Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a CT artifact suppression neck brace. Background Technology
[0002] CT scans are a commonly used clinical examination method for preoperative and postoperative follow-up of thyroid cancer. Using CT scans for preoperative and postoperative examinations of thyroid diseases can provide preoperative and postoperative assessments and determine the presence of cervical lymph node enlargement (especially central lymph nodes) and metastasis.
[0003] To obtain good images of the thyroid gland during a CT scan, the patient should lie supine with their body on the bed. However, the thyroid gland is located in the neck and often overlaps with shoulder structures, making its anatomical structure quite unique. In a routine CT scan, part of the thyroid gland lies at the shoulder level, where both shoulder joints, both clavicles, and the soft tissue of the thyroid gland are on the same horizontal plane. Due to the uneven body thickness and abundant bone, X-rays attenuate significantly when passing through this plane, resulting in insufficient radiation reaching the detector. This creates beam artifacts on the thyroid CT image, reducing the surface area ratio (SNR) and affecting image quality.
[0004] In practice, directly increasing the radiation dose to eliminate hardening artifacts is generally not recommended. To address this challenge, some external devices have emerged to assist imaging. For example, the technical solution with application number 202110314909.4 discloses a medical imaging scanning auxiliary neck pillow. Specifically, during a medical imaging scan, the patient lies supine on the bed, and the auxiliary neck pillow is placed behind the patient's neck. Adjusting the width knob provides a more comfortable support width. Then, an elastic strap is placed over the patient's head to prevent head movement and thus maintain image quality. Finally, adjusting the height knob raises the second support plate, elevating the patient's neck and fully exposing the area to be scanned, resulting in a clearer image. However, this solution ultimately only fully exposes the patient's neck; its artifact elimination effect is not ideal, and its overall structure is extremely complex, making it inconvenient for practical operation and use.
[0005] Furthermore, the inventors discovered through research that the encapsulated saline solution placed in the neck has a good suppressive effect on CT artifact interference. Therefore, based on the above-mentioned problems, it is necessary to design a device that can suppress artifacts through the properties of saline solution and has a simple structure and is easy to use. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a CT artifact suppression neck brace that can effectively solve the aforementioned problems.
[0007] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:
[0008] A CT artifact suppression neck brace is provided, comprising two saline bag bodies arranged opposite each other, and a connecting bag body located between the two saline bag bodies; both ends of the connecting bag body are respectively connected to the two saline bag bodies; the upper ends of the two saline bag bodies are provided with neck pads facing each other; the connecting bag body, the two saline bag bodies, and the two neck pads together form a receiving cavity for accommodating the patient's neck.
[0009] The CT artifact suppression neck brace of this invention has an inner cavity in which the neck pad communicates with the saline bag body.
[0010] The CT artifact suppression neck brace of this invention has two saline bag bodies with opposite sidewalls and the upper sidewall of the connecting bag body, all of which are concave arc-shaped surfaces.
[0011] The CT artifact suppression neck brace of this invention has a saline bag body that is elongated and arranged along the front-to-back direction.
[0012] The CT artifact suppression neck brace of this utility model has forward-extending extensions at both the upper and lower ends of the front end face of the saline bag body. The opposite sidewalls of the two extensions are concave arc-shaped, and the cavity between the two extensions forms a receiving groove to accommodate the patient's shoulder.
[0013] The CT artifact suppression neck brace of this invention has a saline bag with a front-to-back length greater than the front-to-back length of the neck pad, and the lower rear end of the opposite sidewalls of the two saline bag bodies are provided with a pillow pad to prevent the patient's head from tilting.
[0014] The CT artifact suppression neck brace of this invention has an upper surface of the pillow cushion that is inclined, and the two inclined surfaces are arranged in a V-shape along the left and right directions.
[0015] The CT artifact suppression neck brace of this invention has a water inlet on the side wall of one of the two saline bag bodies that is away from the other saline bag body.
