Arrangement for passive gas sampling
First Claim
1. An arrangement for passive gas sampling of a breathing gas in a breathing system, comprising:
- a tube-piece having a first connector adapted to receive an inspiratory gas flow, a second connector adapted to deliver an expiratory gas flow, and a third connector adapted to deliver the inspiratory gas flow and to receive the expiratory gas flow;
a measurement chamber associated with said tube-piece; and
said tube-piece further having a first port disposed between said second connector and said third connector and connected to said measurement chamber, a second port disposed between said first connector and said third connector and connected to said measurement chamber and a third port disposed between said first connector and said second connector and connected to said measurement chamber.

Abstract
An arrangement for passive gas sampling of a breathing gas in a breathing system allows sampling during both inspiration and expiration. The arrangement has a tube-piece having a first connector for receiving an inspiratory gas flow, a second connector for delivering an expiratory gas flow and a third connector for delivering the inspiratory gas flow and receiving the expiratory gas flow, a first port arranged between the second connector and the third connector and connected to a measurement chamber, a second port arranged between the first connector and the third connector and connected to the measurement chamber and a third port arranged between the first connector and the second connector and connected to the measurement chamber. The tube-piece is formed such that when an inspiratory flow passes through the tube-piece, a flow is established principally between the first port, the measurement chamber and the second port, and that when an expiratory flow passes through the tube-piece a flow is established principally between the third port, the measurement chamber and the first port.
