## Abstract

A device for reducing snoring includes a ventilation tube having an air passageway therein and a first opening and a second opening at opposite ends of the air passageway, wherein a diameter of the first end is greater than that of the second opening, and a holding member connected to the ventilation tube at an end having the first opening. Put the device of the present invention in mouth may hold a normal shape of the upper respiratory tract while the user is sleeping and ventilate the air without obstruction while the user is breathing, so the user would not snore in sleep to improve the quality of sleep.

## Claims

### Claim 1

A device for reducing snoring, comprising:
a ventilation tube having an air passageway therein and a first opening and a second opening at opposite ends of the air passageway, wherein a diameter of the first opening is greater than that of the second opening; and
a holding member extending from a wall of the first opening of the ventilation tube;
wherein the first opening and the second opening are adapted to be positioned in an oral cavity of a user;
wherein the ventilation tube and the holding member are made of silicon rubber and are integral;
wherein the ventilation tube has a bulged portion, which is adapted to move a soft palate of the user upwards wherein the ventilation tube is provided with two recesses recessed into a peripheral edge of the first opening towards the second opening, and the ventilation tube forms two flexible pieces on a lateral side of each of the recesses.

### Claim 2 (depends on 1)
