Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation devices, and particularly to a new linkage training system capable of improving muscle atrophy training, especially a linkage muscle atrophy improvement training system. Background Art

[0002] Muscle atrophy, also known as muscular atrophy, refers to the dystrophy of striated muscle, where muscle fibers become thinner or even disappear, leading to a reduction in muscle volume. Muscle atrophy is mostly caused by muscle diseases or nervous system dysfunctions. Common clinical manifestations include thigh muscle atrophy, calf muscle atrophy, and scapular muscle atrophy. In addition, severe muscle atrophy can lead to weakened breathing and respiratory function decline.

[0003] Among them, disuse muscle atrophy caused by frequent bed rest and inactivity can be improved clinically through rehabilitation devices to reduce or delay the time of symptom aggravation, and at the same time, combined with clinical drug treatment to further achieve the purpose of improvement and treatment.

[0004] In the existing technology, there are currently many rehabilitation devices for improving and alleviating muscle atrophy. For example, in the patent document with the patent application number CN201910685524.1, a device and method for alleviating leg muscle atrophy are disclosed. Its main structure includes a trough body, a pump, a riding device, and sensors. The riding device is arranged above the trough body, and the pump is connected to the trough body; the number of riding devices is at least one; sensors are arranged before and after the riding device, and the sensors are connected to a timer and a counter.

[0005] It mainly places the legs naturally in water and adjusts the water flow direction to make the legs pass through the fence forward or backward reciprocally and count times to achieve the purpose of leg exercise. This simple method relying on water flow obstruction and load cannot achieve the purpose of weight-bearing training in actual use. When the water flow is small, it will not form the effect of load exercise, and when the water flow is large, it will cause excessive skin irritation to the patient. Generally speaking, it cannot achieve the purpose of weight-bearing training in actual use and is difficult to achieve the training effect.

[0006] For another example, in the patent document with the patent application number CN202111617837.7, a rehabilitation device for leg muscle atrophy after rehabilitation in the rehabilitation department is also disclosed. Its main structure includes a bottom plate and support columns, with support columns arranged on both sides of the bottom plate; a large connecting plate, with a large connecting plate placed on the top of the bottom plate; a housing, with a housing arranged on the top of the large connecting plate; a riding mechanism, with a riding mechanism arranged on the housing; a clamping mechanism, with a clamping mechanism arranged on the housing, and the clamping mechanism cooperates with the riding mechanism; a seat mechanism, with a seat mechanism arranged on one of the support columns.

[0007] As can be seen from the above-mentioned rehabilitation device for leg muscle atrophy in the rehabilitation department, it actually uses a method similar to cycling to train the legs. However, it requires manual pedaling of the cycling mechanism, which can have a certain effect on rehabilitation patients in the middle or late stages of treatment with certain mobility, but it is not suitable for bedridden patients still suffering from muscle atrophy. Such patients lack leg strength and are unable to independently operate and apply the above device. Therefore, the above-mentioned rehabilitation device is not applicable in the initial stage of treatment either.

[0008] For this reason, the present invention has conducted research and improvement on the initial training and treatment improvement of muscle atrophy patients, and thus proposes a new system that can be applied to muscle atrophy patients at all stages to better solve the problems existing in the prior art.

[0023] The present invention also provides a method for analyzing and processing the improvement state of the leg muscles of patients with muscle atrophy by using the above-mentioned linkage type muscle atrophy improvement training system, including the following steps:

[0024] Obtain the medial perspective frontal view following training video and the lateral perspective frontal view following training video of the patient during a certain use of the above-mentioned linked muscle atrophy improvement training system. When training, the patient should appropriately expose the thighs and the entire calf area;

[0025] Among them, the medial perspective frontal view following training video is used to record the transformation state of the patient's left leg during training from the medial side, and the lateral perspective frontal view following training video is used to record the transformation state of the patient's right leg during training from the lateral side, so as to better record the force change state of the muscle groups of both legs during the training state;

[0026] Import the medial perspective frontal view following training video and the lateral perspective frontal view following training video into video capture software, and sequentially obtain multiple left leg low-position screenshot photos of the patient's feet in the lowest extended state and multiple left leg high-position screenshot photos of the patient's feet in the highest extended state in the medial perspective frontal view following training video; at the same time, obtain multiple right leg low-position screenshot photos of the patient's feet in the lowest extended state and multiple right leg high-position screenshot photos of the patient's feet in the highest extended state in the lateral perspective frontal view following training video;

