Description

TECHNICAL FIELD

[0001] The utility model relates to two legs recovery training device technical field, especially in neurology two legs linkage multifunctional recovery training device. BACKGROUND

[0002] In the field of neurology two legs rehabilitation treatment, it is crucial to help patients recover leg function. From a physiological perspective, the movement of both legs can stimulate the nervous system and promote the recovery of nerve conduction function. Through regular two legs training, the strength and endurance of leg muscles can be enhanced, and blood circulation can be improved. Adequate nutrition and oxygen are provided for nerve tissue, which helps the repair and regeneration of damaged nerve cells and improves the plasticity of nerves. From the perspective of rehabilitation mechanism, two legs training can help patients recover motor function and balance ability. For patients with nervous system diseases such as stroke and spinal cord injury, lower limb movement disorders often occur. Through targeted two legs training, the movement control ability of the legs can be gradually recovered, and the walking ability and daily life self-care ability of the patients can be improved. At the same time, during the training process, the patients need to constantly adjust their body balance, which also helps stimulate the nervous system to adjust and recover the balance function. In summary, in neurology, training both legs plays an important auxiliary role in the recovery of patients.

[0003] However, due to the traditional two legs training recovery method, the patient needs to temporarily get off the wheelchair and sit on the seat in the specific training device, and then use the relatively single training equipment for rehabilitation training. For example, the common two legs linkage rehabilitation training instrument. When using this kind of equipment, the patient often needs to go through a relatively complex process, such as transferring from the wheelchair to the training equipment seat. This process may require the assistance of others, not only consuming time and energy, but also possibly causing discomfort to the patient. Therefore, this paper proposes a neurology two legs linkage multifunctional recovery training device that does not require the patient to get off the wheelchair for two legs training.

[0024] As shown in Figures 1-4 , a neurological leg linkage multifunctional recovery training device, comprising a base plate 1, one side of the base plate 1 is provided with a four limbs linkage transmission mechanism 2, the four limbs linkage transmission mechanism 2 is mainly composed of a rocker 211, two slide rods 212, four guide rods 209, four guide cylinders 207, two connecting frames 205 and two pedals 208, the four guide cylinders 207 are stably fixed and installed on the top of the base plate 1, and the above-mentioned guide cylinders 207 are in an inclined state, providing stable support for the two slide rods 212;

[0025] Reference Figure 1 and Figure 3 The middle part of the rocker plate 211 is rotatably mounted above the base plate 1, similar to a seesaw in the prior art. When one end of the rocker plate 211 is forced to rotate, the other end of the rocker plate 211 will rotate in the opposite direction synchronously with the middle part as the axis. The first ends of the two sliding rods 212 are symmetrically and slidingly installed at the two ends of the rocker plate 211, respectively. The two sliding rods 212 are mainly used for compensating the lateral length of the rocker plate 211 through extension and contraction. This design makes the sliding rods 212 more flexible during movement. The ends of the two sliding rods 212 are hingedly connected to the two connecting frames 205, respectively. The two connecting frames 205 are fixedly installed at the ends of the four guide rods 209, respectively.
