Detailed Implementation

[0017] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0018] It should be understood that the terms “system,” “device,” “unit,” and / or “module” used herein are one way to distinguish different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0019] This specification provides a medical bed device through several embodiments. This medical bed device can be applied to various medical systems, such as radiographic imaging systems and radiotherapy systems. The following description primarily uses the application of the medical bed device in a radiotherapy system as an example. A radiotherapy system may include radiotherapy equipment and a medical bed device, wherein the radiotherapy equipment has a treatment space for performing radiological diagnosis or treatment on patients.

[0020] Figure 1 These are exemplary schematic diagrams of medical bed devices according to some embodiments of this specification. Figure 2 This is an exemplary schematic diagram showing the connection between the hook and the docking groove according to some embodiments of this specification. Figure 3 This is a partial structural schematic diagram of a movable bed board according to some embodiments of this specification.

[0021] In some embodiments, such as Figures 1-3 As shown, the medical bed device includes a treatment bed 10, a movable bed board 20, a conveying mechanism 30, and a docking assembly 40. The conveying mechanism 30 is detachably connected to the movable bed board 20 via the docking assembly 40, and the conveying mechanism 30 is slidably connected to the treatment bed 10. In some embodiments, the docking assembly 40 includes a hook 42 and a docking groove 43, a bracket 41 is disposed on the conveying mechanism 30, and the docking groove 43 is disposed on the movable bed board 20; the hook 42 rotates to dock with or disengage from the docking groove 43.

[0022] In some embodiments, the bracket 41 may also be disposed on the movable bed board 20, and the docking groove 43 may be disposed on the conveying mechanism 30.

[0023] The examination bed 10 is a bed used to accommodate a patient during examinations or treatments (such as radiotherapy, surgery, or examinations). In some embodiments, at least a portion of the examination bed 10 is located within an examination space, and the length of the examination bed 10 may depend on the axial length of the examination space. More information about examination spaces can be found in [link to relevant documentation]. Figure 6 And related explanations.

[0024] The movable bed board 20 is used to transfer patients. For example, the movable bed board 20 can transfer patients from wards, outpatient rooms, operating rooms, etc., to the space where the treatment bed 10 is located (such as a radiology room, operating room, examination room, etc.). In some embodiments, the movable bed board 20 is made of high-strength lightweight materials (such as high-density fiberboard, aluminum alloy, etc.), and has sufficient strength and stability to ensure patient safety.

[0025] The conveying mechanism 30 is used to convey the movable bed board 20 onto the examination bed 10. In some embodiments, the conveying mechanism 30 is slidably connected to the examination bed 10, and the conveying mechanism 30 can slide along the length of the examination bed 10. For example, Figure 1 As shown, the conveying mechanism 30 can slide along the X-axis.

[0026] In some embodiments, the conveying mechanism 30 and the treatment bed 10 can be made slidable in various ways. For example, the conveying mechanism 30 can be provided with a slider, a roller or a gear, and the treatment bed 10 can be provided with a slide rail that matches the slider, a guide rail that matches the roller or a rack structure that matches the gear, thereby enabling the conveying mechanism 30 to slide on the treatment bed 10.

[0027] In some embodiments, the conveying mechanism 30 conveys the movable bed board 20 to a specific position on the treatment bed 10, which can be determined based on various factors such as the specific application scenario of the medical bed equipment, the type of treatment operation required by the patient, the area to be treated, and the patient's body type. For example, when the medical bed equipment is used in a radiotherapy system, the conveying mechanism 30 can convey the movable bed board 20 to the imaging area of ​​the radiotherapy equipment in the radiotherapy system. In some embodiments, the operator (such as a doctor) can adjust the specific position of the movable bed board 20 conveyed by the conveying mechanism 30 onto the treatment bed 10. For more information on radiotherapy systems, please refer to [link to relevant documentation]. Figure 6 Related explanations.

[0028] The docking assembly 40 is used to dock or detach the moving bed board 20 from the conveying mechanism 30.

[0029] Hook 42 is used to connect docking assembly 40 to movable bed board 20.

[0030] The number of hooks 42 can be set according to requirements. For example, such as Figure 2 As shown, the docking component 40 includes two hooks 42.

