[0041] Configuration of respiratory condition display system

[0042] figure 1 is a diagram illustrating an example configuration of a respiratory condition display system according to the first embodiment of the present invention. The respiratory condition display system includes a breathing sound measuring device 10 , a noise reducer 20 , a respiratory condition analyzing device 30 and a display device 40 .

[0043] The breath sound measurement device 10 is configured to measure a time-series sound signal including the breath sound of a living body such as a human. The breath sound measurement device 10 may be implemented eg as a stethoscope, or any other tool such as a microphone located near the throat or a pressure or acceleration sensor contacting the skin of the throat or chest may be used to measure time-series breathing signals. A preferred example of the breath sound measurement device 10 will be described below.

[0044] The noise reducer 20 is configured to perf...

Abstract

The invention provides a respiratory signal processing apparatus, a respiratory signal processing method, and a program. A respiratory signal processing apparatus includes a pulse-based component detection unit configured to detect a pulse-based component from a first signal acquired from a living being, and a pulse-based component removal unit configured to remove the detected pulse-based component from a second signal acquired from the living being, the second signal including respiratory sounds.

Description

technical field [0001] The invention relates to a respiratory signal processing device. More specifically, the present invention relates to a breathing signal processing device and a breathing signal processing method for removing specific signals from time-series breathing signals including breathing sounds of living organisms such as humans, and a program enabling a computer to execute the method. Background technique [0002] It has been established that breathing sounds are picked up using a stethoscope or the like to check biological conditions. Continuous monitoring of breathing sounds is also useful in medical settings. However, since noise other than the breathing sound often exists when monitoring the breathing sound, it is necessary to properly remove such noise. The noise may include internal sounds of the subject or patient such as heart sound and external environmental sounds such as voices, music, and operating sounds or alarm sounds from other medical instru...
