Novel coronavirus pneumonia yakaunzira vanhu nzwisiso yakakomba yekukuvara kukuru kwezvirwere zvinotapukira munharaunda yevanhu kubva muna Zvita wegore rapfuura. Chinokosha chekudzivirira hutachiona hwakakwana uye kuronga kuronga kuita zvakanaka mukudzivirira kwedenda uye kutonga uye kuchenesa nzvimbo yekutarisira varwere.
Mukutsvagurudza kwerabhoritari, pulsed yakakwira-yakasimba mwenje tekinoroji yakaratidzirwa kuve inoshanda mukuuraya utachiona uye kutapudza. Kuti uenderere mberi nekudzidza kugona kwezvakatipoteredza uye kugona kweiyi isiri-yekudyara tekinoroji, nyanzvi Yekutsvagisa Institute yakaita chidzidzo chemwedzi mina paQueen's Hospital kuNorth London, UK.

Chidzidzo ichi chakaitwa kubva muna Chikunguru 2014 kusvika Mbudzi 2014. Makamuri makumi mana ekuzviparadzanisa muchipatara akasarudzwa semuenzaniso wekudzidza. Mushure mekunge varwere vaburitswa muchipatara, ivo vakacheneswa nemaoko neiyo hypochlorite solution, uye pakupedzisira vakaomeswa nepulse ultraviolet disinfection michina. Mushure meizvozvo, nyanzvi dzakatora masampula ebacteria eerobic, akafumura iyo inoculated agar ndiro kunzvimbo isina kuchengetwa nevarwere, uye yakaedzwa pulse ultraviolet disinfection Mhedzisiro yemidziyo pane microorganism ichatorawo manzwiro evashandi vepachipatara nezvekushandisa kwemidziyo.

Nzira yekuedza

Dare rekutsvagisa rakagadzira chidzidzo chekuenzanisa sampuro shanu dzakakwira-frequency nzvimbo dzekubata (mabhedha emabhedha, matafura emubhedha, zvigaro zvekugezera, zvigaro zvechimbuzi nemabhegi epombi yekugezera) isati yauraya utachiona, mushure mekuuraya disinfection uye mushure mekuuraya disinfection yemidziyo yeplused ultraviolet disinfection kuongorora kushanda. ye pulsed ultraviolet disinfection michina mukudzora kusvibiswa kwezvakatipoteredza mumawadhi ari ega evarwere vakasununguka Bonde.

Sample kusarudzwa

Sarudza mawadhi (makamuri matanhatu pachikamu chimwe) kubva kumatunhu ekuongorora ekurapa. Rabhoritari inoonekwa ne database yekudzivirira hutachiona uye kudzora kwekushandisa kwehutachiona kudzivirira uye kudzora vashandi. Maitiro ekusarudzwa erabhoritari ndeaya anotevera:

(1) Inofanirwa kuve imba imwechete;

(2) Inofanira kugara angangoita maawa makumi mana nemasere;

(3) Inofanirwa kubviswa pazuva rimwe chetero rekuunganidzwa kwemuenzaniso;

(4) Inofanirwa kushandiswa sekamuri yekudyidzana yekuzviparadzanisa.

Maitiro ekuyedza

Baseline microbiological sampuli dzakaunganidzwa mushure mekudonhedza, asi zvisati zvaitika nguva dzose kuchenesa. Mashanu mashanu akakwirira maficha ekutaurirana akatanga kutorwa sampu ne trypsin soya agar yekubata ndiro (Oxford, Basingstoke, UK) ine dhayamita ye5 mm;

Vanochenesa zvipatara vanoshandisa 1000 ppm (0.1%) chlorine disinfectant (activalum

Uyezve; Ecolab, Cheshire, UK) yeyakajairika terminal yekuchenesa uye yechipiri sampling;

Imba yacho yakanga yakaburitswa nemhepo inouraya utachiona robhoti. Mapoinzi matatu akasarudzwa kuwadhi yega yega: mativi maviri emubhedha uye yekugezera. Pfungwa imwe neimwe yaiburitsirwa 5min. Mushure mekuisa utachiona, masampuli akaunganidzwa kubva kunzvimbo imwechete shanu kupedzisa sampling yekupedzisira.

Iyo sampuli yakaunganidzwa inoiswa pane yakasarudzika nzvimbo yekudzivirira chero kutsauka kana shanduko yenzira yekuchenesa. Mushure mekuunganidzwa kwemuenzaniso, trypsin soya agar yekubata ndiro yakadzokera murabhoritari, yakasimudzwa mumhepo pa37 ° C kwemaawa makumi mana nemasere, yakaverengerwa uye yakarekodha huwandu hwenzvimbo dzekuumba zvikamu (CFU).

Kuongorora dhata

Imwe imba yakarambwa nekuti pakanga pasina ruzivo nezve hutachiona hwemidziyo yekupomba, uye muyenzaniso wakadzikiswa kusvika pamakamuri makumi matatu nemapfumbamwe.

Pakutanga, chikamu chikuru (93%) chemakamuri akasvibiswa chakaonekwa pamusoro penzvimbo dzemubhedha, idzo dzakadzikiswa kusvika pa36% mushure mekuchenesa nemaoko uye 7% mushure mekutapukirwa nehutachiona neiyo pulsed ultraviolet disinfection robhoti.

mhedzisiro yekuyedza

Mushure mekunge robhoti yaiswa sterilized ne pulsed UV, kusvibiswa kwebhakitiriya muCFU kwakadzikira ne78.4%, 91% kuderera pane yekutanga bioburden level. Iyo CFU yeMDROs pane iyo chipikiri ndiro yakaderedzwa ne5 danda. Kuburikidza nekuferefeta uye nekutsvaga, vashandisi vezvigadzirwa vanogutsikana nekunyaradza kwechigadzirwa.

mhedziso

Zvakawanda uye zvitsva zvigadzirwa zvisiri zvekubata disinfection michina inoshandiswa mune yese yekurapa kuchengetedza kuchena kwenzvimbo yechipatara. Kuburikidza nekuyedza uku, takaona kuti:
1. Iko kusanganiswa kwekuchenesa kwekugadzira uye kemikari disinfection yakundikana kubvisa zvinobudirira kusvibiswa kwehutachiona mumhoteredzo.
2. Mushure mekushandisa pulse ultraviolet disinfection michina, iko kusvibiswa kwepasi kwekuzviparadzanisa wadhi kwakadzikira zvakanyanya.
