Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an upper limb auxiliary fixation device for enhanced CT nursing. Background Art

[0002] Enhanced CT scanning is done by rapidly injecting contrast agent through a vein using a digitally controlled syringe, and then scanning again at the required time. Enhanced scanning utilizes the absorption difference between the diseased tissue and adjacent normal tissue to more clearly display the lesions. When performing a chest CT scan, both upper limbs need to be raised and fixed to both sides of the head to reduce interference from the arms.

[0003] The patent with the patent authorization announcement number CN213430168U discloses an arm fixing device for assisting CT enhanced scanning. The patent can support the arm and avoid the examiner's voluntary lifting action by designing the arm positioning block with an inclined structure along the arm extension direction. The lateral direction also has an inclined surface. After the arm is placed on the arm fixing table, the involuntary opening movement of the arm when extending can be avoided, solving the problems of difficulty in completing the lifting action and inability to straighten the arm. However, the patent still has some shortcomings in actual use. The angle of the arm positioning block is fixed and cannot be adjusted. Since the fixed angle is difficult to meet the patient's needs, the arm cannot be at a comfortable angle, resulting in load and soreness on the patient's arm during long CT scanning.

[0004] Therefore, there is an urgent need to provide an upper limb auxiliary fixation device with adjustable angle for enhanced CT nursing. Utility Model Content
