The important guarantee for the success of the operation is to establish a strict concept of asepsis (i.e. no living bacteria). During the operation, attention should be paid to the operation of asepsis technology to prevent infection. Once infection occurs, it will be irreversible. In the past, many hospitals had to increase the use of antibiotics in order to avoid similar situations. This method is harmful to patients. In recent years, many hospitals are looking for professional operating room purification companies to build their own purification operating rooms. The decoration of ICU can solve the problem of air pollution which has been bothering the hospital for a long time. Therefore, the purification of operating room is paid more and more attention by hospitals.
Advantages and disadvantages of traditional control methods of fungi in non purification operating room purification company
For a long time, cloth disinfection methods, sauces, surgical instruments, enamel and rubber articles have been relatively mature and effective, and the methods used by everyone are usually the same, but the special structure and surrounding environment of the hair to control fungi in the operating room air are different. According to the understanding of operating room purification company, the commonly used disinfection methods for hospital purification operating room are as follows:
1. Lactate fumigation: every 100 cubic meters of room, use 12 ml lactate, add water to evaporate (evaporate), use alcohol to dry to lactate, and close the room for half an hour, then open the window (open the window) for ventilation.
2. UV lamp lighting method: use a certain power of mobile or fixed UV lamp lighting, twice a day, 40 minutes each time. In aseptic operating room, vertical laminar flow is generally used for purification, with good effect. Laminar flow operating room is a kind of "positive pressure" environment, whose air pressure changes according to the cleaning requirements of different areas (such as operating room, sterile preparation room, brush room, anesthesia room, surrounding clean area, etc.).
3. Oxygen disinfection method: install an ozone generator in the operating room and operate it for 30 minutes. In aseptic operating room, vertical laminar flow is generally used for purification, with good effect. Laminar flow operating room is a kind of "positive pressure" environment, whose air pressure changes according to the cleaning requirements of different areas (such as operating room, sterile preparation room, brush room, anesthesia room, surrounding clean area, etc.). Because the operating room of Chengdu operating room decoration company adopts laminar air supply ceiling, the main noise sources are excessive air inlet and unreasonable exhaust design. Fortunately, the volume of the operating room is 42db, without discomfort; the larger noise source is actually equipment and medical equipment, which can avoid reasonable layout and decoration.
The operating room purification company introduced that these disinfection methods have great shortcomings, such as chemical disinfection will produce serious air pollution. The operating room often uses volatile chemical sterilization (fungus) agent (formaldehyde), phenol formaldehyde (phenol) soap of coal, glutaraldehyde, ozone (oxygen), etc. they are irritant substances, which will stimulate the upper respiratory tract, formaldehyde is also sensitive, mutagenesis and carcinogenesis are used, long-term exposure to low dose formaldehyde solution can lead to chronic respiratory system diseases and chromosomal abnormalities. Chemical disinfection results in a large number of chemical drugs remaining in the hospital environment or system, inhibiting the normal flora, producing drug-resistant strains. In a specific environment, there may be a large number of drug-resistant strains breeding, with great potential harm. The health of patients and medical staff constitutes a serious threat.
The biggest disadvantage of several disinfection methods introduced in the decoration of intensive care unit is that it can't effectively control (control) the special structure during the operation: capsule, flagellum and cilia, because the operation safety is the most important part of the key (explanation: metaphorical things) is the environmental control of sterile operating room under dynamic conditions. Therefore, the above air disinfection method is not the best way to solve the problem of indoor air sterility.
