Abstract
Description
Technical Field
[0001] This invention relates to the field of medical auxiliary device technology, specifically a special bed for gastrointestinal diagnostic ultrasound contrast imaging. Background Technology
[0002] Contrast-enhanced ultrasound is an imaging technique that significantly enhances the contrast and resolution of ultrasound images by intravenously injecting microbubble contrast agents. It can dynamically display the blood perfusion of tissue microcirculation in real time, playing a crucial role in differentiating between benign and malignant tumors, assessing cardiovascular diseases, and guiding interventional treatments. In examinations such as gastrointestinal contrast-enhanced ultrasound, patient positioning often needs to be adjusted, such as turning or tilting, to optimize imaging results. This places special demands on the positional support of the examination bed and the coordination of the operator. However, existing contrast-enhanced ultrasound equipment still has significant shortcomings in terms of user-friendly design and system reliability.
[0003] The lack of coordination between the patient positioning adjustment function and the control panel posture control of existing examination beds leads to interruptions and inefficiencies in the operation process for medical staff. When adjusting the patient's position, if the bed tilts or flips, the control panel fixed to the bed will rotate synchronously with the bed board, forcing medical staff to frequently adjust their operating posture or manually recalibrate the control panel angle. For example, in examinations that require multiple changes in patient position to observe the distribution of gastrointestinal contrast agents, this non-coordinated design disrupts the continuity of the operation, increases examination time, and may lead to accidental touches or incorrect settings due to an unsuitable control panel angle, affecting diagnostic efficiency and stability.
[0004] Existing console posture maintenance mechanisms rely on external power sources such as electric or hydraulic drives, which presents challenges such as response delays, system failure risks, and energy consumption issues. While some high-end devices are equipped with console angle adjustment functions, these often employ independent motors or hydraulic systems, resulting in complex structures, high costs, and susceptibility to response delays or malfunctions due to circuit failures, signal interference, or mechanical wear. In medical settings with complex electromagnetic environments, such active control systems may also interfere with the signal acquisition of the ultrasound equipment itself. Furthermore, the additional power source increases equipment energy consumption and maintenance burden, failing to meet the core requirement of long-term reliability in medical settings. Summary of the Invention
[0005] The purpose of this invention is to provide a special bed for gastrointestinal diagnostic ultrasound contrast imaging to solve the problems mentioned in the background art.

[0011] Furthermore: the lifting assembly includes a lifting frame, a third motor, and a lead screw.

[0012] Furthermore: the installation components include a lifting plate and an installation platform, the lifting plate being threaded onto the outer wall of the lead screw, and the installation platform being fixedly installed at the bottom of the lifting plate.
[0013] Furthermore: the standing assembly includes two connecting seats and a standing plate, each connecting seat being fixedly installed on the outer wall of the bed board, and the standing plate being fixedly installed inside the two connecting seats.
[0014] Furthermore: the limiting components include a connecting plate, a limiting groove, a roller, and a drive gear. The connecting plate is fixedly installed on the outer wall of the support column, the limiting groove is opened on the outer wall of the connecting plate, the roller is slidably connected inside the limiting groove, and the drive gear is rotatably connected to the connecting end of the roller.
[0015] Furthermore: the transmission assembly includes a rotating seat, an arc-shaped rack, a transmission shaft, and a control console.

[0016] The beneficial effects of this invention are: 1. The flipping mechanism of this device constructs a purely mechanical, automated reverse compensation system through the precise coordination of the limiting and transmission components. Its core value lies in the fact that regardless of how the bed board is flipped to adjust the patient's position, the control panel on it remains horizontal, greatly facilitating operation by medical staff. Its working mechanism is as follows: when the drive component flips the bed board, it simultaneously drives the sliding frame with a fixed rotating seat to rotate. The rotating seat drives the drive gear to generate a revolution tendency via the transmission shaft. However, the drive gear always maintains engagement with the arc-shaped rack fixed to the stationary connecting plate, while the rollers on its shaft are confined within the limiting groove of the connecting plate. This constraint forces the drive gear to rotate on its own axis while revolving around the bed. The rotational motion of the drive gear is precisely transmitted to the control panel via the transmission shaft, driving it to generate a rotational motion with the same angle as the bed board's flipping but in the opposite direction. The most direct benefit of this purely mechanical linkage system is the ease of operation and safety. It achieves the intelligent effect of the bed moving while the console remains stationary. Medical staff do not need to readjust the angle of the console or their own operating posture after the bed position changes, and can continue to perform examinations with focus. This advantage is especially obvious when performing gastrointestinal imaging examinations that require frequent changes in body position.
