Description

Technical Field

[0001] This utility model relates to the field of medical bed technology, and in particular to an electric standing bed. Background Technology

[0002] The medical standing bed is a key piece of equipment in rehabilitation medicine that helps patients transition from a supine to a standing position. Its core function lies in enabling progressive rehabilitation training through adjustments to the bed's tilt angle. This adjustment not only helps patients gradually adapt to changes in gravity and prevent orthostatic hypotension, but also strengthens the lower limb and back muscles, improves cardiopulmonary function and blood circulation, and effectively prevents complications such as osteoporosis and muscle atrophy. In clinical applications, training typically begins at 15°-30° and gradually increases to a safe angle of approximately 80°.

[0003] When the bed approaches or reaches its maximum tilt angle (such as 90°), the overall center of gravity of the patient and the bed will shift significantly upward, while the supporting area of ​​the base will decrease relatively, resulting in a sharp decline in stability and making it very easy for the bed to tip over, causing injury to the patient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electric standing hospital bed, which solves the problem that existing standing beds are prone to instability and tipping over when the bed body tilts at a large angle.

[0005] According to an embodiment of this utility model, an electric standing hospital bed includes a frame, a bed body, a bed board, a first motor, and a counterweight box. The bottom of the frame is provided with casters, one end of the top of the frame is hinged to one end of the bed body, and the other end of the frame abuts against the other end of the bed body. Both ends of the bed body are provided with the bed board. There is at least one first motor. The bottom of the frame is provided with a first connecting plate, and the first motor is hinged to the first connecting plate. The output end of the first motor is hinged to one end of the bottom of the bed body. The bottom of the frame is provided with an mounting strip, and the counterweight box is detachably mounted on the bottom of the frame and away from the hinge end between the frame and the bed body via the mounting strip.

[0006] Compared with existing technologies, this utility model has the following advantages: By hinged one end of the frame to one end of the bed, the output end of the first motor hinged to the first connecting plate at the bottom of the frame extends and pushes the bed to rotate around its hinged end, thereby allowing the bed to tilt at different angles relative to the frame. This makes it convenient for medical staff to place the patient's body at different tilt angles for rehabilitation training according to the patient's rehabilitation progress. When the tilt angle of the bed is too large, the counterweight box plays a counterweight role, keeping the center of the standing bed always near the middle, making the standing bed stable enough during use. The shaking caused by the patient's movements during rehabilitation training will not cause the standing bed to tip over or shake, thus allowing the patient to maintain a stable mindset and ensure safety when performing rehabilitation training on a stable bed.

[0007] Furthermore, there are two first motors, and two first connecting plates are symmetrically provided at the bottom of the frame. Both first motors are hinged to the corresponding first connecting plates, and the output ends of both first motors are hinged to the bottom of the bed.

[0008] Furthermore, there are two mounting strips, which are symmetrically and detachably connected to both sides of the counterweight box. One end of each mounting strip is fixedly connected to the corresponding first connecting plate, and the other end of each mounting strip is fixedly connected to the frame.

[0009] Furthermore, the counterweight box includes a box body and a cover, with a wing plate extending outward from the top of the box body, and the cover and the wing plate being detachably connected.

[0010] Furthermore, it also includes a second motor, a first receiving groove is provided at one end of the bed, a back plate is hingedly provided in the first receiving groove, a second connecting plate is provided at the bottom of the bed, the second motor is hinged to the second connecting plate, and the output end of the second motor is hinged to the back plate.

[0011] Furthermore, it also includes a third motor, a second receiving groove is provided on the top of the bed, a first leg plate is hinged in the second receiving groove, a second leg plate is hinged on the first leg plate, a third connecting plate is provided at the bottom of the bed, the third motor is hinged to the third connecting plate, and the output end of the third motor is hinged to the first leg plate.

[0012] Furthermore, it also includes a fence, which consists of two pieces. The two ends of the opposite sides of the two bed boards are provided with sliding grooves. Each end of the fence is provided with a sliding strip, which is slidably installed in the sliding groove. Each bed board is provided with a limiting component to restrict the sliding strip from sliding in the sliding groove.

