Magazi a pulasitiki apulasitiki

Zinthu zopanda magazi zosemphana ndi machubu: masiku ano, kutolera machubu chifukwa cha magazi kumapangidwa kwambiri ndi magalasi. PH of Galasi wamba ndi yosiyana kwambiri, ndipo kuthekera kwa hemolysis imakula kwambiri. Komabe, machubu oyeserera agalasi opangidwa ndi kayendedwe ka chubu amagawidwa modziwirika ndi mzere wozungulira, ndipo kuya ndi makulidwe ndi makulidwe osiyanasiyana ndizosiyana, zomwe zimatsogolera kundende. Poyerekeza ndi galasi la ndale (magalasi a mankhwala), maubwino ali odziwikiratu. Galasi landale lili ndi maubwino okakamizidwa, osasungunuka mosasungunuka, komanso ma polengo ocheperako panthawi yopanda vuto la PB2, zn + ndi fe2. Izi zitha kusintha zoyambirira za magazi, kotero machubu oyeserera agalasi ayenera kukhala osabala ndipo adakhazikika asanagwiritse ntchito. Chithandizo cha khoma lamkati ndizakuti, ndiye kuti mafuta a siliva amabalalika mu ether ndi ethanol, ndipo khoma lokutidwa, ndi khoma lokutidwa ndi chubu limauma kapena lophika. Popeza mafuta osakaniza a silinayi ndi chosakaniza kwambiri, ndizosatheka kukhala ndi kulumikizana kwa mankhwalawo ndi galasi, koma kumangotsatira khoma lamkati la chubu choyeserera ndipo imakhala ndi nthawi yotsika. Kuphatikiza apo, mafuta a silina ali ndi mphamvu yokhudza zolengedwa zodziwika bwino za anticoagulant, kotero kuti kuthekera kovuta kwa reagent, chifukwa chovuta. Pakadali pano, njira yabwino kwambiri yothandizirana ndi cobalt 60 yowonetsera madzi owonetsera kuti iwonetsetse kuti zisasunthike kuonetsetsa kuti kusasunthika, kusalala, komanso ayi. Khoma lamkati la malo osungira magazi popanda zowonjezera limakhala ndi silika kuti apewe maselo amwazi kuti asalowe kukhoma ndikutchinjiriza maselo kuti asatayike mu centrifugation. Komabe, kuchokera pakuwona kwachilengedwe ndi chitetezo, machubu otolera magazi opangidwa ndi pulasitiki ndi olefukira komanso osavuta kunyamula, ndipo amatha kuwonongeka pang'onopang'ono, zomwe zingachitike posankha ya vacuum Masamba osungira machubu.

Chotseka cha sealant: Ubwino wa kuyika kwanyanja kumakhudzanso ntchito ya kuphika kwa magazi a chubu choyambirira cha magazi. Ndikulimbikitsidwa kugwiritsa ntchito race mphira m'malo mwa mphira wachilengedwe. Mafilimu achilengedwe a mphira ali ndi zowonjezera kwambiri ndipo ndi mtundu wa zinthu zomwe zingayambitse hemolysis. Ambiri opanga mafayilo ndi zowonjezera (kuphatikiza mafuta a paraffin, mafuta a silika, onunkhira, olondera, etc.) adzakwera khoma lagalasi. Zinthu zonga heparin zimakhudza makamaka madzi osungunuka a heparin owuma. Kuphatikiza apo, mawonekedwe ake amlengalenga samakumananso ndi zofunikira za chubu cha vacuum, kutayika kwa vacuum kuli kovuta, ndipo kulumikizana kwa pulagi kumatha kuwona kuti pulagi ikusunthira kukhoma. Nkhole ya Nyama ili ndi chikopa chabwino, ndipo zinthu zosungunuka zimachepetsedwa kwambiri, kotero kuti posungira a chubu nthawi zonse amatha kukhalabe ndi vuto la miyezi 24 iliyonse mpaka kusokonezeka kwa 101.3 kpa. Kutchinga kosalekeza kumathandizira kuti kusonkhanitsa magazi kukhalebe ndi kusintha kwa magazi ngakhale pali kusiyana kwa magazi komanso kusinthika kwa magazi, komanso cholakwika chosungira magazi chikhoza kukhala olamulidwa mkati mwa ± 5%. Gwero la cholakwika makamaka kusintha kwa magazi magazi ndi cholakwika changozi, ndipo dzanja linalo ndi kusiyana pang'ono m'mimba mwa chubu choyeserera. Machubu amakono osungira magazi amapangira machubu ambiri amapangidwa ndi zipewa zowonjezera kawiri. Chosanjikiza mkati mwa pulagi yofewa yolumikizidwa ndi mafuta zimakutidwa ndi chivundikiro cha pulasitiki, chomwe chimapangitsa kuti zikhale zosavuta kutsegula, ndipo njira yake yotsegulira mbali imalepheretsa magazi kukhala owaza. Mapangidwe owoneka ngati mbiya agalasi amapanga chivundikiro chokhazikika, ndipo gawo lokhazikika pamwamba pa chivundikiro limatha kupewa kulumikizana ndi zitsanzo zamagazi ndikuchepetsa kuipitsidwa kwa magazi kwa ogwiritsa ntchito. Kugwiritsa ntchito chubu chosungira magazi kumadziwika ndi mtundu wovomerezeka wa mutu, womwe ndi wowoneka bwino komanso wosavuta kusiyanitsa, kupewa kugwiritsa ntchito zowonjezera zolakwika m'magazi ndipo kusagwirizana kwa zitsanzo zomwe zimatumizidwa kuti zisayang'anire. zinthu zoyeserera.