[0027] Number the multiple obtained left leg low-position screenshot photos, multiple left leg high-position screenshot photos, multiple right leg low-position screenshot photos, and multiple right leg high-position screenshot photos in sequence; among them, the left leg low-position screenshot photos are numbered as A1 左低 、A2 左低 、A3 左低 、……、An 左低 ; The left leg high-position screenshot photos are numbered as A1 左高 、A2 左高 、A3 左高 、……、An 左高 ; The right leg low-position screenshot photos are numbered as A1 右低 、A2 右低 、A3 右低 、……、An 右低 ; The left leg high-position screenshot photos are numbered as A1 右高 、A2 右高 、A3 右高 、……、An 右高 ;

[0029] Extract the corresponding leg contour of the current binarized image and establish an edge algorithm to obtain the precise edge area of the leg contour, and delete the area outside the edge area;

[0030] For each leg contour obtained within each precise edge region, mark the angle between the thigh and the calf and export and record the angle degree.

[0031] Repeat the above steps to complete the processing of the remaining pictures in sequence.

[0032] After exporting the angle data of each corresponding leg of the patient, take the average value to obtain the left leg average extension angle data and the right leg average extension angle data of the patient during the current training.

[0033] Repeat the above steps, calculate the corresponding left leg average extension angle data and right leg average extension angle data in multiple trainings in the recent month with a one-month cycle, and upload them to the case database of the Internet medical platform.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] 1. This system can carry out improvement training for patients with leg muscle atrophy. During the training process, it can be adjusted according to the preset damping resistance to carry out appropriate training for patients with different severities, improving the scientific nature of the training and the universality for different patients.

[0036] 2. When the entire training system is used for patients in the lying supine position, the flipping angle of the flipping locking mechanism can be adjusted according to the training needs. Adjusting to different angles can enable patients to achieve different training effects during the foot-pedaling pushing position, ensuring the training matching for different patients and the training intensity matching for the same patient at different times, and the linkage effect during the overall training is better.

[0037] 3. In this system, two methods are adopted for leg training. One is the foot-pedaling pushing position method to achieve training with different pushing amplitudes, and the other is the foot-pedaling bicycle method to achieve bicycle training to promote the cooperation degree of the two legs. The two training methods cooperate with each other to achieve a better training effect and effectively improve the muscle atrophy symptoms of patients.

[0038] 4. This system also matches a special training effect analysis method. Through the method in the present invention, the average angle data of the thigh and calf during the foot-pedaling pushing position training of patients can be effectively counted and uploaded as health data for later medical treatment, effectively ensuring the scientific recording of the training and rehabilitation process.

Detailed implementation mode

[0048] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention. The specific structure of the present invention is as Figures 1-7 shown in the figure.

[0049] Embodiment 1:

[0050] A linkage type muscle atrophy improvement training system is placed near the tail of the lying position A of the patient. The linkage type muscle atrophy improvement training system includes a lifting table assembly fixedly placed on the ground. A flipping and locking mechanism is installed on the top of the lifting table assembly. A lower limb pedaling training mechanism is arranged on the flipping and locking mechanism. The trainer in the lying position A pedals the lower limb pedaling training mechanism to exercise the leg muscles. A position control driving component is fixedly installed on the top of the lifting table assembly at the right end of the flipping and locking mechanism. The position control driving component is used to drive the flipping and locking mechanism to flip at different angles and self-lock after flipping in place.

[0051] When the entire linkage muscle atrophy improvement training system is used in conjunction with a patient in the supine position, it can adjust and control the lifting table assembly according to the height at which the current patient is lying flat, so as to achieve the purpose of lifting to an appropriate height. After the height adjustment is in place, with the help of nursing staff, the patient's legs can be brought close to the lower limb pedaling training mechanism of the system and rely on both feet to pedal on the lower limb pedaling training mechanism. At this time, the position control drive assembly is controlled to operate according to the patient's comfort level and the current condition, and finally achieve the purpose of adjusting the tilting lock mechanism to flip to a suitable tilting angle and self-lock.

[0052] After the position adjustment operation before training, rely on the patient's legs to exert force and use the foot pedal to push the lower limb pedaling training mechanism to perform leg rehabilitation training back and forth. Before the patient's training, the resistance on the lower limb pedaling training mechanism can be adjusted as needed to achieve the purpose of matching the patient's exercise load amplitude.

