Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a radiographic adjustment device. Background Technology

[0002] Contrast radiography is a medical imaging technique that uses X-rays or other radioactive substances (such as iodinated contrast agents) to image the interior of the human body to observe and diagnose lesions. Contrast radiography provides crucial imaging evidence for interventional medical procedures. Through this technique, doctors can clearly see the blood vessels, cavities, and lesion sites within the patient's body, providing precise location and navigation for interventional treatments. A contrast radiography adjustment device is an auxiliary device used during medical contrast radiography. Its main functions are to adjust and fix the patient's position, as well as adjust the position and angle of the contrast equipment to ensure the clarity and accuracy of the contrast images.

[0003] During contrast radiography, medical staff may ask patients to change positions in order to clearly and accurately observe the blood vessels, cavities, and lesions in the patient's body. The semi-recumbent position is a special position that may be used in certain contrast radiography examinations, but its stability and patient comfort may be relatively poor, and patients may not be able to maintain stability for the imaging. Therefore, a contrast radiography adjustment device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that patients are not easy to maintain stability when taking radiographic images in a semi-recumbent position. This invention provides a radiographic adjustment device.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A radiographic adjustment device includes a base, a bed fixedly mounted on the top of the base, a support arm fixedly mounted on the side wall of the base, an imaging mechanism fixedly mounted on the support arm, two grooves on the top of the bed, a rotating plate movably mounted inside each groove, and a drive mechanism for tilting the rotating plate inside each groove, a headrest on the top of the bed, a transmission mechanism for driving the headrest to reciprocate linearly inside the bed, a pedal first on the top of the bed, a moving mechanism for driving the pedal to reciprocate linearly inside the bed, and a detachable pedal second on the side of the pedal near the headrest.

[0007] Furthermore, the drive mechanism includes a slide groove, and each groove has a slide groove on its inner bottom surface. Servo motors are fixedly installed on both sides of the bed. The output end of each servo motor extends into the interior of the adjacent slide groove and is fixedly connected to a lead screw. Each lead screw is threadedly connected to a slider. Rotating rods are rotatably connected to both sides of each slider. A C-shaped frame is fixedly installed at the bottom of each rotating plate. The free end of each rotating rod is rotatably connected to the adjacent C-shaped frame.

[0008] Furthermore, the driving mechanism also includes a second slide groove, with a second slide groove provided on the inner bottom surface of each first slide groove, and a second slide groove fixedly installed on the bottom of each first slide block, with each second slide block movably installed inside the adjacent second slide groove.

[0009] Furthermore, the transmission mechanism includes a convex groove, a convex groove is provided on the top of the bed, a threaded rod is movably installed inside the convex groove, a handwheel for driving the threaded rod to rotate is movably installed on the side wall of the bed, a convex block is threadedly connected to the threaded rod, and a headrest is fixedly installed on the top of the convex block.

[0010] Furthermore, the moving mechanism includes a second convex groove, the top of the bed has a second convex groove, a second threaded rod is movably installed inside the second convex groove, a second handwheel for driving the second threaded rod to rotate is movably installed on the side wall of the bed, a second convex block is threadedly connected to the second threaded rod, and a first pedal is fixedly installed on the top of the second convex block.

