For fear of the influence of unstable factor, reduce the probability that error takes place.Preferably adopt the meansigma methods of 10 parameter values in embodiments of the present invention, promptly step 702 need repeat, till detecting 10 parameter values.
With the blood pressure measurement parameter M that is obtained, C and complex parameter Pc promptly can draw blood pressure by blood pressure computing formula: blood pressure=M * Pc+C, comprise systolic pressure and diastolic pressure.
Continue if desired to measure blood pressure, then repeat above-mentioned steps.
Need to prove that in blood pressure computing formula of the present invention: among blood pressure=M * Pc+C, coefficient M and C have reflected the parameter of each user and the relation between the blood pressure, vary with each individual.Therefore at user when using electronic auscultation apparatus of the present invention for the first time, need in calibration mode, determine these coefficients.Because coefficient M and C are different respectively for calculating systolic pressure and diastolic pressure, thus in calibration mode, to determine one group of parameter Msys and Csys respectively corresponding to systolic pressure, and corresponding to the one group of parameter Mdia and the Cdia of diastolic pressure.The method of determining these two groups of parameters can adopt any method of the prior art, and for example, a kind of method is to be used as the input value of Csys and Cdia with the empirical value of Csys and Cdia; The blood pressure that user utilizes standard-sphygmomanometer to record by input equipment input, and they are kept at memory element.Then, according to electrocardio, hear sounds and the photoelectricity pulse wave signal gathered, determine the meansigma methods of obtained complex parameter Pc; According to formula Msys=(systolic pressure-Csys)/Pc, and Mdia=(diastolic pressure-Cdia)/Pc calculates Msys and Mdia respectively, is kept in the memory element.
Another kind method is, measure at least two groups with reference to pressure value and complex parameter Pc for each user, respectively systolic pressure and diastolic pressure are set up the linear regression line of a personalization with the method for linear fit then, and definite coefficient Msys, Csys, Mdia and Cdia, deposit these coefficients in memory element at last, be used for calculating pre-measuring blood pressure.
Because method shown in Figure 7 can correspondence be applicable among the aforesaid method embodiment that so description is comparatively simple, not detailed part can be referring to the description of this description front appropriate section.
More than a kind of electronic auscultation apparatus provided by the present invention is described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
