Description
Technical field
The utility model relates to a kind of health and fitness facilities, particularly a kind of air bag loss of weight leg training device.
Background technology
Cerebral apoplexy is common disease and the frequently-occurring disease of China, annual new cerebral apoplexy approximately 2,000,000 people in the whole nation, wherein approximately 85% have left over limbs, dyskinesia, walking quality is the important goal of rehabilitation training, and 70% above patient can recover walking ability by starting in early days to get involved ambulation training.But for the patient of the severe limb activity ability such as hemiplegic patient, injury gained in sports patient, in the situation that lower limb support body weight difficulty, it is very difficult carrying out independent ambulation training, the therefore rehabilitation training equipment in the urgent need to training in the situation that body wt is lightened the burden patient.
Reducing to some extent health body weight is a kind of effectively rehabilitation therapy method to reduce the weight-losing (partial weight support, PWS) of lower limb load, to realize, the patient of enabling capabilities deficiency is carried out to early stage various ambulation training.The loss in weight of current clinical use has three kinds, suspension type, water tank type and oblique bed formula.Suspension type is as LOKOMAT recovery exercising robot, patient trains at suspention loss in weight lower limb function, suspention operation is comparatively complicated on the one hand, suspention place contact point pressure is concentrated, comfortableness is inadequate, on the other hand loss of weight amount generally from patient body weight 30%～40%, be suitable for lower limb and can bear a heavy burden and reach 60%～70% above patient; Water tank type is by buoyancy of water, person carries out the Walkings such as complementary or resistance in water to make dyskinesia, when the depth of water is during in human body xiphoid-process level, what lower limb bore is not heavily equivalent to 29% of land body weight, but when water tank type Walking, human body and pond system periphery are used moment of torsion principle, height and the center of gravity of support force change along with water level, and a large amount of viscosity becomes branch fine to change muscular movement pattern under water system basis.Tiltedly bed loss of weight simulates as the polymorphic rehabilitation training assessment system of Italian BTS lower limb rehabilitation robot and Shanghai University of Science and Technology's development is suitable for relying on oblique bed to do to the patient of early stage movement defect disease the training of marking time, tiltedly bed formula loss of weight is difficult to be suitable for more than 70% loss of weight amount, can not carry out real ambulation training simultaneously.
The power-assisting training device (air bag weight-losing device) of differential air pressure (DAP) technology is as a kind of brand-new loss in weight, by air pressure loss in weight assist that human body is stood, walking, running training, avoided suspention loss of weight and the oblique number of drawbacks of bed loss of weight.It utilizes the differential air pressure between lower limb and upper limbs to produce support force vertically upward, and support force is evenly distributed on lower limb, and very approaching with center of gravity, even can be when up to 80% loss of weight amount, and equilibrant force and neutral support force can maintain normal Biological Strength; Utilize support force and air pressure proportionate relationship, can regulate very rapidly loss of weight weight; In the time of user's disequilibrium, the power-assisting training device of differential air pressure (DAP) technology utilizes air bag to fix rigid structure outward can subsidiary level and side force, balance user and prevent from dropping in motion process; Therefore, the power-assisting training device of differential air pressure (DAP) technology is highly suitable for hemiplegic patient, injury gained in sports patient, even running training of the elderly's Walking that exercise intensity is low, to increase patient's lower-limb muscular strength, promote balance, coordination function and walking ability to improve.
