Description

Technical Field

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

[0002] Hospital beds, as indispensable equipment in hospitals, play a vital role in patient rest and treatment. However, existing hospital beds have significant limitations: on the one hand, most beds only allow for the adjustment of the backrest to meet the basic needs of patients sitting up or lying down, but cannot rotate the entire bed board forward, backward, or side to side. In actual medical care, there are many needs for rotating the entire bed board, such as helping long-term bedridden patients change position to prevent bedsores, or adjusting the patient's posture during examinations and treatments to improve treatment effectiveness and comfort. Existing hospital beds cannot meet these needs.

[0003] Due to structural design limitations, existing hospital beds cannot be rotated forward, backward, left, or right as a whole, causing many inconveniences to medical and nursing work. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a new type of medical bed, which solves the problem that the existing medical beds cannot achieve the overall front-to-back and left-to-right flipping of the bed board.

[0005] According to an embodiment of the present invention, a novel medical bed includes a bed frame, which comprises a base frame, a lifting frame, and a movable frame. The lifting frame is located on the upper side of the base frame, and the movable frame is located on the upper side of the lifting frame. The movable frame is used to place a mattress. A first drive unit includes a first drive member and a second drive member, which are respectively disposed at both ends of the base frame. The tops of the first drive member and the second drive member are movably connected to both ends of the lifting frame. The first drive member and the second drive member are linked to drive the lifting frame to rise and fall and to rotate along its length direction. The second drive member is used to drive the lifting frame to rotate along its width direction. A second drive unit includes a third drive member and a fourth drive member, which are disposed on the lifting frame. The other ends of the third drive member and the fourth drive member are connected to the movable frame. The third drive member and the fourth drive member are used to adjust the angle of the movable frame.

[0006] Compared to existing technologies, this invention has the following advantages: By combining the linkage and independent action of the two driving components of the first driving unit, it can achieve both the lifting and lowering of the lifting frame, as well as the forward and backward, and left and right flipping, resulting in a high degree of functional integration. The two driving components of the second driving unit focus on adjusting the angle of the movable frame, coordinating with the flipping action of the lifting frame. In the first driving unit, when the first and second driving components are linked, they can drive the lifting frame to lift or flip along its length. Since the mattress is placed on the movable frame, the lifting and lowering or the flipping along its length will cause the movable frame and the mattress to move synchronously, which is equivalent to achieving the overall lifting and lowering or forward and backward flipping of the bed board. The second driving component can independently drive the lifting frame to flip along its width, which will also cause the movable frame and the mattress to flip accordingly, thus achieving the overall left and right flipping of the bed board. This meets the needs of long-term bedridden patients to change their position forward and backward, prevent bedsores, or adjust their posture forward, backward, left, and right during treatment and examination.

[0030] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 8 As shown, this embodiment of the invention proposes a novel medical bed, including a bed frame, which includes a base frame 10, a lifting frame 12, and a movable frame 40. The lifting frame 12 is located on the upper side of the base frame 10, and the movable frame 40 is located on the upper side of the lifting frame 12. The movable frame 40 is used to place a mattress. A first drive unit includes a first drive component and a second drive component, which are respectively disposed at both ends of the base frame 10. The tops of the first drive component and the second drive component are movably connected to both ends of the lifting frame 12. The first drive component and the second drive component are linked to drive the lifting frame 12 to rise and fall and to rotate along its length direction. The second drive component is used to drive the lifting frame 12 to rotate along its width direction. A second drive unit includes a third drive component and a fourth drive component, which are disposed on the lifting frame 12. The other ends of the third drive component and the fourth drive component are connected to the movable frame 40. The third drive component and the fourth drive component are used to adjust the angle of the movable frame 40.

[0032] The detailed working process of this embodiment is as follows: The two driving components of the first drive unit combine linkage and independent action, which can realize the lifting and lowering of the lifting frame 12, and can also complete the forward and backward and left and right flipping respectively, with a high degree of functional integration; the two driving components of the second drive unit focus on the angle adjustment of the movable frame 40, which cooperates with the flipping action of the lifting frame 12; in the first drive unit, when the first driving component and the second driving component are linked, they can drive the lifting frame 12 to lift or flip along its length. Since the movable frame 40 is located on the lifting frame 12 and a mattress is placed on it, the lifting and lowering or the flipping along its length will drive the movable frame 40 and the mattress to move synchronously, which is equivalent to realizing the overall lifting and lowering or forward and backward flipping of the bed board 30. The second driving component can independently drive the lifting frame 12 to flip along its width, which will also drive the movable frame 40 and the mattress to flip accordingly, that is, realize the overall left and right flipping of the bed board 30, so as to meet the needs of helping long-term bedridden patients change their body position forward and backward, prevent bedsores, or adjust their forward, backward and left and right postures during treatment and examination.

