Sphygmomanometer system
First Claim
1. A sphygmomanometer system for measuring blood pressure of a predetermined part of a subject, the sphygmomanometer system comprising:
- a first device configured to be pressed against the predetermined part of the subject by a force of a finger of a measurer and to generate a plurality of voltage signals in measurement of the blood pressure; and
a second device configured to measure the blood pressure according to the plurality of voltage signals from the first device,wherein the first device includes;
a holder;
a transmission coil fixed relative to the holder and configured to generate a magnetic field;
a first detector configured to be pressed against the predetermined part and to move relative to the transmission coil;
a first spring which connects the first detector to the holder and configured to repel the first detector;
a first reception coil disposed on the first detector;
a second detector supported by the first detector and configured to be pressed against the predetermined part and to move relative to the transmission coil;
a second spring which connects the first detector and the second detector and is configured to repel the second detector, the second spring having a spring constant smaller than that of the first spring; and
a second reception coil disposed on the second detector,wherein the first device is configured to output a first voltage signal corresponding to movement between the transmission coil and the first reception coil on the first detector and output a second voltage signal corresponding to movement between the transmission coil and the second reception coil on the second detector, andwherein the second device includes;
a display; and
a processor configured to;
calculate an average blood pressure based on the first voltage signal and calculate a highest blood pressure and a lowest blood pressure based on the second voltage signal and the average blood pressure; and
display the average blood pressure, the highest blood pressure and the lowest blood pressure.

Abstract
The present invention provides a sphygmomanometer system, including a measurement device pressed against a predetermined part to be measured so that the part to be measured is held down, and a blood pressure measurement device to measure blood pressure based on information from the measurement device. The measurement device includes an average blood pressure detection unit to obtain information on pressure applied to the measurement device, and a blood pressure change amount detection unit to detect a minute change of the part to be measured when the blood pressure change amount detection unit contacts with the part to be measured. The processor of the blood pressure measurement device calculates the average blood pressure, the highest blood pressure, and the lowest blood pressure based on information on pressure obtained from the blood pressure change amount detection unit and the average blood pressure detection unit.
