Definitions

  • This invention relates to an intubation device, preferably a nasal endotracheal intubation device, and method of use thereof.
  • the invention relates, but is not limited, to the safe and effective placement of an endotracheal tube through a nasopharynx of a patient and therefore will be described in this context.
  • other tubes may be placed through orifices using the intubation device and method.
  • Endotracheal tubes are a popular method for the administration of inhalational anaesthetic agents nto the lungs. These tubes are normally used for either oral intubation or nasal intubation. Oral intubatio is the generally preferred method of intubation as the endotracheal tube can be easily placed through the oropharynx, iaryngo pharynx, and the vocal chords when a patient's head is tilted backwardly. Endotracheal tubes typically have a ' bevelled edge to allow the endotracheal tube to be passed easily through the vocal chords without damage.
  • the bevelled end of the tube may traumatise the mucosa of the turbinates, tonsils, and/or the adenoids to precipitate haemorrhaging.
  • Haemorrhaging may cause the lumen of the endotracheal tube to be covered in blood and cause the lungs to be soiled due to positive pressure ventilation forcing blood from the lumen into the lungs.
  • Biood and secretions/tissue from the nasopharynx may also block the lumen of the endotracheal tube.
  • Another problem with nasal intubation s the difficulty in passing the endotracheal tube through the tortuous nasopharynx which delays intubation.
  • the diff iculties in passing the endotracheal tube through the nasopharynx is due to a number of factors including the bevelled end of the endotracheal tube, the diameter of the endotracheal tube, and the lack, of flexibility of the endotracheal tube. Failure to pass the endotracheal tube quickly into the lungs results in lightening of the anaesthesia which is undesirable as laryngospasm may be precipitated with contact of the endotracheal tube with the vocal chords.
  • the endotracheal tub is often softened by locating the endotracheal tube within warm water, known as thermosoftening, prior to passing the endotracheal tube through the nasopharynx.
  • thermosoftening locating the endotracheal tube within warm water
  • heating of the endotracheal tube is time consuming and in life or death situations, heating the endotracheai tube is not always a viable option.
  • a further solution is to use an introduction device, such as a red rubber, Jacques or modified Foleys catheter, with the flute of the proximal end of the catheter protectin the end of the endotracheal tube.
  • an introduction device such as a red rubber, Jacques or modified Foleys catheter
  • the flute of the proximal end of the catheter protectin the end of the endotracheal tube.
  • modified endotracheal tubes have been developed with a longer flexible tip in an attempt to minimis trauma.
  • this can reduce the effectiveness and efficiency of the endotracheal tube.
  • Other known attempts to overcome these problems include using the finger of a iatex glove or using an inflatable balloon to cover the tip. Such approaches can introduce further complications, particularly if the latex glove finger or inflatable balloon becomes loose or separates from the endotracheal tube.
