Description

Technical Field

[0001] The present invention relates to the technical field of ward nursing equipment, and in particular to a bed-moving device. Background Art

[0002] People who are bedridden for a long time (such as those recovering from surgery, the elderly or those with mobility difficulties) have difficulty getting out of bed on their own due to muscle atrophy, osteoporosis and other problems. Traditional manual carrying and side-rolling methods can easily cause secondary injuries and place a heavy burden on caregivers.

[0003] While current nursing beds that combine a wheelchair and a bed have somewhat solved the problem of transferring bedridden patients, their transmission mechanisms often suffer from instability and cumbersome operation, leading to stalling or misalignment during position changes, increasing the risk of falls. Furthermore, while some nursing beds with rotating structures allow for smooth exits and exits, their mechanical design is complex and relies on a multi-stage transmission system. This not only increases manufacturing costs and makes maintenance difficult, but also occupies a large space, making them difficult to adapt to the actual scenarios of ordinary homes or medical institutions. Summary of the Invention

[0004] The main purpose of the present invention is to provide a device for getting out of bed and shifting, aiming to solve the problems of insufficient stability, cumbersome operation, risk of falling, complex mechanics and large space occupied in the existing technology.

[0005] To achieve the above-mentioned object, the present invention provides a device for moving out of bed, comprising: The body support board is composed of multiple boards that are hingedly connected in sequence. It is used to support the body of the bedridden person and can move back and forth between the foot of the bed and the head of the bed; The track includes a translation section and a vertical translation section, and is used for slidingly mounting a body support plate. The body support plate can slide from the translation section to the vertical translation section to allow the bedridden person's lower legs to droop and bend or move out of the bed surface. The power system is used to drive the body support plate to move back and forth on the track.

[0006] Furthermore, there are two rails which are respectively arranged on both sides of the bed body, and the body support plate is slidably installed between the two rails.

[0007] Furthermore, the track is a groove-type track, and rollers for rolling with the corresponding track are respectively provided on both sides of each plate body of the body support plate.

[0008] Furthermore, the power system is connected between the bed and the body support plate.

[0009] Furthermore, there is a smooth transition between the translation section and the vertical translation section.

[0010] Furthermore, the track also includes a stock segment, and there is a smooth transition between the stock segment and the vertical movement segment, and the stock segment, the translation segment, and the vertical movement segment form a U-shape.

[0011] Furthermore, the first plate of the torso support plate serves as a buttocks support plate for supporting the buttocks of the bedridden person, and the remaining plates of the torso support plate serve as leg support plates for supporting the legs of the bedridden person.

[0012] Furthermore, the size of the hip support plate is larger than that of the leg support plate.

[0013] Furthermore, adjacent plates of the body support plate are hingedly connected via hinges.

[0014] Furthermore, the device also includes a back-lifting mechanism for lifting the upper body of the bedridden person.

[0015] The beneficial effects of the present invention are embodied in: The present invention innovatively adopts a design that combines rail-type transmission with plate-type support, integrating the load-bearing advantages of plate-type transportation with the guiding advantages of rail-type transportation. The body support plate is designed to be composed of multiple plates that are hinged and connected in sequence to form a multi-segment foldable bed plate chain. This flexible chain plate structure can form a continuous load-bearing surface that perfectly fits the curve of the human body, inheriting the characteristics of high load-bearing capacity and segmented adaptability of the plate conveyor. In conjunction with the horizontal and vertical sections of the track, body position changes can be achieved. The bed-moving device of the present invention is simple to operate, and the position of the bedridden person changes little, making it very suitable for bedridden people. At the same time, it can achieve a smooth and accurate shift of the bedridden person from the bed surface to the end of the bed, solving the existing problems of insufficient stability, cumbersome operation, risk of bedridden people falling, and complex mechanical design.

DETAILED DESCRIPTION

[0018] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0019] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0020] In order to simplify the explanation, the following example is based on a typical scenario of bedridden people getting out of bed and moving. Figures 1 to 3 .

