Ese hari itandukaniro riri hagati y'udupfukamunwa dusanzwe dukoreshwa mu gusana n'udupfukamunwa dukoreshwa mu gusana mu buryo bw'ubuvuzi? JINHAOCHENG

Ubwa mbere,udupfukamunwa two kwa mugangaUdupfukamunwa two kwa muganga dukunze gukoreshwa ni udupfukamunwa tudapfukamunwa, udupfukamunwa twa gauze na udupfukamunwa two kurwanya virusi.

1. Agapfukamunwa kadakoreshejwe mu irahure gafite ibice birenga bitatu gashobora gukuramo bagiteri n'umukungugu, kandi ni byiza kandi byizewe gukoresha rimwe, nta ngaruka zo kwandura ubwandu.

2. Udupfukamunwa twa gauze ni ubwoko bw'udupfukamunwa twakoreshejwe igihe cyose. Udupfukamunwa twa Miao dukoreshwa cyane mu rwego rw'ubuvuzi n'ubushakashatsi.

3. Udupfukamunwa two kurwanya virusi dukorwa ahanini mu mwenda utari uwo kuboha ufite agace ka filter hagati. Muri rusange, agace ka filter gakozwe mu mwenda washongeshejwe. Gafite akazi ko gusukura no gusukura.

4. Mu by’ukuri, udupfukamunwa dusanzwe ni duke cyane ugereranije n’udupfukamunwa two kwa muganga mu bikoresho.

Ishingiye ahanini ku mikorere n'ibihe byo gukoresha. Iki gihe cy'imyanda myinshi ituruka ku nganda gituma iterambere rya masks riba umwihariko. Dukurikije ibihe bikenewe n'ibyo abakoresha bakeneye, igabanywa ry'ubutaka rizakomeza gutera imbere no gutera imbere. Bityo, haba mu buvuzi cyangwa mu buryo busanzwe, itandukaniro rishobora kuba imiterere, rishobora kuba uburyo bwo kuyungurura, rishobora kuba rikenewe, rishobora kuba rikenewe mu guhumeka.

Mu gihe habayeho icyorezo gishya cya Coronavirus cy'uyu mwaka, komeza ubikeudupfukamunwa two mu maso.

Hari itandukaniro rinini hagati y'udupfukamunwa n'ubushobozi bwatwo bwo kwirinda

Ese hari itandukaniro riri hagati y'udupfukamunwa dusanzwe dukoreshwa mu gusana n'udupfukamunwa two kwa muganga dukoreshwa mu gusana?

Maske zisanzwe zo gukoreshwa mu gihe cyo gusana n'udupfukamunwa dusanzwe two kwa muganga n'udupfukamunwa two kubaga n'udupfukamunwa two kwa muganga

Udupfukamunwa two kwa muganga: tubereye abakozi b'abaganga n'abandi bakozi bafitanye isano kugira ngo tubarinde indwara zandura zo mu kirere zifite uburinzi bwo hejuru.

Udupfukamunwa two kubaga: uburinzi bw'ibanze ku baganga cyangwa abakozi bafitanye isano, no kurinda ikwirakwira ry'amaraso, amazi yo mu mubiri n'imitobe mu gihe cyo kubagwa;

Agapfukamunwa gasanzwe k’ubuvuzi: ingaruka zo kurinda udukoko dutera indwara si nziza. Gashobora gukoreshwa mu rwego rw’ubuvuzi bwa rimwe mu bidukikije bisanzwe, cyangwa mu kuziba cyangwa kurinda utundi dukoko tutari udukoko dutera indwara nk’intangangabo.

Mu by'ukuri, aya ni amahame y'igihugu, ntabwo ari ibintu bitunguranye

(1) Udupfukamunwa two kwa muganga

Dukurikije amahame ya gb19083-2003 "Ibisabwa mu buhanga ku mapfukamunwa yo kurinda ubuvuzi", ibipimo by'ingenzi bya tekiniki birimo ubushobozi bwo kuyungurura uduce tudakoresha amavuta ndetse no kudakoresha umwuka unyura:

1. Uburyo bwo kuyungurura: Uburyo bwo kuyungurura bw'umurambararo w'ikirere (0.24±0.06) m wa sodium chloride aerosol bwari butari munsi ya 95% mu gihe cy'umuvuduko w'umwuka (85±2)L/min, ni ukuvuga ko buhuye na N95 (cyangwa FFP2) n'ibirenze ibyo.

2. Ubudahangarwa bwo gukurura: Ubudahangarwa bwo gukurura ntibugomba kurenza 343.2Pa hakurikijwe ibipimo byavuzwe haruguru.

(2) Udupfukamunwa two kubaga

Dukurikije ibisabwa mu rwego rwa tekiniki bya YY 0469-2004 ku birebana n'udupfukamunwa two kubaga, ibipimo by'ingenzi bya tekiniki birimo ubushobozi bwo kuyungurura, ubushobozi bwo kuyungurura bagiteri no kudahumeka:

1. Uburyo bwo kuyungurura: Uburyo bwo kuyungurura bw'umurambararo w'ikirere (0.24±0.06) m wa sodium chloride aerosol bwari butari munsi ya 30% mu gihe cy'umuvuduko w'umwuka (30±2)L/min);

2. Uburyo bwo kuyungurura bagiteri: Mu bihe byagenwe, ubushobozi bwo kuyungurura bwa staphylococcus aureus aerosol ifite umurambararo mpuzandengo wa (3±0.3) m bwari butari munsi ya 95%;

3. Ubudahangarwa bwo guhumeka: Mu gihe cyo kuyungurura neza, ubushobozi bwo guhumeka ntibugomba kurenza 49Pa kandi ubushobozi bwo guhumeka ntibugomba kurenza 29.4Pa.

(3) Udupfukamunwa dusanzwe two kwa muganga

Dukurikije amahame ngenderwaho y’ibicuruzwa byanditswe (YZB), ibisabwa ku buryo bwo kuyungurura uduce duto na bagiteri muri rusange ntibihagije, cyangwa ibisabwa ku buryo bwo kuyungurura uduce duto na bagiteri biri hasi ugereranyije n’iby’udupfukamunwa two kubaga kwa muganga n’udupfukamunwa two kurinda.

(4) Udupfukamunwa dusanzwe dukoreshwa mu gihe cyo gukoresha udupfukamunwa

Udupfukamunwa dusanzwe tw'ijipo ntabwo ducungwa nk'ibikoresho by'ubuvuzi