[0011] Furthermore, a slot is provided on the side of the pedal two near the headrest, and a locking rod is movably installed inside the slot. The pedal two is fixedly connected to the pedal two. Several equally spaced diagonal rods are fixedly installed on the side of the pedal two away from the headrest. A positioning groove is provided on the top of the pedal one, and a positioning rod is movably installed inside the positioning groove. The end of each diagonal rod away from the pedal two is fixedly connected to the positioning rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Due to significant height differences among patients, this utility model allows for adjustments to the transmission mechanism to move the headrest to a suitable position, and then to the movement mechanism to move pedals one and two to the appropriate positions. This ensures the patient's head rests on the headrest and their feet are positioned on the side of pedal two closest to the headrest. The headrest and pedal two restrict the patient's supine position, ensuring accurate X-ray imaging. If medical staff require the patient to assume a semi-lateral recumbent position while supine for radiography, further adjustments can be made to ensure stability during the X-ray process. A set of drive mechanisms is required to control the semi-lateral recumbent position, thereby rotating the corresponding rotating plate to an inclined state. The tilted rotating plate pushes the patient's back up, allowing the patient to assume a semi-lateral recumbent position. The support of the rotating plate helps the patient maintain stability in the semi-lateral recumbent position for X-rays. If medical staff require the patient to bend their knees at a certain angle, the patient should first lie flat on the bed surface, and then bend their knees while placing their feet on the top of pedal one. By controlling the moving mechanism, the position of pedal one can be adjusted to adjust the angle of the bent knees to a suitable angle. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 4As shown, a radiographic adjustment device includes a base 1, a bed 2 fixedly mounted on the top of the base 1, a support arm 3 fixedly mounted on the side wall of the base 1, an imaging mechanism 4 fixedly mounted on the support arm 3, two grooves 5 on the top of the bed 2, a rotating plate 6 movably mounted inside each groove 5, and a drive mechanism 7 for tilting the rotating plate 6 inside each groove 5, a headrest 8 on the top of the bed 2, a transmission mechanism 9 for driving the headrest 8 in linear reciprocating motion inside the bed 2, a pedal 10 on the top of the bed 2, and a moving mechanism 11 for driving the pedal 10 in linear reciprocating motion inside the bed 2, and a detachable pedal 12 on the side near the headrest 8. It should be noted that, due to the large height difference between different patients, to ensure that the patient lies flat in a suitable area on the bed 2, the headrest 8 can be moved to a suitable position by adjusting the transmission mechanism 9, and then the pedal 10 can be moved to a suitable position by adjusting the moving mechanism 11. The first board 10 and the second pedal 12 are moved to a suitable position so that the patient's head rests on the headrest 8 and the soles of the feet are on the side of the second pedal 12 closest to the headrest 8. The headrest 8 and the second pedal 12 restrict the patient's supine area to ensure accurate X-ray. When the patient lies supine on the bed 2 for radiography, if the medical staff requires the patient to be in a semi-recumbent position, in order to ensure the patient's stability during X-ray, a set of drive mechanisms 7 can be controlled according to the required semi-recumbent direction to rotate the corresponding rotating plate 6 to an inclined state. The rotating plate 6, which is rotated to an inclined state, pushes the patient's back up, so that the patient can be in a semi-recumbent position. The support of the rotating plate 6 can help the patient maintain stability in the semi-recumbent position for X-ray. If the medical staff requires the patient to bend their knees at a certain angle, the patient is first laid supine on the surface of the bed 2, and then the knees are bent while the soles of the feet are on the top of the first pedal 10. The position of the first pedal 10 can be adjusted by controlling the moving mechanism 11 to adjust the angle of the bent knees to a suitable angle.

[0024] like Figure 1 , Figure 2As shown, the drive mechanism 7 includes a slide groove 701. Each groove 5 has a slide groove 701 on its inner bottom surface. Servo motors 702 are fixedly installed on both sides of the bed 2. The output end of each servo motor 702 extends into the interior of the adjacent slide groove 701 and is fixedly connected to a lead screw 703. Each lead screw 703 is threadedly connected to a slider 704. Rotating rods 705 are rotatably connected to both sides of each slider 704. A C-shaped frame 706 is fixedly installed at the bottom of each rotating plate 6. The free end of each rotating rod 705 is rotatably connected to the adjacent C-shaped frame 706. It should be noted that by starting the servo motor 702, the corresponding lead screw 703 can be reciprocated. The reciprocating rotation of the lead screw 703 can cause the corresponding slider 704 to move linearly back and forth. While the slider 704 is moving, it can also cause the two corresponding rotating rods 705 to rotate. The two rotating rods 705 can push the corresponding C-shaped frame 706 and the rotating plate 6, thereby causing the rotating plate 6 to rotate at different tilt angles.

[0025] like Figure 1 , Figure 2 As shown, the driving mechanism 7 also includes a second slide groove 707. The bottom surface of each first slide groove 701 is provided with a second slide groove 707. The bottom of each first slider 704 is fixedly installed with a second slider 708. Each second slider 708 is movably installed inside the adjacent second slide groove 707. It should be noted that when the first slider 704 moves, it can drive the second slider 708 connected to it to slide inside the corresponding second slide groove 707. The movement trajectory of the first slider 704 can be restricted by the cooperation of the second slide groove 707 and the second slider 708.

[0026] like Figure 1 , Figure 2 As shown, the transmission mechanism 9 includes a convex groove 901. The top of the bed 2 has a convex groove 901. A threaded rod 903 is movably installed inside the convex groove 901. A handwheel 902 for driving the threaded rod 903 to rotate is movably installed on the side wall of the bed 2. A convex block 904 is threadedly connected to the threaded rod 903. The headrest 8 is fixedly installed on the top of the convex block 904. It should be noted that by reciprocating the handwheel 902, the threaded rod 903 can be reciprocated, thereby causing the convex block 904 to move linearly back and forth. The movement of the convex block 904 can simultaneously drive the headrest 8 to move.

