Disclosed is medical equipment for gas monitoring comprising a gas treating system. The system comprises a first gas monitoring module and an integrated gas circuit board (1), wherein the integrated gas circuit board (1) comprises a first gas circuit provided in the interior thereof and a gas outlet (48d), at least one gas inlet and at least one monitoring interface provided on the surface of the integrated gas circuit board (1). The first gas circuit is a pathway the gas inlet comprises a first gas inlet (44d), and the first gas inlet (44d) and the gas outlet (48d) are in communication with the two ends of the first gas circuit respectively. The monitoring interface comprises a first monitoring interface which is used for the first gas circuit to communicate with the first monitoring module, and also comprises an internally installed gas-inlet interface (32c) and an internally installed gas-outlet interface (31c) used so that the first gas circuit can communicate with a second internally installed gas circuit monitoring module. The medical equipment for gas monitoring can effectively reduce connections in the gas circuit via a flexible rubber hose, and it is easy to integrate one gas monitoring module with another gas monitoring module in order to perform at least two forms of gas monitoring on the gas therefore, the structure thereof is simple and compact and the volume of the equipment is reduced.La présente invention concerne un équipement médical destiné à la surveillance du gaz qui comprend un système de traitement du gaz.
