초록 ▼

This disclosure describes an apparatus and method for measuring analytes in exhaled air. The device contains an inlet through which exhaled air is received. A tube, having a number of different paths running throughout the device, is coupled to the inlet which enables the exhaled air to be re-circulated through the device. At least one portion of the tube is configured in a non-linear fashion. This particular portion of the tube may be used to temporarily store a sample of the exhaled air. The device also contains a converter configured to partially convert an analyte in the exhaled breath from a first state to a second state as the exhaled air is being re-circulated. An analyte sensor is also included to measure the levels of the converted analyte in the exhaled breath.

대표청구항 ▼

1. An apparatus for measuring an analyte in exhaled air, the apparatus comprising: an inlet through which the exhaled air is received;a tube coupled to the inlet, the tube having a plurality of paths and a non-linear portion, the non-linear portion being configured to temporarily store at least a portion of the exhaled air;a pump configured to circulate the exhaled air through the tube;a converter configured to partially convert the analyte from a first state to a second state; andan analyte sensor for measuring the analyte;wherein the at least a portion of the exhaled air is temporarily stored in the tube while it is determined whether the at least a portion of the exhaled air will be passed to the converter or the analyte sensor, and wherein the tube is configured to re-circulate the exhaled air through the converter until a percentage of the analyte converted to the second state exceeds a pre-determined threshold. 2. The apparatus of claim 1, where the non-linear portion is configured as a coil. 3. The apparatus of claim 1, wherein the converter is a catalytic converter. 4. The apparatus of claim 1, further comprising one or more valves coupled to the tube, wherein the one or more valves are configured to change a flow path of the exhaled air through the tube from a first path of the plurality of paths to a second path of the plurality of paths. 5. The apparatus of claim 1, wherein the converter is configured to receive the partially converted air at least a second time and perform at least a second partial conversion of the analyte from the first state to the second state. 6. The apparatus of claim 1, wherein the analyte is nitric oxide and the converter is configured to partially convert the nitric oxide to nitrogen dioxide. 7. The apparatus of claim 6, wherein the analyte sensor is configured to measure nitrogen dioxide. 8. An apparatus for measuring an analyte in exhaled air, the apparatus comprising: an inlet through which exhaled air is received;a tube coupled to the inlet, wherein at least a portion of the tube is configured to store a sample of the exhaled air, the portion of the tube being in a non-linear configuration;a pump configured to circulate the exhaled air through the tube; anda converter configured to receive the exhaled air at least a first time and a second time, wherein when the exhaled air is received the first time, the converter partially converts the analyte from a first state to a second state and wherein when the analyte is received the second time, the converter further converts the analyte from the first state to the second state, and wherein the sample of the exhaled air is temporarily stored in the tube while it is determined whether the sample of the exhaled air will be passed to the converter, and wherein the tube is configured to re-circulate the exhaled air through the converter until a percentage of the analyte converted to the second state exceeds a pre-determined threshold. 9. An apparatus for measuring an analyte in exhaled breath, the apparatus comprising: an inlet through which exhaled air is received;a tube coupled to the inlet, the tube having a non-linear portion configured to store the exhaled air;a converter configured to partially convert the analyte from a first state to a second state; andan analyte sensor for measuring the analyte in the exhaled air, wherein the exhaled air is temporarily stored in the tube while it is determined whether the exhaled air will be passed to the analyte sensor,wherein the tube is configured to re-circulate the exhaled air through the converter until a percentage of the analyte converted to the second state exceeds a pre-determined threshold. 10. The apparatus of claim 9, wherein the converter is a catalytic converter. 11. The apparatus of claim 9, wherein converter partially converts the analyte from nitric oxide to nitrogen dioxide. 12. The apparatus of claim 9, wherein the analyte sensor is configured to measure nitrogen dioxide. 13. The apparatus of claim 9, wherein the non-linear portion is configured as a coil.
