Blood pressure monitoring apparatus
First Claim
1. A blood pressure monitoring apparatus comprising:
- blood pressure measuring means for measuring a blood pressure employing a cuff;
pulse wave propagation parameter measuring means for measuring a pulse wave propagation parameter;
hemodynamics measuring means for measuring hemodynamics, and control means for controlling said blood pressure measuring means based on a change in the pulse wave propagation parameter measured by said pulse wave propagation parameter measuring means and a change in the hemodynamics measured by said hemodynamics measuring means, wherein said control means controls said blood pressure measuring means to measure the blood pressure based on the amount of change and a change in trend in the pulse wave propagation parameter measured by said pulse wave propagation parameter measuring means, and the amount of change and a change in trend in the hemodynamics measured by said hemodynamics measuring means.

Abstract
A blood pressure monitoring apparatus includes a blood pressure measuring device for measuring blood pressure employing a cuff, a pulse wave propagation time measuring device for measuring the pulse wave propagation time, a hemodynamics measuring device for measuring the hemodynamics, and a control device for controlling the blood pressure measuring device on the basis of a change in pulse wave propagation time measured by the pulse wave propagation time measuring device and a change in hemodynamics measured by the hemodynamics measuring device. The control device controls the blood pressure measuring device to measure the blood pressure on the basis of the amount of change and change trend in the pulse wave propagation time measured by the pulse wave propagation time measuring device, and the amount of change and change trend in the hemodynamics measured by the hemodynamics measuring device.

4. A blood pressure monitoring apparatus comprising:
-
blood pressure measuring means for measuring a blood pressure employing a cuff;
pulse wave propagation parameter measuring means for measuring a pulse wave propagation parameter;
hemodynamics measuring means for measuring hemodynamics; and
control means for controlling said blood pressure measuring means based on a change in the pulse wave propagation parameter measured by said pulse wave propagation parameter measuring means and a change in the hemodynamics measured by said hemodynamics measuring means, wherein said control means compares between a pulse wave propagation parameter change threshold that is stored in said control means to monitor an amount of said change in said pulse wave propagation parameter and detect a change in trend in said pulse wave propagation parameter, compares between a hemodynamics change threshold stored in said control means to monitor an amount of change in the hemodynamics, detects a change in trend in said hemodynamics measured, and updates said pulse wave propagation parameter change threshold based on results of the two comparisons with said thresholds and the detected change in trends. - View Dependent Claims (5)
