Yuav Ua Li Cas Xaiv Cov Txhuam Txhuam Hluav Taws Xob

 

Rau cov pos hniav sib txawv, cov txhuam hniav sib txawv hluav taws xob yuav tsum tau xaiv.

 

Cov hniav enamel yog cov khoom hnyav tshaj plaws hauv tib neeg lub cev, tab sis kev siv mus sij hawm ntev kuj yuav ua rau qee qhov ntuj hnav thiab txawm tias puas. Qee tus neeg muaj kev txhim kho enamel zoo thiab tsis nquag hnav thiab puas; Qee cov neeg muaj cov enamel tsis zoo, lossis tetracycline dental fluorosis, uas yooj yim dua hnav.

 

Cov hniav nrog enamel abrasion yuav rhiab heev, thiab cov tsos mob ntawm dentine hypersensitivity thiab txawm mob yuav tshwm sim thaum ntsib kub thiab txias qaub thiab qab zib.

 

Raws li qhov sib txawv ntawm cov hniav sib txawv, qhov kev ua tau zoo ntawm cov txhuam hniav hluav taws xob yuav tsum ntsuas thaum yuav khoom:

(1) Bristle rounding tus nqi

Cov bristles ntse dhau yog yooj yim ua rau cov pos hniav puas. Cov neeg uas muaj cov pos hniav nyias / cov pos hniav raug pom zoo kom siv cov txhuam hniav hluav taws xob uas muaj qhov sib npaug siab.

Cov txhuam hniav ntawm cov txhuam hniav hluav taws xob tam sim no siv cov nylon filament bristles, thiab cov lus qhia ntawm cov txhuam hniav yuav tsum sib npaug. Qhov zoo ntawm cov tshuaj txhuam hniav hluav taws xob zoo dua, qhov siab dua qhov sib npaug ntawm cov bristles, siv tau yooj yim dua; thiab cov bristles nrog qis rounding tus nqi zoo ib yam li "lub tsev so txhuam hniav tsis zoo". , Qee zaum kuv txhuam kuv cov pos hniav thiab ua rau kuv lub qhov ncauj puv los ntshav.

Ib yam li ntawd, qhov sib npaug ntawm cov bristles yog tsawg, cov bristles yog sharper, thiab lawv muaj feem yuav hnav cov hniav, thiab cov neeg uas rhiab rau cov hniav lawv tus kheej yog feem ntau hnav cov hniav.

 

(2) Softness thiab hardness ntawm bristles

Qhov nyuaj ntawm cov bristles, qhov muaj zog ntawm 'brushing zog', qhov zoo dua cov nyhuv tu, tab sis kev siv tsis raug tuaj yeem ua rau cov hniav thiab cov pos hniav puas; lub softer lub bristles, ntau tus phooj ywg rau cov pos hniav, thiab ntau "kev kho mob tom qab txhuam hniav" yog tshwj xeeb yog mos los tiv thaiv cov pos hniav los ntawm kov qhov chaw phais. mob. Txawm li cas los xij, vim tias cov txhuam hniav zoo li no tsis muaj kev ua kom huv txaus, cov txhuam hniav mos tsis tuaj yeem txhuam cov quav hniav ntawm cov hniav. Nws tsuas yog pom zoo siv rau lub sijhawm luv luv tom qab kev phais.

Rau cov txhuam hniav zoo tib yam, peb pom zoo cov txhuam hniav; tab sis feem ntau ntawm cov txhuam hniav hluav taws xob nyob rau hauv kev ua lag luam muaj nruab nrab-nyuaj bristles thiab tawv bristles. Vim li cas?

Vim tias qhov kev vibration zaus ntawm cov txhuam hniav hluav taws xob ceev ceev, cov txhuam hniav uas muag heev tsis yooj yim kom rov qab sai sai rau lawv cov deformation nyob rau hauv high-frequency vibration, thiab kev tu efficiency tsis txaus. Yog li ntawd, hluav taws xob hniav actuator yuav tsum tau cov bristles kom muaj me ntsis hardness thiab muaj zog elasticity. Yog li ntawd, rau cov tib neeg zoo tib yam, cov txhuam hniav hluav taws xob nrog nruab nrab tawv bristles yog qhov zoo, thiab rau cov neeg uas muaj cov pos hniav rhiab heev, tseem muaj cov txhuam hniav muag muag hauv khw xaiv los ntawm.

 

(3) Txhuam taub hau thiab vibration txoj kev

Hluav taws xob txhuam hniav nyob rau hauv kev ua lag luam feem ntau muab faib ua ob lub taub hau txhuam thiab sib piv txoj kev vibration. Ib qho yog lub taub hau txhuam plaub hau zoo ib yam li cov txhuam hniav zoo tib yam. Txoj kev sib txuam vibration yog kev co raws li qhov ntev ntawm tus txhuam hniav (simulated Pap txhuam txoj kev, kab rov tav vibration tu Gingival sulcus), los yog kev co perpendicular mus rau lub axis ntev ntawm tus txhuam hniav (simulating ntsug txhuam txoj kev, ntsug kev co los ntxuav qhov sib txawv ntawm cov hniav. ). Lub amplitude thiab vibration ntawm no txhuam taub hau yog me me, thiab nws yog ntau haum rau cov neeg uas rhiab pos hniav.

Lub taub hau txhuam hniav ntawm lwm tus txhuam hniav hluav taws xob yog lub taub hau txhuam txhuam, thiab qhov sib txuam kev vibration hom yog compound vibration, uas yog, ntsug hniav vibration + reciprocating rotation hom. Vim hais tias txoj kev vibration yog complex, lub amplitude thiab vibration xav yuav loj dua lub square txhuam taub hau, tab sis kev tu efficiency thiab tu muaj peev xwm kuj muaj zog. Yog hais tias cov neeg uas muaj cov pos hniav rhiab siv cov txhuam hniav hluav taws xob, nws raug nquahu kom xaiv ib lub taub hau txhuam txhuam.
