Description

Technical Field

[0001] The invention relates to the technical field of mechanical walking assistance devices for neurosurgery nursing, and in particular to a walking assistance device for neurosurgery nursing. Background Art

[0002] With the continuous advancement of medical technology, the success rate of neurosurgery has significantly improved, but the postoperative rehabilitation process is still full of challenges. Patients usually face difficulty in movement in the early stage after surgery and need to use special walking assistance devices for rehabilitation training. Existing walking assistance devices mainly include crutches, walkers and other forms. These devices can help patients support their weight and maintain balance to a certain extent, thereby achieving the purpose of walking exercise.

[0003] After searching, Chinese patent CN113559458A discloses a neurosurgery assisted walking nursing device. The present invention discloses a neurosurgery assisted walking nursing device, including a U-shaped base, the bottom of the U-shaped base and positions near the four ends are provided with universal wheels, the top of the U-shaped base and positions near the middle of both sides are provided with device fixing mechanisms, the top of the U-shaped base is provided with symmetrically distributed support mechanisms, the top of the U-shaped base and positions near the rear ends are provided with symmetrically distributed first fixed vertical plates, and an in-situ walking mechanism is movably connected between the two first fixed vertical plates and positions near the bottom. In the neurosurgery assisted walking nursing device, patients can perform rehabilitation training through the in-situ walking mechanism, and the speed of the drive motor is controlled by the control mechanism, thereby adjusting the moving speed of the conveyor belt, playing an auxiliary role, which is beneficial to the patient's walking rehabilitation. This training method does not require a large space environment, which is beneficial for patients to perform rehabilitation training in a small space.

[0004] However, the above-mentioned walking assistance devices have some shortcomings. On the one hand, the device is bulky in structure design, which makes it inconvenient for patients to operate and move flexibly, especially when used in a small ward or home environment. On the other hand, some assistive devices lack effective adjustment functions and are difficult to adapt to the needs of patients of different heights and body shapes, resulting in a significant reduction in comfort. In addition, some assistive devices take up a lot of space when not in use by patients, which is not conducive to storage and storage, causing inconvenience to ward management and family life. In response to the above problems, existing technical solutions are also constantly being improved and innovated.

[0005] Therefore, the present invention proposes a walking assist device for neurosurgery nursing to solve the above problems. Summary of the invention

[0006] Technical problems to be solved: Traditional walking assistance devices for nursing have many deficiencies when patients are doing rehabilitation exercises. First of all, these devices may not provide sufficient leg support, making it easy for patients to fall during walking, thus causing secondary injuries, prolonging the rehabilitation time and increasing medical costs. Secondly, traditional walking assistance devices for nursing often require the patient's own leg strength, which undoubtedly increases the physical burden on the patient. For patients in the rehabilitation stage, excessive leg strength may affect their recovery process and even cause muscle strains or other accidents. Therefore, improving the walking assistance device and enhancing its safety and comfort are crucial for the patient's rehabilitation.

[0007] In view of the deficiencies of the prior art, the present invention provides a walking assistance device for neurosurgical nursing, thereby solving the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0009] A walking assistance device for neurosurgical nursing, comprising a U-shaped plate, on which an arm fixing device, a handle and a braking device are installed. An expansion rod is installed on the lower side of the U-shaped plate, and the expansion rod is movably connected to an expansion rod fixing seat, and the expansion rod fixing seat is fixedly connected to a U-shaped base. It is characterized in that: a leg fixing mechanism, a device stabilizing mechanism, a front steering wheel mechanism and a rear wheel movement mechanism are installed on the U-shaped base, and a braking mechanism is installed on the front wheel;

[0010] Starting from the U-shaped plate, a walking assistance device for neurosurgical nursing is sequentially connected with an arm supporting mechanism, a height adjustment mechanism, a leg fixing mechanism, a device stabilizing mechanism, a front steering wheel mechanism, a rear wheel movement mechanism and a braking mechanism from top to bottom.

[0011] In a possible implementation manner, the arm supporting mechanism includes a U-shaped plate, a fixing belt is fixedly installed above the U-shaped plate, the fixing belt is movably connected to a buckle, the buckle is fixedly connected to the U-shaped plate, a handle is fixedly installed at the front end of the U-shaped plate, and a braking handle is fixedly installed on the handle.

[0012] In a possible implementation manner, the height adjustment mechanism includes an expansion rod fixing seat, the expansion rod fixing seat is movably connected to an expansion rod, and the expansion rod is fixedly connected to the U-shaped plate.

[0013] In a possible implementation manner, the leg fixing mechanism includes a fixator mounting seat, the fixator mounting seat is movably connected to a height adjustment seat, the height adjustment seat is movably connected to a knee fixator, a thigh fixator is installed above the knee fixator, a calf fixator is installed below the knee fixator, and the fixator mounting seat is movably connected to the inner groove of the U-shaped base.

