Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation training equipment, and in particular to a convenient wearable scar contracture rehabilitation training device based on VR technology. Background Art

[0002] After the skin and soft tissue war wounds and burns are repaired, systematic and precise rehabilitation exercises are needed to combat possible scar hyperplasia and contracture, especially for injuries to joints and active parts. Scar hyperplasia and even contracture will gradually form within half a year to a year after the wound is repaired. In severe cases, joint mobility will be limited, related muscles will atrophy, and even serious deformities will occur. Therefore, precise anti-scar rehabilitation exercises need to be carried out in a timely manner and persist for several months or even longer. In addition, the rehabilitation exercise program needs to be adjusted continuously throughout the process to better combat the gradually appearing scar contracture. VR (virtual reality) technology generates a three-dimensional virtual environment through computers, allowing users to immerse themselves in it with the help of VR glasses. In terms of simulating sports scenes, it can provide users with a highly realistic sports experience, as if they were actually there. In terms of rehabilitation treatment, for some injured patients, VR simulated sports scenes can help them conduct progressive rehabilitation training. For example, by simulating simple limb stretching and joint activity scenes, patients can conduct rehabilitation exercises under the guidance of a virtual environment. At the same time, the software can adjust the difficulty and intensity of the exercise according to the patient's rehabilitation progress.

[0003] In some cases, the wounded are unable to receive rehabilitation treatment in medical institutions at all levels. Rehabilitation exercises after wound healing are often carried out in the wild and in various environments. In the absence of correct and targeted rehabilitation exercise programs, it is very easy for problems such as inadequate rehabilitation exercises at the scar site, inability to accurately evaluate the rehabilitation effect, and inability to adjust the rehabilitation plan in time, which in turn leads to poor results of rehabilitation exercises, severe scar contracture, and affected recovery of limb flexibility.

[0028] Wherein, a driving module 111 and a storage battery 112 are arranged in the driving pack 11. A power display screen 113 and a charging socket 114 are arranged on the side wall of the driving pack 11.

[0029] It should be noted that: This device is used in cooperation with VR virtual reality technology. The wounded wear VR glasses and conduct special training through different training scenarios to improve the pertinence of training items. Under the training in different scenarios, the scar is stretched to avoid joint movement limitation of the wounded caused by scar contracture.

[0030] It should be noted that: The driving module 111 can drive the power assist mechanism 210 to stretch the leg according to the movement scenario, so as to push the leg joint to move and provide power assistance for the leg.

[0031] Among them, somatosensory positioning sensors 4 are installed on one side of the base 21, the connection between the first rod body 23 and the second rod body 24, the connection between the second rod body 24 and the foot rod body 25, and the connection between the upper arm rod body 35 and the lower arm rod body 36.

[0032] It should be noted that the body sensing positioning sensor 4 is used to record the movement trajectory during the rehabilitation training process, regularly provide feedback to medical institutions and conduct phased rehabilitation effect evaluation, and adjust the frequency, angle and intensity of rehabilitation exercises according to the evaluation results. Example

[0033] like Figure 1-Figure 9 As shown, in this embodiment, the injured person stands on the pedal 27 and presses the heel against the heel limiter 29, and then fixes the ankle with the ankle strap 28. Subsequently, the drive pack 11 is fitted to the back waist, and the hip fixing block 13 is fitted to the waist, and then the inner connecting belt 14 and the outer connecting belt 15 are connected by Velcro, so as to fix the waist binding mechanism 1 to the waist.

[0034] Adjust the limit block 235 to slide in the through groove 233 so that the connection between the first rod body 23 and the second rod body 24 is located at the knee position, insert the pin 239 into the socket 237 and a corresponding limit hole 238, fix the upper rod body 231 and the lower rod body 232 to adapt to the leg size of the injured person, and then put the leg strap 26 on the injured person's leg to fix the lower limb assembly 2 to the injured person's leg.

[0035] The shoulder strap 31 is pressed against the back of the injured person, and the injured person passes both arms through the shoulder loop 32, the fixing ring 34, the fixing strap 38 and the elastic loop 313, so that the elastic loop 313 is at the wrist, and the elastic loop 313 shrinks and deforms to fix a pair of forearm rods 36 to the wrist, and then pulls one end of the fixing strap 38 to tighten the fixing strap 38 to fit the arm, thereby fixing a pair of upper arm rods 35 to the arm, and then the upper limb assembly 3 is worn and fixed to the upper limb.

[0036] From the above, it can be seen that the device is easy to wear, can be adapted to patients of different body shapes, has high adaptability, improves product utilization, saves production costs, and the patient can wear the device while wearing complete clothing, which can provide a buffer between the device and the patient's skin to prevent the device from directly abrading the skin and causing damage.

[0037] The injured wear VR glasses and use VR virtual reality technology to simulate rehabilitation training scenarios, so that targeted training can be carried out. The body positioning sensors 4 installed at each joint can provide feedback on the movement trajectory of the limbs, thereby judging the training effect.

[0038] VR simulated rehabilitation exercise scenes and the somatosensory positioning sensor 4 provide timely feedback on the action targets, guiding daily rehabilitation exercises. It can also increase the fun of simulating the actual work and life needs according to the rehabilitation progress, and assist in completing specific rehabilitation actions and overall plans.

[0039] During the training process, the power-assisting mechanism 210 of the lower limb component 2 can stretch the knee. When performing posture training such as knee bending, the driving module 111 starts the driving motor 2106 to rotate gear 2 2107. The rotation of gear 2 2107 in turn drives the gear 1 2105 meshing with it to rotate. While gear 1 2105 drives gear column 1 2103 to rotate, it also drives gear column 2 2104 meshing with it to rotate, so that the C-shaped rack 2102 meshing with gear column 1 2103 and gear column 2 2104 rotates with the connection between the first rod body 23 and the second rod body 24 as the center of the circle, thereby driving the second rod body 24 to rotate synchronously through the rotating shaft 2101, thereby driving the leg to perform posture training such as knee bending.

[0040] From the above, it can be seen that: since there are more muscle tissues in the legs, the device can perform knee bending training through the power-assisting mechanism 210, thereby stretching the legs, which can increase the flexibility of scar tissue, reduce its hardness and tightness, and help restore the normal range of motion of the legs.

[0041] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
