Kuvulala khungu kokha ndi vuto lodziwika bwino pazochitika zamankhwala. Nthawi zambiri zimachitika pamagulu akhungu owonekera monga miyendo ndi nkhope. Mabala a zipsinjo zamtunduwu nthawi zambiri amakhala osakhazikika komanso opatsirana mosavuta, ndipo ziwalo zina zolumikizirana sizivuta kuzimanga. Mavalidwe azizolowezi amasintha mayendedwe olimba azachipatala ndizovuta. Pakadali pano, yankho labwino kwambiri pochiza matenda amtunduwu ndikugwiritsa ntchito njira yolumikizira mabala ngati njira yatsopano yothandizira kapena zinthu zothandizira. Mavalidwe amtundu uwu ndi zokutira zokutira zopangidwa ndi ma polima amadzimadzi (kuvala kwamabala pakampani yathu kumagwiritsa ntchito zida za silicon zofananira ndi 3M). Pambuyo poti agwiritsidwe ntchito pamabala abodza amthupi, kanema woteteza wokhala ndi kulimba kwakanthawi ndikumangika akhoza kupangidwa. Kanema woteteza amachepetsa kusungunuka kwamadzi, kumawonjezera kutsekemera kwa minofu ya mabala, ndikupanga malo amadzimadzi ochiritsa olimbikitsa kuchiritsa kwa zilonda ndikupewa matenda.
Mfundo yayikulu yogwiritsira ntchito bandeji yamadzi ndikutsegula chilondacho ndi filimu yosinthasintha, yolimba, komanso yopumira. Pangani malo osungira madzi, mpweya wotsika, komanso malo okhala ndi acidic pang'ono pakati pa kavalidwe ndi bala kuti muchepetse kukula kwa mabakiteriya pachilondacho. Limbikitsani kaphatikizidwe ka ma fibroblast ndikulimbikitsa kufalikira kwa mitsempha, kuti isatulutse zibalabala, kulimbikitsa machiritso abodza, ndikukonzanso kansalu mwachangu. Zimagwirizana ndi mfundo zamankhwala amachiritso am'madzi amakono pamavuto. Kuphatikiza apo, zida zopangidwa ndi silicon zimagwiritsidwa ntchito ngati zokutira piritsi komanso zida zopangira makanema, zomwe sizimayamwa, zilibe kagayidwe kabwino ka kagayidwe, komanso zimakhala ndi biocompatibility yayikulu. Poyerekeza ndi mavalidwe olimba achikhalidwe, nkovuta kutsatira malondawo kuti mupewe kuvulala kwachiwiri pachilondacho. Chifukwa chake, bandeji yamadzi yamtunduwu ndiyotetezeka komanso yothandiza kutetezera zilonda zapakhungu (monga mabala, kutumbuka, kumva kuwawa, ndi mabala kumapeto kwa suture).
