The varistor employing Plasma inpouring technology that above-mentioned cantilever beam-cilium declines in structure injects the formation of boron ion , varistor is provided with four and four varistor resistances are equal.
The acoustic sensor processed based on MEMS technology is filled by electronic type stethoscope based on MEMS technology as pickup Put, pick up heart vibration signal, by signal processing circuit board, the vibration signal of pickup is processed, can be at liquid crystal display Show heart rate number of times on screen in real time, and restore audio signal by audio frequency processing circuit, promote speaker sounding, thus can To hear heart sound at earphone head end, and the big I of sound is regulated by button, can be by electronic auscultation additionally by bluetooth module Device is connected with host computer, and detection signal is sent to host computer, restores heartbeat waveform at host computer window.
MEMS electronic type stethoscope in the present invention, first passes through and sensor microstructure is optimized design, through MEMS Technique have developed the higher sonic transducer of pickup sensitivity, additionally can clearly carry out auscultation by ears pipe, simultaneously can be from Directly read heart rate in LCDs, and also can gather the cardiechema signals in a period of time, show the heart by upper computer end Jumping waveform, these functions substantially increase practicality and the convenience of this MEMS electronic stethoscope, therefore this MEMS electronic auscultation Device more advantage in Clinical practice.
When carrying out cardiac auscultation, heart sound vibration signal through silicone oil conduction extremely bionical cilium, causes bionical by entrant sound cap Cilium deflection, the vibration signal experienced is passed to high accuracy cantilever beam, makes cantilever beam upper stress change by bionical cilium, Make the varistor resistance on cantilever beam change accordingly, drive the favour stone being made up of varistor on whole cantilever beam The output voltage values of bridge differential circuit synchronizes to change, thus reflects heart sound situation of change.
Described MEMS sonic transducer micro structure is that the piezoresistive effect combining bionics principle and semi-conducting material is designed Coming, be made up of high accuracy cantilever beam and bionical cilium, wherein high accuracy cantilever beam structure is to utilize soi wafer partly to lead through MEMS Body micro-processing technology is developed, and utilizes ICP plasma etching technology to etch centroplasm gauge block on a silicon substrate and both sides size is complete Two exactly the same cantilever beams, are utilized respectively Plasma inpouring technology and inject boron ion formation 4 at the two ends of every cantilever beam Varistor, and the resistance of varistor is the most equal, is connected into the Hui Si of detection cardiechema signals between varistor by lead-in wire Energising bridge circuit, bionical cilium is firm plastic cartridge, imitates fishes lateral line organ, when underwater signal acts on Fish side line During the neuromast sensory receptor of organ, motile cilium can glance off, and making sensory cell obtain stimulates, and stimulates by sensory nerve fine Dimension, is delivered to medulla oblongata through nervus lateralis, so that Fish obtain perception to underwateracoustic tone signal.According to this bionics principle, Utilize micro-adhesive technology by bionical cilium strong bond in the middle of cantilever beam structure centroplasm gauge block, when heart sound vibration letter When number acting on bionical cilium, bionical cilium glances off, and it is outstanding that the vibration signal experienced is passed to high accuracy by bionical cilium Arm beam, makes cantilever beam upper stress change, and makes the varistor resistance on cantilever beam change accordingly, drives whole outstanding The output voltage values of the Wheatstone bridge differential circuit being made up of varistor on arm beam synchronizes to change, thus accurate response Go out cardiechema signals situation of change.
When electronic stethoscope carries out auscultation, the analog voltage signal of Wheatstone bridge output is through wire transmission to multistage filter Ripple device and amplifier chip, filter out clutter, obtains pure amplification voltage signal, enters central die and processes, passes through algorithm Calculating heart rate number of times, in liquid crystal display screen display, digital voltage signal is sent into audio processing chip by central die simultaneously, After digital voltage signal is reduced into simulated audio signal by many weighted-voltage D/A converters, by promoting speaker to send out after Audio power amplifier Sound, thus heart sound is transferred to human ear.When needs are at computer end display heartbeat waveform, start bluetooth even by mode selecting key Connection function, is connected electronic stethoscope with computer end host computer, sends initiation command, the central authorities of electronic stethoscope by host computer Chip is started working, and the digital voltage signal collected is sent to host computer, and host computer processes after receiving signal, Host computer window restores heartbeat waveform, and after collecting setting capacity, upper computer end is automatically stopped reception, and sends stopping Order is to central processing element.
It is an advantage of the current invention that following some:
(1) by sensor microstructure is optimized design, MEMS technology high accuracy processing is utilized so that this electronics is listened Examine device pickup sensitivity to be greatly improved, can substantially collect second heart sound.
(2) audio frequency processing circuit and speaker are added.Make the acoustical signal after noise reduction filtering by double after amplifying Syrinx can be transferred to human ear, and the big I of sound is regulated by button, it is achieved thereby that clear auscultation.
(3) the heart rate number of times of tested personnel can accurately be read in real time from LCDs, it is not necessary to again by tradition Count the heart rate that converts so that doctor's auscultation process is convenient accurately.
(4) cardiechema signals collected can be delivered to computer end by bluetooth by this stethoscope, is demonstrated by host computer Clearly heart sound waveform, beneficially doctor's analysing patient's condition and the development of tele-medicine.
