Embodiment 1 pic 1， and approach ：① approach ；②；③、、 and ，；④ system ： to (4)；⑤： and 。 Embodiment 2

[0028] Example 1: see figure 1, The operation steps of this blood pressure measurement method combined with Korotkoff sound quality recognition and oscillometric method are as follows: ①Select the blood pressure measurement method; ②The computer controls the real-time monitoring of blood pressure to start; The hybrid blood pressure measurement optimization algorithm calculates the blood pressure value, saves and displays the measurement data; ④Remote real-time service system data monitoring: send the user's measurement data to the remote medical center service platform through the Internet (4); ⑤Intelligent signal analysis and processing: by computer The intelligent signal analysis and processing program automatically analyzes the blood pressure data and sends out alarm information to the user in time. Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0029] Steps above ① Select the blood pressure measurement meth...

Embodiment 3

[0050] Example 3: see figure 2 , the structure diagram of the data acquisition device for blood pressure and heart rate is an armband 5 or wristband 6 with a miniature microphone connected to the pressure sensor 7, the audio signal collected by the miniature microphone in the armband is output to the audio signal amplifier circuit 14, the output signal of the pressure sensor The analog signal is output to the AD converter 12 through the filter circuit 10 and the amplifying circuit 11; the digital signal after AD conversion is output to the USB interface 13; the data processor controls the micro air pump 8 and the controlled solenoid valve 9 through the USB interface 13. switch. The above audio signal amplification circuit includes a circuit for amplifying and processing the pulse wave sound signal collected by the miniature microphone and a miniature sensor, and whether the microphone is correctly placed at the pulse can be detected through the miniature sensor.

Embodiment 4

[0051] Example 4: see image 3 The structure of the blood pressure measurement system combining Korotkoff sound quality recognition and oscillometric method is as follows: a user 1 carries a blood pressure and heart rate data acquisition device 2 and is connected to a data processor 3, and the data acquisition device 2 is controlled by the data processor 3. The data of the user's blood pressure and heart rate are obtained, and the data processor 3 realizes data transmission with the remote medical center server 4 through the Internet.

[0052] see Figure 4 The control flow of the data processor 3 is as follows:

[0053] 1) start the user application software installed in the data processor 3;

[0054] 2) Select the corresponding measurement method according to user requirements: arm type or wrist type 5, 6;

[0055] 3) Set the measurement time, when the measurement time is up, start the micro air pump 8 to start inflation;

[0056] 4) Stop inflating after reaching the pre...

Abstract

The invention discloses a Korotkoff sound quality identification and oscillography combined blood pressure measurement method and a Korotkoff sound quality identification and oscillography combined blood pressure measurement system. The method comprises the following steps of: 1) selecting a blood pressure real-time measurement way; 2) starting the blood pressure real-time monitoring by a computer; 3) calculating a blood pressure value by a blood pressure measurement optimizing algorithm mixed with Korotkoff sound quality identification and oscillography, storing and displaying the measured data; 4) monitoring the data of a remote real-time service system; and 5) analyzing and processing an intelligent signal. The system is a blood pressure and heart rate data collecting device carried by a user and connected with a data processor; and the data processor is connected to a remote medical centre service platform via the internet. The invention can be used for measurement, storage and network transmission of blood pressures in families and hospitals so as to provide long-term stable health protection services for people to be measured.

Description

technical field [0001] The invention relates to a dynamic blood pressure and heart rate monitoring method and system, in particular to a blood pressure measurement method and system combining Korotkoff sound volume, timbre, tone recognition and oscillometric method. Background technique [0002] Compared with the occasional blood pressure measurement in the office, the ambulatory blood pressure monitoring removes the chance of the occasional blood pressure measurement, avoids the influence of emotions, exercise, eating, smoking, drinking and other factors on the blood pressure, and reflects the blood pressure more objectively and truly; ambulatory blood pressure can learn more Blood pressure data can actually reflect the change law of blood pressure throughout the day, mainly including systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate and their highest and lowest values, greater than or equal to 160 / 95mmHg or 140 / 90mmHg percentage and other...
