Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training monitoring devices, and particularly to a rehabilitation training monitoring system for stroke patients. Background Art

[0002] One of the common sequelae of stroke is limb motor impairment. Relevant data shows that more than 85% of patients have varying degrees of limb motor impairment after onset, and doing a good job in rehabilitation exercise is the key to reducing stroke sequelae. Rehabilitation training is based on the process of the disease evolution.

[0003] Existing training methods cannot achieve real-time monitoring and evaluation. The rehabilitation training process more relies on the evaluation and analysis of therapists, and it is impossible to accurately quantify whether the patient's training movements are in place, whether the quality meets the standard, and whether there is compensation by the healthy limb to complete the task (such as whether the healthy limb compensates too much to complete the cycling task on the lower limb power bicycle, and whether the affected limb reaches the maximum strength that can be achieved currently, lacking the evaluation of muscle function data).

[0004] Moreover, there is no accurate data evaluation. Existing surface electromyography evaluations are more about before-and-after evaluations to quantify muscle function, and they fail to monitor the changes in muscle function data of the healthy and affected limbs during the cycling process on the power bicycle. Currently, devices on the market such as Monark 928E have data such as time, heart rate, METS (metabolic equivalent), L / min (minute ventilation volume), RPM (revolutions per minute), WATT (Wingate anaerobic power test), etc., lacking monitoring indicators for changes in muscle function of the healthy and affected limbs. There is also a lack of content for plantar pressure testing to reflect the work done by both sides of the patient. Summary of the Invention

[0005] In view of the above background art, existing surface electromyography evaluations are more about before-and-after evaluations to quantify muscle function, and they fail to monitor the changes in muscle function data of the healthy and affected limbs during the cycling process on the power bicycle, lacking monitoring indicators for changes in muscle function of the healthy and affected limbs, and also lacking content for plantar pressure testing to reflect the work done by both sides of the patient. Therefore, a technical solution for a rehabilitation training monitoring system for stroke patients is provided.

[0006] It includes a power bicycle mechanism, a plantar force monitoring component is arranged on the pedal of the power bicycle mechanism, two groups of lower limb muscle monitoring components are arranged above the power bicycle mechanism, and a wireless surface electromyograph is arranged on the side of the power bicycle mechanism;

[0007] The power bicycle mechanism includes a frame, cranks rotatably arranged on the left and right sides of the frame, and pedals rotatably connected to the ends of the cranks far from the frame. A seat is fixedly connected to the rear side of the upper surface of the frame;

[0008] The sole force monitoring component includes a U-shaped frame fixed on the left and right sides of the pedal, and an elastic band fixed on the upper surface of the U-shaped frame and spanning the pedal. A semiconductor pressure sensor is inlaid and fixed on the top surface of the pedal.

[0009] Each of the lower limb muscle monitoring components includes two binding bands respectively tied around the outer circles of the thighs and calves. 2-3 surface electromyogram electrode patches are inlaid on the inner surfaces of the binding bands. Specifically, the binding bands are successively tied around the calves and thighs of the left and right legs. The binding bands are firmly tied by the Velcro on the inner and outer surfaces of the binding bands, so that several surface electromyogram electrode patches on the inner surface of the binding bands are in contact with the muscles of the thigh and calf parts. When the foot is placed on the pedal, the foot is bound by the elasticity of the elastic band. At this time, the sole of the foot is in contact with the semiconductor pressure sensor.

[0010] The wireless surface electromyograph includes an electromyogram host and an electromyogram signal receiver connected to the signal receiving end of the electromyogram host through a wire harness. Specifically, when the person to be rehabilitated sits on the upper surface of the seat, the lower limb muscle monitoring components are tied to the two legs, and the feet step on the pedal. By stepping on the pedal to drive the crank to rotate, since the semiconductor pressure sensor is in contact with the sole of the foot, during the process of driving the pedal and the crank to move, the force exerted by the foot on the flywheel inside the frame is monitored by the semiconductor pressure sensor. At the same time, the surface electromyogram electrode patches monitor the leg muscle information and transmit the monitored information to the wireless surface electromyograph. Moreover, the semiconductor pressure sensor also transmits the sole force application data to the wireless surface electromyograph for recording.

[0014] In the technical solution of the above-mentioned rehabilitation training monitoring system for stroke patients, preferably: the cross sections of the U-shaped frames are all U-shaped, and square sleeves are sleeved on the outer surfaces of the U-shaped frames. The top parts of the square sleeves are respectively fixedly connected to the left and right ends of the elastic band.

[0015] In the technical solution of the above-mentioned rehabilitation training monitoring system for stroke patients, preferably: there is a space on the left and right sides of the U-shaped frame and the pedal for the square sleeve to rotate, and the bottom surface of the elastic band contacts the instep through elasticity.

[0016] In the technical solution of the above-mentioned rehabilitation training monitoring system for stroke patients, preferably: openings for embedding and fixing semiconductor pressure sensors are provided on the upper surface of the pedal, and the top sensing surface of the semiconductor pressure sensor is 1-2 cm higher than the top end surface of the pedal.

