Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multifunctional bed frame. Background Technology

[0002] In the medical field, especially during radiotherapy, the stability of the patient's position is crucial for the smooth progress of radiotherapy and the patient's safety. The patient's position is mainly fixed by using a treatment bed to fix the head and ankle, with the head placed on a head pillow and the ankle placed on an ankle pillow. However, the head pillow and ankle pillow need to be adjusted adaptively for different patients. But the existing treatment bed requires the head pillow and ankle pillow to be adjusted separately during the adjustment process, which is complicated.

[0003] Therefore, there is an urgent need for a multifunctional bed frame to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional bed frame that can not only meet the treatment needs of different patients, but is also easy to operate.

[0012] As a preferred embodiment of a multifunctional bed frame, the drive assembly further includes a drive member, and the second transmission member includes a rotating part and a transmission part. The first end of the rotating part is rotatably connected to the bed board, and the second end of the rotating part is threadedly connected to the transmission part. The end of the transmission part opposite to the rotating part is slidably inserted into the opening of the second cylinder. The drive member is used to drive the rotating part to rotate so that the transmission part moves relative to the second cylinder in the first direction.

[0013] As a preferred embodiment of a multifunctional bed frame, the bed board has a first through hole and a second through hole, the head assembly is movably inserted through the first through hole, and the ankle assembly is movably inserted through the second through hole.

The top of the first storage box has a first opening communicating with the first through hole, and the bottom of the first storage box has a first through hole. The headrest passes through the first through hole and is connected to the first transmission member below the first storage box. The headrest can move through the first opening in the first direction.

[0015] As a preferred embodiment of a multifunctional bed frame, the head support includes a first support column and a second support column rotatably connected to the headrest. The end of the first support column not connected to the headrest is connected to the first transmission component, and the end of the second support column not connected to the headrest is rotatably connected to the first support column. The length of the second support column along its own axial direction is adjustable.

[0016] As a preferred embodiment of a multifunctional bed frame, a second storage box is provided at the second through hole. The top of the second storage box has a second opening communicating with the second through hole, and the bottom of the second storage box has a second through hole. The ankle support passes through the second through hole and is connected to the third transmission member below the second storage box. The ankle pillow can move through the second opening in the first direction.

[0017] As a preferred embodiment of the multifunctional bed frame, the multifunctional bed frame further includes two clamping components, which are disposed opposite to each other above the bed board along a second direction. The two clamping components are movable relative to the bed board along the second direction, and the clamping components are used to abut against the patient's upper limbs.

