Abstract

The hollow shaft (3) of the dilator (1) leads into a tapering section (4) and has a flange (5) at the top end of larger diameter than that of the shaft.. The constant diameter of the shaft corresponds to the diameter of the tracheotomy tube being inserted. The tapering section tilts in relation to the vertical axis of the dilator and contains at least one hole (6).

Dilatateur de vérification pour l' insertion d'un tube de trachéotomie dans la trachée d'un patient Domaine de l' invention L' invention se rapporte à un dilatateur de vérification destiné à l' insertion dun tube de trachéotomie dans la trachée dun patient. Outre son application à la dilatation,  Field of the Invention The invention relates to a verification dilator for the insertion of a tracheostomy tube into the trachea of a patient.

Arrière-plan de l' invention I1 est connu d'insérer un tube de trachéotomie dans un patient en insérant une aiguille creuse dans la trachée, puis en faisant glisser une canule par dessus l'aiguille dans la trachée. L'aiguille est retirée, un fil de guidage est ensuite passé dans la trachée en le faisant passer à travers la canule. La canule est retirée, laissant le fil en place et un dilatateur fixé au fil est introduit dans la trachée. La dilatateur possède des mâchoires incurvées qui s'ouvrent de manière à écarter la trachée. Le dilatateur est ensuite  BACKGROUND OF THE INVENTION It is known to insert a tracheostomy tube into a patient by inserting a hollow needle into the trachea, then dragging a cannula over the needle into the trachea. The needle is withdrawn, a guide wire is then passed through the trachea by passing it through the cannula. The cannula is removed, leaving the wire in place and a dilator attached to the wire is introduced into the trachea. The dilator has curved jaws that open to spread the windpipe. The dilator is then

Le diamètre extérieur de la partie cylindrique 3 est seulement légèrement plus grand que le diamètre du tube de trachéotomie à insérer dans la trachée. Cette taille est inscrite sur la collerette 5. La longueur totale de la partie cylindrique est d' environ 5 cm. Ainsi, la partie cylindrique 3 possède un diamètre extérieur supérieur de 0,50 mm au diamètre extérieur du tube de trachéotomie à insérer. La partie conique 4 du dilatateur comporte un ou plusieurs trous 6 pour introduire de l'oxygène si nécessaire. Un fil de guidage peut être inséré sur toute la longueur du dilatateur de vérification. La partie supérieure permet une meilleure  giant by a curved conical part 4 inclines angularly with respect to the longitudinal axis of the dilator.

The outside diameter of the cylindrical part 3 is only slightly larger than the diameter of the tracheostomy tube to be inserted into the trachea. This size is written on the collar 5. The total length of the cylindrical part is approximately 5 cm. Thus, the cylindrical part 3 has an outside diameter greater than 0.50 mm than the outside diameter of the tracheostomy tube to be inserted. The conical part 4 of the dilator has one or more holes 6 for introducing oxygen if necessary. A guidewire can be inserted over the entire length of the verification dilator. The upper part allows better
