As shown in Figure 8, this device is three integration pick offs of cun,guan,chi, and the spacing that cun, guan and chi, three places at the wrist where the pulse is usually taken is three ones can be by the micro-adjusting mechanism adjustment.As measure short pulse and can under normal separation, detect; Measuring long pulse then gets final product by the spacing extension of governor motion with three probes.
4), pulse condition width detection technology
As shown in Figure 5, on the sensor probe surface, manage diametric(al) along the pulse and be cut with seven little pressure transducers of miniature beam with both ends fixed formula.By detecting the attenuation degree of beat pulse dynamics on the vascular diameter direction, the pulse condition width is calculated in interpretation.Because these seven little pick offs are separate, noiseless or interfere between its output signal, improved the resolution of signal, reduced measurement error.
5), the information classification method of multisensor
Shown in Fig. 5,8, this device is the compound versions of a plurality of pick offs, is made up of compound three the little pressure transducers of master reference in CUN and chi portion, is made up of compound seven the little pressure transducers of master reference in GUAN spot.Form by 16 standalone sensors altogether, export 16 groups of signals.These 16 groups of signals can be divided into three major types: the first kind is a cun, guan and chi, three places at the wrist where the pulse is usually taken master reference signal, be used for extracting and analyze the traditional Chinese medical science floating,, heavy pressure rating and pulse condition pressure waveform every basic parameter of time domain, frequency domain and transform domain; Second class is a framing signal, obtains on the little pressure transducer by the cun, guan and chi, three places at the wrist where the pulse is usually taken detecting head surface, according to the accurate position of size adjustment of little pressure transducer output amplitude; The 3rd class is the pulse condition width signal, is obtained by seven little pressure transducers on GUAN spot sensor probe surface, according to the thickness of the variation interpretation pulse condition of output amplitude.
6), three synchronous pressurizations of pick off equal pressure
Shown in Fig. 5,8, three pick offs of cun,guan,chi are exerted pressure to sering
When measuring pulse signal, the pressurization at random at random of finger that also can't the anthropomorphic dummy, resemble by searching for the pulse with fingers.By experiment repeatedly, we pressurization at random, etc. in displacement pressurization and the equal pressure pressurization standard a kind of method of equal pressure pressurization, promptly floating at pulse condition, in, the measuring in the process of heavy different pressures section, by the pressure signal of sensor feedback, three pick offs of cun, guan and chi, three places at the wrist where the pulse is usually taken are in measure three pulse conditions under the same pressure synchronously.

Under the cun, guan and chi, three places at the wrist where the pulse is usually taken normal separation, detect pulse condition;
Step 2. is judged
If the signal of CUN and chi portion is short pulse less than the 8-9 gram force threshold value of regulation, detection can be finished; If the signal of CUN and chi portion greater than 13-15 gram force threshold value, then might be long pulse, need carry out next step detection;
Step 3. is adjusted or loosening fixed screw (13)
By adjusting or loosening hold-down screw (13), make CUN and chi portion pick off along gathering sill (15) respectively to very little go up or chi under behind the direction shift position, measure cun go up and chi under the size of signal, whether whether reaching 8-9 gram force threshold value, to differentiate it be long pulse;
D), the concrete steps of pulse condition method for measuring width are:
Step 1. GUAN spot seven little pick offs of detecting head surface (16)
Surface at GUAN spot master reference probe (11) is compounded with seven little pick offs of detecting head surface (16) along the blood vessel diameter direction, measures with seven little pick offs of detecting head surface (16);
Step 2. is judged
According to the size of seven little pick offs of detecting head surface (16) signal, judge and distinguish the broad and rough and carefully narrow of pulse condition;
Step 3. is broad and rough and carefully narrow
Amplitude with that pick off of output peak signal in seven little pick offs of detecting head surface (16) is 100% standard value, if the signal output that little pick off more than 5 or 5 is arranged then is the envelope (17) of broad and rough pulse condition more than or equal to 70% of maximum amplitude; If the signal output of having only little pick off below 3 or 3 then is the envelope (18) of thin narrow pulse condition more than or equal to 70% of maximum amplitude.
