Definitions

  • This invention relates to a modification of conven ⁇ tional endotracheal tubes which facilitate intubation into the tracheo-bronchial (TB) tree.
  • the tip of the tube may enter the larynx at some distance from the path taken by the introducer and the bevel may catch on the vocal cords or arytenoid cartilages thus preventing its own passage between the vocal cords.
  • a bevelled tube of uniform diameter may be very difficult to mani ⁇ pulate through the nose and into the oropharynx and trauma may be caused by the tip of the tube to the posterior nasopharyngeal wall.
  • an aim of present invention to provide an endotracheal tube which may be easily introduced to the TB tree after insertion of a pilot member.
  • an endotracheal tube having at its leading end locat ⁇ ing means for locating the tube for sliding movement relative to an elongate pilot member which has previously been introduced into the tracheo-bronchial tree, thus facilitating insertion.
  • the locating means are constituted by a terminal orifice defined by a tapered end portion of the tube, the tapered portion being provi ⁇ ded with one or more ports or other forms of orifice to permit the passage of gases.
  • the locating means may be an annulus set within the end portion of the tube or indeed any formation which can partly or completely embrace the pilot member.
  • the locating means are constituted by an end portion of the tube having terminal portions which overlap in the circum ⁇ ferential direction.
  • Figure 1 is a perspective of the leading end of an endotracheal tube according to the invention
  • Figure 2 is a similar view of a modification of the tube of Fig. 1;
  • Figure 3 is a detail in axial section through an end portion of the tube of Fig. 1.
  • An endotracheal tube 10 has a leading end as shown in Fig. 1 comprising a uniform diameter portion (which may be any type of endotracheal tube and may be cuffed) which tapers through an intermediate portion 14 to define a small diameter terminal orifice 16 which is coaxial with the body portion 12.
  • a lobe-shaped port 18 is formed in the intermediate portion 14.
  • a flexible elongate pilot member conveniently a fibroptic endoscope 19 (see Fig. 3) , which is an easy sliding fit in the orifice 16 is first passed through the body portion 12 and orifice 16.
  • the pilot member is then negotiated down the TB tree until it extends well beyond the desired limit of insertion of the tube 10. It is then an easy matter to slide the endotracheal tube 10 down the inserted pilot member, and then to withdraw the pilot member.
  • the tube 20 having a body portion 22 and shown in Fig. 2 is inserted in a similar way, but differs structurally from the tube 10 in having a tapering end portion 24 and a terminal orifice 26 which are coaxial with the body portion 22, and two ports 28 formed in the tapering portion 24.
  • the end portion 14 of the endotracheal tube 10 is formed so as to present a smooth transition between the surface of a tapering end portion 14 and the surface of a fibroptic endoscope 19.
  • the tube 20 has a similar terminal configuration and details of the ports have been omitted.
  • An endotracheal tube may go down the right main bronchus or the left main bronchus which is a matter that is routinely monitored during intubation; the side ports of tubes according to the present invention should ensure the venting of both lungs, especially if the tube is stabilised in the trachea by having the inflated cuff very close to the tapered terminal portion.
  • Friction on the pilot member is kept to a minimum by having only a very short terminal length of the tube of minimum internal diameter; a lubricant may be used to facilitate sliding the tube over the pilot member.
  • the terminal orifice does not necessarily have to be perpendicular to the longitudinal axis of the tube as shown in the drawings, and may be inclined so as to form a miniature bevel.
  • Provision of one or two side ports may facilitate removal of a pilot member having a highly angulated terminal portion by allowing the elbow of the pilot member to be received in a port.
  • the terminal tapered portion of the endotracheal tube may be formed as a spiral, for example a continuation of the helical wire reinforcement of an armoured tube.

Abstract

Un tube endotrachéen (10) comporte une partie terminale conique dotée d'une ouverture (18) et définissant un orifice (16) de faible diamètre. Afin d'insérer le tube (10), on fait d'abord passer un élément pilote tel qu'un endoscope à fibre optique dans la partie de corps (12) et l'orifice (18) avant de négocier son passage dans l'arbre trachéo-bronchique du patient. On fait ensuite glisser facilement ledit tube (10) dans ledit élément pilote inséré que l'on retire ensuite. On a mis au point un autre moyen de localisation de l'extrémité du tube endotrachéen par rapport à l'élément pilote, et permettant le passage de gaz.
