Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation technology, specifically a walking weight transfer training device for hemiplegic patients. Background Technology

[0002] Hemiplegia is a common condition caused by brain injury or other neurological diseases, resulting in impaired motor function on one side of the body. It severely affects patients' daily living activities and quality of life. Restoring walking ability is one of the key goals in the rehabilitation process for hemiplegic patients, and weight transfer training is an important component of walking training. During normal walking, the body's center of gravity shifts rhythmically between the left and right lower limbs. Hemiplegic patients, due to impaired strength, coordination, and proprioception in the affected limb, find it difficult to effectively complete this weight transfer, thus affecting the stability and smoothness of their gait.

[0003] Existing gait training aids, such as ordinary walking aids, primarily focus on providing body support and assisting walking, and are not particularly targeted at weight transfer training. Patients often find it difficult to precisely control the amplitude and angle of weight transfer during use, thus failing to effectively stimulate the neuromuscular function recovery of the affected limb. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a walking weight transfer training device for hemiplegic patients.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] The walking weight transfer training device for hemiplegic patients includes a top plate, a hanger installed at both ends of the top plate, a horizontal arm installed at the lower part of the hanger, sleeves rotatably installed at both ends of the horizontal arm, and a support frame with both ends connected to the sleeves on the same side of the horizontal arm.

[0007] The bottom of the hanger is provided with a torsion hole, and the top of the cross arm is installed in the torsion hole through a torsion bar; the hanger is slidably installed with a limit block, and the bottom end of the limit block protrudes from the top of the torsion hole through a limit head;

[0008] The upper part of the torsion bar has a limiting groove, which cooperates with the limiting head; the two sides of the limiting head are engaged with the groove wall of the limiting groove, and the two sides of the limiting head have at least three sets of mutually inclined inclined surfaces.

[0009] Preferably, the inclined surfaces on both sides of the limiting head are respectively set as inclined surface one, inclined surface two, and inclined surface three from top to bottom, and the angles between inclined surface one, inclined surface two, and inclined surface three and the horizontal direction gradually decrease.

[0010] Preferably, the cross-section of the limiting groove is set as a trapezoidal surface, and the inclination angle of the inclined surface is the same as the inclination angle of the side of the limiting groove.

[0011] Preferably, the hanger has a movable groove embedded inside, the limiting block is embedded in the movable groove, and the bottom of the hanger is set as an inverted trapezoidal connector; the movable groove has sliding grooves on both sides, and the limiting block is locked in the sliding grooves by limiting pins on both sides; the limiting pin is fitted with a locking nut by a threaded structure.

[0012] Preferably, the torsion bar is located at the middle position of the upper part of the cross arm, and the length direction of the torsion bar is perpendicular to the length direction of the cross arm; clamps are provided on both sides of the torsion bar, the clamps are attached to both sides of the bottom end of the hanger, and the lower part of the clamps is fixedly connected to the cross arm through a connecting plate.

[0013] Preferably, the upper part of the connecting plate is configured as a trapezoidal structure, and a reinforcing plate is provided between the connecting plates on both sides of the hanger, the reinforcing plate being fixedly connected to the cross arm.

[0014] Preferably, the two ends of the cross arm are provided with rotating seats, the end of the sleeve is mounted on the rotating block through a rotating shaft, and the rotating block is rotatably connected to the rotating seat through a rotating head; the two ends of the support frame are bent and provided with connecting rods, and the connecting rods are connected to the screw cylinder through a threaded structure.

[0015] Preferably, a bottom plate is provided at the lower part of the top plate, and the bottom plate is fixedly connected to the top plate by uprights; the corners of the bottom plate are provided with chamfered structures.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. It can provide necessary body support for patients when they are walking; and the rotational connection between the cross arm and the hanger, as well as the angle limitation through the limiting block and the limiting groove, enable patients to safely and effectively transfer their center of gravity within the set angle range when moving their center of gravity with the support frame. This helps to stimulate the recovery of neuromuscular function of the affected limb in hemiplegic patients and improve their walking ability and balance control.

[0018] 2. It can help patients actively shift their center of gravity while walking, reducing their fear. For patients who are afraid of shifting their center of gravity and bearing weight on the affected side, it can better observe whether the patient has fully shifted their center of gravity.

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Example

[0029] like Figure 1 As shown, the walking weight transfer training device for hemiplegic patients includes a base plate 2 and a top plate 1 installed on the base plate 2; the top plate 1 is equipped with hangers 3 at both ends, and a rotatable horizontal arm 4 is installed at the lower part of the hanger 3. Two support frames 6 are installed at both ends of the horizontal arm 4 through sleeves 5.

