Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, and particularly relates to a walking assistance device for postoperative use. Background Art

[0002] After traumatic surgeries on patients' lower limbs, buttocks and other parts, walking exercises are required to prevent wound adhesion and promote muscle function recovery. When performing walking exercises, a walking assistance device is often needed. With the help of the walking assistance device, patients can walk by themselves without the need for others to support them, increasing the freedom of movement and rehabilitation of patients and reducing the workload of caregivers.

[0003] Existing walking assistance devices generally include a frame structure for holding, rollers at the bottom of the frame structure, and a foldable seat for rest. They have the advantage of simple structure. During use, patients mainly rely on the force of their hands to support and push the assistance device to reduce the difficulty of walking with the lower limbs. However, the heights of both the armrests and the foldable seat cannot be adjusted. For people of different heights, the most labor-saving height when grasping the armrests to exert force with the hands is different. Therefore, the non-adjustable armrests and seats make it inconvenient for some people to exert force and rest.

[0004] Therefore, a walking assistance device for postoperative use is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a walking assistance device for postoperative use to solve the problems mentioned in the above background art.

[0026] As Figures 1 to 5 shown, a postoperative walking assistance device includes a rear column 1 and a front column 2 arranged front and rear. The number of both the rear column 1 and the front column 2 is two. A connecting column 3 is fixedly connected between the opposite surfaces of the rear column 1 and the front column 2. Rollers 4 are rotatably installed at the bottom surfaces of the rear column 1 and the front column 2. A connecting plate 5 is fixedly installed between the opposite surfaces of the left and right rear columns 1. A lifting block 6 is slidably connected inside the rear column 1 and the connecting plate 5. A lifting mechanism 7 for driving the lifting of the lifting block 6 is provided on the surfaces of the rear column 1 and the connecting plate 5. Armrests 8 are fixedly installed at both left and right ends of the front surface of the lifting block 6. An auxiliary stability component 10 is provided on the surface of the front column 2. A folding seat 11 is fixedly connected to the bottom surfaces of the two armrests 8. A rubber sleeve 9 is fixedly sleeved on the side surface of the armrest 8.

[0027] More specifically, the lifting mechanism 7 drives the lifting of the lifting block 6, and then the armrest 8 fixedly installed on the surface of the lifting block 6 and the folding seat 11 fixedly installed on the surface of the armrest 8 are lifted, so that the heights of the armrest 8 and the folding seat 11 can be quickly adjusted. By adjusting the height of the armrest 8, the hand support requirements of patients with different heights during walking can be adapted, making walking more labor-saving. By adjusting the height of the folding seat 11, the patient can sit down more quickly and easily, and can meet the walking assistance and rest requirements of different patients. The auxiliary stability component 10 further strengthens the armrest 8 to ensure that the armrest 8 remains stable and horizontal while smoothly lifting. The foldable folding seat 11 is convenient for the patient to rest when tired. The rubber sleeve 9 is used to increase the friction force on the surface of the armrest 8, making the grip more firm.

[0028] The lifting mechanism 7 includes a double-port chute 701 and a threaded rod 702. The double-port chute 701 is opened on the surface of the rear column 1. The double-port chute 701 is internally connected to the connecting plate 5. The lifting block 6 is slidably installed on the inner wall surface of the connecting plate 5 and the inner wall surface of the double-port chute 701. The threaded rod 702 is rotatably installed on the bottom surface of the inner wall of the connecting plate 5. The threaded rod 702 penetrates through the top wall of the connecting plate 5 and is rotatably provided. A knob 703 is fixedly installed on the top surface of the threaded rod 702. The lifting block 6 is threadedly installed on the surface of the threaded rod 702.

[0029] Specifically, rotating the knob 703 drives the threaded rod 702 to rotate, causing the lifting block 6, which is threadedly installed on the surface of the threaded rod 702 and slidably installed inside the connecting plate 5 and on the inner wall surface of the double-port chute 701, to move up and down. This further drives the two armrests 8 fixedly installed on the front of the lifting block 6 to move up and down synchronously. At the same time, the folding seat 11 fixedly installed on the bottom surface of the armrest 8 is lifted, enabling flexible adjustment of the heights of the armrest 8 and the folding seat 11.

