Biocompatibilité ya silicone rubber

Iyo duhuye nibikoresho byubuvuzi, ingingo zubukorikori cyangwa ibikoresho byo kubaga, dukunze kubona ibikoresho bikozwe. Nyuma ya byose, guhitamo ibikoresho ni ngombwa. Rubber ya silicone ni ibikoresho bikoreshwa cyane mubuvuzi, kandi nibyiza biranga biocompatibilité bikwiye gushishoza byimbitse. Iyi ngingo izasesengura byimbitse biocompatibilité ya silicone reberi no kuyikoresha mubuvuzi.

Rubber ya silicone ni ibintu byinshi bya molekuline bifite umubiri wa silikoni hamwe na karubone mu miterere y’imiti, bityo bifatwa nkibintu kama kama. Mu rwego rw'ubuvuzi, reberi ya silicone ikoreshwa cyane mu gukora ibikoresho bitandukanye by'ubuvuzi n'ibikoresho by'ubuvuzi, nk'ingingo zihimbano, pacemakers, prothèse y'ibere, catheters na ventilator. Imwe mumpamvu nyamukuru zituma reberi ya silicone ikoreshwa cyane ni biocompatibilité nziza cyane.

Ubuzima bwa biocompatibilité ya reberi ya silicone mubisanzwe bivuga imiterere yimikoranire hagati yumubiri nu ngingo zabantu, amaraso nandi mazi y’ibinyabuzima. Muri byo, ibipimo bikunze kugaragara harimo cytotoxicity, reaction inflammatory, reaction immunite na trombose.

Mbere ya byose, cytotoxicity ya silicone reberi iri hasi cyane. Ibi bivuze ko iyo reberi ya silicone ihuye ningirabuzimafatizo zabantu, ntabwo bizatera ingaruka mbi kuri bo. Ahubwo, irashobora gukorana na poroteyine zo hejuru zingirabuzimafatizo no guteza imbere ingirabuzima fatizo no gusana ubihuza. Ingaruka ituma silicone reberi ari ikintu cyingenzi mubice byinshi byubuvuzi.

Icya kabiri, reberi ya silicone nayo ntabwo itera igisubizo gikomeye. Mu mubiri w'umuntu, igisubizo cyo gutwika ni uburyo bwo kwikingira butangirwa igihe umubiri wakomeretse cyangwa wanduye kugirango urinde umubiri kwangirika. Ariko, niba ibikoresho ubwabyo bitera igisubizo kibabaza, ntibikwiriye gukoreshwa mubuvuzi. Kubwamahirwe, reberi ya silicone ifite reaction nkeya cyane kuburyo idatera ingaruka mbi kumubiri wumuntu.

Usibye cytotoxicity hamwe nigisubizo cyo gutwika, reberi ya silicone irashobora kandi kugabanya ubudahangarwa bw'umubiri. Mu mubiri w'umuntu, sisitemu yubudahangarwa nuburyo bukingira umubiri indwara ziterwa na virusi ndetse nibindi bintu byangiza. Ariko, mugihe ibikoresho byubukorikori byinjiye mumubiri, sisitemu yumubiri irashobora kubamenya nkibintu byamahanga kandi bigatangira igisubizo cyumubiri. Iki gisubizo cyumudugudu gishobora gutera uburibwe budakenewe nizindi ngaruka mbi. Ibinyuranye, ubudahangarwa bw'umubiri wa silicone reberi ni muke cyane, bivuze ko ishobora kubaho mumubiri wumuntu igihe kirekire idateye igisubizo cyumubiri.

Hanyuma, silicone reberi nayo ifite anti-trombotic. Thrombose ni indwara itera amaraso guterana no gukora ibibyimba. Niba amaraso yamenetse akajyanwa mubindi bice, birashobora gutera indwara z'umutima, ubwonko, nibindi bibazo bikomeye byubuzima. Rubber ya silicone irashobora kwirinda trombose kandi irashobora gukoreshwa mubikoresho nka valve yumutima wubukorikori, bikarinda neza ibibazo byubuzima nkindwara z'umutima na stroke.

Muri make, biocompatibilité ya rubber ya silicone ni nziza cyane, bigatuma iba ibikoresho byingenzi mubuvuzi. Bitewe na cytotoxicitike nkeya, reaction nkeya yumuriro, immunoreactivite nkeya hamwe na anti-trombotic, reberi ya silicone irashobora gukoreshwa cyane mugukora ingingo zubukorikori, ibikoresho byubuvuzi nibikoresho byo kubaga, nibindi, kugirango bifashe abarwayi kubona ibisubizo byiza byubuvuzi hamwe nubwiza bwa ubuzima.