[0053] In a preferred embodiment of any of the above solutions, the lifting table assembly includes a non-slip base 1 fixed on the ground. Above the non-slip base 1, a lifting platform 2 is provided. At the four corners of the bottom of the lifting platform 2, a synchronous lifting electric cylinder 3 is respectively fixedly installed. The four synchronous lifting electric cylinders 3 are in a synchronous and same-direction movement state during movement. The top of the piston rod of each synchronous lifting electric cylinder 3 is fixedly installed at the bottom of the lifting platform 2, and the bottom of the cylinder barrel of each synchronous lifting electric cylinder 3 is respectively fixedly installed at the top of the non-slip base 1. The tilting lock mechanism is installed on the top of the lifting platform 2.

[0054] When the lifting table assembly is adjusted, it is mainly adjusted according to the height of the current patient in the supine position. During adjustment, each synchronous lifting electric cylinder 3 is remotely controlled to lift to different heights to drive the lifting platform 2 and the components thereon to reach a suitable position. After the adjustment is completed, self-locking is achieved by relying on the four synchronous lifting electric cylinders 3.

[0055] Preferably, in any of the above solutions, the flipping and locking mechanism includes a left bearing seat 4 and a right bearing seat 5 that are respectively and fixedly installed at intervals on the top of the lifting platform 2 of the lifting table assembly. An adjusting and locking lead screw 6 is installed between the left bearing seat 4 and the right bearing seat 5. The stepped shaft sections 601 at both ends of the adjusting and locking lead screw 6 respectively pass through the left bearing seat 4 and the right bearing seat 5 at corresponding positions. The stepped shaft section 601 passing through the right bearing seat 5 is connected to the position control drive assembly through a coupling. A moving slide 7 is screwed on the outer side wall of the adjusting and locking lead screw 6. The bottom of the moving slide 7 abuts against the top of a connecting plate 8. The connecting plate 8 fixedly connects the left bearing seat 4 and the right bearing seat 5. A supporting link 9 is symmetrically hinged on the inner and outer sides of the moving slide 7 respectively; on the inner and outer sides of the top of the left bearing seat 4, vertical supporting seats 10 are symmetrically and fixedly installed respectively. The left and right ends of an inclined flipping and supporting seat 11 are fixedly welded with a flipping and rotating main shaft 12 respectively. The two flipping and rotating main shafts 12 respectively pass through the mounting holes of the vertical supporting seats 10 at corresponding positions and extend out of the corresponding vertical supporting seats 10. A upper connecting ear seat 13 is welded and fixed at the bottom of the middle section of the flipping and supporting seat 11. The upper ends of the two supporting links 9 are respectively hinged to the inner and outer sides of the upper connecting ear seat 13 through hinge shafts; the lower limb pedaling training mechanism is installed on the flipping and supporting seat 11.

[0056] The flipping of the flipping and locking mechanism refers to the flipping angle of the flipping and supporting seat 11 hinged thereon. During adjustment, the operation of the position control drive assembly is relied on to drive the adjusting and locking lead screw 6 to rotate forward or backward as needed. During the rotation process, the configured angle sensor 31 can record the inclination angle when stopped currently, which is convenient for comprehensive recording with the training state and clearly records the training carried out under what inclination state.

[0057] The rotation of the adjusting and locking lead screw 6 will drive the forward and backward movement of the moving slide 7 that cooperates with it, thereby pushing the two hinged supporting links 9 to abut against or pull the middle part of the flipping and supporting seat 11 hinged at their upper ends, so as to drive the entire flipping and supporting seat 11 to rotate around the vertical supporting seat 10 hinged at its front end, so as to achieve the purpose of controlling the inclination angle of the flipping and supporting seat 11. When the position control drive assembly stops, the adjusting and locking lead screw 6 will be used for real-time locking. After the position adjustment is completed, the patient can perform the foot-pedaling and pushing training.

[0058] Preferably, in any of the above solutions, the position control driving assembly includes a motor base 14 fixedly installed on the top of the lifting platform 2. A position adjustment motor 15 is fixedly installed on the top of the motor base 14. The output end of the position adjustment motor 15 is connected to the stepped shaft section 601 of the adjustment locking screw 6 through a coupling, and the adjustment locking screw 6 is driven to rotate by the operation of the position adjustment motor 15.

