Nkhani: Diathermy

Chiyambi:Kafukufuku waposachedwapa wokhudza zipangizo zachipatala achititsa chidwi kwambiri pa zipangizo zachipatala.ITG iyi yalembedwa kuti ipatse omwe sadziwa zida zamagetsi zamagetsi zamagetsi zambiri chidziwitso chofunikira cha chiphunzitso cha diathermy.

Diathermy ndi kupanga kolamulidwa kwa "kutentha kwambiri" pansi pa khungu mu minyewa ya subcutaneous, minofu yakuya ndi mfundo zochizira.Pali mitundu iwiri ya zida za diathermy pamsika lero: wailesi kapena ma frequency apamwamba ndi ma microwave.Akupanga kapena ultrasound mankhwala ndi mtundu wa diathermy, ndipo nthawi zina pamodzi ndi kukondoweza magetsi.Radio frequency (rf) diathermy imapatsidwa ma frequency a 27.12MH Z (short wave) ndi Federal Communications Commission.Magawo akale a mawayilesi amaperekedwa pafupipafupi 13.56MH Z. Microwave diathermy imapatsidwa 915MH Z ndi 2450MH Z ngati ma frequency ogwiritsira ntchito (awanso ndi mafunde a uvuni wa Microwave).

Mkhalidwe wamakono wa Food and Drug Administration ndikuti chipangizo cha diathermy chiyenera kutulutsa kutentha mu minofu kuchokera ku 104 F mpaka kufika pa 114 F pa kuya kwa mainchesi awiri osapitirira mphindi 20.Pamene zida za diathermy zikugwiritsidwa ntchito, mphamvu yamagetsi imasungidwa pansi pa ululu wa wodwalayo.

Pali njira ziwiri zogwiritsira ntchito diathermy yapamwamba kapena wailesi - Dielectric ndi Inductive.

1. Dielectric -Dielectric cod-diathermy ikagwiritsidwa ntchito, kusiyanitsa kwamagetsi kosinthasintha kumapangidwa pakati pa maelekitirodi awiri kutulutsa gawo lamagetsi losinthasintha pakati pa maelekitirodi.Ma electrode amayikidwa mbali imodzi kumbali iliyonse kapena onse kumbali imodzi ya gawo la thupi kuti athandizidwe kuti magetsi alowe muzitsulo za dera lokhudzidwa la thupi.Chifukwa cha mphamvu zamagetsi mkati mwa mamolekyu a minofu, mamolekyu a minofu amayesa kudzigwirizanitsa ndi magetsi omwe akusintha mofulumira.Kusuntha kofulumira kumeneku, kapena kusinthana, kwa mamolekyu, kumayambitsa mikangano kapena kuwombana ndi mamolekyu ena, kumatulutsa kutentha m'thupi.Mphamvu yamagetsi yamagetsi imatsimikiziridwa ndi kuchuluka kwa kusiyana komwe kulipo pakati pa maelekitirodi omwe amaikidwa ndi unit power control.Popeza ma frequency sasintha, kuchuluka kwa mphamvu kumatsimikizira kukula kwa kutentha.Ma elekitikilo nthawi zambiri amakhala mbale zachitsulo

2. Kulimbikitsa - Mu inductive coupled rf diathermy, ma frequency apamwamba amapangidwa kudzera pa koyilo kuti apange maginito osinthika mwachangu.Koyiloyo nthawi zambiri imakulungidwa mkati mwa chogwiritsira ntchito cholumikizidwa ndi gawo la diathermy ndi mkono wosinthika.Wofunsirayo amapangidwa m'njira zosiyanasiyana kuti agwiritse ntchito mosavuta kudera lomwe likukhudzidwa ndipo amayikidwa mwachindunji kapena pafupi ndi malo omwe amathandizidwa.Mphamvu ya maginito yomwe imabwerera mofulumira imapangitsa kuti mafunde oyendayenda ndi magetsi azilowa m'thupi, zomwe zimapangitsa kutentha m'thupi.Kulumikizana kwa induction nthawi zambiri kumagwiritsidwa ntchito kumunsi kwa rf diathermy.Kuchuluka kwa Kutentha kumatsimikiziridwanso ndi mphamvu zamagetsi.
