Tsav los ntawm qhov nrov nrov ntawm kev cuam tshuam kev cuam tshuam tsawg kawg nkaus thiab ntev - kev tswj hwm tus neeg mob hauv lub sijhawm infusion, lub ntiaj teb PICC catheter kev lag luam txuas ntxiv nthuav dav hauv xyoo 2026, ncaj qha tsav cov kev xav tau ntau ntxiv rau siab -purity kho mob TPU pellet raw khoom. Ntau lub tsev kho mob tertiary thiab cov tsev kho mob tshwj xeeb yog qhov tseem ceeb tshaj -Kev ua tau zoo TICC catheters kom txo tau cov teeb meem kho mob xws li venous thrombosis thiab vascular irritation.
Cov ntaub ntawv tshawb fawb txog kev lag luam qhia tau hais tias qhov nkag mus ntawm TPU cov ntaub ntawv hauv nruab nrab thiab siab -kawg PICC catheter cov khoom tau mus txog 65%–75%, dhau los ua cov khoom siv tseem ceeb rau cov khoom siv tshiab - tiam indwelling catheters. Qhov txiaj ntsig tseem ceeb nyob hauv cov khoom siv tswj tau qis - kev sib txhuam ntawm qhov ua tau zoo. Tom qab kev kho hydrophilic txheej txheej, qhov kev sib txhuam coefficient ntawm qhov chaw yog txo qis, uas tuaj yeem txo cov hlab ntsha thiab txhim kho smoothness ntawm catheter insertion.
Sib txawv ntawm cov khoom lag luam zoo tib yam TPU, PICC tshwj xeeb TPU pellets txais siab -purity polyether mis tsis muaj cov khoom siv rov ua dua tshiab thiab muab tub lim impurities. Cov khoom siv tau zoo heev tsawg- kub toughness thiab ruaj khov lub cev muaj zog, thiab yuav tsis nkig, daj los yog tawg thaum lub sij hawm cov pa ethylene oxide sterilization thiab siab - zaus tshuaj tua kab mob. Qhov kev ua kom tsis muaj menyuam ruaj khov no daws qhov teeb meem ntawm kev ua haujlwm tsawg ntawm cov khoom siv tshuaj kho mob polymer tom qab rov ua tshuaj tua kab mob.
Tam sim no, kev lag luam raw khoom siv kho mob tau qhia pom tseeb qhov sib txawv. Tsawg- cov khoom siv dav dav tau ntsib cov nqi sib tw, thaum siab - tus qauv kho mob TPU pellets tsis txaus. Kev cia siab rau kev kho mob paub tab - qib formula system thiab ruaj khov batch ntau lawm muaj peev xwm, peb muaj peev xwm muab tsau -hardness thiab customized hloov TPU pellets rau PICC catheter manufacturers. Cov khoom lag luam ua tau raws li qhov ntev - lub sij hawm indwelling kev nyab xeeb yuav tsum tau ntawm cov chaw kho mob cov cuab yeej, thiab txhawb cov neeg muas zaub 'cov ntaub ntawv sau npe tshuaj ntsuam xyuas thiab ruaj khov loj xa tuaj.
