Producing koob intraosseousxav tau ntau tshaj li kev txiav cov hlau tsis muaj steel rau qhov ntev ntev. Txhuaintraosseous koob loj-txawm yog 1.5 cm, 2.5 cm, los yog 4.5 cm- yuav tsum tau nruj tswj cov txheej txheem tsim khoom raws li nws lub hom phiaj kho mob daim ntawv thov. Txawm hais tias tag nrho peb feem ntau siv 15G sab nraud txoj kab uas hla, lawv cov qauv kev ua tau zoo sib txawv heev, muab qhov tshwj xeeb xav tau ntawm cov khoom siv science, machining raug, thiab kev ruaj ntseg zoo.

Lub hauv paus raw khoom pib nrogkho mob -qib stainless hlau tubing, feem ntau SUS304 lossis SUS316L, xaiv rau corrosion kuj thiab txhua yam muaj zog. Txawm li cas los xij, cov duab kos duab tsis txawv nyob ntawm qhov kawg koob ntev. Cov koob luv luv zoo li 1.5 cm menyuam yaus version yuav tsum tau txo qis qis, tab sis qhov tseem ceeb tshaj plaws ntawm cov ntsiab lus. Txhua qhov eccentricity nyob rau hauv phab ntsa thickness ua proportionally magnified ntawm txo qhov ntev, muaj peev xwm ua rau asymmetric tip geometry uas cuam tshuam qhov ntxig smoothness. Yog li ntawd, cov chaw tsim khoom siv inline laser gauging thaum lub sij hawm kos duab kom tswj concentricity nyob rau hauv ± 0.02 hli.

Koob tip fabrication sawv cev rau tej zaum qhov tseem ceeb tshaj plaws sib txawv nyob rau hauv intraosseous koob ntau thiab tsawg. Tag nrho peb qhov sib txawv tau txais txiaj ntsig los ntawm trocar- taw tes lossis pyramid- cov lus qhia tsim los txhawm rau txhawm rau cov pob txha cortical zoo. Txawm li cas los, lub1.5 cm koob​ xav tau lub ultra- lub kaum sab xis luv kom tiv thaiv lub hau los ntawm kev tawm ntawm medullary kab noj hniav ntxov. Los ntawm qhov sib txawv, lub4.5 cm ntev koobtuaj yeem ua rau ntev me ntsis taper, ua kom yooj yim dua kev nce qib los ntawm cov ntaub so ntswg tuab ua ntej koom nrog pob txha. Advanced CNC sib tsoo tshuab ua rau cov tuam txhab tsim kho kom haum cov kaum sab xis thiab tshem tawm qhov chaw ntawm nws tus kheej rau txhua qhov loj, ua kom zoo txiav kev ua haujlwm zoo thaum khaws cov lus qhia kev ncaj ncees.

Kev kho deg ntxiv hloov mus rau intraosseous koob loj. Electropolishing uniformly tshem tawm micro-burrs thoob plaws txhua qhov ntev, tab sis cov koob ntev dua yuav raug tshuaj xyuas ntxiv rau cov lumen smoothness. Txij li thaum lub 4.5 cm variant nthuav tawm qhov chaw siab dua - thaj tsam - rau - ntim piv, txawm tias qhov me me ntawm qhov tsis sib xws tuaj yeem cuam tshuam qhov siab - ntws infusions xav tau thaum lub sij hawm resuscitation. Qee lub tuam txhab siv cov txheej txheem hydrophobic lossis silicone lubrication xaiv - zam kev cuam tshuam nrog kev kuaj cov pob txha pob txha yog tias xav tau-tab sis ib txwm ua kom muaj kev sib raug zoo nrog kev soj ntsuam tom ntej.

