Horizontal lower limb rehabilitation robot capable of contracting and moving in an ICU ward

Abstract

The invention discloses a horizontal lower limb rehabilitation robot capable of contracting and moving in an ICU ward. The device comprises a human body sign acquisition module, a base module, a lowerlimb exoskeleton, a control module and a rehabilitation evaluation system. Based on modular design, the rehabilitation evaluation and training of different joints of human lower limbs can be realizedaccording to the characteristics of different patients. Design reset command switch to achieve structural shrinkage and deformation, easy to carry and use in small space of intensive care unit. Emergency stop switch, alarm lamp, leg exoskeleton limit block and foot movement limit block are designed to ensure the safe and reliable operation of lower limb rehabilitation training process. Through serial port and network communication, parallel and concurrent processing and database design, the lower limb rehabilitation evaluation process is well managed, and the real-time intelligent evaluationand training of different joint movements of lower limb with multi-mode and multi-parameter is realized. The results can also be visualized highly, which provides data and reference for doctors to make lower limb rehabilitation training program.

Description

technical field [0001] The invention relates to the research field of medical rehabilitation equipment, in particular to a retractable and movable horizontal lower limb rehabilitation robot in an ICU ward, which is used to realize lower limb rehabilitation evaluation and training for patients in intensive care wards. Background technique [0002] Rehabilitation medicine studies have shown that patients with cerebral palsy or lower limb injuries who have not performed lower limb training for a long time will lead to muscle "disuse" atrophy. Therefore, after the postoperative physical signs of patients in the intensive care unit (ICU) are stable, limb rehabilitation should be carried out as soon as possible However, due to the movement disorder of the lower limbs of patients with cerebral palsy or lower limb injuries, they cannot complete limb rehabilitation training independently. Generally, medical staff with certain nursing knowledge are required to help patients complete ex...

Problems solved by technology

[0002] Rehabilitation medicine studies have shown that patients with cerebral palsy or lower limb injuries who have not performed lower limb training for a long time will lead to muscle "disuse" atrophy. Therefore, after the postoperative physical signs of patients in the intensive care unit (ICU) are stable, limb rehabilitation should be carried out as soon as possible However, due to the movement disorder of the lower limbs of patients with cerebral palsy or lower limb injuries, they cannot complete limb rehabilitation training independently. Generally, medical staff with certain nursing knowledge are required to help patients complete exercise training repeatedly. The medical staff in the ward bring a huge labor burden. The more important limitation is that the training time and intensity cannot be accurately controlled, which makes it difficult to achieve the best therapeutic effect in ICU patient training. At the same time, the recovery status of patients cannot be monitored in real time, resulting in repeated training and therapeutic effects. The feedback is not timely, which is not conducive to the effective adjustment of the rehabilitation training plan by medical staff according to the recovery effect of ICU patients

[0003] In addition, the control systems of existing lower limb rehabilitation devices generally have the following problems: 1) The rehabilitation training mode is single, and the rehabilitation needs of patients in each rehabilitation stage cannot be effectively met; 2) The rehabilitation training function for the up and down movement and rotation of the ankle is not available ; 3) The range of motion of the joints is small, and the training effect on the skeletal joints and stomp joints is small, and it is not suitable for the rehabilitation training of the leg joints of ICU patients with cerebral palsy; 4) There is no closed-loop feedback control mechanism, and the lack of adaptive adjustment to the patient's walking state Function; based on the above reasons, there is an urgent need to develop a horizontal lower limb rehabilitation robot in the ICU ward to assist doctors in completing the evaluation and training of lower limb rehabilitation for patients in the ICU ward after surgery
