FIELD: medical engineering. SUBSTANCE: provision is made in device construction for metallic coating, auxiliary transparent cupola with evacuated gap, and auxiliary ventilation system. Reflecting coating peculiarities are in that cupola walls along with reflecting coating have insignificant value of blackness degree for infra-red radiation and high value of transparency coefficient in visible radiation spectrum. EFFECT: thermal losses are ten times less, minimum power consumption. 7 cl, 8 dwg
