Cov qauv zoo, siab dabtsi yog khoov thiab lub zog tensile, tuaj yeem tau khoov ntawm yuav, cov ntaub qhwv tuaj yeem ua rau lub raj, hom thiab qhwv. Nws yog qhov yooj yim rau kev khiav lag luam, tsuas xav tau cov dej kub ib txwm tsis muaj, tsis muaj cuab yeej siv cua sov, nws tuaj yeem kho tau hauv lub sijhawm luv. Tus qauv zoo thiab sim elasticity.
7. Cov khoom siv dav dav: kev txhim kho pob txha orthopedic orthopedics, cov cuab yeej pab txhawb ntxiv, cov cuab yeej txhawb nqa, thiab cov chaw tiv thaiv hauv zos rau kev hlawv.
8. Txoj kev kho mob kom nrawm, ua kom zoo sai sai rau hauv 2-3 feeb, ua tawv sai sai, sib zog hauv 3-5 feeb, thiab tuaj yeem thev hnyav tom qab 20 feeb. Los kho lub ntsuas dej kom sov, lub sijhawm ua kom tawv tawv tuaj yeem hloov kho, dej ntsuas tau nce siab, lub sijhawm ua tawv tawv yog luv, dej kub tau qis, thiab lub sijhawm ua tawv tawv ntev. Thaum cov bandage yog soaked, muaj tsawg kawg nkaus gypsum poob. Lub sijhawm ziab kom nrawm thiab nrawm hauv 36 teev. Hloov tau, kub tsis kam (+40 ° C) thiab siab txias (-40 ° C), tsis muaj tshuaj lom, tsis muaj kuab lom, tsis ua xua.
9. Kev tiv thaiv ib puag ncig. Nws yog noo noo-tiv taus, noo noo-tiv taus, tsis muaj tshuaj lom, tsis ua mob thiab tsw qab tom qab kev teeb tsa.
