Gas flow system, adaptor, and method

摘要

An airway adaptor that measures the concentration of at least one of a specific component and the flow rate of a supply gas and a return gas. The airway adapter may include a tube having a flow path in which the supply gas and the return gas passes. The tube may include a first end having a first aperture for guiding the supply gas into the flow path, and second end having a second aperture for guiding the return gas. Further, the airway adapter may include a measurement device operable to measure at least one of the supply gas and the return gas in the air flow path and a partial shielding disposed at the first aperture and structured to shield a portion of the air flow path. The supply gas may be a respiratory gas and the return gas may be inhaled or exhaled breath of a person.

主权项

1. An airway adaptor operable to measure a concentration of at least one of a specific component and a flow rate of a supply gas and a return gas, the airway adapter comprising:
a tube having a flow path in which the supply gas and the return gas passes, the tube including only a single partial shielding, a first end having a first aperture for guiding the supply gas into the flow path, and a second end having a second aperture for guiding the return gas; and a measurement device operable to measure at least one of the supply gas and the return gas in the air flow path, wherein the partial shielding is located only at an outermost end of the first end of the adapter, and structured to shield a portion of the air flow path, the partial shielding including two elongate structures that extend across an entire width of the flow path and intersect each other in the flow path.
