Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel CT examination pillow with an arm support structure. Background Art

[0002] CT examination is a modern, fast, safe, and advanced medical examination technology with high tissue resolution, and is widely used in clinical practice. During all CT examinations of abdominal and chest organs, patients need to raise their hands as much as possible. The reasons are: first, to increase the intercostal space as much as possible and obtain a clearer image of the internal tissue of the chest; second, to reduce the limb artifacts caused by placing the arms on both sides of the body. Since most pillows now do not have arm supports, many elderly and weak patients find it difficult to raise their hands and cannot keep them for a long time. During the CT scan, they are prone to move and bend on their own, resulting in image artifacts, and even scratching and injuring the CT scanning bore wall. When the image artifacts are serious, the technician will rescan to obtain a better image, which will increase the patient's radiation dose and affect the patient's health. Therefore, a new CT examination pillow with an arm support structure is proposed to solve the above-mentioned problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, a new type of CT examination pillow with an arm support structure includes a heightening pad 1, a pillow body 2, a supporting component 3 and an arm support body 4.

[0022] It should be noted that CT examination is a relatively advanced modern medical scanning examination technology, which is mainly used to scan the human brain. During the examination, the patient needs to lie on the examination bed with his head placed on the pillow body 2, and the arm rest body 4 is used to support the patient's arm to prevent the arm from moving or bending.

[0023] The supporting assembly 3 includes two fixed cylinders 301, and fixed cylinders 301 are fixedly installed at the rear positions on both sides of the heightening pad 1, and adjusting rods 302 are movably installed inside the two fixed cylinders 301. Cavities 303 are opened inside the two fixed cylinders 301, and movable rods 304 are movably installed inside the two cavities 303. The outer surfaces of the two movable rods 304 are sleeved with extrusion springs 305, and movable plates 306 are fixedly installed on the outer surfaces of the two movable rods 304. Five slots 307 are opened inside the two adjusting rods 302, and connecting rods 308 are movably installed on the tops of the two adjusting rods 302.

[0024] Specifically, the height of the arm support body 4 can be adjusted by pulling the movable rod 304. The movable rod 304 is pulled out of the slot 307, and the adjustment rod 302 is moved. After the position of the adjustment rod 302 is determined, the movable rod 304 is released and the squeeze spring 305 is used to insert the movable rod 304 into the slot 307 to fix the adjustment rod 302. The height of the arm support body 4 can then be adjusted to meet the needs of different patients and improve the comfort of the patients.

[0025] The two adjusting rods 302 are both internally installed with a tilting assembly 5 .

[0026] The two tilting components 5 each include a movable groove 501, the interior of the two adjusting rods 302 is provided with a movable groove 501, the interior of the two movable grooves 501 is rotatably installed with a rotating rod 502, the inner bottom walls of the two movable grooves 501 are fixedly installed with two return springs 503, the tops of the two return springs 503 are fixedly installed with latch teeth 504, and the outer surfaces of the two rotating rods 502 are fixedly installed with two gears 505.

[0027] Specifically, when adjusting the tilt angle of the arm support body 4, the arm support body 4 is manually moved, and the movement of the arm support body 4 will drive the rotating rod 502 to rotate in the movable groove 501, and the two reset springs 503 are compressed by using the two latch teeth 504. When the tilt angle is determined, the movement of the arm support body 4 can be stopped, and the two gears 505 are limited by the two latch teeth 504, so that the arm support body 4 is easy to adjust the tilt angle, thereby achieving the purpose of retraction and adjustment.

[0028] Slide grooves are provided inside the two adjustment rods 302 and on the left and right sides of the movable groove 501 , and an internal slide rod extending to the slide groove is fixedly installed on the opposite sides of each two latch teeth 504 .

[0029] Specifically, the purpose of providing the sliding groove and the sliding rod is to avoid the distortion of the return spring 503 and improve the stability of the movement of the latching tooth 504.

[0030] Two straps are installed at both left and right ends of the top of the two arm support bodies 4, and each two straps are connected by a Velcro fleece surface and a Velcro hook surface.

[0031] Specifically, providing a strap, a Velcro fleece surface, and a Velcro hook surface can better fix the patient's arm.

[0032] When implementing, follow these steps:

[0033] 1) When adjusting the height of the arm support body 4, pull the movable rod 304 so that the movable rod 304 is out of the slot 307;

[0034] 2) Then move the adjustment rod 302 to a suitable position, insert the movable rod 304 into the slot 307, adjust the height of the arm support body 4, place the two arms of the patient on the arm support body 4, and fix the patient's arms by binding, Velcro fur surface and Velcro hook surface;

[0035] 3) Then manually move the arm support body 4;

[0036] 4) The movement of the arm support body 4 drives the rotating rod 502 to rotate in the movable groove 501. When the two gears 505 rotate, they contact the two latch teeth 504 to squeeze the return spring 503;

[0037] 5) Finally, the two gears 505 are limited by the two latching teeth 504 so that the angle of the arm support body 4 can be adjusted.

[0038] In summary, the new CT examination pillow with an arm support structure is provided with the pillow body 2, the fixing tube 301, the adjusting rod 302, the cavity 303, the movable rod 304 and the extrusion spring 305. When adjusting the height of the arm support body 4, the movable rod 304 can be pulled, and the movable rod 304 is disengaged from the slot 307. The position of the adjusting rod 302 can be moved according to the patient's usage. Thereafter, the movable rod 304 is inserted into the slot 307 to fix the adjusting rod 302. Then, the height of the arm support body 4 can be adjusted to meet the needs of different patients, improve the comfort of the patients and reduce discomfort.

[0039] In addition, by providing the movable groove 501, the rotating rod 502, the reset spring 503, the latch tooth 504 and the gear 505, when adjusting the tilt angle of the arm support body 4, the arm support body 4 is manually moved, and the movement of the arm support body 4 will drive the rotating rod 502 to rotate in the movable groove 501. Therefore, when the two gears 505 rotate, they will contact the two latch teeth 504. The two latch teeth 504 are used to compress the two reset springs 503. When the tilt angle is determined, the movement of the arm support body 4 can be stopped, and the two gears 505 are limited by the two latch teeth 504, so that the arm support body 4 is easy to adjust the tilt angle, thereby achieving the purpose of retraction and adjustment, and improving the practicality of the device.
