Hauv kev kho mob consumables, ekoob piduralyog hailed li "art on a needle's tip." Dab tsi zoo nkaus li yog rab koob hlau zoo tib yam tiag tiag embodies kev txiav- ntug kev ua tiav los ntawm ntau yam kev qhuab qhia, suav nrog cov ntaub ntawv tshawb fawb, precision mechanics, nto engineering, thiab kev tswj kom zoo. Niaj hnub no, cia peb nqis mus rau hauv kev cob qhia ntawm ib sab saum toj -tier chaw tsim tshuaj paus thiab tshawb nrhiav tag nrho cov txheej txheem tom qab tsim ib rab koob epidural tsim nyog.

Kauj Ruam 1: Kev Tswj Khoom Siv - "Kev Tshuaj Ntsuam Xyuas Kev Kho Mob" ntawm Kev Kho Mob- Qib Stainless Hlau

Nws tag nrho pib nrog kev xaiv cov khoom siv raw. Cov hlau tsis muaj steel siv rau cov koob epidural yuav tsum yog austenitic stainless hlau (xws li SUS304, 316L), muaj peb yam tseem ceeb:

• Biocompatibility:Dawb los ntawm impurities nrog siab nickel tso tawm, thiab dhau ISO 10993 kev ntsuam xyuas rau cytotoxicity, rhiab heev, thiab intradermal tshuaj.
• Corrosion kuj:Resistant rau lub cev, tshuaj tua kab mob, thiab tshuaj loog hauv zos, kom tsis txhob xeb thaum lub sij hawm ntev - cog rau hauv lub cev.
• Mechanical Balance:Rockwell hardness yuav tsum tau khaws cia ntawm HRC 38-42. mos heev thiab nws tsis tuaj yeem nkag ligaments; nyuaj heev thiab brittleness nce, ua rau yooj yim tawg.

Txhua batch ntawm steel yuav tsum tau soj ntsuam spectral thiab tensile xeem ua ntej muab khaws cia. Tsuas yog cov ntaub ntawv uas nws muaj tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab ua tau raws li cov qauv raug tso cai nkag mus rau cov kab ntau lawm.

Kauj Ruam 2: Tsim Theem – Tus Qauv ntawm Micro-Kev Ua Haujlwm Txias

Hloov cov pas nrig puag ncig mus rau hauv rab koob hollow nrog cov curvature meej yuav tsum muaj ntau yam kev ua haujlwm txias:

• Daim duab:Sab nraud txoj kab uas hla yog maj mam txo thiab lub puab bore tsim los ntawm ib tug series ntawm tuag, nrog rau tag nrho cov txheej txheem ua tsis muaj lubrication los tiv thaiv cov roj residue. Qhov txo qis ntawm txoj kab uas hla ntawm txhua theem kos duab yog tswj nruj me ntsis hauv 0.05 hli kom tsis txhob muaj kev ntxhov siab tawg.
• Annealing:Kev ntxhov siab- nyem annealing yog ua nyob rau hauv lub tshuab nqus tsev vacuum kom tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sij hawm txias ua hauj lwm thiab kho cov khoom ductility.
• Khoov:Lub tshuab CNC dabtsi yog khoov ua cov koob raj rau hauv lub kaum ntse ntse (feem ntau 15℃-30 degree). Qhov tseeb ntawm cov kauj ruam no ncaj qha cuam tshuam rau qhov kev coj ua ntawm cov yeeb nkab qhia. Cov koob nrog qhov sib txawv tshaj 0.5℃raug tso tseg.
• Ntsej muag:Lub taub hau yog hauv av siv pob zeb diamond sib tsoo lub log ntawm ntau lub ces kaum los ua ib qho ntse, symmetrical bevel. Kev sib tsoo tsis sib xws-xws li kev sib hloov ceev, pub tus nqi, thiab cov dej txias txaus- tau ua kom zoo dua ntau pua lub sij hawm kom ntseeg tau tias cov ntug txiav tsis muaj burrs lossis chipping.

