Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary medical equipment, and in particular relates to a walking aid for rehabilitation. Background Art

[0002] After surgery, patients, such as those with heart disease, can perform some active and passive exercises with the help of a nurse, and about a week after surgery, they can perform bedside exercises under the guidance of a nurse. As recovery progresses, patients may gradually perform indoor and outdoor exercises, which will help them restore their mobility and improve their physical tolerance. However, due to their physical weakness, they may feel weak or even fall when getting out of bed and walking, so they need to use some equipment to assist them in walking.

[0003] Currently, people use walkers to assist with walking. However, during use, the height of existing walkers cannot be adjusted, and the optimal state is to keep the handle of the walker flush with the wrist. Therefore, existing walkers cannot meet the needs of patients of different heights to maintain the optimal use state, resulting in inconvenience. Moreover, when moving with a walker, the patient is located within the frame of the walker and then moves the walker. During the movement, the walker is not easy to move too far. If it moves too far, it is easy to slide and fall. The movement of the walker depends on the patient's own control and there is no specific reference standard. Since most patients are using a walker for the first time and have no experience, they may be afraid, which also affects their use. In order to ensure the comfort of patients, existing walkers are covered with rubber covers on the handles of the walkers. However, existing walkers are all fixed and integrated structures. If the rubber covers are damaged during use or sweat a lot, they cannot be replaced. Utility Model Content

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.

[0022] A walking aid device for rehabilitation described in this embodiment, as shown in Figure 1 、 Figure 2 and Figure 3 , includes two horizontally arranged and parallel fixed rods 1. The two fixed rods 1 are parallel front and back. Fixed tubes parallel to them are arranged above both fixed rods 1. Support rods 3 are vertically fixed between the fixed rods 1 and the fixed tubes. Two support rods 3 are vertically arranged between the fixed rod 1 and the fixed tube on the same side. The bottom end of the support rod 3 is fixed to the top of the fixed rod 1, and the top end of the support rod 3 is fixed to the bottom of the fixed tube. The fixed tube is supported by the support rod 3.

[0023] A first connecting rod is horizontally fixed between the same ends of the two fixed rods 1. The left ends of the two fixed rods 1 are connected by the first connecting rod. The first connecting rod and the two fixed rods 1 as a whole form a "C" - shaped structure. A second connecting rod is horizontally fixed between the two fixed tubes above the first connecting rod. The second connecting rod is located at the left end of the fixed tube. The overall structure of the second connecting rod and the fixed tube is the same as the overall structure of the first connecting rod and the fixed rod 1. The fixed rod 1 is a tubular structure. Movable rods 2 are movably arranged inside both fixed rods 1, enabling the movable rods 2 to horizontally move inside the fixed rods 1.

[0024] The movable rod 2 is a screw rod, and the inner side wall of the fixed rod 1 is provided with an internal thread that is threadedly matched with the movable rod 2. Through the threaded match between the movable rod 2 and the fixed rod 1, the fixed rod 1 and the movable rod 2 are movable and matched, and the movable rod 2 is also moved horizontally. Of course, in some embodiments, the movable rod 2 can also be independently installed in the fixed rod 1, and a first bolt is provided on the fixed rod 1 for fixing it to the movable rod 2. A first threaded hole is provided on the side wall of the right end of the fixed rod 1. The screw of the first bolt passes through the first threaded hole and presses against the movable rod 2, thereby fixing the movable rod 2 in the fixed rod 1. This section as a whole makes the movable rod 2 movable in the fixed rod 1.

[0025] A fixed block 10 is fixed to the end of one of the movable rods 2. The fixed block 10 is a rectangular block. A connecting rod 17 is fixed to the end of the other movable rod 2. The fixed block 10 is fixed to the right end of the front movable rod 2. The connecting rod 17 is fixed to the right end of the rear movable rod 2. The length direction of the connecting rod 17 is consistent with the length direction of the rear movable rod 2. The outer wall of the connecting rod 17 is provided with an external thread. The side wall of the fixed block 10 is provided with a thread groove for inserting the connecting rod 17 and threadedly fitting. The thread groove is provided on the rear side wall of the fixed block 10. Through the threaded fit of the connecting rod 17 and the fixed block 10, the two movable rods 2 are connected vertically. The content of this paragraph as a whole constitutes an adjustment mechanism for adjusting the height of the fixed rod 1.

[0026] Of course, in some embodiments, the outer side of the connecting rod 17 is not provided with threads, and the rear side wall of the fixed block 10 is provided with a mounting groove for embedding the connecting rod 17. The connecting rod 17 is embedded in the mounting groove to connect the two movable rods 2.