[0031] In some embodiments, the docking assembly 40 further includes a bracket 41 for supporting the hook 42. In some embodiments, such as... Figure 2 As shown, when the hook 42 is rotatably mounted on the conveying mechanism 30, the bracket 41 is fixed to the conveying mechanism 30. For example, the bracket 41 can be fixed to the conveying mechanism 30 by a locking nut. Alternatively, the bracket 41 and the conveying mechanism 30 can be integrally formed. In some embodiments, when the hook 42 is rotatably mounted on the movable bed board 20, the bracket 41 is fixed to the movable bed board 20.

[0032] In some embodiments, the hook 42 may include a connecting rod and a hook-shaped portion, the connecting rod being rotatably connected to the bracket 41. The hook-shaped portion is a curved hook-shaped structure that engages with the mating groove 43 to maintain a stable connection with the mating groove 43.

[0033] The mating groove 43 is a recess provided on the movable bed board 10. In some embodiments, the number of mating grooves 43 is the same as the number of hooks 42. Each mating groove 43 corresponds one-to-one with a hook 42. For example, as shown... Figure 2 As shown, when the docking assembly 40 includes two hooks 42 and two docking slots 43, the two hooks 42 and the two docking slots 43 correspond one-to-one. In other embodiments, the number of docking slots 43 may be greater than the number of hooks 42.

[0034] Figure 4 This is an exemplary schematic diagram showing the hook disengaging from the docking groove according to some embodiments of this specification. Figure 5This is an exemplary schematic diagram showing the movable bed board detached from the conveying mechanism according to some embodiments of this specification. The following is in conjunction with... Figure 2 and Figures 4-5 Please provide an explanation.

[0035] In some embodiments, by rotating the hook 42, the hook 42 can be engaged or disengaged from the docking groove 43, thereby enabling the conveying mechanism 30 to engage or disengage from the movable bed board 20. Before the surgery begins, such as... Figure 2 As shown, the patient is placed on the movable bed board 20. After the conveying mechanism 30 moves into position (e.g., the first sensor 46 detects that the movable bed board 20 has reached a position where docking assembly 40 can dock), the hook 42 is rotated to lift it up (e.g., along...). Figure 2 Rotate hook 42 in direction b), then rotate hook 42 again to lower it (for example, along...). Figure 2 Rotate hook 42 in direction a until it aligns with docking slot 43, thus connecting the conveying mechanism 30 with the movable bed board 20. This allows the conveying mechanism 30 to move the movable bed board 20 to the treatment bed 10, thereby transferring the patient onto the treatment bed 10. After the surgery, if... Figure 4 As shown, the moving conveyor mechanism 30 drives the moving bed board 20 to move away from the treatment bed 10, and the rotating hook 42 lifts it up (for example, along...). Figure 2 and Figure 4 Rotate hook 42 in direction b until it disengages from docking groove 43, control the moving bed plate 20 away from conveying mechanism 30 (manual dragging or conveying via moving bed body 60 as described below), so that moving bed plate 20 disengages from conveying mechanism 30 (e.g., ...). Figure 5 (As shown).

[0036] Some embodiments of this specification include, but are not limited to, the following beneficial effects: (1) The medical bed equipment, through the coordinated work of the treatment bed 10, the movable bed board 20, and the conveying mechanism 30, enables convenient and safe patient transfer. It also reduces the burden of manual handling and improves treatment efficiency. (2) The design of the docking component 40 ensures a firm connection between the movable bed board 20 and the conveying mechanism 30, thereby guaranteeing the stability and safety of the entire transfer process. The hook 42 allows for quick docking and disengagement between the movable bed board 20 and the conveying mechanism 30, improving conveying efficiency.

[0037] In some embodiments, such as Figure 1As shown, the medical bed device also includes a movable bed body 60, on which a movable bed board 20 is detachably mounted. The movable bed body 60 supports the movable bed board 20. The movable bed board 20 being detachably mounted on the movable bed body 60 can be understood as follows: the movable bed board 20 is mounted on the movable bed body 60, but it can be removed from the movable bed body 60. For example, the movable bed board 20 can be detachably connected to the movable bed body 60. Alternatively, the movable bed board 20 can be placed directly on the movable bed body 60 (the two may not be connected). When the movable bed board 20 is placed on the movable bed body 60, it can be removed from the movable bed body 60 in one or more directions (e.g., lifting the movable bed board 20 upwards removes it from the movable bed body 60). In some embodiments, the movable bed body 60 is height-adjustable (e.g., along...). Figures 1-6 The Z-axis direction is raised and lowered, thereby driving the movable bed board 20 to rise and fall.