The headrest assembly includes a rotatably connected head support and a head pillow. The head support drives the head pillow to rotate, and the head pillow supports and secures the patient's head. The ankle support assembly includes a connected ankle support and an ankle pillow. The ankle pillow supports and secures the patient's ankles. By using the drive assembly to drive the bed board, headrest assembly, and ankle support assembly, the head pillow and ankle pillow can be positioned above or below the bed board in the first direction. When it is necessary to support the patient's head and ankles, the drive assembly can drive the bed board to move downwards in the first direction (vertical direction). Simultaneously, the head pillow and ankle pillow will move upwards in the first direction (vertical direction), so that the head pillow and ankle pillow are positioned above the bed board. When the patient lies on the bed board, the corresponding body parts can be placed on the head pillow or ankle pillow for fixation. The head support can also drive the head pillow to rotate to meet the patient's positional needs in different situations. When it is not necessary to support and fix the patient's head and ankles, the bed board can be driven upwards in the first direction, i.e., the vertical direction, using a drive assembly. Simultaneously, the headrest and ankle pillow will move downwards in the first direction, i.e., the vertical direction, so that the headrest and ankle pillow are located below the bed board, thus achieving storage of the headrest and ankle pillow. At this time, the bed board can also be used as a regular bed. In addition, the multifunctional bed frame proposed in this invention uses a drive assembly to achieve synchronous adjustment of the head support, ankle support, and bed board, making operation convenient.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figures 1 to 7As shown, this embodiment provides a multifunctional bed frame, including a bed body 3, a head assembly 1, and an ankle assembly 2. The bed body 3 includes a bed board 38 and a drive assembly. The drive assembly drives the bed board 38 to move in a first direction, and simultaneously drives the head assembly 1 and the ankle assembly 2 to move in the opposite direction to the bed board 38 in the first direction. The head assembly 1 includes a rotatably connected head support 11 and a head pillow 12. The head support 11 drives the head pillow 12 to rotate, and the head pillow 12 supports and fixes the patient's head. The ankle assembly 2 includes a connected ankle support 21 and an ankle pillow 22. The ankle pillow 22 supports and fixes the patient's ankle. By using the drive assembly to drive the bed board 38, the head assembly 1, and the ankle assembly 2, the head pillow 12 and the ankle pillow 22 can be positioned above or below the bed board 38 in the first direction. In practice, if support and fixation of the patient's head and ankles are required, the drive assembly can be used to drive the bed board 38 downward in the first direction, i.e., the vertical direction. Simultaneously, the head pillow 12 and ankle pillow 22 will move upward in the first direction, i.e., the vertical direction, so that the head pillow 12 and ankle pillow 22 are above the bed board 38. When the patient lies on the bed board 38, the corresponding body parts can be placed on the head pillow 12 or ankle pillow 22. The head support 11 can also drive the head pillow 12 to rotate to meet the patient's positional needs in different situations. When support and fixation of the patient's head and ankles are not required, the drive assembly can be used to drive the bed board 38 upward in the first direction, i.e., the vertical direction. Simultaneously, the head pillow 12 and ankle pillow 22 will move downward in the first direction, i.e., the vertical direction, so that the head pillow 12 and ankle pillow 22 are below the bed board 38, thus achieving storage of the head pillow 12 and ankle pillow 22. At this time, the bed board 38 can also be used as a regular bed. Furthermore, the multifunctional bed frame provided in this embodiment utilizes a drive assembly to achieve synchronous adjustment of the headrest 11, ankle support 21, and bed board 38, making operation convenient. The first direction is... Figure 1 The ab direction in the middle.

[0043] The drive assembly includes a connecting cylinder and a transmission component. One end of the transmission component is slidably inserted into the connecting cylinder, forming a sealed accommodating cavity with the connecting cylinder. The accommodating cavity is sealed with incompressible transmission fluid. Specifically, such as... Figure 2As shown, the connecting cylinder includes a first cylinder 31, a second cylinder 32, and a third cylinder 33 that are vertically arranged and connected. The first cylinder 31, the second cylinder 32, and the third cylinder 33 all have openings on the side facing the bed board 38. The transmission components include a first transmission component 34, a second transmission component 35, and a third transmission component 36. One end of the first transmission component 34 is inserted into the opening of the first cylinder 31, and the other end is connected to the head support 11. One end of the second transmission component 35 is inserted into the opening of the second cylinder 32, and the other end is connected to the bottom of the bed board 38. One end of the third transmission component 36 is inserted into the opening of the third cylinder 33, and the other end is connected to the ankle support 21. When the bed board 38 moves downward, it drives the second transmission component 35 to move within the second cylinder 32, squeezing the transmission fluid downward. The fluid in the second cylinder 32, under pressure, flows into the first cylinder 31 and the third cylinder 33. The increased fluid in the first and third cylinders 31 and 33 then pushes the first and third transmission components 34 and 36 upward in the vertical direction, thus achieving synchronous squeezing by the first, second, and third transmission components 34, 35, and 36. In practice, the vertical movement distances of the first, third, and second transmission components 34, 36, and 35 may not be the same. The cross-sectional area of ​​the first, second, and third cylinders 31, 32, and 33 in the horizontal direction will affect the length of their vertical movement.

