Description

The invention relates to a holder for speaking valves and / or heat-moisture exchanger and suitable heat-moisture exchanger, which is preferably used in tracheostoma and tracheal cannulae application.

After a larynx removal increased respiratory problems may occur because due to the broken connection between the nose and lungs eliminates the functions of the nose. The breathing air is no longer filtered, warmed and moistened. This leads to irritation of the bronchial mucosa, excessive secretion production and thereby to increased cough.

In addition to heating, humidifying and filtering respiratory air, natural nasal breathing also provides respiratory resistance, which is important for oxygenation in the blood.

The lower resistance after laryngeal removal lowers the oxygen concentration in the blood. For the person concerned, this shows in the form of fatigue, depression and diminished performance.

The humid heat exchangers are intended for patients with spontaneous breathing and are usually attached to a universal cone of a tracheostomy tube or a tube and serve for pulmonary rehabilitation. The moisture-heat exchangers remove the moisture and heat from the exhaled air of the patient and lead them back to the patient via the inhaled air.

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 sold by the company HEIMOMED Heinze GmbH & Co. KG under the name PRIM-AIR-STRIP, where also interchangeable speaking valves and / or heat-moisture exchangers are almost completely pressed into a likewise drum-shaped elastic recording.

An additional groove, which engages in a corresponding counterpart of the valve or the heat-moisture exchanger supporting housing, here provides additional backup of said assemblies against accidental loosening and thus 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.

This device has the disadvantage of a relatively high, spaced from the stoma design and thus does not meet aesthetic aspects of the wearer.

In WO 99/29268 a speech valve assembly is described in which a housing is provided for receiving a heat-moisture exchanger and a valve. 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.

In this type of holder, it may be relatively easy for unintentional release of the valve housing.

All the above devices have in common that they do not ensure a secure fit of the speaking valve and / or heat-moisture exchanger, as, for example, when the patient coughs or sneezes significant pressures occur that can easily reach hurricane force, causing the valves are literally thrown away.

Apart from the last-mentioned speaking valve, the known designs additionally have the disadvantage that they are relatively difficult to remove when changing, for example, for cleaning purposes or replacement of the heat-moisture exchanger, because the main part of the housing is circumferentially captured by the holder.

The latter problem is caused by an in EP 1 787 671 B1 described apparatus is provided in which a substantially cylindrical housing which carries the speaking valve and / or the heat-moisture exchanger, respectively receives, is provided, wherein the housing at or in the region of its proximal end inwändig provided with at least two lugs or at least one web is, in the hooks, which are provided in the bottom portion of a retaining ring, engage by rotation, wherein between the proximal contact surfaces of the housing and congruent to these provided bearing surfaces of the retaining ring in mutually braced state of the housing and retaining ring sealing surfaces are formed.

In this solution, the housing and the retaining ring and the hooks are made of a stiff and less elastic material and the retaining ring with a flange which is welded to the tracheostoma patch, provided, wherein the flange is in turn made so thin that it is elastic again , Although this solution guarantees a secure fit of the speaking valve and / or the heat-moisture exchanger on the tracheostoma and pleasant wearing properties in the patient, but still requires a relatively high production cost and a certain exercise of the patient when changing the exchanger.

In EP 0 959 927 B1 is described a respiratory protective equipment whose main objective is to provide a heat-moisture exchanger on a tracheostoma patch, which allows the lateral air leakage and thereby avoids contamination by adjacent garments on its front surface. For this purpose, said front surface is covered body side in an embodiment with a closed rigid plate and glued to the other side directly on the tracheostoma.

Since the surfaces of Tracheostomapflastern are profiled relatively strong, just as with conventional plasters, can be characterized by the in EP 0 959 927 B1 solution described sticking realize only a selective attachment of the heat-moisture exchanger, which does not guarantee a secure grip.

In addition, there is the danger in this solution that when pressing a new heat-moisture exchanger (more often required change) on the patient located on Tracheostoma plaster the heat-moisture exchanger is pressed into the stoma of the patient.

If such an embodiment is also to be used as a speaking valve, it is proposed in this document that the heat-moisture exchanger be cylindrical in such a way that it is received centrally by a short cylindrical piece, which is connected in a manner not described in more detail with the tracheostoma patches. This would give a function as a speaking valve when the local rigid cover plate is pressed onto the cylinder cone. Also, the cylinder cone is pressed into the stoma of the patient, which is likely to be perceived by this as extremely unpleasant.

In addition, from a slightly more distant state of the art, such as in DE 100 07 623 C1 . WO 94/01158 A1 and DE 20 2005 008 359 U1 described, solutions for mounting assemblies such as speaking valves and / or heat-moisture exchangers, known, but these relate solely to their attachment to tracheostomy tubes. Since in such compounds but relatively rigid partners (tracheostomy tube and the assembly to be mounted there) are connected to each other, there leakage problems play, in contrast to the attachment of said assemblies on Tracheostomapflastern, practically no role.

Furthermore, in the GB 20 2012 003 23.4 . 20 2012 004 539.3 . 20 2012 005 851.7 an adhesive HME is described on a fixed plate on a tracheostoma patches.

All described inventions have the disadvantage that a humidifying function with a speech function is not given.

The present invention therefore has for its object to provide a heat-moisture exchange device without housing with humidifying and speech function for laryngectomy or tracheotomy, which ensures on the one hand a tight fit of a heat-moisture exchanger and a flat design and on the other a problem-free interchangeability by the patient, wherein by pressing a spring element, a closure of the breathing opening can take place to initiate a speech process.

In addition, the solution according to the invention is an inexpensive production with a minimum of individual components, eg. B. without housing, and at the same time have a high level of comfort for the patient.

