Definitions

  • the invention relates to an endotracheal cannula with an outer cannula, an inner cannula arranged inside the outer cannula, a holding element located at the exotracheal end of the outer cannula for fastening the endotracheal cannula to the neck of the tracheotomized patient and means for fastening the inner cannula and outer cannula.
  • Such endotracheal cannulas with a removable inner cannula are known (DE 38 13 705 AI). Such two-part endotracheal cannulas serve to keep the trachea open after tracheotomy or after resection or partial resection of the larynx in order to ensure breathing. To clean an inner cannula clogged with mucus, it is removed from the outer cannula and, after subsequent cleaning, inserted back into the outer cannula. A holding element is used for the permanent attachment of the outer cannula to the neck of the tracheotomized person, which as a rule has lateral openings for attaching a band or the like which is guided around the neck.
  • the inner cannula and / or outer cannula have appropriate fastening and securing means at their exotracheal ends, such as, inter alia, bolts or bayonet-type locking mechanisms (for example WO 93/23103).
  • the well-known endotracheal cannulas are available in a wide variety of sizes and designs, they are made from a wide variety of materials such as silver, stainless. Steel or plastics such as PVC, silicone, Teflon, polymers, etc.
  • Endotracheal cannulas which are equipped with a so-called speaking valve, are known for patients in whom the air-current connection between the trachea and larynx is still present, but has been temporarily interrupted, for example by a partial resection of the larynx, i.e. in which the vocal tract is still fully or partially preserved (GH-PS 581 464).
  • Such known endotracheal cannulas have one or more openings in the upper third of the arch of the cannula lying in the trachea.
  • the speaking valve is designed so that the air flow is passed through the valve opening when inhaled, but is passed through the closed valve through the openings in the upper third of the cannula through the larynx and causes the vocal cords to vibrate, so that To enable speaking.
  • the inner cannula has an exotracheally arranged valve chamber into which a valve disk, which is pivotably mounted on an outer plate, can be moved to open the valve, as is clearly evident from CH-PS 581 464.
  • valve bodies which is inserted into a dovetail guide.
  • These valve devices which mostly consist of silver, are attached to a ring of the outer cannula with a small chain to protect them against loss.
  • the known valve devices can only be removed with the aid of a mirror and by removing the speaking valve device together with the entire inner cannula. Both require a high level Skill of the patient or a helper.
  • a disadvantage of all known endotracheal cannulas described above is that the connection and thus also the release mechanism between the outer and inner cannula is neither designed uniformly nor does it allow smooth or emergency handling.
  • the invention is therefore based on the object of designing and developing the endotracheal cannulas mentioned at the outset and described in more detail above so that the aforementioned disadvantages are reliably avoided and safe handling is reliably ensured.

  • the end of the endotracheal cannula according to the invention protruding beyond the holding element of the outer cannula is extremely small, and when it is designed as a speaking cannula, the valve housing is displaced into the cannula interior so that the valve plate can freely swing into the widening of the inner cannula.
  • the angle of the widenings on the outer cannula and inner cannula is between 10 and 30 °, preferably 20 °. In this way it is reliably ensured that even at same size angle can be produced by a different length of the widened area of outer and inner cannula different sized endotracheal cannulas, which, however, can be connected with uniformly large holding and adapter elements.
  • the endotracheal cannula according to the invention is fully functional even without exotracheal widenings on the inner and outer cannula.
  • the inner cannula and the adapter elements are preferably connected to one another in a form-fitting manner in a further embodiment of the invention.
  • the connection can be made by means of a bayonet-type engagement behind locking elements formed on the inner cannula in corresponding recesses in the holding element.

  • an additional securing ring can also be used for the connection of the inner cannula and the adapter element, which firmly connects the exotracheal end of the inner cannula to the adapter element.
  • a preferred embodiment of the invention also provides that the outer cannula is additionally fastened to the holding element by means of a securing element.
  • the securing element is arranged on the neck side and is largely flush with the underside of the holding element.

  • the cannula can be completely disassembled into its individual components, cleaned, sterilized and then reassembled.
  • the viewer also gets a picture of cleanliness and regularity that is not pronounced of an auxiliary device but rather of a piece of jewelry.

  • the adapter element can also have a valve cover, so that the endotracheal cannula according to the invention can simultaneously be used as a speaking cannula.
  • the valve cover In the open position, the valve cover can protrude into the interior of the inner cannula. It is particularly expedient if, in a further embodiment of the invention, the outer surface of the valve cover in the closed position is flush with the outer surface of the adapter element, in order to develop the advantages already mentioned with regard to hygiene and aesthetics even with speech cannulas.

  • valve cover can be removed from the adapter element.
  • This embodiment also supports the modular or partial module-like structure of the endotracheal cannula according to the invention, since the patient no longer has to purchase two different inner cannulas for the versions with and without a speaking valve.

  • the fact that according to the invention there are no longer any rigid connections between the individual cannulas and the associated holding devices means that there are no longer any dangers in use, ie in carrying the endotracheal cannula according to the invention.
  • the system of the endotracheal cannula according to the invention leads to a standardization, since the production will be less expensive than the previously known designs. Damaged cannula parts can be easily replaced thanks to the modular or partially modular structure, without the entire cannula having to be sent in or replaced completely for repair. Switching from a metal cannula to a plastic cannula is also straightforward with the endotracheal cannula according to the invention, since only the desired parts always have to be ordered, i.e. only the plastic tubes have to be bought in as replacements for the metal tubes and vice versa.
