摘要：
Apparatus comprising: a nasal airflow sensing device comprising a first acoustic sensor and a second acoustic sensor configured to be fixed on opposing sides of a nose of an upright patient to acquire first and second acoustic signals respectively for acoustically monitoring airflow through the nose, the first and second acoustic sensors being configured to be fixed on opposing sides of the exterior of the nose so as not to interfere with the airflow through the nose of the patient, wherein the first acoustic signal is indicative of the airflow through the nasal cavity on the side of the nose to which the first acoustic sensor is fixed, the second acoustic signal is indicative of the airflow through the nasal cavity on the side of the nose to which the second acoustic sensor is fixed, and the first and second acoustic sensors pick up their respective acoustic signals from airflow through their respective nasal cavities with little or no cross-talk from the airflow through the other nasal cavity； and a computing system having a data link with the device for receiving and analysing the first and second acoustic signals, wherein the computing system is configured to analyse the first and second acoustic signals in the time domain to derive one or more parameters indicative of a condition of the nasal cavities.Cette invention concerne un appareil comprenant : un dispositif de détection de flux d'air nasal constitué d'un premier capteur acoustique et d'un second capteur acoustique conçus pour être fixés sur les ailes opposées du nez d'un patient en position debout pour acquérir des premier et second signaux acoustiques respectivement et surveiller acoustiquement le flux d'air traversant le nez, lesdits premier et second capteurs acoustiques étant conçus pour être fixés sur les ailes extérieures opposées du nez de façon à ne pas interférer avec le flux d'air traversant le nez du patient, où le premier signal acoustique indique le flux d'air traversant la cavité nasale du
