Blood pressure measurement device with sound detection function and blood pressure measurement method
View Patent ↗A blood pressure measurement device measures a blood pressure of a subject by a blood pressure measurement unit, detects a body sound of the subject during blood pressure measurement by a sound detection unit. The measured blood pressure and the detected body sound are recorded in association with each other by time information. The factor for the increase of measured blood pressure value can be specified by showing the chronological blood pressure measurement result along with checking the presence or absence of a body sound such as snoring etc.
1. A blood pressure measurement device with a sound detection function, the blood pressure measuring device comprising:
a blood pressure measurement unit configured to measure a blood pressure of a subject;
a sound detection unit configured to detect a body sound of the subject during blood pressure measurement by the blood pressure measurement unit; and
processing circuitry coupled to a memory, the processing circuitry configured to record the blood pressure measured by the blood pressure measurement unit and the body sound detected by the sound detection unit in association with each other by time information, wherein
the sound detection unit includes a microphone configured to detect sounds,
the body sound includes at least one of snoring, coughing, sneezing, hiccups, sleep talking or teeth grinding from a mouth of the subject, the body sound affecting a blood pressure value to be measured, and
the blood pressure measurement unit is configured to determine a start time for recording the body sound by the microphone using a timing of blood pressure measurement so as to start recording the body sound by the microphone before a start of each of a plurality of blood pressure measurements when measuring the blood pressure in a blood pressure measurement mode.
2. The blood pressure measurement device with a sound detection function according to claim 1 , wherein
the blood pressure measurement unit includes a cuff configured to be attached to the subject, and
the microphone is configured to be rotatably attached to the cuff via a rotation adjustment mechanism.
3. The blood pressure measurement device with a sound detection function according to claim 1 , further comprising:
a cuff integral with the blood pressure measurement device,
wherein the microphone is provided on the blood pressure measurement device or the cuff so as to be directed to the mouth of the subject when the blood pressure measurement device is attached to an upper arm of the subject.
4. A blood pressure measurement method using a sound detection function, the blood pressure measurement method comprising:
measuring a blood pressure of a subject;
detecting a body sound of the subject, the body sound including at least one of snoring, coughing, sneezing, hiccups, sleep talking or teeth grinding from a mouth of the subject, and affecting a blood pressure value to be measured, the detecting of the body sound being started before a start of the measuring of the blood pressure;
recording the body sound detected in the detecting of the body sound and the blood pressure measured in the measuring of the blood pressure in association with each other by time information; and
determining a start time for the recording of the body sound using a timing of blood pressure measurement so as to start the recording of the body sound before a start of each of a plurality of blood pressure measurements when performing the measuring of the blood pressure in a blood pressure measurement mode.
