PTFE yubushyuhe bwo hejuru ikoreshwa mubice bitatu byubuvuzi: kurinda ibikoresho byo kuboneza urubyaro (tray autoclave tray, gupakira ubushyuhe bwa kashe), kuvura ibikoresho byo hejuru (gutwika-friction nkeya, kubika amashanyarazi), hamwe nibikoresho byatewe (graft vasculaire, suture). Biocompatibilité igenzurwa hakoreshejwe ISO 10993, naho FDA 21 CFR 177.1550 ishyiraho umutekano wibikoresho fatizo.

PTFE yubushyuhe bwo hejuru ifite imbaraga zo kurwanya imirasire ya ionizing. Kuri 1 kGy gamma yerekanwe gusa, imbaraga zingana ziragabanuka kugeza ~ 25% byumwimerere. Irakwiriye gusa kubidukikije bikabije (ibiryo / sterisizione yubuvuzi <10 kGy). Ku nganda za kirimbuzi cyangwa icyogajuru, koresha polyimide cyangwa PEEK aho.

PTFE yubushyuhe bwo hejuru busaba ububiko bukwiye kugirango bugumane, bworoshye, kandi burekure imikorere. Ibisabwa byingenzi birimo kugenzura ubushyuhe (10-30 ° C), ubuhehere buri munsi ya 60%, kwirinda urumuri, kwigunga imiti, gushyira vertical, no guhumeka. Kurikiza imicungire ya FIFO kandi ugenzure buri gihe.

Iyi ngingo isobanura uburyo bwo kwirinda kwanduza no kwangiza imikorere kuruhande rudafatanye na kaseti ya PTFE yubushyuhe bwo hejuru mugihe cyo gutwikira. Ingamba zingenzi zirimo kugenzura inkomoko (kuvura neza neza), kwigunga kumubiri (firime ikingira, imizingo idafite inkoni, gukama zone), hamwe no gucunga neza inzira.

Nkumushinga wumwimerere wa kaseti ya PTFE yubushyuhe bwo hejuru, Jiangsu Aokai Ibikoresho bishya rero birasobanura ingaruka zuburyo bwo gukonjesha nigipimo cyo gukonjesha kumikorere ya kaseti ya PTFE yakize.I. Ibyingenzi bya Crystallisation ya PTFE Ibiranga no gukonjesha igipimo cyo gukonjesha PTFE su

Jiangsu Aokai Ibikoresho bishya, inkomoko yabigize umwuga ikora PTFE yubushyuhe bwo hejuru, isangira ubushishozi kubwawe.PTFE (Teflon) kaseti yubushyuhe bwo hejuru irashobora gukoreshwa ubudahwema mubushyuhe bwa -196 ℃ kugeza 260 ℃. Mubisabwa byinshi, imipaka irwanya ubushyuhe
