Description

Technical Field

[0001] This invention relates to the field of orthopedic rehabilitation, specifically to a postoperative support system for fracture surgery. Background Technology

[0002] Pelvic fractures are a serious injury, and their treatment and rehabilitation are complex and lengthy. In the early stages of fracture healing, patients often require prolonged bed rest and face clinical needs such as regular turning to prevent pressure sores and promote blood circulation. However, due to the unique biomechanical characteristics of the pelvis and the poor stability of the fracture site, turning procedures must strictly adhere to specific medical requirements. The "axial turning" or "log rolling method" is commonly used, which involves keeping the head, neck, and trunk on the same axis during turning to minimize torsional or shear forces in the pelvic area and prevent secondary complications such as fracture displacement, internal fixation device failure, and neurovascular injury.

[0003] Currently, in clinical practice, this type of turning operation mainly relies on manual assistance from medical staff or nursing assistants. Although this method can ensure the standardization and safety of the operation to a certain extent, it still has significant limitations in actual implementation: on the one hand, hospital human resources are limited, and a nursing assistant often has to take care of multiple patients at the same time, making it difficult to respond to each patient's turning needs in a timely manner; on the other hand, although manual operation is trained, there are still individual differences, and stability and consistency cannot be fully guaranteed, especially under fatigue or emergency conditions, when operational errors are more likely to occur.

[0004] Therefore, there is a lack of a dedicated device in the existing technology that can safely, stably and efficiently assist patients with pelvic fractures in axial turning. There is a need for a structured, standardized turning assist device that can be used independently or semi-independently to reduce the burden on medical staff and improve the safety and comfort of patients during rehabilitation. Summary of the Invention

[0005] The present invention aims to provide a postoperative support system for fracture surgery, enabling patients to use turning aids independently or semi-independently.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a postoperative support system for fractures, comprising a control system and an execution system. The execution system includes a fixed support frame, a bed board, a sliding base, and a movable support frame. The bed board is supported on the fixed support frame and includes an outer frame. Two flip-up plates are provided inside the outer frame, and the two flip-up plates are respectively used to support the left and right halves of the patient's body. One end of each flip-up plate is rotatably connected to the outer frame, and the other end is detachably connected to the outer frame. The movable support frame is provided with a main drive component, which is detachably connected to the bed board and used to drive the bed board to rotate. The movable support frame is slidably mounted on the sliding base, and the two ends of the sliding base are located at the foot of the bed and the side of the bed, respectively. The control system includes a controller, a movement unit, and a position detection unit. The position detection unit detects whether the moving support frame is located at the foot or side of the bed. The movement unit drives the moving support frame to move. The controller includes rotation mode, movement mode, and flipping mode. When the patient is about to get out of bed, the position detection unit detects the position of the movable support frame. If the movable support frame is not detected to be on the side of the bed, the controller enters the movement mode and sends a signal to the movement unit. The movement unit drives the movable support frame to move along the sliding base to the side of the bed. Then, the controller enters the rotation mode and sends a signal to the main drive unit. The main drive unit connects to the side of the bed board and drives the bed board to rotate. When the patient is about to turn over, the position detection unit detects the position of the movable support frame. If the movable support frame is not detected at the foot of the bed, the controller enters the moving mode and sends a signal to the moving unit. The moving unit drives the movable support frame to move along the sliding base to the foot of the bed. Then, the controller enters the flipping mode and sends a signal to the main drive unit. The main drive unit connects to the foot of the bed board and drives one of the flipping plates to flip.

[0007] In this plan, the foot of the bed refers to the side where the patient's feet are when lying on the bed board. Similarly, the side where the head is is the head of the bed, and the sides of the bed are the two sides remaining besides the head and foot of the bed.

[0008] The beneficial effects of this plan are: 1. This solution improves upon existing hospital beds. Like existing bed boards, this solution's bed board also has a long side and a short side. It primarily targets patients with limited mobility after pelvic fracture surgery, reducing the range of pelvic movement when getting out of bed and decreasing the workload for medical staff or caregivers. The main principle is that by directly erecting the bed board, the patient can directly switch from a lying to a standing position. Only the bed sheet needs to be fixed to the bed board, and the top of the bedding can be hung on the bed board or the railings on both sides of the bed board. To facilitate patient movement after getting up, this solution does not include any obstructions at the foot of the bed.

