Medical Air Purification and Sterilizer Function Introduction

Medical air purification and sterilizers are mainly used in OR room, delivery room, baby room, premature children room, supply room sterile area, burn ward, ICU. The main disinfection principle is as follows:

1.      UV disinfection principle: Radiating microorganisms (bacteria, viruses, spores and other pathogens) with appropriate wavelengths UV, damage and destruction nucleic acids molecular structure in microbial cells to microbial death, so as to achieve the purpose of sterilization

2.      Ozone disinfection and sterilization principle: Ozone use oxidizes’ oxygen atom to destroy the microbial membrane structure to achieve bactericidal action. Ozone is under the unstable molecular structure at room temperature and atmospheric pressure, and soon break into oxygen (O2) and a single oxygen atom (O). A single oxygen atom has a strong activity, strong oxidation for bacteria, to kill them, the excess oxygen atoms will be re-combined into ordinary oxygen atoms (O2), there is no toxic residues.

3.      Photocatalytic disinfection principle: Also known as photocatalyst disinfection, mainly refers to the activation of nano-titanium dioxide photocatalyst through a certain level of light irradiation, resulting in highly oxidizable hydroxyl radicals, through the hydroxyl radical OH locking the air harmful ingredients, decomposition of harmful gases, bacteria and viruses, which effectively degrade toxic and harmful substances in the air and kill micro-organisms.

4.      Plasma sterilization principle: Bipolar plasma electrostatic field was used to decompose and break the negatively charged bacteria, the dust was polarized and adsorbed, and then the second sterilization filter was carried out by means of drug impregnated activated carbon, electrostatic net and photocatalyst catalytic device.

5.      Semiconductor air disinfection machine: Indoor air filter out part of the large particles through the initial filter, from the circulating fan into the semiconductor catalytic positive boss ionization, the bacteria’s cells in the air are ionized oxidation under the action of the boss ionization, loss of vitality and death, and the dust particles in the air was adsorbed on the dust pole by the role of coulons.

Today we will focus on the introduction of UV medical air purification disinfection features:

1.      High efficiency sterilization: UV can reach 99% -99.9% sterilization rate within 1 or 2 seconds for bacteria and virus.

2.      Efficient bactericidal broad spectrum: The broad spectrum of ultraviolet disinfection is the highest, it is almost can kill all of the bacteria, viruses with high efficiency.

3.      No secondary pollution: UV sterilization does not add any chemicals, so it will not produce secondary pollution to the surrounding environment, do not change any component of the air.

4.      Safe and reliable operation: Traditional disinfection techniques such as using chloride or ozone, the disinfectant itself is highly toxic, flammable substances, but UV disinfection system does not have such security risk, and dynamic disinfection can be done for indoor air when someone is in room. (Ozone disinfection must be carried out when nobody in room. Ozone concentration is low, the eye, nose, throat irritation; Concentration 1-15PPm, there will be headache and respiratory local paralysis and other symptoms. Ozone toxicity is related with contact time, generally when contact time is no more than 2 hours on the condition that concentration less than 20PPm, no permanent damage to the human body. If you feel uncomfortable, you can blow out the air, breathe fresh air.)

Those ultraviolet air purification disinfections produced by Shandong Mingtai Medical Equipment Group Co., Ltd have below feature:

1.      Use long-life high-performance non-ozone UV germicidal lamp.

2.      Set disinfection, dust removal, to smell, clean air and other functions in one. 

3.      Release of high concentrations of negative ions, clean air, and promote the body's metabolism.

4.      The special low noise centrifugal fan, big circulating air volume, high efficiency, with high, medium and low three wind speed selection. 

5.      The use of microcomputer automatic control can be realized reservation startup, shutdown function, with fault alarm function, the domestic first 6-24 period timing control, and fully meet hospital needs. Some products are for the high-end Chinese LCD display, beautiful and nice. 

6.      Ultraviolet irradiance real-time dynamic display, real-time dynamic display each lamp’s UV irradiance inside the machine. 

7.      With far infrared remote control, the negative oxygen ions clean air, cumulative time to maintenance alarm automatically, cumulative time to maintain filter alarm, indicating negative ions normal work, ultraviolet germicidal lamp fault alarm automatically, washing indicator lamp function.

8.      Strong activated carbon adsorption of organic gases and odors.
