Embodiment 1

[0027] A disinfection method for class III clean operating room, including the following steps:

[0028] (1) Clean the operating room, spray the floor and walls with ethanol, and then dry the floor and walls with nitrogen containing ozone;

[0029] (2) Sterilize the airtight operating room with a low-temperature plasma sterilizer, use hydrogen peroxide to generate plasma, and sterilize the operating room with a hydrogen peroxide dosage of 0.1ml / m3 for 20 minutes;

[0030] (3) After sterilization, turn on the ultraviolet sterilization lamp in the operating room to irradiate for 5 minutes. The ultraviolet source wavelength of the ultraviolet sterilization lamp is 250nm, and the ultraviolet intensity is not less than 50μW / cm2. Keep the air flow in the operating room during the irradiation;

[0031] (4) Turn on the air change function of the air conditioning system in the operating room to replace the air in the operating room.

[0032] In the step (1), the operating room is cleaned and the...

Embodiment 2

[0039] A disinfection method for class III clean operating room, including the following steps:

[0040] (1) Clean the operating room, spray the floor and walls with ethanol, and then dry the floor and walls with nitrogen containing ozone;

[0041] (2) Sterilize the airtight operating room with a low-temperature plasma sterilizer, use hydrogen peroxide to generate plasma, and sterilize at the amount of hydrogen peroxide at 0.15ml / m3 for 23 minutes;

[0042] (3) After sterilization, turn on the ultraviolet sterilization lamp in the operating room to irradiate for 8 minutes. The ultraviolet source wavelength of the ultraviolet sterilization lamp is 253nm, and the ultraviolet intensity is not less than 50μW / cm2. Keep the air in the operating room flowing during the irradiation;

[0043] (4) Turn on the air change function of the air conditioning system in the operating room to replace the air in the operating room.

[0044] In the step (1), the operating room is cleaned and the operating r...

Embodiment 3

[0051] A disinfection method for class III clean operating room, including the following steps:

[0052] (1) Clean the operating room, spray the floor and walls with ethanol, and then dry the floor and walls with nitrogen containing ozone;

[0053] (2) Sterilize the airtight operating room with a low-temperature plasma sterilizer, use hydrogen peroxide to generate plasma, and sterilize with 0.2ml / m3 of hydrogen peroxide for 25 minutes;

[0054] (3) After sterilization, turn on the ultraviolet sterilization lamp in the operating room to irradiate for 10 minutes. The ultraviolet source wavelength of the ultraviolet sterilization lamp is 255nm, and the ultraviolet intensity is not less than 50μW / cm2. Keep the air flow in the operating room during the irradiation;

[0055] (4) Turn on the ventilation function of the air conditioning system in the operating room to replace the air in the operating room.

[0056] In the step (1), the operating room is cleaned and the operating room temperatur...

Abstract

A III-grade clean operating room sterilization method includes steps: cleaning an operating room; adopting a low-temperature plasma sterilizer for sterilization in a closed environment after cleaning is finished, turning on ultraviolet sterilization lamps in the operating room to irradiate; starting a ventilation function of an air conditioning system of the operating room to change indoor air of the operating room. Ethyl alcohol is sprayed to an indoor floor and walls of the operating room, and then ozone-containing nitrogen is adopted for blow drying to finish primary sterilization of the operating room; after primary sterilization is finished, the low-temperature plasma sterilizer is adopted for sterilization; after sterilization, residual viruses are killed under irradiation action of the ultraviolet sterilization lamps. By reasonable control of indoor temperature and humidity in each step, bacterial and viral activity is reduced, and sterilization effects are improved. After the operating room is sterilized according to the sterilization method, detection is performed until each index accords with III-grade clean operating room requirements.

Description

Technical field [0001] The invention relates to the technical field of disinfection and purification of operating rooms, in particular to a method for disinfecting a Class III clean operating room. Background technique [0002] Operating room (O.r in English abbreviation) is a place that provides surgery and rescue for patients, and is an important technical department of the hospital. The operating room should be connected to the operating department, but also close to the blood bank, intensive care unit, and anesthesia recovery room. Grasp the management of the four pathways of surgical incision infection, namely: the air in the operating room; the items needed for the operation; the fingers of doctors and nurses and the patient’s skin to prevent infection and ensure the success rate of the operation. It is required to have reasonable design, complete equipment, responsive, fast and efficient work efficiency. The operating room must have a set of strict and reasonable rules a...
