Description

Technical Field

[0001] This utility model relates to the field of mandibular support technology, and more specifically, to a mandibular support bracket. Background Technology

[0002] When a patient undergoes general anesthesia, they are unconscious. The muscles inside the patient's mouth relax, the patient's jaw opens, and the tongue falls back, which can cause airway obstruction, leading to difficulty breathing or even suffocation and death.

[0003] The existing patent with patent number CN 210228593 U discloses a chin support for anesthesiology. It uses a limiting plate to fit the patient's shoulder and support the travel sleeve. The spring uses its elasticity to fit the support plate to the patient's chin, thus achieving the purpose of supporting the patient's chin. However, the adjustment of the shoulder is inconvenient and it is easy to cause asymmetry in the length of the two sides. Moreover, the chin support plate is supported by a spring, and the force applied is different for patients with different neck lengths. Too much force will cause neck discomfort, and too little force will not achieve the desired effect.

[0004] In view of this, we have studied and improved upon the existing problems to provide a mandibular support, aiming to solve the problems and improve its practical value through this technology. Utility Model Content