[0059] When the position control driving assembly works, the power is transmitted to the corresponding adjustment locking screw 6 by the operation of the position adjustment motor 15, and the rapid adjustment of the inclination angle of the flipping support seat 11 is realized by relying on the rotation of the adjustment locking screw 6.

[0060] Preferably, in any of the above solutions, front pulley grooves 16 and rear pulley grooves 17 are respectively and spacedly arranged at the front end and the rear end positions of the lower limb pedaling training mechanism; the lower limb pedaling training mechanism includes front replacement guide pulleys 18 respectively arranged in the front pulley grooves 16. The pulley shafts 19 of the front replacement guide pulleys 18 are all movably inserted into the mounting holes of the front pulley grooves 16 at corresponding positions. Rear replacement guide pulleys 20 are respectively arranged in the rear pulley grooves 17. The pulley shafts 19 of the rear replacement guide pulleys 20 are all movably inserted into the mounting holes of the rear pulley grooves 17 at corresponding positions; A tear-resistant and tensile-resistant belt 21 is cooperatively installed between each of the front replacement guide pulleys 18 and the rear replacement guide pulley 20 opposite thereto. The upper belts of the tear-resistant and tensile-resistant belts 21 are all located above the moving slide 7, and the lower belts of the tear-resistant and tensile-resistant belts 21 are all located below the moving slide 7. A sliding installation long groove 22 is arranged in the middle of the top of the flipping support seat 11. At the front end of the sliding installation long groove 22, a foot force application member B is abutted and arranged on the top of the flipping support seat 11. The foot force application member B is used for placing the patient's feet, and the patient realizes forward force application and displacement by pedaling the foot force application member B. The inner and outer sides of the foot force application member B are respectively fixed to the upper belts of the tear-resistant and tensile-resistant belts 21 at corresponding positions. An adjustable hydraulic damper 23 is fixedly installed in the sliding installation long groove 22 at the rear side. The preset force of the adjustable hydraulic damper 23 is adjustable and it is in a fully extended state under natural conditions. The front end of the push rod of the adjustable hydraulic damper 23 is fixedly connected to the lower part of the foot force application member B. The foot force application member B can move backward and upward along the sliding installation long groove 22 only after overcoming the preset force of the adjustable hydraulic damper 23 and forcing the adjustable hydraulic damper 23 to contract.

[0061] The foot force application component B in the lower limb pedaling training mechanism set here mainly serves as the bearing point for the patient to exert force. Relying on the patient's feet to pedal the foot force application component B, various resistances are overcome to drive the foot force application component B to reciprocate along the length direction of the sliding installation long groove 22; the preset force of the adjustable hydraulic damper 23 can be adjusted in advance according to the patient's condition, so as to achieve the purpose of driving the adjustable hydraulic damper 23 to retract with an appropriate driving force; at the same time, tear-resistant and tensile belts 21 are also matched on both sides of the foot force application component B. The movement of the foot force application component B will drive the two tear-resistant and tensile belts 21 to rotate accordingly, so as to achieve the purpose of increasing the training load.

[0062] The preset foot-pedaled pushing amplitude ensures that there is no mutual collision or interference among the components during the movement process, ensuring the mutual cooperation and linkage of the components.

[0063] Preferably, in any of the above solutions, load regulation mechanisms C are respectively fixedly installed at the bottoms of the flipping support seats 11 at the rear sides of the lower layers of the tear-resistant and tensile belts 21. The front ends of the load regulation mechanisms C are respectively fixedly connected to the leading ends of the lower layers of the tear-resistant and tensile belts 21 at the corresponding positions, and the rear ends of the load regulation mechanisms C are respectively fixedly connected to the trailing ends of the lower layers of the tear-resistant and tensile belts 21 at the corresponding positions; the two load regulation mechanisms C are in a synchronous movement state during the working state.

[0064] The main purpose of the load regulation mechanism C is to add an adjustable training intensity mechanism on the basis of the upper adjustable hydraulic damper 23, effectively adapting to the training needs of patients in different periods; at the same time, it can also be used as a physical training device.

