For example, for patients who have completed reception at the hospital, automatic download (data transmission based on the request from the external confirmation unit 45) is performed at the reception timing, etc., and automatic upload is performed at regular times after the completion of the medical examination on the 1st. You may do so.

The medical record information in the electronic stethoscope 1 may be stored in the storage unit 14 of the sound collection unit 10, but as described above, instead of or in addition to the medical record information, the storage unit 35 of the sound collection unit mounting table 30 may store the medical record information. It may be saved.

Next, the other two examples of the sound collecting unit 10 of the electronic stethoscope 1 will be described with reference to FIGS. 11 (a) and 11 (b).

The sound collecting unit 10 of FIG. 11A has a structure capable of rotating around an axis in the vertical direction and changing the angle of the display screen main body 13a. A plurality of (four in the example) operating convex portions 13b are provided on the peripheral edge of the display screen main body 13a, and the operating convex portions 13b may be rotated and tilted while being hooked by a finger.

The sound collecting portion 10 of FIG. 11B has the same rotation and tilting mechanisms as those of FIG. 11A, but a large number of convex portions 13b for operation are provided on the peripheral edge of the display screen main body 13a. According to this, as in the case of FIG. 11A, it is easy to rotate and tilt, and it also serves as a non-slip, so it is easy to carry.

According to these, the surface of the display screen main body 13a can be oriented in an easy-to-see direction. For example, the orientation of the upper display screen main body 13a can be changed without moving the diaphragm portion 11 from the sound collection target surface during auscultation. Further, even when the sound collecting unit 10 is placed on a desk or the like without being installed on the sound collecting unit mounting table 30, it can be tilted to make it easier to see.
