O le mea na tupu i totonutele lumen paipa faafomaitekinolosi extrusion uasiitiale fa'aogaina o foma'ipaipai se tulaga fou.

I totonu o le alamanuia masini faafomai, o le si'itia aupito itiiti invasivee saeia e mana'omia smallermamasini fa'afoma'i fou.O masini e fa'agaoioi ai a'a toto po'o isi a'ano aano e mana'omia le foma'ipaipafa'atasi ai ma le sa'o maualuga, fa'apalepale fa'amalosi ma galuega fa'aopoopos.E pei oua mamanuina faagaausili atu faigata, o tekinolosi extrusionto gaosia i latouatili lavelave.E leai se masalosaloo letele-lumene paipaextrusiontekinolosio lo'o ta'imua i tekinolosi extrusion.

Tele-lumeneextrusion po'o fa'atasi fa'atasi e mafai ona faauigaina o le extrusion tutusa o le tele o layers o mease gaosiafaagaau faafomai tele-lumen.Tele-lumenee fa'aaoga muamua tekinolosi e fa'aleleia ai le fa'atinoga: tu'ufa'atasia o mea e mafai ona u'uina ma mea e iai nisi uiga fa'atinoga, e pei o le lubricity.O nei fausaga e mafai foi ona faʻaleleia le faʻatinoga ma mafai ona faʻaititia le aofaʻi atoa o le faʻapotopotoga ma tau o meafaitino, faʻafaigofieina masini faʻafomaʻi mo tagata faʻatau;o isi vaega e mafai ona aofia ai le faʻaopoopoina o mea faʻaoga faʻamalosi, pei ole hydrophilic, bioabsorbable poʻo vailaʻau-eluting layers.O tekinolosi ma mea e maua e maua ai oloa faʻapipiʻi tele mo masini faʻafomaʻi ua matua faʻaleleia ma ofoina atu i tagata mamanu le tele o filifiliga mo le optimized tele, meafaitino ma galuega.

O galuega tauave afoma'i PTFE tele-lumen tubingi masini faafomaiaofia ai: itoeing paipafa'afanua e eseese uiga mo fafo ma totonu;fa'atasimea e iai uiga eseese e fatu ai tulaga esepaipauiga;mafaimea aogape 'atulaga lelei;su'einamea faʻapipiʻi i totonu poʻo fafo mo le faʻapipiʻiina e le tagata lava ia ma faigofie faʻapipiʻi o masini faʻafomaʻi lavelave.

Le faʻagasologa o le tele-lumen tubes mana'omia le au tekinisia e fa'apipi'i fa'atasi le tele o mea fa'apipi'i ma mea faigaluega i lalo.Faatasi ai ma lenei auala le lelei, e foliga mai o le extruders eseese o le a i ai uma i le vaalele e tasi, e mafua ai le umi o auala tafe, faateleina le mamafa o le extruder ma faateleina le taimi o meafaitino.I lalo o ia auala fa'agaioiga,le manaomiapaipae le fetaui fua fa'atatau o le vaega sili ona lelei o le extruder, lea e mafai ona i'u aimaualuga tele pe maualalofa'avili vave, ma isi mea gaosia paipafa'atasi ai ma mea fa'ainisinia leaga.

Fa'aonaponei lumen telepaipae sili atu le fa'apipi'iina o meafaigaluega fa'apipi'igaosigalaina faʻatasi ma se faʻaoga faʻapitoa e tasi e mataʻituina, pulea ma faʻamaumau le faʻaogaina atoa o le faiga i le taimi moni.Extruders mo vaega polymer ta'itasi ua filifilia e tu'uina atu ai le mana'omia o le saosaoa o gaosiga e le fa'afefe ai mea fa'ainisinia o mea.O loʻo faʻatulagaina e faʻaitiitia ai le taimi e nofo ai, ma e masani lava ona tasi pe sili atu extruders e mafai ona faʻapipiʻi i luga pe i le 45 ° angle.E masani lava, tasi pe sili atu extruders i se tele-lumen faiga o le a micro-extruders maitiiti ifogaluega faatinoof 50 kalama i le itula, faʻatagainaanvaega ta'itasi ia na'o ni nai microns mafiafia.E fa'aogaina e le au fai mea fa'apipi'i fa'ata'ita'i fa'afoliga fou e fa'amautinoa ai o pelleti palasitika masani e feoa'i lelei i le vaega fafaga o le fa'apalapala e aunoa ma le leiloa o le mautu.

O fa'amoemoega o tagata fa'atau o lo'o fa'ateleina le fa'aogaina o ia faiga fa'afuainumera fa'agasologa fa'atonu ma fa'ateleina mana'oga o oloa mai lala sooupu fa'atonutonu.Ae ui i lea, sa'o i-laina fua othinwumama'oa'ogatubingo lo'o tumau pea se lu'itau tele mo tagata gaosi masini fa'afoma'i.

O lo'o i ai lava ni nai mea fa'agata e mafai ona mauafa'aaogainae mamanuina paipa tele-lumen.O mea e masani ona faʻaaogaina o mea ia e masani ona faʻaaogaina e fai ai paipa faʻafomaʻi, e pei o le polyamide (PA), thermoplastic elastomer (TPE), polyurethane (PU), polyvinyl chloride (PVC), ma le polyolefin (PE).O mea nei e mafai ona fa'avasegaina e aofia ai vaila'au-eluting vaega, mea leitio, fa'atumu, ma/po'o lanu.Ae ui i lea, e tatau i le tagata mamanu ona mafaufau i le vevela o le gaosiga, uiga tafe ma le liusuavai o mea.

Tele-lumenpaipatekinolosi extrusion e matua talafeagai mo extruding tala po o le malositaugatamea e iai galuega fa'apitoa aua e mafai ai ona fa'atulaga lelei le tu'uina o nei mea i luga o lepaipa faafomai. A cfaataitaiga omonio le: tuumea e fa'afefe ai fualaau fa'asaina i le pito i fafo o lepaipapetu'umea e sili ona lubricated i luga o le apa totonu o lepaipa.E lē gata i lea,tele lumen paipa faafomaiuatau lelei ona o mea manifinifimafai ona tuui nofoaga sili ona aoga.
