Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation devices, in particular to a walking assistance device after cardiac surgery. Background Technique

[0002] The great saphenous vein is the longest superficial vein in the human body, extending from the ankle to the root of the thigh. Due to its small curvature, sufficient length, and relatively matching blood vessel caliber with the coronary artery, it is one of the most commonly used "bridge" blood vessel materials in coronary artery bypass grafting surgery. There are two sets of venous return systems in the lower extremities of the human body, namely deep veins and superficial veins, and there are relatively rich communicating collateral branches between them. After removing the superficial vein, that is, the great saphenous vein, after sufficient long-term recovery, the collateral circulation between the deep and superficial veins will become more abundant, playing a compensatory role, and will not have too much impact on the return of lower extremity venous blood, nor will it affect the motor function of the lower extremities. When performing coronary artery bypass grafting, most often the great saphenous vein in the leg is used as the bridge blood vessel material. Since the great saphenous vein is removed from the leg, the venous blood that originally needed to flow back through the great saphenous vein needs to flow back through the deep veins, and a new collateral circulation is established, which takes a period of time, usually several months.

[0003] During this period, the lower extremity from which the blood vessel is taken will have varying degrees of swelling, and the patient cannot walk normally. This requires the patient to often raise and lower the lower extremity to promote blood flow and eliminate swelling. At the same time, a massage belt is tied on for hot compress and massage (the massage belt is a device that can massage and relax different parts of the body) to promote the patient to resume normal walking as soon as possible. However, it is difficult for the patient who is physically weak just after discharge to raise and lower the lower extremity for a long time, which will make the patient feel very strenuous and is instead not conducive to the elimination of lower extremity swelling. For this reason, we propose a walking assistance device after cardiac surgery. Content of the Utility Model

[0018] Embodiment 1: Please refer to Figures 1 - 4 , a walking assistance device after cardiac surgery shown in the figure, including a chair frame 1 and a cushion 2 installed on the chair frame 1. A concave-shaped support plate 3 is hinged at the front edge of the lower end of the cushion 2. The middle part of the rear end of the concave-shaped support plate 3 is attached to a concave-shaped rod 4. The front end of the concave-shaped rod 4 is fixedly connected to the outer wall of the chair frame 1. The middle part of the rear end of the concave-shaped rod 4 is rotatably connected to a stud 15. A driving member is provided between the stud 15 and the chair frame 1. An internal thread ring 16 is threadedly sleeved on the rear edge of the outer wall of the stud 15. The top of the outer wall of the internal thread ring 16 is rotatably connected to a connecting rod 17. One end of the connecting rod 17 away from the internal thread ring 16 is rotatably connected to the upper edge of the rear end of the concave-shaped support plate 3. Rectangular plates 5 are symmetrically attached to the front ends of the concave-shaped support plate 3. A guiding component and an adjusting mechanism are respectively provided between the two rectangular plates 5 and the concave-shaped support plate 3. Massage belts 6 are fixedly installed at the front ends of the two rectangular plates 5.

[0019] Please refer to Figure 1 and Figure 2 , the driving member shown in the figure includes a connecting plate 12. The connecting plate 12 is fixedly connected to the rear edge of the outer wall of the chair frame 1. The lower edge of the front end of the connecting plate 12 is fixedly connected to a carrier plate 13. A motor 14 is fixedly installed on the upper end of the carrier plate 13. The output shaft end of the motor 14 is fixedly connected to the rear end of the stud 15.

[0020] In this embodiment, the patient can sit on the cushion 2 on the chair frame 1 and place the lower limbs at the front end of the concave-shaped support plate 3. Then, the massage belt 6 on the rectangular plate 5 is tied to the lower limb that needs to be massaged, and the massage belt 6 is started to massage the lower limb. Subsequently, the motor 14 on the carrier plate 13 is connected to an external power supply. The output shaft of the motor 14 will rotate and drive the stud 15 to rotate on the concave-shaped rod 4. The stud 15 will drive the internally threaded ring 16 to slide forward on the outer wall of the stud 15. During this process, the connecting rod 17 on the internally threaded ring 16 will also move forward and rotate on the internally threaded ring 16. The connecting rod 17 will drive the concave-shaped support plate 3 to rotate upward on the cushion 2 (the connecting rod 17 will also rotate on the concave-shaped support plate 3), and the concave-shaped support plate 3 can drive the patient's lower limb to be lifted. Similarly, when the motor 14 rotates in the reverse direction, the height of the patient's lower limb can be reset. As the motor 14 rotates forward and reverses continuously, the patient's lower limb can be continuously lifted and lowered to promote blood flow and eliminate swelling, without the patient relying on their own strength to lift and lower the lower limb.

