Defibrillator capacitor

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 tawonetsera pachithunzichi:

Zambiri zofananira
Mphamvu	100 ~ 500J
Voteji	2000 ~ 5000VDC
Kuthekera	32-200 UF
Kutulutsa katundu	20Ω/50Ω/100Ω
Kuthamanga kwamphamvu kwambiri	100-1 kA

Choyamba limbani capacitor yosungirako mphamvu C kuti capacitor ipeze mphamvu zina.Panthawi ya 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 pamapangidwe ang'onoang'ono opangira zida zakunja zodziwikiratu (AED) (monga zofunikira zapamanja), pogwiritsa ntchito zida zamphamvu zamagetsi, voliyumu ndi kulemera kwake ndi 50% yaying'ono kuposa kapangidwe kokhazikika.

Tengani zinthu zathu ndi opanga awiri wamba pamsika kuti ayesenso kufananitsa komweko.Pansi pa kugwiritsa ntchito kutentha kwakukulu ndi chinyezi, mankhwala athu amakhala ndi moyo wautali.

Zoyeserera:
1. Mayeso osasunthika: kuchuluka kwa mbiri, kutayika, kukana kofananira.Ma static parameters amalembedwa nthawi zonse 10,000 pakulipiritsa ndi kutulutsa.Pofuna kutsimikizira kulondola kwa kujambula kwa deta, kutentha kwa capacitor kuyenera kukhala pafupi kwambiri ndi kutentha kozungulira pamene mukusonkhanitsa.Kuyesedwa kumachitika pa kutentha kwa ≤5 ℃.
2. Zinthu zoyeserera zamphamvu: chilengedwe 55 ℃ 95%, voteji yoyezetsa 2200V.DC, nthawi yolipira 4S, nthawi yotulutsa 1S, kusintha kwamagetsi DV/DT = 4.7V/μS, kugunda pachimake 940A, kulipira ndi kutulutsa nthawi 20000.Mayeso othamangitsa ma pulse pano ndi 1.6 nthawi zamakampani athu pano (585A).
3. Njira yoyesera: magawo a capacitor static asanayesedwe.
