Umnyango wezempi waseMelika owenziwa ngezokwelapha ukuthuthukiswa kwezimali (usammamda) uhlanganise nomunye wabalingani bayo ekuthuthukiseni idivaysi entsha yezokwelapha, engaba nomthelela omkhulu ekwelapheni izilimele ezimweni zokulwa. Idalwe ngucwaningo lwe-TDA futhi ixhaswe njengengxenye yohlelo lokucwaninga olusha lwenkonzo yezokuvikela, i-lactated ringer generator iyithuluzi elilula elingathembisa isisombululo se-ringer's lactate (LR-solution) ezimweni ezinzima ezitholakala emanzi atholakalayo endawo atholakalayo Imithombo. Idivayisi isebenzisa ubuchwepheshe obunelungelo lobunikazi ukukhiqizwa kwamaphakeji wokufakwa kwe-intravenous kosayizi we-lindo eyodwa kusuka kusisombululo sikasawoti esihlanganisiwe se-lactate ye-ringer.
Okubandakanya i-sodium chloride, i-sodium lactate, i-potassium chloride ne-calcium chloride LR-solution kusetshenziswa ngokuyinhloko ekwelashweni kokuphelelwa ngamandla, okokufaka kwezidakamizwa nokubuyisela ibhalansi ye-liquid ngemuva komonakalo womzimba. Kusetshenziselwa futhi ukwelapha okulinganiselayo kwe-hemorrhagic, njengoba kukhonjisiwe ukuthi kwandisa ukusinda kokuqala ezigulini futhi kunciphise amathuba okulimaza izitho.
Ngokusho kweMenenja ye-USAmmda Project Division, i-Austin Langdon,
Le divayisi encane izokwehlisa kakhulu impahla ebonakalayo neyobuchwepheshe yamasosha ahambisana nokuhamba kanye nokugcinwa kwesisombululo se-lactate lactate, esetshenziswa njengokushintshwa kwegazi. Idivayisi entsha ingakhiqiza isixazululo se-LR kusuka cishe kunoma yimuphi umthombo wamanzi, kufaka phakathi amanzi emgodini. Ibutho le-LR Solution Generator ibutho lizokwandisa amathuba ethu okutakula, ukusiza ukunciphisa izidingo zamaketanga okunikezela kwamalungiselelo.
Idivayisi inesisindo esingaphansi kwama-5 kg futhi igcinwe kubhede eliqinile lobubanzi obungama-25 cm nge-15 cm kanye nenani elingamasentimitha ayi-15. Uhlelo lokuhlanza lusebenza ebhethri le-lithium-ion elingakhiqiza ngaphezu kwama-30 LR Shaja.
* Isixazululo se-Ringer Lactate (eyaziwa nangokuthi isixazululo se-sodium lactate kanye ne-Hartman Solution) - Ingxube ye-sodium chloride, i-sodium lactate, i-potassium chloride ne-calcium chloride emanzini. Isetshenziselwa ukufaka esikhundleni se-ketshezi nama-electrolyte kulabo abanevolumu ephansi yegazi noma umfutho wegazi ophansi.
