Blood flow amount estimating apparatus
First Claim
1. A blood flow amount estimating apparatus, comprising:
- a blood pressure related information obtaining means for obtaining blood pressure related information that is related to a first blood pressure of a first portion of the subject;
a pulse wave detecting device which detects a pulse wave from the first portion;
an arteriosclerosis related information obtaining means for obtaining, based on the pulse wave detected by the pulse wave detecting device, arteriosclerosis related information that is related to arteriosclerosis;
an output device; and
an output-device control means for controlling the output device to output a graph which has an axis indicative of blood pressure related information and an axis indicative of arteriosclerosis related information and indicates that blood flow amount changes with respective changes of blood pressure related information and arteriosclerosis related information, and additionally output, in the graph, a symbol representing the blood pressure related information obtained by the blood pressure related information obtaining means and the arteriosclerosis related information obtained by the arteriosclerosis related information obtaining means.

Abstract
A blood flow amount estimating apparatus 10 which determines a cervical systolic blood pressure CBP(SYS) of a living subject, based on a brachial systolic blood pressure BBP(SYS) and a cervical pulse wave wc of the subject; determines, based on the cervical pulse wave and a heart sound of the subject, a pulse wave propagation velocity PWV as information related to sclerosis or hardness of a carotid artery 46 of the subject; and displays, in a two-dimensional graph 106 which is defined by a first axis 102 indicative of pulse wave propagation velocity PWV and a second axis 104 indicative of cervical systolic blood pressure CBP(SYS) and which indicates that blood flow amount changes with respective changes of cervical systolic blood pressure CBP(SYS) and pulse wave propagation velocity PVV, a symbol 108 representing the actually determined cervical systolic blood pressure CBP(SYS) and the actually determined pulse wave propagation velocity PWV, so that an observer can estimate, from the position of the symbol 108 in the graph 106, an amount of flow of blood in a cervical portion 38 of the subject.