[0065] Preferably, in any of the above solutions, the load control mechanism C includes a lower positioning frame 44 fixedly installed at the bottom of the flipping support base 11. At the bottom of the lower positioning frame 44, two oppositely arranged and fixedly installed closing hydraulic cylinders 43 are symmetrically arranged. The opposite ends of the cylinders of the two closing hydraulic cylinders 43 are respectively abutted against each other. The piston rods of the two closing hydraulic cylinders 43 are respectively fixedly connected to the corresponding ends of the tear-resistant and tensile belt 21 at the corresponding positions. The two closing hydraulic cylinders 43 do not need to be connected to a hydraulic station for use. On the cylinder of each closing hydraulic cylinder 43, a front oil port 24 and a rear oil port 25 are respectively arranged. The two front oil ports 24 of each closing hydraulic cylinder 43 are connected through a first closed pipeline 26. The two rear oil ports 25 of each closing hydraulic cylinder 43 are connected through a second closed pipeline 27. A first pressure control valve 28 is arranged on the first closed pipeline 26, and a second pressure control valve 29 is arranged on the second closed pipeline 27. The forming range of each closing hydraulic cylinder 43 is located between the front oil port 24 and the rear oil port 25 on it. By adjusting the opening degrees of the first pressure control valve 28 and the second pressure control valve 29, the telescopic resistance of the piston rods of each closing hydraulic cylinder 43 is adjusted. Under normal conditions, one of the two closing hydraulic cylinders 43 is in a fully extended state and the other is in a fully retracted state.

[0066] When the load control mechanism C works, it mainly relies on the cooperation of the two closing hydraulic cylinders 43 configured on the two tear-resistant and tensile belts 21 to adjust the pulling resistance. Each of the two oppositely arranged closing hydraulic cylinders 43 configured on each tear-resistant and tensile belt 21 here is in a structure of being interconnected and hermetically sealed as a whole. The whole structure does not need to be equipped with additional power such as a hydraulic station. Since the cylinders of the two closing hydraulic cylinders 43 are both in a fixed state, when subjected to tensile force or thrust, only the piston rods on the two closing hydraulic cylinders 43 can be telescopic to match the tear-resistant and tensile belt 21, and the tear-resistant and tensile belt 21 that matches the respective front reversing pulleys 18 and rear reversing pulleys 20 rotates around it to achieve the purpose of following the displacement of the foot force component B.

[0067] When the piston rod of one of the two closing hydraulic cylinders 43 on the same tear-resistant and tensile belt 21 extends, it will compress the internal space of the current closing hydraulic cylinder 43, so that the oil in the internal space of the closing hydraulic cylinder 43 will be introduced into the internal space of another adjacent closing hydraulic cylinder 43 through the current first closed pipeline 26 or second closed pipeline 27, thus forcing the internal space of the closing hydraulic cylinder 43 to increase and forcing the piston rod at that place to retract.

[0068] The two closed hydraulic cylinders 43 designed herein achieve the linkage of the entire closed space through the first closed pipeline 26 and the second closed pipeline 27. The piston rods of the two closed hydraulic cylinders 43 are in a fully extended state and a fully retracted state respectively under normal conditions, and the movement states of the piston rods of the two closed hydraulic cylinders 43 always maintain the state of opposite movement.

[0069] By adjusting the opening degrees of the first pressure control valve 28 and the second pressure control valve 29, the telescopic resistance of the piston rods of the respective closed hydraulic cylinders 43 can be adjusted, so as to achieve the purpose of adjusting the liquid flow resistance.

[0070] Preferably, in any of the above solutions, a reflection type distance sensor 30 is fixedly installed on each of the flipping support seats 11 on both sides of the adjustable hydraulic damper 23. The two reflection type distance sensors 30 collect distance change signals and upload them.

[0071] The main purpose of the reflection type distance sensor 30 provided herein is to measure the moving distance of the adjustable hydraulic damper 23 by reflection ranging, so as to measure the movement amplitude of the patient when in the foot pedaling and pushing position, and upload the distance change signals collected by the reflection type distance sensor 30 to effectively record the movement amplitude.

[0072] Preferably, in any of the above solutions, an angle sensor 31 is fixedly installed on the outer side wall of the outer vertical support seat 10. The angle sensor 31 is fixedly connected to the outer end surface of the flipping rotating main shaft 12 at the corresponding position. The angle sensor 31 is used to detect the included angle between the current flipping support seat 11 and the horizontal plane and upload the detection result.

[0073] The angle sensor 31 can measure the angle of rotation of the flipping rotating main shaft 12 during the adjustment process, so as to measure the inclination angle of the flipping support seat 11, facilitate calculating the load component according to the specific inclination angle of the flipping support seat 11 obtained by measurement, so as to facilitate controlling the training amplitude. The damping resistance corresponding to each inclination angle state is designed with corresponding values to meet the needs of patients with different degrees of muscle atrophy, and at the same time, different degrees of training can be realized for the same patient.

