Discussion on the Importance of ICU Ward Air Purification in the Control of Hospital Influencing

Latest company news about Discussion on the Importance of ICU Ward Air Purification in the Control of Hospital Influencing

The construction of the central ICU is a comprehensive symbol of modern hospitals and a reflection of the hospital level. It builds an emergency channel for critical patients between the emergency department and each department and concentrates high-risk patients for observation and treatment. It can improve the utilization rate of advanced equipment in the hospital and facilities management and nursing. However, ICU may bring negative effects of cross-infection.


ICU is the top priority of hospital sense control:
1、 The patients in the central ICU are all high-risk and susceptible patients, with a weak constitution, poor immune ability, and easy to be infected;

2、 Patients in central ICU suffer from different pathogens, different parts, and different degrees of infection. After the infection is concentrated, they may become the source of cross-infection;

3、 Patients in the central ICU come from different departments. They may bring pathogenic microorganisms from other departments into the center. When they are transferred out of the ICU, they will bring pathogens into the general ward;

4、 Patients may have used a variety of antibiotics for a long time, and most of them are the latest and most lethal antibiotics. The possibility of double infection caused by drug-resistant strains is high;

5、 The monitoring and treatment instruments used in the central ICU are easy to cause infection;

6、 There are pathogenic microorganisms in the air and surface of the central ICU ward;

7、 The flow of personnel in the central ICU is large, which is easy to cause dust lift, so that the bacteria in the dust return to the air;

8、 Many valuable precision instruments are used in the central ICU. The dust particles and harmful gases in the air will damage the instrument and reduce its service life.
The ICU in the center has a large number of personnel and a large flow, so there are many dust sources and a large amount of dust. The pollution concentration it may produce is much higher than that in the operating room, and it is continuous for 24 hours. Therefore, the air disinfection and cleaning measures in the ICU should have higher requirements than those in the operating room.

When choosing the continuous air disinfection and cleaning equipment, the number of air changes is an important index. In the operating room or other class II environment of the hospital, the air exchange frequency of 8-15 times per hour can meet the disinfection and health standards of the hospital, but not for the central ICU. According to the actual situation of the ICU, through the inspection and scientific measurement of who, the air change frequency of 20 times per hour is necessary for the ICU.


Ekeair MKJ mobile sterilization station

The MKJ mobile sterilization station of Ekeair, developed by Professor Wu Jixiang of Shanghai Jiaotong University, breaks the traditional disinfection mode of unmanned occasions, is easy to operate, realizes dynamic continuous disinfection in the presence of people, and has no secondary pollutants such as ozone and nitrogen oxides. Ekeair MKJ mobile sterilization station carried out the air mist test in the environment cabin, and the removal rate of staphylococcus albus was more than 99.99% in 20 minutes; after 20 minutes of working in the indoor space, the removal rate of natural bacteria was more than 90%; the total number of bacteria was less than 10 CFU / m3. The product has the characteristics of nonbuilding laminar flow, which is different from the traditional building filter laminar flow. The air change frequency can reach up to 40 times / h, which can meet the requirements of cleaning and hygiene, and the central ICU dry clean air.