[0038] The lifting and lowering of the movable bed 60 facilitates patient access to and from the bed. Furthermore, by enabling the movable bed 60 to be raised and lowered, the height of the movable bed board 20 can be adjusted to change with the height of the treatment bed 10, thereby better facilitating the connection between the movable bed board 20 and the conveying mechanism 30, and ultimately transporting the movable bed board 20 onto the treatment bed 10.

[0039] In some embodiments, the examination bed 10 can be raised or lowered (e.g., along the [path]). Figure 1 The movable bed board 20 is located on the treatment bed 10 and can rise and fall with the treatment bed 10. The rising and falling of the treatment bed 10 makes the diagnosis and treatment operation more convenient.

[0040] In some embodiments, the examination bed 10 and the movable bed 60 can be height-adjustable in various ways. For example, a bed frame and a lifting base may be included below the examination bed 10 and on the movable bed 60. The lifting base can raise and lower the bed frame of the examination bed 10 and / or the movable bed 20 to adjust the height of the bed frame of the examination bed 10 and / or the movable bed 20 from the ground, thereby facilitating patient transfer. For example, as... Figure 1 As shown, bases 71 and drive devices 72 are provided below both ends of the treatment bed 10. The drive devices 72 are mounted on the bases 71 and connected to the bed frame of the treatment bed 10, and control the raising and lowering of the bed frame of the treatment bed 10. The drive devices 72 may include motors (such as linear motors), hydraulic cylinders, pneumatic cylinders, etc. Similar devices to the bases 71 and drive devices 72 may be provided on the movable bed body 60.

[0041] In some embodiments, when the movable bed board 20 is located on the movable bed body 60, the relative position of the conveying mechanism 30 and the movable bed board 20 can be changed by lowering the movable bed body 60 or raising the treatment bed 10, thereby disengaging the hook 42 from the docking groove 43. When the movable bed board 20 moves to a position close to the conveying mechanism 30, the height of the treatment bed 10 can be raised or the height of the movable bed body 60 can be lowered so that the movable bed board 20 is located below the hook 42, and the position of the movable bed body 60 can be adjusted so that the projection of the hook 42 coincides with the docking groove 43. Then, the height of the treatment bed 10 can be lowered or the movable bed body 60 can be raised to dock the hook 42 with the docking groove 43.

[0042] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the docking assembly 40 also includes an elastic element 44 and an unlocking element 45. The hook 42 is disposed on the unlocking element 45, and the elastic element 44 is disposed between the conveying mechanism 30 and the unlocking element 45.

[0043] The elastic element 44 provides an elastic restoring force to the hook 42. The elastic element 44 can be a coil spring, torsion spring, rubber pad, etc. Under the action of the elastic restoring force, the elastic element 44 keeps the hook 42 engaged with the mating groove 43. In some embodiments, when the hook 42 is engaged with the mating groove 43, the elastic element 44 is in a state of elastic deformation, thereby providing an elastic restoring force to keep the hook 42 engaged with the mating groove 43.

[0044] The unlocking element 45 is used to control the rotation state of the hook 42. In some embodiments, the unlocking element 45 can be manually or automatically controlled to cause the hook 42 to rotate relative to the bracket 41. In some embodiments, the unlocking element 45 includes an unlocking handle 451 and a pressure plate 452. The rotation of the hook 42 relative to the bracket 41 can be easily controlled by controlling the unlocking handle 451. The pressure plate 452 is used to connect the unlocking handle 451 and the hook 42. In some embodiments, the pressure plate 452 is disposed above the hook, and the unlocking handle 451 is detachably connected to the pressure plate 452. An elastic element 44 is disposed between the pressure plate 452 and the conveying mechanism 30.

[0045] In some embodiments, the unlocking handle 451 can be pushed or pulled manually or by the drive mechanism 50, which can cause the pressure plate 452 to drive the hook 42 to rotate relative to the bracket 41.

[0046] In some embodiments, a hook pivot 48 is provided on the bracket 41. The hook 42 can rotate about the hook pivot 48. In some embodiments, such as Figure 2 As shown, taking the docking assembly 40 as an example, which includes two hooks 42, both hooks 42 are rotatably mounted on the hook shaft 48.

