the range of +26 - +37°C respectively. If the hand appears to have abnormal local hypo- or hyperthermia, its zone is shaped, sized and localised. If the abnormal hypo- or hyperthermia zone is absent, the examination is repeated not earlier than 5 minutes later by changing a sequence of using the hand planes.EFFECT: method provides more effective, safe and accurate detection of the foreign matters, including for performing sparing surgical operations on dry hand, with eliminating high blood loss.1 ex
