Description

Weight-reducing walking training device

Technical Field

The utility model belongs to medical equipment, relates to rehabilitation equipment, and particularly relates to a weight-reducing walking training device for patients with lower limb paralysis or walking difficulty.

Background

Walking training is an important link for hemiplegic patients to recover walking ability. In addition, patients who have difficulty walking due to accidents such as car accidents need scientific walking training on the premise of surgery and medication.

The weight-reducing walking training is a training method for recovering lower limb strength and walking ability, and reduces part or all of the weight of a patient in a hanging manner, so that the patient can keep balance and perform gait training, and the patient with insufficient lower limb strength can recover walking ability step by step. There are two general types of weight loss gait training products available: firstly, a constant tension is provided for a patient through a balancing weight and a suspension device to achieve the purpose of weight reduction, and because the load of a user during walking training is dynamically changed, the weight reduction mode of the constant tension cannot always dynamically reduce the load of the user, and in the process of accelerating the body of the user upwards and downwards, the inertia of the balancing weight can generate a large force, so that the supporting force of legs of a participant is increased; and there is a problem in that the operation of adjusting the balance weight is complicated. The second is to add the dynamic weight-reducing products of the spring mechanism, although the leg load of the user during walking training can be dynamically adjusted by adding the springs, so that the effect of dynamic weight reduction is realized; however, because the tension of the spring is changed in the stretching process, the weight reduction value is correspondingly changed, so that the weight reduction effect is unstable, and the training effect is poor.

Therefore, it is necessary to provide a novel weight-reducing walking training device to solve the problems of unstable weight-reducing effect and poor training effect caused by the floating weight-reducing value due to the change of the tension of the spring in the stretching process of the existing dynamic weight-reducing product.
