Problems solved by technology

However, since Candida will still form adjacent to the valve member and on the valve seat and accumulate to some extent on the valve member, even if Candida does not grow into the anti-Candida material, regardless of the distance between the valve member and the valve seat. The valve member will not be able to fully close against the valve seat due to the magnetic attraction
Also, candida that forms on / near the valve seat may collect at the valve / seat along with mucus, food, etc., which can cause leakage until it is removed

Embodiment Construction

[0012] The following description relates to embodiments of the invention suitable for use in vocal prostheses, and also to methods for manufacturing such vocal prostheses.

[0013] The invention will be described in more detail below with reference to the accompanying drawings, in which, Figure 1 to Figure 3 are axial and perspective cross-sectional views of different embodiments of a vocal prosthesis 1000 according to the present invention.

[0014] In the basis of the present invention figure 1 In an embodiment of the present invention, a vocal prosthesis 1000 is disclosed. The vocal prosthesis 1000 includes a lateral tubular body 100 . The tubular body 200 has an axial distal end and an axial proximal end. During use, the proximal end will face the user's esophagus and the distal end will face the trachea. The proximal end is provided with an esophageal retention flange 101 . The distal end is provided with a tracheal retention flange 102 . The esophageal retention f...

Abstract

A voice prosthesis for mounting in a fistula between trachea and esophagus is provided. The voice prosthesis comprises a tubular body having a lumen, a valve disc and a valve seat. The valve disc and a valve seat are arranged in the lumen of the tubular body, such that the valve disc and the valve seat control the connection through the lumen by interaction between the valve disc and the valve seat. A sealing rim is arranged between the valve disc and the valve seat, such that the interaction between the valve disc and the valve seat is obtained via the rim. A method for manufacturing a voice prosthesis is also provided.

Description

technical field [0001] The present invention relates to a vocal prosthesis to be installed in a fistula between the trachea and the esophagus. More specifically, the present invention relates to a vocal prosthesis comprising a tubular body having a distal end and a proximal end, wherein retention flanges are arranged to extend laterally from the tubular body in a transverse plane, said flanges being respectively arranged at Proximally and distally, the vocal prosthesis also includes a valve member for closing communication through the tubular body but opening when subjected to air flow in a proximal direction. The invention also relates to a method for manufacturing such a vocal prosthesis. Background technique [0002] When a patient's larynx is surgically removed due to pathological changes in the throat, the patient's trachea is sutured to the opening in the throat. This is called a tracheostomy. As a result of the surgery, the patient lost the ability to speak, and in...