[0047] In some embodiments, the hook 42 and the elastic element 44 are located on opposite sides of the hook shaft 48 along the conveying direction of the conveying mechanism 30. When the hook 42 is lifted or in a docking state, the elastic element 44 is compressed and deformed to generate an elastic restoring force, and the hook 42 automatically falls down under the action of the elastic restoring force and docks with the docking groove 43. The conveying direction of the conveying mechanism 30 refers to the direction of movement of the conveying mechanism 30 when conveying the movable bed board 20. For example, as shown... Figure 1 and Figure 2 As shown, the conveying direction can be the X-axis direction.

[0048] In other embodiments, the hook 42 and the hook shaft 48 are along the conveying direction of the conveying mechanism 30 (e.g., Figures 1-2 The hooks (in the X-axis direction) are located on both sides of the elastic element 44. When the hook 42 is lifted or in the docking state, the elastic element 44 is stretched and deformed to generate elastic restoring force. The hook 42 can automatically fall down under the action of elastic restoring force and maintain docking with the docking groove 43.

[0049] In some embodiments of this specification, by setting the elastic element 44 and the unlocking element 45, the hook 42 can be automatically reset and docked with the docking groove 43, and the hook 42 and the docking groove 43 can always be tightly docked to avoid separation due to external force or vibration, thereby achieving the effects of stability, automatic reset and convenient unlocking.

[0050] In some embodiments, the conveyor mechanism 30 and the movable bed 20 can be manually docked or detached. Figure 2 Taking the illustrated embodiment as an example, before the surgery begins, after the conveying mechanism 30 moves into position near the movable bed board 20, the unlocking handle 451 is manually pressed, causing the hook 42 to lift. Releasing the unlocking handle 451 allows the hook 42 to fall under the influence of gravity or the elastic restoring force of the elastic element 44, thus engaging with the docking groove 43. Furthermore, the hook 42 maintains a more stable engagement with the docking groove 43 under the elastic restoring force of the elastic element 44. For another example, after the surgery, the conveying mechanism 30 can convey the movable bed board 20 to one end of the treatment bed 10. The unlocking handle 451 is then manually pressed, causing the hook 42 to lift and disengage from the docking groove 43.

[0051] In some embodiments, such as Figures 1-2 As shown, the medical bed device also includes a drive mechanism 50, which drives the hook 42 to rotate. The drive mechanism 50 includes a drive line 51 and a reel 52. The reel 52 is located on the treatment bed 10 at one end away from the docking position between the conveying mechanism 30 and the movable bed board 20. The drive line 51 connects the reel 52 and the unlocking member 45.

[0052] The drive mechanism 50 is used to drive the hook 42 to rotate, thereby enabling the hook 42 to engage or disengage from the docking groove 43.

[0053] The drive line 51 is used to transmit the power generated by the rotation of the reel 52 to the unlocking member 45. In some embodiments, the drive line 51 is made of a high-strength, wear-resistant material, such as steel wire rope or synthetic fiber rope.

[0054] The reel 52 is used to wind or unwind the drive cable 51 by means of rotation. The reel 52 can be driven by a motor or a manual crank. The drive cable 51 can be wound onto the reel 52.

[0055] In some embodiments, one end of the drive cable 51 is fixed to the reel 52, and the other end is connected to the unlocking member 45. When the reel 52 rotates, the drive cable 51 is wound up or unwound, causing the hook 42 to rotate via the unlocking member 45.

[0056] Some embodiments in this specification, through the setting of drive line 51 and reel 52, achieve automated control of the rotation of hook 42, reducing manual operation and improving the operating efficiency and convenience of the equipment. The reel is located at the end of the treatment bed away from the docking position between the conveying mechanism 30 and the moving bed board 20, making reasonable use of the space layout of the treatment bed 10, avoiding interference with other functional components, and improving the overall compactness and aesthetics of the equipment.

[0057] In other embodiments, the drive mechanism 50 may also include a linear motor, hydraulic push rod, etc., mounted on the conveying mechanism 30 to push or pull the unlocking member 45.

[0058] In some embodiments, such as Figure 2 As shown, the drive mechanism 50 also includes a cable guide mechanism 53, which is mounted on the conveying mechanism 30 and guides the drive line 51.

