3 way stopcock

Iingxaki eziqhelekileyo, iindlela zokuphepha kunye neengcebiso xa usebenzisa i-3 way stopcocks

Ukubulala iintsholongwane ngaphambi kokuba uqalise ukuqinisekisa ukuba utyando luyi-aseptic.

Iingxaki eziqhelekileyo ekusebenzeni kunye nendlela yokuziphepha

Kukho iingxaki ezihlala zisenzeka ngexesha lokusebenza, onokuthi udibane nazo ngexesha lokusebenza. Ukuba awuyazi into eyenzekayo, kwaye ungayazi indlela yokujongana nokukhusela, jonga nje oku kulandelayo.

1. Kutheni iyeza lilahlekile?

Impendulo: ①Okokuqala, xa ivalve yendlela-ntathu yonyango ishiya umzi-mveliso, zontathu iitshaneli zivulwa ngokungagqibekanga. Kufuneka sivale isivalo somnye umjelo phambi kokuba siphinde sigcwalise iyeza, njengoko kubonisiwe kuMfanekiso 1. Kuphephe ukuvuza kunye nenkcitho yeyeza elingamanzi ngenxa yengxaki yesithathu yojongano.
②Izizathu ezininzi zokuvuza iyeza zinxulumene nesixhobo sokutofa. Xa usebenzisa i-tee, musa ukususa ipiston yerabha yesirinji. Oku kuya kubangela ukuba ngaphakathi kwesixhobo sokutofa kuvuze, okungayi kuvelisa ibhaktheriya kuphela, kodwa kubangele ukuvuza kweyeza. Iyenzeka.

2. Kutheni eveliswa amaqamza amaninzi nje?

Impendulo: Ukuba umoya okwisirinji kunye nevalve yendlela-ntathu awukhutshwanga, amaqamza amaninzi aya kuveliswa xa iyeza lixutywa, ingakumbi kulwelo olungqindilili. Pusha kwaye utsale iyeza emva naphambili kwisirinji, inani elikhulu lamaqamza liya kuhanjiswa kulwelo, kwaye kunzima ukuthoba. Mhlawumbi ixesha lakho lokuba ndindisholo liphantse ladlula, amaqamza asekho kulwelo, kwaye awunakukwazi kwaphela ukuwusebenzisa. Ke ngoko, kufuneka sikhuphe umoya kwisirinji ngaphambi nangemva kokuba iyeza lolwelo litsalwe, kwaye ngaphambi kokuba iyeza liqale, umoya okwi-tee kufuneka ukhutshiwe, kwaye iyeza litshintshwa kwi-tee.

3. Kutheni inaliti iqhuma ngexesha lenkqubo yokutofa?

Impendulo: Le meko yenzeka ikakhulu kwiisirinji zempumlo ecaba.
①Isirinji yomlomo osicaba ayifani nesirinji yohlobo lwe-screw, ayinamaqhina, ngoko ke itiyi ayinakubotshelelwa kwisirinji.
②Ukuphela kweendlela ezintathu zesirinji yempumlo ecaba kulula ukutyibilika emva kokudibana nolwelo, kwaye ukutyhala ngamandla ngexesha lokusebenza kuya kwandisa ukubonakala kweenaliti ezigqabhukileyo. Ke ngoko, uZemei ucebisa ukuba amanenekazi kunye noodade kufuneka bakhethe isirinji ejikelezayo yokusebenzela ukuxuba amayeza.

4. Kufuneka wenze ntoni xa kukho ulwelo oluninzi?

Impendulo: Isirinji ye-10ml isetyenziswa ngokubanzi kwinaliti yemihla ngemihla, ngoko ke inani elipheleleyo leemveliso ezimbini kwinaliti enye lilawulwa ngokubanzi ngaphakathi kwe-10ml. Kuphephe ukuwa kwepiston emva kokuba i-bolus yomelele kakhulu, ibangela ukuba ibhaktheriya ingene kwaye ivuze iingxaki. Ukuba isixa esisidingayo ukongeza iyeza lidlula i-15ml, kuyacetyiswa ukuba sihlule amaxesha amaninzi kwaye sisebenzise umsebenzi weendlela ezintathu ngokomlinganiselo.

Iingcebiso ezimbini ezisetyenziswa rhoqo ukuzoba iyeza:

1. Zoba iyeza kwibhotile evaliweyo:
Susa indawo esembindini yesivalo se-aluminiyam, emva kokutshatyalaliswa kwentsholongwane yesiqhelo, faka inaliti kwisithinteli sebhotile, kwaye utofe umlinganiselo ofanayo womoya njengeyeza elifunekayo lolwelo kwibhotile ukunyusa uxinzelelo kwibhotile kwaye ugweme uxinzelelo olubi, kwaye emva koko udwebe iyeza lolwelo.

2. Ukutsala iyeza kwi-ampoule:
Beka inaliti ngokuthobileyo phantsi kwenqanaba lolwelo lwe-ampoule, kwaye uzobe iyeza elingamanzi. Musa ukubamba ishafti yepiston ngezandla zakho xa umpompa iyeza, sisiphatho sepiston kuphela.
