The occlusion groove is designed into an arc-shaped structure, is approximately the same as the sequential structure of tooth arrangement, and is convenient for occlusion of a patient.
The tying rope is a buckle tying rope, so that the neck of the patient can be fixed by the insertion tube more conveniently, and the comfort degree of the patient is improved.
The suction tube is provided with a sealing cover, and the sanitation of the suction tube can be ensured by covering the sealing cover.
When carrying out trachea cannula art, adjust the bite-block earlier to approximate position then insert patient's trachea with the intubate, whether insert back inspection intubate with patient's trachea laminating, if there is the gap, then aerify the intubate through the gas tube, make the intubate inflation, laminate with patient's trachea completely, prevent that the gas leakage condition from appearing, after the intubate finishes, adjust the bite-block once more, make interlock groove and patient's tooth agree with, improve patient's comfort level, wind the ligature rope to patient's neck after that, connect through the buckle, reach the purpose of fixed intubate once more, when there is the secretion in patient's oral cavity, can with its suction through attracting the pipe.
The adjustable dental pad has the advantages of simple structure and low manufacturing cost, the position of the dental pad can be adjusted according to the condition of a patient by adopting the matching of the adjustable dental pad and the intubation tube, the adjustment of medical staff is convenient, the teeth of the patient can be placed when the patient is occluded through the groove, the comfort level of the patient during intubation is improved, and the adjustable dental pad has the characteristics of convenience in operation, high comfort level and the like.