[0059] The cable guide mechanism 53 is used to guide the drive cable 51 and restrict its movement, preventing the drive cable 51 from affecting the operation of the medical bed device due to bending or deviation. In some embodiments, the cable guide mechanism 53 can be a roller or an annular structure with an annular groove. The drive cable 51 is wound around the roller or within the annular groove of the annular structure.

[0060] In some embodiments of this specification, the distance between the reel 52 and the hook 42 may be relatively far in certain situations. By setting the cable guide mechanism 53, it can be ensured that the drive line 51 can stably transmit the power generated by the rotation of the reel 52 to the unlocking member 45 under various conditions.

[0061] In some embodiments, the conveying mechanism 30 and the movable bed board 20 can be actively docked or disengaged via the docking assembly 40. For example, before surgery, the conveying mechanism 30 moves toward the movable bed board 20, and the reel 52 releases a corresponding length of wire as the conveying mechanism 30 moves. After the conveying mechanism 30 reaches its position (e.g., the first sensor 46 detects that the movable bed board 20 has reached a position where docking can be achieved), the reel 52 winds up the drive wire 51, thereby pulling the unlocking handle 451, causing the hook 52 to lift up. The conveying mechanism 30 continues to move closer to the movable bed board 20, and the reel 52 releases the drive wire 51, causing the hook 42 to fall down and dock with the docking groove 43 on the movable bed board 20. As another example, after surgery, the conveying mechanism 30 can convey the movable bed board 20 to one end of the treatment bed 10. The reel 52 winds up the drive wire 51, thereby pulling the unlocking handle 451, causing the hook 52 to lift up and disengage from the docking groove 43.

[0062] In some embodiments, such as Figure 3 and Figure 5 As shown, the hook 42 is provided with a first guide slope 421, and the movable bed board 20 is provided with a guide member 21. The guide member 21 and the docking groove 43 are arranged along the conveying direction of the conveying mechanism 30; the guide member 21 cooperates with the first guide slope 421.

[0063] The first guide ramp 421 is a ramp located at the lower part of the hook 42 near the movable bed board 20. The first guide ramp 421 has an acute or obtuse angle with the treatment bed board or movable bed board 20 of the treatment bed 10.

[0064] The guide member 21 is a component that guides the hook 42 into the docking groove 43 by cooperating with the first guide ramp 421, thereby guiding the hook 42 to rotate as it moves toward the moving bed board 20 with the conveying mechanism 30.

[0065] In some embodiments, the first guide slope 421 is provided in a one-to-one correspondence with the guide member 21, and the guide member 21 is provided in a one-to-one correspondence with the hook 42.

[0066] For more information on the conveying direction, please refer to [link / reference]. Figures 1-3 Related explanations.

[0067] The contact between the first guide ramp 421 and the guide member 21 guides the hook 42 to move, thereby ensuring that the hook 42 can be correctly aligned with or engaged in the docking groove 43 during movement. Another solution to achieve the lifting of the hook 42 ensures that the hook 42 can be lifted stably.

[0068] In some embodiments, the guide member 21 includes a second guide ramp 211. The second guide ramp 211 is a ramp on the movable bed board 20 used to guide the movement of the hook 42. The second guide ramp 211 may at least partially abut against the first guide ramp 421, and the inclination direction and inclination angle of the second guide ramp 211 are consistent with those of the first guide ramp 421.

[0069] In some embodiments, the guide member 21 includes a guide wheel 212. The guide wheel 212 is a rolling component located at the edge of the movable bed board 20. When the movable bed board 20 approaches the conveying mechanism 30, the guide wheel 212 contacts the first guide ramp 421 of the hook 42, causing the guide wheel 212 to roll, thereby rotating the hook 42 and guiding the movement direction of the first guide ramp 421.

[0070] In some embodiments, the guide member 21 includes a second guide ramp 211 and a guide wheel 212, the second guide ramp 211 and the guide wheel 212 being arranged along the conveying direction of the conveying mechanism 30. For example, Figure 3 As shown, the second guide ramp 211 and guide wheel 212 are arranged along the X-axis. The guide wheel 212 can prevent the hook 42 from getting stuck or deviating during movement, and the second guide ramp 211 can help the hook 42 adjust its position before entering the docking groove 43, improving the accuracy of guidance. The cooperation of the second guide ramp 211 and guide wheel 212 can better guide the hook 42 to dock with the docking groove 43, achieving more efficient, stable and reliable object transportation.

