Embodiment Construction

[0035] figure 1 and figure 2 An example of an embodiment of a tracheostomy valve 1 according to the invention is shown. The tracheostomy valve 1 shown comprises a cap 2 , a filter means 3 , a cap seat 4 and an attachment means 5 . Note that for simplicity, Filter Tool 3 is not in the image 3 and Figure 4 shown in .

[0036] The lid 2 comprises elastic main walls having a general shape more or less similar to the shape of a dome. The elastic main wall comprises wall sections 22, 24, 25, wherein the wall section 25 has a circumferential connecting flange 26 connecting the cover 2 to the cover base 4 (see image 3 and Figure 4 ). In the wall part 25 there are a number of breathing openings 21 . In the illustrated embodiment, some of the breathing openings 21 are circumferentially spaced relative to each other. The shown filter means 3 , for example of foam material, is substantially ring-shaped and in operation the filter means 3 is placed coaxially in the dome-shap...

Abstract

A tracheostoma valve (1) comprises a main air passage structure (21, 41, 42) provided with a main valve arrangement. The tracheostoma valve is switchable in response to a spurt of inhalation air from a breathing condition into a speaking condition, while the tracheostoma valve is switchable in response to a spurt of exhalation air from said speaking condition into said breathing condition. The main valve arrangement comprises an at least partly flexible bistable wall portion (22, 23, 24) which has a circumferential bordering edge (23). At least part of the bordering edge forms a hinging means around which the bistable wall portion is hingeable between a first stable position in which an orifice (41) of the main air passage structure is being blocked, and a second stable position in which said orifice is released.

Description

technical field [0001] The present invention relates to a tracheostomy valve comprising a main airway structure provided with a main valve arrangement. Background technique [0002] Severe cancers in the laryngeal or hypopharyngeal region often require total laryngectomy, the removal of the larynx, including the vocal cords. Reconstruction is performed by directing the trachea externally. The trachea then ends at an opening in the neck, a so-called "tracheostomy". Following this procedure, voice restoration is usually performed by tracheoesophageal puncture and insertion of a one-way valve ("bypass valve") at the puncture site. In other words, such a bypass valve is inserted in the wall between the trachea and the esophagus. By closing the tracheostomy (manually or with the help of a so-called "tracheostomy valve"), at the top of the esophagus, exhaled air flows through a bypass valve to an air chamber surrounded by soft tissue, which then vibrates and acts as New "sound...
