15 gauge, 2.5 cm neeg lauskoob intraosseousyog lub ntsiab lus tseem ceeb tshaj plaws hauv kev lag luam intraosseous koob, nrog rau kev pab cuam dav dav ntawm cov neeg coob coob thiab cov xwm txheej kho mob. Nws tau raug lees paub rau cov tub ntxhais hluas tshaj 40 kg thiab tsis yog - cov neeg laus rog, thiab tseem tuaj yeem siv nyab xeeb rau tibial intraosseous puncture nyob rau hauv cov neeg laus rog rog nyob rau hauv qhov chaw ntawm palpable tibial tuberosity, npog ntau tshaj 90% ntawm cov neeg laus cov neeg laus intraosseous puncture cov txheej txheem kev kho mob tseem ceeb hauv ntiaj teb no.

Qhov ntev ntawm 2.5 cm yog qhov zoo tshaj plaws tsim los ntawm kev sau cov ntaub ntawv loj ntawm cov neeg laus cov ntaub ntawv kho mob anatomical. Cov neeg laus dua 40 kg tau tsim cov pob txha pob txha, cov pob txha tibial cortical thickened thiab tob medullary kab noj hniav. Lub 1.5 cm me me koob yog luv dhau los nkag mus rau hauv cov pob txha cortical zoo, uas ua rau kev sib tsoo tsis ua haujlwm thiab tsis siv cov qauv. Qhov ntev ntawm 2.5 cm tuaj yeem hloov kho kom haum rau cov pob txha ntawm cov neeg laus thiab cov tub ntxhais hluas, ruaj khov nkag mus rau hauv cov pob txha cortical kom ncav cuag medullary kab noj hniav, kom ntseeg tau tias ua tiav cov kua dej ua tiav, kev xa tshuaj thiab kev ua haujlwm ntawm cov pob txha pob txha. Kev sib koom ua ke 15G rab koob txoj kab uas hla tau raug txheeb xyuas los ntawm kev sim tshuaj thoob ntiaj teb, uas tsis tsuas yog ua kom muaj cov kua dej txaus txaus thiab cov qauv coj mus kuaj, tab sis kuj zam qhov mob ntau dhau ntawm qhov txhab thiab mob hnyav tom qab phais mob tshwm sim los ntawm cov koob loj loj.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm tus qauv tus neeg laus intraosseous koob yog hloov tau yooj yim rau cov neeg mob rog. Hauv kev xyaum kho mob, ntau tus neeg laus rog rog tsis xav tau ultra- rab koob ntev ntev. Tsuav tus neeg teb xov tooj tuaj yeem kov tus neeg mob lub tibial tuberosity positioning point, 2.5cm tus qauv koob tuaj yeem ua tiav qhov sib thooj tibial intraosseous puncture. Qhov no zoo heev txhim kho qhov yooj yim ntawm kev siv cov cuab yeej siv kho mob, zam kev pov tseg ntawm cov khoom siv kho mob uas tshwm sim los ntawm kev hloov ntau zaus ntawm kev sib txawv ntawm cov koob, thiab txhim kho kev ua haujlwm ntawm kev kuaj mob xwm txheej ceev thiab kev kho mob.

Hais txog kev ua tau zoo ntawm cov khoom lag luam, tus qauv tus neeg laus intraosseous koob txais siab - lub zog stainless hlau cov khoom, uas yog hnav- tiv taus, siab- tiv taus thiab tsis yooj yim rau deform, hloov mus rau qhov siab - ntom thiab siab - hardness yam ntxwv ntawm cov neeg laus cov pob txha. Qhov zoo polished rab koob tuav tuav ntev - ntev sharpness, txo kev ua hauj lwm tsis kam thiab txhim kho puncture kev nplij siab. Cov khoom no txais cov qauv kev ntim khoom tsis muaj menyuam, uas yooj yim rau kev kho mob xwm txheej ceev thiab siv txhua hnub. Kev cia siab rau nws qhov kev ua tau zoo, kev hloov pauv dav dav thiab kev ua haujlwm siab, 15G 2.5cm tus neeg laus intraosseous koob tau dhau los ua qhov zoo tshaj plaws - muag cov khoom lag luam tseem ceeb hauv kev lag luam, thiab tseem yog cov khoom tseem ceeb rau cov cuab yeej siv kho mob kom xa cov khoom siv koob tshuaj intraosseous.
