When the telescopic cylinder is extended or retracted, the movable rod is driven to move, thereby changing the relative position between the leg support device and the bed board; Limb fixation device, the outer side of the limb fixation device is rotatably connected to the two sides of the bed board, the limb fixation device is located on the side of the leg support device close to the headrest, and the outer side of the rotating shell is rotatably connected to the two sides of the bed board, and the angle can be adjusted according to the position of the patient's limbs and examination requirements. This allows the limb fixation device to flexibly adapt to different patient positions and examination scenarios; The leg support device comprises a support block, the inner side of the support block is slidably connected to a sliding adjustment block, the outer side of the sliding adjustment block is rotatably connected to a rotating block, the top of the rotating block is fixedly connected to a limiting assembly, the outer side of the rotating block is fixedly connected to a locking assembly, the bottom of the support block is fixedly connected to an electric push rod, the tops of the support block and the sliding adjustment block are both fixedly connected to a pad, the thigh of the patient is placed on the pad, and then the calf of the patient is fixed by the limiting assembly to provide stable support for the leg; The limiting assembly includes an arc-shaped support block, an arc-shaped sleeve is fixedly connected to the inner side of the arc-shaped support block, an elastic clamp is slidably connected to the inner wall of the arc-shaped sleeve, a locking bolt is threadedly connected to the inner wall of the arc-shaped sleeve, an anti-falling component is fixedly connected to the outer side of the arc-shaped support block, and the bottom of the arc-shaped support block is fixedly connected to the top of the rotating block, providing a main support surface for the patient's legs; The anti-falling component includes a mounting plate, an elastic connecting plate is fixedly connected to the outer side of the mounting plate, a clamping plate is fixedly connected to the outer side of the elastic connecting plate, a clamping block is fixedly connected to the outer side of the clamping plate, and a limiting strip is fixedly connected to the bottom of the mounting plate.

[0005] Preferably, the top of the support block is rotatably connected to the bottom of the bed board, the bottom of the support block is rotatably connected to the end of the movable rod away from the telescopic cylinder, the outer side of the locking assembly is fixedly connected to the outer side of the sliding adjustment block, and the bottom of the sliding adjustment block is fixedly connected to the output end of the electric push rod. When the electric push rod works, it pushes the sliding adjustment block to slide in the support block, thereby changing the overall length of the leg support device. In this way, it can be ensured that the patient's legs can be completely placed on the leg support device.
[0006] Preferably, the bottom of the arc-shaped support block is fixedly connected to the top of the rotating block, the inner side of the elastic clamping plate is clamped with the outer side of the clamping block through a limiting hole, and the limiting hole is opened in the wall of the elastic clamping plate, and the elastic clamping plate is inserted into the mounting plate in the anti-falling component. At this time, the clamping block on the outer side of the clamping plate is clamped with the elastic clamping plate through the limiting hole to fix the patient's leg.
[0007] Preferably, the outer side of the mounting plate is fixedly connected to the outer side of the arc-shaped support block, and the outer side of the limit strip is in contact with the outer side of the clip-on plate. By setting the limit strip, the movable range of the clip-on plate is limited to prevent the clip-on plate from excessive deformation or displacement.
[0008] Preferably, the locking assembly includes a fixed sleeve, the inner side of which is slidably connected to a sliding plate, one side of which is fixedly connected to a compression spring, the other side of which is fixedly connected to a plug rod, the outer side of which is plugged with a porous plate through a plug hole, and the plug hole is opened in the wall of the porous plate. Under normal conditions, the compression spring is in a natural state and is not compressed. At this time, under the action of the compression spring, the sliding plate causes the plug rod to be inserted into a plug hole on the porous plate, thereby locking the position of the rotating block so that it cannot rotate at will.
