Abstract

The invention provides a device for assisting a heart failure patient in exercise training by means of electrodynamic force. The device consists of a motor, a worm wheel and a worm, swing arms, push-and-pull rods, lower leg supports, upper leg supports and the like, wherein, the motor can push limbs of the patient to passively move; a sliding rail is arranged between a backing plate and a bed plate so that the backing plate can freely slide so as to prevent joint muscle injury caused by overlarge pushing force; and the patient can also actively take exercises. Therefore, the device plays a good role in assisting the heart failure patient in exercise training.

Description

Patients with heart failure rehabilitation training machine

Technical field

The invention belongs to rehabilitation training equipment field.

Background technology

Scientific research in recent years shows that training can be corrected heart failure (heart failure) patient's circulation congestion state, can improve the endothelial function of whole body blood vessel, reduces complication (as lower limb phlebothrombosis, pulmonary infarction), can improve patient's cardiac function.The rehabilitation of patients with heart failure has become the important content that the cardiac treats guide.But, patients with heart failure is carried out training intensity and is difficult to grasp, be easy to occur fatigue and dyspnea symptom, how can bring into play that training can avoid again occurring overworked and increasing the weight of symptoms of heart failure to the therapeutical effect of heart failure is problem demanding prompt solution, for this reason, the present invention has designed a kind of electrical equipment, can help the patient to carry out passive exercise, also can make the patient initiatively participate in carrying out the resistance exercise of electronic auxiliary active exercise, active exercise and antagonism motor machine power, can address this problem preferably.

Summary of the invention

The purpose of this design is to make a kind of equipment, carries out passive exercise, electronic auxiliary active exercise, active exercise and resists electric-powered resistance exercise by electric-powered help patient.

The technical scheme that adopts: structure of the present invention as shown in drawings: in the accompanying drawing 1: (1) is variable-speed motor; (2) be the worm and gear structure; (3) be the swingle that links to each other with worm and gear; (4) for worm screw with get rid of arm and be connected twisted buckle; (5) for getting rid of arm; (6) for get rid of that arm is connected with the shank support have the elastic telescopic function, to the push-pull bar that pushes away, pulling force can play cushioning effect, be provided with the thrust display, can show push away, the size and the positive and negative indication of pulling force, when doing the moving motion of thrust for just, when doing the pulling force motion for bearing; (7) for holding up the support of shank; (8) be the support that adheres to mutually with thigh, length is adjustable; (9) be the fixing Elastic bandage of knee joint and ankle joint of binding; (10) be mobile backing plate; (11) be bed board; (12) be positive and negative thrust display; (13) be handle, each one of mobile backing plate both sides correspondence position has sliding rail between backing plate and the bed board, and right hand handle top has switch lock, presses can lock track and do not make its slip, by opening lock it can be free to slide again; In the accompanying drawing 2: (14) are bed cradle; (15) for hanging the grid of fixed pulley; (16) be fixed pulley.

Motor is with suitable rotational speed, then can by worm screw with get rid of the support that arm drives with patient's shank is connected with thigh and move back and forth.Get rid of being connected twisted buckle and can being fixed in positive and negative (180 °) both direction between arm (5) and the swingle (3), the two lower limb of patient can be done synchronous flexion and extension, mutually opposite motion to pedal in the time of also can doing.Push-pull bar has the elasticity Collapsible structure, not only to mechanical movement push away, pulling force plays cushioning effect, can also stretching by it, positive and negative thrust display demonstration push away, the size (quite each the 50kg pressure of each 5cm of can stretching under normal conditions, contract) of pulling force apart from driving, and the patient can check the degree of patient's muscle contraction strength size and Myodynamia recovery when the motion of doing passive exercise, auxiliary active exercise, active exercise and resisting electronic thrust.Between bed board (11) and backing plate (10), the longitudinal sliding motion track is arranged, can regulate the front and back position of backing plate, the hand-held fixed bar switch lock (13) in right side is in the state of untiing can be made backing plate be free to slide and avoid mechanical thrust improper and cause the articular muscle damage, can regulate the appropriate location of health, the locking pads Board position can be handed handle with the fixing position of health, so that two upper and lower limb can cooperate training then; The patient can also help limbs to carry out the activity exercise by the sandbag of fixed pulley (16) suspension constant weight.

Beneficial effect

Utilize this equipment can make heart failure patient carry out passive hip in the wrong go down on one's knees activity and to pedal the motion, also can allow the patient initiatively participate in carrying out the resistant exercise of electronic auxiliary active exercise, active exercise and antagonism motor machine power, existing safety guarantee can be avoided because of the electric-powered excessive articular muscle damage that causes, can also help the patient to perform physical exercise by the sandbag of suspended constant weight, can play the effect that auxiliary preferably patients with heart failure is carried out training.

Description of drawings

Accompanying drawing is a structural representation.In the accompanying drawing 1: (1) is variable-speed motor; (2) be the worm and gear structure; (3) be the swingle that links to each other with worm and gear; (4) for worm screw with get rid of arm and be connected twisted buckle; (5) for getting rid of arm; (6) for getting rid of the push-pull bar that arm is connected with the shank support with the scalable function of elasticity; (7) for holding up the support of shank; (8) be the support that adheres to mutually with thigh, length is adjustable; (9) for being twined, knee joint and ankle joint position and support tie up fixed binder; (10) be mobile backing plate; (11) be bed board; (12) be positive and negative thrust display; (13) for having the handle of switch lock; In the accompanying drawing 2: (14) are bed cradle; (15) for hanging the grid of fixed pulley; (16) be fixed pulley.

Embodiment

The patient is lain on the back on backing plate (10), shank is placed on above the support (7), with Elastic bandage (9) be fastened knee joint and ankle joint position, open the switch lock on the handle (13), make between backing plate (10) and the bed board (11) and can be free to slide, start motor (support rises and falls and moves 10-30 time/minute) with suitable rotating speed, beginning drives passive the doing of patient earlier and bends the hip kneebend.If the patient is sensation movable amplitude and location-appropriate, then the right hand is held handle (13) locking switch lock, progressively adjust motor speed,, progressively do passive exercise, electronic auxiliary active exercise, active exercise and resist electric-powered resistant exercise with backsight patient muscle power situation.These four kinds motions firmly size can show on positive and negative thrust display (12).The patient can also utilize pulley (16) to hang sandbag and perform physical exercise.

Claims

1. device that helps patients with heart failure to carry out training, it is characterized by: motor gets rid of arm by the worm and gear drive and moves in a circle, get rid of arm and drive little leg support and the thigh support frame that the push-pull bar with elasticity Collapsible structure promotes the patient again and move reciprocatingly, thus the help patient does that passive hip in the wrong is gone down on one's knees etc. motion.
