By the sphygmomanometer, the acquisition of the blood vessel related information is not limited to the acquisition and measurement of a single arm, namely, the blood pressure and the pulse wave of the brachial artery (the medial groove of biceps brachii) and the posterior tibial artery (the back of the medial malleolus) of both legs are acquired simultaneously, so that the blood pressure measurement and the pulse wave acquisition of a plurality of parts of the body are not required to be performed by a plurality of sphygmomanometers, and the accuracy of the simultaneous measurement and acquisition of the plurality of parts is also ensured.

The angle of performing multi-dimensional blood pressure measurement and pulse wave acquisition is combined with the realization of the sphygmomanometer The following steps are carried out.

With the blood pressure monitor of the present invention, as shown in fig. 3, the duct interfaces 1131 on the side of the housing 113 of the main unit 110 are distributed, and four duct interfaces 1131, that is, the ports B1, B2, B3 and B4, are connected to the four cuffs 130 through the duct 111.

The four cuffs 130 respectively correspond to 4 body parts, specifically, the cuff 130 with a port B1 corresponds to a brachial artery of a left arm, the cuff 130 with a port B2 corresponds to a brachial artery of a right arm, the cuff with a port B3 corresponds to a posterior tibial artery of a left leg, the cuff with a port B4 corresponds to a posterior tibial artery of a right leg, the four cuffs 130 can be selectively activated by triggering on the button 115 or the screen 117 to inflate the cuff 130 in an activated state, measure blood pressure and acquire pulse waves of the corresponding body part, and the cuff 130 in a non-activated state cannot be inflated and acquired.

For the user, after the cuff 130 is tied, the measurement is started, and the blood pressure measurement and the pulse wave acquisition of one or more body parts can be completed without performing other operations.

To this end, a sphygmomanometer may be used to perform a variable pressure measurement and a constant pressure measurement process on one or more body parts.

(1) For the execution of the variable pressure measurement process, the MCU of the sphygmomanometer closes the air valve by controlling the air valve driving circuit 230, and controls the air pump driving circuit 220 to start the air pump, which inflates the activated cuff 130 through the tube 111.

When the pressure of the cuff 130 reaches the specified pressure range of the measurement parameter, the MCU controls the air pump driving circuit 220 to stop the air pump and controls the air valve to slowly deflate. This is the pressure transformation process within the cuff 130. The pressure sensor 210 collects the pressure signal of the whole pressure transformation process, and the conversion circuit 240 converts the pressure signal into a digital signal and transmits the digital signal to the MCU. The MCU analyzes the pressure signals to obtain measurements including systolic pressure, diastolic pressure, heart rate and pulse wave signals, and sends them to the remote server via the communication circuit 280. The remote server deploys a management system to compare and analyze this.

After the measurement is completed, the remaining gas in the cuff 130 is vented through the gas valve.

(2) For the execution of the constant-pressure measurement process, the MCU of the sphygmomanometer controls the air valve driving circuit 230 to close the air valve according to the setting, and controls the air pump driving circuit 230 to start the air pump, the air pump inflates the activated cuff 130 through the catheter 111, and when the pressure in the cuff 130 reaches the value specified by the measurement parameter, the MCU controls the air pump driving circuit 220 to stop the air pump.

After the pressure in the cuff 130 is stabilized, the pressure sensor 210 collects the pressure signal, and the conversion module 240 converts the pressure signal into a digital signal to be analyzed and processed by the MCU.