[0009] Preferably, the inner side of the fixed sleeve is fixedly connected to the outer side of the rotating block, the inner wall of the fixed sleeve is fixedly connected to the outer side of the compression spring, and the outer side of the porous plate is fixedly connected to the outer wall of the sliding adjustment block. When the relative angle between the rotating block and the sliding adjustment block needs to be adjusted, the operator pulls the sliding plate and overcomes the elastic force of the compression spring to push the sliding plate to slide in the fixed sleeve, so that the insertion rod is pulled out of the current insertion hole. At this time, the rotating block can rotate relative to the sliding adjustment block.
[0010] Preferably, the limb fixing device comprises a rotating shell, the inner side of the rotating shell is fixedly connected with a rotating seat, the top of the rotating seat is rotatably connected with a placement plate, the inner side of the placement plate is fixedly connected with a rubber pad, the top of the placement plate is rotatably connected with a strap, a pneumatic telescopic rod is fixed on the side of the placement plate away from the strap, the top of the pneumatic telescopic rod is fixedly connected with a friction plate, the inner side of the placement plate is rotatably connected with a roller, the center of the rotating shell is fixedly connected with an elbow protection assembly, the outer side of the rotating shell is rotatably connected with both sides of the bed board, and the strap is passed between the roller and the friction plate. Subsequently, by operating the pneumatic telescopic rod, the friction plate is driven to move upward, and the strap is clamped between the roller and the friction plate. In this way, the arm or other limbs are fixed with a strap.
[0011] Preferably, the elbow protection assembly includes an oil storage shell, a piston rod is slidably connected to the inner side of the oil storage shell, a protection pad is fixedly connected to the top of the piston rod, a return spring is fixedly connected to the inner side of the oil storage shell, and an annular push plate is fixedly connected to the bottom end of the return spring. When the patient's elbow is placed on the protection pad, if the elbow applies pressure, the piston rod can slide in the oil storage shell. The hydraulic oil in the oil storage shell plays a buffering role to reduce the pressure on the elbow.
[0012] Preferably, the bottom of the oil storage shell is fixedly connected to the center of the rotating shell, a through hole is opened in the wall of the oil storage shell, the inner wall of the oil storage shell is slidably connected to the outer wall of the annular push plate, and when the piston rod is pressed down, the hydraulic oil pushes the annular push plate up through the through hole, and the return spring is compressed.
[0013] The beneficial effects of the present invention are as follows: 1. The present invention sets a telescopic cylinder. When the telescopic cylinder is extended or retracted, it will drive the movable rod to move, thereby changing the relative position between the leg support device and the bed board. When the telescopic cylinder is extended, the space for placing the legs can be adjusted according to the body shape and examination needs of different patients, making it convenient for patients to place their legs on the leg support device, and also convenient for doctors to perform examination operations. When the telescopic cylinder is shortened, the leg support device fits the bed board more closely, saving space and being convenient for storage when the leg support device is not in use.
[0014] 2. The present invention sets a leg support device, places the patient's thigh on the pad, and then the electric push rod works to push the sliding adjustment block to slide in the support block, thereby changing the overall length of the leg support device. This ensures that the patient's legs can be completely placed on the leg support device, avoiding the legs from being suspended or overstretched, thereby improving the patient's comfort and providing stable support for the legs. It helps to reduce the pressure on the legs and prevent the condition from being aggravated or causing pain due to improper support.
[0015] 3. The present invention provides a main support surface for the patient's legs by setting a limit assembly, and the bottom of the arc-shaped support block is fixedly connected to the top of the rotating block. Its arc-shaped design can better fit the shape of the patient's legs, increase the contact area of the legs, and improve the stability and comfort of the support.
[0016] 4. The present invention sets a limit assembly to pull the elastic clip out of the arc sleeve, and then inserts the elastic clip into the mounting plate in the anti-falling component. At this time, the clamping block on the outside of the clamping plate is clamped with the elastic clip through the limit hole to fix the patient's leg, thereby ensuring that the leg is always in a stable fixed state and preventing the elastic clip from being accidentally loosened during use.
