Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a carotid artery volume imaging isolation pad auxiliary bracket. Background Art

[0002] As a disposable or reusable item that can be cleaned and disinfected, the isolation pad can reduce direct contact between the patient and the examination equipment during carotid artery volume imaging, thereby reducing the risk of cross infection.

[0003] Accurate imaging of the carotid artery requires ensuring the optimal relative position between the blood vessels and the ultrasound probe. An inappropriate neck angle may cause artifacts in the ultrasound image, which may interfere with the doctor's accurate judgment of the carotid artery structure. The traditional method is for nurses to instruct patients to maintain a specified angle and posture to complete accurate imaging of the carotid artery. However, when the patient always maintains the specified angle during this process, muscle fatigue will occur, making it impossible for the patient to maintain it stably, thereby reducing the image quality of carotid artery volume imaging.

[0016] (3) Beneficial effects

[0017] Compared with the existing technology, the present invention provides a carotid artery volume imaging isolation pad auxiliary stent with the following beneficial effects:

[0018] 1. This carotid artery volumetric imaging isolation pad auxiliary bracket manually rotates the handle during use, which can drive the movable headrest to move upward through a series of operations of the transmission mechanism, thereby effectively adjusting the patient's neck angle, allowing the volumetric imaging device to better display the blood flow in the carotid artery. The appropriate angle can also align the blood flow direction with the ultrasound beam direction, thereby more accurately assessing the blood flow velocity, direction, and presence of abnormal blood flow. This avoids artifacts in the ultrasound image caused by an inappropriate neck angle, which interferes with the doctor's accurate judgment of the carotid artery structure. It also avoids muscle fatigue caused by the patient maintaining a specified angle for a long time, thereby improving the image quality of carotid artery volumetric imaging to a certain extent.

[0019] 2. The carotid artery volume imaging isolation pad auxiliary bracket has an arc-shaped slide rail whose center is located on one side of the neck support seat, which can roughly coincide with the rotation point of the patient's cervical spine at the shoulder, so that the movement of the movable headrest can be more ergonomic, and the patient's discomfort can be reduced during the angle adjustment process, which can avoid the aggravation of the patient's injury to a certain extent.

[0020] 3. The carotid artery volume imaging isolation pad auxiliary bracket can be self-locking when adjusting the angle through the coordinated use of multiple sets of worm gears and worms. It can maintain the current position while also having a deceleration function, so that even nursing staff with less strength can perform the angle adjustment operation.
