Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a mandibular positioner. Background Art

[0002] In routine anesthesia clinics, emergency rooms, and intensive care unit work, clinicians often face jaw support, such as: 1. During the induction period of general anesthesia to preserve spontaneous breathing, when the respiratory depressant drugs take full effect, the patient's spontaneous breathing weakens and upper airway obstruction occurs. During this process, the anesthesiologist needs to support the patient's jaw. The anesthesiologist can complete the jaw support process by supporting the jaw with one hand or both hands. If the patient's head and face are too enlarged, the anesthesiologist needs another anesthesia nurse to perform bag-assisted ventilation while supporting the jaw with both hands, or the anesthesiologist needs to perform mechanical ventilation while supporting the jaw with both hands to ensure adequate oxygen supply and ventilation. 2. During the recovery period of anesthesia extubation, patients are prone to respiratory depression and upper airway obstruction due to the residual effects of anesthetics and muscle relaxants. The anesthesiologist needs to support the patient's jaw to ensure a clear upper airway. 3. In the emergency department and intensive care unit, patients who are mechanically ventilated with a ventilator are prone to partial respiratory depression, upper airway obstruction, restlessness and intubation intolerance, accidental extubation, etc. in the state of consciousness or confusion due to their condition, the use of sedatives and analgesics, residual muscle relaxants, etc., and may need to be re-intubated and assisted with jaw support ventilation after evaluation.

[0003] The prior art mainly uses a mandibular lifter to assist medical staff in solving the above problems. In the process of using a mandibular lifter to lift a patient, the patient's head is first placed on the pillow seat, and then the height and rotation angle of the lifter are adjusted so that the lifter can effectively lift the human mandible. However, the lifter is generally connected to the pillow seat. When the patient's head is placed on the pillow seat, the position of the patient's head may not correspond to the position of the lifter. In actual operation, the position of the patient's head needs to be adjusted, which results in the need to move the patient's position as a whole, causing inconvenience in adjustment. Utility Model Content

[0004] In order to enable the mandibular positioner to quickly adapt to the patient's head, the present application provides a mandibular positioner.
