Lower jaw bracket used for intravenous anesthesia without cannula

Abstract

The lower jaw bracket comprises two channel steel plates, four positioning bolts and a reinforcing rib, the two channel steel plates are oppositely arranged, the four positioning bolts are connected to the front ends and the rear ends of the upper surfaces of the two channel steel plates in a screwed mode respectively, the reinforcing rib is fixedly connected to the rear ends of the inner sides of the channel steel plates, and the reinforcing rib is fixedly connected to the inner sides of the channel steel plates. The supporting plate is fixedly connected to the middle of the upper surface of the channel steel plate located on the left side; the first rotating shaft is rotatably mounted on the right side of the supporting plate through a bearing; the supporting mechanism is fixedly connected to the right end of the first rotating shaft; the angle adjusting mechanism is installed in the middle of the upper surface of the channel steel plate located on the right side. The lower jaw of a patient can be lifted for a long time, and the head of the patient can be kept in a backward leaning state, so that the purpose of keeping the upper respiratory tract of the patient unobstructed during intravenous anesthesia without intubation in a short operation is achieved, the anesthesia safety of the patient is facilitated, and physical exhaustion and anesthesia working intensity of an anesthetist can be relieved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a jaw bracket for total intravenous anesthesia without intubation. Background technique [0002] During general anesthesia, endotracheal intubation is the strongest stimulus. Endotracheal intubation under light anesthesia can cause severe coughing, suffocation and even bronchospasm. Arrhythmia, ventricular fibrillation, etc., can be life-threatening in severe cases. At the same time, some patients are not suitable for general anesthesia using muscle relaxant drugs and endotracheal intubation, especially the following groups: ① patients with myasthenia gravis undergoing thymectomy; ② severe chronic obstructive pulmonary disease (chronic obstructive pulmonary disease, COPD) undergoing thymectomy Lung volume reduction surgery; ③allergic to muscle relaxants; ④pregnant women who need general anesthesia; ⑤tracheal tumor resection, carina reconstruction; ⑥casters, singers and other sp...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mandibular bracket for total intravenous anesthesia without intubation, to at least solve the problem that the existing technology cannot adjust the angle of the patient's head back and raise the mandibular angle of the patient, so as to solve the problem of the patient's total anesthesia without intubation. After intravenous anesthesia, the upper airway is not smooth due to the relaxation of the jaw and the tongue falling backward