[0074] Preferably, in any of the above solutions, the foot force application component B includes an inclined sliding footrest 32. A pushing slider 33 is fixedly installed at the bottom of the sliding footrest 32. The pushing slider 33 is slidably fitted in the corresponding sliding installation long groove 22. A supporting surrounding plate 34 is fixedly arranged around the top of the rear end of the sliding footrest 32. The rear side surface of the sliding footrest 32 is inclined upward and a plurality of anti-slip convex blocks 35 are fixedly arranged on its surface.

[0075] By having the patient step on the inclined surface of the sliding footrest 32, pushing the sliding footrest 32 forward and the supporting apron 34, it is possible to overcome the damping resistance and frictional resistance by the foot force, and ultimately achieve the purpose of driving the sliding block 33 to slide within the sliding installation long groove 22.

[0076] When the patient's feet step on the surface of the sliding footrest 32, the purpose of anti-slip positioning can be achieved by relying on each anti-slip bump 35.

[0077] At the bottom of the flipping support seat 11 below the foot force generating component B, a telescopic footrest mechanism D is further installed. The telescopic footrest mechanism D includes a T-shaped long groove 36 fixedly installed at the bottom of the flipping support seat 11. The T-shaped long groove 36 is arranged through the width direction of the flipping support seat 11. A two-way extending double-rod out-of-phase extending cylinder 37 is fixedly installed on the flipping support seat 11 in the middle of the T-shaped long groove 36. A T-shaped sliding seat 38 is respectively slidably clamped in the T-shaped long groove 36 on both sides of the double-rod out-of-phase extending cylinder 37. A rotary damper 39 is respectively fixedly installed at the bottom of each T-shaped sliding seat 38. The inner ends of each rotary damper 39 are respectively fixedly connected to the piston rods of the double-rod out-of-phase extending cylinder 37 at the corresponding positions. The double-rod out-of-phase extending cylinder 37 drives the rotary dampers 39 on both sides thereof to approach or move away from each other through the relative or opposite telescoping of the two piston rods. A rotary crank 40 is installed at the output end of each rotary damper 39. A bicycle foot pedal assembly 41 is respectively movably hinged at the end of each rotary crank 40. The width between the two bicycle foot pedal assemblies 41 is adjustable.

[0078] In this system, the designed lower limb pedaling training mechanism mainly uses foot pedaling force to drive the entire foot force generating component B to overcome resistance, so as to achieve the purpose of driving the entire foot force generating component B to slide along the sliding installation long groove 22. This exercise method mainly uses the method of linear foot pedaling force to achieve the purpose of training the leg force amplitude of the patient.

[0079] Here, a telescopic footrest mechanism D is also designed. Its main purpose is to use another method similar to the foot pedal of a bicycle to achieve the purpose of exercising the coordination ability of the two legs and promoting the rehabilitation of the leg muscle groups.

[0080] In addition, the telescopic footrest mechanism D relies on the telescoping of the double-rod out-of-phase extending cylinder 37 in the middle to drive the rotary damper 39 to approach or move away, so as to achieve the purpose of driving the bicycle foot pedal assemblies 41 to approach or move away from each other; when the distance between the two bicycle foot pedal assemblies 41 changes, the two legs of the patient can achieve different degrees of spreading distances, and ultimately achieve bicycle foot pedaling training in different states.

[0081] The training of leg strength is achieved by the way of directly pushing the pedals. At the same time, the two bicycle pedal components 41 are used for bicycle pedal training to achieve the purpose of training the harmony degree of both legs, and the comprehensive training is to improve the overall training effect.

[0082] Embodiment 2: Compared with Embodiment 1, it further includes: Follow-up cameras 42 are symmetrically arranged on the ground on the inner and outer sides of the foot force application component B respectively. The two follow-up cameras 42 move synchronously and are respectively used to shoot the follow-up training videos of the foot force application component B in the state of being cyclically pushed by the patient.

[0083] The main purpose of the follow-up cameras 42 arranged here is to shoot the videos of the front view and side view of the thigh and calf in a relaxed state facing the foot force application component B in the directly pushing state as needed, so as to facilitate the intuitive observation of the angle changes of different amplitudes between the thigh and calf of the patient in the direct pushing training in the later stage. On the premise of the only variable, by observing the angle changes between the thigh and calf, the force application degree and force application amplitude of the patient in the training can be indirectly reflected.

