1. INTRODUCTIONS OF THE PRODUCTS 1) Bed Sterilizer THEME BASIS

Keeping the hospital environment infection free is a prime concern of any conscientious hospital management. Preventing contamination and spread of infection is an assigned responsibility of the doctors and nurses, which can never be compromised. The most common cause of high internal rate of infection in a hospital is the poor sanitization of the beddings (sheets, pillows, mattresses etc) and the clothing used by the patients. Till now, the most commonly used methods of sanitizing bed sheets ， mattresses ， pillows ， etc. have been ultra-violet radiation and utilization of highly compressed steam. These methods can, at best, disinfect the surfaces but have not been so effective in eradicating the deep rooted pathogens. Guangzhou Kangzhen Medical Equipment Co. Ltd., following many years of extensive research, has developed KZ-X-DLI model of fully computer controlled Bed Sterilizer. This Bed Sterilizer can be an excellent facility for cross-infection control and sanitization. It can root-out infection most economically and effectively prevent the spread of diseases in a hospital environment. The Bed sterilizer is the latest equipment of its kind and has been listed in the Disinfection Technical Standards published by the Department of Health in 2002. This Ozone Bed Sterilizer is now the only assigned method of sterilization.

INDICATION

The ozone sterilizing equipment can be applied to the bedding streilization in hospitals and hotels, which includes the sterilization of mattresses; bed clothes, carpet, pillow fillers and bed sheets and so on. In addition, it can also be applied for air sterilization in office; laboratory, meeting room, etc.

DIRECTION

1. Put the mattresses, bed clothes, bed sheets, pillows, etc. into the sealed plastic sterilization bags and then connect the gas transport pipes. 2. Turn on the power button ON. Then choose the sterilizating time, from 20 to 30 minutes. Last, press the thin film switch ON, and then the equipment would begin to work. Count down the time, and when the clock reaches 00, the disinfecting operation has finished. 3. After finishing the sterilizing operation, the equipment would ring. After that, take off the gas transport pipes, and insert the plug of the sterilization cover, and keep the ozone in the sterilization cover for around 30 minutes.

MAJOR TECHNOLOGY CRITERIA Comparing with other internal and external similar advanced technology KangZhen product technology Other products technology Ozone Bed Sterilizer Ozone Sterilizer 1. With vacuum sterilization function, the ozone Without vacuum sterilization function, ozone disinfector can sterilize beddings thoroughly and can not penetrate through the beddings, which effectively. can only sterilize the surface. 2. The Bed Sterilizer has adopted the most Adopted the general porcelain mode of ozone advanced technology of BNP titanium-ceramic generator, short working life, and must be structured ozone generator, and the lowest ozone replaced after working for ５ 000 hours. The output can reach 7g/h, whose working life is as 3 lowest ozone output is about 3g/h, and its times as the other average ozone generators. working life is about 3 years 3. Fully sealed model which prevent any ozone Only adopt the piece mode disinfecting bed leakage from the equipment can ensure the safety cover to sterilize beddings, which is only semi- of both patients and hospital staff. sealed. So there will be ozone leakage from the bed, which will influence the patients and staff around. 4. The additional ozone degradation function, No such function. which has been granted structure patent can decompose the ozone remained, which can prevent the pollution of environment. 5. It can apply to the clothing sterilization of staff Only sterilize the surface of beddings. in hospital other than bedding disinfection. 6. It is unique in China that can disinfect 3 beds at Only can disinfect 2 beds at the same time. the same time, which has increase the efficiency of bedding disinfection, and solve out the problem of bed shortage in hospital obviously. 7. The interior of the sterilizer has a huge Adopt the copper electromagnetic valve powerful stainless steel electromagnetic valve interior only, which can be easily etched by the which mean reduced equipment downtime. ozone, and must be replaced after one year. 8. It is unique in China that has total digital The whole sterilization process just includes command and automatic function. The whole two steps: ozone generating & maintain, which operation process is just to press one key, and can only disinfect the surfaces. Moreover, there then it would enter four sterilization steps: will be ozone leakage during the sterilizing vacuum disposal-ozone generating-remain-ozone process, which will etch the oxygen pipes in decomposition. the ward, and influence the patients and staff around.

3. OZONE DISFINFECTION MECHANISM

The Sterilization function of ozone belongs to a biochemistry oxidization reaction. Because of its high oxidation potential, ozone oxidizes cell components of the bacterial cell wall. This is a consequence of cell wall penetration. Once ozone has entered the cell, it oxidizes all essential components (enzymes, proteins, DNA, RNA). When the cell membrane is damaged during this process, the cell will fall apart. This is called lysis, see figure 1 below. The above-mentioned mechanism differs from that of halogens (such as chlorine), which are usually applied. Chlorine is known to penetrate cells by diffusion. Within the cell, chlorine affects several enzyme types.

Figure 1: Bacterial lysis by ozone in 6 steps (see below)

Ozone Sterilization steps: 1 – Computer animation of a bacterial cell 2 – Close-up of an ozone molecule on the bacterial cell wall 3 – Ozone penetrates the cell wall and causes corrosion 4 – Close-up of the effect of ozone on the cell wall 5 – Bacterial cell after it has come in contact with a number of ozone molecules 6 – Cell destruction (lysis)

4. SAFETY OF OZONE DISINFECTION

Ozone is a safe gas that treats the environment friendly. And its only toxicity is from its high oxidation potential. When the ozone concentration reaches 1.55ppm or up, people should not be allowed to stay around, because ozone is injurious to the breathing system of human body when it’s serious. Therefore, the ozone industrial associations have set health standard as follows:

International Ozone Association: 0.11ppm—approach—10 hours

United States of America: 0.1ppm—approach—8 hours Germany/France/Japan, etc: 0.1ppm—approach—10 hours China: 0.15ppm—approach—8 hours

Above are standards for keeping people in an ozone environment safely. Ozone concentration multiplied by its approach time can be seen as its standard point. As it’s reported that when ozone concentration reaches to 0.02ppm, people with sensitive smell can perceive it, which is called felling edge point; when the ozone concentration reaches to 0.15ppm, it’s called smell edge point, at which the ozone can be smelt by average people, and it is also known as the healthy standard point; in addition, when the ozone concentration reaches 1-10ppm, it is called the stimulation scope; when the concentration is above 10ppm, it is the point of poisonous edge. In fact, applying ozone appropriately can prevent people from suffering. Instead, it is good for human when the ozone concentration is less than 0.1ppm in an environment. Ozone has been applied for more than 100 years. So far, there’s no one case reported that somebody was poisoned by ozone.
