Momwe mungasankhire chigoba chosalukidwa | JINHAOCHENG

Zophimba nkhope zodziwika bwino zimaphatikizapo: zophimba nkhope za thonje,zophimba nkhope zotayidwa(monga, zophimba nkhope za opaleshoni, zophimba nkhope za opaleshoni), ndi zophimba nkhope zachipatala (zophimba nkhope za N95/KN95).

Pakati pawo, masks oteteza ku matenda (masks a N95/KN95) ndi masks ochitira opaleshoni ndi zinthu zachipatala zomwe boma lakhala likuzilamulira kuyambira SARS mu 2003, ndipo ntchito yake ndi kuletsa madzi ndi madontho kuti asalowe. Ngati atavalidwa bwino, amatha kupewa matenda opatsirana ndi madontho. Ndi chisankho chathu choyamba cha masks.

N95 si dzina lenileni la chinthucho. Chinthu chomwe chikukwaniritsa muyezo wa N95 ndipo chavomerezedwa ndi NIOSH chingatchedwe chigoba cha N95.

Ku China, masks a K95 amatanthauza gulu la masks a tinthu tating'onoting'ono topanda mafuta malinga ndi muyezo wa dziko la China wa GB2626-2006. Kalasi ya KN ndi yoyenera kusefa tinthu tating'onoting'ono topanda mafuta. Gawo la digito la mayiko awiriwa lili ndi muyezo womwewo. 95 imatanthauza kusefa bwino ≥95%.

Kuchokera ku lingaliro la zamoyo, chisankho chabwino kwambiri ndi chopumira chamankhwala chogwirizana ndi valavu yopumira (chopumira cha N95/KN95)

Zophimba nkhope zachipatala ziyenera kukwaniritsa muyezo wa Chinese GB 19083-2010 wokhala ndi mphamvu zosefera ≥95% (pogwiritsa ntchito mayeso osakhala amafuta). Zimafunika kuti munthu apambane mayeso opangidwa kuti alowe m'magazi (kuti aletse madzi amthupi kuti asatuluke) komanso kuti akwaniritse zizindikiro za tizilombo toyambitsa matenda.

Zophimba nkhope za opaleshoni zimagwiritsidwa ntchito kwambiri m'zipinda zochitira opaleshoni ndi malo ena komwe kuli chiopsezo cha madzi ndi magazi kulowa m'thupi. Zingathe kuletsa magazi ndi madzi amthupi kuti asadutse m'zophimba nkhopezo ndikuipitsa wovala. Pakadali pano, zimatha kusefa mabakiteriya ndi mphamvu yoposa 95%.

Mavairasi ndi tinthu tating'ono kwambiri tomwe timapeza tsiku ndi tsiku. Tikudziwa bwino za PM2.5, yomwe imatanthauza tinthu tating'onoting'ono tomwe tili ndi kukula kwa tinthu tating'onoting'ono tokwana ma microns 2.5 kapena kuchepera, pomwe kukula kwa tinthu ta mavairasi kumayambira pa 0.02 mpaka 0.3 microns. Kachiromboka ndi kakang'ono kwambiri, sikoopsa?

Ndi malingaliro olakwika ofala kuti chigoba ndi sefa, kuti tinthu tating'onoting'ono kuposa dzenje la sefa tingadutse, ndi kuti tinthu tating'onoting'ono kuposa dzenje la sefa timatsekedwa. Ndipotu, mtundu wabwino kwambiri wa zigoba za N95 ndi pakati pa tinthu tating'onoting'ono ndi tinthu tating'ono kwambiri.

Ngakhale chigoba choteteza chachipatala chokhala ndi chitetezo chapamwamba chimakhala ndi chitetezo chabwino, chimakhala ndi mphamvu yolimba yopumira chifukwa cha kuchuluka kwa zinthu zosefera, kulimba bwino, komanso kuvala kwa nthawi yayitali kumawonjezera mphamvu yopumira ndikuyambitsa mavuto opumira komanso kusasangalala kwina.

Ngati imagwiritsidwa ntchito tsiku ndi tsiku lokha ndipo simukupita kumalo omwe ali ndi chiopsezo chachikulu cha matenda opatsirana, monga zipatala, mungasankhe chigoba cha opaleshoni.

Kuwonjezera pa kusankha chigoba choyenera, muyeneranso kugwiritsa ntchito choyenera, ndipo samalani ndi momwe mungavalire komanso nthawi yogwiritsira ntchito. Werengani mosamala momwe zilili pa phukusi, ndipo tsimikizirani kuti mpweya suli bwino mukatha kuvala. Ngati muvala magalasi ndipo utsi umawonekera pa lenzi, ziyenera kukhala chifukwa chakutichigobasakuvala bwino.
