Description

Lower limb training device

Technical Field

The utility model belongs to the technical field of rehabilitation equipment, and specifically relates to a lower limb training device.

Background technique

Lower limb paralysis refers to a disease in which the lower limbs of the body have complete or partial loss of motor function and reduction or disappearance of voluntary movements due to damage to the nervous system and sensory disorders. Rehabilitation training methods for lower limb paralysis include active lower limb training, passive lower limb training, sitting training, standing training, balance training, walking training, etc. After the patient has recovered to a certain extent through treatment, he needs to use a lower limb training device for active lower limb training.

Based on this, the utility model provides a lower limb training device, which can adjust the training intensity according to the patient's physical rehabilitation condition, thereby helping to improve the rehabilitation effect.

As shown in FIGS. 1 and 2 , an embodiment of the present application provides a lower limb training device, including a seat assembly 1 and an adjustment assembly 2. The adjustment assembly 2 includes a first mounting frame 21, a second mounting frame 22, a plurality of elastic members 23 and a force frame 24. The first mounting frame 21 is mounted on the seat assembly 1, the second mounting frame 22 is mounted on an end of the first mounting frame 21 away from the seat assembly 1, the plurality of elastic members 23 are detachably mounted on the second mounting frame 22 and are arranged at intervals, the force frame 24 is mounted on an end of the plurality of elastic members 23 away from the second mounting frame 22, and is configured to be driven to move toward the second mounting frame 22 under the action of an external force, and is configured to be driven to move away from the second mounting frame 22 by the plurality of elastic members 23.

Specifically, when using the device, the patient leans on the seat assembly 1, bends his legs to place his feet on the surface of the force frame 24. By straightening his legs, the patient can drive the force frame 24 to move toward the second mounting frame 22. When the force frame 24 moves toward the second mounting frame 22, the multiple elastic members 23 between the force frame 24 and the second mounting frame 22 are compressed. When the elastic members 23 are compressed, the elastic members 23 apply elastic force to the force frame 24, and the force frame 24 transmits the elastic force to the patient's lower limbs, thereby achieving the purpose of training the patient's lower limbs. When the force frame 24 moves toward the second mounting frame 22, as the distance between the force frame 24 and the second mounting frame 22 shortens, the greater the elastic force on the patient's lower limbs, and the patient can control the stroke of the force frame 24 according to actual conditions.

When the training intensity needs to be reduced, the patient can appropriately reduce the moving range of the force frame 24 on the surface of the first mounting frame 21. Alternatively, the caregiver can appropriately remove some of the elastic members 23 to reduce the number of the elastic members 23. When the training intensity needs to be increased, the patient can appropriately increase the moving range of the force frame 24 on the surface of the first mounting frame 21. Alternatively, the caregiver can appropriately install some of the elastic members 23 to increase the number of the elastic members 23.

The lower limb training device provided in the embodiment of the present application adopts an elastic member 23. The patient can adjust the training intensity by controlling the compression degree of the elastic member 23 through the force frame 24 according to the condition of the lower limbs, which helps to improve the rehabilitation effect. The elastic member 23 is provided in multiple numbers, and the multiple elastic members 23 are all designed to be detachably connected with the second mounting frame 22. In actual application, the nursing staff adjusts the training intensity by controlling the number of elastic members 23 according to the condition of the patient's lower limbs. Compared with only using one elastic member 23 to adjust the training intensity, the training intensity can be adjusted within a larger range, which helps to further improve the rehabilitation effect and also helps to improve the convenience of use.

In one embodiment of the present application, referring to FIG. 1 and FIG. 2 , the second mounting frame 22 is provided with a plurality of first mounting grooves 25, and the plurality of first mounting grooves 25 are respectively arranged in one-to-one correspondence with the plurality of elastic members 23. The elastic member 23 includes a connecting rod 231, a first chuck 232, a second chuck 233 and an elastic structure 234. The connecting rod 231 is inserted into the first mounting groove 25, the first chuck 232 is installed at one end of the connecting rod 231 away from the force-bearing frame 24, and is located on the side of the second mounting frame 22 facing away from the force-bearing frame 24, the second chuck 233 is installed at one end of the connecting rod 231 close to the force-bearing frame 24, and the elastic structure 234 is sleeved on the connecting rod 231, and is located between the second mounting frame 22 and the second chuck 233.

