[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0026] As described in the background section, in the field of medical rehabilitation, walking aids are crucial for promoting patients' ability to walk and improving their quality of life. Traditional walking aids, such as canes and walking frames, can help patients support their weight and maintain balance to some extent, but they still have some limitations in actual use, especially for patients who have just undergone surgery or are in the early stages of rehabilitation, whose walking ability has not yet fully recovered and are often accompanied by a higher risk of falls.
[0027] To solve this technical problem, this utility model provides a walking assistance device.
[0028] For details, please refer to Figures 1-4 The walking assistance device specifically includes:
[0029] The base frame 1 has several wheels 101 at its bottom and a vertical plate 102 fixedly installed on its top. A first adjusting member is provided between the vertical plate 102 and the wheels 101. The first adjusting member is connected to a protective ring 106. A limit ring 107 is inserted into the inner wall of the protective ring 106. A support ring 108 is fixedly installed on the top of the limit ring 107. A flexible ring 109 is fixedly installed on the top of the support ring 108.
[0030] The walking assistance device provided by this utility model, through the setting of the protective ring 106, can protect the upper torso of the patient, which can effectively reduce the chance of the patient falling when walking and provide a safer rehabilitation environment for the patient.
[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] Example 1, please refer to Figures 1-4 A walking assistance device includes a base frame 1, with a plurality of wheels 101 at the bottom of the base frame 1, and a vertical plate 102 fixedly installed on the top of the base frame 1. A first adjusting member is provided between the vertical plate 102 and the wheels 101, and a protective ring 106 is connected to the first adjusting member. A limiting ring 107 is inserted into the inner wall of the protective ring 106, and a support ring 108 is fixedly installed on the top of the limiting ring 107. A flexible ring 109 is fixedly installed on the top of the support ring 108. The protective ring 106 can protect the upper torso of the patient, effectively reducing the chance of falls when the patient walks and providing a safer rehabilitation environment for the patient. The flexible ring 109 is made of rubber, which can improve the comfort of the user.
[0035] Furthermore, such as Figure 4 As shown, a limiting hole 110 is provided on the protective ring 106, and a limiting rod 111 is inserted into the limiting hole 110. The top end of the limiting rod 111 is fixedly connected to the support ring 108. The limiting rod 111 and the limiting hole 110 cooperate with each other to limit the support ring 108, so as to prevent the support ring 108 and the flexible ring 109 from rotating, thereby improving the stability of the flexible ring 109 during use.
[0036] Example 2 further optimizes the walking assistance device provided in Example 1, specifically, as follows: Figures 1-3As shown, the first adjusting component includes a side groove 103 formed on the side of the upright plate 102. A first lead screw 104 is connected to the side groove 103 via a bearing. A connecting plate 105 is threaded onto the outer surface of the first lead screw 104. One side of the connecting plate 105 is fixedly connected to the protective ring 106. During the rotation of the first lead screw 104, the limiting ring 107 can be moved up and down through the connecting plate 105, thereby adjusting the position of the protective ring 106 according to the user's height, so that the protective ring 106 is located in the patient's abdominal area.
[0037] Furthermore, such as Figures 1-3 As shown, a protective box 114 is installed between the back of the base frame 1 and the upright plate 102. The protective box 114 is connected to the side groove 103. A worm is installed inside the protective box 114 through a bearing. The worm is connected to a worm wheel 113. The worm wheel 113 is fixedly sleeved on the outer surface of the first lead screw 104. When the worm rotates, it can drive the first lead screw 104 to rotate through the worm wheel 113.
[0038] Furthermore, such as Figure 2 As shown, one end of the worm gear extends out of the protective box 114 and is fixedly connected to a first handwheel 112. The first handwheel 112 facilitates the rotation of the worm gear.
[0039] Furthermore, such as Figure 1 As shown, guide rails 2 are fixedly installed on both sides of the upright plate 102. Support arms 201 are slidably connected to the outer surfaces of the two guide rails 2. A support plate 202 is fixedly connected to one end of the support arm 201. A grip bar 203 is fixedly installed on the top of the support plate 202. The support plate 202 provides support for the user's arm, while the grip bar 203 provides grip for the user's hand.
[0040] Furthermore, such as Figure 2 As shown, a connecting arm 207 is fixedly connected between the two support arms 201. The connecting arm 207 can connect the two support arms 201 together so that the two support arms 201 can be raised and lowered synchronously.
[0041] Example 3 further optimizes the walking assistance device provided in Example 1 or 2, specifically, as follows: Figure 1 As shown, a second adjusting component is provided between the base frame 1 and the guide rail 2. The second adjusting component is connected to one of the support arms 201. The second adjusting component can adjust the height of the support arm 201 to meet the usage needs of users of different heights.
[0042] Furthermore, such as Figure 1As shown, the second adjusting component includes a support base 204 fixedly installed on the side of the upright plate 102. The support base 204 and the base frame 1 are connected by a second lead screw 205 through a bearing. The outer surface of the second lead screw 205 is threadedly connected to one of the support arms 201. By rotating the second lead screw 205, the support arm 201 connected to it can be driven to rise and fall, thereby achieving synchronous rising and falling of the two support arms 201 under the action of the connecting arm 207.
[0043] Furthermore, such as Figure 1 As shown, a second handwheel 206 is fixedly installed at the top of the second lead screw 205, and the second lead screw 205 can be driven to rotate by the second handwheel 206.
[0044] The usage process of the walking assistance device provided by this utility model is as follows:
[0045] During rehabilitation training for patients, the caregiver or medical staff turns the second handwheel 206, which drives the second lead screw 205 to rotate. During the rotation of the second lead screw 205, the support arm 201 connected to it is raised and lowered. Then, under the action of the connecting arm 207, the two support arms 201 are moved to the highest position. Then, the first handwheel 112 is turned so that the connecting plate 105 drives the protective ring 106 to the highest position. After the patient stands in the base frame 1, the first handwheel 112 is turned so that the protective ring 106 is lowered so that the protective ring 106 is aligned with the patient's abdominal area. The caregiver or medical staff turns the second handwheel 206 so that the support arm 201 is lowered to adjust the position of the support plate 202. Then, the patient places his arm on the support plate 202 to start the exercise.
