Blood pressure monitoring system
First Claim
1. A blood pressure monitoring system for continuously measuring blood pressure of a living body, the system comprising:
- pulse wave detecting means for detecting pulse waves of an arterial vessel of said living body,said pulse wave detecting means comprising a plurality of pressure sensors which are adapted to be set on a body surface of said living body above said arterial vessel, each of said pressure sensors having a dimension smaller than a diameter of said arterial vessel as viewed in a direction perpendicular to said arterial vessel;
pressing means for pressing said pulse wave detecting means against said arterial vessel via said body surface and thereby at least partially flattening said arterial vessel, at least one of said pressure sensors detecting said pulse waves through a flattened wall of said arterial vessel;
blood pressure measuring means for measuring an actual blood pressure of said living body;
control means for determining a relationship between blood pressure and magnitude of pulse waves, based on the pulse waves detected by said at least one pressure sensor through said flattened wall of said arterial vessel and the actual blood pressure measured by said blood pressure measuring means, such that blood pressure is a linear function of magnitude of said pulse waves,said control means determining blood pressures according to the thus-determined relationship based on magnitudes of the pulse waves detected by said at least one pressure sensor through said flattened wall of said arterial vessel; and
display means for displaying the blood pressures determined by said control means.

Abstract
It is desirable to minimize discomfort of a living body due to pressing by a blood pressure monitoring system of a type which monitors the blood pressure of the living body for a long period of time. The present invention is constituted by including pulse wave detecting device for detecting pulse waves of an arterial vessel of a living body, blood pressure measuring device for measuring an actual blood pressure of the living body, and control device for determining a relationship between the pulse waves detected by the pulse wave detecting device and the actual blood pressure measured by the blood pressure measuring device, determining blood pressures according to the thus-determined relationship and based on the pulse waves, and commanding a display to continuously display the thus-determined blood pressures thereon. In accordance with the present invention, blood pressures are determined according to the relationship between the actual blood pressure and the pulse waves, which is determined by the control device, and based on the pulse waves, and the thus determined blood pressures are continuously displayed, thereby eliminating the operation of successively obtaining measurements of the actual blood pressure by using a cuff, for example, and minimizing discomfort felt by the living body.