[0071] In some embodiments of this specification, the guide wheel 212 and / or the second guide ramp 211 cooperate with the first guide ramp 421 on the hook to guide the rotation or adjust the position of the hook 42, thereby achieving precise docking with the movable bed board 20. At the same time, the design of the guide wheel 212 can reduce friction between the hook 42 and the movable bed board 20, extending the service life of the equipment.

[0072] In some embodiments, the conveying mechanism 30 and the moving bed 20 can be passively docked or disengaged via the docking assembly 40. Figure 4 In the illustrated embodiment, before the surgery begins, as the conveying mechanism 30 moves towards the movable bed board 20, the first guide slope 421 of the hook 42 contacts the guide wheel 212 at the edge of the movable bed board 20, forcing the hook 42 to rise. Simultaneously, the conveying mechanism 30 continues to approach the movable bed board 20, and the hook 42 slides along the second guide slope 211 on the movable bed board 20 until it reaches the docking groove 43. Under the influence of gravity and the elastic restoring force of the elastic element 44, the hook 42 remains docked with the docking groove 43. Alternatively, at the end of the surgery, when the movable bed board 20 is completely detached from the treatment bed 10, the height of the treatment bed 10 is raised or the height of the movable bed 60 is lowered, causing the hook 42 to disengage from the docking groove 43.

[0073] In some embodiments, such as Figure 2 As shown, the docking assembly includes a first sensor 46, which is used to detect whether the moving bed board 20 and the conveying mechanism 30 have reached a position where the docking assembly 40 can dock. In some embodiments, such as Figure 2 As shown, the docking assembly 40 includes a second sensor 47, which is used to detect whether the hook 42 is in the state of docking with the docking groove 43.

[0074] In some embodiments, the first sensor 46 and the second sensor 47 are fiber optic sensors. Fiber optic sensors are less susceptible to environmental influences when used in specific medical scenarios (such as radiotherapy scenarios).

[0075] In some embodiments, the first sensor 46 includes a emitting component and a receiving component. The emitting component of the first sensor 46 can emit light (such as a laser). The receiving component can receive reflected light. The first sensor 46 can determine whether the moving bed board 20 and the conveying mechanism 30 have reached the position where the docking assembly 40 can dock, based on the light reception status of the receiving component (such as whether reflected light is received, the intensity of the reflected light, etc.). The second sensor 47 is similar to the first sensor 46. In some embodiments, the second sensor 47 can determine whether the hook 42 is docked with the docking groove 43 based on the received light reflected from the emitting component.

[0076] In some embodiments, the first sensor 46 and the second sensor 47 may also be infrared sensors, contact switches, etc.

[0077] In some embodiments, when the first sensor 46 detects that the moving bed board 20 and the conveying mechanism 30 have reached the position where the docking assembly 40 can dock, and the second sensor 47 detects that the hook 42 is in the state of docking with the docking groove 43 (i.e., the hook 42 is in the state of being lowered), the conveying mechanism 30 is then controlled to convey the moving bed board 20 to ensure safety.

[0078] In some embodiments of this specification, the position of the movable bed board 20 and the state of the hook 42 can be detected and fed back through the first sensor 46 and the second sensor 47, thereby improving the accuracy of docking and ensuring patient safety.

[0079] In some embodiments, such as Figure 1 As shown, the medical bed equipment includes a belt drive mechanism 11 mounted on the treatment bed 10. The conveying mechanism 30 moves on the treatment bed 10 via the belt drive mechanism 11, thereby conveying the movable bed board 20. The drive belt of the belt drive mechanism 11 moves synchronously with the drive line 51.

[0080] The drive belt of the belt drive mechanism 11 runs along the length of the treatment bed 10 (e.g., Figure 1 The X-axis direction is set in the middle. The belt drive mechanism 11 can transmit power through the friction of the drive belt, thereby driving the conveying mechanism 30 to move along the drive belt, and then conveying the moving bed board 20 to the treatment bed 10.

[0081] In some embodiments, the medical bed device includes a chain drive mechanism 12 disposed on the treatment bed 10. The conveying mechanism 30 moves on the treatment bed 10 via the chain drive mechanism 12, thereby conveying the movable bed board 20. The drive chain of the chain drive mechanism 12 moves synchronously with the drive line 51.

