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

摘要

A liquid separator removing a liquid from a sample of a breathing gas flowing through an airway adapter having a channel surrounded by a wall is disclosed herein. The separator includes a chamber receiving the sample, and a membrane having an outer surface exposed to the gas flow, the membrane at least partially surrounding the chamber, which membrane separates the liquid received by the chamber. The separator also includes a supporting structure for supporting the membrane, and a connector operationally attached to the supporting structure, the connector being connectable to the adapter. The connector comprises a cavity providing a flow path for the sample from the chamber through an opening of the cavity to a sample tube. The membrane branches from a central part of the channel into at least two different branches extending to different directions.

1. A liquid separator for removing a liquid from a sample of a breathing gas flowing through an airway adapter having a channel surrounded by a wall, said channel being configured to locate between a patient and a ventilator, said liquid separator comprising:
a chamber configured to receive the gas sample of the breathing gas; a membrane having an outer surface exposed to the breathing gas flow, said membrane at least partially surrounding the interior of said chamber and said membrane is configured to separate the liquid from the gas sample received by said chamber; a supporting structure for supporting said membrane; and a connector operationally attached to said supporting structure and which connector is connectable to said airway adapter, 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, 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 to obtain the sample, and wherein said opening is positioned in said central part of said channel.