[0033] The bed frame is divided into three layers: base frame 10, lifting frame 12, and movable frame 40. The functions of each layer are clearly defined and the connection relationship is clear. The layers are connected in an orderly manner through drive units.

[0034] To prevent patients from falling off the bed, adjustable guardrails are installed on both sides of the lifting frame 12. When the patient is resting in bed, or when the bed is being turned over or adjusted in height, the guardrails are raised and locked, forming a solid barrier on both sides of the bed to prevent accidental displacement caused by the patient turning over, limb movement, or bed tilting, thus physically cutting off the path of falling.

[0035] like Figure 6 and 8 As shown, the first driving component includes a first lifting source 50 disposed at one end of the base frame 10, and a third top plate 501 disposed on the top of the first lifting source 50. Third rollers 502 are rotatably disposed on both sides of the third top plate 501. A follower frame 53 is fixedly disposed at one end of the lifting frame 12. A sub-frame 56 is hinged inside the follower frame 53. Two third slide rails 561 are symmetrically disposed inside the sub-frame 56. The two third rollers 502 are respectively located in the corresponding third slide rails 561.

[0036] The detailed working process of this embodiment is as follows: the first lifting source 50 serves as a power output component, providing the power foundation for the entire driving process; the third top plate 501 serves to connect the first lifting source 50 and the third roller 502.

[0037] When the first lifting source 50 operates, it drives the third top plate 501 and the third roller 502 to move. Since the third roller 502 is located within the third slide rail 561 of the sub-frame 56, and the sub-frame 56 is hinged to the follower frame 53, which is fixed to one end of the lifting frame 12, this connection allows the power of the first lifting source 50 to be efficiently transmitted to the lifting frame 12. When driving the lifting frame 12 to rise and fall, the third roller 502 slides smoothly within the third slide rail 561, ensuring smoothness of the lifting process. When driving the lifting frame 12 to rotate along its length, the relative movement of the third roller 502 and the third slide rail 561, combined with the hinged structure of the sub-frame 56 and the follower frame 53, flexibly adapts to the rotational movement of the lifting frame 12, reducing jamming and resistance during movement.

[0038] In this embodiment, the first lifting source 50 adopts a lifting motor. In other embodiments, a suitable lifting device can be flexibly selected according to the actual application scenario.

[0039] like Figure 6 and 7 As shown, the second driving component includes a second lifting source 51 and a third lifting source 52 mounted on the base frame 10. The second lifting source 51 and the third lifting source 52 are located on both sides of the base frame 10 away from the end of the first lifting source 50. The end of the lifting frame 12 away from the follower frame 53 is hinged to the active frame 57. The top of the second lifting source 51 is hinged to the active frame 57, and the top of the third lifting source 52 is movably connected to the active frame 57.

[0040] like Figure 7 As shown, the active frame 57 includes a fifth frame 54 and a sixth frame 55 fixedly connected to the fifth frame 54. The top of the second lifting source 51 is provided with a first top plate 511, and the two sides of the first top plate 511 are respectively hinged to the fifth frame 54.

[0041] like Figure 7 As shown, two second slide rails 551 are symmetrically arranged inside the sixth frame 55, and a second top plate 521 is provided on the top of the third lifting source 52. Second rollers 522 are rotatably arranged on both sides of the second top plate 521, and the two second rollers 522 are respectively located in the corresponding second slide rails 551.

[0042] The detailed working process of this embodiment is as follows: The fifth frame 54 is specifically designed to be hinged to the first top plate 511 at the top of the second lifting source 51. Utilizing the characteristics of the hinge structure, relative rotation between the second lifting source 51 and the active frame 57 is allowed, perfectly adapting to the change in the connection angle between the two during the flipping process of the lifting frame 12. The sixth frame 55 provides a stable support point for the movable connection at the top of the third lifting source 52.

[0043] When the second lifting source 51 and the third lifting source 52 perform differentiated actions (driving the lifting frame 12 to rotate along the width direction), the hinged connection between the fifth frame 54 and the second lifting source 51 provides a stable rotational fulcrum for the rotation of the lifting frame 12, while the movable connection between the sixth frame 55 and the third lifting source 52 can freely adjust its position with the rotation action. The two work together to make the rotation of the lifting frame 12 along the width direction smoother and the angle adjustment more precise. At the same time, when the lifting frame 12 is raised or lowered or rotated along the length direction in conjunction with the first driving component, this refined connection structure can also better adapt to the force changes of the overall action, improving the coordination of the entire drive system.