[0016] The beneficial effects of this invention are as follows: When in use, the connecting bag body and the saline bag body are pre-filled with saline, and then the connecting bag body is placed under the neck of the lying patient. The two saline bags and the neck pad are then wrapped and fitted around the patient's neck, which enables high-quality display of the neck CT images. The saline inside the saline bag body can greatly reduce the presence of artifacts, and the effect is obvious, greatly reducing the interference of artifacts on the doctor's observation of CT images.

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] The preferred embodiment of this utility model includes a CT artifact suppression neck brace, such as... Figure 1-3 As shown, the device includes two saline bag bodies 10 arranged opposite each other, and a connecting bag body 20 located between the two saline bag bodies 10. The two ends of the connecting bag body 20 are directly connected to the two saline bag bodies 10. Each of the two saline bag bodies 10 has a neck pad 30 facing each other at its upper end for attaching to the upper part of the patient's neck. The connecting bag body 20, the two saline bag bodies 10, and the two neck pads 30 together form a receiving cavity 40 for accommodating the patient's neck. Specifically, the saline bag bodies 10, the connecting bag bodies 20, and the neck pads 30 are all made of soft rubber. The connection between the outer walls of the saline bag bodies 10, the connecting bag bodies 20, and the neck pads 30 is an arc-shaped transition section to improve the patient's comfort and ensure that the inner wall of the receiving cavity 40 can fit in close contact with the patient's neck skin.
[0027] In use, saline is injected into the connecting bag body 20 and the saline bag body 10 beforehand. Then, the connecting bag body 20 is placed under the neck of the lying patient, and the two saline bag bodies 10 and the neck pad 30 are wrapped and attached to the outer periphery of the patient's neck. This allows for high-quality display of the neck CT images. The saline inside the saline bag body 10 can greatly reduce the presence of artifacts, and the effect is obvious, greatly reducing the interference of artifacts on the doctor's observation of CT images.
[0028] In this embodiment, the neck pad 30 has an inner cavity that is directly connected to the saline bag body 10, so that the neck pad 30, the saline bag body 10 and the connecting bag body 20 together form a water bag with an internal cavity. Saline can be flushed into the internal cavity and the corresponding parts can be attached to the corresponding positions on the patient's neck and shoulders, which can further distinguish the neck CT images from the surrounding background and further improve the quality of the CT images.
[0029] In this embodiment, the opposite sidewalls of the two saline bag bodies 10 and the upper sidewall of the connecting bag body 20 are all concave arc-shaped surfaces, so that they can fit snugly against the patient's neck skin after being worn, reducing gaps and improving the patient's comfort.
[0030] In this embodiment, the saline bag body 10 is elongated and arranged along the front-to-back direction, so that the saline bag body 10 can better fit the left and right sides of the patient's neck and fit along the length of the neck.
[0031] In this embodiment, the front end face of the saline bag body 10 is provided with forward-extending extensions 50 at both the upper and lower ends. The opposite sidewalls of the two extensions 50 are concave arc-shaped. The cavity between the two extensions 50 forms a receiving groove 60 to accommodate the patient's shoulder, so that the outer sidewall of the saline bag body 10 can fit more closely with the transition section of the shoulder and neck, reducing gaps.
[0032] In this embodiment, the front-to-back length of the saline bag is greater than the front-to-back length of the neck pad 30. The lower rear end of the opposite sidewalls of the two saline bag bodies 10 are provided with a pillow pad 70 to prevent the patient's head from tilting. Furthermore, the upper surface of the pillow pad 70 is an inclined surface, and the two inclined surfaces are arranged in a V-shape along the left and right direction. Through the cooperation of the two inclined surfaces on the two pillow pads 70, the patient's head can be prevented from tilting to the left or right during the examination, which would cause the neck muscles to twist and lead to abnormal CT images.
[0033] In this embodiment, one of the two saline bag bodies 10 has a water inlet 80 on the side wall of the side opposite to the other saline bag body 10, so as to facilitate the injection or discharge of saline.
[0034] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
