## Abstract

Provided is a biological sound measurement device capable of retaining contact with the body surface in a favorable state and improving a measurement accuracy of a biological sound. A biological sound measurement device (1) includes a sound measurement unit (3) including a sound detector (33) configured to detect a biological sound, and a contact surface (30) configured to be brought into contact with the body surface (S) of a subject, a gripping portion (10) configured to be gripped by a measurer, and a coupling member (40) having a cylindrical tubular shape and elasticity and coupling the gripping portion (10) and the sound measurement unit (3). A wiring (SG) is inserted through a hollow portion of the coupling member (40).

## Claims

### Claim 1

A biological sound measurement device configured to measure a biological sound of a subject, comprising:
a sound measurement unit including a sound detector configured to detect the biological sound, and a contact surface configured to be brought into contact with the body surface of the subject;
a gripping portion configured to be gripped by a measurer; and
a coupling member having elasticity and coupling the gripping portion and the sound measurement unit, wherein
one surface of the coupling member is connected to a surface of the sound measurement unit distanced, in a direction perpendicular to the contact surface, from a surface of the sound measurement unit on which the contact surface is disposed.

### Claim 2 (depends on 1)

The biological sound measurement device according to claim 1, further comprising:
a wiring electrically connecting the sound detector and a substrate built in the gripping portion, wherein
the coupling member has a structure in which the coupling member is spaced apart from the wiring and surrounding the wiring.

### Claim 3 (depends on 2)

The biological sound measurement device according to claim 2, wherein the coupling member is a member having a tubular shape.

### Claim 4 (depends on 2)

The biological sound measurement device according to claim 2, wherein the coupling member includes two tubular members disposed spaced apart in a direction perpendicular to the contact surface, each formed with an opening for passing the wiring, and a plurality of columnar members coupling the two tubular members and arrayed spaced apart from each other around the wiring.

### Claim 5 (depends on 1)

The biological sound measurement device according to claim 1, wherein the coupling member is positioned inward of the sound measurement unit in a state of viewing from a direction perpendicular to the contact surface.

### Claim 6 (depends on 1)

The biological sound measurement device according to claim 1, wherein a deformation amount of the coupling member in response to a force applied in a direction parallel to the contact surface is greater than a deformation amount of the coupling member in response to a force applied in a direction perpendicular to the contact surface.
