Pain Point

Deg tsis xws luag ntawm koob tshuaj hypodermic tubing yog ib qho ntawm cov khoom siv kho mob tsis ua haujlwm. Cov khawb me me, qhov seem ntawm lub laser slag thiab cov kab mob ntawm qhov chaw ua rau mob, hemolysis thiab thrombus tsim hauv cov ntshav -hu rau daim ntawv thov. Cov txheej txheem Passivation ua tsis raug tawm ntawm chromium- thaj chaw depleted thiab ua rau muaj kev pheej hmoo corrosion. Tom qab laser txiav hypodermic koob tubing, qhov npoo khaws cov txheej txheem rov qab uas tsis tuaj yeem raug tshem tawm los ntawm kev tu yooj yim. Variation nyob rau hauv nto roughness ntawm ntau lawm batch tsim inconsistent biological teb. Ntau qhov kev kho qhov chaw ua haujlwm tsis raug lees paub, yog li cov neeg soj ntsuam xyuas yuav tsis lees paub cov ntaub ntawv biocompatibility. Nitinol hypodermic koob tubing nthuav tawm cov kev cov nyom ntxiv: kev ua tsis zoo ntawm qhov chaw tuaj yeem degrade superelastic zog thiab qhia txog nickel leaching txaus ntshai. Cov pab pawg tsim qauv feem ntau saib xyuas qhov kev siv tau zoo ntawm qhov chaw thiab tsuas yog tsom mus rau qhov ntev ntev.

Txoj Cai Taw Qhia

Kev kho deg hloov kho qhov chaw sab nrauv thiab sab hauv ntawm koob txhaj tshuaj hypodermic los txhim kho biocompatibility, txo kev sib txhuam thiab txhim kho corrosion. Lub hauv paus tubing ranges Ø0.20mm txog 20mm, nrog laser txiav mus rau 0.012mm kerf dav. Tom qab kev kos duab txias thiab laser txiav, cov tubing nto yog qhov seem ntawm kev ntxhov siab, micro-burrs thiab laser recast khoom. Passivation tsim cov txheej txheem tiv thaiv chromium oxide ntawm stainless hlau los tiv thaiv corrosion. Electropolishing tshem tawm cov ncov thiab hav kom qis qhov roughness. Ultrasonic thiab hnyav tu tshem tawm cov paug paug. Rau Nitinol hypodermic koob tubing, tswj qhov chaw oxide txheej txwv nickel ion tso tawm. Kev kho deg tsis hloov cov khoom siv kho qhov muag ntawm lub raj tab sis ncaj qha tswj cov ntaub so ntswg thiab cov ntshav sib cuam tshuam. Cov npoo du txo qhov kev sib txhuam thaum lub sij hawm ntxig thiab txo cov thrombogenicity rau vascular interventional li.

Kev faib cov txheej txheem kho deg

Passivation yog tus qauv tiv thaiv- kev kho corrosion rau stainless hlau hypodermic koob tubing. Electropolishing ua tiav ultra- qhov chaw du thiab tshem tawm cov txheej txheem laser recast thiab micro-burrs. Ultrasonic tu thiab alkaline tu tshem tawm cov khoom seem thiab machining residues. Electrochemical deburring lub hom phiaj qhov npoo tom qab laser txiav rau kauv, radial thiab kev cai txiav cov qauv. Nitinol hypodermic koob raj siv thermal oxidation los tsim cov txheej txheem titanium oxide ruaj khov. Tom qab-txoj kev tshuaj xyuas kev kho mob suav nrog profileometry rau roughness, optical microscopy thiab corrosion soaking xeem. Cov txheej txheem no siv rau 304,316L, 17-7PH stainless hlau, Nitinol thiab L605 cobalt alloy tubing rau cov hlab plawv, tso zis thiab endoscopic.

Phau Ntawv Qhia Txog Kev Ua Haujlwm

Txhais cov hom phiaj ntawm qhov roughness thiab biocompatibility yuav tsum tau thaum pib ntawm hypodermic koob tubing tsim. Xaiv cov kev kho mob sib piv cov ntaub ntawv qib: passivation thiab electropolishing rau stainless hlau; Thermal oxidation rau Nitinol. Teem sijhawm kho qhov chaw tom qab laser txiav, yog li deburring thiab polishing tuaj yeem hais txog qhov tsis xws luag. Txheeb xyuas cov txheej txheem ntxuav kom ua pov thawj tshem tawm cov khoom seem thiab tshuaj lom neeg. Kuaj cov qauv kho rau corrosion kuj, nto roughness thiab hlau ion leaching. Ua kev sim biocompatibility nrog rau cytotoxicity thiab hemolysis rau ntshav -hu rau daim ntawv thov. Tswj cov txheej txheem tsis thiab cov ntaub ntawv batch kom ua tau raws li ISO13485 cov cai. Tsis txhob dhau-electropolishing uas txo cov phab ntsa tuab thiab ua rau cov tubing tsis muaj zog txhua yam.

Tswv yim Industrial Experience

Kev tsim khoom qhia tau hais tias laser recast txheej tsis tuaj yeem raug tshem tawm tsuas yog los ntawm kev ntxuav; electropolishing yuav tsum tau. Ntau tus neeg tsim khoom hla dhau kev ua haujlwm tom qab electropolishing, ua rau corrosion tsis ua haujlwm nyob rau hauv ntev - cov kua dej raug. Nitinol hypodermic koob tubing yuav tsum tsis txhob overheating thaum lub sij hawm oxidation, uas hloov pauv kub thiab ruins superelasticity. Nto roughness saum toj no cov kev txwv zoo heev ua rau muaj kev pheej hmoo thrombus hauv cov khoom siv vascular. Cov kws kho tsheb yuav tsum cais cov kev kho saum npoo av los ntawm kev tshuaj xyuas qhov ntev. Khaws cov ntawv pov thawj kho mob rau biocompatibility thiab corrosion siv rau kev soj ntsuam xyuas.

Cov ntsiab lus

Kev kho deg yog qhov tseem ceeb rau hypodermic koob tubing biocompatibility. Passivation, electropolishing thiab tu tshem tawm machining defects thiab tsim kev tiv thaiv nto txheej. Kev kho tsis haum yuav tsum tau ua kom haum rau cov hlau tsis muaj hlau piv rau Nitinol. Tshaj -kev ua cov kev pheej hmoo txo ​​cov phab ntsa. Surface validation thiab biocompatibility xeem yog yuav tsum tau ua ntej ntaus ntawv integration.

Kev Pom Zoo thiab Kev Pom Zoo

Yav tom ntej nto engineering rau hypodermic koob tubing yuav siv los tiv thaiv -thrombotic hydrophilic txheej. Cov pab pawg ntaus ntawv yuav tsum suav nrog qhov tshwj xeeb saum npoo hauv cov ntaub ntawv tswj kev tsim. Cov neeg muag khoom yuav tsum tau lees paub cov txheej txheem tu thiab kev ua haujlwm. R&D yuav tsum ntsuas qis- kev sib txhuam txheej sib xyaw ntawm laser- txiav cov koob txhaj tshuaj rau cov catheters tsawg heev.
