Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, specifically a multi-degree-of-freedom linkage radiological examination positioning and fixation nursing bed. Background Technology

[0002] Radiological examinations utilize ionizing radiation imaging technologies such as X-rays and computed tomography (CT) to penetrate human tissue and obtain images of internal organs and bone morphology, thereby assisting in the diagnosis of clinical diseases. Radiological examination positioning is a standardized body posture designed for different examination sites to ensure image clarity and diagnostic accuracy. The positioning and nursing bed is a special bed adapted to radiological examination scenarios, combining positioning adjustment, positioning fixation, and basic nursing functions. It can help patients maintain a standardized projection position, reduce imaging artifacts, and meet the examination needs of bedridden and critically ill patients, reducing the risk of transportation.

[0003] Existing radiological examination positioning care beds have certain shortcomings in lateral positioning support and adjustment capabilities. When performing radiological examinations in special positions such as lateral or oblique recumbent, it is often necessary to use external devices such as sandbags and soft pads to elevate and support the patient. The positioning procedure is relatively cumbersome, and the support stability is generally poor, making it easy for the patient to shift position during the examination. In addition, some lateral support structures cannot be completely flattened and stored, which affects the overall flatness of the bed surface during supine examinations and has a certain impact on the patient's lying comfort. The flexibility to adapt to various radiological examination scenarios needs to be further improved. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing radiological examination positioning beds in terms of lateral support and adjustment capabilities. When performing radiological examinations in special positions such as lateral or oblique recumbent, external devices such as sandbags and cushions are often required for elevation and support, making the positioning process cumbersome and the support stability generally poor, leading to potential positional shifts during the examination. Furthermore, some lateral support structures cannot be completely flattened and stowed away, affecting the overall flatness of the bed surface during supine examinations and impacting patient comfort. The flexibility in adapting to various radiological examination scenarios also needs further improvement. Therefore, this invention provides a multi-degree-of-freedom linkage radiological examination positioning bed.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0030] Reference Figure 1In this embodiment of the invention, a multi-degree-of-freedom linkage radiological examination positioning and nursing bed includes: a bed body 1, a first flipping component 2 on the bed body 1, a second flipping component 3 on the first flipping component 2, two sets of the first flipping component 2 are symmetrically distributed on the bed body 1, which can support the upper and lower body of the human body respectively and adjust the angle, and the second flipping component 3 can support the left and right sides of the human body and adjust the angle.

[0031] Reference Figure 2 The bed frame 1 includes a rectangular support frame 11. Support legs 12 are fixedly connected to the bottom of the support frame 11. Four sets of support legs 12 are symmetrically distributed at the bottom of the support frame 11. Support rods 13 are fixedly connected to the inner side of the support frame 11. Multiple sets of support rods 13 are distributed along the width of the rectangular support frame 11, and multiple sets of support rods 13 are located in the area from the waist to the root of the thigh when lying flat.

[0032] The above solution involves arranging multiple sets of support rods 13 along the width of the support frame 11 to precisely support the area from the waist to the root of the thigh. This maintains the physiological curvature of the patient's waist, improves lying comfort, ensures uniform support strength on the bed surface, and reduces the obstruction of radiation rays by the frame-type hollow structure, thus meeting the imaging requirements of radiological examinations.

