Egunjini lokuhlola i-B-ultrasound, udokotela wakhama i-ejenti yokuxhumanisa yezokwelapha esiswini sakho, futhi kwazwakala kupholile. Ibukeka icwebile futhi ifana nejeli yakho evamile (yezimonyo). Yebo, ulele embhedeni wokuhlola futhi awuwuboni ngesisu.
Ngemva nje kokuqeda ukuhlolwa kwesisu, ngenkathi uhlikihla "i-Dongdong" esiswini sakho, ukhononda enhliziyweni yakho: "I-smudged, kuyini? Ingabe izongcolisa izingubo zami? Ingabe inobuthi?"
Ukwesaba kwakho kungaphezu kwamandla. Igama lesayensi laleli "mpumalanga" libizwa ngokuthi i-coupling agent (i-ejenti yokuxhumanisa yezokwelapha), futhi izingxenye zayo eziyinhloko yi-acrylic resin (carbomer), i-glycerin, amanzi, nokunye okunjalo. Ayinabuthi futhi ayinambitheki futhi izinzile kakhulu ezindaweni zansuku zonke; ngaphezu kwalokho, ayicasuli isikhumba, ayingcolisi izingubo, futhi isula kalula.
Ngakho-ke, ngemva kokuhlolwa, thatha amaphepha ambalwa udokotela azokunikeza wona, ungawasula ngokuphepha, uwashiye ngokukhululeka, ngaphandle kokuthatha umkhondo wokukhathazeka.
Kodwa-ke, kungani i-B-ultrasound kufanele isebenzise lesi sigqebhezana sezokwelapha?
Ngenxa yokuthi amagagasi e-ultrasonic asetshenziswe ekuhloleni awakwazi ukuqhutshwa emoyeni, futhi ubuso besikhumba sethu abushelelezi, i-ultrasonic probe izoba nezikhala ezincane lapho ihlangana nesikhumba, futhi umoya kuleli gebe uzovimbela ukungena kwamagagasi e-ultrasonic. . Ngakho-ke, kudingeka into ethile (emaphakathi) ukuze kugcwaliswe lezi zikhala ezincane, okuyi-couplant yezokwelapha. Ngaphezu kwalokho, iphinde ithuthukise ukucaca kwesibonisi. Vele, iphinde isebenze "njenge-lubrication", inciphisa ukungqubuzana phakathi kwendawo ye-probe nesikhumba, okuvumela uphenyo ukuthi lushanelwe kalula futhi luphenywe.
Ngaphezu kwe-B-ultrasound yesisu (i-hepatobiliary, amanyikwe, ubende nezinso, njll.), indlala yegilo, isifuba neminye imithambo yegazi iyahlolwa, njll., futhi kusetshenziswa ama-couplants ezokwelapha.
