[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0023] Example:

[0024] like Figures 1 to 4 As shown, the utility model provides an angiography support, including a headrest 11, on which a pillow cavity 12 is arranged, and the setting of the pillow cavity 12 provides a space for accommodating the patient's head. Two groups of first brackets 13 are arranged on both sides of the headrest 11, and the first bracket 13 is connected to the second bracket 14 through a connecting pin, and one end of the second bracket 14 is rotatably connected to a pressing block 15. Flexible rotation connection is achieved through the connecting pin, which facilitates adjustment of the angle and height between the first bracket 13 and the second bracket 14 and between the second bracket 14 and the pressing block 15 to adapt to the head shape and angiography requirements of different patients. The pressing block 15 contacts the head, and a sponge pad 27 is arranged on the pressing block 15. The pressing block 15 is in direct contact with the patient's head, which is enough to ensure the stability of the head during the examination. The sponge pad 27 improves the patient's comfort and reduces the discomfort caused by maintaining a fixed posture for a long time, and the sponge pad 27 can also fit the head for easy fixation.

[0025] A clamping sleeve 16 is provided on one side of the headrest 11; a fixing plate 17 is provided under the headrest 11, and an adjustment component is clamped on the fixing plate 17.
