Kushandiswa kweFirimu Capacitor
muCardiac Defibrillator
Kubvisa tsinga muropa ndiyo nzira chete inoshanda yekurapa rufu rwemwoyo kamwe kamwe
Muchina we defibrillator wemwoyo unoshandiswa zvakanyanya pari zvino. Unoshandisa pulsed current kushanda pamoyo, kushandisa electric shock therapy, kubvisa arrhythmia, uye kudzorera moyo ku sinus rhythm..
Nheyo yayo yekushanda inonyanya kushandisa nzira yekubvisa mvura yeRLC, sezvakaratidzwa mumufananidzo:
| Ruzivo rwakajairika | |
| Simba | 100~500J |
| Voltage | 2000~5000VDC |
| Kukwanisa | 32~200UF |
| Mutoro wekuburitsa | 20Ω/50Ω/100Ω |
| Kupisa kwemhepo kwakanyanya | 100~1kA |
Tanga wachaja capacitor yekuchengetera simba C kuti capacitor iwane simba rakati. Panguva yekurapa defibrillation, C, inductance L nemuviri wemunhu (load) zvakabatana zvakatevedzana kuti zviite kurapwa kwemagetsi pamoyo wemunhu.
●Simba rakachengetwa
Simba remagetsi rinopinda mumudziyo wekuchengetera simba risati rasvika defibrillation shock. Hukama huripo pakati pesimba rakachengetwa mu capacitor nevoltage ye capacitor:
E=½ cu²
Pakushandiswa mu defibrillator, CRE film capacitor ine dhizaini yakasarudzika yakagadzirirwa, ine zvakanakira zvekushanda kwepamusoro:
Zvichienzaniswa nehupenyu hwebasa hunosvika zviuru gumi mumusika, dhizaini yechimiro chefirimu chaiyo inoita kuti hupenyu hwekuchaja nekuburitsa hupfuure kanopfuura zviuru makumi matatu
Tichifunga nezvekushandiswa kwenzvimbo dzisina chokwadi uye dzakaoma dzakadai sekunze, inoshandisa dhizaini yakasarudzika yekudzivirira hunyoro uye kudzivirira kupisa kwakanyanya, iyo yakavimbika zvakanyanya.
Kunyanya pakugadzirwa kwechinhu chinodzikisa simba rekunze (AED) (sezvinodiwa nemaoko), uchishandisa zvinhu zvine simba rakawanda, huwandu nehuremu zvidiki ne50% pane dhizaini yakajairika.

Mamiriro ebvunzo:
1. Mamiriro ekuyedza asingachinji: kugona kurekodha, kurasikirwa, kuramba kwakaenzana. Maparamita asingachinji anorekodhwa kagumi rega rega pakuchaja nekuburitsa data. Kuti kuve nechokwadi chekuti data rakanyorwa zvakanaka, tembiricha ye capacitor inofanira kunge iri pedyo netembiricha yemhepo panguva yekuunganidza. Bvunzo inoitwa patembiricha yakasiyana ye ≤5 ℃.
2. Mamiriro ekuedza anochinja: nharaunda 55 ℃ 95%, voltage ye terminal yekuedza 2200V.DC, nguva yekuchaja 4S, nguva yekuburitsa 1S, chiyero chekuchinja kwevoltage DV/DT=4.7V/μS, pulse peak current 940A, kuchaja uye kuburitsa 20000.
