Lub tshuab electrocardiogram (ECG) qhia txog tus cwj pwm, feem ntau rau tib neeg lub plawv. Los ntawm kev soj ntsuam qhov hluav taws xob dhau lub sijhawm ntawm lub plawv, cov kws kho mob tuaj yeem nkag siab txog tus neeg mob txoj kev noj qab haus huv, vim muaj ntau yam kev ua pa thiab mob plawv tshwm sim thiab cuam tshuam qhov teeb meem ECG. Ntawm no, peb piav qhia cov kauj ruam ntawm txhua theem uas yuav tsum tau tsim koj tus kheej ECG Circuit thiab tom qab ntawd kaw lub teeb liab ECG.

Kauj Ruam 1: Kev Sib Txawv Sib Txawv Sib Txawv

Ua ntej, Ib qho Kev Sib Txawv Sib Txawv Sib Txawv yuav tsum tau tsim los suav rau qhov nce ntawm ib puag ncig 1000. Qhov nce yog qhov tseem ceeb hauv kev ua kom lub teeb liab kom ntseeg tau meej dua, nyeem tau cov teeb liab. Lub tshuab hluav taws xob tshwj xeeb no yuav muab rau koj ob lub tswv yim uas yuav tso cai rau koj teeb tsa cov electrodes kom raug thaum kawg ntawm kev tsim thiab nyeem ECG teeb liab.

Cheebtsam:

- (3) uA741 Op amp

- (4) 10 kohm resistors

- (3) 5 kohm resistors

Kauj Ruam 2: Tsis Ntxiv

Nruab nrab ntawm txhua theem, nws yog ib qho tseem ceeb ntxiv rau Kev Tiv Thaiv kom khaws lub teeb liab tawm ntawm txhua theem. Qhov no yuav pab txo suab nrov thoob plaws hauv kev tsim cov Circuit Court.

Cheebtsam:

- UA 741 Op amp

Kauj Ruam 3: Bandpass Lim

Kev tsim kho ntawm Bandpass Lim yog ib qho tseem ceeb hauv kev tso cai tsuas yog qee yam ntawm cov zaus uas dhau los ntawm Circuit Court mus rau qhov tso tawm. Rau ECG, thaj tsam ntawm 0.1 Hz txog 250 Hz yog qhov zoo tagnrho. Qhov Tsawg Dhau Lim yuav tso cai teeb liab qis dua 250 Hz dhau thiab High Pass Lim yuav tso cai teeb tsa siab dua 0.1 Hz dhau. Kev txiav tawm zaus sib npaug fc = 1/2piRC tuaj yeem siv los xam tus tiv thaiv thiab tus nqi hluav taws xob.

Cheebtsam:

- (1) uA741 Op amp

- (1) 6.8 kohm resistor

- (1) 160 kohm resistor

- (2) 0.1 uF capacitor

Kauj Ruam 4: Ntsis Lim

Ntxaib Ntxov Ntxov yuav tsum tau tsim los thaiv qhov zaus 60 Hz los ntawm kev hla lub Circuit Court. Qhov zaus no yuav tsum raug cais tawm vim tias nws feem ntau cuam tshuam nrog cov kab hluav taws xob thiab yog li nws tuaj yeem muaj peev xwm ua rau cuam tshuam nrog ECG teeb liab. Txhawm rau xaiv cov khoom siv, sib npaug 1/4piRC tuaj yeem siv tau.

Cheebtsam:

- (2) 27 kohm resistor

- (1) 13 kohm resistor

- (2) 50 nF capacitor

- (1) 100 nF capacitor

Kauj Ruam 5: Tsim Koj Li Circuit Court

Thaum kawg, txuas txhua theem ua ke! Nco ntsoov qhov ntxiv ntawm qhov tsis nyob nruab nrab ntawm txhua theem kom ntseeg tau tias khaws cia ntawm lub teeb liab. Kev tsim kho yuav siv qee qhov kev sim thiab ua yuam kev kom ntseeg tau tias txhua yam khoom siv tau raug muab tso rau hauv lub khob cij. Nws tuaj yeem pab ntsuas txhua tus tib theem ntawm oscilloscope kom pom tias txhua theem ua cov txiaj ntsig xav tau.

Kauj Ruam 6: Ntsuas ECG ntawm Tib Neeg

Tom qab ntawd koj tuaj yeem sim ntsuas koj li ECG Circuit tsim siv oscilloscope. Txuas ob qhov hluav taws xob rau koj pob taws thiab ib qho rau koj lub dab teg sab xis. Cov hmoov txhuas zoo mus rau pob taws sab laug, cov hmoov txhuas tsis zoo mus rau pob taws sab xis, thiab hauv av mus rau sab tes xis. Nco ntsoov xyuas yog tias koj cov xov hlau tau ua haujlwm uas koj tab tom siv rau lub zog txuas nrog rau cov xov hlau txuas nrog rau cov zis.
