Kushandiswa kweFirimu Capacitor
muCardiac Defibrillator
Defibrillation ndiyo chete nzira inoshanda yekurapa kufa kamwe kamwe kwemoyo
Cardiac defibrillator parizvino inoshandiswa zvakanyanya kiriniki yekununura michina.Inoshandisa pulsed ikozvino kuita pamwoyo, kushandisa magetsi ekuvhundutsa kurapwa, kubvisa arrhythmia, uye kudzoreredza moyo kune sinus rhythm..
Yayo kushanda musimboti kazhinji inotora RLC inonyorovesa nzira yekuburitsa, sezvakaratidzwa mumufananidzo:
| Yakajairika data | |
| Energy | 100~500J |
| Voltage | 2000 ~ 5000VDC |
| Capacitance | 32 ~ 200UF |
| Discharge load | 20Ω/50Ω/100Ω |
| Maximum pulse current | 100~1kA |
Kutanga kubhadharisa simba rekuchengetedza capacitor C kuita kuti capacitor iwane imwe huwandu hwesimba.Panguva yekurapa defibrillation, C, inductance L uye muviri wemunhu (mutoro) zvakabatanidzwa munhevedzano kuita kurapa kwekuvhundutsa kwemagetsi pamwoyo wemunhu.
●Simba rakachengetwa
Simba remagetsi rinochajirwa mumudziyo wekuchengetedza simba risati rasvika defibrillation shock.Hukama huri pakati pesimba rakachengetwa mu capacitor uye voltage ye capacitor:
E=½ cu²
Yekushandisa mu defibrillator, iyo CRE firimu capacitor ine yakasarudzika yakasarudzika dhizaini, iyo ine yakakwirira kuita kwakanakira:
Kuenzaniswa ne10,000 nguva dzehupenyu hwesevhisi pamusika, iyo yakakosha firimu chimiro dhizaini inoita yekuchaja uye yekuburitsa hupenyu nguva dzinopfuura makumi matatu,000 nguva.
Tichifunga nezvekushandiswa kwenzvimbo isina chokwadi uye ine hutsinye senge yekunze, inotora yakakosha anti-humidity uye yakakwirira tembiricha yekudzivirira dhizaini, ine kuvimbika kwakanyanya.
Kunyanya kune diki vhoriyamu dhizaini yekunze otomatiki defibrillator (AED) (senge inobatwa ruoko), uchishandisa yakakwirira simba density zvinhu, vhoriyamu uye uremu i50% idiki pane yakajairika dhizaini.

Mamiriro ekuedzwa:
1. Static bvunzo mamiriro: rekodhi rekodhi, kurasikirwa, yakaenzana inoteedzana kuramba.Iwo static paramita anorekodhwa ega ega 10,000 nguva dzekuchaja uye kuburitsa.Kuti uve nechokwadi chechokwadi chekurekodha data, tembiricha ye capacitor inofanirwa kunge iri padyo sezvinobvira kune ambient tembiricha paunenge uchiunganidza.Muedzo unoitwa pamusiyano wekushisa we ≤5 ℃.
