Vascular endothelial reactivity measuring apparatus and method for controlling the measuring apparatus
First Claim
1. A vascular endothelial reactivity measuring apparatus comprising:
- a blood flow blocking section for blocking blood flow through the arterial blood vessel of an organism;
an evaluating section for evaluating the geometric property of the arterial blood vessel or its wall; and
a control section for controlling the blood flow blocking section such that the blood flow through the arterial blood vessel is repeatedly blocked and unblocked in at least two iterative blocking/unblocking cycles, wherein during at least a part of a period in which the blood flow through the arterial blood vessel is unblocked, the evaluating section evaluates the geometric property and processes data, representing the geometric property during the partial period, by utilizing the iterative blocking/unblocking cycle.

Abstract
A vascular endothelial reactivity measuring apparatus according to the present invention includes: a blood flow blocking section 2 for blocking blood flow through the arterial blood vessel of an organism; an evaluating section 4 for evaluating the geometric property of the arterial blood vessel or its wall; and a control section 3 for controlling the blood flow blocking section such that the blood flow through the arterial blood vessel is repeatedly blocked and unblocked in at least two iterative blocking/unblocking cycles. During at least a part of a period in which the blood flow through the arterial blood vessel is unblocked, the evaluating section 4 evaluates the geometric property and processes data, representing the geometric property during the partial period, in the iterative blocking/unblocking cycle.
