Idumile kwizinto zakudalaicandelo lezonyangoKufuneka zixatyiswe, kuba kubandakanya ukuvuselelwa ngokomzimba, okwangoku kukho iimveliso ezininzi ezisemgangathweni weshishini, iimfuno zezinto zezixhobo ezahlukeneyo ziyakhethwa, izinto zesilicone azifani, ngoko ke ekubeni izinto zesilicone zisetyenziswa kwishishini lezonyango, yintoni esiyibiza ngokuba yisilicone yezonyango? Zithini izibonelelo ozaziyo!

Izinto zesilicone zinamandla athile okuzibamba kunye nozinzo oluhle, amandla azo aphezulu oomatshini, zisetyenziswa kakhulu kumashishini ahlukeneyo, ishishini lezonyango lelinye lazo, kwaye ukusuka kwizinto zezixhobo zonyango ukuya kuhlangabezana neemfuno ezithile zingasetyenziswa kwicandelo lezonyango. Umahluko usekwe kuxinano oluphezulu lwee-silicon molecular micro-pores, ii-molecular chain eziqinileyo kunye nozinzo oluphezulu.

Izizathu ezisibhozo zokuba i-silicone ibe yeyona nto ilungileyo yoyilo lwezixhobo zonyango:

1. Ikhonkco eliphambili le-oxygen ye-silicon libonelela ngozinzo oluhle kakhulu lobushushu.
I-Silicone inozinzo oluhle kakhulu kubushushu, nto leyo evumela izixhobo ukuba zigcine iipropati ezibalulekileyo nasemva kokubulala iintsholongwane. I-Silicone ingabulala iintsholongwane ngokubulala iintsholongwane ngomphunga oshushu kakhulu, ukubulala iintsholongwane nge-epoxy zane (EtO), okanye ngemitha ye-Y.

2. I-Silicone yinto engasebenziyo.
I-silicone idla ngokungangeni kulwelo lomzimba kunye neziyobisi, kwaye ayinavumba. Ulwakhiwo lwayo lweekhemikhali luhlangabezana nemigangatho ye-USP Class VI kunye ne-ISO 10993.

3. I-silicone ayinayo i-plasticizer okanye ezinye izongezo zendalo.
i-plasticizer okanye ezinye izongezo zendalo zinokuba nefuthe elibi ekuvelisweni kwamayeza, ukuba ezo zongezo zikhona, kunokwenzeka ukuba zifudukele kumayeza angamanzi kwaye ijeli ye-silica ayinazo izongezo ezifana ne-plasticizer okanye izongezo zendalo.

4. I-silicone ihlala ixesha elide.
I-Silicone inokuqina okuhle kunye nokubuyela kwimeko yesiqhelo emva kokubhoboza ukunciphisa ukudinwa kwezinto. Ezi mpawu ziphambili zinika i-silicone ubomi obude, nokuba iphantsi koxinzelelo oluguquguqukayo.

5. I-Silicone ine-modulus ephantsi.
I-silicone ifuna amandla amancinci okufaka ukuze kuphuculwe ukusebenza kakuhle kwesixhobo — okanye kube lula ukusihlanganisa xa sidityaniswe nezinye izinto.

6. I-silicone ingenziwa ibe bubunzima obahlukeneyo.
I-silicone inokubunjwa kwiintlobo ngeentlobo zobunzima ukuze ilungele izixhobo eziqinileyo kakhulu okanye ezithambileyo kakhulu, nto leyo ephakamisa amathuba okuphucula i-ergonomics kunye nentuthuzelo.

7. I-Silicone inoyilo oluhle lobuhle.
Ii-silicone elastomer ezininzi zibonakala ngokucacileyo kwaye zihlala zinombala lula.

8. I-Silicone kulula ukuyicubungula.
Ukongeza kubulukhuni bayo, intuthuzelo kunye neempawu zayo ezintle, i-silicone inikezela ngeendlela ezahlukeneyo zokwenza ngokwezifiso. Izixhobo zingafakwa kwizixhobo ezahlukeneyo kunye noyilo, ukusuka kwii-catheters zokufaka i-infusion ukuya kwiivalvu zokusika ukuya kwiimaski zokuphefumla. Ezinye iindlela zokwenza ngokwezifiso ziquka amandla okutsalwa, i-coefficient of friction, ixesha lokuphilisa kunye nobude.

Ukusetyenziswa kweemveliso zesilicone kwizixhobo zonyango.

Izixhobo ezidibana nolusu lomntu:
(1) Imaski yokuphefumla: ingakumbi imaski yesilicone ekufuneka inxitywe ixesha elide.
(2) Ukunyamekela amanxeba: Ijeli ye-silicone ilungele ulusu kwaye iyaphefumla, kwaye ayizukubangela ukwenzakala kwenxeba. Ke ngoko, ijeli ye-silicone ye-Magtu lukhetho olufanelekileyo lokufaka i-foam, i-scar paste, njl.njl.
(3) Iziphatho zezixhobo: Iziphatho ezithambileyo nezingatyibilikiyo mazifezekiswe kwizixhobo zonyango ekufuneka zibanjwe, njengeemela zotyando.

Izixhobo zokunxibelelana komzimba womntu:
Imaski yelaryngeal yesilicone: xa idibana ne-trachea, i-silicone ithambile kwaye yomelele ukuqinisekisa ukuba umoya uhamba kakuhle.
Ii-catheter ze-silicone: I-silicone ixhasa ukuveliswa kwee-tube bodies eziguquguqukayo kunye neebhaluni ezinamandla okutsalwa.
Ityhubhu yesisu yeSilicone: ubulukhuni obufanelekileyo, ityhubhu yesisu yeSilicone lukhetho olufanelekileyo kwizigulana.

Izixhobo zokunxibelelana negazi lomntu kunye nolwelo lomzimba:
I-catheter yesixhobo sokufaka: njengetyhubhu yepompo ye-peristaltic yepompo yokufaka, ityhubhu yangaphandle ye-catheter ye-silicone efakiweyo.
Izixhobo zokufaka i-infusion: ezifana ne-silicone rubber plug engenanaliti, i-silicone O-ring yesihluzi se-renal dialysis, njl.
Iiplagi zeplastiki kunye neevalvu ze-hemostatic kuzo zonke iintlobo zezinto ezisetyenziswayo kwezonyango xa zidibene nolwelo lwezonyango kunye nolwelo lomzimba.
Ukongeza, ijeli ye-silica ineendlela ezahlukeneyo zokusetyenziswa, ukusuka kwiilensi zokunxibelelana ukuya kwizixhobo zovavanyo lwezonyango ezinokunxitywa, ukusuka kwi-biopharmaceutical ukuya kuphando kunye nophuhliso lwe-vaccine, ijeli ye-silica ingasetyenziswa kakhulu kweli candelo.
