Technical Field

[0001] This utility model belongs to the field of rehabilitation bed technology, specifically relating to a lower limb rehabilitation device for patients with limited mobility. Background Technology

[0002] While existing electric hospital beds offer adjustable bed frame angles and some integrate vibration modules, they suffer from significant limitations in lower limb muscle traction rehabilitation scenarios. Most vibration modules operate at a single frequency, failing to coordinate with bed angle changes to create a "self-weight pressure + alternating vibration" traction effect. Furthermore, the lack of synergy between angle adjustment and vibration function hinders precise traction of different lower limb muscle groups, particularly for patients with limited mobility, sub-critical conditions, or those in the early stages of rehabilitation. This makes targeted rehabilitation less effective and preventative intervention to prevent muscle atrophy and early intermuscular venous thrombosis. Therefore, a lower limb rehabilitation device specifically designed for patients with limited mobility is needed to address these technical challenges. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example Please see Figure 1-8 This embodiment provides the following technical solution: a lower limb rehabilitation device for patients with limited mobility, including an electric hospital bed and a vibration host. The vibration host is installed at one end of the electric hospital bed via a connecting frame. The electric hospital bed includes a base frame 1, a bed frame 2, and a baffle 3. The base frame 1 is provided with casters. The bed frame 2 is located above the base frame 1. Baffles 3 are provided around the bed frame 2. The vibration host is fixedly connected to the inside of the right baffle 3 via the connecting frame.

[0017] A fixed bed frame 5 is fixedly connected to the right side of the bed frame 2, and a movable bed frame 6 is movably connected to the left side of the bed frame 2. The movable bed frame 6 and the fixed bed frame 5 are rotatably connected on the opposite side through a hinge 7. With the fixed bed frame 5 and the movable bed frame 6, the posture of the patient's upper body can be adjusted while supporting the patient's body.

[0018] A second telescopic assembly is provided between the fixed bed frame 5 and the movable bed frame 6 to adjust the posture of the patient's upper body. The second telescopic assembly includes a second push rod 8. The fixed end of the second push rod 8 is hinged to the movable bed frame 6, and the movable end of the second push rod 8 is hinged to a support plate 9. The other end of the support plate 9 is hinged to the fixed bed frame 5. During the extension or retraction of the second push rod 8, the movable bed frame 6 can be rotated around the hinge pin 7, changing the angle between the movable bed frame 6 and the fixed bed frame 5. This allows the patient to lie on the bed in a sitting or semi-reclining position, which not only improves the patient's usability but also prevents the upper body from slipping by raising the back, ensuring that the patient's weight is effectively transferred to the legs and the vibration host.

[0019] First telescopic components 4 are provided between the left and right ends of the bed frame 2 and the base frame 1, used to tilt the bed frame 2 to apply the patient's weight onto the vibration host. The first telescopic component 4 includes a first push rod 41, a fixed rod 44, and a hinge rod 45. The first push rod 41 is located below the base frame 1, and the fixed end of the first push rod 41 is hinged to the base frame 1. The telescopic end of the first push rod 41 is hinged to a drive rod 42. The other end of the drive rod 42 is fixedly connected to a rotating shaft 43, which is rotatably connected to the top of the base frame 1. Fixed rods 44 are fixedly connected to both sides of the rotating shaft 43, and the other end of the fixed rod 44 is hinged to a hinge rod 45. The other end of the hinge rod 45 is hinged to the movable bed frame 6. When the first push rod 41 on the left extends and the first push rod 41 on the right shortens, the left side of the bed frame 2 can be raised and the right side of the bed frame 2 can be pressed down, so that the bed frame 2 can form a tilted state with the left side higher and the right side lower on the base frame 1. This can guide patients with limited mobility to apply pressure to the vibration host by their own weight. Combined with the alternating vibration of the vibration host, it forms a dynamic traction on the lower limb muscles, which solves the problems of existing equipment being weak in rehabilitation and targeted, and unable to effectively prevent muscle atrophy for patients with limited mobility, sub-critical patients, and patients in the early stage of rehabilitation.

[0020] The vibration host includes a mounting shell 10, a vibration shell 12, and a vibration mechanism 16. A mounting frame 11 is fixedly connected inside the mounting shell 10. The vibration shell 12 is movably sleeved on the left end of the mounting shell 10. The vibration shell 12 and the mounting shell 10 are rotatably connected through a connecting mechanism. A vibration frame 15 is fixedly connected inside the vibration shell 12. The vibration mechanism 16 is mounted on the mounting frame 11 and is used to make the vibration shell 12 swing back and forth around the connecting mechanism. By setting the connecting mechanism and the vibration mechanism 16, the vibration shell 12 can generate a reciprocating vibration force. When a patient with limited mobility relies on their own weight to act on the vibration shell 12, it can perform muscle traction rehabilitation on the lower limbs of the patient with limited mobility.

