Imbunda y'ivyuma (izwi kandi nk'igikoresho co gutera ivyuma, imbunda y'ivyuma, canke igikoresho co gutera ivyuma) ni igikoresho gikoreshwa n'amaboko canke n'ububasha-gikoreshwa mu gutera ivyuma. Hashingiwe ku buryo bwo gutwara, zigabanwa mu mice itatu: imbunda zikoreshwa n’amaboko, imbunda zikoreshwa n’umuyaga be n’imbunda zikoreshwa n’umuyagankuba. Imbunda zikoreshwa n’umuyaga zisaba isoko y’umuyaga kandi zifise ikintu co guceceka, mu gihe imbunda zikoreshwa n’umuyagankuba zikoreshwa n’amabateri ashobora gusubirwamwo, ivyo bikaba bituma umuntu ashobora gukoresha imirongo 30-45 y’impuzu ku giciro kimwe. Ico gikoresho gikoreshwa cane mu vy’ubwubatsi, mu gushaza, mu vy’imiduga, mu vy’ubuhinga bwa none no mu gupfunyika. Ifasha gupfunyika ivyuma bimwe - nk’ibikoresho vy’ivyuma 310ml/400ml n’ivyuma bifise ishusho y’isosi- (600ml), hamwe n’uguvanga ubwavyo ivyuma vy’ivyuma bibiri (2:1, 4:1 ratio).
Imbunda zikoresha amavuta ashushe zitanga amavuta mu kuyishushanya no kuyishonga. Imbere yo gukoresha, inkoni y’irangi itegerezwa kwinjizwa maze igashushwa iminota 3-5. Ubushuhe bw'umurongo ni nk'ibipimo 200 . Inyuma yo gukoresha, iyo mbunda ikwiye gushirwa igororotse, umugozi nawo ugasukurwa nk’uko bitegekanijwe. Hariho ibigereranyo bimwe bimwe bifise igikoresho kidatonyanga-, igikoresho co guceceka, n'igikoresho co gucungera urugero rw'uruja n'uruza rw'amazi. Iyo mbunda ifise imbere umutwe wo guvanga ushobora gusubirwamwo. Imbunda y’umuyagankuba ikoresha umugozi w’icuma w’aluminium-ufise igisandugu c’ivyuma vyubatswe -mu kugira ngo ihuze neza. Irinde gukorana n’ibihimba bifise ubushuhe bwinshi mu gihe ukoresha kandi ntukore ahantu hari ubukonje. Ku bijanye n’imbunda zikoreshwa n’umuyagankuba zishobora gusubirwamwo, igihe co gukomeza gushusha ntigikwiye kurenga iminota 15.