[0017] In the technical solution of the above-mentioned rehabilitation training monitoring system for stroke patients, preferably: a magic hook tape is sewn on the inner surface of the left section of the binding band, and a magic loop tape is sewn on the outer surface of the right section of the binding band.

[0018] In the technical solution of the above-mentioned rehabilitation training monitoring system for stroke patients, preferably: the front binding band is bound at the position of the calf muscle group, the rear binding band is bound at the position of the thigh muscle group, and the surface electromyogram electrode patches are all in contact with the leg muscles.

[0035] Refer to the attached drawings of the specification Figure 4 As shown: The lower limb muscle monitoring component 2 includes two binding straps 21 respectively tied around the outer circles of the thigh and calf. 2-3 surface electromyogram electrode patches 22 are inlaid on the inner surfaces of the binding straps 21;

[0036] Refer to the attached drawings of the specification Figure 5 As shown: The wireless surface electromyograph 3 includes an electromyogram main unit 31 and an electromyogram signal receiver 32 connected to the signal receiving end of the electromyogram main unit 31 through a wire harness.

[0037] Refer to the attached drawings of the specification Figure 2 As shown: The bottom surface of the vehicle frame 11 is fixedly connected to a vehicle frame base 12 through screws. Support cross bars are fixedly connected to the front and rear ends of the bottom of the vehicle frame base 12. A faucet 15 is fixedly connected to the front side surface of the vehicle frame 11. A display screen 16 is fixedly connected to the top end of the faucet 15. Grips 17 are fixedly connected to the left and right sides of the faucet 15. A support seat 19 is fixedly connected to the rear side of the upper surface of the vehicle frame 11. The top end of the support seat 19 is fixedly connected to the bottom surface of the seat 18 through screws.

[0038] Refer to the attached drawings of the specification Figure 3 As shown: The cross section of the U-shaped frame 110 is U-shaped, and a square sleeve 111 is sleeved on the outer surface of the U-shaped frame 110. The top parts of the square sleeve 111 are respectively fixedly connected to the left and right ends of the elastic band 112; There is a space for the square sleeve 111 to rotate between the U-shaped frame 110 and the left and right sides of the pedal 13. The bottom surface of the elastic band 112 contacts the instep through elasticity; Openings for inlaying and fixing the semiconductor pressure sensor 113 are provided on the upper surface of the pedal 13. The top sensing surface of the semiconductor pressure sensor 113 is 1-2 cm higher than the top end face of the pedal 13.

[0039] Refer to the attached drawings of the specification Figure 4 As shown: A magic male fastener is sewn on the inner surface of the left section of the binding strap 21, and a magic female fastener is sewn on the outer surface of the right section of the binding strap 21; The front binding strap 21 is tied around the position of the calf muscle group, and the rear binding strap 21 is tied around the position of the thigh muscle group. The surface electromyogram electrode patches 22 are all in contact with the leg muscles.

[0040] According to the above-mentioned preferred technical solution content, the working process of this technical solution is described as follows:

[0041] It should be noted that since the surface electromyography electrode patch 22 needs to be adhesively contacted with the leg muscles of the patient to be rehabilitated, it belongs to consumables; after the current patient has used it, the used surface electromyography electrode patch 22 needs to be replaced from the binding strap 21. Therefore, a magic hook surface sticker is sewn in the groove on the inner side of the binding strap 21 for inlaying the surface electromyography electrode patch 22, and a magic loop surface sticker is adhesively attached to the surface of the surface electromyography electrode patch 22 by glue. After use, the magic sticker is torn off to replace the new surface electromyography electrode patch 22.

[0042] The binding strap 21 is successively bound to the calves and thighs of the left and right legs. Depending on the magic stickers on the inner and outer surfaces of the binding strap 21, the binding strap 21 is firmly bound, and several surface electromyography electrode patches 22 on the inner surface of the binding strap 21 are in contact with the muscles of the thighs and calves. When the foot is placed on the pedal 13, the foot is bound by the elasticity of the elastic band 112, and at this time, the sole of the foot is in contact with the semiconductor pressure sensor 113.

[0043] When the person to be rehabilitated sits on the upper surface of the seat 18, the lower limb muscle monitoring member 2 is bound by both legs, and the foot steps on the pedal 13. By stepping on the pedal 13, the crank 14 is driven to rotate. Since the semiconductor pressure sensor 113 is in contact with the sole of the foot, during the process of driving the pedal 13 and the crank 14 to move, the force of the foot driving the flywheel inside the frame 11 is monitored by the semiconductor pressure sensor 113. At the same time, the surface electromyography electrode patch 22 monitors the leg muscle information and transmits the monitored information to the wireless surface electromyograph 3, and the semiconductor pressure sensor 113 also transmits the sole force application data to the wireless surface electromyograph 3 for recording.

[0044] The present invention is not limited to the above-mentioned optimal implementation manner.

Therefore, they do not have technical essence.