[0027] A screw rod 13 is vertically provided at the bottom of the fixing rod 1, and two screw rods 13 are vertically provided at the bottom of the fixing rod 1 on the same side. A base is provided at the bottom of the screw rod 13, and a sleeve 12 is sleeved on the screw rod 13 and threadedly matched therewith. The inner side wall of the sleeve 12 is provided with an internal thread that threadedly matches the screw rod 13. The top of the sleeve 12 is independently sleeved with a first sleeve 11, and the top end of the first sleeve 11 is fixed to the fixing rod 1. The top end of the first sleeve 11 is fixed to the fixing rod 1 through a horizontally arranged fixing plate 9. The fixing plate 9 increases the contact area with the bottom of the fixing rod 1, so that the fixing effect is better.

[0028] The tops of the first sleeve 11 and the sleeve 12 are each provided with a through hole communicating with the inside and outside. The through hole is passed through by a bolt, and a nut is provided on the screw rod of the bolt to threadably engage with the bolt. The first sleeve 11 is located between the nut cap and the nut of the bolt, and is inserted into the through hole by the screw rod of the bolt to prevent the first sleeve 11 from sliding downward, so that the sleeve 12 supports the first sleeve 11 and the fixed rod 1. Of course, when the first sleeve 11 and the sleeve 12 are fixed, the top of the sleeve 12 is spaced from the top of the first sleeve 11, leaving a gap for the sleeve 12 to move up and down within the first sleeve 11. Of course, in some embodiments, it is also possible that the first sleeve 11 and the sleeve 12 do not have through holes or nuts. The first sleeve 11 has a threaded hole threadedly engaged with the bolt, and the screw rod of the bolt passes through the threaded hole in the first sleeve 11 and presses against the sleeve 12, thereby fixing the sleeve 12 within the first sleeve 11. The content of this section as a whole constitutes a locking assembly that fixes the first sleeve 11 and the sleeve 12.

[0029] The above two sections constitute a connecting mechanism that connects the two movable rods 2 in a vertical shape. When in use, to adjust the height of the fixed rod 1, first loosen the bolts on the two first sleeves 11 on the first diagonal, such as loosening the bolts on the first sleeve 11 on the right side of the front fixed rod 1 and the first sleeve 11 on the left side of the rear fixed rod 1. Because the fixed rod 1 is supported by the other two first sleeves 11 on the second diagonal, the fixed rod 1 will not fall. Then rotate the sleeve 12 on the first diagonal so that the sleeve 12 on the first diagonal is at the same level as the sleeve 12 on the first diagonal. Move up and down in the first sleeve 11 of the first diagonal corner to make the two sleeves 12 of the first diagonal corner consistent in height. After adjustment, loosen the bolts on the first sleeve 11 of the second diagonal corner. At this time, the fixing rod 1 can be moved up and down, and then the first sleeve 11 and sleeve 12 of the first diagonal corner are fixed. The sleeve 12 of the second diagonal corner is rotated to adjust the height of the sleeve 12 of the second diagonal corner, and then the sleeve 12 of the second diagonal corner is fixed to the first sleeve 11 to support the fixing rod 1, thereby completing the adjustment of the height of the fixing rod 1.

[0030] Of course, in some embodiments, the adjustment mechanism can also be such that the screw rod 13 is a fixed rod, the sleeve 12 is sleeved on the fixed rod, a bolt is provided on the sleeve 12, and the top of the sleeve 12 is fixed to the bottom of the fixed rod 1.

[0031] The base includes a vertically arranged bottom column 15, and the outer side of the bottom column 15 is wrapped with an anti-slip cover 16. The anti-slip cover 16 is a trough structure. The anti-slip cover 16 wraps the side wall and bottom of the bottom column 15. The anti-slip cover 16 is made of rubber and plays an anti-slip role.

[0032] The outer side of the sleeve 12 is independently sleeved with a second sleeve 14, and the diameter of the bottom column 15 is consistent with the outer diameter of the second sleeve 14, so that the bottom column 15 blocks the sliding of the second sleeve 14 and prevents the second sleeve 14 from sliding out from the bottom of the screw 13. The second sleeve 14 can surround the screw 13 exposed below the sleeve 12, thereby preventing the threads of the screw 13 below the sleeve 12 from being exposed to the air, thereby protecting the threads on the screw 13; of course, in order to increase stability, a reinforcing rod is fixed horizontally between the second sleeves 14 on the same side, and a reinforcing rod is fixed horizontally between the second sleeves 14 on the left side. In order to control the movement of the sleeve 12, the outer wall of the sleeve 12 is provided with scale lines, and the top of the second sleeve 14 is the reference standard for the scale lines on the outer side of the sleeve 12. When the sleeve 12 rotates, the height of the sleeve 12 is controlled by the position where the scale lines on the outer side of the sleeve 12 are aligned with the second sleeve 14, so that all sleeves 12 are at the same height.