[0027] like Figure 1 , Figure 3As shown, the moving mechanism 11 includes a convex groove 1101. The top of the bed 2 has a convex groove 1101. A threaded rod 1103 is movably installed inside the convex groove 1101. A handwheel 1102 for driving the threaded rod 1103 to rotate is movably installed on the side wall of the bed 2. A convex block 1104 is threadedly connected to the threaded rod 1103. A pedal 10 is fixedly installed on the top of the convex block 1104. It should be noted that by reciprocating the handwheel 1102, the threaded rod 1103 can be reciprocated, thereby causing the convex block 1104 to move linearly back and forth. The movement of the convex block 1104 can simultaneously drive the pedal 10 to move.

[0028] like Figure 1 , Figure 3 , Figure 4 As shown, a slot 13 is provided on the side of pedal 2 12 near the headrest 8. A locking rod 14 is movably installed inside the slot 13. Pedals 2 12 are fixedly connected to each other. Several equidistant diagonal rods 15 are fixedly installed on the side of pedal 2 12 away from the headrest 8. A positioning groove 17 is provided on the top of pedal 10. A positioning rod 16 is movably installed inside the positioning groove 17. The end of each diagonal rod 15 away from pedal 2 12 is fixedly connected to the positioning rod 16. It should be noted that by pulling pedal 2 12, the locking rod 14 can be slid out from inside the slot 13, and the positioning rod 16 can be slid out from inside the positioning groove 17. Pedals 2 12 can be disassembled to make it convenient for the patient to step on the top of pedal 10. When the patient's foot is in contact with the side of pedal 2 12 near the headrest 8, the diagonal rods 15 can provide effective support.

[0029] In summary:

[0030] Due to significant height differences among patients, to ensure patients can lie flat in a suitable position on bed 2, the headrest 8 can be moved to a suitable position by adjusting the transmission mechanism 9. Then, the footrests 10 and 12 can be moved to suitable positions by adjusting the moving mechanism 11, so that the patient's head rests on the headrest 8 and their feet are on the side of footrest 12 closest to the headrest 8. The headrest 8 and footrest 12 restrict the patient's lying area to ensure accurate X-ray imaging. When the patient is lying flat on bed 2 for radiography, if medical staff require the patient to assume a semi-lateral recumbent position, further adjustments can be made to ensure patient stability during X-ray imaging. A set of drive mechanisms 7 is required to control the semi-recumbent position so that the corresponding rotating plate 6 can be rotated to an inclined state. The rotating plate 6, which is rotated to an inclined state, pushes the patient's back up so that the patient can be in a semi-recumbent position. The support of the rotating plate 6 can help the patient maintain stability in the semi-recumbent position for X-ray. If the medical staff asks the patient to bend their knees at a certain angle, the patient should first lie flat on the surface of the bed 2, and then bend their knees while stepping on the top of the pedal 10. The position of the pedal 10 can be adjusted by controlling the moving mechanism 11 so that the angle of the knees is adjusted to a suitable angle.

[0031] Due to significant height differences among patients, to ensure patients can lie flat in a suitable position on bed 2, the headrest 8 can be moved to a suitable position by adjusting the transmission mechanism 9. Then, the footrests 10 and 12 can be moved to suitable positions by adjusting the moving mechanism 11, so that the patient's head rests on the headrest 8 and their feet are on the side of footrest 12 closest to the headrest 8. The headrest 8 and footrest 12 restrict the patient's lying area to ensure accurate X-ray imaging. When the patient is lying flat on bed 2 for radiography, if medical staff require the patient to assume a semi-lateral recumbent position, further adjustments can be made to ensure patient stability during X-ray imaging. A set of drive mechanisms 7 is required to control the semi-recumbent position so that the corresponding rotating plate 6 can be rotated to an inclined state. The rotating plate 6, which is rotated to an inclined state, pushes the patient's back up so that the patient can be in a semi-recumbent position. The support of the rotating plate 6 can help the patient maintain stability in the semi-recumbent position for X-ray. If the medical staff asks the patient to bend their knees at a certain angle, the patient should first lie flat on the surface of the bed 2, and then bend their knees while stepping on the top of the pedal 10. The position of the pedal 10 can be adjusted by controlling the moving mechanism 11 so that the angle of the knees is adjusted to a suitable angle.
