Description
Technical Field
[0001] This utility model relates to the field of medical and nursing technology, and in particular to a walking assistance device for neurosurgical nursing. Background Technology
[0002] Neurosurgical patients mainly suffer from traumatic brain injury and various hemorrhagic diseases. After treatment for these diseases, patients often have difficulty walking, mainly manifested as limb incoordination. Therefore, they often need walking aids to assist walking and rehabilitation.
[0003] Existing walking aids for neurosurgical care typically include wheels to facilitate movement, which undoubtedly improves mobility. However, in these devices, the wheels are located at the bottom, making steering unrestricted and difficult to control. This results in unpredictable walking direction, making it challenging for patients to control the direction of movement. Maintaining a fixed direction with the entire device is relatively difficult, and turning often requires rotating the entire device, which adds to the strain for patients with limb incoordination or difficulty walking. Utility Model Content
[0004] To address the above shortcomings, this invention provides a walking aid for neurosurgical nursing, which solves the problems of difficulty in directional walking control and turning operation of existing walking aids for neurosurgical nursing with wheels.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A walking aid for neurosurgical care includes a support frame and walking wheels disposed at the bottom of the support frame, the walking wheels including front walking wheels and rear walking wheels;
[0007] The support frame has a vertically mounted sleeve on each of its front two sides, and the front traveling wheel is rotatably mounted on the bottom of the sleeve.
[0008] A rotating rod is fitted inside the sleeve. One end of the rotating rod is connected to the front traveling wheel, and the other end extends upward out of the sleeve. A handle is provided at the end of the rotating rod that extends out of the sleeve, so that the rotating rod can be rotated by the handle to make the front traveling wheel swing left and right to change the traveling direction of the front traveling wheel.
[0009] Furthermore, a transversely positioned portion is provided between the rotating rod and the handle, with the rear end of the transverse portion connected to the rotating rod and the front end connected to the handle;
[0010] The grip is set vertically and its bottom is connected to the horizontal part so that the rotating rod can be rotated by swinging.
[0011] Furthermore, the front end of the transverse portion faces the same direction as the travel direction of the front traveling wheel.
[0012] Furthermore, the horizontal part includes a horizontal sleeve, a horizontal rod, and a horizontal rod limiting block. The horizontal rod is sleeved inside the horizontal sleeve and can slide back and forth along the horizontal sleeve. The horizontal rod limiting block is fixedly installed at the rear end of the horizontal rod and is larger than the opening of the horizontal sleeve.
[0013] The handle is installed at the front end of the horizontal bar, and a locking block is provided on the handle;
[0014] A locking hole is provided at the top of the support frame so that when the handle slides backward with the horizontal bar in the horizontal sleeve to a certain position, the locking block is located in the locking hole, and the handle cannot swing at this time; and when the handle slides forward with the horizontal bar in the horizontal sleeve to a certain position, the locking block separates from the locking hole, and the handle can swing at this time.
[0015] Furthermore, the front end of the horizontal bar is provided with an upwardly pointing vertical sleeve;
[0016] The bottom of the grip is provided with a vertical rod, and a vertical rod limiting block is fixedly installed at the bottom end of the vertical rod. The vertical rod is sleeved in the vertical sleeve and can slide up and down along the vertical sleeve. The vertical rod limiting block is larger than the opening of the vertical sleeve.
[0017] The locking hole is positioned with its opening facing upwards. When the handle moves the vertical rod upwards to a certain position, it can cause the locking block to disengage from the locking hole. Conversely, when the handle moves the vertical rod downwards to a certain position, it can cause the locking block to enter the locking hole.
[0018] Furthermore, the support frame is provided with hand placement portions on both sides of the top, the hand placement portions extend forward and their front ends are located above the horizontal portion, and the locking holes are opened on the top surface of the front end of the hand placement portions.
[0019] Furthermore, a slot is provided at the front end face of the hand placement part, and when the handle drives the vertical rod to slide down to a certain position and the locking block enters the locking hole, the vertical rod is located in the slot.
