Umzi-mveliso weeseliluhlobo lwesikhongozeli senkcubeko yeseli esenziwe ngemathiriyeli ekrwada ye-polystyrene.Ukuze kuhlangatyezwane neemfuno zokukhula kweeseli, le mveliso eluhlaza kufuneka ihlangabezane neemfuno ezifanelekileyo ze-USP Class VI kwaye uqinisekise ukuba izinto eziluhlaza aziqukethe izinto ezichaphazela ukukhula kweeseli.Ke, kumgangatho we-USP yoDidi VI, zeziphi izinto zovavanyo ekufuneka zidlule kuzo izixhobo ezikrwada?

Ukuhlelwa kwe-United States ye-Pharmacopeia yezinto zonyango yi-6, ukusuka kwi-USP iklasi I ukuya kwi-USP yeklasi ye-VI, kunye ne-USP iklasi ye-VI ibe yibakala eliphezulu.Ngokuhambelana ne-USP-NF General Rules, iiplastiki eziphantsi kovavanyo lwempendulo yebhayoloji ye-vivo ziyakwabelwa kuhlelo lweplastiki yonyango olumiselweyo.Injongo yovavanyo kukuqinisekisa ukuhambelana kwe-biocompatibility yeeplastiki ukuze zisetyenziswe kwizixhobo zonyango, ukufakelwa, kunye nezinye iinkqubo.

Isahluko sama-88 se-USP yoKlasi VI sijongene novavanyo lwe-bioreactivity ye-vivo, ejolise ekuqinisekiseni imiphumo ye-bioreactivity yezinto ezilastiki kwizilwanyana eziphilayo.I-feedstock yefektri yeseli ibandakanya iimfuno ezintathu zokuvavanya: 1. Uvavanyo lwesitofu senkqubo: Isampuli ye-compound ilungiswa ngesicatshulwa esithile (umzekelo, ioli yemifuno), kunye ne-polyethylene glycol isetyenziswe esikhumbeni, i-inhaled, okanye ngomlomo.Uvavanyo lulinganisa ubutyhefu kunye nokucaphuka.2. Uvavanyo lwe-Intradermal: Isampuli edibeneyo ibonakaliswe kwizicubu eziphilayo ezingaphantsi kwe-subcutaneous (ithishu ecetywayo isixhobo sonyango / isixhobo sokunxibelelana).Uvavanyo lulinganisa ubutyhefu kunye nokucaphuka kwendawo.3. Ukufakelwa: Ikhompawundi ifakwe kwi-muscle yesampuli.Uvavanyo lulinganisa ubugwenxa, usulelo kunye nokucaphuka.
