Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical rehabilitation technology, specifically a gait training and rehabilitation device for Parkinson's patients. Background Technology
[0002] Parkinson's disease is a common neurodegenerative disease in the elderly, characterized by motor symptoms including resting tremor, bradykinesia, rigidity, and postural instability, which severely affect patients' ability to live independently. Among these symptoms, gait abnormalities are one of the main problems faced by Parkinson's patients, who often exhibit symptoms such as shorter strides, slower walking speed, difficulty initiating movement, and instability in balance while walking.
[0003] Effective gait training is crucial for improving motor function and quality of life in Parkinson's patients. Although existing technologies can provide some assistance for walking, Parkinson's patients may experience sudden postural imbalances during walking. Traditional devices cannot respond quickly enough to provide effective support, nor can they automatically adjust the support method according to the patient's stress, resulting in poor training outcomes. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a gait training and rehabilitation device for Parkinson's disease patients.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A gait training and rehabilitation device for Parkinson's patients includes a cylindrical rod for support and an annular sleeve fitted onto the cylindrical rod.
[0007] The annular sleeve has a handle on its side and an armpit support on its upper part.
[0008] The cylindrical rod is provided with a guide groove along its axial direction, a limit groove is provided on one side of the guide groove, and a locking pin is provided on the inner side of the annular sleeve to be engaged in the guide groove.
[0009] When the torque applied to the handle is greater than the torque applied to the armpit support, it causes the locking pin to flip towards the side of the guide groove opposite to the limiting groove; when the torque applied to the handle is less than the torque applied to the armpit support, it causes the locking pin to flip towards the side of the guide groove facing the limiting groove.
[0010] Preferably, the handle and the armpit support are located on opposite sides of the vertical plane containing the axis of the annular sleeve.
[0011] Preferably, a handle is mounted on the side of the annular sleeve via a bracket, and the handle is on the same horizontal plane as the axis of the annular sleeve when the locking pin engages with the limiting groove.
[0012] Preferably, the annular sleeve is provided with a mounting seat, and the lower part of the armpit support is connected to the mounting seat through a telescopic rod; the mounting seat is inclined upward when the locking pin engages with the side of the guide groove.
[0013] Preferably, the lower part of the cylindrical rod is provided with several sets of support legs, and the annular sleeve is provided with a notch; the notch is aligned with the top of the support leg when the locking pin engages with the side of the guide groove.
[0014] Preferably, the guide grooves are arranged in a circular array in at least two sets on the cylindrical rod, and each guide groove has at least two corresponding locking pins.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. When the patient applies significant force to the handle, the locking pin is in the guide groove and disengaged from the limiting groove, allowing the annular sleeve to move flexibly along the cylindrical rod. This design meets the dynamic support needs of patients during walking training, helps them train a natural gait, and enhances the coordination of the upper and lower limbs.
[0017] 2. When the patient's arm cannot exert sufficient force, i.e., when the axillary support is under significant stress, the locking pin and the limiting groove engage, fixing the position of the ring sleeve and preventing it from moving. This locking mechanism prevents the patient from continuing walking training when unable to support themselves, avoiding falls or muscle strains due to imbalance or fatigue, and significantly improving the safety of training.

[0025] 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.
[0026] Example
[0027] like Figure 1 , Figure 2 As shown, a gait training and rehabilitation device for Parkinson's patients includes a cylindrical rod 1 for support and an annular sleeve 2 fitted onto the cylindrical rod 1.
[0028] The cylindrical rod 1 provides the main vertical support for the entire device, and its evenly distributed support legs 11 ensure the stability of the device during use. The support legs 11 are in contact with the ground, which effectively distributes the weight of the device and the patient, preventing the device from tipping over during patient training.
[0029] like Figure 3 As shown, the annular sleeve 2 is fitted onto the cylindrical rod 1 and can move along the axial direction of the cylindrical rod 1. A handle 21 is mounted on the side of the annular sleeve 2 via a bracket 25, allowing the patient to grip the handle 21 during training for easier control of body balance and force application. When the locking pin 24 engages with the limiting groove 13, the handle 21 and the axis of the annular sleeve 2 are on the same horizontal plane. This design allows for a more reasonable point of force application when the patient grips the handle 21, reducing hand fatigue.
[0030] The cylindrical rod 1 has guide grooves 12 arranged along its axial direction, and the guide grooves 12 are arranged in a circular array, with at least two sets. Each guide groove 12 has a limiting groove 13 on one side, and the inner side of the annular sleeve 2 is provided with a corresponding locking pin 24 that engages in the guide groove 12, and at least two locking pins 24 are provided for each set of guide grooves 12. This design of multiple sets of guide grooves 12 and multiple locking pins 24 increases the stability and reliability of the movement of the annular sleeve 2, preventing the annular sleeve 2 from shifting or shaking during movement.
[0031] like Figure 4As shown, an axillary support 3 is provided on the upper part of the annular sleeve 2, providing additional support for the patient. The lower part of the axillary support 3 is connected to the mounting base 22 via a telescopic rod 31, and the mounting base 22 is set on the annular sleeve 2. When the locking pin 24 engages with the side of the guide groove 12, the mounting base 22 is tilted upwards. This angle design allows for a better fit under the patient's armpit, providing comfortable and effective support. The patient can adjust the height of the axillary support 3 by adjusting the length of the telescopic rod 31 to adapt to different physical conditions and training needs.
[0032] When a patient is undergoing gait training, if the lower limbs provide primary support and the hand exerts force normally, the torque on the handpiece 21 is greater than the torque on the armpit support 3, as shown in the diagram. Figure 1 As shown; at this time, the annular sleeve 2 is subjected to the force transmitted from the handle 21, which causes the locking pin 24 to flip towards the side of the guide groove 12 opposite to the limiting groove 13. At this time, the locking pin 24 is disengaged from the limiting groove 13 and is in the guide groove 12. The annular sleeve 2 can move flexibly on the cylindrical rod 1. The patient can freely adjust the position of the annular sleeve 2 according to the rhythm and movement of walking, thereby meeting the needs of walking exercise and achieving natural and smooth gait training.
[0033] When a patient's arms are weak or their lower limbs cannot provide sufficient support during training, the arm support is insufficient to maintain the patient's standing position. In this case, the force exerted on the armpit support 3 will increase, meaning the torque on the armpit support 3 will be greater than the torque on the handle 21, as shown in the diagram. Figure 2 As shown. At this time, under the force transmitted from the axillary support 3, the ring sleeve 2 causes the locking pin 24 to flip towards the side of the guide groove 12 facing the limiting groove 13. The locking pin 24 and the limiting groove 13 engage with each other, and the position of the ring sleeve 2 is immediately limited, preventing it from moving. This design can promptly prevent the patient from continuing to walk in an unstable state, effectively avoiding greater damage caused by the patient continuing to walk, and ensuring the patient's safety during training.
[0034] like Figure 5 As shown, the annular sleeve 2 has a notch 23. When the locking pin 24 engages with the side of the guide groove 12, the notch 23 aligns with the top of the support leg 11. This notch 23 design facilitates the patient's entry and exit from the device, avoids obstruction by the support leg 11 during use, and improves the ease of use of the device.
[0035] 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.