[0017] 2. The most significant innovation of this tilting mechanism lies in its design without an additional power source. The horizontal holding function of the console requires no additional motor, sensor, or control system. Its energy is entirely derived from the mechanical energy generated by the tilting motion of the bed board itself. The entire compensation process is a passively responsive mechanical motion, with energy transferred and converted within the mechanism. This design brings several significant advantages: First, it greatly simplifies the electrical and control systems, eliminating the need for separately configured drives and control units for console rotation, significantly reducing manufacturing costs and system complexity. Second, due to its purely mechanical structure, its response is direct and reliable, eliminating the risk of electronic signal delays, program errors, or sensor failures, resulting in low maintenance requirements and higher stability and reliability in medical environments. Simultaneously, this energy recovery and reuse concept also reflects a highly efficient energy-saving design. Attached Figure Description

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.
[0030] Example 1: The present invention provides a technical solution, such as... Figures 1-8 As shown, a special bed for gastrointestinal diagnostic ultrasound contrast imaging includes a base 1, as well as a basic mechanism, an installation mechanism and a tilting mechanism; The basic mechanism is located on the top of the base 1. The basic mechanism includes a drive component, a lying component, a standing component, and a counterweight component. The drive component and the counterweight component are both located on the top of the base 1. The lying component is located on the drive component, and the standing component is located on the lying component. The mounting mechanism is mounted on the lying-flat component. The mounting mechanism includes a sliding component, a lifting component, and a mounting component. The sliding component is mounted on the lying-flat component, the lifting component is mounted on the sliding component, and the mounting component is mounted on the lifting component. The flipping mechanism is mounted on the drive assembly. The flipping mechanism includes a limiting assembly and a transmission assembly. The limiting assembly is mounted on the drive assembly, and the transmission assembly is mounted on the limiting assembly.
[0031] like Figures 1-2As shown, the drive assembly includes a support column 2, a mounting base 3, a first motor 4, a drive gear 5, a connecting shaft 6, and a driven gear 7. The support column 2 is fixedly mounted on the top of the base 1, the mounting base 3 is fixedly mounted on the outer wall of the support column 2, the first motor 4 is fixedly mounted on the top of the mounting base 3, the drive gear 5 is fixedly mounted on the output end of the first motor 4, the connecting shaft 6 is rotatably connected to the outer wall of the support column 2, and the driven gear 7 is fixedly mounted on the side end of the connecting shaft 6. The driven gear 7 meshes with the drive gear 5. This drive assembly is the core power source for changing the bed's posture. The support column 2 provides stable vertical support for the entire assembly. When the first motor 4 is started, its output end drives the drive gear 5 to rotate. Since the drive gear 5 meshes with the driven gear 7 fixed on the connecting shaft 6, the rotation of the drive gear 5 transmits power to the driven gear 7, thereby driving the connecting shaft 6 to rotate around its own axis on the outer wall of the support column 2. This rotational movement of the connecting shaft 6 provides a direct torque input for the subsequent tilting action of the lying-flat assembly.
[0032] like Figure 1 As shown, the supine assembly includes a driven seat 8 and a bed board 9. The driven seat 8 is rotatably connected to the outer wall of the support column 2, and the outer wall of the driven seat 8 is fixedly connected to the other end of the connecting shaft 6. The bed board 9 is fixedly installed on the outer wall of the driven seat 8. The supine assembly is the direct actuator for changing the posture of the patient's bearing surface. Since the driven seat 8 is fixedly connected to the connecting shaft 6 of the drive assembly, when the connecting shaft 6 is driven to rotate, it will synchronously drive the entire driven seat 8 to rotate. The bed board 9, fixed to the driven seat 8, moves accordingly, thereby realizing the continuous flipping of the bed board 9 from a horizontal position to an inclined or vertical position to adapt to the needs of patients in different positions such as supine, semi-recumbent, or standing during gastrointestinal ultrasound contrast imaging examinations.
[0033] like Figures 1-2 As shown, the counterweight assembly includes a counterweight groove 10 and a counterweight block 11. The counterweight groove 10 is formed on the outer wall of the base 1, and the counterweight block 11 is fixedly connected inside the counterweight groove 10. When the lying-flat assembly is flipped under the action of the drive assembly, especially when adjusting to a standing posture, a large overturning moment is generated. The counterweight block 11, fixed in the counterweight groove 10 of the base 1, uses its own weight to apply a stabilizing moment to the base 1 in the opposite direction to the load moment of the bed board 9, thereby effectively balancing the overall structure, preventing the equipment from tipping over due to the shift of the center of gravity, and ensuring the stability and safety of the bed during operation. The counterweight block 11 can also be replaced to adapt to different weight loads.