[0009] 2. The rotating support frame serves as both a rotation center and a support, but its durability is insufficient. It is necessary to add a fixed support to bear the main weight of the patient when lying flat and to limit the movement. However, to facilitate rotation, no fixed connection is set between the bed board and the fixed support in this solution, but a detachable connection can be added as needed.

[0010] 3. Generally, when turning over, "axial turning" or "log rolling" is required, meaning that the entire spine and pelvis should move as a whole, like a log, avoiding any twisting, shearing, or separation of the pelvis. To achieve the above-mentioned axial turning effect while facilitating getting out of bed, this solution divides the bed board into an outer frame and two rotating panels inside the outer frame: the outer frame is mainly responsible for the long-side rotation function to assist getting out of bed; the rotating panels are mainly responsible for the short-side turning function, pushing the patient's body on one side upwards through rotation, thereby assisting turning over. Patients can use this turning assistance device independently or semi-independently with assistance, which can reduce the burden on medical staff and improve the safety and comfort of patients during rehabilitation.

[0011] The above two functions are achieved by the controller switching between three modes, and the output signal of the position detection unit determines whether to enter the movement mode. After confirming that the moving support frame has reached the corresponding position, the main drive component and the outer frame are connected, thereby driving the outer frame to rotate. In this solution, the same drive component is used to achieve the above two functions, and the rotation is achieved through the main drive component. This reduces the space occupied by the structure, does not hinder the patient from walking after getting up, simplifies the structure, and saves production and maintenance costs.

[0012] Furthermore, in the flipping mode, the mobile support frame moves to the foot of the bed and aligns with one of the flipping plates, which is on the fixed side and rotatably connected to the outer frame. The other flipping plate is on the flipping side and fixedly connected to the outer frame. The main drive unit is connected to the corresponding position of the outer frame, and the main drive unit drives the outer frame and the flipping plate on the flipping side to rotate together, thereby assisting the patient to turn over.

[0013] If the main drive unit is directly connected to the flipping plate on the flipping side, the flipping plate will inevitably rotate around the output shaft of the main drive unit. However, the patient's body can only rotate around a support point, which is a point on the fixed-side flipping plate. The misalignment of the body's and the flipping plate's rotation centers means the flipping plate cannot always remain against the patient's back, causing the speed and angle at which the flipping plate pushes the patient to constantly change, thus increasing the risk of injury to the affected area. Therefore, this design sets the rotation center of the flipping plate on the fixed side, making the rotation center of the flipping plate as consistent as possible with the body's rotation center. However, this also prevents the main drive unit from directly connecting to the flipping plate on the flipping side. Therefore, in this design, an outer frame is added, and the main drive unit connects to the outer frame, thereby causing the flipping plate on the flipping side to flip, thus aligning the rotation center of the flipping plate with the body's rotation center and reducing the risk of injury to the affected area.

[0014] Furthermore, the fixed support frame is equipped with several fixed cylinders, the output shafts of which are inserted to fix the corresponding side of the flip plate. With this configuration, when assisting the patient to turn over, the output shafts of the fixed cylinders are inserted and fixed to the corresponding side of the flip plate, so that the flip plate can support the patient's body.

[0015] Furthermore, the bed board is divided into an upper projection area and a lower projection area according to the planar projection. The upper projection area is used to support the patient's upper body and is supported on a fixed frame. The lower projection area is used to support the patient's lower body. In rotation mode, the movable support frame moves to the side of the lower projection area of ​​the bed board, the output shaft of the main drive unit is connected to the lower projection area, and the output shaft of the main drive unit is parallel to the short side of the bed board. The main drive unit rotates the bed board in the forward direction, causing the upper projection area to rise so that the patient can lean against the bed board while standing. The main drive unit drives the bed board to rotate in the opposite direction, returning the bed board to its initial state.

[0016] With this setup, since the bed board is usually 400mm-600mm off the ground, the rotation center is set as close to the foot of the bed as possible to prevent the bed board from colliding with the ground after rotation, ensuring that there is a gap between the bed board and the ground after rotation.

[0017] Furthermore, an auxiliary drive is provided on the side of the bed board away from the main drive. The output shaft of the auxiliary drive is parallel to that of the main drive in rotation mode, and an auxiliary gear is connected to the output shaft of the auxiliary drive. An arc-shaped rack is provided on the fixed support frame. The center of the arc-shaped rack is collinear with the output shaft of the main drive, and the arc-shaped rack meshes with the auxiliary gear.

