Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a walking aid device for postoperative patients. Background Art

[0002] A postoperative walking aid device is a device that assists patients in their daily activities after surgery while performing leg rehabilitation training. It can support the movement of leg muscles through the correct mode to stimulate nerves, maintain or restore walking ability, enhance the coordination ability of the limbs, and getting out of bed and moving around has become one of the key measures for patients to reduce postoperative complications and accelerate recovery. However, patients are physically weak after surgery and need the support of medical staff when walking. Due to the shortage of hospital staff, it is impossible to assign one medical staff to each patient, so a walking aid device is needed.

[0003] However, in the prior art, when using a walking aid device, it is usually of a low structure, resulting in the patient having to bend down to hold it. Prolonged rehabilitation training will cause the patient's waist to ache, etc., and it is not easy to adapt to patients with a relatively tall height and lumbar diseases. Moreover, the structure is relatively simple, resulting in the patient having to walk to find a chair or stool to sit down and rest. Summary of the Invention

[0046] Specifically, the working process or principle of this postoperative patient walking aid is as follows: When in use, the patient enters the inner sides of the first middle frame 2 and the second middle frame 5, and wraps the shoulder strap 14 around the patient's shoulders. Then, rotate the first mounting plate 703 so that after rotation, the first mounting plate 703 is snapped into the clamping seat 702. Furthermore, the seat 11 can be rotated to the back of the patient, and the first top frame 1 and the second top frame 4 support the patient's armpits, facilitating the patient to hold onto the first middle frame 2 and the second middle frame 5, which is convenient for the patient to walk. When it is necessary to hang the infusion bag, rotate the first rotating disk 907, so that the first rotating disk 907 moves downward, enabling the first rotating disk 907 to drive the suspension frame 911 to move downward through the first mounting frame 910. Thus, it is convenient to hang the infusion bag on the suspension frame 911. And when the first rotating disk 907 moves downward, it can drive the first connecting plate 904 to move downward, causing the first connecting plate 904 to drive the first hanging hook 905 to move downward, thereby facilitating the hanging of the drainage bag. When the patient takes a rest after walking for a period of time, move the second moving plate 22, so that the second moving plate 22 drives the third pressing block 21 to move through the third moving rod 20, facilitating the third pressing block 21 to press the second pressed block 23, causing the second pressed block 23 to drive the fourth moving rod 24 to move, facilitating the fourth moving rod 24 to drive the fourth pressing block 25 to move. Furthermore, the fourth pressing block 25 presses the third pressed block 30, enabling the third pressed block 30 to drive the moving sleeve 29 and the connecting frame 33 to move, facilitating the connecting frame 33 to drive the pressing rod 32 to press the seat 11, causing the pressing rod 32 to push the seat 11, and enabling the seat 11 to tilt. While moving the second moving plate 22, the patient slowly squats down, so that the patient drives the pressing frame 13 to move downward through the shoulder strap 14, facilitating the pressing frame 13 to move downward to press the seat 11, and enabling the seat 11 to be pressed and flipped to the horizontal state, so that when the patient sits down, they can sit on the seat 11. Thus, it is convenient for the patient to rest after walking for a long time. And when it is necessary to brake the multiple rollers, push the first moving plate 803 forward, so that the first moving plate 803 drives the first pressing block 802 to press the first pressed block 804, causing the first pressed block 804 to drive the first brake block 807 to move downward through the second moving rod 805 and the second pressed block 23, facilitating the first brake block 807 and the first contact block 808 to move downward to fit with the rollers, and thus facilitating the braking of the rollers.
