SPHYGMOMANOMETER
First Claim
1. A sphygmomanometer comprising:
- an operation part that is operated by a part of a patient body;
a pulse wave sensor detecting a pulse wave signal indicative of a pulse wave in the part of the patient body that is operating the operation part;
a first manometer measuring a blood pressure based on the pulse wave signal detected by the pulse wave sensor;
a second manometer measuring the blood pressure with a cuff that is worn by the patient;
a cuff wearing detector detecting a wearing of the cuff by the patient; and
a controller (i) measuring the blood pressure with the first manometer when the operation part is being operated and a duration of the detection of the pulse wave signal by the pulse wave sensor is equal to or greater than a preset time, and (ii) measuring the blood pressure with the second manometer when the operation part is being operated and the cuff wearing detector detects the wearing of the cuff.

Abstract
A sphygmomanometer includes an operation part, a pulse wave sensor that detects a pulse wave signal indicative of a pulse wave in a part of the patient body that is operating the operation part. A first manometer measures a blood pressure based on the pulse wave signal, and a second manometer measures the blood pressure with a cuff that is worn by the patient. A cuff wearing detector detects a wearing of the cuff by the patient. A controller measures the blood pressure with the first manometer when the operation part is operated long enough for a detection of the pulse wave signal and measures the blood pressure with the second manometer when the cuff wearing detector detects that the cuff is worn and that the operation part is being operated.
