Inoveli coronavirus pneumonia izise abantu ekuqondeni okunzulu ngomonakalo omkhulu wezifo ezosulelayo eluntwini ukusukela ngeyoMnga kunyaka ophelileyo. Isitshixo kuthintelo losulelo olunzulu kunye nocwangciso lolawulo kukwenza kakuhle kuthintelo lobhubhane kunye nolawulo nokucoca indawo yokhathalelo lwesigulana.
Kuphando lwelabhoratri, itekhnoloji yokukhanya okuphezulu okuphezulu kuye kwangqinwa ukuba kuyasebenza ukubulala iintsholongwane kunye nokubulala iintsholongwane. Ukuqhubela phambili ngokufunda ngokusebenza kwendalo esingqongileyo kunye nokusebenziseka kwale teknoloji ingadibaniyo, iZiko loPhando lobuchwephesha liqhube isifundo seenyanga ezine kwisibhedlele iQueen's North London, e-UK.

Olu phononongo lwenziwa ukusuka ngoJulayi ka-2014 ukuya ku-Novemba ngo-2014. Kwenziwe iiwadi ezingama-40 zokubekwa esibhedlele njengeesampulu zophononongo. Emva kokuba abaguli bekhululwe esibhedlele, bacocwa ngesandla ngesisombululo sehypochlorite, kwaye ekugqibeleni babulawa ngamayeza okubulala iintsholongwane. Emva koko, iingcali zithathe iisampulu zebacteria ye-aerobic, zaveza ipleyiti ye-agar egonyelweyo kwindawo engakhathalelwanga sisigulana, kwaye yavavanya ukubetha kwe-ultraviolet ukubulala iintsholongwane Iziphumo zezixhobo kwintsholongwane ziya kubhala neemvakalelo zabasebenzi besibhedlele ngokusetyenziswa kwesixhobo.

Indlela yovavanyo

Iqela lophando lenze uphononongo lokuthelekisa isampulu yeendawo zokunxibelelana ezihamba ngesantya esiphezulu ezintlanu (ukhuko lwebhedi, iitafile zepallet, izibambo zokubamba kwigumbi lokuhlambela, izihlalo zangasese kunye nezibambo zompompo kwigumbi lokuhlambela) ngaphambi kokubulala iintsholongwane, emva kokubulala iintsholongwane kunye nasemva kokubulala iintsholongwane kwezixhobo zokubulala iintsholongwane ze-ultraviolet ukuvavanya ukusebenza kwazo yezixhobo ze-ultraviolet ezibulala iintsholongwane ekunciphiseni ungcoliseko lokusingqongileyo kwiiwadi ezizimeleyo zezigulana ezikhutshiweyo ngesondo.

Ukukhethwa kwesampulu

Khetha iwadi (amagumbi ayi-6 ngeyunithi) kwiiyunithi zovavanyo lwezonyango ezibi. Ilabhoratri igqitywa kwiziko ledatha yothintelo losulelo kunye nolawulo lokusetyenziswa kwabathinteli bosulelo kunye nabasebenzi bolawulo Iindlela zokukhetha elebhu yile ilandelayo:

(1) Kufuneka ibe ligumbi elinye;

(2) Kufuneka uhlale iiyure ezingama-48 ubuncinci;

(3) Kufuneka ususwe kwangolo suku lokuqokelelwa kwesampulu;

(4) Kufuneka isetyenziswe njengegumbi lokubekwa lodwa.

Inkqubo yovavanyo

Isiseko seesampuli ze-microbiological zaqokelelwa emva kokuphuma, kodwa ngaphambi kokucoca okuqhelekileyo. Iindawo ezihlanu zokunxibelelana rhoqo zavavanywa kuqala yi-trypsin yesoya agar ipleyiti yokunxibelelana (iOxford, iBasingstoke, UK) enobubanzi be-5 mm;

Ukucoca isibhedlele kusetyenziswa i-1000 ppm (0.1%) ye-chlorine ye-disinfectant (activalum

Ngaphezulu; I-Ecolab, i-Cheshire, e-UK) yokucocwa kwetheminali esemgangathweni kunye nesampulu yesibini;

Igumbi lalikhanyiswe yimoto yokubulala iintsholongwane. Amanqaku amathathu akhethwe kwiwadi nganye: macala amabini ebhedi nakwigumbi lokuhlambela. Inqaku ngalinye lalikhanyiselwe i-5min. Emva kokubulala iintsholongwane, iisampulu zaqokelelwa kwiindawo ezifanayo ezi-5 ukugqiba isampulu yokugqibela.

Isampulu eqokelelweyo ibekwe kwindawo ekhethiweyo ngaphambili ukuthintela nakuphi na ukuphambuka okanye utshintsho kwindlela yokucoca. Emva kokuqokelelwa kwesampulu, i-trypsin yesoya ye-agar ipleyiti yokunxibelelana ibuyile elebhu, ikhuliswe emoyeni kwi-37 ° C iiyure ezingama-48, kubalwa kwaye kwarekhodwa inani leeyunithi zekholoni (i-CFU).

Uhlalutyo lwedatha

Igumbi elinye saliwe kuba kwakungekho lwazi malunga nosulelo lwezixhobo zokubetha, kwaye isampulu yehliswa yaya kumagumbi angama-39.

Kwisiseko, elona nani likhulu (93%) lamagumbi angcolisekileyo laqwalaselwa ngaphezulu komgaqo wobhedu, owancitshiswa waba yi-36% emva kokucoca ngesandla kunye ne-7% emva kokubulawa kweentsholongwane yirobhothi ye-ultraviolet ye-disinfection.

Iziphumo zovavanyo

Emva kokuba irobhothi ifakelwe inzalo yi-UV esuswe yintsholongwane, ungcoliseko lwebacteria kwiCFU lwehle ngama-78.4%, ngama-91% asezantsi kunenqanaba lokuqala le-bioburden. I-CFU yee-MDROs kwipleyiti yesikhonkwane yacuthwa nge-5 log. Ngophando nophando, abaqhubi bezixhobo banelisekile kukonwaba kwemveliso.

isiphelo

Ngakumbi ngakumbi nangakumbi izixhobo zokungasebenzi kwe-disinfection zisetyenziswa kwicandelo lonke lonyango ukuqinisekisa ukucoceka kwemeko yesibhedlele. Ngolu vavanyo, safumanisa ukuba:
1. Indibaniselwano yokucoca okwenziweyo kunye nokubulala iintsholongwane kweekhemikhali kusilele ekususeni ngokufanelekileyo ungcoliseko lweentsholongwane kwindalo esingqongileyo.
2. Emva kokusebenzisa ukubetha kwe-ultraviolet izixhobo zokubulala iintsholongwane, ungcoliseko lomphezulu wewadi yokuzihlukanisa luye lwancitshiswa kakhulu.
