Device for healing and training
Technical field
The invention belongs to field of medical equipment technology, be specifically related to device for healing and training.
Background technology
Numerous disease can cause patient's walking disorder, such as: nervous system disease, cerebrovascular, leg waist disease etc., with
And contingency is injured is all likely to result in noneffectives's walking function obstacle, have impact on the daily life of patient, after stable disease,
Usually need to carry out Rehabilitation Training in Treating to help patient to recover limb function.By rehabilitation, rehabilitation training, can be effective
Promote the neural restructuring of movement of patient and the compensatory and recovery of muscle strength, skeleton and function of joint, thus part or complete
The limb function of patient is recovered on ground in portion.The more morning that rehabilitation training and treatment start, the final effect recovered is the best, but is opening
In stage beginning, patient tends to wrestling, and is difficult to bear the pain that the body weight of oneself causes, in order to make patient start limbs ahead of time
Functional rehabilitation is taken exercise, and often uses body weight support treadmill training, and it is that the one in extremity motor function rehabilitation training therapy is basic
Method.Assist in, lean on that to turn with walking in water be that to use also be at most most basic loss of weight walking therapies, but their all some limitation
Property.To this end, there is Crinis Carbonisatus to understand mechanical assistance running gear.
On market, existing lower limb walking rehabilitation training loss of weight frame is using motor as power set, including column or framework with
And suspension rod thereon, it being hung with suspension ring assembly under suspension rod, column is provided with suspension ring lifting driver part, and suspension rod inner edge is provided with one
Group fixed pulley, fixed pulley is equipped with steel wire rope, and above-mentioned suspension ring assembly is connected with motor by steel wire rope, and electric machine rotation drives steel
Cord moves along a straight line, and steel wire rope drives suspension ring assembly to move up and down by fixed pulley again, patient's appropriateness is sling, alleviates under patient
The heavy burden of limb, it is ensured that patient carry out walking, balance, safety in the carrying out of the motor capacity rehabilitation training such as stand and training.
During this device uses, still having some shortcomings, due to human body in the process of walking, gravity center of human body is not maintained at a level
On line, but in changing the most up and down, under static state, suspender belt pulling force balances each other with the human body weight being lifted,
In rehabilitation Walking, motor is in and stops rotary state, when gravity center of human body moves up, and the relative relaxation that steel wire rope will become,
Act on the pulling force on human body can reduce;When gravity center of human body moves down, steel wire rope can be tightened up, and its pulling force can tend to increase
Greatly.Ignore the elastic deformation of steel wire rope, human body in walking, center of gravity upwards time steel wire rope there is no weight loss effect, when center of gravity is downward
Can too lift again, destroy the normal gait of human body walking, during so this loss of weight frame can not be well adapted for human body walking
The requirement of gravity center shift, it is impossible to play good loss of weight effect.This kind of weight-losing device still can not apish actual walking
Training, and rehabilitation training person is strapped in narrow range, it is single that training path lacks attitude, relatively big with true walking gap,
The interest lacked in training, easily makes trainer produce and is weary of sense.
Summary of the invention

Demonstrate,prove the safety of operator, trainer and equipment;In the lifting process of suspender, the processor in controller 2 is according to people
Lifting force and lifting speed are controlled by by the actual impression of body engineering and operator, it is achieved smooth starting and stopping.
Microcontroller computer, by the data of pull force calculation instrument and encoder collection are analyzed process, obtains trainer's
Training data, such as speed, distance, actual, loss of weight lifting force etc., and to trainer physical training condition be analyzed judging, right
The rehabilitation state of trainer is analyzed.In the range of normal fluctuating in trainer trains, it is ensured that lifting force is in operation
In the normal range of personnel setting, and keep stable;When displacement transducer detects displacement close to the limit, device can be reported to the police and be carried
Show;When displacement transducer detects displacement break bounds, device is while reporting to the police, and microcontroller computer can be according to the feedback of sensor
Value, controls current of electric, carries out increasing or reduce the corresponding action such as motor lift force, emergency brake and in operator's setting
In the range of make suspender stop motion, it is ensured that the safety of trainer.
In this device busy, if load weight is beyond the normal range set, pull force calculation instrument sends alarm, takes
Action, until hover temporarily, after personnel to be operated or trainer do respective handling, can starter resume work.
Device for healing and training, provides a stable pulling force upwards by suspender for rehabilitation clients, and pulling force size can basis
Needing to set, this pulling force keeps stable during whole training;This device can set its suspender stroke range, imitates people and exists
Dipping and heaving in walking, the horizontal movement velocity of the device that can set, use more flexibly and safety.Such as, walking
In normal fluctuating, then the upwards pulling force that device provides is in dynamic steady state all the time, makes rehabilitation clients alleviate heavy burden, improves row
Smoothness when walking, comfortableness, if rehabilitation training person's accident unstability, then this device can increase lifting power in time and makes trainer
Slow down, until stopping, it is to avoid traumatic injury is damaged.This device can manually actuation means control easily suspender lifting and
Decline, regulate suspender lifting force, set the most spacing of suspender, upper and lower speed limit.It addition, this apparatus structure is simple, low cost, easily
In popularization.
