Inventor: MELZNER EDGAR
IPC: A47L9/04
Filed: 1998-06-12
Granted: 1999-11-04
Abstract: The cleaner has a turbine chamber (2) with an air inlet opening (12) for suction air flow. The vacuum cleaner has a housing (71) with a connection port (78) for air flow connection to the vacuum mechanism, a brush roller (74) near the suction opening (73) with brushes (75) protruding through the opening when in the lower position, and an air turbine (3) driving the roller. The turbine is mounted in a turbine chamber and acted upon by the suction air flow (20). The turbine chamber (2) has an air inlet opening (12) for the suction air flow. When the power required by the roller reduces, the air turbine moves axially with respect to the inlet opening so that the brush roller's revolution rate decreases.

Abstract: FIELD: medicine, toxicology. SUBSTANCE: in contrast to a prototype in suggested method burn toxins are removed from skin surface by constant washing it with physiological solution that enables to use this method during the whole period of burn intoxication. Exchange of solutions 4-10 times daily maintains the concentration of toxic substances in washing solution at low level that leads to their constant and prolonged washing out from injured tissues due to diffusion and, correspondingly, to decreased toxemia. Turbulent flow of solution at its substitution favours an active spare mechanical cleaning of injured surface against necrotic masses. Liquid layer isolates injured surface against microbial contamination. Addition of water-soluble antibacterial preparations into solution decreases the danger of burn infectious complications. EFFECT: pronounced decrease of toxemia and increased viability of patients at extensive burns.
