DE3733389A1 - Protective flap for laryngectomised patients - Google Patents

Abstract

The invention describes a protective flap for laryngectomised patients for protection of the trachea against irritating substances and contaminants and for facilitating supply of breathing air, which is characterised in that it comprises a multi-layer protective filter layer which has multi-filtering protective filter layers which meet the requirements and can be attached individually and easily detached, between the trachea and the protective flap.

Description

It is known that the larynx is directly through the trachea to breathe.

To protect the windpipe from irritants and pollutants, a protective bib is arranged, the z. B. from a good looking formwork and there is a slime absorbing gauze layer - directly on the air lying on the tube.

With this known arrangement the larynx has to go through the protective scarf and through the mucus-absorbing gauze layer breathe.

The protective scarf forms with its close contact naturally a breeding ground for germs.

Furthermore, the previously known protective scarf is not a filter against bacteria and / or acidic air pollutants, such as SO ₂ , HCl, HF, etc.

A lighter breathing air supply to the larynxes create and this breathing air of irritants and pollutants To keep free, it is proposed according to the invention, a Protective bib version for larynx lots according to the To use drawing.  

Fig. A and B are shown

with ( 1 ) the trachea,

with ( 2 ) a fastening collar, e.g. B. elastic or for binding or with Velcro;

with ( 3 ) the mucus-absorbing layer, which can preferably be made from skin-compatible gauze and, according to the invention, can preferably be impregnated with natural fragrances - breathable;

with ( 4 ) an A-carbon fleece or paper, which acts as an A-carbon filter, in order to remove preferably acidic air pollutants from the breathing air and of course also bacteria, etc .;

with ( 5 ) a chemisorption filter layer, also designed as a fleece layer or paper filter layer, for preferential separation of germs, bacteria, pollen, mold, spores and similar pollutants and irritants;

with ( 6 ) the actual scarf-shaped protective bib, which is provided with spacer beads ( 7 ) in the breathing area - placed above and below the trachea;

with ( 8 ) small flaps distributed over the filter surface, which allow the air to pass through the filter when inhaled, but not in the opposite direction, so that the moist exhaled air does not pass through the filter.

In this way it is achieved according to the invention that a lateral air opening ( 7 ) is created between the chemisorption filter layer ( 5 ) and the protective scarf ( 6 ), so that the breath is air without breathing resistance, which was previously provided by the protective bib or protective scarf the filter layers ( 4 ) and ( 5 ), which are matched to low resistance, can flow through in a manner that is breathable.

According to the invention, the beads ( 7 ) can of course also be arranged offset around the trachea, in order to allow the breathing air to flow in from all sides directly through the filter layers of the trachea without obstruction by the protective bib.

The individual protective layers, such as protective layer ( 3 ), ( 4 ) and ( 5 ), are connected to the protective bib ( 6 ) in an easily detachable manner, either by means of the collar and / or by a tie or Velcro fastener on the collar ( 2 ) attached. The same can of course be done with snap fasteners.

The spacer beads ( 7 ) can be attached directly to the scarf or can also be designed as a Velcro fastener.

Medications for respiratory healing or for Breathing relief in the filter fabric or in a bag in the Overall filter, preferably arranged in front of the gauze filter be.

Claims (6)

1. protective bib for larynxes, characterized in that it consists of a multi-layer protective filter layer between the trachea ( 1 ) and the protective bib ( 6 ) more subject-filtering, needs-based, individually accessible and easily removable protection - Has filter layers. 2. protective bib for larynxes, characterized in that the protective bib depending on the air pollution according to the air conditions can be seen with different protective filters ver, according to the invention first a skin-compatible mucus-absorbing gauze layer is applied to the skin around the trachea, this according to the invention is superimposed by an A-carbon filter layer ( 4 ) and this can in turn be overlaid with a chemisorption filter layer ( 5 ) as required, with appropriate air pollution, the distance of the chemisorption filter layer ( 5 ) to the protective scarf ( 6 ) by spacer beads ( 7 ) is carried out in order to feed the filtered breathing air preferably behind the protective bib ( 6 ) without passage impediment through the protective bib directly via the filter layers ( 5 ) and / or ( 4 ) and ( 3 ) of the trachea. 3. protective bib for larynxes, characterized in that the actual protective bib, which is designed as a good-looking scarf and is also breathable, is easily detachably connected to the other filter layers, preferably as a Velcro fastener, so that easy replacement of the protective filter layers protection bib ( 6 ) is given. 4. protective bib for larynx, characterized in that The smallest air in the direction of inhalation behind the filter flaps are attached, which is a sweep of the air allow in the direction of inhalation, but not vice versa. 5. protective bib for larynxes, characterized in that the filter layers are arranged one after the other on the skin:

• 1. Gauze filter
