Description

Technical Field

[0001] The present invention relates to the field of medical rehabilitation robots, and in particular to an integrated intelligent composite rehabilitation bed. Background Art

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by chronic bronchitis and / or emphysema with airflow obstruction, which can further develop into cor pulmonale and respiratory failure. It has high disability and mortality rates. COPD patients are prone to muscle atrophy, which causes varying degrees of damage to respiratory function. In response to this situation, Professor Zheng Zeguang of the State Key Laboratory of Respiratory Diseases of Guangzhou Medical University has developed a set of Zheng's rehabilitation exercises suitable for critically ill COPD patients. Specific exercises include stretching sit-ups on the bed, bridge exercises, aerial cycling, and standing up and sitting down in a wheelchair. There are many nursing beds on the current market, but few professional rehabilitation training devices. There is a lack of an integrated intelligent composite rehabilitation bed for COPD patients that is specifically designed for Zheng's rehabilitation exercises.

It includes a push handle mechanism, a bed structure, a bed board structure, a linkage mechanism, a bed board support mechanism, a forward push steering mechanism, and a roller base mechanism. By using an electric push cylinder push rod, the back support, waist support, and leg support are driven independently or jointly to achieve back lifting and sitting postures. It can also realize the function of automatically transforming one side of the bed into a chair and rotating 90 degrees at the same time. However, it has certain shortcomings, mainly reflected in that the nursing bed is mainly for daily care of patients, has no auxiliary rehabilitation training function, no intelligent detection function, and cannot realize active rehabilitation training for patients. The patent with publication number CN216877053U discloses a lower limb rehabilitation robot ankle joint control system. It includes a motor, a first roller and a plurality of second rollers, and a traction rope, wherein the first roller is fixed to the output shaft of the motor, one end of the traction rope is fixed to the first roller, and the other end is sequentially wound around the plurality of second rollers and passed through the rotating part and fixed to the first roller, the motor is connected to the fixed part, a detection unit is provided on the side wall of the fixed part, the detection unit is connected to a control unit, the detection unit is used to detect the relative position of the rotating part and the fixed part, and the control unit controls the power-on state of the motor according to the detection signal of the detection unit. It has certain shortcomings, mainly reflected in that the rehabilitation robot is specifically for lower limb rehabilitation training, and the versatility and utilization rate are not high.