[0021] Embodiment 2: Please refer to Figure 1 、 Figure 3 and Figure 4 , this embodiment further illustrates Embodiment 1. In the figure, the guiding component includes a T-shaped groove 7 and a T-shaped plate 18. The T-shaped plate 18 is fixedly connected to one side of the rear end of the rectangular plate 5 near the edge. The T-shaped groove 7 is opened at the front end of the concave-shaped support plate 3, and the T-shaped groove 7 and the T-shaped plate 18 are in sliding fit.

[0022] Please refer to Figures 1 - 4 , the adjusting mechanism includes a square plate 8 and a plurality of jacks 9. The square plate 8 is fixedly connected to the lower edge of the side wall of the rectangular plate 5 away from the T-shaped plate 18, and one side wall of the square plate 8 is in contact with the outer wall of the concave-shaped support plate 3. Another side wall of the square plate 8 is fixedly connected with a cylinder 10. An insertion post 19 is slidably inserted through the inner wall of the cylinder 10 and the square plate 8. A plurality of jacks 9 are linearly arranged from top to bottom on the outer wall of the concave-shaped support plate 3 corresponding to the insertion post 19. The uppermost jack 9 and the insertion post 19 are in sliding fit. An elastic member and a pulling member are respectively arranged between the insertion post 19 and the cylinder 10.

[0023] Please refer to Figure 3 , the elastic member includes an annular plate 20. The annular plate 20 is fixedly sleeved on the outer wall of the insertion post 19, and one side wall of the annular plate 20 is in contact with the side wall of the square plate 8. A spring 21 is fixedly connected between the other side wall of the annular plate 20 and the inner wall of the cylinder 10. The spring 21 is slidably sleeved on the outer wall of the insertion post 19.

[0024] Please refer to Figures 1 - 3 , the pulling member includes a pull block 11. The pull block 11 is fixedly connected to the end of the insertion post 19 away from the jack 9, and the side wall of the pull block 11 is in contact with the side wall of the cylinder 10.

[0025] In this embodiment, the lower limb swelling positions of different patients are different. When it is necessary to lower the position of the massage belt 6 to achieve precise massage, the pulling block 11 can be pulled. The pulling block 11 will drive the inserting post 19 to slide within the square plate 8 and the cylinder 10. The inserting post 19 will drive the annular plate 20 to slide within the cylinder 10 (during this process, the spring 21 between the annular plate 20 and the cylinder 10 will be compressed), and the inserting post 19 will also slide outward within the jack 9 on the corresponding concave supporting plate 3 and completely leave the jack 9.

[0026] Subsequently, while keeping the pulling block 11 pulled without releasing, the rectangular plate 5 is moved downward. The rectangular plate 5 will slide downward on the concave supporting plate 3 (during this process, the T-shaped plate 18 on the rectangular plate 5 will slide downward within the T-shaped groove 7 on the concave supporting plate 3), then the massage belt 6 can move downward together with the rectangular plate 5. When the massage belt 6 moves to a suitable position, release the pulling block 11. Then, under the action of the spring 21, the inserting post 19 will automatically reset and insert into another corresponding T-shaped groove 7 on the concave supporting plate 3, then the rectangular plate 5 can maintain a fixed state again after moving downward, and the massage belt 6 can maintain a fixed state again after moving downward, and the operation is simple.

[0027] It should be noted that this device enables patients to promote blood flow and eliminate swelling without relying on their own strength to lift and lower their lower limbs, reducing the burden on patients. While lifting and lowering the lower limbs, it can also massage the lower limbs. At the same time, the position of the massage belt 6 is adjustable and the massage position is precise, which is conducive to the elimination of lower limb swelling in patients and promotes the early recovery of patients' normal walking.

[0028] It should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