[0030] The auxiliary stability component 10 includes a single-port chute 101 and a sliding column 102. The single-port chute 101 is opened on the back surface of the front column 2, and the sliding column 102 is fixedly installed between the top and bottom surfaces of the inner wall of the single-port chute 101. The armrest 8 is slidably sleeved on the surface of the sliding column 102 and is slidably arranged relative to the inner wall surface of the single-port chute 101.

[0031] Specifically, through the cooperation of the single-port chute 101 and the sliding column 102, the armrest 8 remains horizontal during lifting, and the single-port chute 101 and the sliding column 102 are used to disperse the inclined stress received by the armrest 8, keeping the armrest 8 stable.

[0032] The folding seat 11 includes a fixing plate 111. The fixing plate 111 is fixedly installed at the rear side of the bottom surfaces of the two armrests 8. A storage groove 112 is opened on the front surface of the fixing plate 111. A rotating shaft 113 is rotatably installed between the left and right side surfaces of the inner wall of the storage groove 112. The rotating shaft 113 is arranged on the lower surface of the storage groove 112. A supporting plate 114 is fixedly installed on the surface of the rotating shaft 113. An auxiliary support component 12 is provided on the bottom surface of the supporting plate 114. An anti-falling component 13 is provided on the front surface of the fixing plate 111. The connecting plate 5 partially overlaps with the storage groove 112.

[0033] Specifically, the connecting plate 5 and the anti-falling component 13 are used to limit the supporting plate 114 that is in a vertical state and stored in the storage groove 112, preventing the supporting plate 114 from rotating forward or backward and affecting the normal walking of the patient. When the supporting plate 114 is needed, the anti-falling component 13 can be toggled to rotate the supporting plate 114 forward to a horizontal state, and the auxiliary support component 12 is used to further support the supporting plate 114 to ensure the stability of the supporting plate 114. When the connecting plate 5 drives the lifting block 6 to move up and down, the folding seat 11 will move up and down accordingly, and then the supporting plate 114 can be adjusted to a suitable height for the patient to sit.

[0034] The auxiliary support component 12 includes a receiving cavity 121. The receiving cavity 121 is opened on the bottom surface of the supporting plate 114. A limiting block 122 is slidably installed on the inner wall surface of the receiving cavity 121. A pressing plate 123 is fixedly installed on the bottom surface of the limiting block 122. The pressing plate 123 is slidably inserted into the bottom surface of the supporting plate 114, and the back surface of the pressing plate 123 is attached to the front surface of the fixing plate 111.

[0035] Specifically, when the supporting plate 114 rotates to the horizontal state, the limiting block 122 and the abutting plate 123 slide downward under the action of gravity, so that the abutting plate 123 extends out from the bottom surface of the supporting plate 114, and the back surface of the abutting plate 123 fits against the front surface of the fixing plate 111. When the patient sits down, the abutting plate 123 and the fixing plate 111 press against each other to form an auxiliary support for the supporting plate 114, making the supporting plate 114 more stable and reliable. After the supporting plate 114 rotates to the vertical state, the abutting plate 123 can be pushed back into the receiving cavity 121 again, so that there is no protrusion on the front surface of the supporting plate 114, which is safer in use.

[0036] The anti-falling component 13 includes a plug rod 131. The plug rod 131 is fixedly installed on the front surface of the fixing plate 111 and is located directly above the receiving groove 112. A blocking block 132 is rotatably installed on the surface of the plug rod 131. When the blocking block 132 hangs naturally, it protrudes from the top surface of the inner wall of the receiving groove 112.

[0037] Specifically, after the supporting plate 114 is in the vertical state, the blocking block 132 hangs naturally, and can contact the surface of the supporting plate 114 and prevent it from rotating forward. When the supporting plate 114 needs to be used, the blocking block 132 is rotated to the horizontal state, and the blocking block 132 can no longer block the rotation of the supporting plate 114. At this time, the supporting plate 114 can be rotated to the horizontal state.

[0038] In summary: The lifting mechanism 7 drives the lifting block 6 to lift, and further makes the armrest 8 fixedly installed on the surface of the lifting block 6 and the folding seat 11 fixedly installed on the surface of the armrest 8 lift, so that the height of the armrest 8 and the folding seat 11 can be quickly adjusted. By adjusting the height of the armrest 8, the hand support requirements of patients with different heights during walking can be adapted, making walking more labor-saving. By adjusting the height of the folding seat 11, the patient can sit down more quickly and easily, and can meet the walking assistance and rest needs of different patients.