The object is solved by the features of claims 1 to 3.

Advantageous further embodiments are the subject of the dependent claims.

The holder according to the invention is characterized in that the holder for speaking valves and / or heat-moisture exchanger, an elegant and extremely flat design with high comfort and allows the patient a simple change of the heat-moisture exchanger without more complex manipulation outside its field of vision. At the same time ensures the inventive type of attachment of the heat-moisture exchanger its tight fit even at higher pressure loads (such as when coughing or sneezing) and by the elastic distal Surface training a pliable adaptation to worn over garments and so compared to the prior art considerably more aesthetic appearance.

Compared with known brackets for the same purpose, the solution according to the invention has a very comfortable handling for the patient. This can remove the complete speaking valve and / or the heat-moisture exchanger by simply removing it from the carrier, which must be done several times a day for cleaning purposes or filter replacement, whereas in the attached state an absolutely secure fixed locking is ensured.

The fact that the replaceable filter body itself, with the exception of the laminations and adhesive surface required here, in its basic version requires no further components, it can be made very cheap, so that in such an embodiment not even worth its cleaning.

In the context of the invention can also be used, elaborately constructed heat-moisture exchangers can be easily changed by the new way of their attachment to Tracheostomapflaster in the same way and can optionally be supplied for cleaning and reuse.

The invention will be explained in more detail below with reference to exemplary embodiments and schematic drawings.

In the 1 a heat-moisture exchanger is recorded, which by means of adhesive layer ( 6 ) on a plate ( 7 ) of a tracheostoma plaster ( 8th ) and by a pull tab ( 10 ) can be removed again. The airway ( 11 ) goes through the breathing opening ( 22 ), through the filter ( 16 ) and the filter cylinder ( 2 ) when opening the air opening ( 13 ).

The filters ( 16 ) 14 ) 2 ) are covered with a skin ( 5 ) on the surface.

The breath is moistened in this position.

In the inner core ( 14 ) as a filter is a spacer rod ( 3 ), the outside with a pressure plate ( 1 ) and in the breathing opening ( 22 ) with a sealing plate ( 9 ) is integrally connected. When exercising the finger pressure ( 17 ) on the printing plate ( 1 ) the filter cylinder ( 2 ) separated from the filter ( 16 ) through the sliding gap ( 4 ) pressed together until the sealing plate ( 9 ) on the sealing edge ( 12 ), the airway ( 11 ) and thus can initiate a patient's speech.

The air opening ( 13 ) is zero in this process.

Due to the spring action of the filter cylinder ( 2 ) the sealing plate ( 9 ) without finger pressure ( 17 ) so back that the air opening ( 13 ), the airway ( 11 ) and the patient through the breathing opening ( 22 ) can breathe freely.

The 2 shows a further variant that allows the application of the invention.

One with skin ( 5 ) on the surface of the filter ( 16 ) is by means of adhesive layer ( 6 ) to a cannula flange ( 18 ) glued.

The filter ( 16 ), separated by sliding gap ( 4 ), with a spring filter ( 15 ) equipped.

In the present case, the airway ( 11 ) free when the air opening ( 13 ) is available.

The spring filter ( 15 ) is with a distance rod ( 3 ) equipped with a pressure plate (outside) 1 ) and within the breathing opening ( 22 ) with a sealing plate ( 9 ) is integrally connected.

When exercising the finger pressure ( 17 ) on the printing plate ( 1 ) the spring filter ( 15 ) separated from the filter ( 16 ) with the sealing plate ( 9 ) to the sealing edge ( 12 ).

The air opening ( 13 ) is at zero. The airway ( 11 ) is blocked. The patient is no longer breathing through the breathing opening ( 22 ) and can thus initiate a speech process.

When the finger pressure decreases ( 17 ) the air opening ( 13 ), the patient can pass through the breathing opening ( 22 ) breathe and the breath gets through the filters ( 16 ) 15 ) moistened.

The 3 shows the peculiarities of the invention, in which all the functions and parts described as in 1 and 2 are present and act, but the adhesive layer ( 6 ) on a locking plate ( 21 ) is mounted for attachment of the heat-moisture exchanger, by a bead ( 19 ) into the tracheostoma patches ( 20 ) can be pressed.

The application of a sealing core ( 24 ) is in the 4 shown. All functions and items remain as in the 1 to 3 described, received.

The peculiarity in the 4 consists in the application of a sealing core ( 24 ) in a spring bush ( 23 ), which consists of air-permeable foam, is placed.

The spring bushing ( 23 ) has a heel ring ( 27 ) made of air-permeable foam, on which at the distance of the air opening ( 13 ) the sealing core ( 24 ) lies. The sealing core ( 24 ) is replaced by a flexible holding foil ( 25 ) on the skin ( 5 ) by means of connection ( 26 ) connected.

When exposed to finger pressure ( 17 ) the sealing core ( 24 ) through the sliding gap ( 4 ) so far down that he with the sealing edge ( 12 ) Has contact. This makes a speech possible because the airway ( 11 ) is blocked. Will the finger pressure ( 17 ), the air opening ( 13 ), so the airway ( 11 ) and the patient can breathe.

The holding foil ( 25 ) is also above the sliding gap ( 4 ), so that an additional spring force when pressing down the sealing core ( 24 ) and the spring socket ( 23 ) arises when the finger pressure ( 17 ) no longer works.

It is of course within the scope of the invention to use proposed heat-moisture exchange body with both sides attached airtight flexible elastic surface laminations on tracheostomy tubes, tubes, etc. with appropriate plan receiving surfaces, so that no separate heat-moisture exchanger must be kept for these uses.

All recognizable in the description, the embodiments and the following drawings features may be essential to the invention both individually and in any combination.