[0021] The device for getting out of bed and shifting according to the present invention comprises: The body support plate 10 is composed of a plurality of plates that are hingedly connected in sequence, and is used to support the body of the bedridden person and can move back and forth between the foot of the bed and the head of the bed; The track 20 includes a translation section 201 and a vertical translation section 202, and is used for slidingly mounting the body support plate 10. The body support plate 10 can slide from the translation section 201 to the vertical translation section 202 to allow the bedridden person's lower legs to droop and bend or move out of the bed surface. The power system 30 is used to drive the body support plate 10 to move back and forth on the track 20 .

[0022] The present invention is a device for moving the bed out of bed, which is simple to operate and minimizes changes in the patient's body position. It is very suitable for bedridden patients and can achieve smooth and precise movement of the bedridden patient from the bed surface to the foot of the bed, solving the problems of existing devices such as insufficient stability, cumbersome operation, risk of falling, and complex mechanical design. The process includes three stages: a startup stage, in which the bedridden's body lies flat on the body support plate, and the power system applies an initial thrust to overcome the friction between the body support plate and the track. A translation stage, in which the bedridden's body remains flat on the body support plate, and the power system drives the body support plate to gradually slide toward the foot of the bed along the translation section of the track. A flip stage, in which the tail end of the leg support plate enters the vertical section of the track, and the bedridden's lower leg gradually becomes suspended in the air without the support of the body support plate until the knee is naturally bent, smoothly completing the leg bending of the bedridden patient and achieving non-interventional adaptive flipping. At this point, the bedridden's upper body can be lifted to a sitting position. Of course, the bedridden can also be asked to sit up first, and then move to the foot of the bed using the device of the present invention to complete the process of getting out of bed. Through the innovative design of combining rail-type transmission and plate-type support, the load-bearing advantages of plate-type transportation and the guiding advantages of rail-type transportation are integrated, and the body support plate is designed to be composed of multiple plates hingedly connected in sequence to form a multi-segment foldable bed plate chain. This flexible chain plate structure can form a continuous load-bearing surface that perfectly fits the curve of the human body. It inherits the characteristics of high load-bearing capacity (evenly distributing the weight of the bedridden person) and segmented adaptability (each plate can independently adjust the angle) of the plate conveyor. In conjunction with the horizontal and vertical movement sections of the track, body position changes can be achieved.

[0023] The in-bed shifting device of the present invention is integrated into the tail end of the nursing bed, so that the bedridden person can complete the movement of getting out of bed at a natural and comfortable height, ensuring the safety and humanization of the shifting process; its structural design is compact and reasonable, only requires a single power system to drive, and the transmission mechanism is simple and reliable; at the same time, the design has good scalability and can be used in conjunction with the back-lifting mechanism, so that the bedridden person can maintain the optimal body position during the shifting process.

[0024] In addition, the bed-moving device of the present invention can also be expanded to the field of rehabilitation training. For example, by adding sensors to the support plate, the weight distribution and movement trajectory of the bedridden person can be monitored in real time, providing data support for rehabilitation evaluation, which is especially beneficial for the progressive rehabilitation training of long-term bedridden people, improving their independent mobility ability and quality of life.

[0025] In one embodiment, the power system 30 is connected between the bed frame 50 and the torso support board 10. Two rails 20 are provided, one on each side of the bed frame 50, and the torso support board 10 is slidably mounted between the two rails 20. This design is simple and easy to manufacture. Of course, the structure can be mounted on a separate bracket rather than the bed frame, and the bracket can be placed on the bed frame during use.

[0026] In one embodiment, the power system 30 is hingedly connected to the bed frame 50 and the body support plate 10 to avoid motion interference.

