Virusi zo mu kirere: Uruhare rwa masike ya N95 yapimwe neza na filteri ya HEPA

Kuva icyorezo cya COVID-19 cyatangira hashize imyaka irenga 2, 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, Monash University Monash Health Medicine Umushakashatsi Ukomeye hamwe na Monash Health Respiratory and Medicine Medicine Sleep, ubushakashatsi bwari bufite intego ebyiri nyamukuru.
Iya mbere ni "kugereranya urugero abantu banduye na aerosole ya virusi mugihe bambaye ubwoko butandukanye bwa mask kimwe ninkinzo zo mumaso, amakanzu na gants".
Kubushakashatsi, itsinda ryapimye uburinzi butangwa na masike yo kubaga, masike ya N95, hamwe na masike ya N95.
Maskike yo kubaga inshuro imwe irinda uwambaye ibitonyanga binini. Ifasha kandi kurinda umurwayi guhumeka.
Mask 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 zose hamwe nibirango bya masike ya N95 bikwiranye nabantu bose.Ubuyobozi bukuru bw’umutekano n’ubuzima muri Amerika (OSHA) butanga gahunda yo gupima neza aho abakoresha bafasha abakozi babo kumenya masike ya N95 itanga uburinzi cyane.
Mask ya N95 yapimwe neza igomba guhuza neza, amaherezo igatanga "kashe" hagati yuruhande rwa 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 birinda umuntu kurinda uwambaye kwanduza virusi ya aerosol.
Akayunguruzo keza cyane (HEPA) muyungurura ikuraho 99,97% yibice byose byo mu kirere 0.3 micron.
Kubushakashatsi, Dr. Joosten nitsinda rye bashyize umukozi wubuzima, nawe wagize uruhare mubushakashatsi, mubyumba byubuvuzi bifunze muminota 40.
Igihe bari mucyumba, abitabiriye amahugurwa bambaraga PPE, harimo uturindantoki, ikanzu, ingabo yo mu maso, hamwe na bumwe mu buryo butatu bwa masike - kubaga, N95, cyangwa kwipimisha N95. Mu bizamini byo kugenzura, ntibigeze bambara PPE, nta nubwo bambaye masike.
Abashakashatsi berekanye abakozi bashinzwe ubuzima kuri verisiyo ya fage ya PhiX174, virusi y’icyitegererezo itagira ingaruka yakoreshejwe muri ubwo bushakashatsi kubera genome ntoya.Abashakashatsi bahise basubiramo ubwo bushakashatsi bakoresheje sisitemu yo kuyungurura HEPA mu cyumba cy’amavuriro gifunze.
Nyuma ya buri bushakashatsi, abashakashatsi bavanye uruhu ahantu hatandukanye kumubiri wumukozi wubuzima, harimo uruhu munsi ya mask, imbere yizuru, nuruhu kumaboko, ijosi no mu gahanga. Ubushakashatsi bwakorewe inshuro 5 hejuru ya 5 iminsi.
Nyuma yo gusesengura ibyavuyemo, Dr. Joosten n'itsinda rye basanze iyo abakozi bashinzwe ubuzima bambaye masike yo kubaga hamwe na masike ya N95, bafite virusi nyinshi mu maso no mu mazuru.Basanze imitwaro ya virusi yari mike cyane iyo bipimishije N95. bari bambaye.
Byongeye kandi, itsinda ryasanze guhuza kwaAkayunguruzo ka HEPA, bipimishije neza masike ya N95, gants, amakanzu hamwe ninkinzo zo mumaso byagabanije virusi kugeza kurwego rwa zeru.
Muganga Joosten yizera ko ibyavuye muri ubu bushakashatsi bifasha kwemeza akamaro ko guhuza ubuhumekero bwa N95 bwapimwe neza hamwe na filtre ya HEPA kubakozi bashinzwe ubuzima.
Yabisobanuye agira ati: “Byerekana ko iyo uhujwe na filteri ya HEPA (guhanahana 13 mu kirere mu isaha), gutsinda ikizamini cya N95′s birashobora kurinda virusi nyinshi za virusi.”
Ati: “[Kandi] byerekana ko uburyo butandukanye bwo kurinda abakozi bashinzwe ubuzima ari ngombwa kandi ko kuyungurura HEPA bishobora guteza imbere umutekano w'abakozi bashinzwe ubuzima.”
MNT kandi yaganiriye na Dr. Fady Youssef, impuguke mu bijyanye na pulmonologue, umuganga akaba n'inzobere mu kwita ku kigo nderabuzima 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 ya masike ya N95 bisaba kwipimisha byihariye - ntabwo ari kimwe gusa.” Maska ni nziza nk'uko ihuye mu maso.Niba wambaye mask idakwiranye, ntacyo ikora kugirango ikurinde. ”
Kubyerekeye kongeramobyoroshye HEPA kuyungurura, Dr. Youssef yavuze ko iyo ingamba zombi zoroheje zikorana, byumvikana ko hazabaho ubufatanye bukomeye ningaruka zikomeye.
Yongeyeho ati: “[Yongeyeho ibindi bimenyetso […] kugira ngo harebwe niba hari ingamba nyinshi zo kugabanya uburyo bwo kwita ku barwayi bafite indwara zo mu kirere kugira ngo bagabanye kandi twizere ko izakuraho ingaruka ku bakozi bashinzwe ubuzima babitaho.”
Abahanga mu bya siyansi bifashishije amashusho 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.