[0018] With this setup, the main drive unit would require a large power and a larger motor to rotate the patient and the bed. Therefore, this solution adds an auxiliary drive unit at the head of the bed, which rotates the head of the bed through the cooperation of an auxiliary gear and an arc rack; while the main drive unit mainly rotates the foot of the bed, reducing costs and saving space.

[0019] Furthermore, the inner side of the outer frame near the headboard is provided with a pivot, and the upper surface of the flip-up plate near the headboard is provided with a rotating part. The pivot is inserted into the rotating part and rotates in connection with the rotating part.

[0020] Furthermore, a sleeve is provided on the upper surface of the flip plate near the foot of the bed, and a threaded rod is connected to the inner thread of the sleeve. The inner side of the threaded rod is hollow and has internal teeth. The outer frame side of the lower projection area is provided with two horizontal through first connecting holes; each first connecting hole includes a first rotating section, a first moving section and a first meshing section from the outside to the inside. The cross section of the first moving section covers the first rotating section, and the first meshing section is provided with internal teeth. The inner diameter of the first rotating section is smaller than the outer diameter of the first meshing section. The outer frame of the lower projection area has two horizontally penetrating second connecting holes on the tail side. Each second connecting hole includes a second meshing section, a second moving section, and a threaded section from the outside to the inside. The threaded section is used to connect with the end of the threaded rod. The second meshing section has internal teeth. The inner cross section of the threaded rod is the same as the cross section of the second meshing section. The cross section of the second moving section covers the cross section of the second meshing section. Each flip plate is equipped with one first connection hole and one second connection hole; An arc-shaped moving channel connects the first moving segment and the second moving segment. The bottom of the moving channel, the first moving segment, and the second moving segment are all provided with internal teeth. The three internal teeth are continuously arranged to form a bottom internal tooth with an arc-shaped tooth profile. The movable support frame is equipped with a movable cylinder. The output shaft of the movable cylinder is connected to the main drive component. The output shaft of the movable cylinder and the output shaft of the main drive component are coaxial. The output shaft of the main drive component includes a third rotating section. The end of the third rotating section is provided with a third meshing section. The third meshing section is provided with external teeth in the circumferential direction. In the rotation mode, the output shaft of the fixed cylinder and the tilting plate are separated. The output shaft of the main drive component is in the first connecting hole: the third meshing section meshes with the first meshing section, the third rotating section is rotatably connected with the first rotating section, and the threaded rod of the tilting plate is threadedly connected to the threaded section of the corresponding second connecting hole. In the moving mode, the output shaft of the fixed cylinder on the fixed side is inserted into the corresponding flip plate, and the output shaft of the main drive component on the fixed side moves from the first connecting hole to the second connecting hole. The moving cylinder drives the third meshing section to retract into the first moving section, the third meshing section meshes with the bottom internal teeth, and the main drive component drives the third meshing section to rotate. The third meshing section passes through the first moving section, the moving channel and the second moving section in sequence. When the patient is about to get out of bed, if the mobile support frame is not detected to be located on the side of the bed, the controller enters the mobile mode and sends a signal to the main drive unit, causing the output shaft of the main drive unit to rotate in the positive direction. When the patient is about to turn over, if the mobile support frame is not detected at the foot of the bed, the controller enters the mobile mode and sends a signal to the main drive unit, causing the output shaft of the main drive unit to rotate in the opposite direction. In the flip mode, the output shaft of the main drive unit on the fixed side is inserted into the threaded rod, the third engagement section engages with the inner side of the threaded rod, the main drive unit drives the threaded rod to rotate, the threaded rod and the corresponding threaded section of the second connecting hole separate, the moving cylinder drives the third engagement section to retract to engage with the second engagement section, and the third engagement section drives the outer frame and the flip plate on the flip side to rotate.

[0021] Furthermore, it also includes a sliding base with a sliding groove, which is set according to the movement trajectory of the mobile support frame in the movement mode; the bottom of the mobile support frame is provided with a slider, which is slidably set in the sliding groove, and the mobile support frame is supported on the sliding base.

[0022] With this configuration, the main drive output shaft can be extended or retracted by a movable cylinder, thereby switching the engagement position; the movable cylinder drives the threaded rod to rotate, thereby switching the flip plate and the outer frame between fixed connection and rotational connection; the main drive drives the third engagement section to rotate, and the third engagement section engages with the bottom internal teeth, thereby driving the movable support frame to move along the moving channel together, that is, the moving channel plays a guiding role here.