[0027] In one embodiment, the track 20 is a grooved track, and rollers 104 are provided on both sides of each plate of the body support plate 10 for rolling engagement with the corresponding track 20. This design reduces friction during rolling engagement, ensuring smooth rolling of the rollers within the track, facilitating smoother sliding of the body support plate, while also providing necessary guiding stability to prevent offset or jamming during operation. This engagement makes the entire shifting process smoother and quieter, significantly reducing the vibration and noise caused by traditional sliding friction. In a specific implementation, the cross-section of the track's groove can be designed to be U-shaped to facilitate installation of the rollers within the track's groove. The track's groove provides dual upper and lower rolling surfaces, which constrain the rollers and achieve high-precision path control, retaining the advantages of smooth track transport (no elastic sliding) and scalability (flexible track length adjustment). The rollers automatically switch rolling surfaces at track bends, with the upper rolling surface providing horizontal support and the lower rolling surface providing flipping guidance.

[0028] In one embodiment, a smooth transition is provided between the translational section 201 and the vertical translation section 202. Specifically, the smooth transition portion (i.e., the turning point) between the translational section and the vertical translation section is designed to be arc-shaped. This design allows for a smoother sliding transition and not only completes conventional linear movement but also achieves ergonomic posture adjustment, helping bedridden patients get out of bed safely while also preventing secondary injuries to patients with osteoporosis during the movement process.

[0029] In one embodiment, the track 20 further includes a stock section 203, and there is a smooth transition between the stock section 203 and the vertical movement section 202. The stock section 203, the translation section 201, and the vertical movement section 202 form a U-shape. The height of the bed limits the length of the vertical movement section of the track. The design of the stock section in the track allows longer body support plates to slide through the vertical movement section and into the stock section, thereby accommodating bedridden people of different body shapes. During installation, the rollers on the body support plate can be installed from the tail of the stock section of the track. After the body support plate and the power system are installed, it is ensured that the rollers will not slide out of the track when the bedridden person completes the action of getting out of bed. In a specific implementation, the smooth transition portion (i.e., the turning point) between the vertical movement section and the stock section is also designed to be arc-shaped to facilitate the passage of the leg support plate.

[0030] In one embodiment, multiple panels are arranged sequentially along the extension direction of the track 20 and hingedly connected to each other. The first panel of the torso support panel 10 serves as the hip support panel 101, which supports the bedridden user's hips. The remaining panels of the torso support panel 10 serve as the leg support panels 102, which support the bedridden user's legs. This design allows the hip support panel to slide only within the track's translational section without turning, while the leg support panel must navigate the track's turns. Furthermore, the two panels support different locations and weights, making this differentiated design more rational and facilitating differentiated design. In practice, the number of leg support panels 102 is preferably no less than two.

[0031] In one embodiment, the hip support plate 101 is larger than the leg support plate 102. The leg support plate's smaller size (primarily its width along the longitudinal direction of the bed) makes it easier to navigate around track bends, while the hip support plate does not need to enter the vertical section of the track or navigate around track bends. Its larger size provides better support for the hips and waist.

[0032] The hinged structure between the leg supports 102 allows for angular adjustment based on the curvature of the track, enabling smooth repositioning of the patient's lower limbs. The hinge points of the hinged structure are carefully positioned to ensure that when the leg supports are rotated, the patient's knee joints remain in a naturally ergonomically bent position, avoiding excessive flexion that stresses the joints and insufficient extension that compromises mobility.

[0033] In one embodiment, the adjacent plates of the torso support plate 10 are hingedly connected via hinges 103. The hinge points are linked to the curvature of the track, allowing the leg support plate's tilt angle to automatically match the track, providing both the surface support function of a plate-type mechanism and the linear guidance function of a track mechanism. In addition to hinges, bearing connections can also be used. Bearing connections are suitable for scenarios requiring high load-bearing capacity. The articulation method can be selected based on different needs, but the leg support plate must ensure smooth turning at the track bend to achieve smooth bending of the bedridden patient's lower limbs.

[0034] The bed-moving device of the present invention mainly realizes the following two movement modes: During horizontal translation movement, the power system 30 is activated to allow the bedridden person to move smoothly from a lying position on the bed surface toward the end of the bed. At this time, the hip support plate 101 and the leg support plate 102 slide linearly along the translation section 201 of the track 20, ensuring that the bedridden person's body remains stable and avoiding secondary injuries caused by sudden acceleration or deceleration.

