Ha re kopana le lisebelisoa tsa bongaka, litho tsa maiketsetso kapa lisebelisoa tsa ho buoa, hangata re hlokomela hore na li entsoe ka thepa efe. Etsoe, khetho ea rona ea thepa ke ea bohlokoa. Rabara ea silicone ke thepa e sebelisoang haholo lefapheng la bongaka, 'me litšobotsi tsa eona tse ntle tsa biocompatibility li lokela ho hlahlojoa ka botebo. Sengoliloeng sena se tla hlahloba ka botebo biocompatibility ea rabara ea silicone le ts'ebeliso ea eona lefapheng la bongaka.
Rabara ea silicone ke lisebelisoa tse phahameng tsa limolek'hule tse nang le li-silicon bond le carbon bond ka har'a sebopeho sa eona sa lik'hemik'hale, kahoo e nkoa e le lintho tse sa tloaelehang. Lefapheng la bongaka, rabara ea silicone e sebelisoa haholo ho etsa lisebelisoa tse fapaneng tsa bongaka le lisebelisoa tsa bongaka, joalo ka manonyeletso a maiketsetso, li-pacemaker, li-prostheses tsa matsoele, li-catheters le li-ventilator. Le leng la mabaka a mantlha a etsang hore rabara ea silicone e sebelisoe haholo ke biocompatibility ea eona e ntle haholo.
The biocompatibility ea silicone rabara hangata e bolela mofuta oa tšebelisano lipakeng tsa thepa le lisele tsa motho, mali le maro a mang a tlhaho. Har'a tsona, matšoao a tloaelehileng a kenyelletsa cytotoxicity, karabelo ea ho ruruha, karabelo ea 'mele ea ho itšireletsa mafung le thrombosis.
Pele ho tsohle, cytotoxicity ea rabara ea silicone e tlase haholo. Sena se bolela hore ha rabara ea silicone e kopana le lisele tsa motho, e ke ke ea baka liphello tse mpe ho tsona. Ho e-na le hoo, e khona ho sebelisana le liprotheine tse holim'a sele le ho khothalletsa tsosoloso ea lisele le ho lokisoa ka ho li tlama. Phello ena e etsa hore rabara ea silicone e be thepa ea bohlokoa masimong a mangata a biomedical.
Taba ea bobeli, rabara ea silicone le eona ha e bake karabelo e kholo ea ho ruruha. 'Meleng oa motho, karabelo ea ho ruruha ke mokhoa oa ho itšireletsa o qalisoang ha' mele o lemetse kapa o tšoaelitsoe ho sireletsa 'mele ho senya ho eketsehileng. Leha ho le joalo, haeba thepa ka boeona e baka karabelo ea ho ruruha, ha e loketse ho sebelisoa lefapheng la bongaka. Ka lehlohonolo, rabara ea silicone e na le ts'ebetso e tlase haholo ea ho ruruha, ka hona ha e bake kotsi e kholo 'meleng oa motho.
Ntle le cytotoxicity le karabelo ea ho ruruha, rabara ea silicone e boetse e khona ho fokotsa karabelo ea 'mele ea ho itšireletsa mafung. 'Meleng oa motho, sesole sa' mele ke mokhoa o sireletsang 'mele ho likokoana-hloko tse ka ntle le lintho tse ling tse kotsi. Leha ho le joalo, ha lintho tsa maiketsetso li kena ’meleng, tsamaiso ea ’mele ea ho itšireletsa mafung e ka ’na ea li hlokomela e le lintho tse tsoang linaheng tse ling ’me tsa qala karabelo ea ’mele ea ho itšireletsa mafung. Karabelo ena ea 'mele ea ho itšireletsa mafung e ka baka ho ruruha ho sa hlokahaleng le liphello tse ling tse mpe. Ka lehlakoreng le leng, karabelo ea 'mele ea ho itšireletsa mafung ea rabara ea silicone e tlaase haholo, e bolelang hore e ka ba teng' meleng oa motho ka nako e telele ntle le ho baka karabelo leha e le efe ea ho itšireletsa mafung.
Qetellong, rabara ea silicone e boetse e na le thepa ea anti-thrombotic. Thrombosis ke lefu le etsang hore mali a hoama le ho etsa maqeba. Haeba leqeba la mali le robeha ’me le isoa likarolong tse ling, le ka baka lefu la pelo, setorouku le mathata a mang a tebileng a bophelo. Rabara ea silicone e ka thibela thrombosis 'me e ka sebelisoa lisebelisoa tse kang li-valve tsa maiketsetso tsa pelo, ho thibela ka katleho mathata a bophelo bo botle a kang lefu la pelo le stroke.
Ka bokhutšoanyane, biocompatibility ea rabara ea silicone e ntle haholo, e etsang hore e be thepa ea bohlokoa lefapheng la bongaka. Ka lebaka la cytotoxicity e tlase, reactivity e tlase ea ho ruruha, ts'ebetso e tlase ea immunoreactivity le li-anti-thrombotic, rabara ea silicone e ka sebelisoa haholo ho hlahisa litho tsa maiketsetso, lisebelisoa tsa bongaka le lisebelisoa tsa ho buoa, joalo-joalo, ho thusa bakuli ho fumana liphetho tse ntle tsa kalafo le boleng ba kalafo. bophelo.
