Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a mandibular support device for general intravenous anesthesia without intubation. Background Art

[0002] Jaw support, also known as mandibular lift, is a temporary measure and basic treatment method to buffer upper airway obstruction. It is usually used for patients who have not yet started intubation after general anesthesia induction. The patient's lower jaw needs to be lifted. It is a common medical device.

[0003] In the process of lifting the patient's mandible, the mandible width of each patient is different. The existing mandible lifting device cannot be adjusted according to the width of the patient's mandible. When the patient's mandible width is not consistent with the width of the lifter during use, it will affect the patient's comfort. For example, Chinese patent publication number CN210521340U discloses a mandibular support device for general anesthesia during intravenous anesthesia without intubation. The device lifts the patient's mandible through a mandibular support, but the device cannot adjust the position of the mandibular support according to the width of the patient's mandible, so that the adaptability of the device is not perfect enough. Utility Model Content

[0004] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a mandibular support device for intravenous general anesthesia without intubation, which solves the problem that the existing devices in the prior art cannot adjust the position of the mandibular support according to the width of the patient's mandible, making the adaptability of the device insufficient.
