Background technology
At present, because the lower extremity motor function obstacle that the neuropathies such as bone marrow injury, brain trauma, brain paralysis, Parkinson's disease and lower limb muscles, joint injury etc. cause is more and more, endangering greatly human health.Utilizing gait rehabilitation training to carry out Physical rehabilitation treatment to this class patient is a kind of effective method clinically.In gait rehabilitation training, adopt loss of weight support system (Partial Body Weight Support, PBWS) to be conducive to the improvement of the rehabilitation of patient's lower limb disorder and walking ability.Along with the development of technique of medical rehabilitation, loss of weight support system is widely used clinically.
Current existing loss of weight support system has: (1) take Lokomat body weight support treadmill training healing robot as representational passive balancing weight loss of weight support system, highly adjustable in the vertical direction, but when balancing weight moves up and down, can produce inertia force, can not guarantee the constant of loss of weight power.(2) take the passive spring loss of weight support system that Lokomat subsequent product Lokolift is representative, this system adopts a passive spring and active closed-loop control device, has eliminated the inertia impact of balancing weight, maintains constant loss of weight power, but loading range is little, and control difficulty.(3) take application number as 200910048312.9 and 201010515112.2 being representational active loss of weight support system.Application number is that 200910048312.9 patent of invention is a kind of active loss of weight platform based on Electric Machine Control, by motor, drive leading screw to carry out haulage cable, driving suspender belt is the weight that patient (or trainer) sheds self, and patient (or trainer) can be trained under constant loss of weight power.Application number is that 201010515112.2 patent of invention is a kind of pneumatic control weight reduction supporting system, controls the constant tension of lifting rope by controlling pneumatic control.
The loss of weight support system of above-mentioned several forms all adopts suspension type device, make whole trainer must design very tall and bigly, and patient (or trainer) upper limbs is fettered, can not autonomic activities, long-term training patient (or trainer) easily produces sense of discomfort, and also likely falls when training.The patent of invention that application number is 2009100115216.4 provides a kind of thickness according to patient (or trainer) health to regulate horizontal hack lever and longitudinal hack lever that patient's (or trainer) upper limbs is just in time held up and longitudinally on hack lever, by self, has controlled loss of weight power, this method expends the too many muscle power of patient (trainer), weight loss effect is also bad, poor practicability.
Summary of the invention
The object of the present invention is to provide the deficiency of the existing loss of weight supporting way of effective improvement, improve a kind of lumbar support weight reducing device of weight-losing effect.
The object of the present invention is achieved like this:
A kind of lumbar support weight reducing device of the present invention, is characterized in that: comprise main support, motor, leading screw, nut, upright slide rail, horizontal slide rail, slide block, extension spring, lumbar support bar, waist backup plate, back belt, support set piece, slide block comprises the first slide block and the second slide block, upright slide rail is fixed on main support, the first slide block is arranged on upright slide rail, and the first slide block is connected with the support set piece of hollow, and motor is fixed on main support, the output of motor connects leading screw, and leading screw is through support set piece, by bearing spider, be arranged on main support, nut sleeve is on leading screw, thereby being placed in support set piece below drives support set piece to move up and down, horizontal slide rail connects support set piece, and the second slide block is arranged on horizontal slide rail, and lumbar support bar connects support set piece by the second slide block, front apron is installed in horizontal slide rail end, between front apron and lumbar support bar, between lumbar support bar and support set piece, extension spring is all installed, waist backup plate connects lumbar support bar, and back belt is arranged on waist backup plate.
The present invention can also comprise:
1, on described lumbar support bar, post foil gauge.
2, described horizontal slide rail below arranges horizontal slide rail support, and horizontal slide rail support floor is installed on horizontal slide rail support, and horizontal slide rail support floor is connected with support set piece.
Advantage of the present invention is: whole lumbar support loss of weight system has realized closed loop ACTIVE CONTROL, can according to training requirement in various degree, control the constant magnitude of loss of weight power, improves rehabilitation training effect; Control by motor output torque can regulate arbitrarily the size of loss of weight power according to patient's (or trainer) actual rehabilitation training situation, realize different training effects; Pass through lumbar support, liberated people's upper limbs, effectively prevented people's falling in training process, and due to the mechanical constraint of extension spring and lumbar support boom end, make the micro-swinging up and down of patient (or trainer) health in training process, state when meeting normal person and walking, has avoided the sense of discomfort of the long-term training of patient (or trainer); In addition, it is a lot of that the use of lumbar support weight reducing device reduces the height of whole exercise equipment, is more applicable for the uses such as family, hospital.
