Description

Technical Field

[0001] The present invention relates to the field of lower limb rehabilitation training equipment, and in particular to a multifunctional lower limb rehabilitation training equipment with lower limb sign recovery detection effect. Background Art

[0002] Leg injury is one of the most common clinical injuries. The disability rate of leg injury is high. Leg injury requires rehabilitation treatment after clinical surgery, but the effect of rehabilitation treatment has always troubled patients and medical staff. If the rehabilitation treatment effect is not good, it will seriously affect the patient's quality of life and the patient's ability to work, and have a great impact on the patient's life. Therefore, various manufacturers have been researching and manufacturing rehabilitation equipment with better rehabilitation treatment effects to help patients recover from leg injuries.

[0003] The existing lower limb rehabilitation training equipment itself lacks the function of detecting the recovery of physical signs after rehabilitation training. Generally, it is necessary to move to another location after training to perform functional detection of the degree of recovery of lower limb signs, which is not convenient enough. In addition, the existing lower limb rehabilitation training equipment will cause the trainees' legs to be tired or sore during the rehabilitation training process, and does not have the massage effect on the ankles and legs. The functionality of the lower limb rehabilitation training equipment needs to be further improved. Summary of the invention

[0004] The purpose of the present invention is to solve the problems raised in the above background technology, and then propose a multifunctional lower limb rehabilitation training device with lower limb sign recovery detection effect.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A multifunctional lower limb rehabilitation training device with lower limb sign recovery detection effect, comprising a frame, a roller, an operation screen, a backrest, a telescopic component, a foot pedal, a horizontally movable muscle strength detection component, an angle deflection component, a leg massage component, an auxiliary stepping component, an ankle swing component and an inertial sensor;

[0007] The frame is connected to a backrest through an angle deflection component so that the patient undergoing lower limb rehabilitation training can be in a sitting or standing position, and the angle deflection component cooperates with the muscle strength detection component to detect the recovery of lower limb muscle strength in a standing position;

[0008] A leg massage component is arranged in the backboard and the leg massage component is used to strike or continuously contact the back of the legs of the lower limb rehabilitation training patient for vibration massage, and the backboard is connected to a waist backpack through a telescopic component so that the legs of the lower limb rehabilitation training patients of different heights are all in the effective massage position of the leg massage component;

[0009] The waist backpack is symmetrically provided with joint motors, which are connected to the leg protectors through connecting rods. The leg protectors are provided with inertial sensors to detect the recovery of the range of motion of the lower limb joints.

[0010] The backing plate is connected with a foot pedal via an auxiliary step assembly, and the auxiliary step assembly cooperates with a joint motor to enable the foot pedal to slide up and down alternately along the backing plate;

[0011] The foot pedal is provided with an ankle swing component for supporting the feet of the lower limb rehabilitation training patient, and the ankle swing component swings left and right to relax the feet of the lower limb rehabilitation training patient.

[0012] Furthermore, the leg massage component includes an electric push rod, a striking plate, a convex rubber pad and a vibration motor. A fixing groove is opened on the support plate, and an electric push rod is arranged in the fixing groove. The electric push rod is connected to the striking plate matching the fixing groove, and the striking plate is provided with a convex rubber pad and a vibration motor.

[0013] Furthermore, the ankle swing assembly includes a servo motor, a rotating disk and a strap. The servo motor is arranged at the bottom of the pedal. The pedal is rotatably connected with a rotating disk, and the rotating disk is connected to the servo motor. The rotating disk is provided with a strap.

[0014] Furthermore, the auxiliary step assembly includes a four-stage cylinder and a slide rail, and the back plate is symmetrically provided with independently operated four-stage cylinders, and the four-stage cylinders are connected to a foot pedal that slides with the slide rail.

[0015] In the above scheme, the two pedals move up and down alternately while stepping on the spot, thereby maintaining the same frequency as the operation of the joint motor, that is, the pedals rise during leg bending and fall during leg extension, thereby further improving the effect of lower limb rehabilitation training and providing effective support.

[0016] Furthermore, the angle deflection assembly includes a fixed plate, a rotating shaft and a deflection cylinder. The fixed plate is symmetrically arranged on the frame, the fixed plate is rotatably connected to the rotating shaft and one end of the rotating shaft is welded to the support plate, the deflection cylinder is rotatably connected to the frame and the retraction rod of the deflection cylinder is rotatably connected to the support plate.

