Kev lag luam khoom siv kho mob thoob ntiaj teb tau nce qib siab dua rau cov khoom siv raw kev nyab xeeb thiab kev ruaj ntseg hauv 2026, tshwj xeeb tshaj yog rau cov khoom siv kho mob ntev ntev xws li PICC catheters. Tsis zoo li cov khoom siv TPU zoo tib yam, PICC- qib TPU pellets yuav tsum dhau ntau qhov kev sim tshuaj lom neeg thiab lub cev kom hloov mus rau qhov ntev -lub sij hawm venous indwelling scenarios, thiab tau maj mam tsim ib qho kev ywj pheej segmented khoom tus qauv nyob rau hauv siab -kawg kho mob lag luam.
Cov ntaub ntawv soj ntsuam kev lag luam qhia tau hais tias tsim nyog PICC catheter TPU cov ntaub ntawv yuav tsum ua raws li ISO 10993 cov qauv tshuaj ntsuam xyuas kab mob lom neeg thiab USP Class VI daim ntawv pov thawj qib kho mob. Cov ntsuas nruj xws li cell cytotoxicity, tawv nqaij rhiab heev, hemolysis tus nqi thiab residual extractables yuav tsum tau tswj nyob rau hauv ultra- tsawg ranges. Qhov no yog qhov laj thawj tseem ceeb vim li cas dav dav -Lub hom phiaj TPU tsis tuaj yeem hloov kho kho- cov qauv tshwj xeeb hauv cov cuab yeej siv tshuaj vascular.
Hauv kev tshuaj xyuas daim ntawv thov kev tawm tswv yim, cov tshuaj PVC thiab silicone catheters muaj qhov tsis zoo. Cov ntaub ntawv PVC muaj cov yas yas los nag lossis daus, thaum cov raj silicone yog mos dhau lawm thiab ua rau lub raj tawg thaum tso. Nyob rau hauv sib piv, customized polyether -raws li kev kho mob TPU pellets tuav balanced hardness thiab yooj. Lub zog tensile ruaj khov, thiab lub raj lub cev yuav tsis kink lossis deform thaum lub sij hawm ntev - nyob rau hauv. Lub caij no, cov khoom siv tau zoo heev hydrolysis tsis kam, muaj txiaj ntsig zoo kom tsis txhob muaj kev cuam tshuam los ntawm kev sib cuag nrog cov ntshav thiab cov kua hauv lub cev ntev li 3-6 lub hlis ntawm kev siv tshuaj kho mob.
Nrog kev nruj nruj ntawm kev saib xyuas cov cuab yeej kho mob hauv ntau lub teb chaws, cov chaw tsim khoom hauv qab catheter tau maj mam tshem tawm cov khoom tsis yog -tus qauv dav dav thiab tig mus rau cov khoom kho mob ruaj khov - qib TPU cov neeg muag khoom. Raws li cov chaw tsim khoom lag luam tsom mus rau cov khoom siv kho mob tshwj xeeb polymer raw khoom, peb nruj me ntsis tswj cov mis purity, residual monomers thiab volatile tshuaj ntawm PICC-TPU pellets tshwj xeeb. Txhua batch yog nruab nrog ua tiav cov ntaub ntawv soj ntsuam lom neeg thiab cov ntaub ntawv batch traceability, ua tau raws li kev tsim khoom loj thiab kev tso npe ua ntaub ntawv ntawm siab -kawg PICC catheter manufacturers.
