A Thermoelectric Device to Stop Bleeding

Resumo

The design of a device for stopping bleeding is considered, in which the operative element is a thermoelectric battery (TEB) operating in cooling mode until the moment at which bleeding stops and in heating mode when the device is removed from the damage site. A model of the device based on solving the problem of thermal conductivity on phase transition is proposed. Numerical experimental results yielded a relationship between the time taken to form solid-phase blood 3 mm thick and the power and supply current of the TEB at different blood flow pressures in the wound zone. The device can use a standard TEB with power consumption of 40_80 W depending on the area of blood flow for procedures lasting 7-8 min.
