Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a CT examination auxiliary device. Background Art

[0002] With the continuous development of CT technology, CT technology has now been widely used in clinical examinations, featuring fast scanning time and clear images. CT technology uses X-ray beams, gamma rays, ultrasonic waves, etc., and together with highly sensitive detectors, makes sectional scans around a certain part of the human body. CT technology has become the preferred examination for clinicians to diagnose many diseases.

[0003] Currently, during CT examinations, patients need to lie on the examination bed for the examination. Adult patients generally cooperate with the examination, but the examination bed is difficult to adapt to all body types of patients. For children who are naturally fidgety, due to their own restlessness, it is easy to cause inaccurate imaging of CT images, and a guardian needs to be present to watch. However, due to the certain radiation during CT examinations, even if wearing protective clothing, it may still cause certain radiation effects on the guardian, and it cannot guarantee that children will not move during scanning, thus requiring multiple repeated CT scans, resulting in low work efficiency. During the CT examination process, the rays will also irradiate other normal body parts that are not being examined, causing secondary harm to the patient, so it is necessary to cover and protect other non-examined body parts.