[0020] Furthermore, a flexible cushioning element is provided on the top surface of the hand placement part.
[0021] Furthermore, a flexible sleeve is provided on the grip.
[0022] Furthermore, the front and rear wheels are self-locking wheels.
[0023] Compared with the prior art, the beneficial effects of this utility model are: this utility model can drive the rotating rod to rotate through the handle, causing the front walking wheel to sway. At this time, the walking direction of the front walking wheel changes, so as to realize the front walking wheel to change in multiple walking directions, making steering relatively easy and solving the problem of difficult steering operation; at the same time, by holding the handle, the rotating rod can be kept from rotating, thereby ensuring that the walking direction of the front walking wheel remains unchanged, thus solving the problem of difficult control of directional walking.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0041] Please refer to Figures 1 to 8 A preferred embodiment of this utility model provides a walking assistance device for neurosurgical nursing. The walking assistance device mainly includes a support frame 10 and walking wheels set at the bottom of the support frame 10. The walking wheels set at the bottom of the support frame 10 facilitate the movement of the support frame 10. When in use, the patient holds the support frame 10 to assist walking, and then the walking wheels at the bottom of the support frame 10 facilitate the movement of the entire walking assistance device.
[0042] Please continue to refer to Figures 1 to 8 The walking wheels include front walking wheels 31 and rear walking wheels 32. In this exemplary embodiment, there are two front walking wheels 31 and two rear walking wheels 32. The two front walking wheels 31 are located on both sides of the front end of the bottom of the support frame, and the two rear walking wheels 32 are located on both sides of the rear end of the bottom of the support frame. At this time, the four walking wheels can ensure the smooth movement of the support frame 10.
[0043] The support frame 10 has a vertically mounted sleeve 11 on each of its front ends. A front traveling wheel 31 is rotatably mounted on the bottom of the sleeve 11, giving it a steering function to facilitate the turning of the support frame 10. In a preferred embodiment, the front traveling wheel 31 is mounted at the bottom opening of the sleeve 11 via ball bearings, allowing for a certain range of rotation, such as a 360° turn. In this exemplary embodiment, the rear traveling wheel 32 does not have a steering function; it only has a forward / backward walking direction. In this case, the turning of the support frame 10 is mainly achieved through the steering of the front traveling wheel 31. It is understood that in other preferred embodiments, the rear traveling wheel 32 can also turn.
[0044] Preferably, the front traveling wheel 31 and the rear traveling wheel 32 are self-locking traveling wheels. In this case, when it is desired to prevent the front traveling wheel 31 and the rear traveling wheel 32 from rotating, such as when it is necessary to fix the traveling auxiliary device in a certain position, the self-locking device of the front traveling wheel 31 and the rear traveling wheel 32 limits the rotation of the front traveling wheel 31 and the rear traveling wheel 32. At this time, the front traveling wheel 31 and the rear traveling wheel 32 can no longer rotate. The self-locking front traveling wheel 31 and the rear traveling wheel 32 facilitate fixing the support frame 10 in a certain position. When it is necessary to move, the self-locking of the front traveling wheel 31 and the rear traveling wheel 32 can be released to move the support frame 10.
[0045] A rotating rod 12 is fitted inside the vertically positioned sleeve 11, allowing the rotating rod 12 to rotate within the sleeve 11. The rotating rod 12 can be rotatably mounted within the sleeve 11 via a ball bearing.
[0046] One end of the rotating rod 12 is connected to the front traveling wheel 31, so that when it rotates, it can drive the front traveling wheel 31 to turn, that is, change the traveling direction of the front traveling wheel 31. The other end of the rotating rod 12 extends upward out of the sleeve 11, and a handle 20 is provided at the end of the rotating rod 12 that extends out of the sleeve 11, so that the rotating rod 12 can be rotated by the handle 20 to make the front traveling wheel 31 swing left and right to change the traveling direction of the front traveling wheel 31.
