Problems solved by technology

[0004] However, in the above-mentioned system, for wheezing, only the magnitude between the peak of the frequency spectrum and the reference value (value stored in the memory) is compared, so there is a problem that the detection accuracy of wheezing is not good.

Embodiment Construction

[0058] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0059] figure 1 A block structure of a wheezing detection system (the whole is indicated by reference numeral 1 ) which is an embodiment of the wheezing detection device of the present invention is shown. The wheezing detection system 1 includes a wheezing detector 100 and a smart phone 200 . The wheeze detector 100 and the smartphone 200 can communicate with each other by wireless communication.

[0060] Such as figure 2 As shown in (A), the wheezing detector 100 includes a main body 100M and a first microphone 111 and a second microphone 112 connected to the main body 100M through a microphone plug 113 . In this example, both the first microphone 111 and the second microphone 112 are configured in a stethoscope type having a shape such as a circular disc (the adhesive sheet 119 is provided on its concave surface). It is preset that the first micro...

Abstract

This wheezing detection device is provided with a breathing sound detection unit that detects the breathing sounds of a subject and acquires a chronological breathing sound signal representing the breathing sounds. The wheezing detection device is also provided with a determination processing unit that, for each of preset processing unit periods, converts the breathing sound signal into a frequency space, acquires the frequency spectrum of the breathing sounds, and determines whether a peak (Pd) in the frequency spectrum indicates wheezing on the basis of the height (L) and the width (D) of the peak (Pd).

Description

technical field [0001] The present invention relates to a wheeze detection device, and more specifically, to a wheeze detection device that detects whether wheeze is included in the breath sounds of a subject. Background technique [0002] For example, Patent Document 1 (US 2011 / 0125044 A1) discloses an automated system for monitoring respiratory diseases such as asthma. The system, based on data from microphones and accelerometers, provides a summary of the data and alerts when the severity of symptoms reaches a threshold. Especially for wheezing, measure the peak of the spectrum at a frequency in the range of about 200 to 800 Hz, compare the peak of the spectrum with the predetermined value associated with wheezing stored in the memory, and use the comparison result as a judgment of severity elements. [0003] Patent Document 1: US 2011 / 0125044 A1 [0004] However, in the system described above, wheezing is only compared with the peak of the frequency spectrum and the r...
