Description

Technical Field

[0001] The present application relates to the field of children's X-ray examination, and in particular to a children's X-ray radiological examination method and an examination chair. Background Art

[0002] During the X-ray examination of children, it is difficult for doctors to communicate with children or their guardians to understand the position and make the correct position according to clinical requirements. At present, people often use the guardian to hold the child for examination. This method often interferes with the results of the examination due to the guardian's own habits and concerns about the child's health, and will cause the guardian to be exposed to unnecessary ionizing radiation. At the same time, the holding method still cannot meet the clinical needs for clinical examinations such as the lateral and oblique positions of the airway and body. At the same time, the long examination time or inability to examine due to the positioning is also a major problem for pediatricians. On the other hand, the behavior of children is mostly not controlled by medical staff or guardians. Even after being comforted and fixed by the guardian, the nervous child will still struggle without warning. This situation will not only seriously affect the progress of the examination, but also the child and his guardian may be injured during the struggle.

[0003] In addition, there are three major technical pain points in current pediatric radiology examinations: (1) Traditional fixation devices lack size adaptability and cannot meet the body shape differences of children of different ages; (2) Inadequate protective measures and insufficient radiation protection for critical organs; (3) Repeated exposure problems caused by poor compliance of children during the examination.

[0004] In view of this, the inventor has developed a method and an examination chair suitable for children through intensive research. Summary of the invention

[0005] The purpose of the present invention is to provide a child X-ray radiation examination method and examination chair to solve the safety problems caused by the traditional detection method, such as guardians being exposed to unnecessary ionizing radiation, children's struggles without signs, and problems affecting the quality and efficiency of the examination.
