Txheej txheem cej luam:
Polytetrafluoroethylene (PTFE) liners yog siv dav hauv cov khoom siv kho mob vim lawv tsis tshua muaj kev sib txhuam, tshuaj lom neeg, thiab biocompatibility. PTFE liners muab cov npoo sab hauv du rau cov catheters, guidewires, thiab lwm yam kev cuam tshuam cov cuab yeej, ua kom cov cuab yeej ua tau zoo dua qub, yooj yim ntawm kev taw qhia, thiab kev nyab xeeb ntawm tus neeg mob.
Cov ntawv thov tseem ceeb:
- Balloon Catheters: Txo kev sib txhuam ntawm balloon thiab guidewire rau kev xa khoom zoo.
- Microcatheters thiab Guidewires: Ua kom lub zog sib npaug thiab sib kis tau zoo.
- Kev xa tshuaj: pab tswj cov kua dej ntws thiab xa tawm meej.
- Cov cuab yeej Endoscopic thiab Minimally Invasive: Txo kev tiv thaiv kom zoo dua maneuverability.
- Multi- Lumen Catheters: Muab cov kab sib luag, tshuaj lom neeg tsis zoo rau ntau cov kua lossis cov khoom siv.
Qhov tseem ceeb Performance Parameters:
1. Inner Diameter (ID) thiab Outer Diameter (OD): Qhov tseeb qhov ntev yog qhov tseem ceeb rau kev siv khoom sib xws.
2. Phab ntsa Thickness: cuam tshuam yooj, pushability, thiab tawg lub zog.
3. Nto Smoothness: Txiav txim siab sib txhuam coefficient; smoother nto txo qhov tsis kam thiab txhim kho navigation.
4. Mechanical Strength: Tensile thiab elongation zog los tiv thaiv cov cuab yeej siv.
5. Tshuaj thiab Thermal Stability: PTFE yuav tsum tiv thaiv kom tsis muaj menyuam cov txheej txheem (autoclave, ETO) thiab tiv tauj nrog cov tshuaj lossis cov kua dej hauv lub cev.
6. Lubrication thiab Coatings: xaiv hydrophilic lossis lubrication txheej tuaj yeem txhim kho cov cuab yeej ua haujlwm.
7. Dimensional kam rau ua: High precision kom zoo sib xws nyob rau hauv ntau lawm batch.
Supplier Selection Considerations:
- Kev Paub Txog Kev Kho Mob-Qib PTFE: Tus neeg muag khoom yuav tsum muab cov ntaub ntawv pov thawj ISO 13485.
- Muaj peev xwm ua tau: Extrusion precision, ntau-lumen ua, thiab muaj peev xwm ua tau raws li qhov siab ntev.
- Customization Support: Muaj peev xwm tsim cov ntaub ntawv nrog ID / OD, phab ntsa tuab, thiab txheej txheej.
- Kev Pov Hwm Zoo: Hauv - kev tshuaj xyuas kab, kev sim batch, thiab cov ntaub ntawv txhawb nqa rau kev ua raws cai.
- Prototyping thiab Technical Support: Kev sib koom tes thaum R&D theem kom ua kom zoo dua li cov kab hauv cov khoom txwv.
- Kev ntseeg tau thoob ntiaj teb: Kev xa khoom raws sij hawm, kev tsim khoom loj tuaj, thiab muaj peev xwm thaub qab.
Xaus:
PTFE liners yog ib qho tseem ceeb ntawm cov khoom siv kho mob, muab cov kev sib txhuam qis qis, tshuaj tiv thaiv, thiab biocompatibility. Xaiv txoj cai PTFE liner thiab tus neeg muag khoom cuam tshuam rau kev ua haujlwm ntawm cov cuab yeej, cov txiaj ntsig kev kho mob, thiab kev ua raws li kev cai. Cov neeg tsim khoom yuav tsum ua qhov tseem ceeb rau cov neeg xa khoom nrog cov ntawv pov thawj kho mob- qib kev txawj ntse, muaj peev xwm extrusion meej, thiab kev sib koom tes txhawb nqa.
