isifinyezo
I-PTFE (i-polytetrafluoroethylene)-lined tube isiba into eyinhloko yama-catheter interventional interventional ngenxa yokuthambisa kwayo okuhle kakhulu, udonga oluncane, ukuguquguquka okuqinile namandla aphezulu okudonsa. I-Maitong Intelligent Manufacturing™Ine-coating ye-dip ethuthukisiwe, i-extrusion yamahhala kanye nezinqubo ze-mandrel extrusion, ngaleyo ndlela iphusha ukusebenza kwamashubhu anemigqa ye-PTFE ezindaweni eziphakeme futhi inikeze amathuba angenamkhawulo womklamo nokusebenzisa ama-catheter angenele. Ngenxa yesistimu yokulawula ikhwalithi eqinile, i-Maitong Intelligent Manufacturing™Ukuzinza komkhiqizo nakho kuye kwaqashelwa ngazwi linye ngamakhasimende.
umbhalo
Uma kuqhathaniswa nama-catheter okungenelela emithanjeni esikhathini esidlule, ukuklanywa kwemikhiqizo ye-catheter yesimanje sekuye kwaba yinkimbinkimbi, ehlanganisa izingxenye ezinembayo njengamashubhu olayini, izendlalelo zokunamathela, izendlalelo ezilukiweyo, nezinto zangaphandle. Ukwenza udonga lwe-catheter lube mncane futhi ububanzi bangaphakathi bube bukhudlwana kuwumgomo abakhiqizi be-catheter abangenelayo abaqhubeka nokuwulandela. I-PTFE (i-polytetrafluoroethylene) ishubhu elifakwe umugqa, elinokugcoba okuhle kakhulu, udonga oluncane, ukuguquguquka okuqinile namandla aqinile, isetshenziswa kabanzi kuma-microcatheter, ama-catheter aphakathi, ama-suction catheter, ama-guide catheter, ama-catheter asekelayo, njll. Imishini yezokwelapha njengama-catheter aguquguqukayo kanye ne-stent. amashethi okuzivikela.
Kodwa-ke, ukufeza ibhalansi phakathi kobukhulu, ukuguquguquka kanye namandla we-PTFE (polytetrafluoroethylene) amapayipi afakwe umugqa kuyinselele ebalulekile ekuthuthukisweni komkhiqizo kanye nenqubo yokucubungula, okuhlanganisa ukubunjwa kwesakhiwo esiyinkimbinkimbi, ukucubungula izinto ezibonakalayo, ukuphathwa kwezinqubo eziningi, i-extrusion Kukhona ubunzima obuningi obunjalo. njengokulawula okunembile kwenqubo nokukhethwa kwezindlela zokubumba.
Ngokuqhubeka nokusungula izinto ezintsha zobuchwepheshe kanye nokwenza kahle kwenqubo, i-Maitong Intelligent Manufacturing™ izibophezele ekwakheni uchungechunge oluningi lwamashubhu anemigqa ye-PTFE asebenza kahle kakhulu ukuze ahlangabezane nesidingo esikhulayo sama-catheter asebenza kahle kakhulu embonini yezokwelapha.
Inqubo ye-Dip coating (ukusakaza ifilimu):
Ukuhlakazwa okugxilile kwe-PTFE kuhlanganiswe ngokulinganayo ocingweni lwensimbi ewumgogodla futhi i-sintered futhi iqiniswe ukuze yakhe ukunamathela okufanayo, bese intambo yensimbi yensimbi isuswa kancane kancane ukuze kutholwe ipayipi le-PTFE elinokuguquguquka okuhle kakhulu.
Inqubo ye-extrusion yamahhala:
Ngemva kokuxuba i-PTFE powder nama-solvents organic kanye nezinto zokugcoba ukuze wenze i-preform, yenziwe ibe yisimo se-tube ngosizo lwe-extruder futhi ifakwe i-sintered ukwenza udonga lwe-tube lube mncane futhi lufane, futhi isakhiwo sokusanhlamvu sithuthukisiwe, ngaleyo ndlela sinikeze ithubhu ephakeme. amandla e-axial nokuqina.
Inqubo ye-Extrusion nge-mandrel:
Ukuhlanganisa izinzuzo ze-cast ifilimu, i-mandrel isetshenziselwa ukusiza ukubunjwa kwe-extrusion ukuze kuqinisekiswe ukufana nokuguquguquka kodonga lwamapayipi olwelwesi ngenkathi ithuthukisa kakhulu amandla ayo. Ngaphezu kwalokho, le nqubo iqeda isidingo sokufaka i-mandrel futhi, igcina izakhiwo zokunamathisela endaweni yepayipi, ifaneleka ukucubungula okuqhubekayo kwe-braiding, futhi ithuthukise kakhulu ukusebenza kahle kokukhiqiza.
Ukusebenza komkhiqizo ngaphansi kwezinqubo ezahlukene:
Ukuhlolwa kwedatha kubonisa ukuthi i-Maitong Intelligent Manufacturing™ iphushele ukusebenza kwamapayipi analayini we-PTFE kwaba phezulu, futhi ukusebenza komkhiqizo kufinyelele noma kweqe izinga elivamile emakethe.
Ukujiya kodonga oluncane kakhulu nokufana
Ugqinsi oluncane kakhulu lwamashubhu anemigqa ye-PTFE akhiqizwa inqubo ye-extrusion yamahhala angafinyelela amayintshi angu-0.00075 (cishe ama-microns angu-19), okuthuthukisa ukuguquguquka nokucaca ngenkathi kunciphisa ububanzi be-catheter nokunciphisa ukulimala kwezicubu.
Amandla okuqina aphezulu
Amapayipi anemigqa ye-PTFE ye-Maitong Intelligent Manufacturing™ agcina izindonga ezibushelelezi, ezinhle, ezincanyana kuyilapho enamandla aqinile aqinile, ngaleyo ndlela athuthukise ukuqina.
Ukulawula ukubekezelelana okunembile
Ukusebenzisa i-mandrel (i-silver-plated copper wire) ubuchwepheshe be-extrusion, ububanzi obuqinile bangaphakathi kanye nokulawula ukubekezelela ukushuba kodonga kufinyelelwa, ukuhlinzeka ngokusekela okuthembekile kwama-catheter angenele.
Ukuphathwa kwekhwalithi
I-Maitong Intelligent Manufacturing™ yakhe indawo yokusebenzela ehlanzekile ye-Class 10,000 ngokuhambisana ngokuqinile nesistimu ye-ISO13485 Kusukela ekuphakeleni kuya ekupakisheni, yonke into iqedwa ku-workshop ehlanzekile ye-Class 10,000 ukuze kuqinisekiswe ukuthi imikhiqizo ihlangabezana nezidingo zebhayoloji zemishini yezokwelapha. Ngesikhathi esifanayo, ifakwe imishini yokukhiqiza ethuthukisiwe, amathuluzi okulinganisa anembile, kanye nezindlela eziqinile zokuhlola nezindlela zokuhlola ukuqinisekisa ukuthi ikhwalithi yomkhiqizo ihlangabezana nezidingo zemishini yezokwelapha.
Isikhathi esiholayo
I-Maitong Manufacturing™ ihola umhlaba ngesikhathi sokuhola, ngemikhiqizo ejwayelekile ilethwa phakathi kwamaviki angu-2 nosayizi abenziwe ngokwezifiso phakathi kwamaviki angu-4.
