Burns are already a real morbidity and mortality issue even though developments on treatment modalities and physiopathology. Therefore various types of burn models have been used in experiments. The time parameter in was limited in experimental burn models however real time pressure and temperature were ignored as if they are standard. In this study we present a new burn model apparatus in which the real time temperature and pressure could be documented without personal or locational differences.
The apparatus has been consisted of four units. A ring shaped resistance with a 280 watts of power for heating. The electronic scale was used for pressure. A 10 mm diameter cylinder shaped cupper bar was used for burn surface. A spring-loaded mechanism was fixed on a stainless steel not to waste time during the experiment. An electromechanical high sensitive control thermocouple with PID control ability was placed at the center of the bar for real time temperature measurement. For controlling the voltage and current of electricity another unit was manufactured.
There were no difference between the depths of healthy full thickness skin, dermis and epidermis. A 9°C temperature gap was observed between the contact surface and inner side. The differences of burn depths in all four groups were significant (p=0.0125, p=0.0001, p=0.0001, p=0.0001). Besides, pressure applied on the skin is significant as much as the temperature of the bar.
As a result, in an experimental burn model, the pressure is a significant factor as much as temperature and elapsed time. Furthermore, standardization in a burn model, could be obtained just under the control of all parameters, as was in our custom designed apparatus.
