Kugwiritsa ntchito Film Capacitor
mu Cardiac Defibrillator
Defibrillation ndiyo njira yokhayo yochizira imfa yadzidzidzi yamtima
Cardiac defibrillator pakali pano amagwiritsidwa ntchito kwambiri zida zopulumutsira zachipatala.Imagwiritsa ntchito pulsed current kuti igwire mtima, imagwiritsa ntchito mphamvu zamagetsi, kuthetsa arrhythmia, ndikubwezeretsanso mtima ku sinus rhythm..
Mfundo yake yogwirira ntchito imagwiritsa ntchito njira yotulutsa RLC, monga momwe tawonera pachithunzichi:
| Zambiri zofananira | |
| Mphamvu | 100 ~ 500J |
| Voteji | 2000 ~ 5000VDC |
| Kuthekera | 32-200 UF |
| Kutulutsa katundu | 20Ω/50Ω/100Ω |
| Kuthamanga kwamphamvu kwambiri | 100-1kA |
Choyamba limbani capacitor yosungirako mphamvu C kuti capacitor ipeze mphamvu zina.Pa chithandizo cha defibrillation, C, inductance L ndi thupi la munthu (katundu) zimalumikizidwa motsatizana kuti achite chithandizo chamagetsi pamtima wamunthu.
●Mphamvu zosungidwa
Mphamvu yamagetsi yomwe imayikidwa mu chipangizo chosungira mphamvu musanayambe kugwedezeka kwa defibrillation.Ubale pakati pa mphamvu zosungidwa mu capacitor ndi voteji ya capacitor:
E=½cu²
Pogwiritsa ntchito mu defibrillator, CRE film capacitor ili ndi mapangidwe apadera, omwe ali ndi ubwino wapamwamba:
Poyerekeza ndi nthawi 10,000 za moyo wautumiki pamsika, kapangidwe kake kakanema kapadera kamapangitsa kuti nthawi zolipiritsa ndi kutulutsa nthawi zambiri zizikhala nthawi zopitilira 30,000.
Poganizira kugwiritsa ntchito malo osatsimikizika komanso owopsa monga kunja, imatenga mawonekedwe apadera odana ndi chinyezi komanso kutentha kwambiri, komwe kumakhala kodalirika kwambiri.
Makamaka kapangidwe kakang'ono ka voliyumu yakunja yodziwikiratu (AED) (monga zofunikira m'manja), pogwiritsa ntchito zida zopangira mphamvu zambiri, voliyumu ndi kulemera kwake ndi 50% yaying'ono kuposa kapangidwe wamba.
