For how eliminating individual variation and carry out compensation data, domestic applications number be 201110144051.8 name be called that the patent of " for the individual calibration method of pulse wave continuous measurement estimation arteriotony and device " proposes and demarcate based on the coefficient in the sphygmomanometry of PWTT according to individual blood pressure situation.But its method can only estimate pressure value, and accuracy is not high enough; Meanwhile, scaling method is when PWTT time and last time differ greatly, and restarts the measurement of second fixed point blood pressure, has uncertainty in actual use, possibly cannot realize the continuous Measurement accuracy to user blood pressure.And the name that application number is 200410042522.4 is called that the patent of " a kind of adopt auto-compensation without cuff type continuous blood pressure detection method " is by measuring some characteristic quantities relevant to the pulse of measured, use cardiac output, the factor such as pressure, vagus nerve between tested position and sensor compensates sphygomanometer, trimming process is loaded down with trivial details, is difficult to realize in practical application.
The detection of blood pressure and the attitude of measured have direct relation, and for the test pose how controlling measured, along with the development of MEMS, a lot of patent all degree of will speed up sensor joins in system, as a source of information compensation.The name being 201210552217.4 as domestic applications number is called the patent of " sphygmomanometer system and blood pressure measuring method thereof ", detect its angle by 3D acceleration transducer when blood pressure detecting simultaneously, determine that measured detects the angle of arm and health, prompting measured take multiple measurements by same attitude, to reduce the detection error that attitude difference is brought.In this patent above-mentioned, angular pose detects and is only with aid prompting information, in the middle of the computing not participating in pressure value.And for example application number be 201310072380.5 name be called " for sphygomanometer measure Interference Suppression System and disturbance restraining method " patent, acceleration signal is added in tradition sleeve pocket type sphygomanometer, use the extraction of attitude signal thus suppress interference, this method will input the information such as height, brachium of measured in computational process, relative complex.Also comparatively simple on 3-axis acceleration information operating, be only the acceleration resultant calculated in space, actual test poor effect.
To sum up, PWTT method more traditional oscillographic method electric sphygmomanometer in principle and operation has very large advantage to exceed, but there is not the continuous BP measurement equipment based on PWTT of Clinical practice at present yet, mainly due to individual variation, measure time the gesture stability of measured and using method cause the relational expression between PWTT and ambulatory blood pressure values unstable, thus the accuracy of the pressure value that PWTT method is obtained and reliability not high enough.The measurement error that the non-normal use of measured causes, equally also appears in the use of the electric sphygmomanometer of traditional oscillographic method, therefore during hospital diagnosis disease, must re-start measurement to patient.This " curing from property ", i.e. the non-professionality of measuring process is also cause tele-medicine to be difficult to one of reason realized.
