Kuva icyorezo cya COVID-19 cyatangira mu myaka irenga 2 ishize, ubuhumekero bwa N95 bwagize uruhare runini mubikoresho byokwirinda (PPE) byabakozi bashinzwe ubuzima ku isi.
Ubushakashatsi bwakozwe mu 1998 bwerekanye ko Ikigo cy’igihugu gishinzwe umutekano n’ubuzima (NIOSH) cyemejwe na mask ya N95 cyashoboye gushungura 95 ku ijana by’ibice byo mu kirere, nubwo bitigeze bimenya virusi.Nyamara, ubushakashatsi buherutse gukorwa bwerekanye ko bikwiye a mask igena ubushobozi bwayo bwo kuyungurura ibice byo mu kirere.
Ubu, itsinda ry’ubushakashatsi ryaturutse muri kaminuza ya Monash muri Ositaraliya rivuga ko masike ya N95 yapimwe neza hamwe na sisitemu yo kuyungurura HEPA itanga uburyo bwiza bwo kwirinda virusi zandurira mu kirere.
Nk’uko byatangajwe n'umwanditsi mukuru Dr Simon Joosten, Ubuvuzi bw’ubuzima bwa kaminuza ya Monash muri kaminuza ya Monash, Umushakashatsi mukuru w’ubushakashatsi hamwe na Monash Health Respiratory hamwe n’umuganga w’ubuvuzi bw’ibitotsi, ubushakashatsi bwari bufite intego ebyiri nyamukuru.
Iya mbere ni "kugereranya urugero abantu banduye na aerosole ya virusi mugihe bambaye ubwoko butandukanye bwa masike kimwe n'ingabo zo mumaso, amakanzu na gants".
Kubushakashatsi, itsinda ryapimye uburinzi butangwa na masike yo kubaga, masike ya N95, hamwe na masike ya N95 yapimwe neza.
Maskike zo kubaga zikoreshwa zirinda uwambaye ibitonyanga binini.Bifasha kandi kurinda umurwayi guhumeka.
Masike ya N95 ihuza isura neza kuruta masike yo kubaga.Bifasha kurinda uwambaye guhumeka mu bice bito byo mu kirere bya aerosol, nka virusi.
Kuberako isura ya buriwese itandukanye, ntabwo ingano n'ibirango bya masike ya N95 bibereye buriwese.Ubuyobozi bushinzwe umutekano n’ubuzima muri Amerika (OSHA) butanga gahunda yo kwipimisha neza aho abakoresha bafasha abakozi babo kumenya masike ya N95 itanga uburinzi cyane.
Mask ya N95 yapimwe neza igomba guhura neza, amaherezo igatanga "kashe" hagati yinkombe ya mask no mumaso yuwambaye.
Muganga Joosten yabwiye MNT ko usibye gupima masike atandukanye, itsinda ryashakaga kumenya niba ikoreshwa rya filteri ya HEPA ishobora kuzamura inyungu z’ibikoresho bikingira umuntu kugira ngo birinde uwambaye kwanduza virusi ya aerosol.
Akayunguruzo keza cyane (HEPA) muyunguruzi ikuraho 99,97% yibice byose byo mu kirere 0.3 microne mubunini.
Kubushakashatsi, Dr. Joosten nitsinda rye bashyize umukozi wubuzima, nawe wagize uruhare mubushakashatsi, mubyumba byubuvuzi bifunze muminota 40.
Mugihe bari mucyumba, abitabiriye amahugurwa bambaraga PPE, harimo udukariso, ikanzu, ingabo yo mu maso, hamwe na bumwe mu bwoko butatu bwa masike - kubaga, N95, cyangwa N9 yipimishije neza. Mu bizamini byo kugenzura, ntibigeze bambara PPE, nta nubwo bambaye masike.
Abashakashatsi berekanye abakozi b’ubuzima kuri verisiyo ya fage ya PhiX174, virusi y’icyitegererezo itagira ingaruka yakoreshejwe mu bushakashatsi kubera genome ntoya.Abashakashatsi bahise basubiramo ubwo bushakashatsi bakoresheje uburyo bworoshye bwo kuyungurura HEPA mu cyumba cy’amavuriro gifunze.