[0014] In a possible implementation, a rotating device is provided between the height adjustment seat and the knee fixator in the leg fixing mechanism. The thigh fixator and the calf fixator are connected to the knee fixator through a milk tape, and fixing devices are provided on all three components.

[0015] In a possible implementation, the device stabilizing mechanism includes a stabilizing wheel support frame, which is movably connected to the stabilizing wheel, and the stabilizing wheel support frame is fixedly connected to the U-shaped base.

[0016] In a possible implementation, the front steering wheel mechanism includes a front wheel fixing seat, which is movably connected to the rotating table. The rotating table is movably connected to the front wheel through a front wheel shaft, and the front wheel fixing seat is fixedly connected to the U-shaped base.

[0017] In a possible implementation, the rear wheel movement mechanism includes a rear wheel mounting seat, which is movably connected to the rear wheel through a shaft, and the rear wheel mounting seat is fixedly connected to the U-shaped base.

[0018] In a possible implementation, the braking mechanism includes a brake connector seat, which is connected to the brake caliper by a bolt. The brake caliper is fixedly connected to the brake wire and can be reinforced by a fastening screw. The brake wire is movably connected to the brake connector seat, and the brake connector seat is fixedly connected to the brake pad.

[0019] In a possible implementation, the brake wire is connected to the brake handle, and the brake connector seat is fixedly connected to the U-shaped base.

[0020] Advantages compared with the prior art:

[0021] 1. In this solution, when the patient is unable to control the device, through the action of the brake handle, the patient only needs to squeeze the brake handle. After the brake handle is pulled, the brake wire will lift the brake caliper, the connecting seat will contract inward, and the brake pad will clamp the front wheel at this time, and the front wheel will stop moving. After the patient releases the hand, the front wheel will return to the moving state, keeping the device in a controllable state.

The telescopic rod is also movably connected to the telescopic rod fixing seat, and can adjust the height of the U-shaped frame according to the patient's height to adapt to the patient's height and meet the needs of different patients, so as to better carry out the work of restoring the patient's motor ability.

[0023] 3. In this solution, the leg fixing mechanism and the arm supporting mechanism of the device are designed with a detachable function. Patients can decide whether to use the arm supporting mechanism and the leg fixing mechanism according to their own physical recovery situation. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more solutions or examples.

[0038] The technical solutions in the embodiments of this application are to solve the problems in the above background technology, and the general idea is as follows:

[0039] Please refer to Figure 1 - Figure 7 As shown, this embodiment introduces the specific structure of a walking assistance device for neurosurgical care, including a U-shaped plate 1, on which an arm fixing device, a handle 19 and a braking device are installed. A telescopic rod 2 is installed under the U-shaped plate 1. The telescopic rod 2 is movably connected to a telescopic rod fixing seat 3, and the telescopic rod fixing seat 3 is fixedly connected to a U-shaped base 4. A leg fixing mechanism, a device stability mechanism, a steering front wheel mechanism and a rear wheel movement mechanism are installed on the U-shaped base 4. In addition, a braking mechanism is installed on the front wheel 10 to ensure the safety and stability of the device.

[0040] Starting from the U-shaped plate 1, a walking assistance device for neurosurgical care is sequentially connected with an arm support mechanism, a height adjustment mechanism, a leg fixing mechanism, a device stability mechanism, a steering front wheel mechanism, a rear wheel movement mechanism and a braking mechanism from top to bottom.

[0041] The arm support mechanism includes a U-shaped plate 1. A fixing belt 22 is fixedly installed above the U-shaped plate 1. The fixing belt 22 is movably connected to a buckle 21, and the buckle 21 is fixedly connected to the U-shaped plate 1. When the patient is in the initial stage of recovering movement and has weak leg support force, the patient can fix the arm on the U-shaped plate 1 through the fixing belt 22 and the buckle 21 to provide the main support force for the upper body of the patient. A handle 19 is fixedly installed at the front end of the U-shaped plate 1, and a brake handle 20 is fixedly installed on the handle 19. During the movement of the patient, the patient can hold the handle to provide support for the hand, which not only ensures the stability of the patient during the recovery movement, but also can effectively control the device through the brake handle when needed by the patient to ensure the safety and convenience of the movement.

[0042] The height adjustment mechanism includes a telescopic rod fixing seat 3. The telescopic rod fixing seat 3 is movably connected to the telescopic rod 2, and the telescopic rod 2 is fixedly connected to the U-shaped plate 1. The height adjustment mechanism can adjust the height of the U-shaped plate 1 according to the patient's height, improving the versatility and comfort of the device to meet the needs of more patients with different heights.