[0084] Specific working principle:

[0085] When the entire linkage type muscle atrophy improvement training system is used in cooperation with a patient in the supine position, the lifting platform component can be adjusted and controlled according to the height of the patient lying flat at present, so as to achieve the purpose of lifting to an appropriate height; when the height adjustment is in place, with the help of the nursing staff, the patient's legs can be brought close to the lower limb pedaling training mechanism of the system and rely on both feet to pedal on the lower limb pedaling training mechanism. At this time, the position control driving component is controlled to operate according to the comfort of the patient and the current condition, and finally the purpose of adjusting the tilting locking mechanism to turn to a suitable tilting angle and self-locking is achieved.

[0086] After the positioning operation before training is completed, rely on the patient's legs to exert force and use the foot to push the lower limb pedaling training mechanism to perform leg rehabilitation training back and forth; before the patient's training, the resistance on the lower limb pedaling training mechanism can be adjusted according to needs to achieve the purpose of matching the movement load amplitude of the patient.

[0087] Among them, the foot force - generating component B in the lower - limb pedaling training mechanism mainly serves as the load - bearing point for the patient's force generation. Relying on the patient's feet to pedal the foot force - generating component B, various resistances are overcome to drive the foot force - generating component B to reciprocate along the length direction of the sliding - mounting long groove 22; the preset force of the adjustable hydraulic damper 23 can be pre - adjusted according to the patient's condition, so as to achieve the purpose of driving the adjustable hydraulic damper 23 to retract with an appropriate driving force; meanwhile, on both sides of the foot force - generating component B, tear - resistant and tensile belts 21 are also matched. The movement of the foot force - generating component B will drive the two tear - resistant and tensile belts 21 to operate accordingly, so as to achieve the purpose of increasing the training load. Specifically, the lower - limb pedaling training mechanism mainly uses foot - pedaling force to drive the entire foot force - generating component B to overcome resistance, so as to drive the entire foot force - generating component B to slide within the sliding - mounting long groove 22. This exercise method mainly uses the way of straight - line foot - pedaling force to achieve the purpose of training the patient's leg force amplitude. In addition, a telescopic foot - pedal mechanism D is designed in the system. It mainly uses another way similar to the foot - pedal of a bicycle to achieve the purpose of exercising the coordination ability of both legs, and plays a role in promoting the rehabilitation of the leg muscle groups. The telescopic foot - pedal mechanism D relies on the expansion and contraction of the double - rod opposite - direction extending cylinder 37 in the middle to drive the rotary damper 39 to approach or move away, so as to drive the bicycle foot - pedal assemblies 41 to approach or move away from each other; when the distance between the two bicycle foot - pedal assemblies 41 changes, the two legs of the patient can reach different degrees of spreading distances, and finally achieve bicycle foot - pedaling training in different states. The way of straight - pushing with the foot - pedal realizes the training of leg force, and at the same time, the bicycle foot - pedal training of the two bicycle foot - pedal assemblies 41 achieves the purpose of training the harmony degree of both legs, and the comprehensive training achieves the purpose of improving the overall training effect.

[0088] Embodiment 3:

[0089] Compared with Embodiment 1, this embodiment further includes:

[0090] A method for analyzing and processing the improvement state of the leg muscles of patients with muscle atrophy by using the above - mentioned linkage - type muscle atrophy improvement training system, including the following steps:

[0091] Obtain the front - view follow - up training video from the medial perspective and the front - view follow - up training video from the lateral perspective of the patient in a certain training state of using the above - mentioned linkage - type muscle atrophy improvement training system. When training, the patient should appropriately expose the thigh and the entire calf.

[0092] The purpose of exposing the thigh and the entire calf is to intuitively observe the changes in the extension angles of the patient's thigh and calf under the movement turntable and the changes in the muscle groups thereon, and better record the patient's leg muscles, leg strength, and force - generating degree.

[0093] Among them, the medial-view frontal following training video is used to record the transformation state of the patient's left leg in the training state from the medial side, and the lateral-view frontal following training video is used to record the transformation state of the patient's right leg in the training state from the lateral side, so that the force change state of the muscle groups of both legs in the training state can be better recorded.

