Abstract

The invention provides a device for measuring the protruding distance of the mandible, which comprises a rectangular parallelepiped hollow box body, two ends of the box body are opened, and one end of the box body is provided with a protruding block as an external fixer for the upper teeth, and the outer fixator for the upper teeth is connected with the box Solid connections between bodies. In addition, an internal fixation part for the upper teeth is provided, and a groove for inserting the upper incisors is formed between the external fixation part for the upper teeth and the inner fixation part for the upper teeth. It also includes a measuring ruler and a lower tooth internal fixation piece and a lower tooth external fixation piece at the head end of the measuring ruler. A groove for placing the lower incisors is formed between the lower tooth internal fixation piece and the lower tooth external fixation piece. Place the upper and lower incisors of the patient in the above grooves respectively, induce the patient's mandible to move backward, and drive the measuring ruler back until the mandible is in the maximum retracted position, and record the reading of the measuring ruler at this time; then ask the patient to protrude the mandible until it reaches the maximum forward position , and record the reading of the measuring ruler at this time again. The difference between the two readings is the distance from the mandibular maximum retreat position to the protruding position to the maximum protruding position, which is the maximum protruding distance of the mandible.

Description

technical field

[0001] The invention relates to a medical auxiliary device, in particular to a mandibular protruding distance measuring device which can be used in conjunction with a mandibular forward-moving oral appliance for treating snoring and mild to moderate sleep apnea syndrome. Background technique

[0002] Snoring is a very common sleep phenomenon. Medically, it can be divided into benign snoring, sleep apnea and hypoventilation syndrome according to its severity. Breath holding in sleep is recurrent apnea, which causes serious brain and blood shortage. Oxygen, form hypoxemia, lead to sleep structure disorder, and induce high blood pressure, cerebral heart disease, arrhythmia, myocardial infarction, angina pectoris, etc., and even the apnea at night exceeds 120 seconds, which can easily lead to sudden death.

[0003] Classified by the site of action, oral appliances for the treatment of snoring and mild sleep apnea syndrome are divided into tongue appliances, soft ...
