[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 5, the present invention provides a technical solution: a nursing device for preventing muscle atrophy for bedridden patients, comprising a horizontal plate-shaped support base 1, on which a support frame 2 is movable and extended through a linear drive structure to bend and undulate;

[0030] Among them, the support frame 2 includes a thigh board 201 with one end rotatably connected to the edge of the base 1, and one end of the thigh board 201 is rotatably connected to the calf board 202. The bottom edge of the calf board 202 is vertically fixedly connected to the sole board 203, which supports the patient's lower limbs in turn. A binding structure for restraining the lower limbs is provided on the support frame 2. As the support frame 2 moves back and forth in the rise and fall, blood circulation is promoted to prevent muscle atrophy.

[0031] In this embodiment, the thigh plate 201, the calf plate 202 and the sole plate 203 are all straight strip plate structures, made of hard materials such as stainless steel. The plate structure is stable and durable, and has high stability in use.

[0032] To facilitate the patient's lower limbs to be stably placed on the support frame 2:

[0033] The middle parts of the thigh board 201 and the calf board 202 are respectively provided with grooves 13, which are arc-shaped structures and are used to support and place the thigh and calf parts of the patient, respectively. The sole of the patient's foot is against the sole board 203, and the patient's single leg is limitedly placed on the support frame 2;

[0034] The binding structure includes a bandage strip 14, and a plurality of bandage strips 14 are fixedly connected to one side of the thigh plate 201 and the calf plate 202. Velcro 16 is arranged on the surface of the bandage strip 14. A rectangular ring-shaped buckle 15 is correspondingly connected to the other side of the thigh plate 201 and the calf plate 202 relative to the bandage strip 14. One end of the bandage strip 14 passes through the buckle 15 and is folded around and attached to its own Velcro 16. When in use, the patient's lower limb is placed in the groove 13 of the support frame 2, and then the bandage strip 14 is used to bind the lower limb of the patient placed on the support frame 2, and the binding is tightened.

[0035] When in use, each leg uses a support frame 2, and the two legs are exercised separately.

[0036] When the patient's lower limbs move with the support frame 2, in order to avoid the patient's lower limbs being caught and injured during the extension process:

[0037] The thigh plate 201 and the calf plate 202 are alternately formed with spacing grooves 204, the groove length of which is 5 cm. The thigh plate 201 and the calf plate 202 are respectively fixedly connected to hinge plates 205 at the bottom of the alternate side edges, and the ends of the two hinge plates 205 are rotatably connected by pins.

[0038] That is, a safe gap is left between the thigh board 201 and the calf board 202. When the thigh board 201 and the calf board 202 rotate relative to each other, the larger spacing of the partition grooves 204 will not clamp the patient's leg skin when they are horizontally unfolded, thereby avoiding injuries.

[0039] It should be noted that the linear drive structure includes an electric slide 3 installed on the upper surface of the base 1, located directly below the support frame 2 and arranged horizontally along the frame body. A slider 4 is connected to the electric slide 3, and the bottom end of the calf plate 202 is fixedly connected to the slider 4.

[0040] After the lower limbs of the bedridden patient are restrained on the support frame 2, the electric slide 3 is started to work, driving the slider 4 to slide horizontally, driving the calf board 202 to move, and indirectly driving the thigh board 201 to rotate, so that the movement trajectory of the support frame 2 is a leg bending and stretching action, which also allows the patient's lower limbs to be constantly exercised and promote blood return from the lower limbs to the heart. Raising the feet can also relieve leg fatigue and varicose veins, change body position and deepen breathing, enhance cardiopulmonary endurance and efficiency, indirectly promote the function of the digestive system, and help intestinal peristalsis.

[0041] The linear drive equipment used above is existing technology, the brand is Dongyouda, the model is GCH8, and the type is linear module.

[0042] In order to facilitate the patient to raise the lower limbs to any height, flexibly adjust the posture, and use it adaptively according to the patient's needs to improve the use effect:

[0043] A vertical plate 5 is fixedly connected to the base 1, and one side of the vertical plate 5 is rotatably connected to one end edge of the electric slide 3 through a bearing. An L-shaped fixed plate 6 is fixedly connected to one end of the electric slide 3. A threaded sleeve 7 is fixedly embedded in the middle of the horizontal plate on the upper part of the fixed plate 6. The inner thread of the threaded sleeve 7 is connected to a threaded rod 8. The upper end of the threaded rod 8 is fixedly connected to a handle 9. An anti-sliding block 10 for rotation locking is fixedly connected to the bottom of the threaded rod 8. The anti-sliding block 10 is set to be a rubber part with a spherical structure.

[0044] When in use, the handle 9 is twisted to rotate the threaded rod 8, and the rotating threaded rod 8 is threadedly raised and lowered in cooperation with the threaded sleeve 7. In this embodiment, the handle 9 is rotated clockwise to move the threaded rod 8 downward; conversely, it is rotated counterclockwise to move upward, and the threaded rod 8 is operated to adjust the height.

[0045] When the electric slide 3 needs to be tilted and the height of the support frame 2 needs to be raised: lift it up directly from the threaded rod 8, and the other end of the electric slide 3 rotates with the bearing connected to the vertical plate 5 as the base point. Then, turn the handle 9 clockwise, and the threaded rod 8 moves downward, and adjust the required moving length according to the actual situation. Next, put down the electric slide 3, and the anti-sliding block 10 at the bottom of the threaded rod 8 contacts the surface of the base 1, and the electric slide 3 and the support frame 2 are in a tilted and raised state.

[0046] At the same time, the anti-sliding block 10 utilizes a high-friction rubber surface to contact the base 1 to prevent the threaded rod 8 from slipping and rotating, so that the support frame 2 maintains a certain height stability.

[0047] Furthermore, the outer surface of the anti-sliding block 10 is integrally provided with an arc-shaped protruding contact point 11 , and a rubber anti-slip sheet 12 is embedded on the upper surface of the base 1 . The upper surface is flush with the base 1 , and the bottom surface of the anti-sliding block 10 frictionally contacts the anti-slip sheet 12 .

[0048] That is, the anti-slip sheet 12 and the contact point 11 are added to strengthen the friction force, improve the anti-slip effect, prevent the threaded rod 8 from sliding and rotating under vibration force, and improve the stability and convenience of use.

[0049] In this embodiment, a rubber anti-skid plate 17 is attached to the bottom surface of the base 1. The anti-skid plate 17 is in high friction contact with the bed surface to prevent the base 1 from slipping and moving when the patient's lower limbs are exercised on the support frame 2, thereby improving the stability of use.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