[0023] The sides of the outer frame refer to the two sides of the outer frame excluding the headboard and footboard.

[0024] Furthermore, the position detection unit includes a first signal transmitter and two first signal receivers. The first signal transmitter is embedded in the lower surface of the slider, and the two first signal receivers are respectively embedded in both ends of the slide groove. The two first signal receivers correspond to the tail and side positions of the movable support frame, respectively. The first signal transmitter sends a signal downward. If the first signal receiver at the corresponding position receives the signal, the controller can identify whether the movable support frame is in the corresponding position.

[0025] Furthermore, it also includes an angle detection unit, which includes a second signal transmitter and two second signal receivers. The second signal transmitter is embedded in the movable support frame near the outer frame, and the two second signal receivers are embedded in the foot and side positions of the outer frame, respectively. The two second signal receivers correspond to the foot and side positions of the movable support frame, respectively. The second signal transmitter sends a signal to the outer frame. When the second signal receivers align with the second signal transmitter and receive the signal, it indicates that the outer frame has rotated to the design angle, thereby causing the controller to control the main drive unit to stop running. The maximum design angle is 90° in both rotation and flip modes.

[0026] With this setting, the bed board will stop rotating when it reaches the designed angle, avoiding excessive rotation that could cause the patient to lose balance (in rotation mode) or be squeezed (in flipping mode). Attached Figure Description

The execution system includes a fixed support frame 1, a bed board 2, a sliding base 3, and two movable support frames 4. This embodiment only shows the main structure; the reinforcing support structure is set according to the actual situation. In this embodiment, the central axis 52 of the bed board refers to the central axis parallel to the length direction of the bed board 2. All central axes mentioned in this embodiment are parallel to the central axis 52 of the bed board.

[0030] like Figure 9As shown, the fixed bracket includes a supporting beam 11 and two supporting legs. The two supporting legs are bolted to the left and right ends of the supporting beam 11, respectively. The cross-sectional shapes of the supporting beam 11 and the right supporting leg are as follows: Figure 3 The pentagons and trapezoids shown have the following cross-sectional shapes for the left supporting leg: Figure 3 and Figure 5 As shown, the side of the support beam 11 is inclined, and two fixed cylinders 14 are embedded in the support beam 11.

[0032] The bed board 2 is divided into an upper projection area and a lower projection area according to the planar projection. The supporting beam 11 is used to support the upper projection area of ​​the bed board 2. Figure 9 (Left side of the bed), the bed board 2 is used for the patient to lie flat on it, and the right edge of the support beam 11 extends from the lower projection area of ​​the bed board 2.

The lower surface shape of the flip-up plates 22 matches the shape of the supporting beam 11. The two flip-up plates 22 are used to support the left and right halves of the patient's body, respectively. One end of each flip-up plate 22 is rotatably connected to the outer frame 21, and the other end is detachably connected to the outer frame 21, thereby allowing the flip-up plates 22 and the outer frame 21 to switch between a fixed connection and a rotatable connection. Figure 7 , Figure 8 As shown, the inner side of the outer frame 21 near the headboard has two integrally formed rotating shafts 26, which correspond to two flip plates 22 respectively. The upper surface of the flip plate 22 near the headboard (left side) has an integrally formed rectangular rotating part 27. The rotating shaft 26 is inserted into the rotating part 27 and rotatably connected to the rotating part 27. The upper surface of the flip plate 22 near the footboard (right side) has an integrally formed sleeve 28. The outer side of the sleeve 28 is rectangular and the inner side is circular. The sleeve 28 is internally threaded with a threaded rod 29. The inner side of the threaded rod 29 is hollow and has internal teeth. The threaded rod 29 and the corresponding rotating shaft 26 are coaxial and are the rotation center axis 51 of the flip plate 22.

[0033] like Figure 2 , Figure 7 As shown, an auxiliary slot 23 is provided at the upper and lower corners on the left side of the outer frame 21. An auxiliary motor 24 is bolted to each of the auxiliary slots 23. The auxiliary motor 24 is the auxiliary drive mentioned above.

