Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation medical equipment, and in particular to an intelligent rehabilitation double-track treadmill system. Background Art

[0002] At present, treadmills have become a common equipment for physical training not only in homes and gyms, but also in the field of rehabilitation training. For example, they are used for gait training of patients with sequelae of stroke, and for correction and training of gait abnormalities caused by leg muscle damage, etc., which have good therapeutic effects.

[0003] At present, most treadmills have only a single track and can only provide the same running speed; however, it is difficult to provide targeted training for some patients with bilateral imbalance; although, in response to this demand, many manufacturers have developed dual-track treadmills, although the newly developed dual-track treadmills have dual tracks and support different speeds of rotation, it is difficult to synchronize the speeds of the dual tracks, resulting in poor training results for patients with bilateral imbalance in the later stage; therefore, designing a treadmill that can support different speeds and synchronize to better adapt to patients using training equipment is an urgent problem to be solved.

[0004] During rehabilitation training, rehabilitation therapists or doctors usually set up training plans, and rehabilitation therapists and nurses monitor patient training. Although there is communication during training, it is still difficult to quantitatively evaluate the patient's training intensity. Currently, there are few monitoring cardiopulmonary parameters in the market to adjust exercise intensity to obtain the best training effect. How to organically combine treadmill training with cardiopulmonary monitoring to improve training effects is also a research focus of rehabilitation training. At the same time, the pressure distribution of the foot during running can intuitively reflect the gait condition, so foot pressure monitoring is also helpful in formulating reasonable training plans to obtain the best rehabilitation effect.

[0005] This patent aims to provide an efficient, safe and intelligent dual-track rehabilitation training treadmill system. The system monitors the cardiopulmonary system by collecting ECG and pulse information in real time; it can provide bilateral asymmetric gait training and bilateral synchronous training through dual tracks; at the same time, a pressure sensor is placed under the running belt to observe gait information in real time and adaptively adjust the personalized training plan to obtain the best rehabilitation effect.
