Yuav Ua Li Cas Sterilize Medical 3D Printed Parts?

Cov ceg txheem ntseeg siab ntawm "Tau Txais Nws Huv" hauv Kev Kho Mob Ntiaj Teb

Kev kho mob-Cov Kab Mob Sib Kis (HAIs) tseem yog ib qho teeb meem loj heev. Lawv cuam tshuam ntau lab tus neeg mob txhua xyoo thiab raug nqi kho mob ntau lab lab. Ib qho kev cog qoob loo uas tsis muaj kab mob los yog rov siv tau dua tuaj yeem ua rau kev phais kho dua tshiab, mus pw hauv tsev kho mob ntev, sepsis, lossis phem dua.

Kev tsim khoom ib txwm ua tau yooj yim geometries nrog rau qhov chaw siv tau. SLM 3D Printing thiabHP 3D luam ntawv(Metal Jet) ua kom muaj cov lattices monolithic, sab hauv, thiab tus neeg mob -cov qauv tshwj xeeb uas txhim kho cov txiaj ntsig tau zoo - tab sis lawv kuj tsim qhov chaw zais uas cov kab mob thiab cov khoom seem tuaj yeem muaj sia nyob.

Qhov no yog vim li cas sterilization tsis tuaj yeem yog qhov kev xav tom qab. Nws yuav tsum tau engineered rau hauv ib feem ntawm lub tswvyim theem.

Yog vim li cas Sterilizing Additive Parts yog ib tug txawv Beast tag nrho

Powder txaj fusion qhov chaw (SLM) pib nrog qhov chaw ntxhib (Ra 8-25 μm), qee qhov melted hais, thiab muaj peev xwm micro-porosity. HP Hlau Jet qhov chaw muaj kev sib tw sib txawv - ntsuab siab dua-ib feem porosity ua ntej sintering, uas cuam tshuam rau kev ntxuav thiab tawm.

Cov cuab yeej cuab tam bio- hnyav thiab thaiv kev nkag mus rau cov tshuaj tua kab mob. Ua kom tiav Sterility Assurance Level (SAL) ntawm 10⁻⁶ yuav tsum tau txiav txim siab tsim, ua kom huv huv, thiab ua kom tsis muaj menyuam. Qhov no yog qhov khoom siv kho mob muaj peev xwm 3D luam ntawv chaw tsim khoom ua qhov tseem ceeb.

Nkag siab txog thev naus laus zis: Yuav ua li cas Txoj Kev Luam Ntawv cuam tshuam rau kev ua kom tsis muaj menyuam

Selective Laser Melting (SLM) ua rau siab - qhov chaw ntom ntom nrog cov khoom zoo heev. Nws yog qhov kev xaiv zoo tshaj plaws rau kev thauj khoom -cov kabmob cog. Nws cov qauv ntom pab nrog kev ua kom tsis muaj menyuam thaum cov hmoov av tshem tawm, tab sis cov lattices nyuaj tseem yuav tsum tau ua tib zoo tsim cov txheej txheem.

HP Hlau Dav Hlau (Binder Jetting) muab cov nqi tsim sai dua rau cov khoom loj dua. Txawm li cas los xij, cov khoom yuav tsum tau sintering thiab infiltration, uas cuam tshuam qhov porosity thiab outgassing lub sij hawm thaum EtO sterilization.

Qhov zoo tshaj plaws kev cai hlau 3D luam ntawv Hoobkas xaiv cov cuab yeej raws li txoj kev ua kom tsis muaj menyuam zaum kawg, cov khoom siv kho tshuab, thiab ntim ntau lawm.

Ethylene Oxide (EtO) Sterilization: Qhov Kev Xaiv Zoo Tshaj Plaws rau Cov Geometries Complex

EtO roj feem ntau yog qhov kev xaiv zoo tshaj plaws rau kev sib txuam 3D luam ntawv hlau qhov chaw vim tias nws nkag mus tob rau hauv cov lattices thiab cov channel sab hauv uas chav tsis tuaj yeem ncav cuag tau zoo.

EtO ua haujlwm li cas:

Cov ntsiab lus: 450-1200 mg / L

Kub: 30-60 degree

Cov av noo: 40-80%

Lub voj voog: 12-48 teev (nrog rau aeration)

Qhov zoo:

Zoo heev nkag mus rau hauv complex geometry.

