High-Precision Co-Extruded Tubing rau PTCA Balloon Catheters

Multi-Layer Co-Extruded Tubing: Siab-Kev Ua Haujlwm Zoo rau PTCA Balloon Catheters

Ntawm Carewe Medical, peb engineer advancedco-extruded tubingtshwj xeeb tsim los daws cov teeb meem kev taug qab thiab kev sib txuas lus tseem ceeb hauv PTCA balloon catheter shafts. Peb tus tswv co-extrusion thev naus laus zis ua rau muaj qhov tseeb qhov sib luag, tshwj xeeb tsis muaj kev sib txhuam profiles, thiab kev cia siab rau thermal bondability los txhim kho koj lub catheter crossability thiab pushability los ntawm tortuous coronary anatomies.

Pebax tubing

Vim li cas thiaj xaiv Co-Extruded Multilayer Tubing?

Standard ib leeg- txheej tubing feem ntau yuam kom muaj kev sib haum xeeb ntawm lub hauv paus lubrication thiab sab nrauv kev sib raug zoo. Peb cov co-cov qauv extruded tshem tawm qhov kev cuam tshuam tag nrho los ntawm kev sib xyaw cov khoom siv sib txawv rau hauv ib qho, seamless microscopic phab ntsa profile.

Ultra-Low Friction Inner Layer (HDPE / Custom Blend):Ua kom tsis muaj kev siv dag zog taug qab thiab kev sib pauv hloov pauv tau yooj yim, txo cov kev sib txhuam quab yuam thaum cov txheej txheem nyuaj.
Optimized Outer Bonding Layer (Pebax® / Nylon 12):Tso cai rau muaj zog, ncaj qha thermal laser vuam mus rau qhov sib thooj ntawm cov ncej thiab cov zais pa, tshem tawm qhov xav tau rau cov tshuaj lom neeg ua phem lossis cov khi hauv zos- txheej.
Zoo heev Kink Resistance & Pushability:Peb precision co-extrusion crossheads optimize molecular orientation anisotropy, muab torque kis tau zoo heev thiab siab tawg resilience nyob rau hauv siab -siab balloon deflation cycles.

PTCA Application & Optimization Case Studies

Peb cov co-extruded tubing ua haujlwm raws li cov khoom siv raw lossis parison rau coronary balloon shafts, tshwj xeeb nrawm- pauv (Rx) chaw nres nkoj, thiab tshaj -- hlau (OTW) shafts sab hauv. Los ntawm kev txav los ntawm ib qho - txheej extrusion mus rau Carewe Medical's multi- txheej co-extrusion technology, ntiaj teb no PTCA manufacturers tau tshaj tawm txog li 25% nce hauv balloon laser-welding yield tus nqi thiab kev ua tau zoo heev hauv kev hnia- balloon hom kev kawm.

Cov lus nug nquag nug (FAQ)

Q1: Puas yog koj cov co-extruded raj puas muaj cov txheej txheem delamination thaum lub zais pa folding lossis kev sim siab tawg?

A1: Tsis yog. Peb siv cov polymer tshwj xeeb khi-txheej txheej thiab cov khoom sib koom ua ke-extrusion tuag lub taub hau uas yaj- khi cov kev sib tshuam hauv qhov kub thiab txias. Cov khaubncaws sab nraud povtseg ua raws li ib qho kev sib xyaw matrix thiab yuav tsis delaminate txawm tias thaum tawg siab tshaj 30 atm.

Q2: Peb puas tuaj yeem hloov kho qhov ntev thiab cov phab ntsa profile kom nrawm - pauv (Rx) catheter tsim?

A2: Yog. Peb tuaj yeem hloov kho dual -lumen thiab coaxial co-extrusion nrog cov hom phiaj ID / OD profiles raws nraim li koj PTCA cov lus qhia xaim thiab cov lus qhia tshwj xeeb. Txheem stocking profiles kuj muaj rau kev ua qauv sai.