[0017] 5. The present invention limits the range of movement of the snap-in plate by setting a limit bar, thereby preventing the snap-in plate from excessive deformation or displacement and ensuring the normal operation of the anti-falling component. When it is necessary to release the fixation, the snap-in plate is pulled to cause the elastic connecting plate to be deformed under force, and at the same time the card block is disengaged from the limit hole. At this time, the restriction on the elastic card plate can be quickly released. The operation process is simple and easy to use.
[0018] 6. The present invention sets a locking assembly, and under normal conditions, the compression spring is in a natural state and is not compressed. At this time, under the action of the compression spring, the sliding plate inserts the insertion rod into a hole on the porous plate, thereby locking the position of the rotating block so that it cannot rotate at will, ensuring that the patient's legs are placed stably on the medical bed, providing a reliable basis for subsequent medical operations such as ultrasound examinations.
[0019] 7. The present invention provides a locking assembly. When the relative angle between the rotating block and the sliding adjustment block needs to be adjusted, the operator pulls the sliding plate and overcomes the elastic force of the compression spring to push the sliding plate to slide in the fixed sleeve, so that the insertion rod is pulled out of the current insertion hole. At this time, the rotating block can be rotated relative to the sliding adjustment block to adjust to a position suitable for the bending angle of the patient's legs, ensuring that the patient's legs can be comfortably supported when using the leg support device, reducing discomfort and fatigue caused by inappropriate angles.
[0020] 8. The present invention provides a limb fixing device, and passes the strap between the roller and the friction plate. Then, the friction plate is driven to move upward by operating the pneumatic telescopic rod, and the strap is clamped between the roller and the friction plate. In this way, the arm or other limbs are fixed with the strap to ensure that the limb will not move during the examination. The strap can be adjusted according to the thickness of the limb to adapt to patients of different body shapes, thereby improving the fixation effect and reliability.
[0021] 9. The present invention provides a roller and a friction plate. When the strap passes between the roller and the friction plate, the groove on the roller surface can provide a certain positioning effect for the strap. The strap can be partially embedded in the groove. When the friction plate and the roller clamp the strap, the groove can prevent the strap from sliding on the roller surface, thereby enhancing the stability of the strap fixation and ensuring that the limb will not become loose due to the sliding of the strap after fixation.
[0022] 10. The present invention provides an elbow protection assembly. When the patient's elbow is placed on the protection pad, if the elbow exerts pressure, the piston rod can slide in the oil storage shell. The hydraulic oil in the oil storage shell acts as a buffer, reducing the pressure on the elbow and protecting the patient's elbow. When the piston rod is pressed down, the hydraulic oil pushes the annular push plate upward through the through hole, and the reset spring is compressed. Once the elbow pressure is reduced, the reset spring provides a downward elastic force to push the annular push plate, thereby resetting the piston rod, ensuring that the elbow protection assembly is always in a ready state and providing comfortable support and protection for the patient's elbow at any time.

When in use, the medical bed is mainly composed of support frame 1, moving wheel 2, bed board 3, headrest 4, leg support device 5, limb fixing device 6, telescopic cylinder 7 and movable rod 8. Support frame 1 can conveniently move the position of medical bed through moving wheel 2. Bed board 3 is used to support patient's body, and headrest 4 provides support for patient's head. The leg support device 5 is used to fix and adjust the position of the patient's legs, and the limb fixing device 6 is used to fix the patient's limbs.