[0044] When the lifting frame 12 rotates along its width, the sixth frame 55 rotates with it. At this time, the relative angle and position of the third lifting source 52 and the sixth frame 55 change. The rolling engagement of the second roller 522 within the second slide rail 551 flexibly adapts to this change, allowing for relative displacement and angle adjustment between the two, ensuring that the third lifting source 52 always provides effective support and driving force to the lifting frame 12. Furthermore, when the lifting frame 12 is raised, lowered, or rotated along its length, rotation along its length can be achieved because one end of the lifting frame 12 is hinged to the drive frame 57. Simultaneously, the rolling contact between the roller and the slide rail results in less wear compared to sliding contact, and the slide rail guides and protects the roller, reducing the impact of external impurities on moving parts, extending component lifespan, and reducing maintenance frequency and costs.

[0045] In this embodiment, the second lifting source 51 and the third lifting source 52 are lifting motors. In other embodiments, a suitable lifting device can be flexibly selected according to the actual application scenario.

[0046] like Figure 4 As shown, the movable frame 40 includes a back panel 41, a second frame 42, a thigh plate 43, and a lower leg plate 44, and the back panel 41, the second frame 42, the thigh plate 43, and the lower leg plate 44 are hinged in sequence. A detachable bed board 30 is provided on the back panel 41, the second frame 42, the thigh plate 43, and the lower leg plate 44. The second frame 42 is fixedly mounted on the lifting frame 12.

[0047] The detailed working process of this embodiment is as follows: the back plate 41, thigh plate 43, and calf plate 44 correspond to the back, thigh, and calf of the human body, respectively. By rotating the hinge point, the angle of each part can be adjusted individually.

[0048] The second frame 42 serves as a fixed base to connect the lifting frame 12, providing stable support for the adjustment of other sections, ensuring the coordination of the movement of each component, and preventing overall swaying.

[0049] The removable bed board 30 design simplifies the cleaning and replacement process. In medical environments, the bed board 30 is prone to stains or germs. The removable structure allows for individual removal for cleaning and disinfection, or even replacement with a new bed board 30, reducing the risk of cross-infection.

[0050] like Figure 4 As shown, the third driving component includes a first telescopic source 13 fixedly mounted on the lifting frame 12. A rotating shaft 132 is rotatably mounted on the lifting frame 12. The rotating shaft 132 is located on the lower side of the back plate 41. A driving arm 131 is fixedly mounted on the rotating shaft 132. The output end of the first telescopic source 13 is hinged to the end of the driving arm 131 away from the rotating shaft 132. Control arms 133 are fixedly mounted at both ends of the rotating shaft 132. A connecting rod 134 is connected to the end of the two control arms 133 away from the rotating shaft 132. A first roller 135 is provided at both ends of the connecting rod 134. A first slide rail 411 is mirror-mounted on the back plate 41. The two first rollers 135 are respectively located in the corresponding first slide rail 411.

[0051] The detailed working process of this embodiment is as follows: the third driving component achieves precise adjustment of the angle of the back plate 41 through the coordinated cooperation of the first telescopic source 13, the rotating shaft 132, the driving arm 131, the control arm 133, the connecting rod 134, the first roller 135 and the first slide rail 411.

[0052] When the first telescopic source 13 extends or retracts, its output end pushes the drive arm 131 to rotate around the rotating shaft 132. The rotation of the rotating shaft 132 synchronously drives the control arms 133 at both ends to move. The control arm 133 drives the first roller 135 to roll in the first slide rail 411 of the back plate 41 through the connecting rod 134. Finally, it drives the back plate 41 to rotate around the hinge point to adjust the angle, converting the linear motion of the first telescopic source 13 into the rotational motion of the back plate 41.

[0053] Two control arms 133 are mirror images of each other at both ends of the rotating shaft 132 and are connected by a connecting rod 134 to form a balanced force structure, ensuring that the driving force at both ends of the rotating shaft 132 is evenly transmitted to the back plate 41 when it rotates. The first roller 135 is embedded in the first slide rail 411 of the back plate 41. The rolling action not only reduces the frictional resistance during the adjustment process, but also limits the movement trajectory of the back plate 41 through the guiding effect of the slide rail, making the angle adjustment of the back plate 41 more stable and precise, and avoiding deviation or shaking.

[0054] In this embodiment, the first telescopic source 13 adopts a push rod motor. In other embodiments, a suitable telescopic device can be flexibly selected according to the actual application scenario.

[0055] like Figure 4 As shown, the fourth driving component includes a second telescopic source 14 disposed on the lifting frame 12, and the output end of the second telescopic source 14 is hinged to the thigh plate 43.

[0056] The detailed working process of this embodiment is as follows: When the second telescopic source 14 extends or retracts, the linear motion at its output end can be directly converted into the rotational motion of the thigh plate 43 around the hinge point; the extension and retraction stroke of the second telescopic source 14 determines the rotation angle range of the thigh plate 43. By reasonably designing the parameters of the telescopic source, the needs of patients in different scenarios can be met—such as adjusting the thigh plate 43 to a horizontal state when the patient is resting in bed, appropriately raising it to bend the leg during rehabilitation training, or adjusting the angle during nursing care to facilitate dressing changes, examinations, etc. In addition, the direct drive method makes the angle adjustment process smoother, avoiding jamming or shaking caused by transmission gaps, and improving the patient's physical comfort.

