Description
Technical field
The invention belongs to the rehabilitation medicine equipment technical field, particularly relate to a kind of pneumatic control loss of weight support system.
Background technology
At present, a lot of countries have begun to enter aging society, and disease, disaster and other factors have formed the bigger disabled person colony of quantity, and they need a large amount of relief and medical vehicle caring service.Because backbone or brain damage cause the patient of the handicapped or crural paralysis of lower limb at China's One's name is legion, a kind of method preferably of this class patient being carried out the physics rehabilitation is to carry out the gait rehabilitation training.In the gait rehabilitation training, adopt loss of weight support system (Partial Body Weight Support, PBWS proposed in 1986) can alleviate patient's burden, reach more effective rehabilitation efficacy.Enter 21 century, along with the development of rehabilitation technology, the loss of weight support system has obtained application clinically more and more widely.The form that it adds suspender belt from early stage single fixed frame is developed to air-pressure type loss of weight system now, makes loss of weight support treatment variation more.Existing a large amount of bibliographical information PBWS all has great advantage than traditional treatment recovering walking ability, correct gait, improve balance, alleviate muscle cramp and reduce aspects such as cardiopulmonary load, reduce therapist's working strength simultaneously, improved the security of treatment.Computer technology is applied to the loss of weight support system, can writes down the treatment data in the training process in detail objectively, analyze and estimate the rehabilitation training effect for the physiatrician.
At present, existing loss of weight support system has: 1. static loss of weight support system, the major defect of this system be, because rope is long fixing object motion the time, so the motion about barycenter not have during object motion, tension variation is big; 2. passive equilibrium piece loss of weight support system, the major advantage of this system is, move up and down when can make object motion, the major defect of this system is, owing to have inertia force object motion the time, makes the tension value change at random of rope, and because the weight of balance weight disperses, so tension value disperses, can not adjust to arbitrary value, and be several steady state values; 3. passive spring loss of weight support system, the major advantage of this system be, inertia force can be ignored, and the major defect of this system is because usefulness is spring, so loading range is little, and the object center of gravity when moving up and down the system tension value change.
Summary of the invention
Deficiency at existing loss of weight support system exists the invention provides a kind of pneumatic control loss of weight support system; This system is the closed loop ACTIVE CONTROL, the tension value of loss of weight support system can be controlled within the specific limits, reaches the purpose of permanent tension force control.
To achieve these goals, the present invention adopts following technical scheme, a kind of pneumatic control loss of weight support system, comprise frame with base, be characterized in that frame is provided with first fixed pulley and second fixed pulley, the base of frame is provided with cylinder, and the piston rod of cylinder is provided with movable pulley, on the base of cylinder both sides, be respectively arranged with the 3rd fixed pulley and the 4th fixed pulley, be provided with capstan winch in the side of the 4th fixed pulley; The braces that is arranged on the frame below is connected with capstan winch through power sensor, first fixed pulley, second fixed pulley, the 3rd fixed pulley, movable pulley, the 4th fixed pulley successively by connection cord; On described cylinder position sensor is installed, described cylinder is connected with pneumatic control valve with pressure sensor respectively, and described pneumatic control valve is connected with air pump station; Described power sensor, position sensor, pressure sensor, pneumatic control valve and capstan winch are connected with computer respectively.
Described pneumatic control loss of weight support system also can be provided with monitoring arrangement, and described monitoring arrangement is connected with described computer; Be used for real time monitoring motion of objects situation.
Beneficial effect of the present invention:
1, loss of weight support system of the present invention is the closed loop ACTIVE CONTROL, the tension value of loss of weight support system can be controlled within the specific limits, reaches the purpose of permanent tension force control, the control accuracy height;
2, loss of weight support system of the present invention can realize that the continually varying loss of weight supports tension force, is applicable to the object of different weight;
3, loss of weight support system of the present invention is safe and reliable, easy accessibility, but the omnibearing protection user's is safe in utilization.
