Description

Technical Field

[0001] The utility model relates to the technical field of oral cavity, in particular to an auxiliary chair for oral radiographic examination. Background Art

[0002] With the rapid development of stomatology, people pay more attention to oral health. More and more patients go to dental hospitals (departments) for treatment, and the proportion of children in the medical population is also increasing. With the increase in the number of children seeking medical treatment, the need for oral radiography also increases. Due to the particularity of radiography, each examination and even the examination of each part has its specific position. Commonly used oral radiography examinations include: periapical examination, panoramic examination, head positioning measurement (anteroposterior and lateral) examination and CBCT examination.

[0003] At present, panoramic film examinations and head positioning measurement (anteroposterior and lateral) film examinations in oral radiography examinations are mostly performed in a standing position. Some CBCT examinations also use standing position examinations depending on the machine model. When children are undergoing panoramic film examinations, head positioning measurement (anteroposterior and lateral) film examinations, and standing CBCT examinations, their bodies are prone to shaking in a standing position, resulting in motion artifacts and affecting the quality of the examination. When they are standing, they are wearing X-ray protective clothing. Because X-ray protective clothing is heavy, the frequency of body shaking increases, and the probability of motion artifacts is greater; when they are standing, the protective clothing is easy to fall off, and the protective effect is greatly reduced. The highest and lowest points of the machine racks for panoramic film examinations, head positioning measurement (anteroposterior and lateral) film examinations, and standing CBCT examinations have height and low limits. Children who are not tall enough to reach the lowest point of the rack need to stand on a low stool or chair to complete the examination during the filming process, which increases the probability of their body shaking and the probability of their falling, and at the same time increases the difficulty of the work of the inspection technicians.
