Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for assisting lower limb vascular ultrasound examination. Background Technique

[0002] Lower limb vascular ultrasound examination refers to using an ultrasound beam to scan the human body, obtaining an image of the lower limb blood vessels by receiving and processing the reflected signals, and determining related lesions of the lower limb blood vessels based on the walking patterns of the lower limb arteries, deep and superficial veins, the thickness of the vascular intima, the size of the lumen, and the blood flow conditions. Lower limb vascular ultrasound examination can check whether there are sclerosis, plaques, stenosis or occlusion in the lower limb arteries, whether there are aneurysms or arteriovenous malformations, whether the veins have reflux or occlusion, and at the same time observe the normal conditions of the lower limb arteries and veins to clarify the location and size of the lower limb thrombus.

[0003] During ultrasound scanning, in order to facilitate the ultrasound probe to scan the lower limbs, it is necessary to position the patient's lower limbs. It is difficult for the patient to position themselves, especially for elderly patients and those with limited mobility. Therefore, additional medical staff are often needed to hold the patient's lower limbs to achieve abduction, leg raising, and knee bending of the patient's lower limbs. However, when the medical staff help the patient position the lower limbs, it is inconvenient to position, and it is easy to get tired when lifting the patient's lower limbs.
