Technical Field

[0001] This utility model relates to the field of head photography technology, specifically a portable full-head photography auxiliary device. Background Technology

[0002] Alopecia areata (AA) is the second most common non-scarring hair loss in clinical practice. AA can severely impact a patient's quality of life and may induce psychological disorders such as anxiety and depression. In clinical and real-world studies, the severity of AA and the evaluation of treatment outcomes require the use of the Severity of Alopecia Tool (SALT), which involves photographing the entire head (top, left temporal region, right temporal region, and occipital region) to allow clinicians to assess the area and severity of hair loss. An auxiliary device is needed to stabilize the head during the photographic process.

[0003] When shooting the entire head, the position and angle of the camera need to be moved frequently to ensure that the head is fully displayed. However, when adjusting the position of the camera, it is usually not easy to control the distance and angle between the camera and the head, resulting in a lack of good comparability of photos taken at different time points in the evaluation.

[0004] To address the above technical issues, we designed a portable full-head photography assistance device. Utility Model Content

[0005] The purpose of this invention is to provide a portable full-head photography auxiliary device, which has the advantages of being able to perform full-head photography and being more portable. It solves the problems of not usually having the advantage of being able to perform full-head photography and the inconvenience of carrying the device, making it convenient for use in clinical practice.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable full-head photography auxiliary device, comprising a horizontal plate, an auxiliary plate, a first fixed frame, and a second fixed frame. The top of the horizontal plate is movably connected to a frame via an electric rotating shaft. Electric push rods are provided on both sides of the inner cavity of the frame.
