Method for realizing self-adaptive training in dynamic weight reduction device

Abstract

A method for achieving self-adaptive training in a dynamic weight reduction device comprises the following steps that A, a patient is bound through a patient binding device, and a flexible rope body is tightened upwards to provide weight reduction force; and B, when the patient begins to walk, a movement driving mechanism drives a weight reduction table to move in the same direction as the patientat the speed V0, if a deviation sensor at the front part detects a deviation signal of a flexible rope body, a controller controls the weight reduction table to increase the speed, if a deviation sensor at the rear part detects the deviation signal of the flexible rope body, the controller controls the weight reduction table to reduce the speed until a deviation sensor at the front part and a deviation sensor at the rear part cannot detect the deviation signal of the flexible rope body, the moving speed of the weight reduction table is Ve at the moment, and the controller controls the weightreduction table to move in the same direction as the patient at the speed Ve to achieve self-adaptive training with the patient. The training effect is improved.

[0002] For many types of patients with poor body balance, weak lower limbs and damaged brain nerves, weight loss walking training can improve balance ability, exercise corresponding muscle groups, stimulate the central nervous system, etc., and can effectively help patients recover part or all of their movements. In order to shorten the course of rehabilitation, in order to achieve follow-up training during weight loss training for patients, Chinese Patent No. 2019217482033 discloses a dynamic weight loss device for rehabilitation training, which uses an offset sensor to detect the movement of the patient Direction, the motor drives the weight-reducing platform to move in the corresponding direction, so as to realize the follow-up movement. The follow-up method in this dynamic weight-reducing device has made great progress compared with the past self-propelled weight-reducing device, and can be used during training. It saves a lot of medical labor, but the control of this weight reduction device requires the movement of the patient line to trigger the offset sensor, and then the controller can drive the weight reduction table to move. The movement of the weight reduction table has a hysteresis, which causes the following problems: 1. Due to the hysteresis of the movement of the weight loss table, the patient will be subjected to a large pulling force in the opposite direction of the flexible rope before triggering the offset sensor when moving. This pulling force will cause the patient to be strangled very tightly and feel very uncomfortable; the second is After the offset sensor sends out the offset signal, the controller drives the weight-reducing table to move, but the controller does not know the moving speed of the patient. The controller can only judge the moving direction, and then drives the weight-reducing table to move one end distance. If the weight-reducing table moves If the distance is less than the distance from one end of the patient, the patient will still be strangled tightly by the flexible rope body. If the moving distance of the weight-reducing table is greater than the patient’s moving distance, the patient will be strangled tightly by the flexible rope body in the opposite direction. In some cases, the patient still feels uncomfortable, and the body balance of the patient with weight loss training is generally poor. When the tighter situation occurs, the patient's body will have a horizontal traction component, which will cause the patient to lose weight. The body is unstable, or even shakes, leading to particularly bad training feelings such as dizziness. According to the analysis of training practice, the best solution to this problem is to make the weight loss platform and the patient move at the same time and the movement speed of the weight loss platform can be as fast as possible. It is consistent with the patient's moving speed to achieve synchronous movement. In this case, the patient has basically no traction component in the horizontal direction, and the training experience and effect are the best.
