Description

A medical rehabilitation balance exercise robot

Technical field

The invention relates to medical device technology, and in particular to a medical rehabilitation balance exercise robot.

Background technique

With the deepening of the aging process in our country, the health problems of the lower limbs caused by aging are becoming more and more prominent. The flexibility of the lower limbs in the elderly continues to decline due to the decline of physiological functions. In addition, the number of patients with limb movement disorders caused by various diseases such as spinal cord injury and stroke is also significantly increasing. Therefore, people are paying more and more attention to the field of lower limb rehabilitation. . The pelvis is the hub connecting the trunk and lower limbs. Studies have shown that exercising patients' pelvic motion control has a significant effect on the recovery of patients' lower limb motion abilities. Improving patients' ability to control pelvic motion through exercise has become the focus of research on lower limb rehabilitation robots; as of the end of 2021, nationwide The elderly population aged 60 and above is 260 million, accounting for 18.9% of the total population. It is estimated that in 2025, the number of 60-year-olds in my country will reach 300 million, accounting for 21% of the total population, and the number of people over 65 years old will also reach 13.7%. Falls are the number one cause of injury and death for the elderly over 65 years old in my country. Timely diagnosis, treatment and rehabilitation of elderly people after falls, especially the standardization, accuracy and individualization of rehabilitation training after falls, are crucial. However, the main cause of falls in the elderly is imbalance (reduced gait stability and balance impairment). The original purpose of making this device is to provide balance rehabilitation exercises for the elderly after hip fracture surgery. It is suitable for people who have gotten out of bed and can walk and need balance training.

The Chinese invention patent with publication number CN115154214A discloses a lower limb walking auxiliary exoskeleton robot. The lower limb walking auxiliary exoskeleton robot inputs the patient's leg length data on the touch screen intelligent controller. Control the electric lifting rod to lift and adjust so that the curved guardrail is located at the patient's waist. The patient enters the inside of the curved guardrail, binds his legs side by side to the walking leggings on both sides of the bottom of the curved guardrail, and connects the first connecting sling. After passing the end of the first connecting sling and the second connecting sling under the patient's crotch, thread the ends of the first connecting sling and the second connecting sling respectively into the spiral rod seats on the side walls at the top of the walking leggings on both sides of the arc-shaped guardrail. , so that the first limiting ball at its end is clamped on the top of the spiral rod seat, the woven mesh pad between the side walls of the first connecting sling and the second connecting sling supports the patient's buttocks, and connects the first connecting sling and the second connecting sling. After the auxiliary tying rope on the outside of the second connecting sling crosses with the second limiting ball, the spiral rod seats on both sides of the waist pad are buckled according to the above method. The auxiliary tying rope cooperates with the waist pad to bind the patient's waist. Walking exercise is supported by curved guardrails, electric lifting rods and moving wheels. After the patient is tired from exercise, he can immediately bend his lower limbs and sit on the woven mesh cushion. The woven mesh cushion can carry the patient directly to sit and rest, which is easy to use.

At present, there is no clinical equipment related to balance rehabilitation exercises for the elderly after hip fracture surgery. Most of the balance training equipment on the market are suitable for children and young adults. The elderly are prone to falls and fragility fractures. Elderly patients with hip prosthesis replacement often cannot adduct or externally rotate their lower limbs due to surgery, and most balance training devices are limited.
