In the production of sterile pharmaceutical products, reducing or avoiding the risk of microbial contamination, and safely transporting materials (e.g., products, packaging materials, containers, etc.) into sterile production areas are among the most challenging operations. In the field of sterile transfer chamber equipment, the initial sterilization mode is single, and ultraviolet sterilization or vaporized hydrogen peroxide generator sterilization is mostly adopted. Such a transfer chamber has great limitation in practical application, for example, ultraviolet sterilization is difficult to guarantee to the comprehensive sterilization of material after being sheltered from, the time period required by the disinfection of the vaporized hydrogen peroxide generator is relatively long, and the like. In order to solve the problems, an aseptic transfer chamber disclosed in the patent document with Chinese patent number 2013205854822 is designed, and the transfer chamber integrates three modes of ultraviolet sterilization, hydrogen peroxide vaporization sterilization and disinfectant atomization. The atomization mode of the disinfectant in the delivery cabin is that an atomization nozzle is arranged above a cabin body, and the disinfectant enters the atomization nozzle under the action of compressed air to form micro-mist particles and then is sprayed into the cabin body to be disinfected.
