FIELD: medical engineering. ^ SUBSTANCE: device has curved tube, cover, shield, metal cylinder, flexible plate and curved wire. Flexible curved tube is attached to one shield side and ring-shaped bead pressed with the cover is on the other side. One end of metal cylinder is beveled at an angle of 45° and the other one has thin rim. The flexible plate is shaped as the beveled cylinder base. The curved wire is attached to the plate with one end. The flexible tube has oval opening in the maximum curvature region, which area is equal to trachea cross-section area. Metal cylinder is enclosed in the flexible tube and rests with its rim upon the ring-shaped bead of the shield. The plate is mounted on the beveled base and attached to external surface of the cylinder with the other wire end. ^ EFFECT: enhanced effectiveness in creating voice; wide range of functional features; accelerated rehabilitation period. ^ 1 dwg |
