Raws li intraosseous nkag mus hloov los ntawm cov txheej txheem niche mus rau tus qauv- ntawm- kev saib xyuas, kev tshuaj xyuas kev tswj xyuas hnyav dua - tshwj xeeb yog hais txog koob intraosseousqhov lojntau haiv neeg. Cov cuab yeej siv txij li 1.5 cm menyuam yaus mus rau 4.5 cm ntev bariatric poob rau hauv cov ntawv tshaj tawm ua haujlwm- kev soj ntsuam kev lag luam thoob ntiaj teb. Cov neeg tsim khoom muab kev lag luam thoob ntiaj teb yuav tsum taug qab cov txheej txheem nyuaj suav nrog US FDA 21 CFR Part 880, European Union Medical Device Regulation (MDR) 2017/745, thiab Tuam Tshoj txoj kev saib xyuas NMPA. Tseem ceeb heev, kev ua raws cai feem ntau txawv raws li cov lus qhia tau hais ncaj qha rau qhov ntev ntawm rab koob.

Nyob rau hauv FDA txoj cai, cov koob txhaj tshuaj intraosseous feem ntau yog cais raws li Class II cov cuab yeej kho mob, xav tau 510 (k) tshem tawm. Kev xa ntawv ua tiav yuav tsum tsim kom muaj qhov sib npaug ntawm cov khoom lag luam raug cai, nrog rau kev saib xyuas tshwj xeeb rauxav siv cov lus haisQhia txog tus neeg mob qhov hnyav ntau raws li qhov ntev ntawm rab koob. Piv txwv li, ib qho 510 (k) npog ib lub 1.5 cm ntaus ntawv yuav hais qhia rau cov neeg mob (<40 kg), whereas a 4.5 cm version targets obese adults. Manufacturers must submit performance data-including insertion force testing across simulated tissues of varying thicknesses-demonstrating safe and effective use within those defined populations. Importantly, combining multiple sizes under one 510(k) is permissible only if each size shares identical technological characteristics and clinical validation supports expanded labeling.

EU MDR nce kev cia siab ntxiv. Annex I's General Safety and Performance Requirements qhia meej meej txog kev tsim cov cuab yeej vis-à-vis tus neeg mob lub cev. Rau cov koob intraosseous, qhov no txhais ua nrujCov ntaub ntawv soj ntsuam kuaj mob (CERs)substantiating kev ruaj ntseg thov rau txhua qhov loj variant. Cov neeg tsim khoom yuav tsum sau cov ntaub ntawv tshuaj xyuas thiab, qhov twg muaj qhov sib txawv, tsim cov ntaub ntawv kho mob tshiab kom paub meej tias qhov kev nkag mus rau qhov tob uas tsis muaj ntau dhau ntawm lub cortex perforation. Cov ntaub ntawv tswj kev pheej hmoo raws li ISO 14971 yuav tsum cais hom Kev Tsis Ua Haujlwm thiab Kev Ntsuam Xyuas Cov Teebmeem (FMEA) rau luv luv, nruab nrab, thiab ntev koob, lees paub qhov sib txawv ntawm cov phom sij txaus ntshai - piv txwv li, kev loj hlob phaj raug mob nrog 1.5 cm koob tiv thaiv cov paj hlwb muaj peev xwm nrog 4.5 cm li. Tshaj tawm -kev ua lag luam soj ntsuam ua raws- nce (PMCF) cov phiaj xwm yuav tsum zoo ib yam li cov ntaub ntawv sau los ntawm rab koob loj txhawm rau txheeb xyuas cov teeb liab kev nyab xeeb.

