Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a multifunctional lower limb rehabilitation training bracket. Background Art
[0002] As the aging problem becomes more and more prominent in my country, the number of people with cardiovascular and cerebrovascular diseases and nervous system diseases has also increased dramatically. Among them, the number of patients with lower limb motor dysfunction caused by central nervous system diseases such as spinal cord injury, cerebrovascular accident, brain trauma, and stroke has increased year by year. In addition, sports, car accidents, orthopedic diseases, muscle atrophy, etc. also lead to a large number of patients with lower limb motor dysfunction.
[0003] Patients with lower limb motor dysfunction often need to stay in bed for a long time. If patients stay in bed for a long time, it is easy to cause atrophy of the lower limb muscles and joint control muscles, stiffness and deformation of the joints, increased muscle tension, and spasms in severe cases. It is also easy to cause urinary tract infection, pressure sores, osteoporosis, venous thrombosis and other disuse syndromes.
[0004] Traditional lower limb rehabilitation methods include physical therapy, drug therapy, and manual-assisted training. Although these methods are effective to a certain extent, they also have some limitations. For example, manual-assisted training usually requires one-on-one guidance from a professional rehabilitation therapist, which is not only labor-intensive but also inefficient. At the same time, due to manpower limitations, it is difficult to achieve continuous and uniform force support, and long-term repetitive operations may also lead to inconsistent rehabilitation effects.
[0005] To solve these problems, medical device developers began to explore the use of mechanical devices to assist lower limb rehabilitation training. Such devices can provide continuous, adjustable motion stimulation and support, thereby helping patients to more effectively train muscle strength and coordination and accelerate the rehabilitation process. However, early rehabilitation devices were often complex in design, bulky, and expensive, limiting their popularity in clinics and homes. Utility Model Content

DETAILED DESCRIPTION
[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0033] like Figure 1-4 As shown, a multifunctional lower limb rehabilitation training bracket includes a shell 1, a driving mechanism 3 is arranged at the lower part of the shell 1, a lifting mechanism 4 is arranged at the upper part of the shell 1, the upper part of the driving mechanism 3 is in contact with the lower part of the lifting mechanism 4, and a skin 2 is arranged at the upper part of the shell 1.
[0034] In this embodiment, the lifting mechanism 4 includes a baffle 401, multiple limiting columns 402, multiple support blocks 403, multiple lifting rods 404, multiple springs 405 and multiple limiting grooves 406. The lower end of the support block 403 is fixedly connected to the upper part of the lifting rod 404 through three limiting columns 402. The outer periphery of the limiting column 402 is slidably connected to the middle part of the baffle 401. The left and right sides of the lifting rod 404 are slidably connected to the inside of the limiting groove 406. Multiple limiting grooves 406 are fixedly connected to the left and right inner walls of the upper part of the outer shell 1 at equal intervals. A sponge pad is arranged on the upper side of the middle part of the support block 403, a spring 405 is arranged on the outer periphery of the limiting column 402, and the spring 405 is arranged between the baffle 401 and the lifting rod 404. A plurality of air holes are arranged in the middle part of the skin 2.
[0035] Specifically, the driving reduction motor 301 drives the transmission shaft 305 to rotate through the pulley 303 and the belt 304, and then drives the cam 306 to rotate. Therefore, through the lifting of the cam 306, the lifting rod 404 drives the support block 403 to move upward through the limit column 402, so that the support block 403 supports the patient's legs. Every three adjacent cams 306 form a group, and the three cams 306 in each group are fixed on the periphery of the transmission shaft 305 in a circular array. Therefore, when the transmission shaft 305 is driven by the reduction motor 301 to rotate a certain angle, different support blocks 403 will be lifted up, thereby preventing the same support block 403 from contacting the legs for a long time, effectively preventing the occurrence of diseases such as pressure sores.
[0036] In this embodiment, the driving mechanism 3 includes a reduction motor 301, a protective shell 302, a pulley 303, a belt 304, a transmission shaft 305 and multiple cams 306. The front and rear ends of the transmission shaft 305 are rotatably connected to the front and rear sides of the lower part of the shell 1, and the middle parts of the multiple cams 306 are fixedly connected to the outer periphery of the transmission shaft 305. One side of the protective shell 302 is fixedly connected to the front side of the shell 1. The middle part of the pulley 303 is rotatably connected to the two ends inside the protective shell 302. The two ends inside the belt 304 are meshed and connected to the outer periphery of the pulley 303. The front end of the transmission shaft 305 passes through the shell 1 and the protective shell 302 and is fixedly connected to the middle part of one of the pulleys 303. The reduction motor 301 is installed on the outside of the shell 1. The output end of the reduction motor 301 passes through the protective shell 302 and is fixedly connected to the middle part of another pulley 303. The cams 306 correspond one to one to the lifting rod 404.
[0037] Specifically, the driving reduction motor 301 drives the transmission shaft 305 to rotate through the pulley 303 and the belt 304, and then drives the cam 306 to rotate. Therefore, through the lifting of the cam 306, the lifting rod 404 drives the support block 403 to move upward through the limit column 402, so that the support block 403 supports the patient's legs. Every three adjacent cams 306 form a group, and the three cams 306 in each group are fixed on the periphery of the transmission shaft 305 in a circular array. Therefore, when the transmission shaft 305 is driven by the reduction motor 301 to rotate a certain angle, different support blocks 403 will be lifted up, thereby preventing the same support block 403 from contacting the legs for a long time, effectively preventing the occurrence of diseases such as pressure sores.
[0038] Working principle:
[0039] When in use, the patient's legs are placed on the bracket, and the reduction motor 301 is driven to rotate the transmission shaft 305 through the pulley 303 and the belt 304, thereby driving the cam 306 to rotate. Through the lifting of the cam 306, the lifting rod 404 drives the support block 403 to move upward through the limit column 402, so that the support block 403 supports the patient's legs. Every three adjacent cams 306 form a group, and the three cams 306 in each group are fixed on the periphery of the transmission shaft 305 in a circular array. Therefore, when the transmission shaft 305 is driven by the reduction motor 301 to rotate a certain angle, different support blocks 403 will be lifted up, thereby exercising the lower limb muscles, promoting blood circulation, and effectively preventing the occurrence of diseases such as pressure sores.
[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
