I-nitrogen yolwelo (LN2) idlala indima ebalulekileyo kwihlabathi loncedo lobuchwephesha bokuzala, njengesixhobo sokuya kwi-cryogenic sokugcina imathiriyeli exabisekileyo yebhayoloji, efana namaqanda, amadlozi, kunye neembumba.Ibonelela ngamaqondo obushushu aphantsi kakhulu kunye nokukwazi ukugcina imfezeko yeselula, i-LN2 iqinisekisa ukugcinwa kwexesha elide kwezi sampuli zibuthathaka.Nangona kunjalo, ukuphatha i-LN2 kubangela imiceli mngeni ekhethekileyo, ngenxa yobushushu bayo obubanda kakhulu, isantya sokwanda ngokukhawuleza kunye neengozi ezinokubakho ezinxulumene nokufuduswa kweoksijini.Sijoyine njengoko siphengulula kumanyathelo okhuseleko ayimfuneko kunye nezona nkqubo zifanelekileyo eziyimfuneko ukugcina indawo ekhuselekileyo nesebenzayo yogcino lwecryo, abasebenzi abakhuselayo, kunye nekamva lonyango lokuchuma.

Ukunciphisa imingcipheko ekusebenzeni kweGumbi leCryogenic
Kukho imingcipheko eyahlukeneyo eyayanyaniswa nokuphathwa kwe-LN2, kubandakanywa ukuqhuma, ukuphefumla, kunye nokutshisa kwe-cryogenic.Ekubeni umlinganiselo wokwandiswa komthamo we-LN2 malunga ne-1: 700 - oku kuthetha ukuba i-1 ilitha ye-LN2 iya kunyuka ukuvelisa malunga ne-700 yeelitha zegesi ye-nitrogen - ukunyamekela okukhulu kufuneka kuthathwe xa uphatha iiglasi zeglasi;iqamza lenitrogen linokuyiqhekeza iglasi, lidale iintlanti ezikwaziyo ukwenza ukwenzakala.Ukongeza, i-LN2 inobunzima bomphunga obumalunga ne-0.97, okuthetha ukuba ixinene kancinci kunomoya kwaye iya kudibana kumgangatho ophantsi xa ubushushu buphantsi kakhulu.Oku kuqokelelana kubangela ingozi yokuphefumla kwiindawo ezivaliweyo, ukuphelisa inqanaba le-oksijini emoyeni.Iingozi zokuphefumla zongezwa ngakumbi kukukhululwa ngokukhawuleza kwe-LN2 ukwenza umphunga wamafu enkungu.Ukuba sesichengeni kulo mphunga ubanda kakhulu, ngakumbi eluswini okanye emehlweni - nokuba ngokufutshane - kunokukhokelela ekutshisweni yingqele, yiqabaka, ukonakala kwezicubu okanye umonakalo osisigxina wamehlo.
Ezona Nkqubo zilungileyo
Yonke iklinikhi yokuchuma kufuneka yenze uvavanyo lwangaphakathi lomngcipheko malunga nokusebenza kwegumbi layo le-cryogenic.Ingcebiso ngendlela yokwenziwa kolu vavanyo inokufumaneka kwiiKhowudi zokuSebenza (CP) ezipapashwa kwiBritish Compressed Gases Association.1 Ngokukodwa, i-CP36 iluncedo ukucebisa malunga nokugcinwa kweegesi ze-cryogenic kwi-site, kwaye i-CP45 inika isikhokelo kwi uyilo lwegumbi lokugcina i-cryogenic.[2,3]
NO.1 Uyilo
Indawo efanelekileyo yegumbi le-cryogenic yeyona ibonelela ngokufikeleleka okukhulu.Ukuqwalaselwa ngononophelo kokubekwa kwesikhongozeli sokugcina i-LN2 kuyafuneka, njengoko kuya kufuna ukuzaliswa ngenqanawa enoxinzelelo.Ngokufanelekileyo, isitya sonikezelo lwenitrogen elulwelo kufuneka sibekwe ngaphandle kwegumbi lokugcina isampulu, kwindawo engena umoya kwaye ikhuselekile.Ukufumana izisombululo ezinkulu zokugcina, isitya sokubonelela sihlala sidibaniswa ngokuthe ngqo kwisitya sokugcina nge-hose yokudlulisa i-cryogenic.Ukuba ukucwangciswa kwesakhiwo akuvumeli ukuba inqanawa yokubonelela ibekwe ngaphandle, kufuneka kuthathelwe ingqalelo eyongezelelweyo ngexesha lokuphatha i-nitrogen engamanzi, kunye novavanyo olucacileyo lwengozi kufuneka lwenziwe, olubandakanya ukujongwa kunye neenkqubo zokukhutshwa.
