Background technology
Show according to clinical experience: laid-up patient, bed the ligament atrophy promptly occurred more than 4 days, the phenomenon that the muscle tendon is degenerated, this has had a strong impact on orthobiosis and work behind the patients ' recovery.And, be faced with the situation that knee joint does not possess normal function too such as the patient of patellar fracture.Patient that nervus centralis is impaired and cerebral thrombus patient, its lower part of the body is stretched limb tension force and is increased, ligament fibersization, the bone calcium loss is serious, the knee joint osteoporosis.And this situation is that operation institute is incurable, can only rely on rehabilitation maneuver to treat.Medical profession extensively adopts the passive type rehabilitation therapy now, this therapy is intended to be certain subtended angle swing by apparatus drive patient's thigh and shank, because the patient makes muscle group be in a kind of abnormal state because of bed or other reasons, so thigh and shank can not be swung in normal subtended angle scope, but present an abnormal state of affairs, promptly can't reach the degree of bending and stretching that healthy people can reach.Bend and stretch in the process at patient's shank, patient's lumbosacral region can be lifted.Human body is a globality mechanism, and the athletic meeting of lower limb touches the motion of whole human body, tempers patient's whole-body muscle tissue thereby reach, and the purpose of ligament tissue is convenient to patients ' recovery.The special feature of this therapy is the pilot process that bends and stretches at thigh and calf, the curved limit process of bending, and three positions of extension limit process realize that altofrequency knocks or vibrate, and go round and begin again, thereby realize therapeutic process.This therapy curative effect is reliable, but realize to exist by manpower a lot of not enough, as the periodicity of gyration, the accuracy of maximum and minimum subtended angle, the stability of vibration frequency all can not well be guaranteed, thereby curative effect is affected.In addition, the manpower therapy expends a large amount of manpower and materials, has all limited the promotion and application of this therapy.
Summary of the invention
The purpose of this utility model provides a kind of ligament of limbs atrophy, muscle tendon of degeneration of making and obtains the therapeutic equipments of rehabilitation, it has overcome the defective that the stability of accuracy, the vibration frequency of the periodicity of the existing gyration of available man-power therapy, maximum and minimum subtended angle all can not well be guaranteed, realize intellectuality, electromechanical integration.
The technical scheme that its key issue that solves this utility model adopts is:
1. used motor 2 16 to drive cam mechanisms and realized vibrations, replaced in the past that nurse's manpower knocks, thereby guaranteed the stability of vibration frequency at ad-hoc location.
2. used motor one 23 drive rod members 3, rod member 4, thereby the drive thigh and calf is certain subtended angle motion, has replaced manpower work in the past, has guaranteed the periodicity of gyration, and maximum and minimum subtended angle is accurate.
3. adopt the run location of travel switch 21 (about each, i.e. stroke switch 1 and travel switch 2) and optocoupler 22 monitoring forks 3, thereby when rod member arrives ad-hoc location, the switching of realization function.
4. in the selection of power supply, adopt civilian 220V alternating current, be convenient to its universalness.
5. on outward appearance was selected, body had adopted white appearance, and special part adopts black, to make things convenient for the defective patient of vision.
Owing to adopted above-mentioned measure, this utility model is treated than traditional manpower, guaranteed the periodicity of gyration, maximum and the accuracy of minimum subtended angle and the stability of vibration frequency better.This provides a kind of valid approach for the knee joint rehabilitation, and helps extensive popularizing.
