Measurement process: Referring to FIG. 4, a method for measuring an intelligent fingerprint type packet measurement electronic sphygmomanometer is as follows:

Step 5: Press the memory key and the test result is saved to the data storage unit. The present invention relates to allowing a subject to first test a blood pressure value by auscultation and manually storing the value in a data storage unit as a calibration value before using the electronic sphygmomanometer for the first measurement of blood pressure, and then the subject is registered by the fingerprint recognition unit and will register The fingerprint of the person is stored in the data storage unit, and then the fingerprint authentication module stores the recorded fingerprint and the data storage unit for comparison and authentication.

working principle:

Amplitude coefficient algorithm,

Systolic pressure calculation method: average pressure *a;

Diastolic blood pressure calculation method: average pressure *b; because each person's a and b parameter values are different, if user 1 measures the true blood pressure value: systolic blood pressure: 120mmhg, diastolic blood pressure 80mmhg, then user 1 before blood pressure measurement The meter interface manually inputs the high and low voltage 120mmhg, 80mmhg two values, press the power button, the fingerprint identifies the user 1, and the user's real high and low voltage value is 120mmhg, 80mmhg. After inflation and deflation, since the average pressure is the pressure value at the moment of maximum pulse wave amplitude, it is a fixed value. If the software calculates that the average pressure of user 1 is 200 mmhg, then the software will change the above a and b parameters, taking the most Close to 120mmhg, the parameter set of 80mmhg is used as the calculation of user 1, and the measurement result is displayed. For user 1 systolic pressure a=60%, b=40%; thus, next time user 1 measures blood pressure again, since the machine can fingerprint identify user 1, The parameter calculations obtained from the last calibration are automatically selected so that each user has a different a and b parameter values after calibration.