[0044] Optionally, the drive assembly further includes a drive member 37, and the second transmission member 35 includes a rotating part 351 and a transmission part 352. The first end of the rotating part 351 is rotatably connected to the bed plate 38, and the second end of the rotating part 351 is threadedly connected to the transmission part 352. The end of the transmission part 352 facing away from the rotating part 351 is slidably inserted through the opening of the second cylinder 32. The drive member 37 is used to drive the rotating part 351 to rotate. In a specific implementation, when the drive member 37 is activated, it will drive the rotating part 351 to rotate. Since the transmission part 352 is limited by the second cylinder 32, it can only slide along the axial direction of the second cylinder 32. The threaded connection between the rotating part 351 and the transmission part 352 will force the transmission part 352 to move along the axial direction of the rotating part 351. The axial direction of the second cylinder 32 and the axial direction of the rotating part 351 are both in the first direction. If the rotating part 351 rotates clockwise, the transmission part 352 moves towards the bed board 38 (i.e., moves upward), allowing more transmission fluid to flow into the second cylinder 32. At this time, the transmission fluid in the first cylinder 31 and the third cylinder 33 decreases, and the first transmission member 34 and the third transmission member 36, losing the support of the transmission fluid, will move downward. Conversely, if the rotating part 351 rotates counterclockwise, the transmission part 352 moves away from the bed board 38 (i.e., moves downward), forcing the transmission fluid in the second cylinder 32 to flow into the first cylinder 31 and the third cylinder 33. This causes the fluid levels in the first and third cylinders to rise, allowing the first transmission member 34 and the third transmission member 36 to move upward. The fluid levels in the first and third cylinders remain consistent, but the heights of the first transmission member 34 and the third transmission member 36 in the first direction can be adjusted as needed, allowing the headrest 12 and the ankle pillow 22 to have different heights in the first direction.

[0045] Optionally, the bed board 38 has a first through hole and a second through hole. The head assembly 1 moves through the first through hole, and the ankle assembly 2 moves through the second through hole. When the head assembly 1 moves upward, the headrest 12 can pass through the first through hole and be positioned above the bed board 38. When the ankle assembly 2 moves upward, the ankle pillow 22 can pass through the second through hole and be positioned above the bed board 38. In a specific implementation, the bed body 3 may also include a first movable plate and a second movable plate. The first movable plate can cover the first through hole when the headrest 12 is below the bed board 38, and the second movable plate can cover the second through hole when the ankle pillow 22 is below the bed board 38. The first and second movable plates can be used to cover the head assembly 1 and the ankle assembly 2 for easy storage, and can also form a complete plane with the bed board 38 to facilitate the use of the bed board 38 as a regular bed.

[0046] Furthermore, a first storage box 13 is provided at the first through hole. The first storage box 13 is located below the bed board 38 and can store the head assembly 1. Specifically, the top of the first storage box 13 has a first opening that communicates with the first through hole, and the bottom of the first storage box 13 has a first through hole. The head support 11 passes through the first through hole to extend out of the first storage box 13 and connect to the first transmission member 34 below the first storage box 13. When the first transmission member 34 moves upward, it can drive the headrest 12 to move through the first opening to the top of the bed board 38, and when the first transmission member 34 moves downward, it can drive the headrest 12 to move through the first opening and into the first storage box 13.

[0047] Similarly, a second storage box 23 is also provided at the second through hole. The second storage box 23 is located below the bed board 38 and can store the ankle component 2. Specifically, the top of the second storage box 23 has a second opening that communicates with the second through hole, and the bottom of the second storage box 23 has a second through hole. The ankle support 21 passes through the second through hole to extend out of the second storage box 23 and connect to the third transmission member 36 below the second storage box 23. When the third transmission member 36 moves upward, it can drive the ankle pillow 22 to move through the second opening to the top of the bed board 38, and when the third transmission member 36 moves downward, it can drive the ankle pillow 22 to move through the second opening and into the second storage box 23.