[0017] Furthermore, the muscle strength detection component includes an electric cylinder and a muscle strength detector. The frame is provided with the electric cylinder, and the electric cylinder is connected to the muscle strength detector.

[0018] Furthermore, the waist backpack is provided with shoulder straps and symmetrically and embeddedly distributed micro cylinders, the micro cylinders are connected to joint motors, the leg protectors are electromagnetically adsorbed to the connecting rods, and the backrest is symmetrically provided with grip rollers for easy grasping.

[0019] Furthermore, the leg protector is provided with an electromagnet, and the connecting rod is made of metal material and is provided with a mounting groove adapted to the size of the electromagnet.

[0020] Furthermore, a sleeve roller is arranged on the back plate, and an airbag massager is placed on the sleeve roller.

[0021] Furthermore, the telescopic assembly includes a cylinder and a connecting roller. The cylinder is symmetrically arranged on the back plate, and the cylinder is connected to the waist backpack through the connecting roller.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This device can detect the recovery of lower limb signs immediately after completing a period of lower limb rehabilitation training and provide real-time feedback on the results. There is no need for lower limb rehabilitation training personnel to move to another location. It can be completed directly on the lower limb rehabilitation training equipment. The operation is convenient. At the same time, lower limb rehabilitation training patients can be massaged in time to relieve symptoms after experiencing leg or ankle soreness, fatigue and discomfort.

[0024] 2. The device can also adaptively adjust the height of the waist backpack according to users of different heights so that the legs of different users are exactly in the effective massage area and in close contact with the leg massage components. It also has a posture adjustment function to facilitate the user's rehabilitation training in both standing and sitting scenarios. The lower limb rehabilitation training equipment has diverse functions and good effects.

[0025] 3. When the device is testing the recovery of lower limb signs and massaging the legs, the controller first controls the electromagnet to cut off the power, and then controls the micro-cylinder to move synchronously to both sides, so that the leg protector can be separated from the connecting rod, thereby reducing the weight. Subsequent users can move more lightly and flexibly during the lower limb sign recovery test or massage. BRIEF DESCRIPTION OF THE DRAWINGS

The electric cylinder 13 is arranged on the frame 1, and the electric cylinder 13 is connected to the muscle strength detector 14 for the lower limbs. The muscle strength detector 14 belongs to the prior art and its principle will not be described in detail.

[0047] Further refinement of the embodiments of the present invention is as follows: Figures 1 to 5 As shown, the telescopic assembly includes a cylinder 31 and a connecting roller 32 . The cylinder 31 is symmetrically arranged on the back plate 3 , and the retractable rod of the cylinder 31 is connected to the waist backpack 421 through the connecting roller 32 .

[0048] It should be noted that the operating screen 12, electric cylinder 13, muscle strength detector 14, deflection cylinder 23, telescopic assembly, four-stage cylinder 43, servo motor 51, electric push rod 54, vibration motor 57, joint motor 423 and inertial sensor 426 are all electrically connected to the controller. The controller is not shown in the figure and can be specifically arranged on the frame 1.

[0049] The workflow of the present invention is:

[0050] The initial backrest 3 is in a vertical state driven by the angle deflection component. First, the person steps on the foot pedals 45 with both feet to stand up, and then completes the wearing and fixing of the waist backpack 421, the shoulder straps 411 and the leg protectors 425 in sequence. The fixing method of the waist backpack 421, the shoulder straps 411 and the leg protectors 425 during the wearing process belongs to the existing technology and is not improved. After wearing, the lower limb rehabilitation training can be started immediately. During the lower limb rehabilitation training, the joint motor 423 can achieve the power assistance during the process of stepping in place, thereby reducing the user's fatigue. While stepping in place, the two foot pedals 45 alternately move up and down and keep the same frequency with the operation of the joint motor 423, that is, the foot pedal 45 rises during the bending of the legs, and the foot pedal 45 falls during the unfolding of the legs, thereby further improving the effect of the lower limb rehabilitation training and providing effective support;

[0051] If the user experiences leg or ankle fatigue and pain during lower limb rehabilitation training, the operation of the joint motor 423 can be stopped.

