Lub Tshuab Dej Dej Ntawm IO Koob Manufacturers

Qhov kev sib tw rau cov koob tshuaj hypodermic zoo tib yam yog "txiav ntawm daim tawv nqaij yam tsis muaj mob"; qhov kev sib tw for IO koobs yog "xws li 2-4 hli ntawm cov pob txha cortical ntom yam tsis muaj pob txha pob txha los yog jamming"-cov no yog cov kev txiav txim siab sib txawv ntawm qhov loj. Yog li ntawd, IO koob manufacturers nqis peev lawv cov peev nyiaj R & D feem ntau nyob rau hauv "tsav kawg" es tsis yog "koob raj kawg."

Mechanical Differences Hla Peb Tsav Txoj Haujlwm

Muaj peb pawg tseem ceeb ntawm IO cov cuab yeej ntawm kev ua lag luam, nrog cov chaw tsim khoom lag luam meej meej:

• Roj teeb -Powered Drill Type (Teleflex EZ-IO, BD IO System):DC lub cev muaj zog + txo qis gearbox hloov kev kub ceev / qis torque rau qis ceev / siab torque. Thaum nkag mus rau cov pob txha cortical thiab nkag mus rau hauv medullary kab noj hniav, nws cia li "tso tawm dag zog." Qhov zoo: ceev (2-5 vib nas this), kev ua tiav siab. Qhov tsis zoo: lub cev muaj zog / roj teeb yuav tsum tau saib xyuas; tej zaum yuav tsis muaj zog hauv kev sib ntaus sib tua/kev puas tsuaj.
• Mechanical Constant-Torque Spring Type (patent route by Bard Access Systems nyob rau hauv xyoo tas los):​ Ib txheej ntawm qhov tsis tu ncua -torque springs yog nyob rau hauv lub casing. Thaum lub koob tip presses tiv thaiv cov pob txha siv axial quab yuam, lub caij nplooj ntoos hlav hloov los ntawm cov zis log mus rau lub zog cia log, tsav lub koob raj mus tig thiab laum nyob rau hauv. Thaum nkag mus rau hauv lub medullary kab noj hniav uas tsis kam poob, lub axial quab yuam raug tshem tawm, iav kev koom tes rov pib dua, thiab kev sib hloov nres. Qhov ci ntsa iab ntawm txoj hauv kev no yog tias nws yuav tsum tsis muaj roj teeb - winding lub caij nplooj ntoos hlav ib zaug tuaj yeem tsav ntau qhov ntxig, zoo tagnrho rau cov peev txheej - cov xwm txheej txwv. Tsis tas li ntawd, qhov nkhaus torque yog "tsis tu ncua," tsis zoo li cov motors uas nws pib lub zog hloov pauv tuaj yeem yooj yim tawg pob txha menyuam.
• Phau ntawv ntsia hlau-in/Ejector Type (Jamshidi-style manual, BIG ejector gun, SAM IO trigger type):Relies ntawm tib neeg lub zog los yog lub caij nplooj ntoos hlav muaj peev xwm zog. Tus nqi qis, feem ntau khaws cia hauv EMS lub hnab ev ntawv, tab sis cov kws kho mob lub log thaum drilling los ntawm cov neeg laus tibial cortex tuab, thiab ua ntej - sim ua tiav cov nqi qis dua li kev xyaum.

Engineering Points ntawm koob Tube nws tus kheej

• Pob Zeb Diamond Needle Tip (patented los ntawm Teleflex EZ-IO):Cortical pob txha yog tuab cov ntaub so ntswg; zoo tib yam bevel txiav zoo li "skid thiab deflect." Pob zeb diamond facets + kauv nti flutes tso cai rau lub ntsis mus tom rau hauv cov pob txha nto.
• Nyias phab ntsa, Loj Inner Diameter:IO infusion flow rates ncav cuag 5 L / h (proximal humerus). Txhua txhua 0.05 hli nce hauv txoj kab uas hla boosts txaus tus nqi. Yog li ntawd, ntawm 15G sab nraud txoj kab uas hla, ultra- cov phab ntsa nyias yuav tsum tau- qhov no qhia tib lub hauv paus ntsiab lus raws li "thin-phab ntsa technology" tau tham nyob rau hauv tsab xov xwm hypodermic yav dhau los, tab sis IO koob phab ntsa yuav tsum tiv taus torsion.
• Depth Marker Kab:​ Lub nplhaib dub yuav tsum nyob saum daim tawv nqaij kom paub meej tias rab koob ntev txaus -qhov no yog tus qauv EZ-IO SOP, hauv paus hauv kev tswj cov teeb meem ntawm "koob luv dhau los nkag mus rau cortex + extravasation."
• MR-Conditional:​ Teleflex tau txais kev pom zoo los ntawm FDA xyoo 2023 rau EZ- IO koob siv rau hauv MRI ib puag ncig- thawj thiab nkaus xwb IO koob nrog rau qhov kev xaiv no- ntxiv rau neuro ICU thiab hybrid OR procurement.

Manufacturers 'Patent Moats

The IO needle category has extremely high patent density, concentrated in three areas: drive mechanisms (drills/constant torque/ejectors), needle tip geometry (diamond cut, spiral blades), and safety locks (passive needle tip protection, needlestick prevention). BD tus tshiab - tiam IO "txuas tubing ua ntej kev ntxig + passive koob tip kev nyab xeeb" yog tsim los mus ncig ntawm Teleflex cov phab ntsa patent. Cov tuam txhab tsim khoom hauv tsev uas xav nkag mus rau qhov chaw no yuav tsum yog daim ntawv tso cai dhau mus txawv teb chaws patents lossis nrhiav qhov khoob hauv "qhov tsis tu ncua-torque mechanical" txoj kev uas Teleflex tsis tau them tag nrho- cov phab ntsa patent nyob ib ncig ntawm qhov kev xyaum ua tiav los ntawm Teleflex / BD yog qhov tsis txaus ntseeg.

Nug ib lo lus nug thaum lub Hoobkas tshawb xyuas:​ "Koj puas tau tsim koj lub tsav kawg ntawm koj tus kheej lossis hloov kho raws li EZ-IO?" Cov neeg uas tuaj yeem piav qhia meej txog qhov txo qis, lub zog torque, thiab kev tiv thaiv ntau dhau tom qab nkag mus rau hauv medullary kab noj hniav yog ua R & D tiag tiag; cov uas tsis tuaj yeem yog qhov zoo li thim rov qab- engineering.
