Njengoba imboni yezokwelapha iqhubeka ikhula, imishini yezokwelapha kanye nemishini iya ngokuya ithuthuke kakhulu ukuphatha amakhemikhali anonya, izidakamizwa kanye namazinga okushisa.Ukukhetha uphawu olulungile lwezinhlelo zokusebenza zezokwelapha kubalulekile ekusebenzeni kahle kwedivayisi.
Izigxivizo zezokwelapha zisetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa amaphampu ezokwelapha, izingxenye ze-IV, amadivaysi okuphakelayo nezinto zokufakelwa.Inhloso yezimpawu zezokwelapha ukuvikela kokubili abantu kanye nemishini ekuvuzeni okuyingozi.Zisetshenziswa lapho uketshezi noma amagesi empontshwa, ekhanywa, edluliswa, equkethwe noma ekhishwa.
Kunezici eziningi okufanele uzikhumbule lapho ukhetha uphawu olufanele lwedivayisi yezokwelapha.Nazi ezinye zezinto eziphezulu okufanele uzicabangele lapho wenza isinqumo.
Khetha impahla ye-elastomer efanele.
Ukuze ukhethe uphawu olufanele, udinga ukuqonda kuqala isicelo esiseduze.Kufanele ucabangele ukuthintana okungase kube khona, izinga lokushisa, ukunyakaza, ingcindezi nokuthi uphawu ludinga ukuhlala isikhathi esingakanani.
Izimpawu zezokwelapha kufanele zibonise ukumelana namakhemikhali anokhahlo, anobuthi.Kungase kube nezidingo ezithile zekhwalithi zempahla ye-elastomer yophawu.Ukuze umelane nokuqinisekisa ukumelana namakhemikhali, kubalulekile ukuthi uphawu lwenziwe ngama-elastomers asebenza kahle kakhulu kanye nekhwalithi.I-Apple Rubber isebenzisa i-Liquid Silicone Rubber, i-Viton® Fluoroelastomer ne-Ethelyne-Propylene.Lawa ma-elastomer athuthukise ukumelana namakhemikhali, ukumelana nokushisa okuhle kakhulu kanye nokungena kancane kwegesi.
Qaphela i-biocompatibility.
Imishini yezokwelapha ayihlangani ngaso sonke isikhathi nezicubu eziphilayo.Kodwa-ke, lapho amathuluzi nezimpawu zithinta izicubu zomuntu nezinye izinto ezibalulekile njengoketshezi lomzimba, izidakamizwa noma uketshezi lwezokwelapha, kubalulekile ukuqaphela ukuhambisana kwe-biocompatibility kwenhlanganisela yokuvala.
I-Biocompatibility isho ukuthi izakhiwo zezinto ezisetshenziswayo ziyahambisana ngokwebhayoloji futhi azinikezi ukusabela noma impendulo kusicubu esiphilayo.Ukuqinisekisa ukuthi akukho ukusabela okuzokwenzeka ngesikhathi sohlelo lwezokwelapha, kubalulekile ukuhlola ukuhambisana kwe-biocompatibility yophawu bese ukhetha into esekelwe ohlotsheni lwesicelo kanye nomsebenzi.
Ezinye izinto zinokungcola.
Kuhlale kubalulekile ukucabangela ukungcola kwempahla yokuvala.Ngokuhamba kwesikhathi, ukungcola kungaphuma ocingweni nge-toxic noma carcinogenic matter.Ezisetshenziswa zezokwelapha lapho amathuluzi nezimpawu zithintana ngqo nezicubu zomuntu, kwesinye isikhathi zize zifakwe, kubaluleke kakhulu ukuqaphela ubuthi obungaba khona bento.Ngalesi sizathu, onjiniyela kufanele bakhethe into yokuvala enokungcola okuncane noma okungenakho.
Ngaphansi kokukhanya okufanayo, kubalulekile ukuqaphela ukuthi impahla kufanele ifakwe inzalo.Ngezinhlelo ezibandakanya ukuthintana nezicubu eziphilayo, yonke idivayisi yezokwelapha kufanele ibe yinyumba ukuvimbela ukutheleleka.
Ingabe ufuna ukukhuluma kabanzi mayelana nezimpawu zezokwelapha?