[0052] When a leg massage is needed, the electric push rod 54 and the vibration motor 57 are triggered to operate through the operation screen 12, and the electric push rod 54 drives the striking plate 55 to move outward, and then the back of the leg can be struck back and forth to relieve fatigue and promote blood circulation. In addition, the convex rubber pad 56 can be made to contact with the back of the leg and then continuously vibrate to relieve the pain. The two massage modes can be selected and switched to any mode as needed. However, before the massage, due to the different heights of different users, when the user is changed, the position of the waist backpack 421 can be changed by controlling the operation of the telescopic component so that the legs of users of different heights can stretch normally and unobstructed. At the same time, the legs are in an effective massage position to ensure the massage effect. After the massage, the airbag massager 62 can be worn for heating therapy, which has a better effect. When the airbag massager 62 is not in use, it can be placed on a sleeve roller 61 that is easy to take.

[0053] When ankle massage is needed, the four-stage air cylinder 43 and the joint motor 423 are stopped, and the servo motor 51 is controlled to operate to drive the rotating disk 52 to rotate, and the person's foot is placed on the rotating disk 52 and fixed by the strap 46 at the beginning, so that the person's ankle can drive the leg to swing slightly left and right with the operation of the servo motor 51, thereby relaxing the ankle to further relieve fatigue;

[0054] After a long period of lower limb rehabilitation training, the recovery of lower limb muscle strength and joint range of motion can be tested.

[0055] When performing a muscle strength test, the user is first allowed to stand, and then the electric cylinder 13 drives the muscle strength detector 14 to move to one side of the thigh or calf, and then the user applies force to the muscle strength detector 14 through the leg, and when the force is applied, the user's muscle strength recovery status will be displayed in real time on the operation screen 12;

[0056] When the joint activity test is performed, the joint motor 423 stops working, and the user begins to bend the knee joint of the leg autonomously. At this time, the inertial sensor 426 can detect the numerical value of the joint activity in real time and feed back the result to the operation screen 12. The detection principle of the inertial sensor 426 belongs to the prior art and is not described. Therefore, the user's physical sign recovery status can be directly detected on the lower limb rehabilitation training equipment. If the test result is qualified, the next stage of rehabilitation training can be carried out. If it is unqualified, it is necessary to communicate with medical staff in time for targeted adjustment or drug treatment;

[0057] Compared with the existing technology, the present device can immediately detect the recovery of lower limb signs and provide real-time feedback on the results after completing a period of lower limb rehabilitation training. There is no need for lower limb rehabilitation training personnel to move to another location, and the training can be completed directly on the lower limb rehabilitation training equipment. The operation is convenient, and at the same time, massage can be performed in time to relieve the symptoms of leg or ankle soreness, fatigue and discomfort in lower limb rehabilitation training patients. In addition, the height of the waist backpack 421 can be adaptively adjusted according to users of different heights so that the legs of different users are in the effective massage area and in close contact with the leg massage component. Finally, it also has a posture adjustment function to facilitate the user's rehabilitation training in both standing or sitting scenarios. The lower limb rehabilitation training equipment has diverse functions and good effects.

[0058] In some embodiments, the striking plate 55 is hollow inside and is provided with a heater, and a plurality of air holes are opened on the convex rubber pad 56, which is not shown in the figure; in this embodiment, the heater and the air holes can achieve heating of the legs during the leg massage process, thereby achieving a better massage and soothing effect, and no external auxiliary heating massage parts are needed.

[0059] In other embodiments, a micro cylinder 422 is symmetrically and embedded in the waist backpack, the micro cylinder 422 is connected to a joint motor 423, and the leg protector 425 is electromagnetically adsorbed to the connecting rod 424;

[0060] Further optimization of the above embodiment scheme, such as Figure 4 As shown, the leg protector 425 is provided with an electromagnet 427, and the connecting rod 424 is made of metal material and is provided with a mounting groove 428 that matches the size of the electromagnet 427; in this embodiment, during the test of the recovery of lower limb signs and the leg massage, the controller first controls the electromagnet 427 to cut off the power, and then controls the micro cylinder 422 to move to both sides synchronously, so that the leg protector 425 can be separated from the connecting rod 424, thereby reducing the weight, and the subsequent user can move more lightly and flexibly during the test of the recovery of lower limb signs or the massage.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