[0047] In practice, when using the walking assistance device of this utility model, the user holds the handles 20 with both hands. When it is necessary to adjust or change the walking direction of the front walking wheel 31, such as changing the walking direction of the corresponding front walking wheel 31 from forward to left, the handles 20 drive the rotating rod 12 to rotate, causing the front walking wheel 31 to sway to the left. At this time, the walking direction of the front walking wheel 31 changes from forward to left. Or, when it is necessary to change the walking direction of the corresponding front walking wheel 31 from right to forward, the handles 20 drive the rotating rod 12 to rotate, causing the front walking wheel 31 to sway forward. At this time, the walking direction of the front walking wheel 31 changes from right to forward. In a similar way, the front walking wheel 31 can change to multiple walking directions such as left, forward, and right, making steering relatively easy and solving the problem of difficult steering operation. Moreover, by holding the handles 20, the rotating rod 12 can be kept stationary, thereby ensuring that the walking direction of the front walking wheel 31 remains unchanged, such as keeping it forward, thus solving the problem of difficult control of directional walking.
[0048] Preferably, the handle 20 is fitted with a flexible sleeve 26, which makes it more comfortable for the patient to hold the handle 20.
[0049] A transversely positioned portion 40 is provided between the rotating rod 12 and the handle 20. The rear end of the transverse portion 40 is connected to the rotating rod 12, and the front end is connected to the handle 20. The handle 20 is vertically positioned to facilitate the patient's grip. The bottom of the handle 20 is connected to the transverse portion 40. At this point, the handle 20 and the rotating rod 12 do not overlap in the vertical projection. The handle 20 has a lever arm when rotating, making it easier to rotate the rotating rod 12 by swinging the handle 20. By providing the transverse portion 40, it is easier for the handle 20 to drive the rotating rod 12 to rotate, making it easier for the patient to control the handle 20 and the rotating rod 12, and also easier for the patient to control the front walking wheel 31.
[0050] Preferably, the front end of the transverse part 40 is aligned with the walking direction of the front walking wheel 31. This arrangement enables the front walking wheel 31 to remain forward when the handle 20 is pushed forward. Thus, the patient only needs to push the handle 20 forward to keep the front walking wheel 31 forward, which means that the walking aid device can move forward.
[0051] The horizontal part 40 includes a horizontal sleeve 41, a horizontal rod 42, and a horizontal rod limiting block 43. The horizontal rod 42 is sleeved inside the horizontal sleeve 41 and can slide back and forth along the horizontal sleeve 41. The horizontal rod limiting block 43 is fixedly installed at the rear end of the horizontal rod 42 and is larger than the opening of the horizontal sleeve 41, thereby restricting the horizontal rod 42 from moving forward to a certain position and preventing it from moving further. In this exemplary embodiment, the horizontal rod 42 is a square rod, and the inner hole of the horizontal sleeve 41 matches the horizontal rod 42, so that the horizontal rod 42 can only move back and forth within the horizontal sleeve 41 and cannot rotate.
[0052] The handle 20 is installed at the front end of the horizontal bar 42, and a locking block 21 is provided on the handle 20. The locking block 21 is a square block.
[0053] A locking hole 13 is provided at the top of the support frame 10. When the handle 20 slides backward with the horizontal rod 42 within the horizontal sleeve 41 to a certain position, the locking block 21 is located within the locking hole 13. The locking block 21 matches the locking hole 13, so the handle 20 cannot swing. The handle 20, which cannot swing, cannot drive the rotating rod 12 to rotate, thus keeping the forward walking wheel 31's walking direction unchanged. In a preferred embodiment, when the handle 20 is kept stationary by the matching relationship between the locking block 21 and the locking hole 13, the handle 20 moves forward, and the forward walking wheel 31's walking direction is also forward. This ensures that the forward walking wheel 31 continues to move forward, meaning the walking assistance device moves forward.
