Chowumitsa chachipatala ndi chipangizo chomwe chimagwiritsa ntchito kutentha, mankhwala, kapena ma radiation kuti aphe kapena kuchotsa mitundu yonse ya tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda kuchokera ku zipangizo zamankhwala ndi zida.Ndi chida chofunikira pazachipatala chilichonse, chifukwa chimathandiza kupewa kufalikira kwa matenda ndi matenda.Njira yotseketsa imatsimikiziranso kuti zida zachipatala ndizotetezeka kuti zigwiritsidwe ntchito kwa odwala.Ma sterilizers azachipatala amabwera m'mitundu yosiyanasiyana, kuphatikiza ma autoclaves, zowumitsa mankhwala, ndi zowumitsa ma radiation.Ma autoclaves amagwiritsa ntchito nthunzi ndi kukakamiza kuti asaphetse zida, pomwe zowumitsa mankhwala zimagwiritsa ntchito mankhwala monga ethylene oxide.Mankhwala ophera tizilombo amagwiritsa ntchito cheza cha ionizing kupha tizilombo toyambitsa matenda.Ma sterilizers azachipatala amafunikira chisamaliro choyenera ndikuwunika kuti atsimikizire kuti akugwirabe ntchito.