[0094] Import the medial-view frontal following training video and the lateral-view frontal following training video into the video capture software, and successively obtain multiple left-leg low-position screenshot photos of the patient's feet in the lowest extended state and multiple left-leg high-position screenshot photos of the patient's feet in the highest extended state in the medial-view frontal following training video; at the same time, obtain multiple right-leg low-position screenshot photos of the patient's feet in the lowest extended state and multiple right-leg high-position screenshot photos of the patient's feet in the highest extended state in the lateral-view frontal following training video.

[0095] Capture multiple photos at different positions of the left leg or the right leg to better select the amplitude control of the low position and the high position during the same pushing movement, so as to facilitate the comparison and control of the leg stretching amplitude, and thus better record the amplitude control of the patient in the training state. The recording and analysis under multiple training states can better and objectively analyze the patient's training state and the true state of force application.

[0096] Successively number the multiple left-leg low-position screenshot photos, multiple left-leg high-position screenshot photos, multiple right-leg low-position screenshot photos, and multiple right-leg high-position screenshot photos obtained above; among them, the left-leg low-position screenshot photos are successively numbered as A1 左低 、A2 左低 、A3 左低 、……、An 左低 ; the left-leg high-position screenshot photos are successively numbered as A1 左高 、A2 左高 、A3 左高 、……、An 左高 ; the right-leg low-position screenshot photos are successively numbered as A1 右低 、A2 右低 、A3 右低 、……、An 右低 ; the left-leg high-position screenshot photos are successively numbered as A1 右高 、A2 右高 、A3 右高 、……、An 右高 ; where n is a natural number greater than or equal to 3;

[0097] Successively perform binary image processing on each of the numbered multiple left-leg low-position screenshot photos, multiple left-leg high-position screenshot photos, multiple right-leg low-position screenshot photos, and multiple right-leg high-position screenshot photos.

[0098] Extract the corresponding leg contour from the currently binarized image and establish an edge algorithm to obtain the precise edge region of the leg contour, and delete the area outside the edge region.

[0099] The binarized image processing combined with the edge algorithm can better ensure the effective interception of the required object and guarantee the effect of edge interception.

[0100] Mark the angle between the thigh and the calf of the leg contour obtained in each precise edge region in turn and export and record the angle degree.

[0101] Repeat the above steps to complete the processing of the remaining pictures in turn.

[0102] After exporting the angle data of each corresponding leg of the patient, take the average value to obtain the left leg average extension angle data and the right leg average extension angle data of the patient in the current training.

[0103] The left leg average extension angle data and the right leg average extension angle data can effectively reflect the average movement amplitude under the state of multiple straight leg pushing movements, so as to achieve the purpose of comprehensively reflecting the patient's movement state and exercise amount; in addition, when recording, the recorded data of the same group are all completed under the same inclination angle state.

[0104] Repeat the above steps, calculate the corresponding left leg average extension angle data and right leg average extension angle data in multiple trainings in the recent month with a one-month cycle and upload them to the case database of the Internet medical platform.

[0105] After uploading, it can better provide a true and reliable data reference for subsequent medical treatment, effectively monitor the patient's training state and muscle atrophy improvement state within a certain period, and facilitate the comprehensive analysis of the patient's rehabilitation situation in combination with the later diagnosis and treatment.

[0106] This system can conduct improvement training for patients with leg muscle atrophy. During the training process, appropriate training for patients with different severities can be achieved by adjusting the preset damping resistance, improving the scientific nature of the training and its universality for different patients. When the entire training system is used for patients in the lying supine position, the flipping angle of the flipping and locking mechanism can be adjusted according to the training needs. Adjusting to different angles can enable patients to achieve different training effects during the foot-pedaling and pushing positions, ensuring the training matching for different patients and the training intensity matching for the same patient at different times, and the linkage effect during the overall training is better. In this system, two methods are adopted for leg training. One is to use the foot-pedaling and pushing position method to achieve training with different pushing amplitudes, and the other is to use the foot-pedaling bicycle method to achieve bicycle training to promote the cooperation degree of both legs. The two training methods cooperate with each other to achieve a better training effect and effectively improve the muscle atrophy symptoms of patients. This system also matches a special training effect analysis method. Through the method in the present invention, the average included angle data of the thighs and calves during the foot-pedaling and pushing position training of patients can be effectively statistically recorded and uploaded as health data for later medical treatment, effectively ensuring the scientific recording of the training and rehabilitation process.