[0054] When the handle 20 slides forward with the horizontal bar 42 in the horizontal sleeve 41 to a certain position, the locking block 21 separates from the locking hole 13. At this time, the handle 20 can swing, and the swinging handle 20 can drive the rotating rod 12 to rotate, which facilitates the change of the walking direction of the front walking wheel 31, and also facilitates the patient's control of the front walking wheel 31.
[0055] By restricting the grip 20 from swinging, the direction of travel of the front walking wheel 31 can be kept constant, thus solving the problem of difficult control of directional walking; and after the restriction on the grip 20 is lifted, the grip 20 can swing and drive the rotating rod 12 to rotate, thus enabling the control of the direction of travel of the front walking wheel 31 and solving the problem of difficult steering operation.
[0056] The horizontal rod 42 has a vertically extending sleeve 44 at its front end, and a vertical rod 22 is located at the bottom of the handle 20. A vertical rod limiting block 23 is fixedly installed at the bottom of the vertical rod 22. The vertical rod 22 is fitted inside the vertical sleeve 44 and can slide up and down along the sleeve. The vertical rod limiting block 23 is larger than the opening of the vertical sleeve 44, thus restricting the vertical rod 22 from moving upward to a certain position and preventing further movement. It is understood that the handle 20 is also larger than the opening of the vertical sleeve 44. The vertical rod 22 is a square rod, and the inner hole of the vertical sleeve 44 matches the vertical rod 22, so the vertical rod 22 can only move up and down within the vertical sleeve 44 and cannot rotate.
[0057] The locking hole 13 is set with the opening facing upward. When the handle 20 drives the vertical rod 22 to slide upward to a certain position, it can drive the locking block 21 to move upward away from the locking hole 13. When the handle 20 drives the vertical rod 22 to slide downward to a certain position, it can drive the locking block 21 into the locking hole 13.
[0058] During implementation, when the handle 20 moves upward, refer to... Figures 1 to 3 This allows the locking block 21 to move upwards and disengage from the locking hole 13. At this point, the handle 20 is unrestricted and can move forward a certain position or swing to rotate the rotating rod 12. When the handle 20 moves backwards with the horizontal rod 42 to a certain position, aligning the locking block 21 with the locking hole 13, the handle 20 causes the vertical rod 22 to slide downwards, allowing the locking block 21 to enter the locking hole 13. (Refer to...) Figure 4 and Figure 5 At this time, due to the mutual limiting effect of the locking block 21 and the locking hole 13, the handle 20 cannot move on the horizontal plane, that is, it cannot swing forward, backward or left and right. At this time, the direction of travel of the rotating rod 12 and the front traveling wheel 31 at its bottom can be changed and kept unchanged, thus maintaining the forward direction.
[0059] Preferably, the support frame 10 has hand placement parts 14 on both sides of the top. The hand placement parts 14 extend forward and their front ends are located above the horizontal part 40. The handle 20 is higher than the hand placement parts 14. By setting the hand placement parts 14, it is convenient for the patient to place their hands on the hand placement parts 14 when using the device, which facilitates the support of the walking aid for the patient. When the patient places their hands on the hand placement parts 14, it does not hinder the patient from holding the handle 20 or controlling the handle 20.
[0060] The locking hole 13 is located on the top surface of the front end of the hand placement part 14. The locking hole 13 is a square block, and the locking block 21 matches the locking block 21.
[0061] Preferably, a slot 16 is provided at the front end face of the hand rest 14. When the handle 20 drives the vertical rod 22 to slide down to a certain position and the locking block 21 enters the locking hole 13, the vertical rod 22 is located in the slot 16. By setting the slot 16, the left and right limits of the vertical rod 22 can be realized, thereby assisting in the limitation of the handle 20 and ensuring that the handle 20 cannot swing when the locking block 21 enters the locking hole 13.
[0062] The hand placement part 14 has a flexible cushioning element 15 on its top surface, which makes it more comfortable for the patient to place their hand on the top surface of the hand placement part 14. The cushioning element 15 is generally concave arc-shaped, and its extension direction is consistent with the extension direction of the hand placement part 14.
[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
