Clean rooms

It is common knowledge that hospital infections and postoperative complications are a serious problem for healthcare sector. Long-term presence of patients in conventional surgical and therapeutic departments of hospitals can be dangerous for patients. After a short time in the hospital, patients become bacilli carriers, so-called hospital strains and carriers of pathogens of various infections. Any surgical intervention entails the risk of infection of the wound, for each postoperative complication there are people's suffering and huge costs for their treatment.

Particular danger is represented by specific "hospital strains", resistant to antibiotics and not found in everyday life, in particular, methicillin-resistant Staphylococcus aureus, with which nosocomial infections are most often associated. Traditional methods of infection prevention and treatment: antibiotics, immune and hormonal drugs, various serums, wet cleaning of premises with antiseptic solutions, ultraviolet irradiation do not always give the proper effect. The problem of infection of people in medical institutions has arisen with the advent of large hospitals, in which for decades a multitude of people, including carriers of various infections, pass through an alternating stream.

The solution to the above problem is related to cleanroom technology and sterilizing air filtration methods. In clean rooms, depending on their purpose, the concentration of particles with sizes from 0.1 to 5 μm and more in 1 m3 of air does not exceed the established limits. If necessary, the maximum permissible standards for the number of microorganisms are established. Such air purity is provided by a number of special measures, including multi-stage air filtration with the use at the last stage of high-efficiency filters that hold particles with sizes smaller than the minimum size of microorganisms (0.3 μm), ie, providing sterilizing air filtration.

Clean room in comparison with traditional methods of fighting infections and has a fundamental difference. It is not aimed at fighting and destroying already existing microorganisms in the room. It does not allow them to go there, and microorganisms emanating from sick or medical personnel are immediately removed from the room by a stream of air. The high efficiency of this principle was experimentally demonstrated back in 1960 (J. Charnley's research, England) - the use of a sterile operating room with a vertical unidirectional (laminar) air stream having a velocity of 0.3 m / s, which led to a decrease in postoperative sepsis by an order of magnitude.

 reduce the risk of contamination in the area of the operating and tool tables; 

 


 protects a patient from infections and complications;

 

 to ensure the level of microbial contamination within   the limits of the norms stipulated by the relevant international regulatory enactments

 

 the use of modern methods of ventilation and air conditioning removes the problem of staphylococcal infection.
