Nrov los ntawm thaum ubkev kho mob tebs yuav tsum tau muaj nqis, vim tias muaj kev kho lub cev, tam sim no muaj ntau yam khoom lag luam, cov khoom siv ntawm cov khoom siv sib txawv raug xaiv, cov khoom siv silicone tsis zoo ib yam, yog li txij li cov khoom siv silicone hauv kev lag luam kho mob, peb hu ua silicone kho mob yog dab tsi?

Cov khoom siv silicone muaj qee qhov kev ua tau zoo adsorption thiab ruaj khov zoo, nws lub zog kho tshuab siab, yog siv dav hauv ntau yam lag luam, kev lag luam kho mob tsuas yog ib qho ntawm lawv, thiab los ntawm cov khoom siv kho mob kom ua tau raws li qee qhov kev xav tau tuaj yeem siv hauv kev kho mob. Qhov sib txawv nyob rau hauv qhov ceev ntawm silicon molecular micro-pores, muaj zog dua molecular saw thiab ruaj khov dua.

Yim qhov laj thawj uas silicone yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv kho mob:

1. Silicon oxygen lub ntsiab saw hlau muab kev ruaj khov thermal zoo heev.
Cov roj silicone muaj kev ruaj khov zoo heev, ua rau cov khoom siv tseem muaj cov khoom tseem ceeb txawm tias tom qab ua kom huv. Cov roj silicone tuaj yeem ua kom huv los ntawm kev tua kab mob los ntawm cov pa kub siab, kev tua kab mob epoxy zane (EtO), lossis Y hluav taws xob.

2. Silicone yog ib yam khoom inert.
Feem ntau cov silicone tsis nkag mus rau hauv cov kua dej thiab tshuaj hauv lub cev, thiab tsis muaj ntxhiab. Nws cov qauv tshuaj lom neeg ua tau raws li USP Class VI thiab ISO 10993 tus qauv.

3. Silicone tsis muaj plasticizer lossis lwm yam organic additives.
cov tshuaj yas lossis lwm yam khoom siv organic yuav muaj qhov cuam tshuam tsis zoo rau kev xa cov tshuaj, yog tias cov khoom siv ntxiv muaj, nws tuaj yeem hloov mus rau cov tshuaj kua thiab silica gel tsis muaj cov khoom siv ntxiv xws li cov tshuaj yas lossis cov khoom siv organic.

4. Silicone yog ruaj khov.
Cov silicone muaj qhov ywj pheej zoo thiab rov qab zoo tom qab tho qhov kom txo qhov qaug zog ntawm cov khoom. Cov yam ntxwv tseem ceeb no ua rau silicone siv tau ntev, txawm tias nyob hauv kev ntxhov siab dynamic.

5. Silicone muaj modulus qis.
Silicone xav tau lub zog ntxig tsawg kawg nkaus kom txhim kho kev ua haujlwm zoo ntawm lub cuab yeej - lossis yooj yim dua rau kev sib sau ua ke thaum ua ke nrog lwm cov khoom.

6. Silicone tuaj yeem ua rau ntau yam tawv.
Silicone tuaj yeem ua pwm ntau yam tawv kom haum rau cov ntaub ntawv uas tawv dhau lossis mos dhau, ua rau muaj peev xwm txhim kho ergonomics thiab kev nplij siab.

7. Silicone muaj kev xav zoo nkauj.
Ntau cov silicone elastomer yog pob tshab thiab feem ntau yuav yooj yim muaj xim.

8. Silicone yooj yim rau kev ua.
Ntxiv rau nws qhov nyuaj, kev nplij siab thiab cov yam ntxwv zoo nkauj, silicone muaj ntau yam kev xaiv kho kom haum. Cov ntaub ntawv tuaj yeem siv rau ntau yam khoom siv thiab cov qauv tsim, los ntawm cov catheters infusion mus rau cov qhov txhab thiab cov ntaub npog ua pa. Lwm cov kev xaiv kho kom haum suav nrog lub zog tensile, coefficient of friction, curing time thiab elongation.

Kev siv cov khoom siv silicone hauv cov cuab yeej kho mob.

Cov cuab yeej uas kov tau tib neeg daim tawv nqaij:
(1) Lub npog ntsej muag ua pa: tshwj xeeb tshaj yog lub npog ntsej muag silicone uas yuav tsum tau hnav ntev.
(2) Kev saib xyuas qhov txhab: Silicone gel zoo rau daim tawv nqaij thiab ua pa tau zoo dua, thiab yuav tsis ua rau raug mob ntxiv rau qhov txhab. Yog li ntawd, Magtu silicone gel yog qhov kev xaiv zoo rau kev siv ua npuas ncauj, tshuaj pleev qhov txhab, thiab lwm yam.
(3) Cov tes tuav ntawm cov cuab yeej siv: Yuav tsum tau ua kom tau raws li cov tes tuav mos thiab tsis plam rau cov cuab yeej kho mob uas yuav tsum tau tuav, xws li riam phais.

Cov cuab yeej rau kev sib cuag ntawm lub cev tib neeg:
Lub ntsej muag silicone laryngeal: nyob rau hauv kev sib cuag nrog lub trachea, silicone mos thiab muaj zog kom ntseeg tau tias txoj hlab pa du.
Cov catheter silicone: Silicone txhawb kev tsim cov raj yas uas yoog tau thiab cov npas muaj zog tensile siab.
Lub raj mis silicone gastric: qhov nyuaj tsim nyog, lub raj mis silicone gastric yog qhov kev xaiv zoo rau cov neeg mob.

Cov cuab yeej siv los kov cov ntshav thiab cov kua dej hauv lub cev tib neeg:
Catheter ntawm lub cuab yeej infusion: xws li lub raj mis peristaltic ntawm lub twj tso kua mis infusion, lub raj sab nraud ntawm lub catheter silicone ntxig.
Cov khoom siv ntawm cov cuab yeej infusion: xws li cov roj hmab silicone ntsaws tsis muaj koob sib koom ua ke, silicone O-ring ntawm lub lim dej dialysis, thiab lwm yam.
Cov yas ntsaws thiab cov qhov dej hemostatic hauv txhua yam khoom siv kho mob uas sib cuag nrog cov kua dej kho mob thiab cov kua dej hauv lub cev.
Tsis tas li ntawd xwb, silica gel muaj ntau yam kev siv, los ntawm cov iav sib cuag mus rau cov khoom siv kuaj mob hnav tau, los ntawm biopharmaceutical mus rau kev tshawb fawb thiab kev tsim tshuaj tiv thaiv kab mob, silica gel tuaj yeem siv dav hauv daim teb.
