Nhanganyaya:Ongororo dzenguva pfupi yapfuura dzinosanganisira michina yekurapa dzakaunza kutarisisa zvakanyanya kumidziyo yekurapa diathermy.Iyi ITG yakanyorwa kuti ipe avo vasina kujairana nepamusoro frequency magetsi ekurapa michina ruzivo rwakakosha rwe diathermy theory.
Diathermy ndiyo inodzorwa kugadzirwa kwe "deep heat" pasi peganda mu subcutaneous tishu, yakadzika tsandanyama uye majoini nekuda kwekurapa.Iko kune marudzi maviri emidziyo yedhiathermy pamusika nhasi: redhiyo kana yakakwirira frequency uye microwave.Ultrasonic kana ultrasound therapy zvakare imhando ye diathermy, uye dzimwe nguva inosanganiswa nemagetsi kukurudzira.Radio frequency (rf) diathermy inopihwa frequency yekushanda ye27.12MH Z (short wave) neFederal Communications Commission.Maredhiyo eredhiyo ekare akapihwa frequency yekushanda ye13.56MH Z. Microwave diathermy inopihwa 915MH Z uye 2450MH Z semafambiro ekushanda (aya zvakare maMicrowave oven frequencies).
Chimiro chazvino chisina kurongeka cheFood and Drug Administration ndechekuti mudziyo wedhayathermy unofanirwa kuburitsa kupisa munyama kubva padiki pa104 F kusvika pahupamhi hwe114 F pakadzika kwemainji maviri musingapfuure maminetsi makumi maviri.Kana midziyo yedhiathermy ichishandiswa, simba rinobuda rinochengetwa pazasi pemukumbaridzo wemurwere.
Pane nzira mbiri dzekushandisa yakakwirira kana radio frequency diathermy - Dielectric uye Inductive.
1.Dielectric -Kana dielectric yakasanganiswa diathermy ikashandiswa, inokurumidza kuchinjika vhezheni musiyano inogadzirwa pakati pema electrode maviri achigadzira nekukurumidza kuchinjana kwemagetsi munda pakati pemagetsi.Maelectrode anoiswa rimwe divi rimwe nerimwe kana ose ari maviri kudivi rimwe chete rechikamu chemuviri kuti arapwe kuitira kuti nzvimbo yemagetsi ipinde mumatishu enzvimbo ine chekuita nemuviri.Nekuda kwemachaji emagetsi mukati mematishu mamorekuru, mamorekuru etishu anoedza kuzvibatanidza nemunda wemagetsi unokurumidza kuchinja.Uku kukurumidza kufamba, kana kuchinjana, kwemamorekuru, zvichikonzera kukonana kana kubonderana nemamwe mamorekuru, kunoburitsa kupisa mumatishu.Simba remumunda wemagetsi rinotariswa nehuwandu hwekusiyana kwezvinogona pakati pema electrode akaiswa neyuniti simba rekutonga.Sezvo frequency isina kusiyanisa, avhareji simba rekubuda rinotarisa kusimba kwekudziya.Maelectrodes anowanzo mahwendefa esimbi madiki akaiswa mucushion seakavharirwa, asi anogona kugadzirwa nezvinhu zvinochinjika sewaya mesh kuitira kuti akwanise kutenderedzwa kuti akwane chimwe chikamu chemuviri.
2.Inductive - In Inductive coupled rf diathermy, high frequency current inogadzirwa kuburikidza necoil kugadzira inokurumidza kudzosera magineti.Iyo coil inowanzokuvadzwa mukati memushandisi wakasungirirwa kune diathermy unit neruoko runogadziriswa.Munyoreri anogadzirwa nenzira dzakasiyana siyana kuti zvive nyore kunyorera kunzvimbo inobatwa uye anoiswa zvakananga pamusoro kana padivi penzvimbo inorapwa.Iyo inokurumidza kudzoka magineti inokonzera kutenderera kwemhepo uye magetsi emagetsi mumatishu emuviri, achigadzira kupisa mumatishu.Induction coupling inowanzo shandiswa munzvimbo yepasi rf diathermy.Kusimba kwekupisa kunotsanangurwa zvakare neavhareji simba rekubuda.
