Embodiment 1

[0022] refer to figure 1 , the mandibular protruding distance measuring device provided by the present invention comprises a rectangular parallelepiped hollow box body 1, the two ends of the box body 1 are open, and one end of the box body 1 is provided with a protruding block as the upper tooth external fixer 2, and the upper tooth is externally fixed Part 2 is fixedly connected with box body 1. In addition, an upper tooth internal fixation part 3 is provided, and a groove for inserting the upper incisors is formed between the upper tooth external fixation part 2 and the upper tooth internal fixation part 3 .

[0023] It also includes the measuring ruler 4 and the lower tooth internal fixation part 42 and the lower tooth external fixation part 41 at the head end of the measuring ruler, and the groove for inserting the lower incisors is formed between the lower tooth internal fixation part 42 and the lower tooth external fixation part 41. The other end of measuring ruler 4 is...

Embodiment 2

[0027] refer to figure 2 , on the basis of Embodiment 1, the lower surface of the box body 1 away from the lower tooth external fixation piece is open, and the inner wall of the upper surface is exposed, and the inner wall of the upper surface is provided with a length scale. Grit the back teeth lightly. The doctor observed the patient's anterior overbite coverage and the midline of the upper and lower dentition, and made records. The upper and lower incisors of the patient are respectively placed in the above-mentioned grooves. The doctor instructs the patient to relax the mandible as much as possible, and puts the hand on the chin to induce the patient to move the mandible backward and drive the measuring ruler 4 back until the mandible is in the maximum receded position. Record the scale D1 corresponding to the end of the measuring ruler, expressed as a negative number.

[0028] Then advise the patient to protrude the mandible until the maximum protruding position, fix t...

Embodiment 3

[0032] refer to image 3 and Figure 4 , in this embodiment, the inner walls of both sides of the box body 1 are provided with horizontal protruding strips 11, and grooves 12 are formed between the horizontal protruding strips 11. Both sides of the measuring ruler 4 are provided with chute 43 .

[0033] The protruding strip 11 is placed in the chute 43 , and both sides of the chute 43 are placed in the groove 12 , so the measuring ruler 4 can slide in the box body 1 .

[0034] In this embodiment, the number of raised strips 11 and grooves 12 can be multiple, such as image 3 shown. In this way, the vertical height of the lower measuring ruler can be set according to the patient's overlay, so that the mandible can flexibly protrude.

Abstract

The invention provides a lower-jaw protraction distance measuring device which comprises a cuboid-shaped hollow box with two open ends, a measuring ruler, an internal lower-teeth fixing piece and an external lower-teeth fixing piece. One end of the box is provided with a protruding block serving as an external upper-teeth fixing piece, and the external upper-teeth fixing piece is fixedly connected with the box. An internal upper-teeth fixing piece is further provided, and a groove for accommodating upper incisor teeth is formed between the internal upper-teeth fixing piece and the external upper-teeth fixing piece. The internal lower-teeth fixing piece and the external lower-teeth fixing piece are arranged at the head end of the measuring ruler. A groove for accommodating lower incisor teeth is formed between the internal lower-teeth fixing piece and the external lower-teeth fixing piece. The upper incisor teeth and the lower incisor teeth are disposed in the grooves respectively, the lower jaw of a patient is led to retract to drive the measuring ruler to retract until being at a maximum retraction position, and a reading of the measuring ruler at this moment is recorded; afterwards, the patient is asked to protract the lower jaw until the lower jaw reaches a maximum protraction position, and a reading of the measuring ruler at this moment is recorded again; the difference value of two readings refers to the distance from the maximum retraction position at the lower jaw to the maximum protraction position at the lower jaw, namely the maximum lower-jaw protraction distance.

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 ...
