Apparatus and method for measuring blood flow

摘要

An apparatus for measuring blood flow includes a detection part and a signal processing part. The detection part includes a blood flow detector for measuring a blood flow of a measured portion of an object, which makes contact with the measured portion, and a force detector for detecting a contact force between the blood flow detector and the measured portion. The signal processing part produces a corrected blood flow in reflection of an error of the blood flow due to the contact force.

1. An apparatus for measuring blood flow, comprising:
a detection part including,
a lower plate,an adiabatic layer on the lower plate,
an upper plate on the adiabatic layer, at least a lower portion of the upper plate being surrounded by the adiabatic layer,a blood flow detector for measuring a blood flow of a measured portion of an object, the blood flow detector being on the upper plate and making contact with the measured portion,a thin film adjacent to the upper plate, the thin film having a stress due to an external force,a supporting member directly on the lower plate, the supporting member supporting the thin film, and the supporting member having a first surface in close proximity to the thin film and a second surface opposite to the first surface, the second surface being farther away than the thin film with respect to the measured portion of the object, anda force detector for detecting a contact force between the blood flow detector and the measured portion, the force detector on the thin film,wherein the blood flow detector is only on the upper plate, the upper plate is thicker than the thin film, and the force detector is only on the thin film; and a signal processing part for
calculating a change in the blood flow due to the contact force, andproducing a corrected blood flow in reflection of the calculated change in the blood flow.