Nyuma ya buri bushakashatsi, abashakashatsi bavanye uruhu ahantu hatandukanye ku mubiri w’ubuzima, harimo uruhu ruri munsi ya mask, imbere yizuru, ndetse nuruhu ku kuboko, ijosi no mu gahanga. Ubushakashatsi bwakozwe inshuro 5 hejuru ya 5 iminsi.
Nyuma yo gusesengura ibyavuyemo, Dr. Joosten n'itsinda rye basanze ko igihe abashinzwe ubuzima bambara masike yo kubaga hamwe na masike ya N95, bafite virusi nyinshi mu maso no mu mazuru.Basanze imitwaro ya virusi yari hasi cyane iyo masike ya N95 yapimwe neza. bari bambaye.
Byongeye kandi, itsinda ryasanze guhuza kwaAkayunguruzo ka HEPA, bipimishije neza masike ya N95, gants, amakanzu hamwe ninkinzo zo mumaso byagabanije virusi kugera kurwego rwa zeru.
Muganga Joosten yizera ko ibyavuye muri ubu bushakashatsi bifasha kwemeza akamaro ko guhuza imyuka ihumeka ya N95 yapimwe neza hamwe na HEPA iyungurura abakozi bashinzwe ubuzima.
Yabisobanuye agira ati: “Byerekana ko iyo uhujwe na filteri ya HEPA (guhanahana ikirere 13 mu isaha), gutsinda ikizamini cya N95′s birashobora kurinda virusi nyinshi za virusi.”
Ati: “[Kandi] byerekana ko uburyo butandukanye bwo kurengera abakozi bashinzwe ubuzima ari ngombwa kandi ko kuyungurura HEPA bishobora kongera umutekano ku bakozi bashinzwe ubuzima muri ibi bihe.”
MNT kandi yaganiriye na Dr. Fady Youssef, impuguke mu bijyanye n’ibihaha, umuganga n’inzobere mu kwita ku barwayi bo mu kigo cy’ubuvuzi cya MemorialCare Long Beach i Long Beach, muri Californiya, ku bijyanye n’ubushakashatsi. Yavuze ko ubushakashatsi bwemeje akamaro ko kwipimisha.
Dr. Youssef yabisobanuye agira ati: “Ibirango bitandukanye hamwe na moderi zitandukanye za masike ya N95 bisaba kwipimisha byihariye - ntabwo ari kimwe gusa.”Niba wambaye mask itagukwiriye, ntacyo ikora kugirango ikurinde. ”
Kubyerekeye kongerwahobyoroshye HEPA kuyungurura, Dr. Youssef yavuze ko iyo ingamba zombi zo kugabanya ubukana zikoranye, byumvikana ko hazabaho ubufatanye bukomeye n'ingaruka zikomeye.
Yongeyeho ati: “[Yongeyeho ibindi bimenyetso […] kugira ngo harebwe niba hari ingamba nyinshi zo kugabanya ingamba zo kugabanya abarwayi bafite indwara zo mu kirere kugira ngo bagabanye kandi twizere ko izakuraho ingaruka ku bakozi bashinzwe ubuzima babitaho.”
Abahanga mu bya siyansi bakoresheje laser iyerekwa kugira ngo basuzume ubwoko bw'ingabo zo mu rugo ari nziza mu kwirinda kwanduza umwuka…
Ibimenyetso nyamukuru bya COVID-19 ni umuriro, inkorora yumye no guhumeka neza. Wige byinshi kubindi bimenyetso nibisubizo byateganijwe hano.
Virusi ziri hafi ya hose, kandi zirashobora kwanduza ibinyabuzima byose. Hano, wige byinshi kuri virusi, uko bikora, nuburyo bwo kurindwa.
Virusi nka roman coronavirus zirandura cyane, ariko hariho intambwe nyinshi ibigo n'abantu ku giti cyabo bashobora gutera kugirango bagabanye ikwirakwizwa rya virusi.
