Liquid separator for removing a liquid from a sample of a breathing gas and airway adapter

An airway adapter comprising:

• a channel surrounded by a wall for a breathing gas flow, said channel being configured to locate between a patient and a ventilator;
• a first port for delivering breathing gas;
• a second port for delivering breathing gas, said second port being in flow communication with said first port through said channel;
• and
• a liquid separator extending into said channel for removing a liquid from a sample of the breathing gas flowing through said channel, said liquid separator comprising a chamber configured to receive the sample of the breathing gas, a membrane having an outer surface exposed to the breathing gas flow, said membrane at least partially surrounding said chamber and which membrane is configured to separate the liquid from the gas sample configured to be received by said chamber, a supporting structure for supporting said membrane, and a connector operationally attached to said supporting structure, said connector comprising a cavity providing a flow path for the sample gas from said chamber through an opening of said cavity to a sample tube, said connector being operationally connected to said wall,
• wherein said membrane is configured to branch from a central part of said channel into at least two different branches, each of said at least two branches extending to different directions towards said wall to obtain the sample.
