PVA Siponji Chiyambi

Polyvinyl mowa kalasi yachipatala microporous siponji ndi mtundu wa zinthu polima ndi ntchito bwino kuyamwa ndi pamwamba kwambiri ofewa pokhudzana ndi thupi la munthu, amene akhoza kuonongeka kwathunthu mwachibadwa.Kuchita kwake kwabwino koyamwa sikumangothamanga msanga, komanso kumawonekeranso mu chiŵerengero chake chapamwamba kwambiri.Nthawi zonse, gilamu imodzi ya siponji ya PAV imatha kuyamwa kuwirikiza kasanu ndi kawiri madzi a m'thupi mwake.Choncho, mtundu uwu wa zinthu chimagwiritsidwa ntchito masiku opaleshoni opaleshoni m`malo kuyamwa thonje ndi yopyapyala defatted, ndipo chimagwiritsidwa ntchito pa mayiko opaleshoni opaleshoni.
Polyvinyl alcohol-grade macroporous sponge suction fluid imagwira ntchito bwino kwambiri, imatsegula kwambiri, imakhala yolimba kwambiri, komanso yofewa kwambiri ikakumana ndi thupi la munthu.Amagwiritsidwa ntchito kwambiri pakuchita opaleshoni yachipatala, makamaka pankhani ya kutulutsa mpweya woipa.Masiponji otaya zinyalala amatha kuonongeka mwachilengedwe ndipo sizingayambitse mavuto oyipitsa chilengedwe.Nthawi zambiri, gramu imodzi ya siponji ya PAV macroporous popanda zowonjezera imatha kuyamwa kuwirikiza kasanu ndi kamodzi madzimadzi ake amthupi.Zinthu zamtunduwu zimagwiritsidwa ntchito m'malo mwa thonje loyamwa komanso chopyapyala mu opaleshoni ya opaleshoni, yomwe imatha kuthana ndi vuto lomwe thonje loyamwa kapena lopyapyala liyenera kusinthidwa nthawi zonse pachipatala.
Siponji ya mowa wa polyvinyl imapangidwa ndi unyolo wa molekyulu wa polyvinyl mowa wochiritsidwa ndi wolumikizira, wopanda ulusi wa ulusi kapena mutu wa ulusi, ndipo sipadzakhala ulusi womwe umatha kugwiritsidwa ntchito.Panthawi ya opaleshoni ya maso, makutu, mphuno ndi mmero, craniotomy ya ubongo wa ubongo ndi opaleshoni ya mtima ya thoracic, sizimakhudza machiritso a bala chifukwa cha kukhetsa kwa ulusi.Malinga ndi ntchito zosiyanasiyana zachipatala, ngati zothandizira zoyenera zatsitsidwa mu siponji, zitha kulimbikitsanso kuchira kwa bala.Panthawi imodzimodziyo, siponji imakhala ndi makina abwino ndipo imatha kusinthidwa kukhala mawonekedwe osiyanasiyana malinga ndi zosowa zosiyanasiyana za opaleshoni.Siponji yoyamwa magazi kapena ndodo yooneka ngati mkondo yomwe imagwiritsidwa ntchito makamaka popanga ma microsurgery, yomwe imatha kuyamwa mwachangu magazi osawoneka bwino ndikuwonetsetsa kuti opaleshoniyo ndi yolondola.
Pindani sinthani gawoli njira
Pali makamaka njira yotulutsa thovu, tsitsi lotulutsa thovu lamankhwala komanso kuphatikiza kwathupi ndi mankhwala kwa njira zitatu zochitira thovu.Koma pakadali pano, ukadaulo wopanga wa PVA siponji absorbent imagwiritsa ntchito njira yakumbuyo yodzaza thovu.Ndiko kuti, wowuma amayamba kudzazidwa mu yankho la PVA pa kutentha koyenera, ndiyeno wowuma amatsukidwa pambuyo poti PVA ilumikizidwa ndikukhazikika pa kutentha kwina.Njirayi ikagwiritsidwa ntchito popanga, kuipitsidwa kwa chilengedwe kumakhala koopsa, njira yotsatirira yotsatiridwa ndi yayitali, wowuma sungathe kutsukidwa kwathunthu, ndipo chothandizira cha wowuma ndi asidi sichingasinthidwenso, zomwe sizingathandize kupulumutsa chuma. ndi kuchepetsa ndalama.
