3. Vacutainer koob: Muaj kev nyab xeeb thiab ntau yam qauv npaj
Needle Gauge Range:20G-22G (feem ntau 21G)
Covkoob vacutaineryog ib rab koob thib ob uas haum rau hauv lub hnab yas, tso cai rau ntau cov hlab ntshav kom tau ntim rau hauv ib lub venipuncture. Qhov noCov cuab yeej sau ntshavyog ib feem tseem ceeb ntawm cov txheej txheem kuaj niaj hnub no.
- Enables ceev, ntau tus qauv sau
- Minimizes kev pheej hmoo ntawm kev kis kab mob
- Standardized ntim rau kuaj qhov tseeb
Siv dav hauv cov chaw kuaj mob thiab chaw kho mob qhov chaw ua haujlwm thiab kev nyiam huv yog qhov tseem ceeb. Lub tshuab nqus tsev vacutainer yog ib qho tseem ceeb hauv kev tshaj lijkev kho mobchains rau kev kuaj ntshav siab.
4. Lancet Needle: Rau Capillary Blood Sampling
Needle Gauge Range:26g-30g
Lancet koob yog me me, caij nplooj ntoos hlav-loadedkhoom siv kho mobtsim los rau pricking daim tawv nqaij kom sau cov ntshav capillary. Lawv feem ntau yog siv ib zaug thiab pov tseg.
- Qhov mob me me thiab kho tau sai
- Qhov zoo tshaj plaws rau kev kuaj ntshav qabzib thiab cov ntim qis
- Yooj yim siv hauv tsev lossis hauv chaw kho mob
Lancets feem ntau yog siv rau hauv kev tswj ntshav qab zib, kev saib xyuas menyuam mos, thiab ntsuas ntiv tes. Raws li ib tug compact thiab huv sikev kho mob, lawv yog ib qho tseem ceeb hauv kev kuaj mob thiab cov khoom siv kho mob ntawm tus kheej.
