Definitions

  • the invention pertains to hand operated articulated intubation stylets.
  • Endotracheal tubes are utilized in a wide variety of medical procedures to provide an unobstructed air passage to a patient's trachea.
  • Intubation is often difficult because of the contours and obstacles encountered in a patient's airway.
  • Perhaps the most difficult step in intubating a patient is maneuvering an endotracheal tube's outboard end into his trachea as opposed to his esophagus.
  • US Patent No. 4,329,983 to Fletcher illustrates and describes a guide device for an endotracheal tube which assists in intubating the trachea.
  • the guide device includes a flexible bar which may be inserted in the endotracheal tube.
  • a flexible line extends along the bar and has a free length at the inner end of the bar. When the line is pulled, the free length shortens and causes the inner end portion of the bar to flex in bowed fashion against the endotracheal tube.
  • US Patent No. 4,529,400 to Scholten illustrates and describes a directable stylet for naso and oroendotracheal intubations including hand operated lever bar and grip support for applying high force to an articulating wire that produces a first curvature and a reverse curvature to facilitate intubation.
  • the present invention is directed towards hand operated articulated intubation stylets including an articulated stylet member with a link at its distal end, a L-shaped lever with a downward depending handle with a free end directed towards the stylet member's distal end for tautening a flexible wire for flexing the link into a flexed positioned to form a hook-like configuration in the stylet member's side view, and a stopper mechanism mounted on the stylet member for stopping the sliding insertion of the stylet member into an endotracheal tube at a suitable position depending on the endotracheal tube's
  • the handle and the link are on opposite sides of the stylet member such that a user conveniently operates the stylet with his fingers stretched out to grip the stylet member and his palm depressing the handle towards the stylet member to flex the stylet member's link into its flexed position for manipulating an endotracheal tube's outboard end for insertion into a patient's trachea.
  • the same stylet can be used with endotracheal tubes with a wide range of Inner Diameters (IDs) from about 5.5mm to about 9mm.
  • IDs Inner Diameters
  • the stylets can be made from metal or plastic components.

  • the endotracheal intubation apparatus 10 also includes a hand operated articulated intubation stylet 20 for sliding insertion into the endotracheal tube 11 for assisting in manipulating the endotracheal tube's outboard end 13 into a patient's trachea as opposed to his esophagus.
  • Figures 2A, 3, 6 and 7 show the stylet 20 has an articulated stylet member 21 with a longitudinal axis 22 with a proximal end 23 and a distal end 24 diverging away from the longitudinal axis 22.

Abstract

Stylet d'intubation articulé à commande manuelle comprenant les éléments suivants: élément de stylet articulé doté d'une biellette à son extrémité distale; levier en L avec poignée orientée vers le bas permettant de tendre un fil flexible servant à fléchir la biellette et à donner une forme de crochet à l'élément de stylet (vu de côté); et mécanisme de butée monté sur l'élément de stylet, destiné à stopper l'insertion dudit élément de stylet dans un tube endotrachéal en un point approprié fonction de la longueur dudit tube. Comme La poignée et la biellette sont disposés sur des extrémités opposées de l'élément de stylet, l'utilisateur peut actionner facilement ce dernier avec la paume de la main et repousser la poignée vers l'élément de stylet, ce qui permet de fléchir la biellette et de manipuler l'extrémité extérieure du tube endotrachéal en vue de son insertion dans la trachée artère du patient.