Kauj Ruam 3: Kev Kho Hniav - Kev hloov pauv ntawm "Rough" mus rau "Daim iav tiav"

Lub smoothness ntawm koob raj lub puab phab ntsa yog ib qho ntawm cov cim tseem ceeb ntawm qhov zoo. Ib qho me me protrusion lossis kev nyuaj siab tuaj yeem ua qhov chaw nkaum rau cov kab mob los yog khawb lub catheter thaum muab tso rau.

• Electrolytic polishing:Cov koob yog immersed nyob rau hauv ib qho kev daws teeb meem electrolyte, qhov twg electrochemical cov tshuaj tiv thaiv dissolve lub microscopic peaks ntawm nws nto. Cov txheej txheem no txo ​​qhov roughness ntawm Ra 0.8 μm mus rau qis dua 0.1 μm, ua tiav daim iav tiav.
• Ultrasonic tu:Ntau lub voj voog tu yog ua nyob rau hauv ib lub da dej ultrasonic uas muaj alkaline detergent kom tshem tawm cov roj seem, khib nyiab, thiab electrolyte los ntawm cov txheej txheem machining. Tom qab ntxuav, cov koob yuav tsum tau soj ntsuam particle- tom qab yaug nrog dej ntshiab, cov kua dej yaug yog sau thiab tshuaj xyuas hauv qab lub tshuab ntsuas kom suav cov khoom loj dua lossis sib npaug li 5 μm; tsis pub ntau tshaj 100 hais ib milliliter.

Kauj Ruam 4: Kev Sib Tham thiab Kev Tshawb Fawb - Qhov Zero-Cov Qauv Tsis Zoo rau Kev Tshaj Tawm Kawg

Txhua lub hub yog molded los ntawm kev txhaj tshuaj, feem ntau yog ua los ntawm polycarbonate los yog ABS, thiab yuav tsum tau airtightly nias - haum nrog rab koob. Tom qab kev sib sau ua ke, txhua rab koob tau soj ntsuam hauv qab no:

• Leak xeem:Siv 3 qhov cua ntawm huab cua siab ntawm lub koob hub thiab tuav rau 10 vib nas this, saib rau txhua qhov npuas khiav tawm.
• Flow rate test:Siv cov kua dej nrog tus qauv viscosity los ntsuas tus nqi ntws los ntawm rab koob ib lub sijhawm, kom ntseeg tau tias nws phim tus nqi nominal.
• Kev ntsuam xyuas ntse:Ntsuas lub ncov quab yuam uas yuav tsum tau nkag mus rau cov khoom siv simulated siv lub ntsuas qhov ntsuas qhov tseeb; Kev sib txawv yuav tsum tsis pub tshaj ± 10%.
• Kev kuaj pom pom:Tshawb xyuas txhua rab koob hauv qab 40x lub tshuab tsom rau cov burrs lossis hooks ntawm lub taub, thiab rau flash lossis tawg ntawm lub hub.

Kauj Ruam 5: Sterilization thiab ntim - Qhov kawg Sterile Barrier

Tag nrho cov koob tsim nyog tau ua kom tsis muaj menyuam nrog ethylene oxide hauv chav huv huv (Class 10,000 lossis Chav Kawm 100), tom qab ntawd ntim rau hauv ob npaug - txheej ntim tsis muaj menyuam (pem hauv ntej: Tyvek breathable zaj duab xis; txheej txheej: kho mob- qib dialysis ntawv). Txhua pob bears ib cim UDI code traceable rau cov batch ntau lawm, tus neeg teb xov tooj, thiab cov khoom siv raw khoom.

Xaus:

Tus nqi ntawm ib rab koob epidural txawv los ntawm ob peb duas las mus rau ntau lub kaum os, nrog rau tus nqi sib txawv ntawm qhov tsis pom kev nqis peev hauv qhov zoo. Thaum tus kws kho mob tshuaj loog tuav tus rab koob Tuohy du, sov, thiab ruaj khov, lawv tsis yog tuav lub cuab yeej xwb - lawv tab tom tuav lub neej ua los ntawm suav tsis txheeb engineers, cov neeg soj ntsuam zoo, thiab cov kws kho mob kom tsis muaj menyuam. Qhov no yog kev tsim cov lus cog tseg tshaj plaws rau cov tshuaj.
