Description

The The invention relates to a holder for speaking valves and / or Heat-moisture exchangers used in tracheostoma patches or tracheal cannulae finds application.

Out US 4,325,366 a speech valve is known, which is attached by means of a double-sided adhesive plaster around the stoma of the patient, wherein the entire valve is inserted into a drum-shaped receptacle. The valve is releasably fixed solely by clamping friction in a drum-shaped receptacle.

A comparable recording is from the company HEIMOMED Heinze GmbH & Co. KG under the name PRIM-AIR-STRIP, where also there interchangeable speaking valves and / or heat-moisture exchangers in a likewise drum-shaped elastic recording almost be completely pressed. An additional Groove, which is in a corresponding counterpart of the valve or the heat-moisture exchanger housing carrying engages, provides here for an additional backup said assemblies against accidental release and thereby for a firmer fit.

A comparable, but practically twice as far from the stoma protruding device for a likewise mounted by means of a double-sided adhesive tape heat-moisture exchanger is in EP 0387220 B2 described. There, a heat-moisture exchanger is snapped onto the upper edge of a funnel-shaped and glued to the stoma holding device by means of claws.

These Device has the disadvantage of a relatively high, spaced from the stoma Design and is therefore not sufficient aesthetic Aspects of the carrier.

In WO 99/29268 Finally, a speaking valve arrangement is described, in which a housing for receiving a heat-moisture exchanger and a valve is provided. This housing is also connected to a holding device, which is glued in a known manner to the stoma, here, in contrast to the devices described above, the entire, the speaking valve and a heat-moisture exchanger receiving housing only at the bottom of this housing over a circular circumferential the proximal housing end rib, which engages in a groove-shaped, attached to the adhesive tape holder is supported.

at This type of holder can make it relatively easy to unintentionally Loosen the valve body come.

In the EP 1787671 A2 The invention relates to a holder for speaking valves and / or heat-moisture exchanger for tracheostoma or tracheostomy tubes.

The Task, such a holder for Laryngetomierte or Tracheotomized specify, on the one hand a very tight fit when installed and a flat design and on the other hand a ensures easy interchangeability by the patient, is solved by a housing on or in the region of its proximal end, intimately with at least two noses or at least one bridge is provided in the / the hook, the are provided in the bottom region of a retaining ring, by rotation intervene, being between the proximal contact surfaces of the housing and congruent to these provided bearing surfaces of the Retaining rings in mutually braced condition of housing and retaining ring sealing surfaces are formed.

All the above device, except EP 1787671 , in common is that they do not ensure a secure fit of the speaking valve and / or heat-moisture exchanger, as for example. Significant pressures occur when coughing or sneezing of the patient, which can easily reach hurricane force, whereby the valves are literally thrown away.

To on the latter speaking valve, the known designs additionally the disadvantage that they are when changing, for example, for cleaning purposes or replacement of the heat-moisture exchanger, for the patient relatively difficult to remove, because the main part of the housing circumferentially detected by the holder is.

In the EP 1787671 A trained bayonet lock is used, which is locked with the cross-links in the HME and speaking valves.

The Locking and Endriegeln are complicated.

Of the Invention is therefore based on the object, a holder for Speech valves and / or heat-moisture exchanger for Laryngetomierte or Tracheotomierte indicate, on the one hand a very tight fit when installed and a flat design and on the other hand ensures a problem-free interchangeability by the patient.

The task is characterized by the characteristics of Patent claim 1 solved.

advantageous Further training are of the subordinate claims detected.

The inventive bracket is characterized from that the bracket for speaking valves and / or heat-moisture exchangers, in the form of a substantially U-shaped housing, the the speaking valve and / or the heat-moisture exchanger carries, respectively receives, with the housing provided innwändig with a groove in U-shape, in the the external profiles of the HME and speaking valves be inserted laterally and clamp by narrowing the groove, being between the proximal abutment surfaces of the housing and congruent to these provided bearing surfaces of the U-shaped housing braced against each other Condition of housing and U-shaped housing Sealing surfaces are formed.

Across from known holders for the same purpose, the Solution according to the invention pronounced comfortable handling for the patient. This one can the complete speaking valve and / or the heat-moisture exchanger insert and remove by simply inserting it sideways What happened for cleaning purposes or filter change several times a day whereas, in the locked state, it must be absolutely secure Locking is guaranteed.

