Hospital supply room hydrogen peroxide low temperature plasma harmful gas monitoring alarm related requirements
Hydrogen peroxide, chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid that is miscible with water in any proportion. It is a strong oxidant. The aqueous solution is commonly called hydrogen peroxide and is a colorless transparent liquid. Its aqueous solution is suitable for medical wound disinfection and environmental disinfection and food disinfection. Under normal circumstances, it will slowly decompose into water and oxygen, but the decomposition rate is extremely slow, and the speed of the reaction is accelerated by adding a catalyst such as manganese dioxide or the like, or irradiating with short-wave radiation.
Oxidation and reduction in different cases. Used for photographic decontaminants; color positive blue thinning; film over-scale thinning. Very easy to break down, not easy to save
Ander volume hospital supply room dedicated hydrogen peroxide leak alarm product features _______________________________________________________________________________________
Ander's amount of hydrogen peroxide leakage over-standard alarm is andeil sensor) combined with many years of experience in sensor core technology development, comprehensive medical, medical, supply room and other environments for hydrogen peroxide leakage residual concentration exceeding the standard monitoring alarm requirements, a fixed design for research and development Online liquid crystal display type hydrogen peroxide gas over standard alarm (also known as hydrogen peroxide sensor module probe). The output signal is 4-20mA signal or RS485, and is compatible with control systems such as alarm controller, PLC, DCS. Ander's gas detector adopts imported sensors from abroad, with fast response, high measurement accuracy, stability and good repeatability. Optional programmable switch signal output for easy linkage with other relay exhaust system fans. This product is a custom-made product, and also supports output signal trimming and other functions. Convenient system networking and maintenance.
The use of hydrogen peroxide is medical and daily disinfection is medical hydrogen peroxide. Medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci, and pathogenic yeast, which are generally used for surface disinfection of objects. Hydrogen peroxide has oxidation,
However, the concentration of medical hydrogen peroxide is equal to or lower than 3%. When it is wiped to the wound surface, there will be a burning sensation, the surface will be oxidized into white and bubble, and it can be washed with water. After 3-5 minutes, the original skin color will be restored.
3% hydrogen peroxide (medical grade) for wound disinfection;
Low temperature plasma sterilization range and precautions for hydrogen peroxide
1. Hydrogen peroxide low temperature plasma sterilization equipment and consumables Volume: total volume 173L, effective volume 100L. Sterilization speed: 55-72 minutes. Sterilization temperature: 45 ° C ~ 55 ° C. Sterilization cycle: double cycle enhanced sterilization technology. Sterilizer type: card type single-capacity single-cycle precision release device; 58% hydrogen peroxide; 1.8ml hydrogen peroxide per sterilization cycle; sterilant dosage error < 3% between single cycles.
2. Non-applicable hydrogen peroxide low temperature plasma sterilization material
Cloth : Absorbing sterilizing agent (used in high temperature and high pressure.);
Paper: Absorbing sterilizing agent (used in high temperature and high pressure.);
Oils : Large molecular density gas is not easy to penetrate;
Moisture : Interference pressure / dilution sterilizing agent;
Powder: Absorbing sterilizing agent (used in high temperature and high pressure.)
Biomonitoring for low temperature plasma sterilization Frequency: At least once a day.
Bacterial species: Bacillus stearothermophilus.
3. Monitoring method:
(1) The first oven is sterilized with the sterilized articles every day.
Placement: The most difficult place for the sterilant to reach the position (behind the shelf of the lower compartment of the sterilization chamber)
Culture temperature: 56~60 degrees Celsius
Control: must be the same batch number as the sterilization group
Observation of results: 24 hours, no more than 72 hours, biological culture must be carried out within 3 hours after the end of sterilization.
4. Item loading principle
The device should be sterilized after packaging and should not be naked.
Be careful not to exceed the scope of the instrument rack when placing the item. Do not touch the door and the bottom of the tank and the plasma electrode net. 3. Pay attention to at least 2.5cm space before the load and plasma electrode mesh, and reserve 8cm space under the hydrogen peroxide tray to ensure the full diffusion of hydrogen peroxide.
Different materials such as metal and plastic are mixed in the sterilization chamber.
Place the sterilization bag on the side and lay it flat, but pay attention to the same side
Items can not be stacked, the instrument box is placed flat on the sterilization rack, and the instrument box is not superimposed.
There is no minimum load limit, but there is a limit on the maximum load, the maximum load should be <80%.
Soft endoscope sterilization (100S/1, NX/1, 100NX/2), can not be sterilized with other instruments, choose long cycle mode, you need to cover the EO cap.
