AI Technical Summary
In current thyroid CT scans, artifacts are caused by the density difference between the soft tissue in the neck and the air around the neck, which affects the scanning results. In addition, the existing saline bags need to be attached to the patient's neck, which is cumbersome to operate.
A saline bag designed to prevent artifacts in thyroid CT scans is described. It adopts a horizontal strip structure with the horizontal section placed on the front of the neck and the left and right ends hanging down naturally to cover both sides of the neck. The bag has multiple fluid storage units and connecting holes inside to form a saline channel, simplifying the operation.
It can effectively block the front and sides of the neck without the need for binding, reducing artifacts, improving scanning accuracy, and simplifying the operation process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a saline bag for thyroid CT scan anti-spoofing. Background Technology
[0002] Thyroid CT scans use X-ray imaging technology to generate detailed cross-sectional images of the thyroid gland and surrounding structures, helping doctors assess the size, shape, location, and presence of nodules, enlargement, or other abnormalities. The patient lies supine on the CT scan table, and the CT scanner emits narrow beams of X-rays from multiple angles toward the patient's neck. These beams attenuate to varying degrees as they pass through materials of different densities. Due to the significant density difference between the soft tissues of the neck and the surrounding air, thyroid CT scans are prone to artifacts, affecting scan quality and accuracy. Therefore, during thyroid CT scans, it is usually necessary to use saline bags with a density close to that of the soft tissues of the neck on the front and left and right sides for cushioning. Each saline bag needs to be attached to the area being blocked, which is cumbersome. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a saline bag for thyroid CT scan anti-spoofing. This saline bag does not need to be tied. It can be placed on the front of the patient's neck to block the front of the neck and the left and right sides at the same time.
[0004] To solve the above problems, the present invention provides a thyroid CT scan anti-counterfeiting saline bag, which includes a horizontally elongated strip-shaped crossbar, the middle of which blocks the front of the neck while the left and right ends hang down to block the left and right sides of the neck.
[0005] Furthermore, the interior of the crossbar is filled with salt water.
[0006] Furthermore, a vertical section extends downwards from the horizontal section for laying on the chest.
[0007] Furthermore, both the transverse and longitudinal sections are divided into multiple independent liquid storage units.
[0008] Furthermore, each storage unit is filled with brine.
[0009] Furthermore, the crossbar is equipped with an inlet and an outlet.
[0010] Furthermore, the saline bag is divided into multiple liquid storage units. There are connecting holes between adjacent liquid storage units to form a saline channel. The saline channel is connected to the inlet at the beginning and to the outlet at the end.
[0011] Beneficial effects: The horizontal bar of the saline bag is a long, horizontal strip. When the patient lies supine on the CT scanning bed for a thyroid CT scan, the horizontal bar of the saline bag is placed horizontally, with the middle part of the horizontal bar draped over the front of the patient's neck to block the front of the neck, and the left and right ends of the horizontal bar naturally hanging down to the left and right sides of the patient's neck to block the left and right sides of the neck, without the need for binding.

[0017] 1-Horizontal baffle; 2-Liquid storage unit; 3-Inlet; 4-Outlet; 5-Brine channel; 6-Longitudinal section. Detailed Implementation
[0018] The present invention will be further described in detail below with reference to specific embodiments.
[0019] First implementation of anti-spoofing saline bags for thyroid CT scans, for example Figure 1 As shown, the bag includes a horizontally elongated strip-shaped transverse baffle 1, from which a vertical section 6 extends downwards, forming a T-shape for the entire saline bag. Both the transverse baffle 1 and the vertical section 6 are internally divided into multiple independent liquid storage units 2 (see...). Figure 2 Each reservoir unit 2 is filled with saline solution (not shown in the attached diagram). During a thyroid CT scan, the patient lies supine on the CT scan bed. The horizontal baffle 1 of the saline bag is placed horizontally, with its middle section draped over the front of the patient's neck to block the front of the neck. The left and right ends of the horizontal baffle 1, under the influence of gravity, naturally droop down to the left and right sides of the neck, thus forming a "∩" shape around the patient's neck. The saline solution in the horizontal baffle 1 effectively blocks the front and left / right sides of the patient's neck, reducing the likelihood of artifacts due to density differences during scanning and resulting in high accuracy. In this position, the vertical section 6 lies flat on the patient's chest, both to distribute pressure on the neck and to keep the center of gravity of the saline bag in front of the patient's chest, preventing displacement.
[0020] In the first embodiment, when the saline bag 1 is manufactured, its storage unit 2 is already full of saline, and there is no need to add saline during use. Second embodiment example Figure 3 As shown, the upper left side of the crossbar 1 has a water inlet 3, and the right side has a water outlet 4. (See...) Figure 4 The saline bag has a connecting hole (not shown in the figure) between two adjacent reservoir units 2 inside, forming a saline channel 5. The saline channel 5 is connected to the inlet 3 at one end and to the outlet 4 at the other end. When in use, the saline bag is placed vertically. Saline solution is poured into the bag from the inlet 3, flowing along the saline channel 5 until it overflows from the outlet 4. After a period of time to ensure the bag is full, the inlet 3 and outlet 4 are sealed, and the bag can then be placed around the patient's neck. After use, the saline solution is poured out through the outlet 4 and the bag is stored.
[0021] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
