Description

Medical bite-block

Technical Field

The utility model relates to the field of medical auxiliary equipment, especially, relate to a medical bite-block.

Background

The painless gastroscope is based on the ordinary gastroscope, firstly a certain dose of short-acting anesthetic is given through the vein to help the patient to quickly enter a calm and sleep state, the gastroscope is completed in no feeling, and the patient can quickly recover after the examination is completed. Because the patient has no pain in the painless gastroscopy process, the mechanical damage caused by the patient not conscious of restlessness under the painful state can be avoided, and the comfort level of the patient is further increased, therefore, the painless gastroscopy becomes the first-choice examination mode of more and more patients and doctors, but in the clinical painless gastroscopy, in order to prevent the tongue of the patient from blocking the oropharynx after anesthesia, the lower jaw of the patient can be lifted by another assistant doctor to achieve the aim of smooth ventilation, but still some patients have the problems of tongue blockage and small tongue blockage breathing because of the diseases of mandibular deformity, over-obesity, apnea syndrome and the like, the problems can not be solved by lifting the lower jaw, and at the moment, an anaesthetist is required to timely establish an artificial airway for the patient, such as the oropharynx airway, nasopharynx airway, laryngeal mask, tracheal cannula and the like, but a plurality of the modes still have problems, such as the oropharynx airway is too bulky, and if the operation space is used, the gastroscopy can not be realized; for example, the nasopharyngeal airway is too soft to support blocked soft tissues, so that the problem cannot be solved, and if the nasopharyngeal airway is made of hard materials, the nasal mucosa is easy to be damaged to cause bleeding; if the laryngeal mask is used, the esophageal opening is blocked, so that gastroscopy cannot be realized; if a trachea cannula is used, a lot of medicines with the effects of sedation, analgesia, muscle relaxation and the like need to be used, so that the medical expense of a patient is greatly increased, and meanwhile, the awakening time of the patient can be seriously prolonged by adopting the mode, and the characteristics of short gastroscopy time, high frequency and quick awakening can not be adapted.
