Plasma disinfection device, medical transfer bed and positive and negative pressure isolation conversion method

The invention discloses a plasma disinfection device for a medical transfer bed, and relates to the field of medical equipment.The plasma disinfection device for the medical transfer bed comprises an air inlet, a primary filter, a draught fan, a plasma disinfection unit, activated carbon, a high-efficiency filter and an air outlet; the air flow sequence is the air inlet, the primary filter, the fan, the plasma disinfection unit, the activated carbon, the high-efficiency filter and the air outlet in sequence; when the plasma disinfection device for the medical transfer bed works in a negative pressure isolation mode, airflow sequentially comprises the air inlet, the high-efficiency filter, the fan, the plasma disinfection unit, the activated carbon, the primary filter and the air outlet. The plasma disinfection device for the medical transfer bed can realize conversion from positive pressure isolation to negative pressure isolation, or conversion from negative pressure isolation to positive pressure isolation,
