Description

Technical Field

[0001] This utility model relates to the field of medical assistive devices, specifically to a medical bed for assisting lower limb rehabilitation. Background Technology

[0002] Patients with chronic renal insufficiency require long-term hemodialysis (HD) treatment. Maintenance hemodialysis (MHD) patients, due to long-term dialysis, decreased cardiopulmonary function, and muscle strength, are prone to developing a sedentary lifestyle lacking exercise, leading to impaired aerobic metabolism, a significant risk factor for all-cause mortality in this population. Exercise rehabilitation not only improves dialysis efficiency but also significantly improves cardiopulmonary function, muscle strength (especially lower limb muscle strength), reduces inflammation, and improves quality of life in MHD patients. Exercise rehabilitation during hemodialysis typically involves using a recumbent pedaling device on the dialysis bed, three times a week for 30-60 minutes each time, completed two hours before dialysis.

[0003] Commercially available recumbent bicycles often lack a fixing device, leading to uneven force application during aerobic cycling exercises in a supine position. This can cause the bicycle to tilt, making it difficult to increase power, frequently resulting in treatment interruptions and affecting the therapeutic effect. Therefore, a rehabilitation therapy bed and bicycle integrated device suitable for supine patients has significant clinical importance and practical value.

[0004] Rehabilitation beds come in various structural forms. For example, the rehabilitation bed with leg muscle and joint rehabilitation function disclosed in Chinese patent document 202122042331.X imitates the normal walking or running movements of a person by pushing the pedal back and forth and up and down in an orderly manner. After fixing the patient's feet on the pedal, the patient's knee and ankle joints can be fully moved, so that the lower limb muscle groups can be exercised and the problem of calf muscle atrophy can be effectively alleviated.

[0005] For example, Chinese patent document 202120465204.8 discloses a rehabilitation medical bed for assisting in the rehabilitation of both legs. By setting up a movable seat, when the patient trains their legs in an inclined state, the movable seat can be rotated so that the movable seat is perpendicular to the movable bed. The patient can sit on the movable seat to train, thus ensuring comfort and improving safety when exercising the legs.

[0006] However, current rehabilitation beds typically require medical personnel to operate, resulting in a relatively limited training model. Furthermore, existing medical beds cannot meet the specific training needs of different patients or the same patient at different stages of rehabilitation. They also do not allow patients to adjust the position of the training equipment independently, leading to problems such as poor rehabilitation training status and high difficulty for patients as they need to adapt to the equipment. Utility Model Content

[0007] In order to at least partially address the shortcomings of the existing technology, the main objective of this utility model is to provide a medical bed for assisting lower limb rehabilitation that is simple in structure and highly practical.

The drive motor is mounted on the bed frame, and the worm wheel is mounted on the third bed board.

[0013] This solution utilizes the self-locking characteristic of the worm gear mechanism to keep the third bed board and the rehabilitation training equipment on it at the required angle.

[0014] Furthermore, the bed frame is equipped with a control box, which contains a control board and at least one button. The control board is connected to the drive motor, and the drive motor is turned on or off by pressing the button.

[0015] According to a specific embodiment of the present invention, an indicator plate is provided on the bed frame, and the indicator plate is located next to the third bed board; wherein, the indicator plate is provided with multiple scale lines for indicating the current angle of the third bed board.

[0016] Furthermore, the indicator panel is a transparent panel.

[0017] According to a specific embodiment of the present invention, a movable support frame is provided on the bed frame. When the first bed board is flipped to a predetermined position, it can be supported by the movable support frame and kept in the current predetermined position.

[0018] According to a specific embodiment of this utility model, the bed frame is also provided with multiple omnidirectional casters.

[0019] This utility model has the following beneficial effects: It provides a medical bed for assisting lower limb rehabilitation, which drives the third bed board to rotate through a rotary drive mechanism, thereby changing the position of the rehabilitation training equipment and making the rehabilitation training equipment more suitable for the needs of the usage scenario. It can meet the targeted training needs of different patients and different rehabilitation stages of the same patient, and has the advantages of simple structure and strong practicality.

[0026] Many specific details are set forth in the following description in conjunction with embodiments in order to provide a full understanding of the present invention. However, it should be understood that the following embodiments and detailed description are for illustrative purposes only and do not limit the scope of protection of the present invention.

[0027] The medical bed for assisting lower limb rehabilitation in the embodiment is as follows: Figure 1-3 As shown, it includes a bed 10 and rehabilitation training equipment 20; wherein, the rehabilitation training equipment 20 is, for example, a bicycle, but this embodiment is not limited to this; for example, the rehabilitation training equipment 20 can also be a movable pedal, which will not be listed here.

[0028] The bed frame 10 includes a bed frame 11 and a combined bed board 12 placed on the bed frame 11; wherein, the bed frame 11 includes a support frame 111, a bed board frame 112, side guardrails 113, headboard guardrails 114 and footboard guardrails 115; the support frame 111 is preferably provided with a plurality of omnidirectional casters 116 below it, and the omnidirectional casters 116 preferably have a locking function to realize the free movement and locking of the bed frame 10.

