Description

Technical Field

[0001] The present invention relates to the technical field of bedside limb movement rehabilitation training, and particularly to a bedside limb movement rehabilitation training assistance system. Background Art

[0002] As an important part of the modern clinical medicine system, the core of rehabilitation medicine is to promote the neural function remodeling and motor function reconstruction of patients with functional disorders through scientific and standardized rehabilitation training. The evidence-based medicine evidence system has confirmed that early rehabilitation intervention based on kinesiotherapy can significantly improve the motor function prognosis of hemiplegic patients after stroke, and is the most cost-effective clinical intervention method to reduce the disability rate. The motor function rehabilitation of patients with nerve function injury has obvious time-dependent characteristics. The International Stroke Rehabilitation Guidelines (AHA / ASA) clearly state that early bedside rehabilitation intervention initiated within 24 - 72 hours after onset can increase the efficiency of motor function recovery by 37% - 52% through the mechanism of neural plasticity.

[0003] However, the traditional rehabilitation mode is restricted by the existing technical bottlenecks. That is, most of the existing rehabilitation training programs are designed based on the treatment room scenario. The limited bearing capacity of the physical therapy space leads to the daily reception volume threshold breaking through the clinical safety boundary. At the same time, the existing bedside rehabilitation equipment lacks real-time collection and analysis judgment of the movement training trajectory, and cannot meet the neural remodeling requirements of the movement control closed-loop feedback.

[0004] The above technical defects directly result in only 19% of patients in clinical practice being able to reach the theoretical training intensity threshold. Patients often have insufficient rehabilitation compliance, and the improvement range of the modified Barthel index (MBI) is lower than the ideal value, ultimately leading to an earlier onset of the motor function recovery plateau. More importantly, the degree of motor function deficit is significantly positively correlated with the patient's activities of daily living (ADL). The technical defects of the existing rehabilitation service supply mode not only delay the recovery process of the patient's social participation function, but also lead to an annual increase of 28.6% in the family care cost, forming a continuous social and economic burden. The breakthrough of this technical dilemma urgently requires the emergence of new rehabilitation technology solutions to achieve Pareto improvement in the supply of rehabilitation resources through technological innovation.

When the actions are not in place, the speaker 6 will also broadcast voice to encourage the patient to keep up the good work;

[0067] S4: Through the short-focus projector 8 and the radar sensor 9, rehabilitation training items are set in the system, including limb training items such as shoulder joint activities, elbow joint activities, wrist and hand activities, hip joint activities, knee joint activities, etc. Project the video image onto the screen through the short-focus projector 8, and the patient can complete the corresponding limb movements according to the video. Receive the action parameters of the patient through the radar sensor 9 for data analysis.

[0068] Through the settings of the display screen 502, the speaker 6, the camera 7, the short-focus projector 8 and the radar sensor 9, during use, play the follow-up video through the display screen 502, collect the activity images of the patient during the rehabilitation training through the camera 7, evaluate and analyze through the software in the display screen 502, broadcast voice through the speaker 6 to encourage the patient to keep up the good work, so as to achieve the effect of effective training. Rehabilitation training items are set in the system, including limb training items such as shoulder joint activities, elbow joint activities, wrist and hand activities, hip joint activities, knee joint activities, etc. The patient can complete the corresponding actions according to the video prompts, and receive the action parameters of the patient through the radar sensor 9 for data analysis, so as to achieve the effect of interactive training and further improve the effectiveness of the patient's rehabilitation training.

[0069] The specific solution is as follows: first, the device is moved to the position where it needs to be placed through the universal wheel 2. Through the setting of the universal wheel 2, the universal wheel 2 is rotated and connected to the bottom end of the base plate 1 during use, so as to achieve the effect of convenient movement, thereby improving the utilization rate of the device. Then, the pedal 303 is lightly stepped on to make the support leg 308 contact with the ground for fixation. When the pedal 303 is stepped on, the connecting rod 302 will drive the gear ring 304 to slide downward along the slide groove 3011, and the gear ring 304 will squeeze the movable ring 305 to slide downward along the slide groove 3011. When the second tooth 3051 is disengaged from the slide groove 3011, the movable ring 305 will rotate, and the second tooth 3051 will mesh with the first tooth 3012. The support legs 308 are connected, and the second spring 309 provides downward pressure to the support legs 308 to limit and fix the device to the ground. Through the setting of the fixing mechanism 3, the fixing mechanism 3 is fixedly connected to both sides of the bottom end of the base plate 1 when in use. When the device is moved to the position where it needs to be placed, it can be fixed by lightly stepping on the pedal 303, thereby achieving the effect of convenient and quick operation. Then, the lifting column 401 slides up and down on the fixing column 4, and the heights of the two are adjusted and fixed by tightening the bolts 407, so that the main body 5 is adjusted to a suitable position according to the height and body shape of the patient, and the pull rod 406 is pulled outward, so that the pull rod 406 drives the rack 404 to retract to the positioning component 40 3, that is, the rack 404 is separated from the gear 501, so that the main body 5 can rotate on the connecting seat 402. After the main body 5 rotates to a suitable angle, under the elastic force of the third spring 405, the rack 404 slides in the direction of the gear 501 and meshes with the gear 501 to prevent it from rotating, thereby preventing the main body 5 from rotating during use. After ensuring that the display screen 502 is clamped and fixed in the main body 5 and electrically connected to it, the display screen 502 is turned on for training. Through the settings of the display screen 502, the speaker 6, the camera 7, the short-focus projector 8 and the radar sensor 9, the follow-up training video is played through the display screen 502 during use, and then the patient's active video during the rehabilitation training is collected through the camera 7. The system uses the video to obtain the patient's range of motion, body amplitude and other index parameters, and then evaluates and analyzes them through the AI ​​software in the server host 4. The results are used as voice reminders to urge the patient to complete the movements. If the movements are not in place, the speaker 6 will broadcast voice to encourage them to continue, thereby achieving effective training results.
