I-depressor yolwimi sisixhobo esiqhelekileyo soxilongo lwezonyango, esisetyenziswa ngokuyintloko kwiimviwo zomlomo kunye nomqala. Imigaqo yayo yoyilo isekelwe kubuchwephesha obulula kunye ne-ergonomics, ejolise ekuphuculeni ukuchaneka kweemviwo kunye nokuthuthuzela isigulane.
Ngokwesakhiwo, isicinezeli solwimi siqhele ukuba yiplati ecaba eyenziwe ngomthi, iplastiki okanye intsimbi. Izinto zokuxinzelela ngolwimi zomthi zisetyenziswa kakhulu ngenxa yexabiso eliphantsi, indalo elahlayo, kunye nokungaqhubi kakuhle kobushushu. Iiplastiki zokuxinzelela ulwimi zikhaphukhaphu kwaye zilungele ukuvala inzala ngokuphindaphindiweyo. I-Metal language depressors (efana nentsimbi engatyiwayo) ihlala ihleli kwaye isetyenziswa ngokuqhelekileyo kwizicwangciso zonyango lobuchwephesha. Isitshixo soyilo lwabo silele ekulungiseni ububanzi kunye nobude: ububanzi buqhelekile phakathi kwe-1-2 cm, ukuqinisekisa ukudakumba okusebenzayo kolwimi ngaphandle kokuphazamisa indlela yomoya; ubude ngokuqhelekileyo phakathi kwe-10-15 cm, okwenza kube lula ukuba ugqirha abambe kwaye angene nzulu emlonyeni.
Umgaqo womatshini wokucinezela ulwimi ubonakala kuyilo olusicaba. Ngokusebenzisa uxinzelelo, i-depressor yolwimi iqhubela phantsi ulwimi, iveze umva womqala kunye neetoni, iququzelele ukubonwa kukagqirha kwizilonda okanye izinto zangaphandle. Ngaphaya koko, izicinezeli zolwimi zihlala zigudiswa ukunqanda ukukrwela i-mucosa yomlomo, ebonisa iingqwalasela ze-ergonomic.
Kwinkqubo yeklinikhi, indlela i-depressor yolwimi esetyenziswa ngayo ichaphazela ngokuthe ngqo ukusebenza koviwo. Oogqirha badla ngokufaka uxinzelelo oluthambileyo kwisiseko solwimi kwi-engile ye-45 degree, beqinisekisa indawo ecacileyo yokujonga kunye nokunciphisa isicaphucaphu sesigulane. Nangona kukho inkqubela ekhawulezileyo kubugcisa bezonyango bale mihla, abantu abacinezela ulwimi bahlala besisisixhobo esiyimfuneko soxilongo ngenxa yokulula, ukusebenza kakuhle, kunye neendleko eziphantsi. Kwixesha elizayo, ukuhambela phambili kwenzululwazi yemathiriyeli kunokuvumela ukuphuculwa okuthe kratya koyilo lokucinezela ulwimi, olufana nokusetyenziswa kwezixhobo ezilwa neentsholongwane okanye izinto ezinokubola, ukomeleza ukhuseleko kunye nobuhlobo bokusingqongileyo.
