Udupfukamunwa dusanzwe tugizwe na: udupfukamunwa tw'ipamba,udupfukamunwa dukoreshwa rimwe(urugero, udupfukamunwa two kubaga, udupfukamunwa two kubaga), n'udupfukamunwa two kwirinda kwa muganga (udupfukamunwa twa N95/KN95).
Muri byo, udupfukamunwa two kwirinda indwara (udupfukamunwa twa N95/KN95) n'udupfukamunwa two kubaga twombi ni imiti ya leta yagenzuwe na SARS mu 2003, kandi ifite inshingano zo kubuza amazi n'ibitonyanga kwinjira. Iyo twambaye neza, dushobora gukumira indwara ziterwa n'ibitonyanga. Ni yo mahitamo yacu ya mbere ya mask.
N95 si izina ryihariye ry'igicuruzwa. Igicuruzwa cyujuje ibisabwa na N95 kandi cyemewe na NIOSH gishobora kwitwa mask ya N95.
Mu Bushinwa, udupfukamunwa twa K95 twerekana ubwoko bw'udupfukamunwa tudakoresha amavuta hakurikijwe ibipimo ngenderwaho by'igihugu cy'Ubushinwa bya GB2626-2006. Icyiciro cya KN gikwiriye kuyungurura udupfukamunwa tudakoresha amavuta. Igice cy'ikoranabuhanga cy'ibihugu byombi gifite ibipimo bimwe. 95 yerekeza ku buryo bwo kuyungurura ≥95%.
Ukurikije uburyo mikorobe zikoreshwa, amahitamo meza ni uburyo bwo guhumeka bukoresha uburyo bwo guhumeka bukoresha uburyo bwo guhumeka (N95/KN95 respirateur)
Udupfukamunwa two kwa muganga tugomba kuba twujuje ibipimo ngenderwaho bya GB 19083-2010 by’Ubushinwa hamwe n’ubushobozi bwo kuyungurura ≥95% (hakoreshejwe ikizamini cy’ibintu bitari amavuta). Ni ngombwa gutsinda ikizamini cyo kwinjira mu maraso (kugira ngo wirinde ko amazi asohoka mu mubiri) no kubahiriza ibimenyetso bya mikorobe.
Udupfukamunwa two kubaga dukunze gukoreshwa mu byumba byo kubaga no mu bindi bice aho hari ibyago byo kwibasira amazi n'amaraso. Dushobora kubuza amaraso n'amazi yo mu mubiri kwinjira muri utwo dupfukamunwa no kwanduza uwatwambaye. Hagati aho, dufite ubushobozi bwo kuyungurura burenga 95% ku bagiteri.
Virusi ni utunyangingo duto cyane dushobora kubona buri munsi. Tuzi neza PM2.5, yerekeza ku tunyangingo dufite ingano ya mikoroni 2.5 cyangwa munsi yayo, mu gihe ingano ya virusi iri hagati ya mikoroni 0.02 na 0.3. Virusi ni nto cyane, ntabwo ari akaga?
Ni imyumvire isanzwe ko agapfukamunwa ari agapfukamunwa, ko uduce duto ugereranije n'umwobo w'agapfukamunwa dushobora kunyuramo, kandi ko uduce duto ugereranije n'umwobo w'agapfukamunwa tuba twazibye. Mu by'ukuri, ubwoko bwiza cyane bwa agapfukamunwa ka N95 ni hagati y'uduce tunini n'uduce duto cyane.
Nubwo agapfukamunwa gakingira umubiri gafite uburinzi bwo hejuru gafite ingaruka nziza ku burinzi, gafite ubushobozi bwo guhangana n’ubuhumekero bwinshi bitewe n’uburyo bwinshi bwo kuyungurura, gukomera neza, no kwambara igihe kirekire byongera umutwaro wo guhumeka kandi bigatera ibibazo byo guhumeka n’ibindi bibazo by’ubuhumekero.
Iyo ikoreshwa buri munsi gusa kandi ntujye ahantu hafite ibyago byinshi byo kwandura indwara, nko mu bitaro, ushobora guhitamo agapfukamunwa ko kubaga.
Uretse guhitamo agapfukamunwa gakwiye, ugomba no gukoresha gakwiye, kandi ukitondera uburyo bwo kwambara n'igihe cyo gukoresha. Soma witonze uburyo buri ku gapaki, kandi wemeze ko umwuka ufunganye nyuma yo kwambara. Niba wambaye indorerwamo kandi igihu kikagaragara kuri lens, bigomba kuba ari ukoagapfukamunwantabwo yambaye neza.