[0048] Optionally, the head support 11 includes a first support column 111 and a second support column 112. Both the first support column 111 and the second support column 112 are rotatably connected to the headrest 12. The end of the first support column 111 that is not connected to the headrest 12 is connected to the first transmission member 34, and the end of the second support column 112 that is not connected to the headrest 12 is connected to the first support column 111. The length of the second support column 112 along its own axial direction is adjustable. In specific implementation, the first support column 111 is set vertically, and the second support column 112 is set at an angle to the first support column 111. In the horizontal direction, the first support column 111 is connected to the side of the headrest 12 away from the ankle component 2, and the second support column 112 is connected to the side of the headrest 12 close to the ankle component 2. When the headrest 12 is in the initial position, the headrest 12 is parallel to the horizontal plane. When the length of the second support column 112 decreases, the second support column 112 will drive one side of the headrest 12 to rotate downward. The smaller the length of the second support column 112, the larger the angle between the headrest 12 and the horizontal plane. By adjusting the length of the second support column 112, the angle of the headrest 12 can be adjusted.

[0049] Optionally, the second support column 112 includes a sleeve and a connecting rod. The connecting rod is movably inserted into the sleeve. The end of the sleeve not connected to the connecting rod is rotatably connected to the first support column 111, and the end of the connecting rod not connected to the sleeve is rotatably connected to the headrest 12. The length of the second support column 112 can be adjusted by adjusting the length of the connecting rod inserted into the sleeve. The side wall of the sleeve is provided with multiple adjustment holes along its own axial direction. The outer wall of the connecting rod is provided with multiple elastic buckles, and a return groove is provided on the connecting rod corresponding to each elastic buckle. Pressing the elastic buckle will cause the elastic buckle to return into the return groove, which will push the connecting rod to move in the sleeve. When the elastic buckle is not pressed, it can be inserted into any of the adjustment holes, thereby realizing the adjustment of the length of the connecting rod inserted into the sleeve.

[0050] Optionally, the first transmission member 34 includes a first transmission rod portion 341 and a first transmission plate portion 342. One end of the first transmission rod portion 341 is inserted into the opening of the first cylinder 31, and the other end of the first transmission rod portion 341 is connected to the first support column 111 through the first transmission plate portion 342.

[0051] Optionally, the third transmission member 36 includes a third transmission rod portion 361 and a third transmission plate portion 362. One end of the third transmission rod portion 361 is inserted into the opening of the third cylinder 33, and the other end of the third transmission rod portion 361 is connected to the ankle bracket 21 through the third transmission plate portion 362.

[0052] Furthermore, the multifunctional bed frame also includes two clamping components 4, which are positioned opposite each other above the bed board 38 along a second direction. The two clamping components 4 are movable relative to the bed board 38 along the second direction. The clamping components 4 are used to abut against the patient's upper limbs. When both clamping components 4 are in contact with the patient's upper limbs, the patient can be easily secured to the bed board 38 for convenient treatment. The second direction is... Figure 4 In the direction cd, the second direction is perpendicular to the first direction.

[0053] Optionally, such as Figure 5 and Figure 6 As shown, the clamping assembly 4 includes a fixing member 41, a clamping bracket 42, and a clamping movable member 43. The fixing member 41 is disposed on the bed board 38. The clamping bracket 42 can move relative to the fixing member 41 in a second direction, and the clamping movable member 43 can move relative to the clamping bracket 42 in a second direction. The clamping movable member 43 is used to abut against the patient's upper limb. In specific implementation, not only can the clamping bracket 42 be adjusted to move relative to the fixing member 41, but the clamping movable member 43 can also be adjusted to move relative to the clamping bracket 42, thereby expanding the adjustment range of the clamping assembly 4.

[0054] In this embodiment, the fixing member 41 is a fixing box, which is disposed on the bed board 38. The fixing box has a cavity, and the side wall of the fixing box is provided with an internal threaded hole communicating with the cavity. The clamping bracket 42 includes a threaded post 421. One end of the threaded post 421 is located outside the cavity, and the other end passes through the internal threaded hole and abuts against the clamping moving member 43 located inside the cavity. Rotating the threaded post 421 can move the threaded post 421 relative to the internal threaded hole in a second direction. When the threaded post 421 moves toward the clamping moving member 43, it can push the clamping moving member 43 to move. Preferably, the clamping bracket 42 also includes a first knob, which is connected to the end of the threaded post 421 located outside the cavity, so as to facilitate the user to rotate the threaded post 421.

