Kulowetsedwa Ndi Kuthira Magazi

Kulowetsedwa ndi kuthiridwa magazi kwa PVC ndi zida zopangidwa mwapadera zomwe zimagwiritsidwa ntchito popanga zida zamankhwala monga matumba a IV ndi machubu. PVC (polyvinyl chloride) ndi thermoplastic yosunthika yomwe imapereka maubwino angapo pakugwiritsa ntchito izi.Kuthira ndi kuthiridwa magazi PVC mankhwala apangidwa kuti akwaniritse miyezo yolimba yachipatala, kuwonetsetsa kuti biocompatibility ndi chitetezo chogwiritsidwa ntchito pokhudzana ndi magazi ndi madzi amunthu. Mankhwalawa nthawi zambiri amapangidwa ndi mapulasitiki kuti azitha kusinthasintha komanso kufewa, kotero amatha kusinthidwa mosavuta ndikugwirizanitsidwa ndi zipangizo zachipatala.Mapangidwe a PVC omwe amagwiritsidwa ntchito polowetsedwa ndi kuikidwa magazi amapangidwanso kuti asagwirizane ndi mankhwala omwe amapezeka kawirikawiri m'magulu azachipatala, monga mankhwala ndi oyeretsa. Amapangidwa kuti azikhala ndi zotchinga zabwino, kuonetsetsa kuti zinthu zomwe zimaperekedwa kwa odwala zimakhala bwino mkati mwa matumba kapena tubing.Kuonjezera apo, kulowetsedwa ndi kuikidwa kwa PVC mankhwala nthawi zambiri amapangidwa ndi zowonjezera zomwe zimapereka kukana kwa UV ndi antimicrobial katundu kuti ateteze kukula kwa mabakiteriya pamwamba pa zipangizo zamankhwala. Izi zimathandiza kuchepetsa chiopsezo cha kuipitsidwa panthawi ya kuikidwa magazi kapena kuyendetsa mankhwala.Ndikofunikira kuzindikira kuti ngakhale kuti mankhwala a PVC akhala akugwiritsidwa ntchito kwambiri pazachipatala kwa zaka zambiri, pali nkhawa zomwe zimapitirizabe kutulutsa zinthu zovulaza monga phthalates panthawi yopanga ndi kugwiritsa ntchito zipangizo zachipatala za PVC. Opanga akugwira ntchito mosalekeza kuti apeze zida zina zothana ndi nkhawazi. Ponseponse, kulowetsedwa ndi kuthiridwa magazi mankhwala a PVC amagwira ntchito yofunika kwambiri pazachipatala popereka zida zotetezeka komanso zodalirika zopangira matumba a IV ndi machubu. Mankhwalawa amapereka machitidwe abwino kwambiri ndipo amapangidwa kuti akwaniritse zofunikira zachipatala.
