Abstract

Damp-heat exchange device for breathing air, characterized in that on a plaster (4) only a solid plate with an opening (16) or an outer cannula flange (3) or a housing (13) is materially connected and with an exchangeable, surface skin ( 10) provided filter (2) is equipped.

Description

The invention is a moist heat exchange device for placement on tracheostomy tubes or other tracheal tubes with and without universal approach.

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 attached to the universal cone of the tracheostomy tube or a tube and serve for pulmonary rehabilitation.

The moisture-heat exchangers remove moisture and heat from the exhaled air of the patient and return them to the patient via the inhaled air.

This filters the respiratory air, moisturizes it and prevents particles from entering the respiratory tract of the patient.

There are known a number of devices that act as a wet-heat exchanger and as a filter for particles.

In the PCT WO 95/17138 a tracheostomy filter with a spring valve is described. The application with a universal cone is not possible.

in the U.S. Patent 5,738,095 a same device will be described.

The U.S. Patent 5,259,378 offers a filter that is also incompatible with the universal cone of a tracheostomy tube.

The U.S. Patent 4,971,054 offers a filter that can be connected to a universal cone, but redirects air flow based on shower protection.

In the PCT WO 98/33543 a filter with adhesive film is described.

Another utility model has a filter with a surface seal against air and an adhesive ring for mounting on the flange of an inner cannula.

In general, it has been found that the known humid-heat exchange solutions for respiratory air in tracheal cannula users are deficient in connection with the universal cone, with respect to air flow guidance and large construction.

Accordingly, the invention has for its object to provide a moist heat exchange device for uncomplicated connection with a low overall height, lateral breathing flow, applicable for tracheal cannula plates and tracheostoma with safety cover, to achieve high comfort and optimal breathing control.

This object is achieved with a device which is designed as a wet-heat exchanger in a round, square or oval foam shape, the connection with a tracheostoma patches allows by surface lamination with an air-impermeable film the lateral respiratory flow guaranteed and also allows speech functions.

The connection is made by releasable adhesive bonds between HME and plaster.

• – Schaumstoffscheibe mit Oberflächenkaschierung als HME,
• – Pflaster mit Schutzfolie,
• – Klebescheibe
• – fester Platte.

The device according to the invention basically consists of the following components:

• - Foam disc with surface lamination as HME,
• - plaster with protective film,
• - Adhesive disc
• - solid plate.

The foam in round, square or oval shape is porous and the surface is coated with a film that allows no air or breath.

The solution is that an air-permeable, open-pore foam, which is covered with a film on the surface, does not allow air through, whereby the breath is laterally discharged and introduced through a round film opening in the flange area.

By means of finger pressure, the foam with the upper foil can be pressed onto the opening of the fixed plate, which diverts the breath and allows speech functions.

Breath losses between a filter housing and the filter are reduced to zero.

The wearing comfort and the breathing quality are improved.

The invention is explained in more detail by the attached figures: Of these show:

1 : a plaster with cannula flange

2 : a plaster with housing.

In the 1 The application of an HME (artificial nose) with a detachable connection of the foam filter ( 2 ) by a Innenkanülenflansch ( 1 ) with an outer cannula flange ( 3 ).

The inner cannula flange ( 1 ) is with a seal ( 12 ), which after the connection of both flanges, the escape of breathing air ( 11 ) outside the filter ( 2 ) prevented.

The patch ( 4 ) is connected to the flange of the outer cannula ( 3 ) connected cohesively.

After removing the protective foil ( 7 ) by means of handles ( 6 ), the plaster is applied via the open tracheostoma by means of an adhesive layer ( 8th ) glued.

The airway ( 11 ) passes through the tracheostoma, the tracheal cannula stump or tube ( 5 ), the outer cannula flange ( 3 ), the inner cannula flange ( 1 ), the breathing opening ( 16 ), through the filter ( 2 ).

The respective filter ( 2 ), with a surface skin ( 10 ), by means of adhesive ring ( 9 ) on the inner cannula flange ( 1 ) attached.

Replacing the filter ( 2 ) takes place by removing the Innenkanülenflansches ( 1 ) from the outer cannula flange ( 3 ).

By using the fixed Außenkanülenflansches ( 3 ) can be applied to the filter by finger pressure ( 2 ) the opening ( 16 ), allowing speech to be made.

In the 2 is the application of an HME of a filter ( 2 ) with a laterally open housing ( 13 ).

The filter ( 2 ) with surface skin ( 10 ) is placed in the housing ( 13 ) with the opening ( 16 ) In the direction of the tracheostoma.

After removing a protective film from the housing ( 13 ) the adhesive ring ( 14 ) on the pavement ( 4 ) glued.

The airway ( 11 ) takes place through the tracheostoma, the patch ( 4 ), through the opening ( 16 ) and laterally through the housing ( 13 ).

Replacing the filter ( 2 ) with the removal tab ( 15 ) carried out.
