technical field

The invention relates to a mouthpiece, in particular to a mouthpiece with double-layer materials.

Background technique

The mouthpiece is used in anesthesia or oxygen infusion patients to support the upper and lower teeth to prevent the patient from involuntarily biting the endotracheal tube during anesthesia or first aid, causing blockage of the endotracheal tube, affecting the patient's breathing and possibly causing suffocation. Therefore, it is necessary to use a mouthpiece made of hard material to prevent the patient from biting the endotracheal tube. However, when the patient has just withdrawn from anesthesia or just woke up, the foreign body in the mouth will feel uncomfortable and quite rejected, and it may also be caused by pain. Bite the mouthpiece hard, but the mouthpiece made of hard material may cause the patient's teeth to break. In order to solve such problems, such as the "Mouth Guard for Use with a Diagnostic Instrument" of U.S. Patent No. 4640273, it discloses a mouthpiece with a hard inner layer and a flexible soft material on the outer layer, so as to prevent the teeth from biting the hard material. And the problem of breaking occurs.

Infection of the inner lining of the oral cavity may lead to many unexpected major complications for severe patients, which in turn affects the patient. The recovery time is more likely to aggravate the patient's condition.

In addition, due to the different materials of the inner and outer layers, they are bonded and fixed to each other by means of a connecting agent. When the patient clenches the mouthpiece tightly, the flexible and soft outer layer of the mouthpiece is easily affected by external forces. Impact and fall off, resulting in the risk of use. Furthermore, the ring-shaped design close to the lip is also likely to cause many lip pressure sores due to long-term pressure on the patient's lip, which in turn leads to infection problems.

Contents of the invention
