TECHNICAL FIELD
[0001] The utility model relates to the technical field of inspection device, concretely to a CT inspection lower limbs auxiliary fixed pillow. BACKGROUND
[0002] During CT examination, the fixation of the patient's legs is a key step, which ensures the accuracy of the scan and the safety of the patient. Double lower limb CT examination is more extensive, for example, patients with lower limb arteriosclerosis occlusion, lower limb arterial thrombosis, diabetic foot, lower limb trauma, lower limb venous thrombosis, lower limb varicose veins and the like need to perform lower limb arterial and venous or venous examination.
[0003] I. Inspection specificity
[0004] 1. The scanning range of double lower limbs is from the anterior superior iliac spine to the tip of the foot, the scanning range is relatively long, and the examination time is also relatively long. Usually, the scanning time of double lower limb CTA lasts for 40 to 60 seconds. Most patients cannot maintain stillness due to pain, and most of them will have slight movement of the tip of the foot or the knee joint, which will cause obvious motion artifacts and lead to examination failure. 2. Because the scanning range of double lower limb CTA is relatively long, the radiation dose is usually large. If the examination fails due to motion artifacts, it is necessary to re-inject contrast agent, and the amount of contrast agent injection is usually large, which is easy to increase the occurrence of drug adverse reactions; in addition, the scanning radiation dose is relatively large, so if the secondary scanning will cause certain harm to the patient. Therefore, appropriate tools should be used to try to ensure that the patient can be examined successfully once.
[0005] At present, the methods for fixing the legs during CT examination mainly include the following:
[0006] I. Traditional fixing method
[0007] Use bandage or gauze: for patients without leg fracture or serious injury, the doctor may use bandage or gauze to gently fix the leg to prevent movement during scanning.
[0008] Use brace or splint: for patients with slight leg fracture or requiring additional support, the doctor may use a brace or splint to fix the leg to ensure the accuracy of the scan; but usually it will produce artifacts, affecting the image quality. The existing fixing belt cannot completely match the patient's leg due to the thinness of some patients, so it cannot really fix the patient's leg; and the fixing efficiency is low, the operation is troublesome, time-consuming and laborious.
[0009] For some special patients, such as children, the elderly or patients with special diseases (such as osteoporosis, arthritis, etc.), before fixing the leg, the patient's leg condition needs to be fully assessed, including muscle tension, etc., for example, in winter, when the patient needs to do CT, the clothes on the legs need to be lifted, which causes the legs to be exposed, and the low temperature easily causes the patient's skin to be frozen and other problems. The shortcoming of the traditional fixing method is usually to use the fixing band of the gantry, but because the band is relatively short and has a relatively large gap in the middle, it cannot effectively fix the complete legs. And the lower limb venous examination often needs to be pressed, and the superficial veins are pressed to display the deep veins, which is currently realized by using a pressure bandage. However, the current pressure bandage has a small stress surface and poor compression effect.
[0010] Therefore, in view of this problem, a CT examination lower limb auxiliary fixing pillow is needed. Practical new type content