[0034] like Figures 1-4As shown, the sliding assembly includes a sliding frame 12, a second motor 13, two sprockets 14, a transmission belt 15, two slide rails 16, and a sliding plate 17. The sliding frame 12 is fixedly mounted on the outer wall of the bed board 9. The second motor 13 is fixedly mounted on the outer wall of the sliding frame 12. Each sprocket 14 is rotatably connected inside the sliding frame 12. The output end of the second motor 13 is fixedly connected to the side end of one of the sprockets 14. The transmission belt 15 is sleeved on the outer walls of the two sprockets 14. Each slide rail 16 is fixedly mounted on the outer wall of the sliding frame 12. The sliding plate 17 is slidably connected to the outer walls of the two slide rails 16. The outer wall of the sliding plate 17 is fixedly connected to the outer wall of the transmission belt 15. When it is necessary to adjust the horizontal position of the mounting assembly, the second motor 13 is activated. The second motor 13 drives the sprocket 14 connected to its output end to rotate. This sprocket 14 drives the other sprocket 14 to rotate synchronously through the transmission belt 15. Since the sliding plate 17 is fixedly connected to the outer wall of the transmission belt 15, the linear motion of the transmission belt 15 will be directly converted into the horizontal reciprocating movement of the sliding plate 17 along the two fixed slide rails 16, thereby driving the lifting assembly and mounting assembly installed on it to be precisely positioned in the length direction of the bed board 9.
[0035] like Figures 1-5 As shown, the lifting assembly includes a lifting frame 18, a third motor 19, and a lead screw 20. The lifting frame 18 is fixedly mounted on the outer wall of the sliding plate 17, and the third motor 19 is fixedly mounted on the outer wall of the lifting frame 18. The lead screw 20 is rotatably connected inside the lifting frame 18, and the output end of the third motor 19 is fixedly connected to the side end of the lead screw 20. When it is necessary to adjust the vertical height of the installation assembly, the third motor 19 is activated. The third motor 19 drives the lead screw 20 at its output end to rotate around its own axis within the lifting frame 18. The rotational movement of the lead screw 20 provides the power basis for the lifting and lowering of the installation assembly, and its rotation direction determines the subsequent lifting and lowering direction of the installation assembly.
[0036] like Figures 1-5 As shown, the mounting assembly includes a lifting plate 21 and a mounting platform 22. The lifting plate 21 is threadedly connected to the outer wall of the lead screw 20, and the mounting platform 22 is fixedly installed at the bottom of the lifting plate 21. When the lead screw 20 in the lifting assembly rotates, because the lifting plate 21 and the lead screw 20 are threadedly connected, and the lifting plate 21 is constrained by the lifting frame 18 and cannot rotate, the rotational motion of the lead screw 20 is converted into a linear lifting motion of the lifting plate 21 along the axis of the lead screw 20. The lifting plate 21 drives the mounting platform 22 at its bottom to move vertically synchronously, thereby precisely adjusting the spatial height of the mounting platform 22 to adapt to the needs of patients of different body sizes or different examination sites. The mounting platform 22 is used to fix the external ultrasound probe.
[0037] like Figure 1As shown, the standing assembly includes two connecting seats 23 and a standing plate 24. Each connecting seat 23 is fixedly mounted on the outer wall of the bed board 9, and the standing plate 24 is fixedly mounted inside the two connecting seats 23. When the supine assembly is driven by the drive assembly to flip from a supine position to a near-vertical standing position, the standing assembly fixed to the bed board 9 moves accordingly. The two connecting seats 23 provide a stable support connection for the standing plate 24, so that the standing plate 24 ultimately presents as a platform for the patient to step on. This structure provides a stable standing plane for the patient when the bed board 9 is tilted, allowing the patient to undergo gastrointestinal ultrasound imaging in a safe and stable posture.
[0038] like Figures 1-8 As shown, the limiting component includes a connecting plate 26, a limiting groove 27, a roller 28, and a drive gear 29. The connecting plate 26 is fixedly mounted on the outer wall of the support column 2. The limiting groove 27 is formed on the outer wall of the connecting plate 26. The roller 28 is slidably connected inside the limiting groove 27. The drive gear 29 is rotatably connected to the connecting end of the roller 28. This component is the key constraint part for the tilting mechanism to achieve its function. The connecting plate 26 is fixed to the support column 2, and its position remains unchanged during bed operation. The roller 28 is mounted on the shaft of the drive gear 29 and embedded in the limiting groove 27 of the connecting plate 26. When the transmission component associated with the drive gear 29 is displaced due to the tilting of the bed 9, the roller 28 is restricted to sliding only within the trajectory of the limiting groove 27. This constraint ensures that the trajectory of the drive gear 29 is precisely limited while it is revolving, thus creating the necessary conditions for subsequent meshing transmission.
