Refers to American thoracic surgeon Henry Heimlich (
亨利·
海姆利克, 1920-2016), who in 1974 publicized the abdominal-thrust technique now bearing his name (
海姆利克急救法 /
海姆利希急救法). The technique dislodges objects blocking the airway in choking victims. The transliteration uses
海 (sea),
姆 (auntie/-m sound),
利 (sharp),
克 (gram/-k) — pure phonetics.