[0043] The leg fixing mechanism includes a fixator mounting seat 14. The fixator mounting seat 14 is movably connected to the height adjustment seat 15, the height adjustment seat 15 is movably connected to the knee fixator 17. Above the knee fixator 17, a thigh fixator 16 is installed, and below the knee fixator 17, a calf fixator 18 is installed. The fixator mounting seat 14 is movably connected to the inner groove of the U-shaped base 4 for left and right movement, facilitating the patient's forward and backward movement. Among them, the height adjustment seat 15 can move up and down, specifically adjusted according to the patient's height. A rotating device is provided between the height adjustment seat 15 and the knee fixator 17 to facilitate the patient's leg bending movement. The thigh fixator 16 and the calf fixator 18 are connected to the knee fixator 17 through milk tape. The milk tape has good elasticity and stretchability, can closely fit the body, prevent varicose veins, and relieve muscle fatigue. And these three components are all provided with fixing devices, the material is soft and has a certain supporting force. When the patient uses the leg fixing mechanism, first open the fixing devices of the calf fixator, thigh fixator, and knee fixator, and then the patient must, with the help of medical staff, carefully place the affected leg into the device and then fix the fixing device while ensuring the patient's comfort, and move slowly.

[0044] The device stability mechanism includes a stabilizer wheel support frame 5. Among them, the stabilizer wheel support frame 5 is movably connected to the stabilizer wheel 6, and the stabilizer wheel support frame 5 is fixedly connected to the U-shaped base 4 by bolts, ensuring that the patient can maintain stability when using the device, preventing tipping over and maintaining balance.

[0045] The front steering wheel mechanism includes a front wheel fixing seat 7. The front wheel fixing seat 7 is movably connected to the rotating platform 8, and the rotating platform 8 is movably connected to the front wheel 10 through the front wheel shaft 9. The front wheel fixing seat 7 is fixedly connected to the U-shaped base 4 by bolts. The front steering wheel mechanism realizes the steering function through the rotating platform 8, making it more convenient for the patient to use.

[0046] The rear wheel movement mechanism includes a rear wheel mounting seat 23. The rear wheel mounting seat 23 is movably connected to the rear wheel 24 through an axle, and the rear wheel mounting seat 23 is fixedly connected to the U-shaped base 4.

[0047] The braking mechanism includes a brake connector seat 25. The brake connector seat 25 is bolted to the brake caliper 12. The brake caliper 12 is fixedly connected to the brake cable 13 and can be further strengthened by fastening screws. The brake cable 13 is movably connected to the brake connector seat 25. The brake connector seat 25 is fixedly connected to the brake pad 11. The brake cable 13 is connected to the brake handle 20. The brake connector seat 25 is fixedly connected to the U-shaped base 4. When the patient is unable to control the device, the brake handle 20 can be pinched. After the brake handle 20 is pulled, the rear brake cable 13 lifts the brake caliper 12 upwards, causing the connecting seat to contract inwards, and the brake pad 11 clamps the front wheel 10, stopping the front wheel 10. After the patient releases the hand, the front wheel 10 can continue to move.

[0048] Please refer to Figure 1 As shown, the device first automatically adjusts the height of the telescopic rod 2 according to the patient's height, and the height adjustment seat 15 is also adjusted to the corresponding height for the convenience of the patient. Subsequently, after opening the thigh fixator 16, the knee fixator 17, and the calf fixator 18 to fix the patient's legs, the hands are fixed on the U-shaped plate 1 through the fixing straps 22 and the buckles 21. Then the patient can start to move slowly;

[0049] Specifically, the patient can horizontally move the legs through the movable connection between the leg fixing mechanism and the U-shaped base 4, and then perform the leg bending action through the rotating device between the height adjustment seat 15 and the knee fixator 17. During the movement, if the patient feels unable to stand and recover due to physical exhaustion, the movement of the front wheel 10 can be quickly stopped by the brake handle 20. If the patient has a tendency to fall during the walking recovery process and falls sideways, the device's stability mechanism can prevent the patient from falling sideways, ensuring that the patient can maintain stable movement when using the device for recovery exercise. At the same time, the leg fixing mechanism and the buckles 21 and fixing straps 22 for hand fixing can provide a certain amount of support force for the patient, ensuring that the patient can have sufficient support force during the initial recovery exercise. In addition, the leg fixing mechanism and the height adjustment mechanism can be adjusted to the corresponding positions according to the patient's height to meet the needs of different patients;

[0050] In summary, it should be noted that if the patient's mobility is too weak or the patient has no mobility for the time being, it is recommended to use all the mechanisms in the device that provide support for the patient to avoid possible accidents caused by inconvenient movement. If the patient recovers a certain amount of motor ability, the buckle 21 and the fixing belt 22 for hand fixation can be removed. At this time, the patient can try to perform some simple self-movements, which will help to accelerate the rehabilitation process. If the patient recovers most of their mobility, on the premise of ensuring safety, the leg fixation mechanism can also be removed and the patient can try to move using the device by themselves. At this time, the patient can use the device for exercise more freely, which can not only further enhance the patient's physical strength and muscle strength, but also promote blood circulation throughout the body. At the same time, it should be noted that during the whole process, corresponding adjustments should be made according to the specific situation of the patient and the doctor's advice to ensure that the changes at each stage meet the actual needs and physical conditions of the patient.

[0051] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or variations derived therefrom are still within the protection scope of the present invention.
