The invention discloses an intelligent nasopharyngeal
catheter and a
breath sound monitoring system.The intelligent nasopharyngeal
catheter comprises a nasopharyngeal
catheter body, a first acoustic sensing part and an
optical fiber, the nasopharyngeal catheter body comprises a first body and a second body, and the first body is connected with the second body; the cross sectional area of the second body is gradually increased from one end, close to the first body, of the second body to one end far away from the first body; at least part of the
optical fiber is embedded in the first body, the first acoustic sensing part is arranged on the
optical fiber and located in the first body, the first acoustic sensing part is used for converting vibration and / or pressure fluctuation of
breathing sound
waves of a patient into optical signals, and the optical
fiber is used for being connected with a
demodulation host so that the
demodulation host can receive the optical signals from the first acoustic sensing part. Therefore, the
breathing signal can be collected through the first acoustic sensing part, and the
breathing signal of the patient can be transmitted to the
demodulation host, so that the breathing condition of the patient can be monitored in real time to guarantee the safety of the patient.