[0055] Optionally, the clamping moving member 43 includes a support plate 431, a rotating rod 432, a rack, and an arc-shaped member 434. The top wall of the fixed box is provided with a rotating hole communicating with the cavity. The rotating rod 432 passes through the rotating hole along a first direction and is rotatably connected to the fixed box. One end of the rotating rod 432 is located outside the cavity, and the other end of the rotating rod 432 passes through the rotating hole and is located inside the cavity. A gear is provided at the other end of the rotating rod 432. The rack is provided in the cavity and extends along a second direction. The gear meshes with the rack. The arc-shaped member 434 is provided at one end of the rack's extension direction. This end is the end where the two clamping moving members 43 approach each other. When the user rotates the rod 432, it drives the gear to rotate, thereby causing the rack to drive the arc-shaped member 434 to move in the second direction, so that the arc-shaped member 434 of one clamping moving member 43 can approach or move away from the arc-shaped member 434 of the other clamping moving member 43.

[0056] In specific implementation, such as Figure 7 As shown, the clamping moving part 43 also includes a limiting plate 433. Each clamping moving part 43 has two limiting plates 433, and each limiting plate 433 has a rack on its opposite side. Specifically, the clamping moving part 43 has a first rack 4331 and a second rack 4332. Both racks 4331 and 4332 are connected to the arc-shaped part 434. A first gear 4321 is provided at the end of the rotating rod 432 facing the first rack 4331, and the first rack 4331 meshes with the first gear 4321. The limiting plate 433 is located within the cavity of the fixed box, and its bottom abuts against the bottom of the cavity. The movement of the threaded post 421 can push the limiting plate 433 to move.

[0057] In specific implementation, such as Figure 7As shown, the support plate 431 also includes a connecting part 4311, which is located on the side of the support plate 431 near the rack. The support plate 431 also includes a second gear 4312, which meshes with the second rack 4332. The connecting part 4311 is provided with a mounting hole, and a rotating bearing is provided in the mounting hole. The second gear 4312 is rotatably connected to the side of the connecting part 4311 away from the rotating rod 432 through the rotating bearing. When the user rotates the rotating rod 432, the first gear 4321 meshes with the first rack 4331, thereby driving the first rack 4331 to move. The second rack 4332 and the arc-shaped part 434 move synchronously. The movement of the second rack 4332 will drive the second gear 4312 to rotate. The second gear 4312 rotates relative to the connecting part 4311, that is, the connecting part 4311 remains stationary. The user can rotate the threaded column 421 to move the support plate 431. When the support plate 431 moves to the side where the limiting plate 433 is away from the arc-shaped part 434, the support plate 431 can push the limiting plate 433 to move in the second direction. At this time, the first rack 4331 will drive the first gear 4321 to rotate, and the first gear 4321 will drive the rotating rod 432 to rotate. Since the moving direction and moving distance of the connecting part 4311 are relatively fixed with the moving direction and moving distance of the limiting plate 433, the second gear 4312, which is connected to the connecting part 4311 by the rotating bearing, only moves in the second direction under the drive of the connecting part 4311 and does not rotate itself. When the support plate 431 reaches the maximum moving distance, the rotating rod 432 is rotated, and the rotating rod 432 will drive the first gear 4321 to rotate. The first gear 4321 drives the first rack 4331 to move, further increasing the moving distance of the clamping moving part 43 in the second direction, thereby increasing the moving distance of the arc-shaped part 434. At this time, the movement of rack 4332 will drive gear 4312 to rotate, while the connecting part 4311 remains stationary under the action of the rotating bearing.