[0033] Reference Figures 3 to 5The flipping component 2 includes a connecting block 21 fixedly connected to the bottom of the support frame 11. Two sets of connecting blocks 21 are symmetrically distributed at the bottom of the support frame 11. The connecting blocks 21 are L-shaped, and the two sets of connecting blocks 21 are mirror images of each other. The flipping component 2 also includes a rotating block 22, which is T-shaped, wider at the top and narrower at the bottom. The length of the upper part of the rotating block 22 is the same as the inner width of the support frame 11, and the length of the lower part of the rotating block 22 is the same as the distance between the two sets of connecting blocks 21. The lower part of the rotating block 22 is positioned between the two sets of connecting blocks 21, and the height of the lower part of the rotating block 22 is greater than half the total height of the connecting blocks 21. At one end of the lower part of the rotating block 22, a connecting hole 23 is formed through the width direction of the support frame 11. A limiting groove 24 is formed on the inner wall of the connecting hole 23. Multiple sets of limiting grooves 24 are evenly distributed within the connecting hole 23. The inner wall has a limiting groove 24 that passes through both ends of a connecting hole 23. A rotating rod 25 is installed through the connecting hole 23. A limiting plate 26 is fixedly connected to the outer surface of the rotating rod 25. Multiple sets of limiting plates 26 are evenly distributed on the outer surface of the rotating rod 25. Each set of limiting plates 26 is slidably inserted into a set of limiting grooves 24. The length of the rotating rod 25 is the same as the length of the connecting hole 23. The length of the limiting plate 26 is less than the length of the rotating rod 25. A screw 27 is fixedly connected to the end face of the rotating rod 25. The screw 27 passes through a connecting block 21 and is threadedly connected to the connecting block 21. Two sets of screws 27 are symmetrically distributed at both ends of the rotating rod 25. Each set of screws 27 is connected to a set of connecting blocks 21. One set of screws 27 passes through one end of the connecting block 21 and is fixedly connected to a nut 28.

[0034] The above scheme is adopted: two sets of mirrored L-shaped connecting blocks 21 provide stable rotation mounting points for the rotating block 22. The T-shaped rotating block 22 is adapted to the inner width of the support frame 11, ensuring sufficient rotation support area and conforming to the structure of the bed 1. The rotating rod 25 passes through the connecting hole 23, and the circumferential synchronous transmission is achieved by the insertion and cooperation of multiple sets of limiting plates 26 and limiting grooves 24. The angle is locked by the threaded connection between the screw 27 and the connecting block 21. The angle can be adjusted and fixed by rotating the nut 28. The adjustment accuracy is high and the locking is stable, which can avoid body position displacement during the examination and ensure the clarity and consistency of radiographic imaging.

[0035] Reference Figures 6 to 8The flipping component 2 3 includes a connecting frame 31 fixedly connected to the upper side of the rotating block 22. The connecting frame 31 is I-shaped, and a support plate 32 is provided on the side of the I-shaped connecting frame 31. The support plate 32 is D-shaped, and a connecting hole 2 33 is provided through the support plate 32 along the length direction of the rectangular support frame 11. The length of the connecting hole 2 33 is the same as the maximum length of the D-shaped support plate 32. A limiting groove 2 34 is provided on the inner wall of the connecting hole 2 33. Multiple sets of limiting grooves 2 34 are provided and evenly distributed on the inner wall of the connecting hole 2 33. The two ends of the limiting grooves 2 34 pass through the two ends of the connecting hole 2 33 respectively. A rotating rod 2 36 is provided through the connecting hole 2 33. A limiting plate 2 37 is fixedly connected to the outer circular surface of the rotating rod 2 36. Multiple sets of limit plates 37 are evenly distributed on the outer surface of the rotating rod 36. Each set of limit plates 37 is slidably inserted into a set of limit grooves 34. The length of the rotating rod 36 is the same as the length of the connecting hole 33. The length of the limit plate 37 is less than the length of the rotating rod 36. A screw 38 is fixedly connected to one end of the rotating rod 36 facing the rotating block 22. The screw 38 passes through the rotating block 22 and is threadedly connected to the rotating block 22. A nut 39 is fixedly connected to the other end of the rotating rod 36. A clearance groove 35 is opened at the top of the connecting frame 31. The clearance groove 35 is T-shaped. When the flipping part 3 is placed horizontally, the rotating rod 36 and the nut 39 are placed in the clearance groove 35. Two sets of support plates 32 are provided on each set of connecting frames 31.

[0036] The above solution is adopted as follows: the flipping component 2 3 is securely installed on the side of the rotating block 22 by the I-shaped connecting frame 31. The D-shaped support plate 32 can provide close support to the side of the human body. The rotating rod 2 36 is inserted into the connecting hole 2 33. The circumferential limit is achieved by the plug-in structure of the limiting plate 2 37 and the limiting groove 2 34. The angle is locked by the threaded connection between the screw 2 38 and the rotating block 22. The flipping angle of the support plate 32 can be adjusted by rotating the nut 2 39. The T-shaped clearance groove 35 can accommodate the rotating rod 2 36 and the nut 2 39 when the flipping component 2 3 is stored horizontally, ensuring that the bed surface is flat and without protrusions, avoiding pressure on the patient and improving lying comfort.

