ROOM STERILIZATION METHOD AND SYSTEM

摘要

A sterilization system consisting of a mobile emitter, a sensing subsystem and a data logging subsystem is described. The emitter has one or more UV emitting lamps or devices. The sensing system comprises at least one remote UV sensor and at least one door sensor. The door sensor comprises a safety shut off door detector and may contain an emergency stop detector and arming detector to protect people from being exposed to UV energy. The system has a remote control for starting, stopping and setting system parameters which include but are not limited to: treatment time, dosage, room size, room number, unit number, floor, facility name, operator name, operator identification number, password, default dosage values, dosage, and patient identification number. The number of treatments per unit of time can be maximized because of the use of incident light measurement.

主权项

1. A tangible computer-readable medium encoding instructions for carrying out the method comprising:
accepting authentication data from a user; accepting from said authenticated user a set of disinfection job parameters, said set of disinfection job parameters comprising: a designator for a room or area to be disinfected; a desired UV dosage; a set of peripherals to be used in disinfecting said room or area, said set of peripherals comprising at least one safety sensor and at least one UV sensor; accepting a door-closed signal from a door sensor coupled to a door adjacent to said room or area to be disinfected; accepting an armed signal from said door sensor; accepting a start instruction from said authenticated user; after accepting said door-closed signal and said armed signal from said door sensor and said start instruction from said authenticated user, initiating emission of UV light from a UV emitter within said room or area to be disinfected; monitoring an intensity and a cumulative dose of UV radiation received by said at least one UV sensor; ceasing emission of UV light from said UV emitter when said desired UV dosage has been received by all of said at least one UV sensor; and indicating a finished state to said authenticated user, said method further comprising ceasing emission of UV light from said UV emitter if said door sensor indicates that said door is open or if communication from said door sensor is interrupted; ceasing emission of UV light from said UV emitter if communications from said at least one UV sensor is interrupted; and ceasing emission of UV light from said UV emitter if an emergency stop switch is activated on said door sensor.