[0035] Adaptive flipping movement, the leg support plate 102 is designed with multiple blocks, and each block is hingedly connected. When the bedridden person's lower limbs need to adjust their posture to adapt to getting out of bed, the leg support plate 102 naturally flips at the circular arc turning point of the track 20 and naturally adjusts its angle during the shifting process, so that the knee joint and ankle joint are at an ergonomic bending angle, avoiding unnecessary pressure on the bedridden person's lower limbs and bone or muscle damage caused by forced twisting.

[0036] The combination of these exercise patterns can be flexibly adjusted to suit the physical conditions (such as degree of osteoporosis, joint mobility) and care needs (such as progressive rehabilitation training or rapid transfer) of different bedridden people.

[0037] The bed shifting device of the present invention includes three main movement directions: The first direction (the longitudinal direction of the bed, i.e., the head-to-tail direction), the second direction (the vertical direction of the bed), and the third direction (the transverse direction of the bed, i.e., the left-right direction). The power system 30 is arranged along the first direction to drive the hip support plate 101 for longitudinal displacement; the track 20 provides support and guidance in the second direction to ensure stability during the displacement process; and the rollers 104 are symmetrically arranged in the third direction to ensure the balance of the mechanism operation. The linear movement in the first direction corresponds to the longitudinal displacement of the bedridden body; the track support in the second direction provides a stable constraint in the vertical direction; and the symmetrical pulley arrangement in the third direction ensures lateral balance. The out-of-bed displacement device of the present invention can achieve multi-dimensional adjustment of the bedridden body position through the coordinated cooperation of these three directions: the translational movement along the first direction allows the bedridden to move from the bed surface to the end of the bed; the height adjustment in the second direction can adapt to different bed surface height requirements; and the symmetrical support design in the third direction ensures that the displacement process does not tilt laterally. This multi-directional coordinated control makes the displacement process smoother and more natural, and can adapt to the special needs of bedridden people of different body shapes.

[0038] In one embodiment, the back-lifting mechanism 40 is further included for lifting the upper body of the bedridden person. The back-lifting mechanism can adopt existing technology, such as the adjustable virtual center rotation device disclosed in application number CN202510256797.X.

[0039] With this design, the bed-getting-out shifting device can be combined with the back-lifting mechanism for movement. The back-lifting board slowly tilts and lifts the upper body of the bedridden person, and the hip and waist support board and the leg support board move horizontally toward the end of the bed to bend the legs of the bedridden person, thereby achieving the bed-getting-out action. According to the characteristics of the user, the most comfortable body position can be maintained during the shifting process, thereby smoothly achieving the bedridden person's bed-getting-out action.

[0040] In one embodiment, the power system 30 may be an electric push rod, a ball screw or a linear motor, or a belt drive or chain drive, etc. The power system 30 may be selected according to different needs. The present invention does not impose any particular limitation.

[0041] In one embodiment, a soft mattress of appropriate size can be matched on the lumbar support plate 401 and the torso support plate 10 of the back-lifting mechanism 40, respectively. The mattress can be fixed by sticking Velcro on the lumbar support plate 401 and the torso support plate 10 to prevent the mattress from slipping during getting out of bed. A groove can also be machined on the support plate to fix the Velcro on the support plate, which is more reliable and does not require regular inspection to see if the Velcro needs to be re-fixed. In addition to using Velcro to fix the mattress, a medical stainless steel hook can also be used on the mattress to fix it in the locking groove of the support plate.

[0042] In summary, the present invention proposes a device for getting out of bed, which combines plate-type transportation and track-type transportation, rotates smoothly during movement, and maintains sufficient structural strength to bear the weight of the bedridden person. The combination of plate-type and track-type structures designed in this way does not require additional manual intervention or a complex control system. The angle adjustment can be automatically completed only through the clever coordination of the mechanical structure, providing the bedridden person with a more comfortable and safe shifting experience. The linkage relationship between the backrest and each support plate unit ensures the coordination of the movement, making the entire shifting process smooth and natural, fully reflecting the innovative considerations of the present invention in terms of human-computer interaction.