[0057] In this embodiment, the second telescopic source 14 adopts a push rod motor. In other embodiments, a suitable telescopic device can be flexibly selected according to the actual application scenario.

[0058] like Figure 4 and Figure 5 As shown, the lower leg plate 44 is symmetrically provided with adjusting arms 11 at the end away from the hinge point, and the ends of the two adjusting arms 11 away from the lower leg plate 44 are hinged to the lifting frame 12.

[0059] The detailed working process of this embodiment is as follows: The hinge structure between the adjusting arm 11 and the lifting frame 12 provides a flexible interface for the linkage between the calf plate 44 and other components of the bed. When the thigh plate 43 adjusts its angle under the action of the fourth driving component, the calf plate 44 is linked with the hinge point of the thigh plate 43, and at the same time, the adjusting arm 11 rotates around the hinge point of the lifting frame 12, forming a coordinated action chain of "thigh plate 43-calf plate 44-adjusting arm 11", ensuring that the leg posture always conforms to the human physiological curve.

[0060] The adjusting arm 11 is an existing component, and it actually has a wavy groove. When the lower leg plate 44 moves with the thigh plate 43 or needs to be adjusted independently, the slide rail is pulled out, which drives the locking pin to move in the wavy groove. Each peak and trough of the wavy groove forms a positioning point. By engaging different positioning points with the locking pin, the lower leg plate 44 can be fixed at the corresponding angle to meet the needs of patients in different scenarios. This is only an introduction to the features of the adjusting arm 11, which meets the usage requirements; the specific structure is common knowledge and will not be described in detail.

[0061] like Figure 1 and Figure 3 As shown, casters 20 and braking systems 21 are provided at the four corners of the bottom of the base frame 10. The braking system 21 is linked with each caster 20.

[0062] The detailed working process of this embodiment is as follows: The casters 20 can rotate freely 360 degrees. Combined with the symmetrical layout of the four corners of the base frame 10, the bed can be flexibly turned and moved in narrow ward passages, corridors, or treatment rooms, greatly reducing the difficulty of moving patients. Whether it is an emergency transfer of critically ill patients or a routine adjustment of the bed position for convenient care, medical staff can achieve precise movement with less effort, improving work efficiency.

[0063] The linkage design between the braking system 21 and each caster wheel 20 is the core of ensuring stability. When the bed needs to be fixed in a specific position (such as during treatment, examination, or patient rest), operating the braking system 21 can simultaneously lock all caster wheels 20, preventing accidental movement of the bed due to external forces (such as patient turning over or collisions). Compared to a braking structure that controls each wheel individually, the linkage design simplifies the operation process. Medical staff only need to perform a single operation to lock all wheels, saving time and ensuring the reliability of the fixation—preventing bed displacement due to individual wheels not being locked, fundamentally eliminating safety hazards.

[0064] Braking linkage is a technology already existing in this field and will not be described in detail here.

[0065] The implementation principle of this application's embodiments is as follows:

[0066] The lifting function is mainly achieved through the linkage of the first driving component and the second driving component of the first driving unit. When the first lifting source 50, the second lifting source 51 and the third lifting source 52 extend or shorten synchronously, the two ends of the lifting frame 12 are subjected to synchronous upward or downward forces, thereby realizing the overall lifting.

[0067] Flipping along the length direction – Flipping along the length direction is driven by the first and second drive components of the first drive unit. The length direction is the head-to-tail direction of the bed. When flipping is required, the first and second drive components generate height. Since the third roller 502 of the first drive component slides in the third slide rail 561, it can adapt to the angle change of the lifting frame 12. The hinge between the second lifting source 51 and the active frame 57 in the second drive component, and the sliding of the second roller 522 of the third lifting source 52 in the second slide rail 551 can also cooperate with the angle adjustment. The lifting frame 12 rotates with its central axis in the length direction as a virtual axis, thereby realizing flipping along the length direction.

[0068] Flipping along the width direction – Flipping along the width direction is mainly driven independently by the second drive unit, which is the left-right direction of the bed. A height difference is created between the second lifting source 51 and the third lifting source 52 through the second drive unit; the second lifting source 51 extends and the third lifting source 52 shortens. Since the second lifting source 51 is hinged to the fifth frame 54 of the active frame 57, the second roller 522 of the third lifting source 52 slides in the second slide rail 551 of the sixth frame 55. The active frame 57 is connected to the other end of the lifting frame 12, so that a height difference is created between the left and right sides of one end of the lifting frame 12. At this time, the lifting frame 12 rotates with its central axis in the width direction as a virtual axis, realizing flipping along the width direction.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
