• - secretion suction from the deeper respiratory tract in severe pulmonary or neurological diseases,
• - In the case of recurrent airway obstruction in the area of the pharynx or the larynx, as in the case of obstructive sleep apnea, impaired glottic motor activity or radiation-induced Verschwellung.

As well can the solution according to the invention in Special applications, such as inhalation obstructions, e.g. in double-sided Vocal cord paralysis, Find employment.

It Various Tracheostomaplatzhalter are known. For example, a so-called "Barton-Mayo Tracheostoma Button "that off a one-piece Part consisting of a valve holder, a tracheostomy flap and one imprintable in the stoma button-like, concentric conclusion exists.

This Platzhalter has the disadvantage that it is the respective anatomical Special features adaptable only by a special new production would be, about none has particularly good sealing effect and especially in the patient by a relatively sharp-edged plant on the neck skin leads to swelling and pain.

at other known spacers (e.g., U.S. Patent 4,269,184) seek to thereby improving the tracheal-side abutment of the spacer, that at the tracheostoma ashes diametrically opposite two equal length, flap-like systems are provided. Also put these rags no safe attachment to the trachea and are very easy to Dislocation.

all known Tracheostomaplatzhaltern for sealing a temporary Tracheaeröffnung and providing safe access to the trachea in common, that the wearing characteristics in the patient as unpleasant be felt.

Farther are for other applications, namely for the Valve seal of the trachea stump after a total larynx removal, tracheostoma occlusions off DE-U-85 14 859 and US Pat. No. 5,683,458.

A Zuführmöglichkeit eg a breathing cannula or a breathing tube is not possible with these solutions.

Finally is off DE 59710934 a tracheostomy site holder is known which attempts to remedy the above-mentioned problems of tracheostoma site owners.

This consists of a tubular Tracheostoma at one side in one piece and in a first dimension arched Trachealschenkel expires the tracheal limb being perpendicular to the first dimension extending dimension to the Tracheostomaschenkelachse such is connected, that he has different lengths overhang areas, where the tracheostoma at the side of the tracheal branch End is providable with a closure means, the overhang areas thinned with several Tracheal leg sections to provide according to the teaching there are assigned, and the Tracheostomaschenkel interrupted locking means These are the inclusion and fixation of a shield in a variably customizable Distance to the contact surface tracheal limb to the trachea.

The latter is by the provided, attachable at a fixed distance Locking means only conditionally possible. Furthermore This design is also perceived by the patient in comfort as pleasant and leads due to the there provided way of edged Rastmittelausbildung even inflammation in the tracheostoma.

Incidentally, are Such ribs from so-called T-tubes for a comparable purpose known for decades, so the essence of the above quoted Invention in the differently long trained and with thinning provided overhang areas should exist.

present The invention is therefore based on the object, a Tracheostomaplatzhalter for sealing a temporary Trachea opening and Creating a secure access to the trachea to solve the disadvantages of the prior art, a ensures safe and largely self-sealing seat in the trachea opening and an additional one Tracheostomy seal ensured.

The The object is solved by the features of claim 1.

advantageous Further training is covered by the subordinate claims.

The Invention will be described below with reference to an embodiment and schematic Drawings closer explained become.

It demonstrate:

1 : An embodiment of a tracheostoma tray holder with the components essential to the invention in a perspective view

2 : on the left the training of a spacer mother 1 with thread in cut side view and right in plan view

3 : the formation of a Tracheostomaschenkels with adjoining Trachealschenkeln in lateral view and right next to it in the vertical lateral section

4 : in a side view, the sealing plug with a spacer nut locking ring on a strand.

In 1 is a tracheostoma plate holder ( 1 ) according to the present invention in a perspective view, which consists of a Tracheostomaschenkel ( 9 ) and tracheal legs ( 2 ) consists; both parts preferably form an integral unit.

In contrast to the known state of the art, the tracheostoma ashes ( 9 ) substantially a cylindrical surface, free from discontinuous, sharp-edged profiles, on. On this tracheostoma ashes ( 9 ) is a thread to the comprehensive, stepless, fine moving the spacer nut ( 3 ) to the tracheal limb ( 2 ).

Out 1 It can also be seen that a sealing cone ( 10 ) the tracheostomy when turning the spacer nut in the direction of tracheal limb ( 2 ) seals.

It can also be seen that one with a stopper ( 5 ) provided strand ( 6 ), wherein a Distanzmutterarretierungsring ( 4 ) With ( 5 ) and ( 6 ) is manufactured as a preferably one-piece, injection-molded unit.

Furthermore, it is provided in the context of the present invention that the off-patient end of Tracheostomaplatzhalters ( 1 ) with a securing means ( 7 ). This securing means prevents the spacer nut ( 3 ) may be mistakenly accidentally inserted into the stoma prior to final placement.

In the context of the invention, it is particularly advantageous to use this securing means as a retaining ring ( 7 ), which in one operation to the tracheostomy ( 9 ) is molded with and thus also a one-piece element of Tracheostomaplatzhalters.

When inserting into the stoma with the help of this circlip ( 7 ) an uncontrolled slipping of the tracheostoma tray holder into the stoma in case of accidental removal of the spacer nut ( 3 ) and in the case of poor placement, the tracheostomy site holder ( 1 ) so that it can be easily removed again.

After the tracheostomy site holder ( 1 ) is positioned exactly, there is no further need for additional security and the retaining ring ( 7 ) can be easily cut off.

Further protection against loosening or unscrewing the spacer nut ( 3 ) is through the spacer nut ( 4 ).

The spacer nut retainer pinches on the thread ( 8th ) and prevents twisting of the spacer nut from the stoma.

The special training of the spacer nut ( 3 ) is in 2 shown in detail.

In the left part of the figure, the spacer nut is shown in section. It can be seen that the sealing cone ( 10 ) consist of a solid material and a piece for the stoma and the spacer nut itself.

in the Contrary to the known state of the art, no additional separately to be attached straps necessary, which additionally increases the wearing comfort for the patient, this possibility but does not exclude.

in the Example, best results with the motion thread in application the spacer nut when locking the Tracheostomaplatzhalters scored in the stoma. By the movement thread can be a fine adjustment in terms of Clamping patient side done individually.

The is supported by that the Tracheostomaschenkel of soft, elastic material and the spacer nut are made of hard plastic material.

It does not rule out that the thread sentence ( 11 ) made of hard material and the entire spacer nut ( 3 ) and / or sealing cone ( 10 ) are made of soft, elastic material.

Essential is that also in contrast to the prior art, a closed Movement thread is circumferentially closed in itself and no too Leading injury breakthroughs or sharp edges.

The also offers advantages when cleaning the placeholder.

Likewise in contrast to known forms of implementation according to the prior art, it is not necessary to offer tracheostomy flaps of different lengths here, but by attaching the plug ( 5 ) on the strand ( 6 ) with the Distanzmutterarretierungsring ( 4 ) is the tracheostoma ( 9 ) individually adapted to the patient shortened and the plug ( 5 ) ensures close to the stoma for the closure of the outwardly open Tracheostomaschenkels.

With the Tracheostomaplatzhalter created is thus a device for multi-valued applications before, which takes into account the anatomical features of the patient and ensures a safe and comfortable fit. By the described type of formation of the sealing cone ( 10 ) causes this in the deferred state an additional outer Tracheostomaabdichtung and its conically rounded rounded shape (Ke) and the movement thread ( 8th ), even if they partially protrude into the tracheostoma, cause no inflammation in the stoma.

All in the description, the embodiment and the following drawings discernible features can both individually as well as in any combination with each other invention essential be.
