Vygon Pediatric Micro-Kev tsim khoom: Tiv thaiv Venous Plexus Nrog 26G / 27G Fine-Gauged Needles

Thaum qhov kev thov ntawm covDisposable Sterile Medical Spinal Needlenqaim mus rau pediatrics, manufacturing complexity escalates exponentially. Fab Kis tus kws tshaj lij Vygon SA ua tau zoo hauv qhov no, qhov twg 26G thiab 27G koob yog tus qauv. Nyob rau hauv cov me nyuam mos, tus txha caj qaum yog minuscule, thiab venous plexus yog ntau thiab intimately adhered rau dura; ib qho yuam kev caw tuaj yeem mob ntshav siab.

Vygon qhov kev sib tw tseem ceeb yog tubing. Ib rab koob 27G (0.4mm OD) yuav tsum muaj lub lumen sab hauv kom txaus rau CSF ntws, xav tau phab ntsa thicknesses hauv qab 0.05mm. Vygon qhov chaw aerospace-qib stainless capillary raj, ua tiav ntawm ntau- dhau qhov kos duab txias. Cov kev ntxhov siab meej-relief annealing yog ib qho tseem ceeb kom tswj tau qhov nruj tsis muaj brittleness ntawm qhov ntev.

Qhov thib ob hurd yog qhov sib tsoo. Kev sib tsoo tshuab sib tsoo yog ntxhib heev rau 27G cov lus qhia. Vygon ntiav Electrical Discharge Machining (EDM) lossis femtosecond lasers los tsim cov cwj mem los yog luv luv -bevel profiles. Qhov tseem ceeb, sab -chaw nres nkoj ntug tau txais tshwj xeeb radiusing. Raws li electron microscopy, Vygon cov lus qhia nthuav tawm zoo kawg nkaus, burr-dawb orifices. Qhov no (qhov kawg) tiav yog qhov tseem ceeb; ib qho micro-burr tuaj yeem ua raws li barb, snagging fragile neonatal veins thiab ua rau "ntshav CSF" piav.

Thirdly, stylet haum yog qhov tseem ceeb. Hauv cov koob zoo, qhov clearance ntawm stylet thiab lumen yuav tsum yog micron - leej. Kev tshem tawm ntau dhau tso cai rau cov ntaub so ntswg coring lossis ntshav rov qab; kev tshem tawm tsis txaus ua rau kev sib khi, muaj kev pheej hmoo ntawm cov ncej buckling. Vygon qhov kev sib tsoo tsis sib haum ua tiav qhov kev sib npaug zoo, tiv thaiv cov stylet los ntawm kev ua lub plunger uas rub cov ntshav mus rau hauv rab koob thaum tshem tawm.

Tsis tas li ntawd, Vygon muaj cov ncej luv luv (piv txwv li, 25mm lossis 40mm). Standard 90mm koob yog unwieldy nyob rau hauv neonates, nce tip wobble thiab muaj kev pheej hmoo ntawm sib sib zog nqus insertion. Vygon cov koob luv luv muaj qhov siab - qhov sib txawv qhov tob. Txij li thaum lub tactile "pop" ntawm ligamentum flavum yog qhov hloov maj mam nrog cov ntsuas zoo, cov cim no muab cov ntsiab lus tob tob -ib qho kev pab tseem ceeb rau cov tub ntxhais kawm ("kev paub tsis txaus"). Vygon qhia tau hais tias hauv kev tsim cov koob txhaj tshuaj, "me" tsis txhais tau yooj yim; es, kev txawj ntse ntawm micro- nplai sawv cev qhov tseeb zenith ntawm kev ua tau zoo.