[0037] The working principle of this invention is as follows: When adjusting the body position, the flipping part 1 2 and flipping part 2 3 can be operated separately according to the needs of the examination site. When adjusting the angle of the flipping part 1 2, taking the flipping part 1 2 corresponding to the upper body of the patient as an example, the medical staff rotates the nut 28 at the end of the flipping part 1 2. The nut 28 drives the coaxial screw 27 to rotate synchronously. The screw 27 is displaced along the axial direction of the connecting hole 23 through the threaded engagement with the connecting block 21, thereby driving the rotating rod 25 to move axially synchronously. Multiple sets of limiting plates 26 on the outer circular surface of the rotating rod 25 are fitted into the limiting groove 24 on the inner wall of the connecting hole 23. While moving axially, the rotating block 22 is rotated around the axis of the rotating rod 25 through the circumferential locking action, so that the support surface above the rotating block 22 is raised or lowered, thereby realizing the adjustment of the upper body pitch angle. The adjustment method of the flipping part 1 2 corresponding to the lower body of the patient is the same as that of the upper body. The two sets of flipping parts 1 2 can be adjusted independently without interfering with each other.

[0038] When adjusting the angle of the flipping component 3, operate the corresponding side support plate 32 according to the body position requirements: rotate the nut 39 on the outer side of the support plate 32. The nut 39 drives the rotating rod 36 to rotate synchronously. The screw 38 at the end of the rotating rod 36 moves axially towards the inside or outside of the rotating block 22 through threaded engagement with the rotating block 22. The limiting plate 37 outside the rotating rod 36 slides along the limiting groove 34. Through circumferential engagement, it drives the support plate 32 to flip around the axis of the rotating rod 36, realizing the lateral support angle. When adjusting for examinations such as chest lateral view and spinal lateral view, assist the patient to lie on the affected side, and then adjust the support plate 32 of the opposite side flipping part 3 to lift it, providing stable lateral support against the patient's back. The standard lateral lying position can be maintained without manual assistance. When lateral support is not needed, rotate the nut 39 to reset the support plate 32 to a horizontal state. At this time, the end of the rotating rod 36 and the nut 39 are embedded in the T-shaped relief groove 35 at the top of the connecting frame 31, ensuring that the bed surface is flat and will not cause pressure or discomfort to the patient.

[0039] The device can be adjusted in combination for different radiological examination scenarios: For routine chest X-ray examination in the anteroposterior position, both sets of flipping parts 1 and 2 are adjusted to the horizontal position, and the flipping parts 2 and 3 on both sides are simultaneously stored. The chest can be fixed with the strap. For spinal oblique position examination, the lifting angle of the flipping part 2 and 3 on one side and the pitch angle of the flipping part 1 and 2 are adjusted together to quickly position the patient to the standard oblique position. For examination of bedridden critically ill patients, the flipping part 1 and 2 can be adjusted to adapt to the patient's tolerable position, eliminating the need to repeatedly move the patient. After the examination is completed, the screws are slowly turned to gradually reset the flipping parts 1 and 2 and 3 to the horizontal position and lock them. After confirming that all parts are in place, the patient is assisted to get out of bed or to complete the transfer, and the examination process is completed.

[0040] Two sets of flip-up components 2 are symmetrically distributed on the bed 1, allowing independent angle adjustment of the upper and lower body to flexibly adapt to the positioning requirements of different radiological examinations such as chest X-rays, abdominal X-rays, and spinal X-rays. After adjustment, the angle can be locked stably to prevent body position from shifting during the examination, effectively improving the clarity and standardization of radiological imaging, while reducing the workload of medical staff in manual positioning. Flip-up components 2 are set on the left and right sides of the body to provide support and restraint for the patient's torso, helping the patient maintain special examination positions such as lateral and oblique lying without the need for additional sandbags or manual support. When not in use, they can be stored horizontally to keep the bed surface flat, taking into account both the body position adjustment function and the patient's lying comfort, and adapting to the positioning requirements of various radiological examination scenarios.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
