Embodiment 1
[0059] Embodiment 1 static blood pressure measurement
[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiment 1.
[0061] Step 1: If figure 1 As shown, the inner fixing belt 12 is tightly wrapped around one side of the subject's limb, the sensor stabilizing structure 120 is closely attached to the artery, and the fixing belt 11 is tightened at the same time, ready to start the test.
[0062] Step 2: Start the test through the control button on the host 1, the start signal is transmitted to the fixed belt 11 through the wire 2, the inflation / deflation control unit starts to inflate, and multiple sensors in the multi-parameter physiological signal acquisition module synchronously record the inflation process various physiological signal parameters.
[0063] Step 3: stop inflating until the Korotkoff sound sensor 14 detects no Korotkoff sound vibration signal. The inflation / deflation control...
Embodiment 2
[0072] Embodiment 2 ambulatory blood pressure measurement
[0073] The test steps of this embodiment are consistent with those of Embodiment 1, and will not be repeated here.
[0074] The measurement device involved comprises: a multi-parameter physiological signal acquisition module (10), a signal processing module (20), a central processing module (30), a control module (50), a full waveform record display analysis module (60), a storage module ( 70), network module (80). Among them, the multi-parameter physiological signal acquisition module (10), the signal processing module (20), the central processing module (30), the control module (50), the storage module (70) and the network module (80) are all reasonably and effectively fixed on the outer layer belt (11). There is a display screen on the outer layer fixing belt (11), which can display information such as working status and parameter values.
[0075] The working principle of this embodiment is as follows.