[0082] The transmission chain of the chain drive mechanism 12 is along the length of the treatment bed 10 (e.g., Figure 1 The X-axis direction is set in the middle. The chain drive mechanism 12 can transmit power through the rigid connection between the drive chain and the sprocket, thereby driving the conveying mechanism 30 to move along the drive belt, and then conveying the moving bed board 20 to the treatment bed 10.

[0083] When the transmission belt or transmission chain drives the conveyor mechanism 30 to move, the drive line 51 moves synchronously with the transmission belt or transmission chain.

[0084] In some implementations of this specification, by setting up a belt drive mechanism 11 or a chain drive mechanism 12, the synchronous movement of the drive belt or chain with the drive line 51 can prevent the drive line 51 from bending or slipping during the conveying of the moving bed board 20 by the conveying mechanism 30, and the drive line 51 will not accidentally drive the unlocking member 45, causing the hook 42 to disengage from the docking groove 43.

[0085] Radiological diagnostic and treatment equipment is medical equipment that uses radioactive materials or radiation to diagnose and treat diseases. Examples of radiological diagnostic and treatment equipment include CT scanners, linear accelerators, and magnetic resonance imaging (MRI) devices.

[0086] A treatment space is the area within a radiology diagnostic and treatment facility used to house patients and conduct radiological treatments. Examples include the scanning chamber of a CT scanner and the treatment room of a radiotherapy unit.

[0087] Some embodiments of this specification provide a radiological diagnostic and treatment system. Figure 6 These are exemplary structural diagrams of a radiological diagnostic and treatment system according to some embodiments of this specification. In some embodiments, such as Figure 6 As shown, the radiotherapy system 200 includes a radiotherapy device 210 and a medical bed device 220. The radiotherapy device 210 includes a treatment space 201, and at least a portion of the treatment bed 10 of the medical bed device 220 is located within the treatment space 201.

[0088] The treatment space 201 is a ring-shaped space surrounding the patient. The axial direction of the treatment space 201 can be... Figure 6 The X-axis direction is shown.

[0089] In some embodiments, such as Figure 6 As shown, the medical bed device 220 includes a treatment bed 10, a movable bed board 20, a conveying mechanism 30, and a movable bed body 60. More information about medical bed devices can be found at [link to relevant documentation]. Figures 1-5 And related instructions. The radiotherapy system 200, by using the medical bed device 220, allows for more convenient and safer transport of patients requiring radiotherapy procedures.

[0090] Radiodiagnostic equipment is medical equipment that uses radioactive materials or radiation to diagnose and treat diseases.

[0091] In some embodiments, the radiotherapy device 210 may include an imaging device. In some embodiments, the radiotherapy device 210 may include a treatment device. In some embodiments, the radiotherapy device 210 may include both an imaging device and a treatment device, such that the radiotherapy device 210 has both radiographic imaging and radiotherapy functions, and that radiotherapy can be performed under the image guidance of radiographic imaging. In some embodiments, the isocenters of the imaging device and the treatment device coincide. The isocenter of the imaging device and the treatment device is the point around which the accelerator rotates during radiographic imaging and treatment. By setting the isocenters of the imaging device and the treatment device to coincide, the accuracy of image guidance during radiotherapy can be ensured.

[0092] In some embodiments, the imaging equipment of the radiotherapy device 210 may include magnetic resonance imaging (MR) equipment, positron emission tomography (PET) equipment, positron emission tomography-computed tomography (PETCT) equipment, X-ray imaging (XR) equipment, computed tomography (CT) equipment, single-photon emission computed tomography (SPECT) equipment, ultrasound equipment, etc. The treatment equipment of the radiotherapy device 210 may include radiotherapy equipment (RT equipment), etc.

[0093] In some embodiments, the radiotherapy device 210 may include one or more of the imaging devices and treatment devices described above. For example, when multiple radiotherapy devices 210 all need to scan and detect patients, the axial length of the treatment space 201 will also be relatively longer (which can be regarded as the sum of the axial lengths of the treatment space 201 corresponding to each radiotherapy device 210).

[0094] In some embodiments of this specification, the radiotherapy system, by integrating radiotherapy equipment and medical bed equipment, can provide an efficient, safe, and accurate treatment environment, suitable for various radiotherapy scenarios, such as tumor radiotherapy and imaging diagnosis.
