Technical Field
The utility model relates to the technical field of sterilization, in particular to a gas tank detection device.
Background
In hospitals, reusable surgical instruments are used for the next patient after the previous patient is used up and is cleaned, disinfected and sterilized, so that the sterilizer becomes an indispensable device for hospital disinfection supply centers. The sterilizer is divided into two modes of high-temperature sterilization and low-temperature sterilization, wherein the low-temperature sterilization is mainly used for sterilizing objects which are not resistant to humidity and high temperature; the sterilization mode mainly comprises three modes: hydrogen peroxide low temperature plasma sterilization, ethylene oxide sterilization, and formaldehyde sterilization. The ethylene oxide has the best sterilization effect in low-temperature sterilization, and basically does not damage sterilized articles. Furthermore, with the development of minimally invasive surgical techniques, a wide variety of precision surgical instruments will be used in large numbers for clinical use, for which ethylene oxide sterilization is the best option. However, in the daily sterilization operation, the operator often forgets to replace the gas tank or install a new gas tank, and directly starts the program, so that the sterilization fails, and the turnover time of the instruments is delayed. Therefore, it is important to add a gas tank detection mechanism to the apparatus.