[0013] Furthermore, each limiting component includes: a limiting sleeve and a sliding column. The limiting sleeve is horizontally installed on the bed board with one end extending into the sliding groove. The limiting sleeve has an opening on the side facing the slide bar. The sliding column is slidably installed in the limiting sleeve and has a limiting post on the side facing the opening of the limiting sleeve.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3As shown in the figure, this utility model embodiment proposes an electric standing hospital bed, including a frame 1, a bed body 2, a bed board 4, a first motor 5, and a counterweight box 7. The bottom of the frame 1 is equipped with casters 3, which are existing technology and have a braking function. One end of the top of the frame 1 is hinged to one end of the bed body 2, and the other end of the frame 1 abuts against the other end of the bed body 2. Both ends of the bed body 2 are equipped with the bed board 4. There is at least one first motor 5. The bottom of the frame 1 is equipped with a first connecting plate 6, and the first motor 5 is hinged to the first connecting plate 6. The output end of the first motor 5 is hinged to one end of the bottom of the bed body 2. The bottom of the frame 1 is equipped with a mounting strip 8. The counterweight box 7 is detachably mounted on the bottom of the frame 1 and away from the hinge end between the frame 1 and the bed body 2 via the mounting strip 8. This hospital bed is moved by the casters 3 at the bottom of the frame 1. When performing standing rehabilitation training on the patient, the first motor 5 is activated. Specifically, the first motor 5 can be an electric push rod. The output end of the first motor 5 pushes the bed 2 to rotate around the hinge end with the frame 1. The bed 2 tilts relative to the horizontal frame 1 to a predetermined angle. The patient lies on the bed 2 with their feet on the bed board 4 near their feet for rehabilitation training.

[0025] In this embodiment, the output end of the first motor 5 is connected to the bottom of the bed body 2 near the end that is hinged to the frame 1. When the bed body 2 is pushed and rotated by the first motor 5 to a degree close to 90 degrees, the center of gravity of the entire bed shifts. The patient's movements during rehabilitation training exacerbate the instability. By pre-filling the counterweight box 7 with counterweight sand, the weight of the counterweight box 7 is increased, and the counterweight box 7 adjusts the center of gravity of the standing bed, thereby improving the overall stability of the standing bed, preventing tipping, and ensuring the safety of the patient during rehabilitation training.

[0026] like Figure 2 As shown, furthermore, there are two first motors 5. Two first connecting plates 6 are symmetrically arranged at the bottom of the frame 1. Both first motors 5 are hinged to their corresponding first connecting plates 6, and the output ends of both first motors 5 are hinged to the bottom of the bed 2. In this embodiment, there are two first motors 5, each mounted on one side of the frame 1 via the first connecting plates 6. The two first motors 5 start synchronously, simultaneously generating a pushing force on both sides of the bed 2, causing the bed 2 to rotate around its hinged ends. By controlling the extension length of the output ends of the first motors 5, the bed 2 can be positioned at different tilt angles. The two first motors 5 pushing the bed 2 from both sides of the frame 1 make the bed 2 more stable during rotation and allow the output ends of the first motors 5 to provide stable support to the bed 2.

[0027] Furthermore, there are two mounting strips 8, which are symmetrically and detachably connected to both sides of the counterweight box 7. One end of each mounting strip 8 is fixedly connected to the corresponding first connecting plate 6, and the other end of each mounting strip 8 is fixedly connected to the frame 1. In this embodiment, one end of each mounting strip 8 is fixed to the bottom of one end of the frame 1, and the other end is fixed to the side of the first connecting plate 6 away from the first motor 5. The two mounting strips 8 form the installation space of the counterweight box 7, supporting the counterweight box 7. At the same time, one end of the mounting strip 8 abuts against the first connecting plate 6 to increase the support strength of the first connecting plate 6. The first motor 5 applies force to the first connecting plate 6, effectively preventing the first connecting plate 6 from deforming.

[0028] like Figure 4 As shown, the counterweight box 7 further includes a box body 701 and a cover 702. The cover 702 is detachably mounted on the top of the box body 701. A wing plate 703 extends outward from the top of the box body 701, and the cover 702 and the wing plate 703 are detachably connected. Specifically, the connection between the cover 702 and the wing plate 703 can be a screw connection or a bolt connection, or other methods that facilitate disassembly. By opening the cover 702, counterweight sand or other materials can be poured into the box body 701 to increase the overall weight of the counterweight box 7.

[0029] like Figure 2 and Figure 3 As shown, the bed also includes a second motor 9. A first receiving groove is provided at one end of the bed body 2, and a backplate 10 is hingedly mounted within the first receiving groove. A second connecting plate 11 is provided at the bottom of the bed body 2. The second motor 9 is hinged to the second connecting plate 11, and the output end of the second motor is hinged to the backplate 10. It should be noted that a crossbeam for supporting the backplate 10 is mounted at the bottom of the bed body 2. The output end of the second motor 9 is hinged to the middle of the backplate 10. When the patient is lying in bed, it is necessary to adjust the patient's posture. By activating the second motor 9, the output end of the second motor 9 drives the backplate 10 to rotate around its hinged end, causing it to tilt relative to the frame 1, thereby achieving the purpose of adjusting the patient's upper limb posture.

