subject: Electronic Blood Pressure Monitor Manufacturers [print this page] Provided is an electronic blood pressure monitor manufacturers capable of realizing functions of blood pressure measurement in a shorter time and blood pressure measurement with more of correctness in the same and one construction thereof. The electronic blood pressure monitor manufacturers includes: an oscillometric measuring section capable of calculating a blood pressure with a high precision using much of biogenic information though a time is required since a blood pressure is calculated during a period in which the cuff pressure is gradually changed; and an SPD measuring section completing measurement in a short time though a fluctuation in precision of measurement arises according to an with less of biogenic information since individual difference a blood pressure is calculated using only one or several pulse waves. Since the oscillometric measuring portion performs a calibration processing for the SPD measuring section simultaneously during measurement thereof, calibrating operation a complicated can be practically excluded.
. The electronic blood pressure monitor manufacturers of claim 1, wherein the second blood pressure measuring portion further comprises a pressure setup unit that calculates a target pressure based on the cuff pressures detected by the pressure detector while the cuff pressure is increased by the cuff pressure controller and on the amplitudes of the pulse waves detected by the pulse wave detector at the timings of the cuff pressure detection during the cuff pressure increase and increases the cuff pressure to the target pressure using the cuff pressure controller, the target pressure being enough to assure an accurate blood pressure monitor manufacturers measurement by the second blood pressure measurement portion, wherein the pulse wave detected for providing the measured value of the pulse wave parameter is detected when or after the cuff pressure reaches the target pressure.
The electronic blood pressure monitor mnaufacturers of claim 1, wherein during the operation of the second blood pressure measuring portion the parameter measuring unit provides a measured value of at least one more pulse wave parameter, the function memory stores a plurality of the functions for the corresponding pulse wave parameters, the function selection units selects one of the sub-functions for each of the pulse wave parameters, and the second calculating unit generates a total function that provides a probability as a function of the relative cuff pressure and determines the relative cuff pressure for the calculation of the blood pressure monitor manufacturers as providing a maximum probability.