Tuam Tshoj tus NMPA tswj hwm kev qhuab qhia zoo sib xws los ntawm nws Txoj Cai Kev Xeem. Intraosseous koob tau txais kev ntsuam xyuas lub cev, tshuaj lom neeg, thiab tshuaj lom neeg ntawm cov chaw kuaj pom. Cov qauv xeem yuav tsum sawv cev rau qhov phem tshaj plaws - rooj plaub- txhais tau tias qhov ntev tshaj plaws (4.5 cm) thiab luv tshaj (1.5 cm) koob feem ntau ntsib lub roj teeb dav tshaj plaws ntawm kev ntsuas. YY / T cov qauv tswj cov koob sharpness, kev sib txuas lub zog, thiab corrosion kuj. Qhov tseem ceeb, NMPA yuav tsum tau sau meej meej ntawm koob ntev hauv millimeters nrog rau qhov ntsuas qhov loj ntawm ob qho tib si thawj ntim thiab cov ntawv qhia ntawv. Cov neeg tsim khoom xa tawm mus rau Tuam Tshoj yuav tsum xyuas kom meej tias lawv cov qauv kos duab ua raws li qhov yuav tsum tau nthuav tawm yam tsis muaj qhov tsis meej.

Tshaj li qhov kev tso cai ua lag luam thawj zaug, kev ua raws cai txuas ntxiv mus txuas ntxiv ntawm kev tshaj tawm ruaj khov- kev soj ntsuam kev lag luam (PMS). Cov kev ceeb toom tsis zoo tshwm sim-xws li FDA's MAUDE database, EUDAMED nyob rau hauv MDR, thiab Tuam Tshoj's Adverse Event Monitoring System- ntes cov xwm txheej uas muaj feem cuam tshuam rau kev xaiv qhov loj me lossis kev ua haujlwm tsis zoo. Manufacturers dais lub luag hauj lwm rau trending xws cov ntaub ntawv los ntawmintraosseous koob loj, tshawb xyuas cov hauv paus hauv paus, thiab siv cov kev kho kom raug. Piv txwv li, ib pawg ntawm qhov tsis ua tiav nrog 2.5 cm koob nyob rau hauv cov neeg mob rog rog tuaj yeem ua rau cov ntawv kho dua tshiab uas hais txog qhov tseem ceeb ntawm cov cim palpable lossis nce qib ntawm 4.5 cm.

Ntim thiab daim ntawv lo yog lwm qhov kev sib ntaus sib tua. Txhua koob intraosseous loj yuav tsum tso tawm unambiguous ntev tshaj tawm nyob rau hauv metric units. Cov cim ua raws li ISO 15223-1 (piv txwv li, "Tsis txhob rov siv dua," "Ib zaug- siv nkaus xwb") yog qhov yuav tsum tau ua. Cov lus qhia rau kev siv (IFU) yuav tsum muaj qhov qhia meej qhov loj me algorithms coj cov kws kho mob mus rau kev xaiv kom tsim nyog raws li tus neeg mob qhov hnyav, BMI, lossis anatomical palpability. Qee cov tuam txhab xav txog yav tom ntej nthuav tawm daim ntawv IFUs nrog QR cov lej txuas mus rau cov kev qhia hauv online uas qhia txog cov txheej txheem ntsuas kom zoo rau txhua qhov loj.

Thaum kawg, kev tswj hwm zoo nyob ib puag ncig cov koob txhaj tshuaj intraosseous qhia txog kev cog lus rau cov neeg mob kev nyab xeeb thiab kev nkag mus rau thoob ntiaj teb kev lag luam. Cov kws tshaj lij yuav tsum thov cov ntawv theej ntawm daim ntawv pov thawj tam sim no-FDA 510(k) cov ntawv tshem tawm, EU MDR Daim Ntawv Pov Thawj Ua Raws Cai, NMPA daim ntawv pov thawj daim ntawv teev npe-thiab xyuas kom meej tias cov qauv sau ua raws li qhov 1.5 cm, 2.5 cm, thiab 4.5 cm variants muaj. Qhov tseem ceeb sib npaug yog kev soj ntsuam seb tus neeg muag khoom puas tswj hwm Pharmacovigilance System Master File sau cov haujlwm PMS. Tsuas yog cov tuam txhab lag luam uas lees paub qhov kev ua raws li kev coj ua raws li qhov tsim nyog tau txais kev txiav txim siab ua cov koom tes zoo hauv kev muab lub neej- txhawb nqa cov khoom siv nkag mus rau hauv lub cev.