[0030] like Figure 2 and Figure 3As shown, the bed further includes a third motor 12. A second receiving groove is provided at the top of the bed body 2, and a first leg plate 13 is hingedly disposed within the second receiving groove. A second leg plate 14 is hingedly disposed on the first leg plate 13. A third connecting plate 15 is provided at the bottom of the bed body 2. The third motor 12 is hinged to the third connecting plate 15, and the output end of the third motor 12 is hinged to the first leg plate 13. By activating the third motor 12, the output end of the third motor 12 pushes the first leg plate 13 to rotate around its hinged end, causing the first leg plate 13 and the second leg plate 14 to form a triangular structure, supporting the patient's thigh and calf, thereby reducing the occurrence of lower extremity venous thrombosis and improving blood circulation. The second motor 9 and the third motor 12 can also be electric push rods.

[0031] like Figure 1 As shown, the system further includes a railing 16, which consists of two pieces. Each end of the two bed boards 4 has a sliding groove, and each end of each railing 16 has a sliding strip 17. The sliding strip 17 is slidably positioned within the sliding groove. Each bed board 4 has a limiting member to restrict the sliding strip 17 from sliding within the groove. The railing 16 serves a protective function, preventing the patient from falling off the bed when unattended. The limiting member can be a spring pin, and the corresponding sliding strip 17 has a hole for the spring pin to be inserted. Locking the sliding strip 17 within the sliding groove with a spring pin is existing technology. The railing 16 can be disassembled and installed by limiting and releasing the limiting member.

[0032] like Figure 5 and Figure 6 As shown, each limiting component further includes a limiting sleeve 18 and a sliding post 19. The limiting sleeve 18 is horizontally installed on the bed board 4 and one end of it extends into the sliding groove. The limiting sleeve 18 has an opening on the side facing the slide bar 17. The sliding post 19 is slidably installed in the limiting sleeve 18 and has a limiting post 20 on the side of the sliding post 19 facing the opening of the limiting sleeve 18. A spring 21 is connected between the sliding post 19 and the limiting sleeve 18. The slide bar 17 has a slot 22 for the limiting post 20 to be engaged. In this embodiment, when installing the fence 16, the slide bar 17 on the fence 16 slides into the groove. When the fence 16 is raised to the height of the limiting sleeve 18, the slide post 19 is pressed, causing the slide post 19 to move towards the spring 21, so that the limiting post 20 does not block the slide bar 17. When the slot 22 of the slide bar 17 is at the same height as the limiting post 20, the slide post 19 is released. The slide post 19 is reset under the push of the spring 21, and the limiting post 20 moves horizontally and engages in the slot 22 of the slide bar 17, thus completing the limiting of the fence 16. In this embodiment, the top of the slot 22 is arched, and when the limiting post 20 is engaged in the slot 22, it is located in the top area of ​​the arched shape of the slot 22.

[0033] like Figure 5As shown, the top of the slide bar 17 is triangular 23. To facilitate the installation of the fence 16, the limiting post 20 is cylindrical. During the upward movement of the slide bar 17 within the groove, the triangular structure 23 at the top of the slide bar 17 abuts against the limiting post 20, pushing the limiting post 20 towards the spring 21, thus preventing it from obstructing the upward movement of the slide bar 17. This continues until the slot 22 of the slide bar 17 rises to a position flush with the limiting post 20. Then, the limiting post 20, pushed by the spring 21, engages with the slot 22. Therefore, when installing the fence 16, it is unnecessary to press the slide post 19 to move it towards the spring 21, simplifying the installation process. Preferably, the triangular structure 23 at the top of the slide bar 17 is offset away from the spring 21. Alternatively, the limiting post 20 remains offset towards the side closer to the spring 21 in its normal state.

[0034] like Figure 2 As shown, further, a support column 24 is provided at the end of the frame 1 away from its hinge end, and a rubber pad 25 is provided on the top of the support column 24. The support column 24 supports the bottom of the bed 2, and the rubber pad 25 acts as a buffer during the tilting and leveling of the bed 2 to prevent the bottom of the bed 2 from rigidly colliding with the support column 24.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model 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 this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
