Taw qhia:Kev tshawb nrhiav tsis ntev los no hais txog cov cuab yeej kho mob tau ua rau muaj kev mob siab rau cov khoom siv kho mob diathermy.Qhov ITG no tau raug sau los muab cov neeg tsis paub nrog cov cuab yeej siv hluav taws xob ntau zaus kom paub txog qhov kev xav ntawm diathermy.
Diathermy yog kev tswj hwm ntawm "sib sib zog nqus cua sov" hauv qab ntawm daim tawv nqaij hauv cov ntaub so ntswg subcutaneous, cov leeg sib sib zog nqus thiab cov pob qij txha rau kev kho mob.Muaj ob hom khoom siv diathermy nyob rau hauv kev ua lag luam niaj hnub no: xov tooj cua lossis siab zaus thiab microwave.Ultrasonic los yog ultrasound therapy kuj yog ib daim ntawv ntawm diathermy, thiab qee zaum ua ke nrog hluav taws xob stimulation.Xov tooj cua zaus (rf) diathermy tau muab lub sijhawm ua haujlwm ntawm 27.12MH Z (nthwv dej luv) los ntawm Tsoom Fwv Teb Chaws Kev Sib Txuas Lus Commission.Cov qub xov tooj cua zaus zaus tau muab qhov kev khiav hauj lwm zaus ntawm 13.56MH Z. Microwave diathermy raug muab 915MH Z thiab 2450MH Z raws li kev khiav hauj lwm zaus (cov no kuj yog Microwave qhov cub frequencies).
Tam sim no txoj hauj lwm tsis raws cai ntawm Lub Chaw Tswj Xyuas Khoom Noj thiab Tshuaj yog tias cov khoom siv diathermy yuav tsum muaj peev xwm ua kom sov hauv cov ntaub so ntswg los ntawm qhov tsawg kawg nkaus ntawm 104 F mus rau qhov siab tshaj plaws ntawm 114 F ntawm qhov tob ntawm ob ntiv tes tsis pub dhau 20 feeb.Thaum siv cov khoom siv diathermy, cov zis hluav taws xob tau khaws cia hauv qab qhov mob ntawm tus neeg mob.
Muaj ob txoj hauv kev ntawm kev thov siab lossis xov tooj cua zaus diathermy - Dielectric thiab Inductive.
1. Dielectric -Thaum siv cov dielectric coupling diathermy, qhov sib txawv ntawm qhov sib txawv ntawm qhov hluav taws xob sai yog tsim los ntawm ob lub electrodes uas ua rau cov hluav taws xob hloov pauv sai ntawm cov electrodes.Cov electrodes tau muab tso rau ib qho ntawm txhua sab lossis ob qho tib si ntawm tib sab ntawm lub cev los kho kom cov hluav taws xob nkag mus rau cov ntaub so ntswg ntawm thaj tsam ntawm lub cev.Vim yog cov nqi hluav taws xob nyob rau hauv cov ntaub so ntswg molecules, cov ntaub so ntswg molecules yuav sim ua kom lawv tus kheej nrog cov hluav taws xob hloov pauv sai.Qhov kev txav ceev no, lossis kev hloov pauv, ntawm cov molecules, ua rau muaj kev sib txhuam lossis kev sib tsoo nrog lwm cov molecules, ua kom sov hauv cov ntaub so ntswg.Lub zog hluav taws xob hauv hluav taws xob yog txiav txim siab los ntawm qhov sib txawv ntawm qhov muaj peev xwm ntawm cov electrodes teeb tsa los ntawm chav tswj fais fab.Txij li cov zaus tsis sib txawv, qhov nruab nrab lub zog tso zis txiav txim siab qhov siv ntawm cov cua sov.Cov electrodes feem ntau yog me me hlau daim hlau mounted hauv cushion zoo li enclosures, tab sis tej zaum yuav ua los ntawm ib tug saj zawg zog cov ntaub ntawv xws li hlau mesh kom lawv yuav contoured kom haum ib feem ntawm lub cev.
2. Inductive - Nyob rau hauv inductive txuas rf diathermy, siab zaus tam sim no yog generated los ntawm ib tug coil los tsim ib tug ceev reversing magnetic teb.Lub kauj yog ib txwm raug mob hauv ib qho applicator txuas nrog lub diathermy chav tsev los ntawm ib caj npab adjustable.Tus neeg thov kev pab yog tsim nyob rau hauv ntau yam ntaub ntawv kom yooj yim ntawm daim ntawv thov mus rau qhov chaw muaj kev txhawj xeeb thiab yog positioned ncaj qha los yog ib sab ntawm lub cheeb tsam yuav tsum tau kho.Kev sib nqus nrawm nrawm nrawm nrawm nrawm nrawm nrawm thiab hluav taws xob teb rau hauv cov ntaub so ntswg ntawm lub cev, ua kom sov hauv cov ntaub so ntswg.Induction coupling feem ntau yog ua haujlwm nyob rau hauv qis rf diathermy cheeb tsam.Kev siv cua sov yog rov txiav txim siab los ntawm qhov nruab nrab lub zog tso zis.