Thereby, that almost the entire housing wall of the speaking valve and / or the heat-moisture exchanger with the fingers can be detected, the housing from the carrier of this component easily accessible with two fingers.

The Invention will be described below with reference to embodiments and schematic drawings explained in more detail become.

In the 1 is schematically illustrated a first training possibility of the holder according to the invention in a plan view and side view.

There is initially essentially a U-shaped receptacle ( 4 ), in which a speaking valve or a heat-moisture exchanger as an assembly part ( 9 ) are insertable.

The Speech valve would be in unspecified upper receiving zone and the heat-moisture exchanger would be completely put into the recording.

There these two modules by the invention but no further embodiment was learned, for clarity waived their detailed representation.

In the context of the invention is essential that the U-shaped receptacle ( 4 ) for inserting the component ( 9 ) with a groove ( 6 ) is trained.

The component ( 9 ) will be replaced by the introductory phase ( 7 ) and into the groove ( 6 ).

When inserting the component ( 9 ) to the U-shaped arch ( 16 ) prevents the locking knob ( 5 ) slipping out of the component ( 9 ) out of the groove ( 6 ).

When inserting the component ( 9 ) is applied via the sealing surface phase ( 13 ) the component ( 9 ) on the sealing surface ( 12 ) pushed. In this area a clamping between groove ( 6 ) and component part ( 9 ) as well as a sealing of the component ( 9 ) with the sealing surface ( 12 ) reached.

The component ( 9 ) is about the Stomaloch ( 11 ) in the plaster ( 1 ) placed centrically. The protective foil ( 3 ) is removed from the plaster ( 1 ) and the plaster ( 1 ) by means of an adhesive layer ( 2 ) about the Tracheostomy glued to the skin.

The entire bracket is fitted with a welding ring ( 10 ) integrally formed, which in turn cohesively with the plaster ( 1 ) connected is.

The above-described facts regarding sealing and clamping in the groove ( 6 ) is from the 2 indicating the placement of a speech valve and / or heat-moisture exchanger as a component ( 9 ) clearly shows.

The diameter measure ( 15 ), the height ( 14 ) and the clamping dimension ( 17 ) are dimensioned such that upon granting the sealing and holding function existing speaking valves and / or heat-moisture exchanger as mounting parts ( 9 ) can be applied.

In the context of the invention, the welding ring ( 10 ) and the recording ( 4 ) made of a stiff and less elastic material, such as polypropylene, polycarbonate, SAN or PS, where quite the sealing surface ( 12 ) can be equipped with an elastic additional sealing ring.

Other, common in medical applications for the intended purpose Of course, materials are also included the invention.

At the same time is in 1 the attachment of the welding ring ( 10 ) on a pavement ( 1 ) indicated.

For this purpose, the recording ( 4 ) is formed so that the welding ring ( 10 ) in a round flange, which is connected to the plaster ( 1 ), which is taped over the stoma, not shown, is welded.

The welding ring ( 10 ) made so thin that it has sufficient elasticity.

In the context of the invention, the welding ring ( 10 ) and the recording ( 4 ) with all its components, in particular with the U-shaped groove ( 6 ) Advantageously formed by a one-piece molded part.

As regards the recording ( 4 ) and the type of attachment of the HME is no restrictions on the use of this holder, as a precaution mentioned that the recording of course, the distal receiving area of a cannula, whether outer or inner cannula, can form.

Already known speaking valves and / or heat-moisture exchangers, which are housed in cylindrical housings, have almost consistently a lower round edge in the form of an annular bead ( 18 ) (like 2 seen light), which is intended only to lock the heat-moisture exchanger in a ring.

Advantageously, the annular bead ( 18 ) for the here provided type of housing lock in the U-shaped groove ( 6 ), without the need for special further transformations of these operations.

Preferably, but not limiting the invention, in these cases, a U-shaped groove ( 6 ) provided for the lateral insertion of housings.

For deviations of the annular beads ( 18 ) and housing diameter can in the example also a customized U-shaped groove ( 6 ) are provided for insertion, but this somewhat complicates the ease of use and replacement of the housing by the patient.
