Kev tawg hauvmulti lumen kho mob tubingextrusion tshuab muajnce qibdaim ntawv thov kev kho mobcov rajmus rau theem tshiab.

Hauv kev lag luam khoom siv kho mob, qhov tsawg kawg nkaus invasive surgery rends xav tau smallerthiabcov cuab yeej kho mob tshiab dua tshiab.Cov khoom siv uas ua rau cov hlab ntsha lossis lwm cov ntaub so ntswg xav tau kev kho mobcov rajnrog siab dua precision, nruj tolerances thiab ntxiv muaj nuj nqis.Raws licov raj yog tsimntau complex, lub extrusion technologiesto tsim lawvua nyuaj.Tsis muaj kev ntseeg li ntawdtusntau-lumen cevextrusiontshuabyog nyob rau hauv lub forefront ntawm extrusion technology.

Ntau-lumenextrusion los yog co-extrusion tuaj yeem txhais tau tias yog ib txhij extrusion ntawm ntau txheej ntawm cov khoomstsim tawmmulti-lumen kho mob raj.Ntau-lumenthev naus laus zis feem ntau yog siv los txhim kho kev ua haujlwm: sib txuas cov ntaub ntawv weldable nrog cov ntaub ntawv uas muaj qee yam kev ua tau zoo, xws li lubricity.Cov qauv no tuaj yeem txhim kho kev ua tau zoo thiab muaj peev xwm txo tau tag nrho cov khoom sib dhos thiab cov khoom siv, ua rau cov khoom siv kho mob tau txais txiaj ntsig zoo rau cov neeg siv khoom;Lwm cov nta yuav suav nrog qhov sib ntxiv ntawm cov khoom siv hluav taws xob, xws li hydrophilic, bioabsorbable lossis cov tshuaj tiv thaiv cov khaubncaws sab nraud povtseg.Cov thev naus laus zis thiab cov ntaub ntawv muaj los tsim cov khoom siv ntau yam rau cov khoom siv kho mob tau txhim kho zoo heev thiab muab cov qauv tsim ntau yam kev xaiv rau optimized qhov loj, khoom siv thiab kev ua haujlwm.

Cov haujlwm ntawmKev kho mob PTFE multi-lumen tubinghauv cov khoom siv kho mobmuaj xws li: crovhauv cevnto nrog cov yam ntxwv sib txawv rau sab nrauv thiab sab hauv;ua kecov ntaub ntawv nrog cov yam ntxwv sib txawv los tsim tshwj xeebcevyam ntxwv;ua haujlwmcov khoom sivuazoo nyob;qhov chawbondable cov ntaub ntawv nyob rau hauv los yog externally rau nws tus kheej-assembly thiab yooj yim los ua ke ntawm complex cov cuab yeej kho mob.

Kev ua ntawm multi-lumen tubes xav tau cov kws tshaj lij los ua ke ntau yam ntawm extruders thiab cov khoom siv hauv qab.Nrog rau txoj kev tsis zoo no, nws zoo li ntau yam extruders yuav tag nrho nyob rau hauv tib lub dav hlau, uas ua rau txoj kev khiav ntev dua, nce extrusion siab thiab nce cov khoom siv sijhawm.Nyob rau hauv xws li kev ua,qhov xav taucevtxheej ratios tsis phim lub optimum tso zis ntawm lub extruder, uas yuav ua tau nyob rau hauvsiab lossis qisntsia hlau ceev, thiab ntxiv tsim cov rajnrog cov khoom siv tsis zoo.

Niaj hnub nimno multi-lumencevcov khoom siv extrusion ua ntau dua yuav ua kom muaj kev sib koom ua kentau lawmkab nrog ib tus neeg teb xov tooj interface uas saib xyuas, tswj thiab sau tag nrho cov txheej txheem extrusion hauv lub sijhawm.Extruders rau txhua txheej txheej polymer raug xaiv los muab qhov xav tau ntau yam ntawm cov zis nrawm uas tsis cuam tshuam cov khoom siv ntawm cov khoom siv.Lawv tau muab tso rau kom txo cov khoom siv nyob hauv lub sijhawm, thiab feem ntau yog ib lossis ntau qhov extruders tuaj yeem ntsia tau ntsug lossis ntawm lub kaum sab xis 45 °.Feem ntau, ib los yog ntau tshaj extruders nyob rau hauv ib tug multi-lumen system yuav micro-extruders nrogyam tsawg kawg nkaustso zisof 50 grams tauj ib teev, tso caiantus txheej txheem yuav tsum yog ob peb microns tuab.Cov neeg tsim khoom ntawm cov micro-extruders siv cov txheej txheem extruder tsim los xyuas kom meej tias cov qauv yas pellets taug kev zoo los ntawm cov khoom noj ntawm lub extruder yam tsis muaj kev ruaj ntseg.

Kev cia siab ntawm cov neeg siv khoom yog tsav kev siv loj ntawm cov txheej txheem tswj xyuas cov txheej txheem thiab ua kom cov khoom xav tau los ntawm cov koom haum tswj hwm.Txawm li cas los xij, qhov tseeb hauv kab ntsuas ntawmthinwtag nrhomedicaltua ubingtseem yog ib qho kev sib tw loj heev rau cov tuam txhab kho mob.

Tseem muaj ob peb yam khoom siv thermoplastic uas tuaj yeem ua tausivlos tsim multi-lumen raj.Cov ntaub ntawv siv ntau tshaj plaws yog cov uas ib txwm siv los ua cov raj kho mob, xws li polyamide (PA), thermoplastic elastomer (TPE), polyurethane (PU), polyvinyl chloride (PVC), thiab polyolefin (PE).Cov ntaub ntawv no tuaj yeem hloov kho kom suav nrog cov tshuaj siv tshuaj, cov khoom siv hluav taws xob, cov khoom ntim, thiab / lossis xim.Txawm li cas los xij, tus tsim qauv yuav tsum xav txog qhov ua haujlwm kub, cov yam ntxwv ntws thiab yaj viscosity ntawm cov khoom.

Multi-lumencevextrusion tshuab yog tshwj xeeb tshaj yog haum rau extruding tshiab los yog nquagkimcov ntaub ntawv uas muaj cov haujlwm tshwj xeeb vim nws tso cai rau kev tsim kom zoo ntawm kev tso kawm ntawm cov ntaub ntawv no ntawm lublub cev kho mob. A comm pivyog :latshuaj-eluting cov ntaub ntawv nyob rau txheej txheej ntawm lubcevlos yogtsoheev lubricated cov ntaub ntawv nyob rau hauv lub puab txheej ntawm lubcev.Tsis tas li ntawd,multi lumen kho mob tubingmuajtus nqi zoo vim cov txheej nyias nyiastuaj yeem muab tso raunyob rau hauv qhov chaw zoo tshaj plaws.