[0039] like Figures 1-7As shown, the transmission assembly includes a rotating seat 25, an arc-shaped rack 30, a transmission shaft 31, and a control console 32. The rotating seat 25 is fixedly mounted on the outer wall of the sliding frame 12, the arc-shaped rack 30 is fixedly mounted on the outer wall of the connecting plate 26, and the drive gear 29 meshes with the arc-shaped rack 30. The transmission shaft 31 is rotatably connected inside the rotating seat 25, and the control console 32 is fixedly mounted on the side end of the transmission shaft 31. The other end of the transmission shaft 31 is fixedly connected to the outer wall of the drive gear 29. When the flat assembly drives the sliding frame 12, on which the rotating seat 25 is fixed, to rotate as a whole, the rotating seat 25 will rotate around the axis of the driven seat 8. Since the rotating seat 25 is connected to the drive gear 29 through the transmission shaft 31, the drive gear 29 will have a tendency to revolve. However, the drive gear 29 remains meshed with the arc-shaped rack 30 fixed on the connecting plate 26, and its roller 28 is constrained by the limiting groove 27 of the connecting plate 26. Under the constraint of the arc-shaped rack 30, the drive gear 29 is forced to rotate on its own axis while revolving around the axis. The rotation of the drive gear 29 is transmitted to the control console 32 via the transmission shaft 31, causing the control console 32 to rotate in the opposite direction and at the same angle as the bed board 9. This linkage design ultimately cancels out the influence of the bed board 9's rotation on the orientation of the control console 32, so that the control console 32 can automatically adjust and always maintain a horizontal posture, whether the bed board 9 is lying flat or standing and tilted, making it convenient for medical staff to operate.
[0040] The specific working process of this invention is as follows: When a gastrointestinal ultrasound contrast examination is required, the drive assembly of the basic mechanism is first activated: the first motor 4 drives the drive gear 5 to rotate, which in turn drives the driven gear 7 and the connecting shaft 6 fixed to it to rotate on the support column 2. The rotation of the connecting shaft 6 directly drives the driven seat 8 in the lying-flat assembly, which is fixed to its other end, to rotate synchronously, thereby causing the entire bed board 9 to flip. The patient can lie flat on the bed board 9. When the bed board 9 flips from a horizontal to a near-vertical standing position, the patient can step on the standing plate 24 of the standing assembly with both feet. During this process, the counterweight block 11 of the counterweight assembly provides counterweight in the counterweight groove 10 of the base 1 to balance the center of gravity and ensure the stability of the equipment. Subsequently, the installation mechanism is operated to precisely position the ultrasound probe: the second motor 13 of the sliding assembly is activated, driving the sprocket 14 and the transmission belt 15 to rotate, which in turn drives the sliding plate 17, which is fixed to the transmission belt 15, to move horizontally along the slide rail 16 in the length direction of the bed board 9; then the third motor 19 of the lifting assembly is activated, driving the lead screw 20 to rotate, which causes the lifting plate 21, which is threadedly connected to the lead screw 20, to rise and fall vertically; the lifting plate 21 drives the installation assembly at its bottom to move synchronously, thereby precisely adjusting the external ultrasound probe fixed on it to the patient's examination site. During the entire tilting process of the bed board 9, the tilting mechanism works synchronously to ensure that the control console 32 remains horizontal: the tilting of the bed board 9 causes the sliding frame 12 fixed on it and the rotating seat 25 of the transmission component to rotate together, forcing the drive gear 29, which meshes with the arc-shaped rack 30 fixed to the connecting plate 26, to revolve; the roller 28 of the drive gear 29 is restricted to slide within the limiting groove 27 of the connecting plate 26, and under the constraint of the arc-shaped rack 30, the drive gear 29 rotates on its own axis while revolving; the rotation of the drive gear 29 is transmitted to the control console 32 through the transmission shaft 31, causing it to generate a rotation equal in angle and opposite in direction to the tilting angle of the bed board 9, thereby automatically counteracting the influence of the bed board 9's posture change, ensuring that the operating interface of the control console 32 always remains horizontal, facilitating continuous operation by medical staff. After the inspection, each component runs in reverse, restoring the equipment to its initial state.
