Title
(EN) MEDICO-SURGICAL TUBE
(FR) TUBE MEDICO-CHIRURGICAL
Abstract
(EN) A laryngeal mask airway has a main tubular shaft (1) with a channel (2) of part circular section opening along its external surface. A mask portion (5) is attached to the patient end of the shaft, including a mount (50) and a cuff (60) attached to the mount. A channel (55) extends along the mount (50) from the channel (2) in the shaft (1) to the cuff (60). A small-diameter tube (70) opens at one end into the cuff (60) and extends along the channels (55 and 2) in the mount (50) and in the shaft (1). The channel (2) in the shaft (1) mechanically retains the small-diameter tube (70), the tube extending out of the channel through one of several notches (20) spaced along the channel. The tube (70) can be peeled away from the shaft (1) to extend out of one of the other notches (20), so that the shaft can be cut shorter.
(FR) La présente invention concerne un dispositif respiratoire à masque laryngé présentant une tige tubulaire principale (1) pourvue d'un canal (2) de partie circulaire s'ouvrant le long de sa surface externe. Une partie masque (5) fixée à l'extrémité de la tige du patient comprend une ouverture (50) et un ballonnet (60) fixé à cette ouverture. Un canal (55) traverse l'ouverture (50) du canal (2) jusqu'au ballonnet (60), en passant par la tige (1). Un tube de petit diamètre (70) s'ouvre par une extrémité dans le ballonnet (60) et s'étend le long des canaux (55, 2) pour arriver dans l'ouverture (50) et la tige (1). Le canal (2) de la tige (1) retient mécaniquement le tube de petit diamètre (70), le tube s'étendant à l'extérieur du canal par une ou plusieurs encoches (20) espacées le long du canal. Ce tube (70) peut se séparer de la tige (1) pour sortir de l'une des encoches (20), de façon à raccourcir la tige.
