Description

Two-stage bed body, multi-angle regulate, upper and lower extremities coorinated training healing robot
Technical field:
The present invention relates to a kind of two-stage bed body, multi-angle regulates, upper and lower extremities coorinated training healing robot, belongs to rehabilitation medical instrument field.
Background technology:
Recovery exercising robot is a kind of novel medical rehabilitation training aids, is the product that Robotics and medical science of recovery therapy combine, and helps limbs to have the patient of functional disorder to complete the passive exercise for coordination of limbs master, reaches the object of limb rehabilitating.But healing robot is mainly divided into several classes such as single-degree-of-freedom, exoskeleton-type, suspension type and sitting and lying formula at present, at present there is complicated operation, poor stability, patient in rehabilitation training, occur that health energy imbalance or unstable oscillation, patient are too passive in rehabilitation training in this few class, be unfavorable for giving play to a subjective initiative, the problems such as rehabilitation training scope is less, training track is single.And along with the growth of China's elderly population, and variously cause the patient of physical disabilities to increase because of unexpected injury, it is wide to develop a adaptation population, and towards family, can meet patient personalized rehabilitation training demand, be the key of recovery exercising robot research instantly.
The develop rapidly of medical science of recovery therapy theory in recent years, the rehabilitation theory of various related activities training occurs, like the mushrooms after rain under the drive of these theories.Limbs image training robot gradually becomes a study hotspot in medical rehabilitation research, as:
(1) Wearable healing robot developed rapidly in recent years, and a lot of mechanism and university all carried out further investigation to this, and some has entered actual business utilization, but Wearable healing robot operating process is comparatively complicated.Need the personnel of specialty to accompany and attend on side, walk abreast and carry out Operating Guideline, consume a large amount of manpowers.In addition, the price of dressing robot is all high, needs operator to have higher professional ability, is therefore difficult to enter general mini clinic, home for destitute, family.
(2) suspension type robot, is sling human body by weight reducing device, alleviating patient's load that leg bears when training, allowing it carry out body weight support treadmill training.But it has a fatal shortcoming to be exactly owing to being be suspended in by human body in the air, center of gravity is too high, patient is subject to the situation of external force unexpected or well do not adjust the attitude of oneself, there will be waving and rotating of health, not only bad for exercise rehabilitation training, also may touch the miscellaneous part of healing robot, even bring beyond thought injury.This type of recovery exercising robot needs special personnel nurse always and operate simultaneously, is not suitable for average family and the use of little home for destitute.
(3) although sitting and lying formula recovery exercising robot can alleviate the impact of gravity to a certain extent, the training track of current most of sitting and lying formula recovery training appliance for recovery is fixed, and is difficult to set different training track, amplitude according to the personal feature of different patient.
By analyzing known to existing various rehabilitation machines above; Design a good healing robot and need that there is following feature: be 1, moderate, be applicable to little rehabilitation institution and home for destitute, or even individual family.2, the operation of healing robot is comparatively simple, and the healthcare givers without the need to specialty carries out guidance and accompanies and attends to.3, be applicable to the personal needs of different crowd and different convalescence patient, and will human cinology be met.
