Description

Technical Field

[0001] This utility model relates to the field of rehabilitation exercise equipment; more specifically, it relates to an exercise device for bedridden patients. Background Technology

[0002] Bedridden patients, such as those who need to remain in bed long-term due to illness, accident, or other reasons, often face limitations in their mobility. Prolonged bed rest can easily lead to symptoms such as muscle atrophy, muscle weakness, joint stiffness, and decreased cardiopulmonary function. These symptoms not only affect the patient's daily life but may also trigger more serious health problems. Therefore, rehabilitation training for bedridden patients is particularly important.

[0003] Currently, most existing exercise devices for bedridden patients are fixed and integrated, making it inconvenient to exercise in bed and requiring patients to get out of bed. However, some patients are unable to get out of bed due to their condition. While some exercise devices can be used in bed, they often lack a fixed structure, making it difficult to quickly and easily install and fix them to the bed, resulting in poor stability. In addition, existing exercise devices have limited functions and cannot meet the diverse exercise needs of different patients, such as flexion and extension, adduction and introduction, and stepping. Therefore, there is an urgent need for an exercise device for bedridden patients to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an exercise device for bedridden patients to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an exercise device for bedridden patients, comprising:

[0006] The bed frame has a support frame mounted on its top surface. A rotating shaft is rotatably inserted into the middle of one side of the support frame, and a gear is fixedly sleeved on one side of the rotating shaft. A first rack is meshed at the top of the gear, and a first clamping plate is fixed at one end of the first rack. A second rack is meshed at the bottom of the gear, and a second clamping plate is fixed at one end of the second rack. A first spring is fixed to one side surface of the support frame. A pull bolt is slidably inserted into one side of the support frame near the rotating shaft. A slot is formed on the inner wall of one side of the support frame.

[0007] Two sets of protective cylinders are fixed to one side surface of the support frame, and two sets of second springs are fixed to one side surface of the support frame. The second springs are located inside the protective cylinders, and a foot plate is slidably inserted inside the protective cylinder. A third spring is fixed to one side of the foot plate, and a baffle is fixed to one end of the second spring. A sliding groove is opened on one side surface of the support frame, and a slider is fixed to one side of the sliding groove. A slider is slidably inserted inside the sliding groove, and a spherical shaft is fixed to the top of the slider.

[0008] Preferably, one end of the pull bolt is configured as a large cuboid, and one side of the large cuboid is fixedly connected to one end of the first spring. The other end of the pull bolt is configured as a small cuboid, and the first spring is slidably sleeved on the outer surface of the small cuboid. The size of the small cuboid is adapted to the size of the gap between the two sets of teeth on the gear. The small cuboid slides on the gap between the two sets of teeth, so that the small cuboid of the pull bolt is inserted into the gap between the gear teeth when no external force is applied.

[0009] Preferably, the size of the slot is adapted to the size of the small cuboid of the pull bolt, and the small cuboid slides inside the slot, which facilitates the fixing of the pull bolt.

[0010] Preferably, the foot plate is wrapped with an anti-slip silicone pad, the second clamp is wrapped with an anti-slip pad on the inside, and the first clamp is wrapped with an anti-slip pad on the inside, which makes the support frame more stable and makes the patient more comfortable and safer to use.

[0011] Preferably, the size of the baffle is larger than the diameter of the second spring and smaller than the inner diameter of the protective cylinder, so that the patient can push the footboard into the protective cylinder more smoothly and comfortably.

[0012] Preferably, the slider is provided in two sets, and the two sets of sliders are symmetrically distributed on both sides of the slide groove. The surface of the slider is provided with grooves that are adapted to the sliders. The sliders slide inside the grooves, making the movement of the slider inside the slide groove more stable and smooth.

[0013] The technical effects and advantages of this utility model are as follows: This utility model uses the cooperation between the support frame, rotating shaft, gear, first rack, first clamping plate, second rack, second clamping plate, pull bolt, first spring and slot to facilitate quick installation of the device on the bed for patients to exercise. The device has a fixed structure that can be freely adjusted in position, which brings convenience to patients and makes them more comfortable to use. It also improves the safety and flexibility of the device.

