subject: How To Pick Up The Best Blood Pressure Monitor [print this page] Generally, a blood pressure monitor manufacturers apparatus which monitors blood pressure values of a living subject for a considerably long time includes a cuff being worn on a portion of the subject and a blood pressure measuring device for measuring a blood pressure value of the subject by changing a pressure of the cuff. The blood pressure value measured by the blood pressure measuring device using the cuff enjoys high reliability. As one type of the above-mentioned blood pressure monitor apparatus, there is known an apparatus which starts a blood pressure measurement of a blood pressure measuring device and outputs the measured blood pressure values of a living subject at a predetermined period.
However, in the above blood pressure monitor manufacturers, if the interval between successive blood pressure measurements is shortened for improving the accuracy of blood pressure monitoring, the frequency of pressing of the cuff is increased and the subject feels more discomfort. In the case where the frequency of pressing of the cuff is excessively high, congestion occurs to the body portion on which the cuff is worn, and accurate blood pressure values are not obtained.
Further, there has been proposed a monitor blood pressure monitor manufacturers apparatus including a blood pressure measuring device for measuring a blood pressure value of a living subject based on variation of a pulse-synchronous wave obtained by changing a pressure of a cuff being worn on the living subject, a pressure pulse wave sensor adapted to be pressed on an artery of the subject for detecting a pressure pulse wave produced from the artery of the subject, a pressure pulse wave- blood pressure relationship determining means for determining, at a predetermined period, a pressure pulse wave- blood pressure relationship between magnitude of pressure pulse wave and blood pressure based on the pressure pulse wave detected by the pulse wave sensor and the blood pressure measured by the blood pressure measuring device, by starting the blood pressure measuring device at the predetermined period, and a monitor blood pressure determining means for successively determining a monitor blood pressure value based on an actual pressure pulse wave detected by the pressure pulse wave sensor, according to the pressure pulse wave- blood pressure relationship. An example of the blood pressure monitor apparatus is disclosed in Laid-Open publication No. 5-3858 of Unexamined Japanese patent application. The blood pressure monitor apparatus is capable of detetermining a monitor blood pressure value for each heartbeat-synchronous pulse of a pulse wave.
