Description

Toxic gas emission monitoring alarm device of ethylene oxide sterilizer Technical Field The utility model relates to the field of ethylene oxide sterilizers, in particular to a toxic gas emission monitoring and alarming device of an ethylene oxide sterilizer. Background The ethylene oxide sterilizing device is a key device of a disposable sterile medical instrument production enterprise, has special requirements for installation operation and use management, uses ethylene oxide as a sterilizing agent, is a broad-spectrum sterilizing agent, and can kill various microorganisms including spores, tubercle bacillus, bacteria, viruses, fungi and the like at normal temperature. The patent document with the bulletin number of CN209900166U provides a toxic gas emission monitoring alarm device of an ethylene oxide sterilizer, which comprises a sterilizer body, wherein a gas emission pipe is arranged outside the sterilizer body, one end of the gas emission pipe, which is far away from the sterilizer body, is provided with an ethylene oxide detection device, the gas emission pipe comprises a left emission short pipe and a right emission short pipe, the right emission short pipe is connected with the left emission short pipe through a control valve, a main board is arranged in the sterilizer body and is connected with the ethylene oxide detection device, the main board is connected with a display, the display is arranged on the side wall of the sterilizer body, and the main board is connected with the alarm.
