Biological Monitoring Device
First Claim
1. A living body monitoring device, comprising:
- a monitoring unit configured to monitor a temporal change in depth of one or a plurality of feature points in a living body based on a signal received from an ultrasonic sensor;
a respiration identifying unit for identifying expiration or inspiration based on information regarding the depth of the feature point; and
a lung sound analysis unit configured to identify both or either a lung sound at the time of expiration and a lung sound at the time of inspiration based on lung sound data received from a lung sound sensor and information regarding expiration or inspiration identified by the respiration identifying unit.

Abstract
To identify exhalation and inhalation of a subject more accurately. A biological monitoring device (1) comprises: a monitoring unit (12) which monitors changes over time in the depth of feature points at one or a plurality of locations within a living body, on the basis of a received signal received from an ultrasonic sensor (2); and an exhalation/inhalation identifying unit (13) which identifies exhalation or inhalation on the basis of information relating to the depth of the feature points. Contraction and expansion of the lungs, in other words exhalation and inhalation, can be identified by applying ultrasound waves from between the ribs of a subject to monitor movements of biological tissue which moves together with the lungs.

8. A living body monitoring device, comprising:
-
a monitoring unit configured to monitor a temporal change in depth of one or a plurality of feature points in a living body based on a signal received from an ultrasonic sensor; a respiration identifying unit for identifying the timing of apnea based on information regarding the depth of the feature point; and a heart sound analysis unit configured to extract heart sounds during an apnea identified by the respiration identifying unit from heart sound data received from a heart sound sensor.
