Definitions

  • the invention relates to a tracheostoma closure according to the preamble of claim 1.
  • a closure is known from DE-GM 83 29 888 and the same DE-OS 34 36 777.
  • patients with a tracheostoma ie an artificial opening leading into the airway in the neck area, can speak in a known manner with the help of a speech or voice prosthesis, which is operative as a connection between the airway and the foodway is used.
  • the tracheostoma must then be closed to speak.
  • patients usually use a finger, which is placed on the opening and prevents the air from escaping at this point.
  • the above-mentioned from the documents known tracheostomy closure provides a proven solution for the 'explained issues. It enables a simple and secure attachment and easy handling by the patient ten.Es are but improvements desirable.
  • the invention is accordingly based on the object of further developing the known tracheostoma closure in such a way that a greater air throughput with a lower overall height and further improved attachment and handling is made possible.
  • the solution to the problem is specified in claim 1.
  • the valve flap enables a large passage cross-section with good and reproducible sensitivity.
  • valve flap and / or its seat made of resilient material, such that the flap after
  • Closing can pass through its seat if the specified dynamic pressure is exceeded. This special training ensures the necessary safety, because a sudden breath, for example when coughing, must always be possible.
  • the valve flap once it has passed through its seat, can be pushed back into its normal position by hand without removing the closure.
  • the security feature can also be implemented in a manner known per se in that the valve housing is plugged onto the cannula stub and can then be coughed up or removed if necessary.
  • the valve flap can be mounted in the lower region of the valve housing in the operating position and can be held in the open position by an additional weight.
  • the valve flap only fulfills its non-return function when a certain flow rate is exceeded during breathing, i.e. the patient wants to close the valve flap arbitrarily by a sudden breath in order to speak.
  • the valve flap can have a magnet which interacts with a further magnet on or in the wall of the valve housing and holds the valve flap in the open state. Magnet should be understood to mean that at least one component of the interacting pair is a permanent magnet.
  • the other component can consist of soft magnetic material, for example an iron plate.
  • a further possibility of keeping the valve flap in the open state up to a certain outflow speed is to urge the flap into the open position by spring force.
  • the spring force can be achieved by mounting the flap itself, for example in the form of a film hinge, or by a separate spring.
  • a development of the invention provides that the bearing point of the valve flap can be displaced in the circumferential direction of the cannula stub.
  • the effective gravity component can then be changed, and in the case of magnets, the displacement of the bearing position changes the magnetic force by changing the opposing effective surfaces of the magnets.
  • valve housing is plugged onto the cannula stub and can be rotated against it.
  • the cannula stub unites in the area of its contact surface with the valve housing has surrounding web. The inner edge of the valve housing then slides on the narrow web instead of on the entire contact surface.
  • a circumferential web can also be arranged in the area of its contact surface with the cannula stub, which snaps behind the web when the valve housing is pressed onto the cannula stub.
  • One of the circumferential webs can also have interruptions without impairing the tightness.
  • valve housing can also be in one piece part of the cannula stub.
  • valve flap is in the form of a thin disc which is connected via a film hinge to a radial extension which is sealingly inserted through a slot in the wall of the valve housing and preferably has a stop which defines and limits the insertion depth.
  • the slot in the circumferential direction of the valve housing can be so wide that the extension of the valve flap can be adjusted in its angular position.

  • an individual shape adaptation of the flange ring to the anatomical conditions is possible.
  • the flange ring can be provided with a radially projecting tab with a bore, which enables the attachment of a band leading to the removable valve housing. The valve housing is then secured against loss. Instead, the valve housing can also be fastened to a radially projecting tab of the cannula stub with a band.
  • the flange rings can then be formed symmetrically so that they are easier to handle by the patient.
  • the closure member consists of a flange.
  • the closing member is a piece of pipe attached to the inner end of the cannula stub and open towards the cannula stub. This presupposes that the trachea is not in the otherwise is usually guided under bending to the stoma, but that the trachea receives a cover after the larynx has been removed and the stoma is guided laterally into the trachea. This also enables a large-lumen stoma with a correspondingly large cross-section of the closure. '

Abstract

Une fermeture pour trachéotomie comprend une soupape (18, 23) volontairement actionnable lors de l'expiration, ce qui permet à la personne de parler. Une section de canule (10) ouverte et introduisible dans l'ouverture de la trachée comprend un bout de canule (7) qui traverse l'ouverture et s'ouvre à l'extérieur, portant sur son côté antérieur un boîtier (9) pour la soupape. Un anneau de bride (8) ajustable entoure le bout de canule (7) et rend étanche l'ouverture de la trachée. La soupape est formée d'un clapet de non-retour (18) agencé de façon pivotable dans le corps (9) de la soupape qui s'ouvre pendant l'inspiration et se ferme pendant l'expiration lorsqu'une vitesse prédéterminée d'écoulement est dépassée.