Tsawg kub (muaj kev nyab xeeb rau cov qauv tsim rhiab).

Zoo tiv thaiv ib tug dav spectrum ntawm microorganisms.

Kev sib tw:

Ntev mus ntev.

Xav tau kom huv si aeration kom tshem tawm cov residuals.

Txoj cai tswj xyuas vim muaj toxicity.

Cov cuab yeej kho mob tshaj lij 3D luam ntawv chaw tsim khoom yuav muaj kev lees paub EtO cov txheej txheem thiab muab cov ntaub ntawv soj ntsuam seem.

Muab piv rau "Peb Loj" Txoj Kev Sterilization rau Hlau Additive Manufacturing 3D Printing

Steam Autoclaving Fast, zoo, thiab tsev kho mob - phooj ywg. Qhov zoo tshaj plaws rau khoom lossis yooj yim -lattice titanium thiab 316L qhov chaw. Kev kub siab yuav tsum tau ua tib zoo tsim kom tsis txhob muaj kev cuam tshuam.

Gamma Radiation Kev nkag mus tob, tsis muaj cua sov, zoo tagnrho rau cov khoom ntim khoom. Zoo heev rau bulk sterilization ntawm cov lag luam wholesale 3D luam ntawv phais instruments.

Vaporized Hydrogen Peroxide (VHP) Cov voj voog nrawm, qhov kub thiab txias. Zoo rau cov cua sov- cov rooj sib txoos rhiab tab sis muaj kev nkag mus rau hauv cov lattices tuab.

Technical Sib piv Table

Yuav ua li cas koj xaiv ntawm hlau tuav lub tshav kub

Titanium (Ti6Al4V): Tsis tshua muaj kev sib tw nrog autoclaving. Nws cov txheej txheem oxide ruaj khov muab kev ua haujlwm ntev ntev -.

Stainless hlau (316L): Lub workhorse rau reusable cov cuab yeej. Electropolishing ho txhim kho kev ua tau zoo tom qab rov ua dua.

Cobalt-Chrome: Muaj zog thiab hnav- tiv taus, tab sis yuav tsum muaj kev tswj xyuas lub voj voog kom txo qis oxidation.

Ib tug txhim khu kev qha 3D luam titanium cov khoom siv kho mob yuav muab cov ntaub ntawv pov thawj kom tsis muaj menyuam rau txhua qhov hlau thiab geometry.

Kev tshem tawm hmoov thiab Bio- hnyav

Trapped hmoov yog tus uas ntsiag to killer. Txawm tias microscopic npaum li cas tuaj yeem tiv thaiv kab mob. Kev tu kom huv si (ultrasonic, siab - lub zog nqus dej) yuav tsum ua ntej kom tsis muaj menyuam. Kev lees paub ntawm kev huv huv yog qhov yuav tsum tau ua.

Regulatory toj roob hauv pes

Sterilization yog txheej txheem tshwj xeeb. Koj xav tau cov ntaub ntawv pov thawj (IQ/OQ/PQ), cov cim qhia txog roj ntsha, thiab cov kev ntsuas seem. FDA thiab ISO 13485 auditors cia siab tias muaj pov thawj tseeb ntawm SAL 10⁻⁶.

Xaiv cov cuab yeej kho mob 3D luam ntawv chaw tsim khoom nrog kev paub dhau los hauv kev tswj kom tsis muaj menyuam validation.

Tiag -Lub Ntiaj Teb Scenario

Ib tug neeg tau tsim ib lub titanium txha nraub qaum tawb nrog tuab lattice. Standard autoclaving ua tsis tau tejyam nyob rau hauv qhov chaw. Peb rov tsim cov channel kom zoo dua cov roj ntws, ua kom zoo dua qhov chaw tiav, thiab siv tau EtO raws tu qauv. Cov cuab yeej dhau tag nrho cov kev ntsuam xyuas thiab mus txog kev siv tshuaj zoo.

Scaling los ntawm ib feem mus rau kev lag luam wholesale ntau lawm

EtO muaj ntau dua rau ib tus nqi - voj voog tab sis ntsuas tau zoo. Autoclaving yog pheej yig tshaj rau cov khoom sib xws. Kev lees paub yog kev nqis peev uas tiv thaiv kev rov qab los thiab qeeb. Tus khub muaj zog optimizes tag nrho cov haujlwm.
