The transfer window is a kind of general purification equipment in the clean room. It is installed on the wall of the clean room and used for the transfer of items between clean rooms and between clean rooms and non-clean rooms. The transfer window can reduce the number of door openings of the clean room and reduce the pollution degree of the clean room.
The transfer window is widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCDs, electronics factories, etc., where air purification is required.
What is the difference between the medical transfer window and the negative pressure ward transfer window?
Transfer windows can be classified according to different use environments. Medical transfer windows are a type of transfer windows, which are mainly used in hospital operating rooms, negative pressure wards, ICUs and other environments with high air quality requirements. The transfer window used in the negative pressure ward is a special case of the medical transfer window.
The requirements for the transfer window of the negative pressure ward and the negative pressure isolation ward are relatively special, mainly because of the problem of the use environment. The negative pressure isolation ward is mainly used to admit patients with infectious diseases such as the respiratory tract, such as patients with SARS and new coronary pneumonia. Because the air and articles used by these patients are dangerous, they need to be treated specially. First, the air in the patient's room needs to be filtered and disinfected before being discharged through a safe way. Secondly, the items contacted by patients need to be recycled or discarded through special methods after sterilization. In this process, we need to use what we call transfer windows. The function of the transfer windows here is to reduce the opening of the ward and reduce the contact area of personnel. Therefore, the transfer window has a considerable effect on the negative pressure isolation ward.
The transfer window configured in the negative pressure isolation ward is generally made of stainless steel, which has a certain strength and firmness, and has a smooth surface, which is not easy to generate dust. More importantly, stainless steel has a certain degree of cleaning agents and disinfectants used in hospitals. There is no risk of rust, and will not affect the robustness and sealing of the transfer window. This material selection prolongs the service life of the transfer window, reduces the difficulty of cleaning, and also takes into account the aesthetics. It needs to be specifically pointed out that the transfer window of the negative pressure ward must be equipped with ultraviolet sterilization function. It can sterilize the delivered items. There are also some small details in the internal structure of the transfer window that can be improved. For example, the interior is designed with a rounded corner, which is convenient for cleaning and beautiful.