[0014] By using the protective cylinder, second spring, foot plate, third spring, baffle, slider, slide groove, slider and spherical shaft in combination, it is easy to provide patients with a variety of exercise modes to meet the rehabilitation needs of different patients, making the patients' exercise more comprehensive and thus improving the rehabilitation effect and enhancing the practicality of the device.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, this embodiment proposes an exercise device for bedridden patients, including a bed body 1. A support frame 2 is installed on the top surface of the bed body 1. A rotating shaft 3 is rotatably inserted into the middle of one side of the support frame 2, and a gear 4 is fixedly sleeved on one side of the rotating shaft 3. A first rack 5 is meshed at the top of the gear 4, and a first clamping plate 6 is fixed at one end of the first rack 5. A second rack 7 is meshed at the bottom of the gear 4, and a second clamping plate 8 is fixed at one end of the second rack 7. A first spring 10 is fixed to one side surface of the support frame 2. A pull bolt 9 is slidably inserted into one side of the support frame 2 near the rotating shaft 3. A groove 1 is formed on the inner wall of one side of the support frame 2. 1. One end of the pull bolt 9 is set as a large cuboid, and one side of the large cuboid is fixedly connected to one end of the first spring 10. The other end of the pull bolt 9 is set as a small cuboid. The first spring 10 is slidably sleeved on the outer surface of the small cuboid. The size of the small cuboid is adapted to the size of the gap between the two sets of gear teeth on the gear 4. The small cuboid slides on the gap between the two sets of gear teeth. The size of the slot 11 is adapted to the size of the small cuboid of the pull bolt 9. The small cuboid slides inside the slot 11. The inside of the foot plate 14 is wrapped with an anti-slip silicone pad. The inside of the second clamping plate 8 is wrapped with an anti-slip pad. The inside of the first clamping plate 6 is wrapped with an anti-slip pad.

[0023] In this embodiment, when the device needs to be installed on the bed for exercise, firstly, the support frame 2 is placed in a suitable position on the bed 1, and then the pull bolt 9 is pulled outward until the small cuboid of the pull bolt 9 slides completely out of the gap between the slot 11 and the gear 4 teeth. At the same time, the first spring 10 is stretched in the same direction. Then, the rotating shaft 3 is rotated counterclockwise to drive the gear 4 to rotate counterclockwise. The gear 4 drives the first rack 5 to move to the left and the second rack 7 to move to the right, causing the first clamping plate 6 and the second clamping plate 8 to continuously clamp the bed 1 inward until the rotating shaft 3 can no longer rotate. Finally, the pull bolt 9 is released, and the small cuboid of the pull bolt 9 will slide back into the gap between the gear 4 teeth and the slot 11 under the elastic force of the first spring 10. At this time, the entire device is fixed.

[0024] Example 2

[0025] like Figure 1 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: two sets of protective cylinders 12 are fixed on one side surface of the support frame 2, two sets of second springs 13 are fixed on one side surface of the support frame 2, the second springs 13 are located inside the protective cylinders 12, and a foot plate 14 is slidably inserted inside the protective cylinders 12, and a third spring 15 is fixed on one side of the foot plate 14. A baffle 16 is fixed at one end of the second spring 13. A sliding groove 18 is opened on one side surface of the support frame 2, and a slider 17 is fixed on one side of the sliding groove 18. A slider 19 is slidably inserted inside the sliding groove 18. A spherical shaft 20 is fixed at the top of the slider 19. The size of the baffle 16 is larger than the diameter of the second spring 13 and smaller than the inner diameter of the protective cylinder 12. Two sets of sliders 17 are provided, and the two sets of sliders 17 are symmetrically distributed on both sides of the sliding groove 18. Grooves that match the sliders 17 are opened around the surface of the sliders 19, and the sliders 17 slide inside the grooves.

[0026] In this embodiment, the patient's foot is first placed inside the foot plate 14 and fixed in place. When there is a need for leg flexion and extension or stepping exercises, the foot can be pressed down on the foot plate 14 to drive the slider 19 to move vertically along the surface of the slider 17 inside the slide groove 18. The foot plate 14 then pushes the baffle 16 to move into the protective cylinder 12, while driving the second spring 13 to compress in the same direction. Then the foot stops pressing down on the foot plate 14 and pulls the foot plate 14 outward to bend the leg. The bottom of the foot plate 14 has a spherical shaft 20 as support to help the leg bend. The two sets of foot plates 14 can be pressed down in the same direction at the same time to perform flexion and extension exercises, or they can be pressed down separately in a cycle to perform stepping exercises. When there is a need for leg adduction and inward adduction exercises, the feet can be pushed outward to make the foot plate 14 drive the slider 19 to move laterally along the surface of the slider 17 inside the slide groove 18, while driving the third spring 15 to stretch in the same direction. The third spring 15 has elastic resistance to assist the patient in exercising. This operation can be repeated.

[0027] Working principle: When using the equipment, first place the support frame 2 in a suitable position on the bed, then pull out the bolt 9 and rotate the shaft 3 until the first clamping plate 6 and the second clamping plate 8 are completely pressed against the bed. Then release the bolt 9. When starting to exercise, first place your feet inside the foot plate 14 and tie them in place. Then, according to your exercise needs, choose to step on the foot plate 14 vertically or pull the foot plate 14 horizontally for cyclical exercise. The above is the complete working principle of this practical device.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