[0029] The bed frame 112 is preferably prefabricated as a single unit with the support frame 111; in other embodiments, the two can also be assembled as a single unit. The side rails 113, headboard rails 114, and footboard rails 115 are respectively installed at corresponding positions on the bed frame 112, as detailed in the following references. Figure 1-2 .

[0030] The modular bed board 12 includes a first bed board 121, a second bed board 122, and a third bed board 123, which are arranged sequentially along the length of the bed frame 11. The first bed board 121 provides back support and is rotatably mounted on the bed board frame 112, and can be flipped around the width of the bed frame 11. (See also...) Figure 2-3 The bed frame 112 is also provided with a movable support frame 117 for providing support and a knob 118 for adjusting the flip position of the first bed board 121. The back of the first bed board 121 is provided with multiple support grooves corresponding to different angle positions. When the first bed board 121 is flipped to the predetermined position, it can be supported in the corresponding support groove by the movable support frame 117, so that the first bed board 121 is kept in the current predetermined position.

[0031] The second bed board 122 is used to provide hip support and is fixedly mounted on the bed board frame 112; wherein, preferably, side guardrails 113 are provided on both sides of the bed board frame 112 to provide better protection for the patient; preferably, at least one side guardrail 113 is detachable to further improve practicality.

[0032] The third bed board 123 is used to mount the rehabilitation training equipment 20, and it is rotatably mounted on the bed board frame 112. The third bed board 123 can rotate under the drive of the rotation drive mechanism 30 to change the usage position of the rehabilitation training equipment 20 and to store the equipment under the third bed board 123. Further, the third bed board 123 is provided with a rotation shaft 124, which is arranged along the width direction of the bed frame 11. The rotation drive mechanism 30 can drive the third bed board 123 to rotate by driving the rotation shaft 124. In an optional embodiment, the rotation shaft 124 can also be arranged along the length direction of the bed frame 11.

[0033] The rehabilitation training equipment 20 is installed in the middle of the third bed board 123 along the length of the bed frame 11 to maintain the stability of the rehabilitation training equipment 20 during angle and position adjustment and storage.

[0034] The rotary drive mechanism 30 is specifically a worm gear mechanism, such as... Figure 4 As shown, the rotary drive mechanism 30 includes a drive motor 31, a worm gear 32 driven by the drive motor 31, and a worm wheel 33 cooperating with the worm gear 32. The drive motor 31 is mounted on the bed frame 11, and the worm wheel 33 is mounted on a rotating shaft 124 on the third bed plate 123. Specifically, the drive motor 31 is mounted vertically on the support frame 111, and the worm wheel 33 is connected to the output end of the drive motor 31 via a coupling.

[0035] In this embodiment, the self-locking characteristic of the worm gear mechanism can be used to keep the third bed board 123 and the rehabilitation training equipment 20 on it in the required angular position. In an optional embodiment, a hovering clutch mechanism can also be provided at the rotating shaft 124 to disengage when the third bed board 123 reaches the specified angular position, so that the rotating shaft 124 cannot rotate and is hovered at the specified angular position.

[0036] To enable patients to independently adjust the position of the rehabilitation training equipment, the bed frame 11 in this embodiment is provided with a control box 40, which is specifically installed on the bed board frame 112 for easy operation by the patient. The control box 40 is provided with a control board and at least one button 41. The control board is connected to the drive motor 31 for control, and the drive motor 31 is turned on or off by the button 41.

[0037] Soft pads can preferably be placed on the first bed board 121 and the second bed board 122 as needed to provide a more comfortable experience for the patient. When the patient is undergoing rehabilitation training, they first adjust the first bed board 121 to a suitable angle. After the patient has adjusted their lying position, the automatic control button 41 can adjust the position of the third bed board 123 and the rehabilitation training equipment, allowing the patient to begin rehabilitation training. Furthermore, during the rehabilitation training process, the patient can further adjust the position of the third bed board 123 and the rehabilitation training equipment according to their own situation, thus providing a better experience.

[0038] As an extended embodiment of this example, the bed frame 11 is preferably also provided with an indicator plate 50, such as... Figure 5As shown, the indicator panel 50 is located beside the third bed board 123. Specifically, the indicator panel 50 is a transparent panel with multiple scale lines 51 indicating the current angle of the third bed board 123. For example, a scale line is set every 10°, or every 5°. Furthermore, the scale line 51 corresponds to the current angle value, allowing nursing staff to directly observe and record the optimal (current) angle position suitable for the patient's rehabilitation training. This facilitates the patient's quick adjustment of the optimal angle position during the next rehabilitation training cycle.

[0039] In another extended embodiment of this example, the third bed board 123 can preferably move slightly along the length of the bed frame 11 under the drive of the translation drive mechanism, thereby allowing the patient to change the distance between themselves and the rehabilitation training equipment 20 without adjusting their body position, which is more beneficial for patients of different heights and improves the patient's experience. The translation drive mechanism is, for example, a lead screw drive mechanism, in which the third bed board and the rotation drive mechanism 30 are both mounted on the slider of the translation drive mechanism and can move as a whole under the control of the control box 40.

[0040] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