[0034] like Figure 3 , Figure 4 As shown, the outer frame 21 has horizontally penetrating first connecting holes on both sides (except for the sides near the head and foot of the bed). The first connecting holes are located within the lower projection area. The first connecting holes include a first rotating section L1, a first moving section L2, and a first meshing section L3 from the outside to the inside. The cross section of the first moving section L2 covers the first rotating section L1. The first meshing section L3 is provided with internal teeth. The inner diameter of the first rotating section L1 is smaller than the outer diameter of the first meshing section L3. The outer frame 21 of the lower projection area has two horizontally penetrating second connecting holes on the tail side. Each second connecting hole includes a second meshing section L1', a second moving section L2', and a threaded section L3' from the outside to the inside. The threaded section L3' is used to connect with the end of the threaded rod 29. The second meshing section L1' has internal teeth. The inner cross section of the threaded rod 29 is the same as the cross section of the second meshing section L1'. The cross section of the second moving section L2' covers the cross section of the second meshing section L1'. A flip plate 22 is provided with a first connection hole and a second connection hole; An arc-shaped moving channel connects the first moving segment L2 and the second moving segment L2'. The bottom of the moving channel, the first moving segment L2, and the second moving segment L2' are all provided with internal teeth. The three internal teeth are continuously arranged to form a bottom internal tooth with an arc-shaped tooth profile. like Figure 9 , Figure 10 As shown, the sliding base 3 is mounted on the ground to the right of the fixed bracket, as... Figure 2 , Figure 7 As shown, the sliding base 3 is elongated, with its two ends located on the upper and lower sides of the right side of the bed board 2, respectively. A first rectangular base 32 is integrally formed at each end of the curved base. A second rectangular base 33 is integrally formed in the middle of the curved base, located at the right end of the bed board 2. A sliding groove is formed on the upper surface of the curved base, comprising two symmetrical curved grooves 31 about the central axis 52 of the bed board. A portion of the moving channel is parallel and equidistant from the curved grooves 31. One end of each curved groove 31 is located on the first rectangular base 32, and the other ends of the two curved grooves 31 intersect on the second rectangular base 33. The portion of the curved base between the first rectangular base 32 and the second rectangular base 33 is curved. Figure 9 As shown, the right edge of the bed board 2 and the arc-shaped base are shaped and equidistant.

[0035] Two movable support frames 4 are slidably mounted on two arc-shaped grooves 31 respectively. The movable support frame 4 is rectangular, and a slider that matches the shape of the arc-shaped groove 31 is integrally formed on the lower surface of the movable support frame 4. In this embodiment, the slider is an arc-shaped protrusion, and the arc-shaped protrusion is slidably mounted in the arc-shaped groove 31. The movable support frame 4 has a drive cavity inside, such as Figure 11As shown, a movable cylinder 41 is bolted into the drive cavity. A connector 43 is bolted to the right end of the output shaft of the movable cylinder 41. A main drive component 42 is bolted to the left side of the connector 43. The main drive component 42 is a servo motor. The output shaft of the main drive component 42 and the output shaft of the auxiliary motor 24 are parallel in direction. The center of the arc-shaped rack 13 is collinear with the output shaft of the main drive component 42. The output shaft of the main drive component 42 includes a third rotating section L4. A third meshing section L5 is provided at the left end of the third rotating section L4. The third meshing section L5 has external teeth in the circumference, that is, the third meshing section L5 is gear-shaped.

[0036] The control system includes a controller, a movement unit, and a position detection unit. The controller is bolted to any position on the fixed support frame 1. In this embodiment, the controller is bolted to the lower surface of the support beam 11. The position detection unit is used to detect whether the movable support frame 4 is located at the foot or side of the bed. The movement unit is used to drive the movable support frame 4 to move. The controller includes a rotation mode, a movement mode, and a flipping mode. The rotation mode is used to assist getting in and out of bed, the flipping mode is used to assist turning over, and the movement mode is used to switch between the rotation mode and the flipping mode.

[0037] The position detection unit includes a first signal transmitter and two first signal receivers 61. The first signal transmitter is embedded in the lower surface of the slider (not shown in the attached figure), as... Figure 2 , Figure 7 As shown, two first signal receivers 61 are respectively embedded at both ends of the slide groove. The two first signal receivers 61 correspond to the foot and side positions of the movable support frame 4, respectively. The first signal transmitter sends a signal downward. If the first signal receiver 61 at the corresponding position receives the signal, the controller can identify whether the movable support frame 4 is in the corresponding position.

