Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an auxiliary bracket for adjusting the body position of CT scanning patients. Background Art

[0002] Whole-body CT scanning refers to the use of CT (Computed Tomography) technology to scan and examine various tissues, organs, and parts of a patient's whole body. This examination method is widely used in clinical medicine for a preliminary judgment of most tissues and diseases in the whole body.

[0003] During the existing CT scanning process, due to some special patients losing the ability to control their bodies, limb movement will occur during the scanning process, and the limbs of such patients cannot be fixed. As a result, the CT scan images are blurred due to the patient's movement, leading to inaccurate scanning results and causing problems in scanning such patients. At the same time, the current scanner cannot appropriately raise the patient's legs according to the patient's body position during the scanning process to make the lumbar spine as parallel to the examination bed as possible, resulting in image distortion due to the physiological curvature during the scanning process and affecting the scanning effect.

Then the patient lies on the headrest fixing block 62 and starts to press the fourth fixing column 65, so that the fourth fixing column 65 is inserted into the fourth fixing groove 67 to fix the regulating plate 61. Then, the air blower supplies air to the intake hose 64. The intake hose 64 inflates the fixing airbag 63. Then the fixing airbag 63 flexibly fixes the patient's head, thereby realizing the flexible fixation of the heads of patients in different positions.

[0051] Working principle: When in use, according to the body position size of the patient, adjust the position of the arm fixing plate 7 in the mounting frame 1 to make it adjusted to a suitable position. At the same time, adjust the position of the strap fixing mechanism on the arm fixing plate 7 and the leg fixing plate 4.
