Definitions

  • the invention relates to a device for endotracheal intubation in the field of anesthesia and emergency medicine.
  • an endotracheal tube with a maximum inner diameter of 6.0 mm can also be placed over the standard laryngeal mask by means of a cumbersome procedure using a bronchoscope (Tonner et al., 1995), this procedure also has a number of disadvantages. It is a very troublesome and expensive procedure. You need a special bronchoscope and a light source. Due to the inner diameter of the laser mask shaft, it allows a maximum of a tube with an inner diameter of 6.0 mm, which is too small for adult patients. The removal of the laryngeal mask after intubation is associated with a high Extubationsgefahr.
  • a more practicable method of intubating the patient through a standard laryngeal mask is to use the COOK "Aintree” Intubation Catheter in conjunction with a special bronchoscope.
  • the "Aintree” Intubation Catheter is pulled over the bronchoscope and passed bronchoscopically through the laryngeal mask Trachea placed.
  • the tube After removal of the bronchoscope and laryngeal mask, the tube is advanced into the trachea via the "Aintree" Intubation Catheter, which serves as a guide bar
  • the "Aintree" Intubation Catheter which serves as a guide bar
  • significant disadvantages of this method are the high acquisition costs for the bronchoscope and the risk of damage to the bronchoscope glass fibers due to kinking in the area Transition to the bronchoscope handle, a site of predilection for fiberglass damage when using the Aintree Intubation Catheter.
  • a blind intubation without Due to the length of the "A ⁇ itree" catheter (56 or 83 cm), a bronchoscope with an above-average length (at least 60 cm) is required, since otherwise the controllability of the bronchoscope is not given.
  • a larynx mask with a mask part, a shaft and an intubation tube
  • the shaft has a patient-near tubular portion and an adjoining designed as an open guide rail section
  • the intubation tube through the shaft and through the mask member longitudinally displaceable and can be fixed by inflating a tube cuff in the tubular portion near the patient of the shaft.
  • the device according to the invention enables the first securing of the airway via the laryngeal mask function and, if required, fast, simple and cost-effective endotracheal intubation, in that a standard intubation tube constitutes a functional component of the laryngeal mask.
  • a standard intubation tube constitutes a functional component of the laryngeal mask.
  • This has no usable for ventilation shaft without the intubation tube. Rather, the intubation tube is inserted into the shaft of the laryngeal mask prior to insertion of the device into the larynx region of the patient and fixed by inflating the tube cuff in a near-patient tubular portion of the shaft.
  • This section has on the side facing the tongue base preferably means that prevent slipping out of the inflated tube cuff from the shaft, z. B.
  • the intubation tube thus fixed in the shaft at the same time seals the mask part to the outside. After insertion of the device into the larynx region of the patient, the latter can be supplied with oxygen as usual via a ventilation system connected to the tube connector. The intubation tube thus completely assumes the function of the normal laryngeal mask shaft. If necessary, z.
  • a normal standard bronchoscope or intubation catheter suitable for "blind" endotracheal intubation can be used Then the tube cuff is unblocked and the intubation tube is advanced over the now serving as a guide bronchoscope or the intubation catheter into the trachea of the patient and fixed there by re-inflation of the tube cuff.
  • the patient may be first ventilated as needed before removing the remainder of the lens mask, ie, mask portion and shaft, in order to reduce the risk of extubation in removing the now unneeded portions of the laryngeal mask.

  • a decisive advantage of the laryngeal mask according to the invention is the possibility of use on small children from a body weight of about 8 kg.
  • the previously used intubation laryngeal masks can only be used in children with a body weight of about 30 kg. Furthermore, no special expensive and fracture-prone bronchoscope such.

  • Another advantage of the laryngeal mask according to the invention is the replacement of the tubular ventilation system which is functional for ventilation. rynxmaskenschaftes by a commercially inexpensive and area-wide stockpiled endotracheal tube. Compared to the currently existing corresponding methods, the z. T. complex action sequences, the use of the laryngeal mask according to the invention allows a faster and safer endotracheal intubation. Iatrogenic errors during intubation can thus be avoided and material and personnel costs can be reduced.

Abstract

Masque laryngé présentant une partie formant masque (10), une tige (18, 22) et une sonde d'intubation (26), caractérisé en ce que la tige (18, 22) présente une partie tubulaire proche du patient (18) et une partie (22) se raccordant à celle-ci et conçue en tant que rail de guidage ouvert. La sonde d'intubation (26) est déplaçable dans le sens de la longueur à travers la tige (18, 22) et à travers la partie formant masque (10) et peut être fixée en gonflant le ballonnet de sonde (28) dans la partie tubulaire proche du patient (18) de la tige (18, 22).