NO.2 Ukungenisa umoya
Onke amagumbi e-cryogenic kufuneka ahlanjululwe kakuhle, kunye neenkqubo zokukhupha i-nitrogen gas build-up kunye nokukhusela kwi-oxygen depletion, ukunciphisa umngcipheko wokuphefumula.Inkqubo enjalo kufuneka ifanelekele igesi ebandayo ye-cryogenically, kwaye idibaniswe nenkqubo yokubeka iliso ye-oksijini yokutshatyalaliswa kwe-oksijini ukuze ibone xa izinga le-oksijini lehla ngaphantsi kweepesenti ze-19.5, apho kuya kuqalisa ukunyuka kwezinga lokutshintsha komoya.Imibhobho yokutsala kufuneka ibekwe kumgangatho ophantsi ngelixa izinzwa zokuncipha kufuneka zibekwe malunga nemitha e-1 ngaphezu komgangatho womgangatho.Nangona kunjalo, indawo echanekileyo kufuneka kugqitywe ngayo emva kovavanyo lwesayithi oluneenkcukacha, njengoko izinto ezinje ngobungakanani begumbi kunye noyilo luya kuchaphazela ukubekwa okuphezulu.I-alam yangaphandle kufuneka ifakwe ngaphandle kwegumbi, ibonelele zombini izilumkiso ezivakalayo nezibonakalayo ukubonisa xa kungakhuselekanga ukungena.
NO.3 Ukhuseleko lomntu
Ezinye iikliniki zisenokukhetha ukuxhobisa abasebenzi ngeemonitha zeoksijini zobuqu kwaye baqeshe inkqubo yobungane apho abantu baya kuthi bangene kwigumbi lokukhala ngababini, kuncitshiswe ixesha apho umntu omnye eba segumbini nangaliphi na ixesha.Luxanduva lwenkampani ukuqeqesha abasebenzi kwinkqubo yokugcina ebandayo kunye nezixhobo zayo kwaye abaninzi bakhetha ukuba abasebenzi benze izifundo zokhuseleko nitrogen online.Abasebenzi kufuneka banxibe izixhobo ezifanelekileyo zokhuseleko lobuqu (PPE) ukukhusela ekutshiseni okukhalayo, kuqukwa nokhuseleko lwamehlo, iiglavu/iigaunti, izihlangu ezifanelekileyo, kunye nedyasi yelebhu.Kubalulekile ukuba bonke abasebenzi bafumane uqeqesho loncedo lokuqala malunga nendlela yokujongana nokutsha kwe-cryogenic, kwaye kufanelekile ukuba kubekho unikezelo lwamanzi adikidiki kufutshane ukuze kuhlanjwe ulusu ukuba kuthe kwakho umtshi.
NO.4 Ugcino
Isikhephe esicinezelekileyo kunye nesikhongozeli se-LN2 asinazo iindawo ezihambayo, nto leyo ethetha ukuba ishedyuli yokulondolozwa kwesiseko yonyaka yiyo yonke into efunekayo.Ngaphakathi koku, imeko ye-hose ye-cryogenic kufuneka ihlolwe, kunye naluphi na ukutshintshwa okufunekayo kwee-valve zokukhulula ukhuseleko.Abasebenzi kufuneka baqhubeke bejonga ukuba akukho ndawo zokukhenkceza – nokuba kukwisikhongozelo okanye kwisikhephe se-feeder – nto leyo enokubonisa ingxaki ngevacuum.Ngokuqwalaselwa ngenyameko kuyo yonke le miba, kunye neshedyuli yokugcinwa rhoqo, imikhumbi enoxinzelelo lwengqondo ingahlala ukuya kutsho kwiminyaka engama-20.
Ukuqukumbela
Ukuqinisekisa ukhuseleko lwegumbi logcino lweklinikhi yekliniki yokuchuma apho kusetyenziswa i-LN2 kubaluleke kakhulu.Ngelixa le bhlog ichaze imiba yokhuseleko eyahlukeneyo, kubalulekile ukuba ikliniki nganye yenze uhlolo lwayo lwangaphakathi lomngcipheko ukujongana neemfuno ezithile kunye neengozi ezinokubakho.Ukusebenzisana nababoneleli beengcali kwizikhongozeli zokugcina ezibandayo, ezifana ne-Haier Biomedical, kubalulekile ukuhlangabezana neemfuno ze-cryostorage ngokufanelekileyo nangokukhuselekileyo.Ngokubeka phambili ukhuseleko, ukuthobela ezona zenzo zilungileyo, nokusebenzisana neengcali ezithembekileyo, iikliniki zokuchuma zinokugcina imeko ekhuselekileyo yogcino lwecryo, zikhusela abasebenzi kunye nokusebenza kwezinto ezixabisekileyo zokuzala.
