| 摘要 |
A breath analysing and training assembly adapted to detect the carbon dioxide(CO2) concentration in the breathing gas of a user, the assembly comprises a selective colorimetric CO2 detector provided with a detector surface adapted to change color rapidly and reversibly with the concentration of CO2,when exposed to CO2, and an adapter comprising -a docking part for receiving a mobile unit comprising an image capturing means, a display, and a processing means,wherein the docking part is configured to position said image capturing means in a fixed relation to said colorimetric detector, such that said image capturing means is adapted to capture images of said detector surface, -a detector holding part adapted to receive said colorimetric detector,wherein said adaptor includes a detector surface protecting means adapted to protect the surface from ambient air in an airtight fashion when no measurement is performed, -a breathing conduit to lead breathing gas to and from said user such that at least a part of the breathing gas passes the detector surface, wherein said processing means is adapted to execute an application program adapted to perform a measurement session including a measurement step for measuring CO2 concentration changes in breathing gas by identifying color changes of images of said detector surface captured by said image capturing means. |
