Tekinoroji yekuchenesa mweya muwadhi yekuparadzanisa vanhu vane kumanikidzwa kusina kunaka

01. Chinangwa chewadhi yekuparadzanisa kumanikidzwa kusina kunaka

Wadhi yekuparadzanisa vanhu vane pressure isina kunaka ndeimwe yenzvimbo dzezvirwere zvinotapukira muchipatara, kusanganisira mawadhi ekuparadzanisa vanhu vane pressure isina kunaka pamwe nemakamuri ekubatsira. Mawadhi ekuparadzanisa vanhu vane pressure isina kunaka ndiwo mawadhi anoshandiswa muchipatara kurapa varwere vane zvirwere zvinofamba nemhepo zvakananga kana zvisina kunanga kana kuferefeta varwere vanofungidzirwa kuti vane zvirwere zvinofamba nemhepo. Wadhi inofanira kuchengetedza pressure isina kunaka kune nharaunda iri pedyo kana mukamuri rakabatana nayo.

02. Kuumbwa kwewadhi yekuparadzanisa kumanikidzwa kwakaipa

Wadhi yekuparadzanisa mweya ine simba ine sisitimu yekupa mweya, sisitimu yekuburitsa mweya, imba yekuchengetera mweya, bhokisi repasi uye chivakwa chekuchengetedza. Zvinochengetedza pamwe chete simba rekupa mweya rine simba risingapindike kana tichienzanisa nenyika yekunze uye zvinova nechokwadi chekuti zvirwere zvinotapukira hazvipararire nemhepo. Kuumbwa kwesimba risingapindike: simba remhepo > (simba rekupa mweya + simba rekupa mweya unobuda); seti yega yega yeICU ine simba rine sisitimu yekuburitsa mweya, kazhinji ine mhepo itsva uye masisitimu akazara ekuburitsa mweya, uye simba risingapindike rinoumbwa nekugadzirisa simba remhepo uye simba rekupa mweya. Simba, simba rekupa mweya uye simba rekupa mweya zvinocheneswa kuti zvive nechokwadi chekuti kufamba kwemhepo hakuparadzi kusvibiswa.

03. Modhi yefirita yemhepo yekudzivirira kumanikidzwa kusina simba

Mhepo inobuda nemhepo inoshandiswa muchikamu chekuparadzanisa pressure negative zvinoseferwa nemafirita emhepo. Tora chikamu chekuparadzanisa cheVulcan Mountain semuenzaniso: chiyero chekuchenesa chechikamu ikirasi 100000, chikamu chekuparadzanisa mweya chine mudziyo wekusefa weG4+F8, uye nzvimbo yekusefa yemhepo yemukati inoshandisa H13 hepa air supply yakavakirwa mukati. Chikamu chekuburitsa mweya chine mudziyo wekusefa weG4+F8+H13. Zvipembenene zvinotapukira hazviwanzovapo zvega (ingave SARS kana coronavirus itsva). Kunyangwe zviripo, nguva yazvo yekurarama ipfupi kwazvo, uye mazhinji acho akabatanidzwa kumaaerosols ane dhayamita yezvikamu zviri pakati pe0.3-1μm. Modhi yekusefa yemhepo ine matanho matatu imusanganiswa unoshanda wekubvisa zvipembenene zvinotapukira: firita yekutanga yeG4 ine basa rekubvisa zvipembenene padanho rekutanga, kunyanya kusefa zvidimbu zvikuru pamusoro pe5μm, nekushanda kwekusefa >90%; firita yeF8 medium bag ine basa redanho rechipiri rekusefa, kunyanya kunanga zvidimbu zviri pamusoro pe1μm, nekushanda kwekusefa >90%; Sefa yeH13 hepa ifirita inosefa mativi ari pamusoro pe0.3 μm, ine simba rekusefa >99.97%. Sefirita inosefa mativi, inosarudza kuchena kwemhepo inobuda uye kuchena kwenzvimbo yakachena.

Zvishandiso zveH13 hepa filter:

• Kusarudzwa kwezvinhu zvakanaka kwazvo, kushanda zvakanaka, kusapindirana kwakaderera, kusapindirana nemvura uye kusapindirana kwebhakitiriya;

• Pepa re origami rakatwasuka uye daro rekupeta rakafanana;

• Mafirita eHepa anoedzwa rimwe nerimwe risati rabuda mufekitori, uye avo chete vanopasa bvunzo ndivo vanobvumirwa kubuda mufekitori;

• Kugadzira nharaunda yakachena kuderedza kusvibiswa kunobva kwadzo.

04. Mimwe michina yekuchenesa mweya mumawadhi ekudzivirira kumanikidzwa kwakaipa

Imba yekuchengetera inofanira kuiswa pakati penzvimbo yakajairika yekushandira nenzvimbo yekudzivirira neyokudzora iri muwadhi yekuparadzanisa kumanikidzwa kusina simba, uye pakati penzvimbo yekudzivirira neyokudzora nenzvimbo yekudzivirira neyokudzora, uye musiyano wekumanikidzwa unofanira kuchengetedzwa kudzivirira kutenderera kwemhepo zvakananga uye kusvibiswa kwedzimwe nzvimbo. Seimba yekuchinja, imba yekuchengetera inofanirawo kupihwa mweya wakachena, uye mafirita ehepa anofanira kushandiswa kupa mweya.

Zvinhu zviri mubhokisi rehepa:

• Zvinhu zviri mubhokisi zvinosanganisira ndiro yesimbi yakapfapfaidzwa uye ndiro yesimbi isina ngura yeS304;

• Mapazi ese ebhokisi akasungirirwa zvizere kuitira kuti bhokisi rigare rakavharika kwenguva refu;

• Kune mhando dzakasiyana dzekuvhara dzinoshandiswa nevatengi, dzakadai sekuvhara kwakaoma, kuvhara kwakanyorova, kuvhara kaviri kwakaoma uye kwakanyorova uye kudzvanywa kwakashata.

Panofanira kunge paine bhokisi rekutumira zvinhu pamadziro emakamuri ekuchengetera zvinhu nemakamuri ekuchengetera zvinhu. Bhokisi rekutumira zvinhu rinofanira kunge riri hwindo rekutumira zvinhu rine magonhi maviri rinokiyiwa nemasuo maviri. Chinhu chikuru ndechekuti magonhi maviri aya akakiyiwa. Kana gonhi rimwe rikavhurwa, rimwe gonhi harigone kuvhurwa panguva imwe chete kuitira kuti pasave nemhepo yakananga mukati nekunze kwekamuri rekuchengetera zvinhu.
