A blood pressure cuff (100) comprises a flexible outer ring portion (120), an inner hole (122) is opened on the outer ring portion (120), and is a straight blind hole. The outer ring portion (120) is clamped, in an interference-fit manner, on the outer wall of an air plug (200) of the blood pressure cuff through the inner hole (122). The outer ring portion (120) increases in thickness from one end close to the opening of the inner hole (122) to the other end. The outer ring portion (120) elastically deforms due to the lateral extrusion by the air plug (200), and is provided on the outer wall of the air plug (200). The outer ring portion (120) is thinner at the opening of the inner hole (122), and easily deforms accordingly, so that the air plug (200) easily inserts into the inner hole (122) and moreover, the outer ring portion (120) is thicker at the hole bottom of the inner hole (122), so that the blood pressure cuff (100) is securely disposed on the air plug (200) and cannot easily slip down from the air plug (200). The blood pressure cuff (100) is embedded into the inner wall of the air plug(200) and/or tightly clamped on the outer wall of the air plug (200), so that the air plug (200) is sealed at the opening, thereby preventing fine particles such as dust and disinfectant from entering the inside of the blood pressure cuff, preventing air path jam and corrosion and rust of air path components, and further prolonging the service life of the blood pressure measurement device.Un brassard de tensiomètre (100), comprend une partie bague extérieure souple (120), un trou intérieur (122) est ouvert sur la partie bague extérieure (120) et est un trou borgne droit. La partie bague extérieure (120) est serrée, par ajustement avec serrage, sur la paroi extérieure dun raccord dair (200) du brassard de tensiomètre à travers le trou intérieur (122). La partie bague extérieure (120) augmente en épaisseur dune première extrémité proche de louverture du trou intérieur (122) à la
