Device for measuring a person's ventilation including oxygen-consumption

The present invention relates to a device for measuring a person's ventilation. The device includes a conduit with an exhaled-air receiving portion and an inhaled-air receiving portion. The device includes pressure and oxygen sensor sampling ports. The sampling ports are in fluid communication with the conduit. The device includes a deflector disposed within the conduit. The deflector is configured to deflect air exhaled into the exhaled-air receiving portion of the conduit away from the sensor ports.

Claims preview

1 . A device for measuring a person's oxygen-consumption, the device comprising: a conduit having a first end through which exhalations enter the device along a first longitudinal axis thereof and having a second end through which the exhalations exit the device along a second longitudinal axis thereof angled relative to the first longitudinal axis thereof; a deflector positioned within the conduit and configured to direct the exhalations from the first end towards the second end of the conduit and direct inhalations from the second end to towards the first end of the conduit, the deflector aligning and intersecting with said axes, wherein the deflector is streamlined and configured to inhibit restriction to a flow of exhalations through the conduit, wherein a first flow path of the exhalations from the first end of the conduit through to the deflector is linear, with the first flow path having a proximal end adjacent the first end of the conduit and a distal end adjacent the deflector, wherein a second flow path of the exhalations from the deflector through the conduit to the second end of the conduit is linear, with the second flow path having a proximal end adjacent the deflector and a distal end adjacent the second end of the conduit, and wherein the distal end of the first flow path is near or adjacent the proximal end of the second flow path and wherein the first flow path is connected to the second flow path by a third, curved flow path defined at least in part by a curved surface of the deflector, and wherein the first, second and third flow paths are each shaped to promote a single direction of flow of said exhalations therealong; and an oxygen sensor sampling port positioned within the conduit, the deflector being positioned between the oxygen sensor sampling port and the first end of the conduit. 2 . The device according to claim 1 , wherein the device includes one or more pressure sampling ports in fluid communication with the conduit; and wherein the curved surface of the deflector is configured to deflect the exhalations passing into the first end of the conduit away from the one or more pressure sampling ports, the curved surface of the deflector facing the first end at least in part and facing the second end of the conduit at least in part. 3 . The device as claimed in claim 2 , wherein the deflector is configured to cause said one or more pressure sampling ports to be subject to only a portion of said exhalations passing into the first end of the conduit.
