Description

Technical Field

[0001] The present application relates to the technical field of upper limb auxiliary support devices, and more specifically, to an upper limb auxiliary support device for CT enhanced scanning. Background Art

[0002] CT enhanced scanning is used to examine the blood flow of the vascular system and body parts. In some cases, such as patients with difficulty in upper limb movement, during CT enhanced scanning, it may be necessary to limit the patient's upper limbs and detect vascular problems or other related conditions. In this case, an upper limb auxiliary support device can be used to help the patient maintain a proper posture and stability to ensure image quality and patient comfort. The existing public technology number CN213465057U proposes an upper limb auxiliary support device for CT examination. The device has a simple structure, is easy to use, does not affect the normal operation of the CT examination equipment, is simple to operate, does not increase the examination time due to the addition of the utility model, does not increase the burden on the patient, and improves the patient's comfort; and can also adjust the inclination angle of the support block according to different patients. However, when used, the upper limb auxiliary support device in the literature is not convenient for use for patients of different body shapes, is inconvenient to wear, has low comfort, and is difficult to limit the patient's upper limbs, so that the patient is prone to abnormal body movements during the CT imaging examination, affecting the scanning quality. In view of this, we propose an upper limb auxiliary support device for CT enhanced scanning. Utility Model Content
