[0027] See also Figure 1 The elastic band includes an upper jaw elastic band 3 and a lower jaw elastic band 2, and the width of the lower jaw elastic band is greater than that of the upper jaw elastic band. The lengths of the upper jaw elastic band and the lower jaw elastic band are both 500 mm, the width of the upper jaw elastic band is 15 mm, and the width of the lower jaw elastic band is 25 mm; due to the difference in the size of the patient's face, the elastic band also has another size: the lengths of the upper jaw elastic band and the lower jaw elastic band are both 500 mm, the width of the upper jaw elastic band is 10 mm, and the width of the lower jaw elastic band is 20 mm, which is convenient for patients with smaller faces to wear and increases their wearing comfort.
[0028] See also Figure 1 and Figure 2The upper and lower elastic bands 3 and 2 are both provided with a net bag 4 for placing gauze in the middle. The net bag 4 is used to place gauze pads, apply pressure bandages, stop bleeding, and increase the force of the elastic bands to adjust the pressure. It can also make the bone mucosal flap fit closely with the jaw surface to protect the wound edge. Its function is that if the gauze pad is contaminated or wetted by the patient during oral care, gargling, and eating, it can be removed at any time and replaced with a clean gauze pad.
[0029] See also Figure 1 A pair of ear holes 8 are opened on the upper side of the four-head band body 1, and the under-ear elastic band perforation 11 is located above the inner side of the ear hole 8. The ear hole 8 is 110 mm away from the side end, and 20 mm away from the upper end of the four-head band body 1.
