摘要: Many studies show that artificial hypothermia of brain in conditions anesthesia with the rectal temperature lowered down to 33?C produces pronounced prophylactic effect protecting from anoxia. Out methods employed now clinical practice for reducing oxygen consumption by cerebral tissue, most efficacious is craniocerebral (CCH). It finding even more extensive application cardiovascular surgery, neurosurgery, neurorenimatology and many other fields medical practice. In this study, a microcontroller-based designed human system (HBHS) constructed. The intended cooling heating brain. HBHS consists thermoelectric hypothermic helmet, control power unit. Helmet controlled 8-bit PIC16F877 microcontroller which programmed using MPLAB editor. Temperature converted 10-bit digital automatically preset values have been already entered microcontroller. Calibration working range tested. helmet between ?5 +46?C microcontroller, accuracy ± 0.5?C.
