Abstract
The present invention provides a breathing tube assembly for measuring respiratory gases from a patient. The breathing tube has been optimized for the side-sampling of respiratory gases from steady-state breathing. The breathing tube assembly comprises a breathing tube having three openings, breathing, atmospheric and sample openings. By using breathing and atmospheric openings, a patient can breathe normally to reach to steady state breathing. The sampling tube is coupled with a transport tube, allowing the breathed air traveling through the transport tube. An end of the transport tube away from the breathing tube is connected to a monitor to analyze patient's breathing air.
Claims21
A medical device for sampling breathed air, comprising:
- a breathing tube having a breathing opening and an atmospheric opening;
- a breathing passageway fluidly disposed between the breathing and atmospheric openings;
- and
- a sampling opening physically disposed between the breathing and atmospheric openings, and fluidly coupled with the breathing passageway.
Dependencies are inferred from the claim text.
