Ⅰ. Ukubunjwa Komkhiqizo
Isakhiwo esiyisisekelo: isigaba sokufaka, isigaba se-amplifier, isifunda sokulawula, isigaba sokubonisa, isigaba sokurekhoda, isigaba sokunikezwa kwamandla, isigaba sokuxhumana
Isigaba sokurekhoda (ikhanda lokuphrinta, ipuleti lokuphrinta, umgqomo wephepha, njll.)
Isigaba sokubonisa (ibhodi lokubonisa, i-LCD)
Isigaba sokuphakelwa kwamandla (i-adaptha, ibhodi ye-adaptha, ibhethri)
Ingxenye yokuxhumana (i-usb interface, i-UART interface, njll.)
Ingxenye yokokufaka/yokukhulisa (i-lead wire interface, ibhodi lesiteshi)
Umjikelezo wokulawula (ibhodi elikhulu, ibhodi lokhiye, njll.)
Ⅱ. Ukwakhiwa Kwesijobelelo
Ⅲ. Okuyisisekelo
I-electrocardiogram (ECG) igrafu (ijika) erekhoda ukusuka phezulu komzimba izinguquko zamandla kagesi akhiqizwa inhliziyo phakathi nomjikelezo wenhliziyo ngamunye.
I-Electrocardiogram ingabonisa izinguquko ezingaba khona ze-bioelectric ngesikhathi sokukhiqiza, ukuqhutshwa kanye nokululama kwenjabulo yenhliziyo.
Odokotela baxilonga futhi banqume isimo sokusebenza senhliziyo kanye nezifo eziningi zenhliziyo nemithambo yegazi ezivela ezinguqukweni ze-bioelectrical zenhliziyo.
I-ECG yezinga lamazwe ngamazwe yamanje iwukuhola okujwayelekile, okwakhiwe imikhondo eyishumi nambili, ngakho-ke i-ECG evamile izobonisa imigqa yamagagasi ayishumi nambili. Ngokutholwa kwezimpawu ezivela ku-ECG ehola ishumi nambili, kungenzeka ukuthi ungaqondile ukukhomba indawo yemvelaphi kanye nokungajwayelekile kwesilonda senhliziyo. Isibonelo, izifo ezivame kakhulu i-myocardial infarction kanye ne-myocardial ischemia. (Qaphela: I-ECG lead ibhekisela ekubekweni kwama-electrode ebusweni bomzimba womuntu kanye nokuxhunywa kwama-electrode ku-amplifier lapho kulandelwa i-ECG; umthofu uwuhlobo lokuxhuma! I-electrode iyisisetshenziswa esihambisayo. Ama-electrode e-ECG ahlukaniswe abe ama-electrode esitho (4) kanye nesifuba.
● Iyini i-12-lead?
I-12 ehamba phambili ihlanganisa i-6 lead lead (I, II, III, i-aVR, i-aVL, ne-aVF) kanye ne-6 chest lead (V1 kuya ku-V6). Izitho zomzimba zibandakanya umkhondo ojwayelekile we-bipolar (I, II, no-III) nemikhondo ecindezelwe (aVR, aVL, ne-aVF). Imikhondo ye-bipolar iqanjwe ukuze kuqoshwe umehluko we-voltage phakathi kwamaleveli amabili
● Ukubaluleka komtholampilo kanye nokusebenza
- Ukubaluleka Clinical: bhala umsebenzi kagesi wenhliziyo yomuntu; ukusiza ukuxilonga i-arrhythmia, ischemia ye-myocardial, i-myocardial infarction, i-myocarditis, i-cardiomyopathy, ukutholakala kwegazi okwanele kwe-coronary artery, i-pericarditis, njll.; ukusiza ukunquma umphumela wezidakamizwa noma ukuphazamiseka kwe-electrolyte enhliziyweni; ukusiza ukunquma isimo sokuhamba kwenhliziyo okwenziwa.
- Kusetshenziswa kabanzi: ukuhlolwa komzimba okujwayelekile, ukuhlinzwa, ukulaliswa kwezinzwa, ukubonwa kwemithi, ezemidlalo, indawo yendiza nokunye ukuqapha inhliziyo kanye nokuhlenga iziguli ezigula kakhulu.
● Yimuphi umkhondo nomgudu womshini we-ECG?
Umshini we-ECG onemikhondo eyishumi nambili: umshini we-ECG okhethekile onenani eliphelele le-12 ejwayelekile emzimbeni, equkethe imikhondo yemilenze emi-3 ye-bipolar, imikhondo yemilenze emi-3 ecindezelwe unipolar, kanye nemikhondo yesifuba eyi-6. Isamba sihamba phambili siyi-12.
Ngakho-ke, ukuhola okuyishumi nambili akusona isici esihle somshini othile we-EKG, kodwa isici esiyisisekelo kakhulu!
Ngakho uyini umqondo weziteshi eziyishumi nambili emshinini we-ECG?
I-12-lead, njengoba kushiwo ngaphambili, izibonakalisa ngendlela ye-waveform yeziteshi eziyi-12, bese kufanele siphrinte idatha ye-waveform erekhodiwe, ngaleso sikhathi, imingcele embalwa ibalulekile: ukunemba kwe-waveform, ukucaca, kanye nesivinini sokuphrinta.
Uma iphepha lokurekhoda likhulu, ukucushwa kwanele, khona-ke imikhondo ye-12 yedatha ingaphrintwa ngesikhathi esifanayo, ngalesi sikhathi, izoshesha kunesiteshi esisodwa, iziteshi ezintathu, iziteshi eziyisithupha, ngokuqondile izikhathi ezingu-2 kuya kwezingu-12.
Okusho ukuthi, isiteshi esisodwa siwukuphrinta kwe-waveform eyodwa kuphela, iziteshi ezintathu ziphrinta ama-waveform amathathu, ngokufanayo, iziteshi eziyisithupha zizophrinta ama-waveform ayisithupha, umshini wesiteshi esiyishumi nambili uwukuphrinta amagagasi ayishumi nambili.
Isheke elifanayo, umshini wesiteshi esisodwa ozophrinta izikhathi eziyi-12 ukuze uphrinte wonke amagagasi eziteshi eziyi-12, kanti umshini weziteshi eziyi-12 uzophrintwa kanye wonke amagagasi eziteshi eziyi-12.
Indlela elula futhi eqondile yokubuka lokhu ukubuka indawo ye-cartridge yokuphrinta; ama-cardiometer ahlukene anezinombolo ezahlukene zemizila anobubanzi obuhlukene bephepha lokuphrinta.
