Intshayelelo:Uphando lwakutsha nje olubandakanya izixhobo zonyango luzise ingqwalasela eyongeziweyo kwizixhobo zonyango lwe-diathermy.Le ITG ibhaliwe ukunika abo bangaqhelananga nezixhobo zonyango lombane oluhamba rhoqo ulwazi olusisiseko lwethiyori ye-diathermy.
I-Diathermy yimveliso elawulwayo "yokufudumala okunzulu" phantsi kwesikhumba kwizicubu ezingaphantsi kwe-subcutaneous, izihlunu ezinzulu kunye namalungu ngenjongo yokwelapha.Kukho iintlobo ezimbini zezixhobo ze-diathermy kwimarike namhlanje: irediyo okanye i-high frequency kunye ne-microwave.Unyango lwe-Ultrasonic okanye i-ultrasound nayo iyindlela ye-diathermy, kwaye ngamanye amaxesha idibaniswa nokuvuselela kombane.I-Radio frequency (rf) i-diathermy inikwe i-frequency yokusebenza ye-27.12MH Z (i-wave elifutshane) yi-Federal Communications Commission.Iiyunithi zefrikhwensi yerediyo endala zabelwa i-frequency yokusebenza ye-13.56MH Z. I-Microwave diathermy yabelwa i-915MH Z kunye ne-2450MH Z njengezandi zokusebenza (ezi zikwangu-Microwave oven frequencies).
Isikhundla esikhoyo ngoku esingacwangciswanga soLawulo lokuTya kunye neDrugs kukuba isixhobo se-diathermy kufuneka sikwazi ukuvelisa ukushisa kwi-tissue ukusuka ubuncinane be-104 F ukuya kubuninzi be-114 F kubunzulu bee-intshi ezimbini ezingekho ngaphezu kwemizuzu engama-20.Xa izixhobo ze-diathermy zisetyenziswa, ukuphuma kwamandla kugcinwa ngaphantsi kwentlungu yesigulane.
Kukho iindlela ezimbini zokusebenzisa i-diathermy ephezulu okanye yerediyo-iDielectric kunye ne-Inductive.
1.Dielectric -Xa i-dielectric edityaniswe ne-diathermy isetyenziswa, ukwahluka kombane otshintshayo ngokukhawuleza kwenziwa phakathi kwee-electrode ezimbini ezivelisa indawo yombane etshintshana ngokukhawuleza phakathi kwee-electrode.I-electrodes ibekwe enye kwicala ngalinye okanye zombini kwicala elifanayo lenxalenye yomzimba ukuba iphathwe ukuze indawo yombane ingene kwiithishu zendawo echaphazelekayo yomzimba.Ngenxa yeentlawulo zombane ngaphakathi kweemolekyuli zezicubu, iimolekyuli zezicubu ziya kuzama ukulungelelanisa nommandla wombane oguqukayo ngokukhawuleza.Oku kuhamba ngokukhawuleza, okanye ukutshintshwa, kweeamolekyu, ezibangela ukungqubuzana okanye ukungqubana nezinye iimolekyuli, kuvelisa ubushushu kwizicubu.Amandla ombane ombane anqunywe ngumlinganiselo wokungafani phakathi kwee-electrode ezibekwe yiyunithi yokulawula amandla.Kuba i-frequency ayihlukanga, i-avareji yokukhutshwa kwamandla imisela ubunzulu bokufudumeza.Ii-electrode zidla ngokuba ziipleyiti zentsimbi ezincinci ezifakwe kumqamelo njengeendawo ezivaliweyo, kodwa zisenokwenziwa ngezinto ezibhetyebhetye ezifana nomnatha wocingo ukuze zijikwe ukuze zilingane inxalenye ethile yomzimba.
2.Intshukumo - I-Inductive coupled rf diathermy, i-frequency ephezulu yangoku iveliswa ngekhoyili ukuvelisa imagnethi ebuyela umva ngokukhawuleza.Ikhoyili idla ngokulinyazwa ngaphakathi kwisixhobo esidityaniswe neyunithi ye-diathermy ngengalo ehlengahlengiswayo.Umfaki-sicelo wenziwa ngeendlela ezahlukeneyo ukwenzela ukuba kube lula ukufaka isicelo kwindawo echaphazelekayo kwaye ubekwe ngqo phezu okanye ecaleni kwendawo eza kunyangwa.Intsimi yamagnetic eguqukayo ngokukhawuleza ibangela ukujikeleza kwemisinga kunye nemimandla yombane kwizicubu zomzimba, ukuvelisa ubushushu kwizicubu.Ukudityaniswa kwe-induction ngokuqhelekileyo kusetyenziswa kwingingqi ye-rf diathermy esezantsi.Ukuqina kokufudumeza kuphinda kugqitywe ngumyinge wokuphuma kwamandla.
