Ngokwalokhu, ingabe uFrederic Foley wayenelungelo lobunikazi le-catheter kaFoley?
Context:UFoley waqala ukuchaza ukusetshenziswa kwe-catheter ye-balloon yokuzibamba ngo-1929, eyayizosetshenziselwa ukufeza i-hemostasis ngemuva kokuhlinzwa kwe-prostate nge-cystoscopic. Wasebenza ekuthuthukiseni lo mklamo ukuze usetshenziswe njenge-catheter yomchamo, ukuhlinzeka ngokukhishwa okuqhubekayo komchamo, ngawo-1930. Umklamo wakhe wawuhlanganisa ibhaluni eliqhuma ngasekugcineni kweshubhu elalingakhushulwa ngaphakathi kwesinye ukuze ligcine i-catheter ngaphandle kokudonsa noma ukubopha ngaphandle. Lokhu wakubonisa i-American Urologists Society ngo-1935, futhi washicilela iphepha eliwuchaza ngo-1937. Ngesikhathi esathuthukisa i-catheter yakhe, uPaul Raiche we-Davol Rubber Company yaseProvidence, eRhode Island wathola ilungelo lobunikazi ngo-1936. Ezinyangeni ezine kamuva, ngo-October 1936, uFoley wafaka isicelo selungelo lobunikazi, futhi wanikezwa lona ngemva kokuvela phambi kweBhodi Yezikhalazo yehhovisi lamalungelo obunikazi. URaiche wadlulisela lesi sinqumo enkantolo, futhi sahoxiswa, kwabuyiselwa ilungelo lobunikazi kuRaiche. Isicelo sikaFoley sokulalelwa kabusha senqatshwa, ngakho-ke i-patent yahlala noRaiche. https://en.wikipedia.org/wiki/Frederic_Foley
Ngokwalendima, uFrederic Foley wafaka isicelo selungelo lobunikazi kodwa ekugcineni lanikezwa uPaul Riache esikhundleni salokho.
