摘要

Apparatus for detecting at least the presence of halogenated agents, method of monitoring of air exhaled by a patient, and apparatus for filtering exhaled air with halogenated agents. The invention relates to a detector that monitors the presence of halogenated agents and the presence of N20 and includes a base to which a tin of filter is removivelmente attached.The canister has an input for accepting exalante of a patient or a machine of anaesthesia and a way to send the exalante filtrate as gases to the base. The filtered gases are sent to a measuring cell and monitoring of gas housed in the base. The cell has a system of sensing halogenated agents and a system for sensing N ~ 2 ~ o.When the filter material in the filter canister can no longer filter the halogenated agents, the agents are passed from the filter to the measuring cell, which will detect the presence of halogenated agents. An audible alarm sounds when the halogenated agents are detected. This shows that the user is in time to replace the filter canister.If n ~ 2 ~ is used, its presence is detected by the sensor of N ~ 2 ~ in the measuring cell. If n ~ 2 ~ is detected, an audible alarm sounds to inform the user that N ~ 2 ~ is present and that the user must carry out the appropriate preventative steps.