In this way, the connecting rod 231 is adopted, and by passing through the elastic structure 234, when the elastic structure 234 is compressed or extended, the elastic structure 234 can be guided, so that the elastic structure 234 can only be compressed or extended along the extension direction of the connecting rod 231. During the training process, it can prevent the elastic structure 234 from popping out from between the second mounting frame 22 and the force-bearing frame 24 to cause safety hazards, which helps to improve the structural stability of the elastic member 23, facilitates patient training, and helps to improve the convenience of use. The first mounting groove 25 is adopted, and the connecting rod 231 can be guided when the patient drives the connecting rod 231 to move through the force-bearing frame 24, which helps to improve the movement stability of the connecting rod 231, and further helps to improve the movement stability of the elastic structure 234. The first chuck 232 and the second chuck 233 are adopted, and the elastic structure 234 can be prevented from coming off the connecting rod 231 when the elastic member 23 and the second mounting frame 22 are separated, and the elastic structure 234 is prevented from being lost when idle. Furthermore, when the elastic member 23 is mounted on the second mounting frame 22, the first chuck 232 can be used to limit the elastic structure 234 when it rebounds, thereby preventing the connection rod 231 from being separated from the second mounting frame 22, and thus helping to improve the installation stability between the elastic member 23 and the second mounting frame 22. Compared with the direct contact between the connection rod 231 and the force frame 24, the second chuck 233 has a larger contact area with the force frame 24. When the force frame 24 drives the connection rod 231 and the elastic structure 234 to move, the thrust of the patient on the force frame 24 can be stably transmitted to the connection rod 231 and the elastic structure 234, thus facilitating the movement of the connection rod 231 and the elastic structure 234. Furthermore, this helps to improve the stability between the elastic member 23 and the force frame 24.

Optionally, the elastic structure 234 is configured as a spring or a spring.

In one embodiment of the present application, please refer to FIG. 1 and FIG. 2 , the elastic member 23 further includes a linear bearing 235 , which is sleeved on the connecting rod 231 and can be supported on the first chuck 232 under the action of the elastic structure 234 .

Specifically, when using the device, the patient's lower limbs first push the force frame 24, and the force frame 24 moves toward the second mounting frame 22 and transmits the thrust to the second chuck 233. Driven by the force frame 24, the second chuck 233 moves toward the second mounting frame 22 and transmits the thrust to the connecting rod 231 and the elastic structure 234. Driven by the second chuck 233, the connecting rod 231 gradually moves away from the seat assembly 1 relative to the linear axis and the second mounting groove 26, and the elastic structure 234 is compressed. Driven by the connecting rod 231, the first chuck 232 gradually moves away from the second mounting frame 22. After the force frame 24 moves to the target position, the patient gradually reduces the thrust acting on the force frame 24. At this time, the force frame 24, the second chuck 233, the connecting rod 231 and the second chuck 233 stop moving and start moving toward the seat assembly 1, and the elastic structure 234 starts to rebound.

With such a configuration, a linear bearing 235 is used to guide the connecting rod 231 when the connecting rod 231 moves relative to the second mounting frame 22, preventing the connecting rod 231 from rotating relative to the second mounting frame 22 during the movement and causing the connecting rod 231 and the second mounting frame 22 to become stuck, which helps to improve the movement stability of the connecting rod 231 and also helps to improve the convenience of use.

In one embodiment of the present application, referring to FIGS. 1 to 3 , the linear bearing 235 includes a first bearing body 2351 and a second bearing body 2352 . The first bearing body 2351 is sleeved on the connecting rod 231 , and the second bearing body 2352 is connected to one end of the first bearing body 2351 away from the first chuck 232 .

With such a configuration, the first bearing body 2351 and the second bearing body 2352 can both guide the connecting rod 231. The first bearing body 2351 can be connected to the first mounting groove 25 by a snap-on connection, which helps to improve the installation stability between the linear bearing 235 and the second mounting frame 22. The second bearing body 2352 can form a limit with the second mounting frame 22 when the elastic member 23 is installed on the second mounting frame 22 under the action of the elastic structure 234. When guiding the connecting rod 231, the linear bearing 235 and the second mounting frame 22 are relatively stationary, preventing the linear bearing 235 from moving with the connecting rod 231, which is convenient for patient training.

In one embodiment of the present application, please refer to Figures 1 and 2 together. The force frame 24 is further provided with a plurality of second installation grooves 26. The plurality of second installation grooves 26 are respectively arranged in one-to-one correspondence with the plurality of second chucks 233 and are configured to be used for clamping the second chucks 233.

In this way, the second mounting groove 26 is used to limit the second chuck 233 when the elastic member 23 is installed on the second mounting frame 22, preventing the end of the connecting rod 231 away from the second mounting frame 22 from rotating relative to the second mounting frame 22 and the force-bearing frame 24, making it easier for the force-bearing frame 24 to drive the connecting rod 231 to move, which is convenient for patient training and helps to improve the convenience of use.

In one embodiment of the present application, referring to FIGS. 1 and 2 , the lower limb training device further includes a plurality of dampers 3 , and the plurality of dampers 3 are all installed between the second mounting frame 22 and the force-bearing frame 24 .

Such arrangement, using the damper 3, can prevent the elastic structure 234 from driving the force frame 24 to move quickly and cause injury to the patient when the elastic member 23 rebounds or the patient's training intensity exceeds the patient's limit, thereby effectively protecting the patient and helping to improve the safety performance of the device.