[0038] In this embodiment, the rotation axis 51 on the corresponding side is defined as the x-axis, and the center of the arc-shaped groove 31 is defined as the origin o. Then, as follows... Figure 2 As shown, the foot of the bed is located on the x-axis with coordinates a(x0, 0), and 50cm ≥ x0 ≥ 30cm; the side of the bed is located on the y-axis with coordinates b(0, y0), and 50cm ≥ y0 ≥ 30cm. It also includes an angle detection unit, such as Figure 9 , Figure 10 , Figure 12 , Figure 13As shown, the angle detection unit includes a second signal transmitter 62 and two second signal receivers 63 (all shown as squares in the figure, not representing the actual shape; the actual shape can be circular, strip-shaped, or square). The second signal transmitter 62 is embedded in the movable support frame 4 near the outer frame. The two second signal receivers 63 are embedded in the foot and side positions of the outer frame 21, respectively. The two second signal receivers 63 correspond to the foot and side positions of the movable support frame 4, respectively. The second signal transmitter 62 emits an infrared signal toward the outer frame 21. When the second signal receivers 63 align with the second signal transmitter 62 and receive the infrared signal, it indicates that the outer frame 21 has rotated to the designed angle, thereby causing the controller to control the main drive unit 42 to stop running. In this embodiment, the receiver refers to the infrared receiver and the transmitter refers to the infrared transmitter.

[0039] The maximum design angle is 90° in both rotation and flip modes. In this embodiment, the design angle is 60°. The controller connection is as follows: Figure 1 As shown, the controller is electrically connected to the first signal transmitter 62, the second signal transmitter 62, the first signal receiver 61, the second signal receiver 63, the main drive unit 42, the auxiliary motor 24, the moving cylinder 41, and the fixed cylinder 14, respectively.

[0040] The method of using a post-fracture support system is as follows: 1. When the patient is about to get out of bed, the position detection unit detects the position of the movable support frame 4. If the first signal receiver 61 located on the side of the bed sends a signal to the controller, it indicates that the movable support frame 4 is located on the side of the bed, and the controller enters the rotation mode. In rotation mode, the initial state is as follows Figure 7 , Figure 9 As shown, the upper part of the bed board 2 is supported on the fixed support frame 1 so that the patient can lie flat on the bed board 2 and the bed sheet is covered on the bed board 2; the movable support frame 4 is supported on the first rectangular base 32; the output shaft of the fixed cylinder 14 is separated from the flip plate 22, and the output shaft of the main drive component 42 is in the first connecting hole: the third meshing section L5 meshes with the first meshing section L3, the third rotating section L4 is rotatably connected to the first rotating section L1, and the threaded rod 29 of the flip plate 22 is threadedly connected to the threaded section L3' of the corresponding second connecting hole; When getting out of bed, hang the bedding on the left side in a fixed position. The fixed position can be set according to the situation, such as a railing on the side of the bed board 2, or a hook on the left end of the bed board 2. Prepare slippers in advance on the second rectangular base 33. The output shaft of the main drive unit 42 is in the first connecting hole: the third meshing section L5 and the first meshing section L3 are meshed, and the third rotating section L4 and the first rotating section L1 are rotatably connected. The controller sends a start signal to the main drive unit 42, and the main drive unit 42 drives the outer frame 21 of the bed board 2 to rotate in the forward direction, so that the upper part of the bed board 2 rises and the bed board 2 begins to tilt.

The controller controls the main drive unit 42 to drive the third meshing section L5 to rotate in the opposite direction (when the moving support frame 4 moves to the side of the bed, the output shaft of the main drive unit 42 rotates in the opposite direction, and vice versa). The third meshing section L5 passes through the first moving section L2, the moving channel and the second moving section L2' in sequence. During this process, the main drive unit 42 drives the moving support frame 4 to slide on the sliding base 3, from the first rectangular base 32 to the second rectangular base 33. When the first signal receiver 61 on the side of the bed sends a signal to the controller, the controller controls the main drive unit 42 to stop running. When the patient is ready to turn over (step four), the above steps are performed in reverse.

[0042] 3. When the patient prepares to turn over, the position detection unit detects the position of the movable support frame 4.

[0043] When the patient wants to turn over, the main drive 42 drives the flipping plate 22 on the flipping side to rotate, thereby pushing the patient's body to turn over as a whole.

[0044] 4. When the patient is about to turn over, the position detection unit detects the position of the moving support frame 4. If the second signal receiver 63 located on the side of the bed does not send a signal to the controller, the controller will first enter the moving mode before entering the rotation mode and reverse step 2.

[0045] In this embodiment, when the patient turns over, the movable support frame 4 is located at the foot of the bed, but when the patient gets out of bed, the movable support frame 4 needs to return to the side of the bed, otherwise it will block the patient from getting out of bed.