Cov txheej txheem sib dhos kuj sib txawv me ntsis. Cov2.5 cm neeg laus intraosseous koob​ feem ntau suav nrog cov stylet ruaj khov nrog qhov tseeb - cov lus qhia hauv av sib piv cov cannula sab hauv txoj kab uas hla. Qhov no tiv thaiv pob txha spicules los ntawm obstructing lub lumen thaum lub sij hawm insertion. Rau qhov loj ntawm 4.5 cm, cov tuam txhab lag luam tuaj yeem txhawb nqa lub hub - rau - cannula hlws ris nrog crimping lossis nplaum nplaum kom tiv taus siab dua torsional rog ntsib thaum sib sib zog nqus ntxig. Meanwhile, lub diminutive 1.5 cm koob preoritizes tsawg profile hubs kom txo tau tag nrho cov cuab yeej qhov siab, kev txhim kho maneuverability nyob rau hauv me nyuam mos resuscitation scenarios.

Cov txheej txheem ntim khoom thiab ua kom tsis muaj menyuam ua tiav qhov loj - lub voj voog tsim tshwj xeeb. Txhua koob intraosseous yog ib tus zuj zus muab ntim rau hauv Tyvek® hnab luam tawm nrog cov cim ntev tsis pom tseeb-ib qho tseem ceeb tiv thaiv kev siv tsis raug. Sterilization validation, tshwj xeeb tshaj yog ethylene oxide (EO) cycles, suav rau variations ntawm huab hwm coj thiab ceev ntawm qhov ntau thiab tsawg. Load mapping ua kom cov roj nkag mus rau hauv cov pa thiab kev ua haujlwm aeration tsis hais qhov ntev ntawm rab koob. Kev ntsuam xyuas kev laus kom ceev kom paub tseeb tias txee- lub neej ruaj khov thoob plaws tag nrho tsev neeg cov khoom.

Cov chaw saib xyuas kev tswj xyuas zoo qhia txog qhov loj me no - nyob ntawm qhov sib txawv. Hauv - cov txheej txheem kev tshuaj xyuas suav nrog kev ntsuas qhov ntev ntawm lub zeem muag, kev txheeb xyuas lub kaum sab xis uas siv cov khoom siv kho qhov muag, thiab kev nkag mus rau cov pob txha hluavtaws analogues replicating me nyuam yaus piv rau cov neeg laus cortical ntom. Kev ntsuam xyuas qhov kawg tso tawm suav nrog qib kev ua kom tsis muaj menyuam (SAL) validation, kuaj pyrogen, thiab xyuas txhua yam kev ncaj ncees. Qhov tseem ceeb, cov tuam txhab lag luam yuav tsum ua kom pom kev sib txuas ntawm txhua qhov khoom tiav rov qab mus rau nws cov khoom siv tshwj xeeb, tshuab khiav, thiab cov neeg ua haujlwm batch.

Rau cov neeg yuav khoom, paub txog cov kev tsim khoom lag luam intricacies tseem ceeb vim li cas tus nqi tsev ib leeg tsis tuaj yeem txiav txim siab tus nqi. Tus neeg muag khoom muab tus nqi sib tw hauv cov koob txhaj tshuaj tab sis tsis muaj cov ntaub ntawv pov thawj ntawm qhov loj - cov txheej txheem tshwj xeeb tswj tau ua rau muaj kev pheej hmoo tsis txaus ntseeg. Hloov chaw, pawg neeg yuav khoom yuav tsum ua qhov tseem ceeb rau cov tuam txhab lag luam uas qhia txog kev sib koom ua ke ntsug- los ntawm kev kos cov raj los ntawm kev ua kom tsis muaj menyuam- thiab txaus siab muab cov ntaub ntawv qhia txog kev ua haujlwm li cas.intraosseous koob lojUa tau raws li ISO 13485 thiab cov kev cai hauv cheeb tsam. Xws li kev mob siab ua kom ntseeg tau qhov kev ua tau zoo thaum lub vib nas this suav rau hauv cov hlab ntsha tuaj yeem tshwm sim.