[0027] When the telescopic cylinder 7 is extended or retracted, the movable rod 8 is driven to move, thereby changing the relative position between the leg support device 5 and the bed board 3. When the telescopic cylinder 7 is extended or retracted, the movable rod 8 is driven to move, so that the leg support devices 5 on both sides rotate around the connection point between them and the bed board 3, and the opening and closing angle becomes larger. In this way, the space for leg placement can be adjusted according to the body shape and examination needs of different patients, making it convenient for patients to place their legs on the leg support device 5, and also convenient for doctors to perform examination operations; when the telescopic cylinder 7 is shortened, the movable rod 8 is pulled to move, driving the leg support devices 5 on both sides to rotate around the connection point, and the opening and closing angle becomes smaller, so that the leg support devices 5 fit the bed board 3 more closely, saving space, and also convenient for storage when the leg support devices 5 are not in use; The leg support device 5 includes a support block 51, the inner side of the support block 51 is slidably connected to a sliding adjustment block 52, the outer side of the sliding adjustment block 52 is rotatably connected to a rotating block 53, the top of the rotating block 53 is fixedly connected to a limiting assembly 54, the outer side of the rotating block 53 is fixedly connected to a locking assembly 55, the bottom of the support block 51 is fixedly connected to an electric push rod 57, and the tops of the support block 51 and the sliding adjustment block 52 are both fixedly connected to a cushion block 56; when the leg support device 5 is in use, the thigh part of the patient is placed on the cushion block 56, and then the electric push rod 57 works to push the sliding adjustment block 52 to slide in the support block 51, thereby changing the overall length of the leg support device 5. This ensures that the patient's legs can be completely placed on the leg support device 5, avoiding the legs from being suspended or overstretched, thereby improving the patient's comfort and providing stable support for the legs. It helps to reduce the pressure on the legs and prevent aggravation of the condition or pain caused by inappropriate support. The limiting assembly 54 includes an arc-shaped support block 541, the inner side of the arc-shaped support block 541 is fixedly connected with an arc-shaped sleeve 542, the inner wall of the arc-shaped sleeve 542 is slidably connected with an elastic clamping plate 543, the inner wall of the arc-shaped sleeve 542 is threadedly connected with a locking bolt 544, and the outer side of the arc-shaped support block 541 is fixedly connected with an anti-falling component 546; the anti-falling component 546 includes a mounting plate 461, the outer side of the mounting plate 461 is fixedly connected with an elastic connecting plate 462, the outer side of the elastic connecting plate 462 is fixedly connected with a clamping plate 463, the outer side of the clamping plate 463 is fixedly connected with a clamping block 465, the bottom of the mounting plate 461 is fixedly connected with a limiting strip 464, the top of the support block 51 is rotatably connected to the bottom of the bed board 3, and the bottom of the support block 51 is remote from the movable rod 8 It is rotatably connected to one end of the telescopic cylinder 7, the outer side of the locking assembly 55 is fixedly connected to the outer side of the sliding adjustment block 52, the bottom of the sliding adjustment block 52 is fixedly connected to the output end of the electric push rod 57, the bottom of the arc support block 541 is fixedly connected to the top of the rotating block 53, the inner side of the elastic clamping plate 543 is clamped with the outer side of the clamping block 465 through the limiting hole 545, and the limiting hole 545 is opened in the wall of the elastic clamping plate 543, the outer side of the mounting plate 461 is fixedly connected to the outer side of the arc support block 541, the outer side of the limiting strip 464 is in contact with the outer side of the clamping plate 463, the patient's calf is fixed by the limiting assembly 54, the bottom of the arc support block 541 is fixedly connected to the top of the rotating block 53, providing a main support surface for the patient's leg. Its arc-shaped design can better fit the shape of the patient's legs, increase the contact area of the legs, and improve the stability and comfort of the support. The inner wall of the arc-shaped sleeve 542 is slidably connected with the elastic clamping plate 543. When the patient's legs are placed on the leg support device 5, the elastic clamping plate 543 is pulled out of the arc-shaped sleeve 542. At this time, the locking bolt 544 can prevent the elastic clamping plate 543 from being completely separated from the arc-shaped sleeve 542. Then, the elastic clamping plate 543 is inserted into the mounting plate 461 in the anti-falling component 546.

Then, by operating the pneumatic telescopic rod 66, the friction plate 67 is driven to move upward, and the strap 69 is clamped between the roller 68 and the friction plate 67. In this way, the arm or other limbs are fixed by the strap 69 to ensure that the limbs will not move during the examination. The strap 69 can be adjusted according to the thickness of the limbs to adapt to patients of different body shapes and improve the fixation effect and reliability; wherein, when the strap 69 passes between the roller 68 and the friction plate 67, the groove on the surface of the roller 68 can provide a certain positioning effect for the strap 69. The strap 69 can be partially embedded in the groove.

