Ob xyoos dhau los, ib qho ntawm peb cov neeg koom tes ntev -, lub chaw tsim khoom siv urological nyob rau sab hnub tuaj Asia, ua tiav cov ntaub ntawv hloov kho tshiab rau lawv ob lub J ureteral stents los ntawm kev hloov mus rau peb cov kev kho mob - qib TPU. Lawv qhov kev paub dhau los qhia tias yog vim li cas cov kws kho mob ntau dua tau nqis peev rau hauv siab - lub hom phiaj kev ua tau zoo- ua cov khoom siv polymer.
Ua ntej kev koom tes, lub Hoobkas tso siab rau kev kho mob TPU muaj los ntawm cov neeg muag khoom hauv zos. Thaum lub sij hawm soj ntsuam cov lus tawm tswv yim, lawv tau txais cov lus tsis txaus siab: qee qhov stents tau dhau los ua nruj dhau tom qab ib hlis ntawm kev cog qoob loo, thaum qee cov khoom siv tau pom qhov tsis sib xws tom qab ethylene oxide sterilization. Qhov tsis ruaj khov zoo txwv lawv txoj kev lag luam nthuav dav, tshwj xeeb tshaj yog kev twv nrog cov tsev kho mob ntiag tug thiab cov neeg tuaj txawv teb chaws uas xav tau kev sib koom ua ke nruj.
Tom qab kev sib txuas lus, lawv tau xaiv peb cov qib TPU tshwj xeeb uas tsim los rau ntev -lub sij hawm indwelling ureteral stents. Peb xub muab cov qauv kuaj rau kev kuaj extrusion. Pab pawg R & D tau pom sai sai pom cov kev txhim kho pom tseeb: cov kav dej ua kom zoo dua qub, cov thickness hloov pauv tau txo qis, thiab tsawg dua cov hlab ntsha tawg tau tshwm sim thaum lub sijhawm kev sim ntau lawm. Tom ntej no tuaj simulated tso zis tso zis thiab hluav taws xob sterilization kuaj. Cov ntaub ntawv ntsuam xyuas tau lees tias cov khoom siv kho tshuab tseem nyob ruaj khov thoob plaws lub hom phiaj kev pabcuam.
Thaum pib tsim ntau lawm, lawv cov stent tsis lees paub tiav tau poob qis. Qhov kub thiab txias -adaptive softness coj tus neeg mob lub tswv yim zoo dua. Lawv hloov kho cov ntawv qhia khoom qhia txog cov khoom siv kho mob TPU cov khoom siv txawv teb chaws, uas tau dhau los ua kev lag luam muaj txiaj ntsig zoo thaum sib tham nrog cov neeg muag khoom. Hauv 12 lub hlis, lawv qhov kev txiav txim txawv teb chaws rau ureteral stents loj hlob tsis tu ncua.
Cov ntaub ntawv no qhia tau hais tias muaj tseeb tiag: cov neeg siv kawg thiab cov tsev kho mob nce siab rau cov khoom siv raw zoo ntawm cov khoom siv kho mob pov tseg. Generic polymers yuav txo qis luv luv - cov nqi them, tab sis qhov tsis zoo ntawm kev pheej hmoo ua rau lub npe nrov npe. Lub hom phiaj-tsim tsim kho TPU rau ureteral stents sib npaug kev ua tau zoo, ua tus phooj ywg thiab kev tswj xyuas kev taug qab.
Peb pab neeg txuas ntxiv txhim kho TPU cov qauv kom ua tau raws li cov kev xav tau ntawm kev lag luam hloov zuj zus, suav nrog cov qib sib xws nrog kev tiv thaiv kab mob - hloov kho cov kab mob microbial thiab txhim kho radiopaque versions. Peb zoo siab txais tos cov tuam txhab ureteral stent, tubing extrusion factories thiab cov neeg tsim khoom kho mob thoob ntiaj teb kom ncav cuag cov qauv ntsuas thiab kev sib tham. Txawm hais tias koj npaj cov khoom lag luam tshiab lossis cov khoom siv raw hloov pauv rau cov qauv stent uas twb muaj lawm, peb tuaj yeem muab cov lus pom zoo rau cov khoom siv raws li koj cov khoom siv extrusion, lub hom phiaj stent specifications thiab lub hom phiaj kev lag luam thoob ntiaj teb.
