Okudumile kusukela ezikhathini zasenduloinsimu yezokwelaphaKufanele zibhekwe njengenani, ngoba kuhilela ukuvuselelwa ngokomzimba, okwamanje kunemikhiqizo eminingi yezinga lomkhakha, izidingo zezinto zokwakha zemishini ehlukene ziyakhethwa, izinto ze-silicone nazo azihlukile, ngakho-ke njengoba izinto ze-silicone embonini yezokwelapha, lokho esikubiza ngokuthi i-silicone yezokwelapha yiziphi izinzuzo ozaziyo!

Izinto ze-silicone zinokusebenza okuthile kokumunca kanye nokuqina okuhle, amandla azo aphezulu okusebenza, zisetshenziswa kabanzi ezimbonini ezahlukene, imboni yezokwelapha ingenye yazo kuphela, futhi kusukela ezintweni zezokwelapha ukuze kuhlangatshezwane nezidingo ezithile kungasetshenziswa emkhakheni wezokwelapha. Umehluko usebuningini obuphezulu bama-micro-pores e-silicon molecular, amaketanga aqinile e-molecule kanye nokuqina okuphezulu.

Izizathu eziyisishiyagalombili ze-silicone njengento engcono kakhulu yokuklama idivayisi yezokwelapha:

1. Iketanga elikhulu le-oxygen le-silicon linikeza ukuzinza okuhle kakhulu kokushisa.
I-Silicone inokuqina okuhle kakhulu kokushisa, okuvumela imishini ukuthi igcine izakhiwo ezibalulekile ngisho nangemva kokuhlanza. I-Silicone ingahlanzwa ngokuhlanza ngomusi oshisayo osezingeni eliphezulu, ukuhlanza nge-epoxy zane (EtO), noma ngemisebe ye-Y.

2. I-Silicone iyinto engasebenzi kahle.
I-silicone ivame ukungangeni eziwuketshezi zomzimba nemithi, futhi ayinaphunga. Isakhiwo sayo samakhemikhali sihlangabezana nezindinganiso ze-USP Class VI kanye ne-ISO 10993.

3. I-silicone ayinayo i-plasticizer noma ezinye izithako eziphilayo.
i-plasticizer noma ezinye izithasiselo eziphilayo zingaba nomthelela omubi ekulethweni kokukhiqizwa kwemithi, uma izithasiselo zikhona, kungenzeka ukuthi zithuthele emuthini owuketshezi futhi ijeli le-silica alinazo izithasiselo ezifana ne-plasticizer noma izithasiselo eziphilayo.

4. I-silicone iqinile.
I-Silicone inokuqina okuhle kanye nokululama ngemva kokubhoboza ukuze kuncishiswe ukukhathala kwezinto ezibonakalayo. Lezi zakhiwo ezibalulekile zinikeza i-silicone impilo ende yenkonzo, ngisho nangaphansi kokucindezeleka okuguquguqukayo.

5. I-Silicone ine-modulus ephansi.
I-silicone idinga amandla amancane okufaka ukuze kuthuthukiswe ukusebenza kahle kwedivayisi — noma kube lula ukuyihlanganisa uma ihlanganiswa nezinye izingxenye.

6. I-Silicone ingenziwa ibe ubulukhuni obuhlukahlukene.
I-silicone ingabunjwa ngobunzima obuhlukahlukene ukuze ivumelane nezinto eziqinile kakhulu noma ezithambile kakhulu, okwandisa amathuba okuthuthukiswa kwe-ergonomics kanye nenduduzo.

7. I-Silicone inomuzwa omuhle wobuhle bomklamo.
Ama-silicone elastomer amaningi anombala okhanyayo futhi avame ukufakwa umbala kalula.

8. I-Silicone kulula ukuyicubungula.
Ngaphezu kobulukhuni bayo, induduzo kanye nezici zobuhle, i-silicone inikeza izinketho eziningi zokwenza ngokwezifiso. Izinto zokwakha zingasetshenziswa kumadivayisi ahlukahlukene kanye nemiklamo, kusukela kuma-catheter okufakwayo kuya kuma-valve okusika kuya kumamaski okuphefumula. Ezinye izinketho zokwenza ngokwezifiso zifaka phakathi amandla okudonsa, i-coefficient of friction, isikhathi sokupholisa kanye nokwelulwa.

Ukusetshenziswa kwemikhiqizo ye-silicone kumathuluzi ezokwelapha.

Izinto ezithinta isikhumba somuntu:
(1) Imaski yokuphefumula: ikakhulukazi imaski ye-silicone edinga ukugqokwa isikhathi eside.
(2) Ukunakekelwa kwenxeba: Ijeli ye-silicone ilungele isikhumba futhi iyaphefumula, futhi ngeke ibangele ukulimala kwesibili enxebeni. Ngakho-ke, ijeli ye-silicone ye-Magtu iyisinqumo esihle sokufaka i-foam, i-scar paste, njll.
(3) Izibambo zezinsimbi: Izibambo ezithambile nezingasheleli kumele zihlangane nezinsimbi zezokwelapha ezidinga ukubanjwa, njengemimese yokuhlinzwa.

Izinto zokuthintana komzimba womuntu:
Imaski ye-silicone laryngeal: uma ithintana ne-trachea, i-silicone ithambile futhi iqinile ukuqinisekisa ukuthi umgudu womoya ubushelelezi.
Ama-catheter e-silicone: I-silicone isekela ukukhiqizwa kwemizimba yamashubhu aguquguqukayo kanye namabhaluni anamandla aphezulu okudonseka.
Ishubhu lesisu le-Silicone: ubulukhuni obufanele, ishubhu lesisu le-silicone liyisinqumo esihle ezigulini.

Imishini yokuxhumana negazi lomuntu kanye noketshezi lomzimba:
I-catheter yedivayisi yokufaka: njengepayipi lephampu ye-peristaltic yephampu yokufaka, ipayipi langaphandle le-catheter ye-silicone efakiwe.
Izingxenye zezinsimbi zokufaka: njengepulaki yerabha ye-silicone engenasihlanganisi senaliti, isihlungi se-silicone O-ring sesihlungi se-renal dialysis, njll.
Amapulagi epulasitiki namavalvu e-hemostatic kuzo zonke izinhlobo zezinto ezisetshenziswayo zezokwelapha ezithinta uketshezi lwezokwelapha kanye noketshezi lomzimba.
Ngaphezu kwalokho, ijeli ye-silica inezinhlobo eziningi zezicelo, kusukela kuma-contact lens kuya kumishini yokuhlola yezokwelapha egqokwayo, kusukela kwezokwelapha ze-biopharmaceutical kuya ocwaningweni nasekuthuthukisweni kwemithi yokugoma, ijeli ye-silica ingasetshenziswa kabanzi kulo mkhakha.
