THERMOELECTRIC DEVICE FOR ARREST OF HEMORRHAGE Russian patent published in 2016 - IPC A61F7/00 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, particularly to means for arrest of hemorrhage. Device contains source of cold which is brought into thermal contact with region of haemorrhage, consisting of thermoelectric battery fed by source of electric energy, working surface conjugated with heat equalising plate, which surface in contact with object of exposure, has layer of elastic material, opposite working surface of which is brought into thermal contact with heat removing plate made hollow and filled with substance having higher heat of fusion and melting point, lying within 30-45 °C. Fixing device is made up of two strips of leather or fabric from one side fixed on sides of heat equalising plate, and on other side having possibility of connection in form of Hook and Loop latch. Heat equalising and heat removing plates are interconnected by fasteners made of material with low coefficient of thermal conductivity so that heat equalising, heat removing plate and thermoelectric battery can form rigid structure. Source of electric power is made with possibility to feed thermoelectric battery short-time current pulse of opposite polarity after arrest of hemorrhage.

EFFECT: use of device during effect on bleeding area enables higher intensity of cooling, thus reducing duration of thrombosis, stopping blood flow.