[0033] The fixing tube is covered with a protective cover 8, which is made of rubber. Of course, the protective cover 8 can also be made of sponge. The protective cover 8 can reduce direct contact between the patient's hand and the fixing tube, thereby reducing discomfort.

[0034] The fixed tube includes two first fixed tubes 4 that are horizontally arranged and independent of each other, a second fixed tube 7 is horizontally arranged between the two first fixed tubes 4, a protective sleeve 8 is sleeved on the second fixed tube 7, the inner diameter of the second fixed tube 7 is consistent with the inner diameter of the first fixed tube 4, and a connecting rod 6 is movably arranged in the first fixed tube 4, one end of the connecting rod 6 is inserted into the second fixed tube 7 to support the second fixed tube 7, the connecting rod 6 is a screw, and the inner side walls of the second fixed tube 7 and the first fixed tube 4 are provided with an internal thread that is threadedly matched with the connecting rod 6, and the connecting rod 6 is connected to the second fixed tube 7. The threaded fit of the fixed tube 7 and the first fixed tube 4 constitutes a fixing assembly that fixes the first fixed tube 4 to the connecting rod 6. Of course, in order to control the moving distance of the connecting rod 6 in the second fixed tube 7 and to facilitate the rotation of the connecting rod 6, the end of the connecting rod 6 away from the second fixed tube 7 extends beyond the first fixed tube 4 and is fixed by a limit block 5. The limit block 5 is a circular plate, and the inner diameter of the first fixed tube 4 is smaller than the diameter of the limit block 5. Of course, in some embodiments, the fixing assembly can also be a bolt, which fixes the connecting rod 6 in the first fixed tube 4. When the connecting rods 6 in the two first fixed tubes 4 are both located in the second fixed tube 7, the connecting rod 6 supports the second fixed tube 7. When the second fixed tube 7 is to be removed, the connecting rod 6 is removed from the second fixed tube 7. When the second fixed tube 7 is detached, the protective cover 8 can be replaced.

[0035] The outer diameter of the protective sleeve 8 is consistent with the outer diameter of the first fixed tube 4, and the outer diameter of the second fixed tube 7 is smaller than the outer diameter of the first fixed tube 4. When the protective sleeve 8 is put on the second fixed tube 7, the outer wall of the protective sleeve 8 is flush with the outer wall of the first fixed tube 4, so that the two first fixed tubes 4 can block the horizontal sliding of the protective sleeve 8.

[0036] Working principle:

[0037] When in use, when the height of the fixed rod 1 is to be adjusted according to the height of the patient, the sleeve 12 and the first sleeve 11 are loosened, and then the sleeve 12 is rotated to adjust the combined length of the sleeve 12 and the screw 13. After the adjustment, the sleeve 12 and the first sleeve 11 are fixed to complete the adjustment of the height of the fixed rod 1, so that the patient is in a more comfortable state when holding the protective cover 8. Then, the patient is positioned between the right ends of the two fixed rods 1, and then the rear movable rod 2 is completely pulled out from the rear fixed rod 1, and then the front movable rod 2 is pulled to the right so that the right end of the front movable rod 2 exceeds the patient, and then the rear movable rod 2 is vertically connected to the front movable rod 2 so that the rear movable rod 2 is parallel to the patient, and the distance between the rear movable rod 2 and the patient is adjusted by sliding the front movable rod 2. The distance between the rear movable rod 2 and the patient is the maximum distance the patient can move at one time. Then, the patient holds the protective cover 8 and moves the fixed rod 1 to the left. The movement of the fixed rod 1 drives the movable rod 2 to move. When the rear movable rod 2 contacts the patient, the patient knows that the movement distance has reached the maximum, so that the rear movable rod 2 limits the movement of the fixed rod 1. At the same time, it provides the patient with a reference for the movement distance, which is also a limit. The patient can control the movement distance of the fixed rod 1, preventing him from falling after moving too far at one time, reducing the psychological pressure of the patient during walking exercise, and facilitating use. After use, the rear movable rod 2 is removed from the front movable rod 2 and placed in the rear fixed rod 1. It is convenient to place and store.
