Katswiri wazachipatala Gauze ndi mankhwala ochizirachiritsa mankhwalawa, ndikuteteza bwino swab.

Pazinthu zopanga zamankhwala zopangira swab, "alkali otentha" a gauze ndi njira yofunika kwambiri. Cholinga ndikuchotsa kusalala, mafuta ndi sera mu nsalu ya imvi, zomwe zimakhudza mwachindunji ndi zamankhwala. Nthawi yomweyo, pali zodetsa zambiri zopangidwa mwanjira imeneyi, zomwe zimafunikira chisamaliro chapadera pantchito.

Pofuna kuchepetsa kuchuluka kwa zodetsa zomwe zatulutsidwa mu kupanga swab, nsalu yofiyira yomwe imapangidwa nthawi zambiri imathamangitsidwa, kutsuka kwamadzi ndikuchotsa ma cylinder mu silinda yotentha kwambiri. Zonyansa zomwe zidachitika m'mbuyomu zimabweretsedwa gawo lotsatira kuti muwonetsetse kuti wotanulirayo amakwaniritsa miyezo yofunikira komanso mtundu wazogulitsa, madzi oyera ayenera kugwiritsidwa ntchito poyeretsa.

Kuphatikiza apo, kugwiritsidwa ntchito kwachipatala kuyenera kuyesedwa mosamalitsa musanachoke fakitale. Imakhala ndi kumverera kofewa kwa dzanja, manyowa olimba m'madzi, ma yunifolomu amatulutsa kachulukidwe, yoyera komanso yopanda pake, yopanda alkali, ndipo ndiotetezeka kugwiritsa ntchito. Kusankhidwa kwapadera kwa thonje. Pambuyo posankha woyenerera komanso woyenera, umayang'aniridwa ndi chlorine oxygen bution wofukitsira kawiri (ndipo kenako nsalu yopukutira) imagawika m'madzi, kenako ndikudula m'mankhwala ofunikira.
