Abstract
Description
Technical Field
[0001] The utility model relates to a medical rehabilitation training device equipped with an IGBT driving device, belonging to the technical field of medical rehabilitation training devices. Background Art
[0002] There are two technical routes for existing IGBT drivers: analog and digital. IGBT analog drivers have realized the chipization of core circuits, but their driving parameters and protection settings are mostly fixed or can only be adjusted by changing peripheral circuits. In addition, the communication protocol between the analog driver and the upper controller is relatively fixed and cannot be compatible with multiple application scenarios, which greatly limits the scope of application of analog drivers. The core technology has also been monopolized by foreign countries for a long time. The control and protection capabilities of IGBT digital drivers are faster, more accurate, and more flexible, and their reconfigurable functions have greatly broadened the performance of IGBT digital drivers. However, current IGBT digital drivers are designed with discrete devices, and there is no dedicated IGBT digital driver chip. Therefore, compared with IGBT analog drivers, IGBT digital drivers have obvious shortcomings in terms of large size and high cost. The chipization of IGBT digital drivers is a key path to reduce cost and volume and improve reliability. It is an inevitable trend for the new generation of IGBT drivers. Applying IGBT analog drivers to medical rehabilitation training equipment can greatly enhance the diversity of training functions of rehabilitation training equipment.
[0003] Rehabilitation medicine is an important branch of preventive medicine. The most skilled doctors are not those who are good at curing diseases, but those who can prevent diseases from happening. In rehabilitation medicine, there are generally three forms of prevention strategies. The purpose of rehabilitation training is the same. Using the three-level prevention thinking, therapists identify the root cause of the problem by screening and assessing risks, and use various training methods to solve the problems before they occur, so as to achieve twice the result with half the effort and keep you away from the risk of various injuries. Many patients think that it takes a hundred days to heal a broken bone, and lying in bed for three months will naturally restore their range of motion and strength. They missed the golden recovery period and waited until they had no choice to seek help from professionals.
[0004] The Chinese invention patent discloses an ankle-foot rehabilitation training device and balance training system, with application publication number CN103961240A. The lower end of the front support plate of the ankle-foot rehabilitation training device is fixed on the bottom plate, the front sole pedal is hinged to the upper end of the front support plate, the front sole pedal and the rear sole pedal are hinged through the second pin shaft, the first-second pin holes are arranged at the bottom of the rear sole pedal, the first-second pin holes are respectively installed in the first-second pin holes, the first ball joint connects the first pin and the third pin respectively, the second ball joint connects the second pin and the fourth pin respectively, the third pin connects the first servo electric cylinder unit, the fourth pin connects the second servo electric cylinder unit, the first servo electric cylinder unit is connected to the bottom plate through the third ball joint, and the second servo electric cylinder unit is connected to the bottom plate through the fourth ball joint. The ankle-foot rehabilitation training device of the present invention can perform rehabilitation training on the patient's ankle joint and metatarsophalangeal joint of the foot respectively. The balance training system changes the patient's center of gravity position through the ankle-foot rehabilitation training device to perform balance training.
[0005] The disadvantage of this patent is that the person rides on the seat, holds the armrests with both hands, and places both feet on the ankle and foot rehabilitation training device, and the first servo electric cylinder unit and the second servo electric cylinder unit are raised and lowered to achieve the purpose of exercising the ankle and foot. For patients with ankle and foot injuries who cannot move, this structure increases the difficulty of the patient to stand and is inconvenient to operate; the first servo electric cylinder unit and the second servo electric cylinder unit cannot control the speed and cannot achieve the purpose of uniform lifting and lowering; the base needs to be fixed on the ground in a stable position, otherwise it will roll over, making it inconvenient to move; in view of the above technical problems, further technical improvements need to be made to facilitate medical rehabilitation training, which is a technical problem that needs to be solved urgently.