[0021] As shown in the figure, there are two connecting mechanisms. The two connecting mechanisms are respectively located between the middle of the left and right sides of the mounting frame 11 and the vibration frame 15. The connecting mechanism includes a fixed seat 13 and a movable seat 14. The fixed seat 13 is fixedly connected to the mounting frame 11, and the movable seat 14 is fixedly connected to the vibration shell 12. The other end of the movable seat 14 and the fixed seat 13 are rotatably connected by a pin, so that the movable seat 14 can rotate on the fixed seat 13 with the pin as the center, thereby enabling the vibration shell 12 to rotate on the mounting shell 10 with the pin as the center.

[0022] The vibration mechanism 16 includes a servo motor 161, a drive shaft 163, and a cam 164. The servo motor 161 is fixedly connected to the mounting bracket 11 and electrically connected to a servo motor controller 162 on the mounting bracket 11. The drive shaft 163 is rotatably connected to the mounting bracket 11 via a bearing seat. One end of the drive shaft 163 is drively connected to the output shaft of the servo motor 161, and the other end of the drive shaft 163 is fixedly connected to the cam 164. The other end of the cam 164 is hinged to a hinge seat 165. The other end of 5 is fixedly connected to the mounting bracket 11. As the cam 164 rotates, the cam 164 will continuously apply force to the vibration frame 15. Since the vibration frame 15 is rotatably connected to the pin on the movable seat 14 and the fixed seat 13, this force will cause the vibration frame 15 to swing around the pin. At the same time, since the vibration frame 15 and the vibration shell 12 are fixedly connected, the swing of the vibration frame 15 will drive the vibration shell 12 to reciprocate relative to the mounting shell 10, thereby producing a vibration effect for lower limb rehabilitation treatment.

[0023] It also includes a power supply component for controlling the power supply to the servo motor controller 162. The power supply component includes a power interface 17 and a power switch 18. The power interface 17 is fixedly installed on the outside of the mounting housing 10 for connecting to an external power source. The power switch 18 is connected in series between the power interface 17 and the main power input terminal of the servo motor controller 162, so that the vibration host can be connected to the power supply equipment through the external power cord plugged into the power interface 17, thereby controlling the start and stop of the vibration host through the power switch 18.

[0024] It also includes a wired control component for sending control commands to the servo motor controller 162. The wired control component includes a wired remote control interface 19 and a wired remote control. The wired remote control interface 19 is fixed on the outside of the mounting housing 10. The wired remote control interface is electrically connected to the control signal input terminal of the servo motor controller 162. The wired remote control is detachably connected to the wired remote control interface 19 through its own locking plug wire. The locking plug on the wired remote control can be inserted into the wired remote control interface 19 on the side of the mounting housing 10, making it convenient for the patient to operate the vibration host through the wired remote control.

[0025] The working principle of this utility model is as follows: When in use, the patient lies flat on the bed frame 2, the fixed bed frame 5, and the movable bed frame 6, with the patient's feet pressed against the surface of the vibration shell 12. Then, the power switch 18 of the vibration host is turned on, and with the help of a wired remote control, the servo motor controller 162 transmits control signals to the servo motor 161 through the buttons on the wired remote control. The servo motor 161 rotates, driving the drive shaft 163 and the cam 164 to rotate. As the cam 164 rotates, the cam 164 will continuously apply force to the vibration frame 15. Since the vibration frame 15 is rotatably connected to the pin on the movable seat 14 and the fixed seat 13, this force will cause the vibration frame 15 to swing around the pin. At the same time, since the vibration frame 15 and the vibration shell 12 are fixedly connected, the swing of the vibration frame 15 will drive the vibration shell 12 to reciprocate relative to the mounting shell 10, thereby producing a vibration effect for lower limb rehabilitation treatment. When it is necessary to adjust the overall tilt angle of the bed frame 2, the first push rod 41 on the left side is extended and the first push rod 41 on the right side is retracted by using the control button on the electric hospital bed. With the cooperation of the fixed rod 44, the rotating shaft 43 and the hinge rod 45, the left end of the bed frame 2 is gradually raised and the right end of the bed frame 2 is gradually pressed down, so that the bed frame 2 can form a tilt state with the left side higher and the right side lower on the base frame 1. This allows patients with limited mobility to rely on their own weight to act on the vibration host. Combined with the alternating vibration of the vibration host, dynamic traction is formed on the muscles of the lower limbs. When it is necessary to adjust the patient's upper body posture, the second push rod 8 can be extended by using the control button on the electric hospital bed. This allows the movable bed frame 6 to rotate around the hinge 7, thereby gradually raising the patient's upper body. Raising the patient's upper body avoids the pressure on the lower limbs from the back when lying flat, which would otherwise cause the pressure on the vibrating host to be dispersed. At the same time, raising the upper body can reduce the dizziness caused by the patient standing / tilting the bed, ensuring that the patient's weight is effectively transmitted to the vibrating host through the lower limbs in a stable posture.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
