The present invention is about pressure steam self disinfection, which is characterized in that, in addition to its tool disinfection function in the main camera, the second or third disinfection camera is allowed to exchange and seal with each other, It is stored in the high-pressure water pump and quickly connected to the main disinfection room to enter the internal parts of the high-pressure water pump, such as compressor, water heater, electric valve, etc,In order to disinfect the sanitary waste and water vapor or ozone gas vapor without polluting the main cabin, two or three completely autonomous and separate cameras are obtained. The current invention is a self checking method of operation, which reports through weight sensors that have checked the kilogram on their legs, as well as all their internal parameters through a gprs-sim electronic board.La presente invencion se refiere a una autoclave de vapor a presion, la cual esta caracterizado por que ademas de hacer sus funciones de esterilizacion de instrumental en la camara principal, permite que a una segunda o tercera camara esterilizadora intercambiable y hermetica, alojarla en el interior de la autoclave y conectarla por medio de un enganche rapido a la camara principal de esterilizacion y de esta manera acceder a los componentes internos del autoclave como compresores, calentadores de agua, electrovalvulas, etc., para esterilizar los residuos sanitarios sin contaminar la camara principal con vapor de agua o gas ozono, logrando obtener dos o tres camaras completamente autonomas y separadas. La presente invencion se refiere a un metodo de operacion de la autoclave donde esta reporta los kilos tratados por medio de unos sensores de peso en sus patas, asi como todos sus parametros internos a traves de una placa electronica GPRS-SIM.
