Description

Technical Field

[0001] This utility model relates to the field of rehabilitation technology for stroke patients with hemiplegia, and in particular to a sitting balance rehabilitation device for stroke patients with hemiplegia. Background Technology

[0002] Theories of early stroke rehabilitation confirm that prolonged bed rest can impair a patient's potential for functional recovery, particularly neuromuscular and balance functions, reducing brain plasticity and functional reorganization. Clinically, stroke patients have a significantly higher incidence of falls than non-stroke patients due to balance impairment. Once a stroke patient's condition stabilizes, early bed-getting training and sitting exercises are crucial. The key feature of this training is maintaining a stable sitting position for a certain period, providing support to prevent falls in case of imbalance. Sitting balance training is an important component of early rehabilitation for hemiplegic patients. Timely and effective sitting balance training to prevent falls is crucial for successful rehabilitation.

[0003] Currently, there are two main rehabilitation programs for sitting balance training for stroke patients with hemiplegia: one is manual rehabilitation by therapists in the rehabilitation department; the other is sitting balance training using instruments in the rehabilitation room.

[0004] Both of the above approaches have shortcomings and cannot fully meet the rehabilitation needs of patients. The first approach does not consider human factors; rehabilitation therapists have limited time, thus restricting the time available for related training. There is also the possibility that therapists may be on leave, preventing the implementation of relevant manual therapy techniques. While the second approach provides some rehabilitation training, patients can only receive it in a dedicated rehabilitation room, and due to the large number of patients and limited equipment, there are waiting times for equipment. In short, neither approach considers the long stroke rehabilitation period, the fact that most patients need to return home, and the need for patients to perform seated balance rehabilitation anytime, anywhere, when their condition permits.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] Example 1: Combination Figure 1-3 This embodiment discloses a sitting balance rehabilitation device for stroke hemiplegic patients, which aims to solve the problem that some current rehabilitation methods fail to meet the needs of patients to perform sitting balance rehabilitation anytime and anywhere when their condition permits.

[0034] The rehabilitation training device specifically includes a seat body 1, an extension frame 2, a backrest 3, a seat belt 4, and support legs 5.

[0035] Among them, combined Figure 2The main body of the seat 1 is a horizontal plate structure used for patients to sit and perform seated balance rehabilitation training. Specifically, the main body of the seat 1 includes a support plate 11, with a mounting part 12 hinged to the rear end of the support plate 11. The mounting part 12 is connected and fixed to the bottom front side of the backrest 3, and a panel 13 is connected to the top of the support plate 11. It should be noted that the hinge structure between the support plate 11 and the mounting part 12 has an angle limiting function. During use, the panel 13 can lock in a horizontal posture. This is existing technology, and its specific structure and working principle will not be described in detail here. Those skilled in the art can select and implement it from existing technologies according to actual operating conditions.

[0036] In order to make the panel 13 have good breathability, the panel 13 is provided with a hollow groove 131, which runs through the panel 13 longitudinally.

[0037] The seat body 1 has a backrest 3 on the rear side. The backrest 3 provides back support for the patient when sitting. The backrest 3 is equipped with a safety belt 4 for wrapping around the patient's waist. The safety belt 4 is equipped with a buckle for easy wrapping around the patient's waist and abdomen for safety protection.

[0038] The backrest 3 is detachably connected to an extension frame 2, which is made of aluminum alloy profiles. When in use, it is mounted on the bed board. The side of the extension frame 2 away from the main seat 1 has a clamping structure for connecting to the bed frame, allowing the extension frame 2 to be locked and fixed to the bed frame. It should be noted that the outline of the extension frame 2 can be selected according to actual needs to meet the usage requirements of different bed frame structures.

[0039] Furthermore, the clamping structure includes an "L"-shaped claw 22. The vertical section of the claw 22 is slidably inserted into the end of the extension frame 2 away from the seat body 1. A fastening bolt 24 is threaded onto the side wall where the claw 22 connects to the extension frame 2. After the fastening bolt 24 is tightened, it can tightly abut against the claw 22, forming a locking and limiting structure for the claw 22 relative to the extension frame 2. This makes the locking operation of the extension frame 2 convenient and efficient. To improve the locking stability, the clamping end of the claw 22 is provided with an anti-slip structure, specifically an anti-slip plate 23.

[0040] In order to improve the load-bearing capacity of the seat body 1, the bottom of the seat body 1 is provided with height-adjustable support legs 5.

[0041] Furthermore, in order to improve the storage capacity of the device, a detachable snap-fit ​​structure is provided between the extension frame 2 and the seat body 1 to facilitate the assembly and disassembly of the two. In addition, the extension frame 2 is also provided with a hinge part 21 to facilitate flipping and folding, which can reduce the space occupied by the structure when not in use.

[0042] Example 2: Based on Example 1, combined with Figure 4As shown, the panel 13 is provided with two seat cushions 6 distributed on the left and right. The bottom of the seat cushion 6 is provided with a height adjustment structure, which allows for appropriate adjustment according to the patient's actual sitting balance control state during use. At the same time, the seat cushion 6 can also play an elastic cushioning role, improving the sitting comfort.

[0043] Furthermore, in combination Figure 5 As shown, the height adjustment structure includes a lifting screw 14 and a limiting nut 15. The limiting nut 15 and the support plate 11 are provided with left and right oriented track grooves 16. The limiting nut 15 can slide back and forth along the track grooves 16. A support plate 17 is provided between the top of the lifting screw 14 and the seat cushion 6. The cooperation between the track grooves 16 and the limiting nut 15 allows the position targeted by the height adjustment structure to slide left and right, realizing the height adjustment of the left or right side of the cushion. In use, the lifting screw 14 is turned from the bottom, and the lifting screw 14 can drive the cushion at its top to complete the lifting and lowering movement.

[0044] Furthermore, to enhance the functionality of the seat cushion 6, an elastomer is provided within the seat cushion 6. The elastomer is made of rubber, such as... Figure 6 As shown, the elastomer comprises a "D"-shaped structure consisting of a bottom layer 61 and a top layer 62. A support beam 63 is provided between the bottom layer 61 and the top layer 62. The elastomer provides suitable elastic support for the seat cushion 6. When sitting, the top layer 62 is compressed and sinks, and the support beam 63 bends accordingly to absorb some of the pressure, thereby providing suitable elastic support. In addition, auxiliary beams 64 are provided on both sides of the bottom layer 61 located on the support beam 63. The inner end of the auxiliary beam 64 is connected to the bottom layer 61, and the outer end of the auxiliary beam 64 is a free end facing the top layer 62. When compressed to a certain extent, the top layer 62 sinks and abuts against the auxiliary beam 64. The auxiliary beam 64 provides secondary support, making the rear elastic support have better support stability. Therefore, it balances softness and stability.

[0045] Example 3: Based on Example 1, combined with Figure 7 and Figure 8 As shown, armrests 7 are hinged to the left and right sides of the front of the seat body 1. The armrests 7 have a "D" shaped structure and are arranged symmetrically on the left and right sides. The bottom of the outer end of the armrest 7 is hinged to the left and right outer ends of the seat body 1, so that the armrests 7 can swing and be fixed in front of the patient when in use. This not only allows the patient to hold on, but also provides a protective structure in front of the patient when sitting.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
