Description

Technical Field

[0001] The present application relates to the technical field of posture correction, and more specifically, to a chest X-ray posture correction device. Background Art

[0002] Chest X-rays in the radiology department are mainly used clinically to examine parts such as the chest wall, lungs, pleural cavity, heart, etc. For example, diseases such as pneumonia, pleural effusion, and rib fractures can be preliminarily screened through chest X-rays. During the filming process, the patient needs to place their hands behind their back against the waist, open their shoulders, and hold their head high. The entire photographing process requires maintaining a certain posture for a period of time, and the oral instructions are cumbersome. Sometimes, the patient cannot understand well.

[0003] The prior art document with the publication number CN 220293604 U provides a chest X-ray posture correction device for the radiology department. This device consists of a shoulder calibration pillow composed of a calibration crossbar and a shoulder positioning pillow. The shoulder positioning pillow is installed based on the inner side screw of the calibration crossbar, and the height of the adjusting vertical rod is adjusted so that the shoulder muscles can touch the shoulder positioning pillow of the shoulder calibration pillow. At this time, the shoulders are in a fully open state backward.

[0004] Although the above prior art solution can achieve the relevant beneficial effects through the structure of the prior art, there are still the following defects: when using this device, it is necessary to fix the entire correction device on the user's body, which will increase the burden on the patient. For patients with physical discomfort and unstable standing, it is even more impossible to ensure the stability of standing.

[0005] In view of this, we propose a chest X-ray posture correction device. Utility Model Content

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] A chest X-ray posture correction device comprises: a U-shaped frame 1 with an opening facing upward and a lifting mechanism 5, a standing board 2 is vertically fixed to the bottom of the U-shaped frame 1, the U-shaped frame 1 comprises two parallel vertical pipes 102, the lifting mechanism 5 comprises a slider 501 slidably arranged on the vertical pipes 102, an arm support rod 3 is fixedly installed on the slider 501, a back limit rod 4 is detachably provided between the two arm support rods 3, and the installation positions of the back limit rod 4 and the arm support rod 3 are adjustable.

[0030] Reference Figures 1 - 5 , install two vertical pipes 102 on both sides of the X-ray machine 7, and support the arm support rod 3 on the detection surface of the X-ray machine 7. The patient stands on the standing board 2 with the chest against the detection surface of the X-ray machine 7, spreads the arms, and supports the patient's arms or armpits by sliding the two sliders 501 downward synchronously to improve the patient's stability when standing. Then fix the back limit rod 4 on the arm support rod 3, and the back limit rod 4 is attached to the back to ensure that the chest is attached to the X-ray machine 7, completing the posture correction while supporting the patient.

[0031] The U-shaped frame 1 also includes a transverse tube 101, and a vertical tube 102 is vertically fixed at both ends of the transverse tube 101. The vertical tube 102 is provided with a slide groove 1021 adapted to the slider 501. The lifting mechanism 5 also includes a servo motor 503 and a transmission shaft 504 that is driven by the servo motor 503 and rotatably connected to the transverse tube 101, and two screw rods 502 that are rotatably connected to the vertical tube 102 respectively. The screw rod 502 is threadedly connected to the slider 501, and the two screw rods 502 are drivingly connected to the transmission shaft 504.

[0032] Reference Figures 2 - 4, a fixing plate 1022 is fixedly installed in the riser 102. Both ends of the lead screw 502 are rotatably connected to the riser 102 and the fixing plate 1022 through bearings 5022. The transmission shaft 504 is rotatably connected to the horizontal pipe 101 through the bearing 5022. The servo motor 503 drives the transmission shaft 504 to rotate, and the transmission shaft 504 drives the two lead screws 502 to rotate synchronously in the same direction. Furthermore, the slider 501 can slide up and down along the chute 1021 to adjust the lifting of the arm support rod 3 finally.

[0033] One end of the transmission shaft 504 is coaxially fixed to the output shaft of the servo motor 503. The servo motor 503 is fixed at one end of the horizontal pipe 101. Two driving bevel gears 5041 are coaxially fixed on the transmission shaft 504. A driven bevel gear 5021 meshing with the driving bevel gear 5041 is coaxially fixed at the lower end of the lead screw 502.

[0034] Refer to Figure 4 and Figure 5 , after the servo motor 503 is powered on and operates, it can drive the transmission shaft 504 to rotate. The transmission shaft 504 drives the two driving bevel gears 5041 with the same specifications and in the same direction to rotate synchronously. Then, the two driving bevel gears 5041 respectively drive the two driven bevel gears 5021 with the same specifications to rotate, and further drive the two lead screws 502 with the same specifications to rotate in the same direction to adjust, and finally make the two sliders 501 lift and adjust synchronously.

[0035] A plurality of card slots 301 adapted to the back limiting rod 4 are formed on the upper surface of the arm support rod 3. Limit blocks 401 are vertically fixed at both ends of the back limiting rod 4.

[0036] Refer to Figure 1 and Figure 3 and Figure 5 , after the patient stands on the standing plate 2 and presses the chest against the detection surface of the X-ray fluoroscope 7, then the back limiting rod 4 is inserted into the corresponding card slot 301, and the back limiting rod 4 is made to abut against the back of the patient to ensure the fitting of the patient's chest with the X-ray fluoroscope 7. At the same time, the two limit blocks 401 are placed outside the arm support rod 3 to prevent the back limiting rod 4 from horizontally disengaging from the card slot 301.

[0037] Sponge pads 6 are fixedly installed on the upper surface of the arm support rod 3 and on the side of the back limiting rod 4 close to the back.

[0038] Refer to Figure 3 and Figure 5 , the sponge pad 6 is fixed on the upper surface of the arm support rod 3 to improve the support comfort of the arm support rod 3 for the arm or armpit. At the same time, the sponge pad 6 is fixed on the side of the back limiting rod 4 close to the patient's back to improve the comfort when the back limiting rod 4 abuts against the patient's back.

[0039] Working principle: After removing the back limiting rod 4 from the arm support rod 3, the patient stands on the standing board 2, and with the chest against the detection surface of the X-ray fluoroscope 7, the arms are extended. After the servo motor 503 is powered on and runs, it drives the transmission shaft 504 to rotate. The transmission shaft 504 drives the driving bevel gear 5041 to rotate synchronously. Then, the two driving bevel gears 5041 respectively drive the driven bevel gears 5021 to rotate, driving the two same-specification lead screws 502 to rotate in the same direction for adjustment. The two sliders 501 rise synchronously to support the patient's arms or armpits. Subsequently, the back limiting rod 4 is inserted into the corresponding card slot 301, and the sponge pad 6 on the side of the back limiting rod 4 is pressed against the patient's back.