The hydraulic oil in the oil storage shell 621 acts as a buffer, reducing the pressure on the elbow and protecting the patient's elbow; when the piston rod 622 is pressed down, the hydraulic oil pushes the tube annular push plate 625 upward through the through hole 624, and the return spring 626 is compressed. Once the elbow pressure is reduced, the return spring 626 provides a downward elastic force to push the annular push plate 625, thereby returning the piston rod 622 to its original position, ensuring that the elbow protection assembly 62 is always in a ready state, providing comfortable support and protection for the patient's elbow at any time.
[0031] Working principle: When in use, the medical bed is mainly composed of a support frame 1, a moving wheel 2, a bed board 3, a headrest 4, a leg support device 5, a limb fixing device 6, a telescopic cylinder 7 and a movable rod 8. The support frame 1 can conveniently move the position of the medical bed through the moving wheel 2. The bed board 3 is used to support the patient's body, and the headrest 4 provides support for the patient's head. The leg support device 5 is used to fix and adjust the position of the patient's legs, and the limb fixing device 6 is used to fix the patient's limbs.
[0032] When the telescopic cylinder 7 is extended or retracted, the movable rod 8 is driven to move, thereby changing the relative position between the leg support device 5 and the bed board 3. When the telescopic cylinder 7 is extended or retracted, the movable rod 8 is pushed to move, so that the leg support devices 5 on both sides rotate around the connection points with the bed board 3, and the opening and closing angles become larger. In this way, the space for leg placement can be adjusted according to the body shape and examination requirements of different patients, making it convenient for patients to place their legs on the leg support device 5, and also convenient for doctors to perform examination operations; When the telescopic cylinder 7 is shortened, the movable rod 8 is pulled to move, driving the leg support devices 5 on both sides to rotate around the connection point, and the opening and closing angle becomes smaller, so that the leg support devices 5 are more closely fitted to the bed board 3, saving space and being convenient for storage when the leg support devices 5 are not in use.
[0033] When the leg support device 5 is in use, the patient's thigh is placed on the cushion block 56, and then the electric push rod 57 works to push the sliding adjustment block 52 to slide in the support block 51, thereby changing the overall length of the leg support device 5. This ensures that the patient's legs can be completely placed on the leg support device 5, avoiding the legs from being suspended or overstretched, thereby improving the patient's comfort and providing stable support for the legs. This helps to reduce the pressure on the legs and prevent the condition from being aggravated or causing pain due to improper support.
[0034] The patient's calf is then fixed by the stopper assembly 54, and the bottom of the arc-shaped support block 541 is fixedly connected to the top of the rotating block 53, providing a main support surface for the patient's leg. Its arc-shaped design can better fit the shape of the patient's leg, increase the contact area of the leg, and improve the stability and comfort of the support.
[0035] The inner wall of the arc sleeve 542 is slidably connected to the elastic clip plate 543. When the patient's legs are placed on the leg support device 5, the elastic clip plate 543 is pulled out of the arc sleeve 542. At this time, the locking bolt 544 can prevent the elastic clip plate 543 from being completely separated from the arc sleeve 542. Then the elastic clip plate 543 is inserted into the mounting plate 461 in the anti-falling component 546. At this time, the clamping block 465 on the outer side of the clamping plate 463 is clamped with the elastic clip plate 543 through the limiting hole 545 to fix the patient's legs, thereby ensuring that the legs are always in a stable fixed state and preventing the elastic clip plate 543 from being accidentally loosened during use.
[0036] Among them, by setting a limit strip 464 to limit the range of movement of the snap-in plate 463, the snap-in plate 463 is prevented from excessive deformation or displacement, thereby ensuring the normal operation of the anti-fall-off component 546. When it is necessary to release the fixation, the snap-in plate 463 is pulled to make the elastic connecting plate 462 deform under force, and at the same time the clamping block 465 is disengaged from the limit hole 545. At this time, the restriction on the elastic snap plate 543 can be quickly released. The operation process is simple and easy to use.
