Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a mandibular lifting device for anesthesiology. Background Art

[0002] During the induction of general anesthesia in the operating room, when the patient has respiratory depression or respiratory arrest, the anesthesiologist needs to hold up the patient's jaw with his hands and use an oxygen mask to supply oxygen under pressure. During general anesthesia without the need for muscle relaxants, the anesthetic drugs will have a certain respiratory depression effect on the patient, so the patient's jaw needs to be held up to ensure the patency of the airway to ensure adequate oxygen supply to the patient, regardless of whether the oxygen is supplied by mask or nasal cannula. However, holding up the jaw by hand for a long time is not only very strenuous, but also a waste of human resources. Especially when rescuing patients with respiratory and cardiac arrest, a medical staff member must hold up the patient's jaw for a long time to ensure the patency of the airway and supply oxygen.

[0003] A Chinese patent with application number CN202221950110.0 discloses a mandibular support for anesthesiology, including a fixed seat, a vertical bar, a first cross bar, a second cross bar and a support plate. The fixed seat is used to be fixed on the edge of the bed. The vertical bar is arranged on the back of the fixed side and can be moved vertically. The first cross bar is arranged at the upper end of the vertical bar and can be adjusted in the left and right directions. One end of the second cross bar is connected to the end of the first cross bar and is perpendicular to the first cross bar. An adjustment rod is inserted at the other end of the second cross bar, and the adjustment rod moves along the length direction of the second cross bar. The support plate is arranged at the end of the adjustment rod to support the patient's mandible. However, the device cannot adjust the angle of the support plate. In view of this, the inventor proposes a mandibular lifting device for anesthesiology. Utility Model Content
