Multi-channel oropharyngeal breathing device used in the anesthesiology department

Abstract

The invention relates to the technical field of medical instruments, in particular to a multi-channel oropharyngeal breathing device used in the anesthesiology department. The multi-channel oropharyngeal breathing device comprises an upper gingival fixation plate, a lower gingival fixation plate, a top plate, a tongue depressor, an air bag, a catheter, a porous breather pipe, an injection syringeand an intake pipe. The rear portions and the front portions of the upper gingival fixation plate and the lower gingival fixation plate are connected respectively by a first bending spring and a second bending spring, the inner wall of the front portion of the lower gingival fixation plate is tenon-connected with the top plate, and the top plate is connected with the tongue depressor located underthe top plate through the air bag; the structure of the upper gingival fixation plate and the structure of the lower gingival fixation plate are consistent with the gingival structure of the human body and cooperate with the first bending spring and the second bending spring in use to effectively fix the gingiva of a patient; the gingiva of the patient can be well fixed by using the top plate, the air bag and the tongue depressor in a cooperative way; the fixation degree of the tongue can be effectively adjusted by using the air bag to ensure the comfort of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-channel oropharyngeal ventilator for anesthesiology. Background technique [0002] The pharynx is a part of the neck. It is a conical passage connecting the oral cavity and nasal cavity to the esophagus and trachea (the junction of the esophagus and the trachea). It is located in front of the 1st to 6th cervical vertebrae. The lower border or level of the cricoid cartilage continues with the esophagus. The pharynx has an anterior wall, a posterior wall, and a side wall. The anterior wall is incomplete, so the pharynx communicates with the nasal cavity, oral cavity, and laryngeal cavity forward. The pharyngeal cavity is divided into three parts: the nasopharynx, oropharynx, and hypopharynx. The pharynx has functions of swallowing, breathing, protection and defense, and resonance. In addition, the pharynx is also an important pronunciation resonator, which plays ...

AI Technical Summary

Problems solved by technology

But most of the tongue depressors it adopts are close to the tongue, and the air permeability is poor, which makes the patient feel very uncomfortable.

In addition, the existing pharyngeal ventilation device cannot effectively suck out the sputum in the patient's body, and cannot alleviate the patient's discomfort.
