Patinosangana nemichina yekurapa, nhengo dzekugadzira kana zvinhu zvekuvhiya, tinowanzoona kuti ndezvipi zvinhu zvavanogadzirwa nazvo. Mushure mezvose, sarudzo yedu yemidziyo yakakosha. Silicone rabha chinhu chinoshandiswa zvakanyanya munharaunda yekurapa, uye yakanakisa biocompatibility maitiro akakodzera kuongororwa zvakadzama. Ichi chinyorwa chichaongorora zvakadzama biocompatibility yesilicone rabha uye mashandisirwo ayo munharaunda yekurapa.
Silicone rabha ndeyepamusoro-molecular organic zvinhu zvine silicon zvisungo uye kabhoni mabhondi muchimiro chayo chemakemikari, saka inoonekwa seinorganic-organic zvinhu. Muchikamu chekurapa, silicone rabha inoshandiswa zvakanyanya kugadzira michina yekurapa yakasiyana-siyana uye zvinhu zvekurapa, senge majoini ekugadzira, pacemaker, mazamu prostheses, catheter uye mafevha. Chimwe chezvikonzero chikuru nei silicone rabha ichishandiswa zvakanyanya ndeye yakanakisa biocompatibility.
Iyo biocompatibility yesilicone rubber kazhinji inoreva hunhu hwekudyidzana pakati pezvinhu uye matishu emunhu, ropa uye mamwe emvura zvipenyu. Pakati pavo, zviratidzo zvinowanzozivikanwa zvinosanganisira cytotoxicity, kuputika kwechirwere, mhinduro yekudzivirira muviri uye thrombosis.
Chekutanga pane zvese, iyo cytotoxicity yesilicone rubber yakaderera kwazvo. Izvi zvinoreva kuti kana silicone rabha ikasangana nemasero emunhu, haizokonzeri chero zvakaipa pavari. Pane kudaro, inokwanisa kupindirana nesero pamusoro pemapuroteni uye kukurudzira kuvandudzwa kwetishu uye kugadzirisa nekusunga kwavari. Izvi zvinoita kuti silicone rabha ive chinhu chakakosha mune dzakawanda biomedical minda.
Kechipiri, silicone rabha zvakare haikonzere mhinduro yakakosha yekuzvimba. Mumuviri wemunhu, mhinduro yekuzvimba inzira yekuzvidzivirira iyo inotangwa kana muviri uchinge wakuvadzwa kana kutapukirwa kuchengetedza muviri kubva pakumwe kukuvara. Zvisinei, kana iyo pachayo inokonzera mhinduro yekuputika, haina kukodzera kushandiswa mune zvekurapa. Neraki, silicone rabha ine yakanyanya kuderera yekuzvimba reactivity uye saka haikonzere kukuvadza kwakanyanya kumuviri wemunhu.
Pamusoro pe cytotoxicity uye mhinduro yekuzvimba, silicone rabha inokwanisa zvakare kuderedza immune system. Mumuviri wemunhu, immune system inzira inodzivirira muviri kubva kune hutachiona hwekunze uye zvimwe zvinokuvadza. Nekudaro, kana zvinhu zvekugadzira zvapinda mumuviri, immune system inogona kuzviziva sezvinhu zvekunze uye kutanga mhinduro yekudzivirira. Iyi mhinduro yekudzivirira muviri inogona kukonzera kuzvimba kusingakoshi uye zvimwe zvakaipa. Kusiyana neizvi, maitiro ekudzivirira e-silicone rubber akadzika kwazvo, zvinoreva kuti anogona kuvapo mumuviri wemunhu kwenguva yakareba pasina kukonzera chero maitiro ekudzivirira.
Pakupedzisira, silicone rubber inewo anti-thrombotic properties. Thrombosis chirwere chinokonzera ropa kugwamba uye kuita magwamba. Kana ropa rakagwamba robva raendeswa kune dzimwe nzvimbo, rinogona kukonzera chirwere chemwoyo, sitiroko, uye mamwe matambudziko akakomba ehutano. Silicone rabha inogona kudzivirira thrombosis uye inogona kushandiswa mumidziyo yakadai seyekugadzira moyo mavharuvhu, zvinobudirira kudzivirira matambudziko ehutano akadai sechirwere chemoyo uye sitiroko.
Muchidimbu, iyo biocompatibility yesilicone rubber yakanakisa, izvo zvinoita kuti ive chinhu chakakosha mundima yekurapa. Nekuda kweiyo yakaderera cytotoxicity, yakaderera kuzvimba reactivity, yakaderera immunoreactivity uye anti-thrombotic hunhu, silicone rabha inogona kushandiswa zvakanyanya mukugadzira nhengo dzekugadzira, michina yekurapa uye yekuvhiya, nezvimwewo, kubatsira varwere kuwana zvirinani kurapwa uye mhando ye hupenyu.
