Kugwiritsa Ntchito Filimu Capacitor
mu Cardiac Defibrillator
Kutsegula mtima (defibrillation) ndiyo njira yokhayo yothandiza pochiza imfa yadzidzidzi ya mtima
Chotsukira mtima (defibrillator) chimagwiritsidwa ntchito kwambiri pochiza matenda. Chimagwiritsa ntchito mphamvu yamagetsi kuti chigwire ntchito pamtima, chigwiritse ntchito mphamvu zamagetsi, chichotse arrhythmia, ndikubwezeretsa mtima ku sinus rhythm..
Mfundo yake yogwirira ntchito imagwiritsa ntchito njira yotulutsira madzi ya RLC, monga momwe zasonyezedwera pachithunzichi:
| Deta yachizolowezi | |
| Mphamvu | 100~500J |
| Voteji | 2000~5000VDC |
| Kuchuluka kwa mphamvu | 32~200UF |
| Kutulutsa mphamvu | 20Ω/50Ω/100Ω |
| Kugunda kwakukulu kwamakono | 100~1kA |
Choyamba, yambitsani mphamvu ya capacitor C kuti capacitor ipeze mphamvu inayake. Pa chithandizo cha defibrillation, C, inductance L ndi thupi la munthu (load) zimalumikizidwa motsatizana kuti zichite chithandizo chamagetsi pamtima wa munthu.
●Mphamvu yosungidwa
Mphamvu yamagetsi imalowa mu chipangizo chosungira mphamvu isanayambe kugwedezeka kwa defibrillation. Ubale pakati pa mphamvu yosungidwa mu capacitor ndi voltage ya capacitor:
E=½ cu²
Pogwiritsa ntchito mu defibrillator, CRE film capacitor ili ndi kapangidwe kake kapadera, komwe kali ndi ubwino wapamwamba wa magwiridwe antchito:
Poyerekeza ndi nthawi ya utumiki wa nthawi 10,000 pamsika, kapangidwe kake ka filimu yapadera kamapangitsa kuti moyo wa kuchaja ndi kutulutsa ukhale woposa nthawi 30,000
Poganizira momwe zinthu zilili komanso zovuta monga panja, imagwiritsa ntchito njira yapadera yolimbana ndi chinyezi komanso kukana kutentha kwambiri, yomwe ndi yodalirika kwambiri.
Makamaka pa kapangidwe kakang'ono ka chipangizo chodzitetezera chakunja (AED) (monga zofunikira pamanja), pogwiritsa ntchito zipangizo zokhala ndi mphamvu zambiri, mphamvu ndi kulemera kwake zimakhala zochepa ndi 50% kuposa kapangidwe kachizolowezi.
