Abstract
This utility model discloses an adjustable oropharyngeal tube, including a cover body, which is arc-shaped and has an installation through hole. A fixing tube is fixedly connected inside the cover body, and a guide tube is detachably connected inside the fixing tube. A spreading component is fitted on the guide tube, which includes a fixing ring, a connecting rod, and a spreading block. The fixing ring is rotatably fitted onto the guide tube, and the spreading block is fixedly fitted onto the guide tube. The front and rear ends of the connecting rod are respectively rotatably connected to a fixing rod one and a fixing rod two. The front end of the fixing rod one is installed on the rear side of the fixing ring, and the rear end of the fixing rod two is fixedly connected to the inner wall of the spreading block. According to the degree of opening of the patient's mouth, the opening size of the spreading block can be adjusted to open the patient's mouth to a certain angle, so that the guide tube can be smoothly inserted into the patient's mouth. Moreover, the spreading block can also play a certain protective role for the guide tube to prevent the patient from biting the guide tube, thereby ensuring the normal operation of the suction tube.
