subject: Yourself doctor for high blood pressure people [print this page] The blood pressure monitor manufacturers system as set forth in claim 1, wherein said blood pressure variation determining means selects, from the pulses of the pulse wave detected by said pulse wave detecting means during a predetermined time duration after said relationship is updated by said relationship determining means, pulse having a greatest maximum magnitude of maximum magnitudes of said pulses and a pulse having a smallest maximum magnitude of said maximum magnitudes, and determines, as said variation of the blood pressure monitor manufacturers of said subject, an absolute value of a difference between said greatest and smallest maximum magnitudes.
There is known a blood pressure monitor manufacturers apparatus of the type which includes (a) a pulse wave detecting device detecting a pulse wave produced from an artery of a living subject, (b) a blood pressure measuring device measuring a blood pressure of the subject by pressing the subject's body portion with a pressing device, (c) a relationship determining means determining a relationship between blood pressure and pulse wave magnitude, based on a pulse wave magnitude detected by the pulse wave detecting device and a blood pressure monitor manufacturers value measured by the blood pressure measuring device, and (d) a blood pressure monitor means continuously determining, according to the determined relationship, blood pressure values of the subject based on magnitudes of the pulse wave detected by the pulse wave detecting device, and in which apparatus the relationship determining means updates the relationship at predetermined regular intervals of time, based on blood pressure values measured by the blood pressure measuring device. An example of the monitor system is disclosed in a Japanese Patent Application filed by the Assignee of the present application, which was laid open under Publication No. 1(1989)161707. The monitor system is used for, for example, monitoring the blood pressure monitor manufacturers of a patient after, or during, a surgical operation.
It is therefore an object of the present invention to provide a blood pressure monitor manufacturers system which continuously determines blood pressure values of a living subject, according to a relationship between blood pressure and pulse wave magnitude, based on actually detected magnitudes of a pulse wave, and updates the relationship at intervals of time based on blood pressure values actually measured using a pressing device, which system reduces patient's discomfort due to the unnecessarily frequent pressing with the pressing device when the patient's blood pressure monitor manufacturers do not vary so largely and provides accurate blood pressure monitoring when the blood pressure varies largely.
