Description

Technical Field

[0001] The utility model relates to the technical field of head support, in particular to an auxiliary head support device. Background Art

[0002] In radiological diagnosis, contrast imaging is the process of taking in substances containing elements with high atomic numbers and then taking radiographs of the predicted internal parts for medical diagnosis. For structures or organs that lack natural contrast, substances with higher or lower density than the structure or organ can be introduced into the organ or the space around it to produce contrast imaging.

[0003] When performing cerebral angiography on a patient, the patient needs to lie flat on the angiography bed, but the patient is only supported on an ordinary headrest without a corresponding head fixation device. Since the patient's head is not fixed, the patient is prone to fatigue and head movement during the long-term angiography process, which will cause the angiography instrument to produce blurred or invalid images and affect the examination results. For this reason, the present application document provides an auxiliary head support device. Utility Model Content
