Background technology
Pulse condition collecting device is mainly used in the noinvasive pulse condition and detects, and can be placed in any one one of radial artery cun,guan,chi as required and detect pulse condition information.Exist " the best is followed the example of pressure " during traditional Chinese medical science feeling the pulse, under this pressure, will experience maximum amplitude and morphological characteristic the most clearly.Many key characters of pulse condition are surveyed just in this state.Follow the example of pressure and be greater than or less than optimum, pulse amplitude or the intensity experienced all will reduce, and morphological characteristic also can fog.Therefore, following the example of pressure will reasonably choose.How choose reasonable is followed the example of pressure has crucial effects to the development of traditional Chinese medical science pulse condition collecting device.
The key that objectifies of pulse wave spectrum is obtaining of high-quality pulse signal.Along with the continuous progress of sensor technology, designed increasing pulse image sensor." the doctor's pulse-feeling sensing device " that Chinese patent 89107657.3 is involved.This device is with the media of sense capsule as feeling the pulse, and the sense capsule contacts the arteries and veins position of human body, and the pulse signal that obtains is transferred to pressure transducer through the sensing body canal, converts the signal of telecommunication to by pressure transducer then.The weak point of this device is: adopt the usual pressure pick off, the arteries and veins shape signal of being gathered only can can't extract enough detailed arteries and veins shape signal for the simple pulse condition diagnosis of minority provides foundation, the automatic adjusting of the pressure of can not realizing feeling the pulse.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy to carry, the self-regulating pulse condition collecting device of pressure of can realizing feeling the pulse.
For this reason, this utility model adopts following technical scheme:
A kind of cuff formula Chinese medicine pulse harvester, comprise the pulse image sensor that places on the cuff, sensor interface circuitry, capture card, computer and air-channel system, the pulse signal that pulse image sensor is gathered is through after the processing of sensor interface circuitry, be admitted to computer by capture card, air-channel system comprises the cuff that links to each other by gas piping each other, air pump, quick release valve, electromagnetic valve, electromagnetic valve and vent valve are formed the unit of exitting at a slow speed, air pump, quick release valve links to each other with computer by drive circuit respectively with electromagnetic valve, and vent valve links to each other with gas piping via electromagnetic valve.
As preferred implementation, described sensor interface circuitry comprises preamplifier, voltage follower, first low pass filter, the one A/D ALT-CH alternate channel, high pass filter, the second low pass filtered device, main amplifier and the 2nd A/D ALT-CH alternate channel, by the pulse pressure signal via preamplifier after, be divided into two-way, one the tunnel handles the back via voltage follower and low pass filter obtains direct current pulse pressure signal, be admitted to an A/D ALT-CH alternate channel, another road is admitted to main amplifier after via the high pass filter and second low pass filter, is admitted to the 2nd A/D ALT-CH alternate channel by the interchange pulse wave signal of main amplifier output.
Pulse condition collecting device of the present utility model can be simulated the traditional Chinese medical doctor and be pushed maneuver, realize pressurizeing automatically, gathering in real time pulse signal, its air-channel system design makes cuff that the pick off parcel is pressed in human body radial artery place, pick off firmly is attached to not influenced by human body shake etc., can obtain stable pulse pressure fast.

The specific embodiment
1, system hardware population structure
The Chinese medicine pulse acquisition system mainly comprises pulse image sensor, sensor interface circuitry, and A/D capture card USB7360, several sections such as cuff formula gas circuit compression system and computer software storage and processing, as shown in Figure 1.
Pulse transducer is selected special-purpose pulse image sensor, requires it stable, good reproducibility, and direct current linearity height, stable output signal is disturbed little; Air-channel system is divided into then that air pump is inflated, electromagnetic valve is exitted slowly and the fast venting of air valve three parts, and the signal of computer output inflation or venting carries out corresponding action through A/D capture card control air-channel system; Sensor interface circuitry then is divided into two-way with sensor output signal, direct current pulse pressure signal with exchange pulse wave signal, two-way is handled output respectively through A/D capture card input computer, carry out oscillography, storage, feature extraction and pulse condition identification.
2, sensor interface circuitry
The pulse image sensor interface circuit is shown in block diagram 2, comprise constant current source power supply, preamplifier, voltage follower, first low pass filter, the one A/D ALT-CH alternate channel, high pass filter, the second low pass filtered device, main amplifier and the 2nd A/D ALT-CH alternate channel, by the pulse pressure signal via preamplifier after, be divided into two-way, one the tunnel handles the back via voltage follower and low pass filter obtains direct current pulse pressure signal, be admitted to an A/D ALT-CH alternate channel, another road is admitted to main amplifier after via the high pass filter and second low pass filter, is admitted to the 2nd A/D ALT-CH alternate channel by the interchange pulse wave signal of main amplifier output.
The design of 3 air-channel systems
Use air-channel system to control pulse pressure among the design, as shown in Figure 3.
Air-channel system is formed by connecting by mini air pump, quick release valve, miniature electromagnetic valve, vent valve, cuff and some sebific ducts, mini air pump is used for inflating to whole air-channel system, quick release valve is used for quick venting, electromagnetic valve and vent valve are formed the unit of exitting at a slow speed, be embedded with pick off on the cuff, be tied to the human wrist place.
Its design of drive circuit as shown in Figure 4, diode is used for earial drainage among the figure, electrochemical capacitor can carry out filtering, when reducing the quick air releasing threshold switch to the interference of circuit.Isolate with photoelectrical coupler in the circuit, suppress of the influence of the switch of electromagnetic valve circuit.
During system works when needs increase pulse pressure, can open air pump inflates, gas flow constantly increases in the cuff, the pressure that makes pick off be pressed in the human wrist pulse increases, when pressure increases to desired value, stop air pump, carry out data acquisition, when needs descend a pulse pressure unit, can use the unit of exitting slowly, slowly the unitary opening and closing of exitting are controlled by driving circuit for electromagnetic valve, vent valve then be the gas flow of waiting for its air inlet when arriving the certain pressure value with regard to automatic deflation, discharge quantity is less, when exitting rapidly, needs then use the quick air releasing valve cell, this unit is by the control of air valve drive circuit, and discharge quantity is big, and speed is fast.
The design of this air-channel system makes cuff that the pick off parcel is pressed in human body radial artery place, pick off firmly is attached to be not subjected on the human body skin human body shake etc. to influence, and can obtain stable pulse pressure fast.