[0030] The main function of the support frame 6 is to provide support for the user during use. When in use, the support frame 6 is held under the patient's armpit. When the patient's center of gravity shifts while walking, they will lean to one side, which will suppress the support frame 6 on the corresponding side to rotate downward. At the same time, one end of the horizontal arm 4 connected to the support frame 6 will deflect downward, while the other end will tilt upward, thereby causing the support frame 6 connected to the corresponding end to flip upward, thus supporting the user's arm and providing support. This protects the user's safety during training. Safe training helps to stimulate the recovery of neuromuscular function in the affected limb of hemiplegic patients, and improve their walking ability and balance control.

[0031] Please see Figures 3-5 A limiting block 7 is slidably installed in the hanger 3. The position of the limiting block 7 can be adjusted so that the limiting head 71 at its bottom end can engage with different sizes in the limiting groove 42 of the torsion bar 41. When the limiting head 71 is engaged with a smaller size, the gap between the limiting groove 42 and the limiting head 71 is larger. This allows the limiting head 71 to engage with the limiting groove 42 when the torsion bar 41 rotates at a larger angle, thus achieving the purpose of limiting. As the size of the limiting head 71 engaged increases, the gap between the limiting groove 42 and the limiting head 71 decreases, thereby reducing the angle at which the torsion bar 41 can rotate. This method limits the rotation angle. By limiting the rotation angle, the deflection angle of the cross arm 4 can be limited, preventing excessive deflection angles that could lead to a fall and affect the user's health and safety.

[0032] The limiting block 7 moves in the movable groove 33 inside the hanger 3, and the two sides of the limiting block 7 pass through the sliding grooves 34 on both sides of the movable groove 33 via limiting pins 72. By adding a locking nut 73 to the limiting pin 72, the locking nut 73 can be locked against the hanger 3 through the thread, thereby locking the limiting block 7 to ensure its stable setting and providing a stable angle limiting function.

[0033] The twist hole 32 is provided in the bottom inverted trapezoidal connector 31. The inverted trapezoidal connector 31 can reduce the obstruction when the horizontal arm 4 rotates, and avoid restricting the rotation of the horizontal arm 4.

[0034] Please see Figure 6The limiting head 71 is composed of symmetrical inclined surfaces with different inclination angles on both sides, specifically inclined surface 1 74, inclined surface 2 75, and inclined surface 3 76 from top to bottom. At the same time, the angles between inclined surface 1 74, inclined surface 2 75, and inclined surface 3 76 and the horizontal direction gradually decrease. The purpose of this setting is that the limiting head 71 corresponding to inclined surface 1 74, inclined surface 2 75, and inclined surface 3 76 has different ranges of angle change when moving the same size, thereby enriching the diversity of the adjustment of the limiting head 71. In addition, the inclination angle of inclined surface 1 74 is the same as the inclination angle of the side of the limiting groove 42, which can ensure that the torsion bar 41 can be locked after the limiting head 71 is fully inserted, thus ensuring the overall stability.

[0035] Please see Figure 2 The torsion bar 41 is clamped to the hanger 3 on both sides by clamping plates 43. The lower part of the clamping plates 43 is fixedly connected to the cross arm 4 by connecting plates 44. The upper part of the connecting plates 44 is set as a trapezoidal structure. The trapezoidal connecting plates 44 can increase the size of the bottom to provide a larger range to connect with the cross arm 4 and increase the connection strength between itself and the cross arm 4. Furthermore, a reinforcing plate 46 is provided between the connecting plates 44. The reinforcing plate 46 is also fixedly connected to the cross arm 4, which can further increase the connection strength between the cross arm 4 and the upper connecting plate 44, thereby making the overall structure more stable and more durable.

[0036] One end of the sleeve 5 is open and connected to the connecting rods 61 bent at both ends of the support frame 6 by threads. The length of the connecting rods 61 can be adjusted to adjust the height of the support frame 6 to suit users of different heights, so that users of different heights can have a good user experience and increase the applicability of the structure.

[0037] The other end of the sleeve 5 is connected to the rotating block 51 via a rotating shaft. The two can rotate around the rotating shaft, which facilitates the extension and relative rotation of the sleeve 5 and the connecting rod 61, enabling them to mesh and perform telescopic operations. The rotating block 51 is rotatably connected to the rotating seats 45 at both ends of the cross arm 4 via a rotating head 52. The sleeve 5 as a whole can rotate with the cross arm 4, thereby changing the state of the support frame 6 to meet the user's adjustment needs during normal use.

[0038] On the outside of the support frame 6, a thick sponge pad can be removed and placed on the outside in practical applications, thereby improving the user's experience when in contact with it and also having the function of preventing pressure sores.

[0039] The base plate 2 and the top plate 1 are connected by a vertical pole 21, and the base plate 2 is provided with a chamfered structure to reduce the size of the edge, making it easier for patients with mobility impairments to step onto the base plate 2.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