[0037] When the locking assembly 55 is in use, the inner side of the fixed sleeve 551 is fixedly connected to the outer side of the rotating block 53, providing a stable installation foundation and support structure for other components of the locking assembly 55. Under normal conditions, the compression spring 553 is in a natural state and is not compressed. At this time, under the action of the compression spring 553, the sliding plate 552 causes the insertion rod 554 to be inserted into a plug hole 556 on the porous plate 555, thereby locking the position of the rotating block 53 so that it cannot rotate at will, ensuring that the patient's legs are placed stably on the medical bed, and providing a reliable basis for subsequent medical operations such as ultrasound examinations.
[0038] When the relative angle between the rotating block 53 and the sliding adjustment block 52 needs to be adjusted, the operator pulls the sliding plate 552 and overcomes the elastic force of the compression spring 553, pushing the sliding plate 552 to slide in the fixed sleeve 551, so that the insertion rod 554 is pulled out from the current insertion hole 556. At this time, the rotating block 53 can be rotated relative to the sliding adjustment block 52 to adjust to a position suitable for the bending angle of the patient's legs, ensuring that the patient's legs can be comfortably supported when using the leg support device 5, reducing discomfort and fatigue caused by inappropriate angles. For some patients with leg injuries or diseases, a specific bending angle may be required to relieve pain or promote recovery. The deflectable characteristics of the rotating block 53 enable the medical bed to better meet the special needs of these patients and improve the patient's treatment experience and effect.
[0039] The outer side of the rotating shell 61 is rotatably connected to the two sides of the bed board 3, and the angle can be adjusted according to the position of the patient's limbs and the examination requirements. This allows the limb fixing device 6 to flexibly adapt to different patient positions and examination scenarios. The top of the rotating seat 63 is rotatably connected to the placement board 64, and the angle of the placement board 64 can be adjusted according to the placement requirements of different patient limbs. The inner side of the placement board 64 is fixedly connected with a rubber pad 65 to increase the friction between the patient's limbs and the placement board 64 to prevent the limbs from sliding on the placement board 64; The strap 69 is passed between the roller 68 and the friction plate 67. Then, the friction plate 67 is driven to move upward by operating the pneumatic telescopic rod 66, and the strap 69 is clamped between the roller 68 and the friction plate 67. In this way, the arm or other limbs are fixed by the strap 69 to ensure that the limbs will not move during the examination. The strap 69 can be adjusted according to the thickness of the limbs to adapt to patients of different body shapes, thereby improving the fixation effect and reliability.
[0040] When the strap 69 passes between the roller 68 and the friction plate 67, the groove on the surface of the roller 68 can provide a certain positioning effect for the strap 69. The strap 69 can be partially embedded in the groove, and when the friction plate 67 and the roller 68 clamp the strap 69, the groove can prevent the strap 69 from sliding on the surface of the roller 68, thereby enhancing the stability of the strap 69 fixation and ensuring that the limb will not become loose due to the sliding of the strap 69 after fixation.
[0041] When the elbow protection assembly 62 is in use, when the patient's elbow is placed on the protection pad 623, if the elbow exerts pressure, the piston rod 622 can slide in the oil storage shell 621. The hydraulic oil in the oil storage shell 621 acts as a buffer, reducing the pressure on the elbow and protecting the patient's elbow; When the piston rod 622 is pressed down, the hydraulic oil pushes the tube annular push plate 625 upward through the through hole 624, and the return spring 626 is compressed. Once the elbow pressure is reduced, the return spring 626 provides a downward elastic force to push the annular push plate 625, thereby returning the piston rod 622 to its original position, ensuring that the elbow protection assembly 62 is always in a ready state, providing comfortable support and protection for the patient's elbow at any time.
