Title
(EN) OBTURATORS AND TUBE ASSEMBLIES
(FR) OBTURATEURS ET ENSEMBLES TUBES
Abstract
(EN) An obturator (2) for a tracheostomy tube (1) has a shaft (20) with a bullet-shape nose (24) at its patient end and a clip (21) at its machine end with arms (34) engaging recesses (15) on a coupling (13) at the machine end of the tube (1). The clip (21) is rotatably mounted with the shaft (20) by means of an engaging spigot (135) and aperture (213) and is retained angularly by dimples (219) on the clip engaged with recesses (141) on the obturator shaft. The obturator (2) is released from the tube (1) by twisting the clip against the retention of the dimples with the recesses and without applying any twisting force to the patient end of the obturator or tube.
(FR) Selon l'invention, un obturateur (2) pour un tube de trachéotomie (1) comporte un arbre (20) doté d'une pointe en forme de bille (24) à son extrémité patient et d'une attache (21) au niveau de son extrémité machine avec des bras (34) venant en prise avec des évidements (15) sur un accouplement (13) au niveau de l'extrémité machine du tube (1). L'attache (21) est montée rotative avec l'arbre (20) au moyen d'un ergot de mise en prise (135) et d'une ouverture (213) et est retenue angulairement par des alvéoles (219) sur l'attache en prise avec des évidements (141) sur l'arbre d'obturateur. L'obturateur (2) est libéré du tube (1) par torsion de l'attache à l'encontre de la retenue des alvéoles avec les évidements et sans appliquer de force de torsion à l'extrémité patient de l'obturateur ou du tube.
