Description

Technical Field

[0001] The present invention relates to the technical field of brain disease limb rehabilitation, and in particular to an intelligent rehabilitation training device for brain and limb diseases. Background Art

[0002] There are many rehabilitation equipment for brain diseases, and the neurosurgery rehabilitation centers of various hospitals also have many rehabilitation equipment. For general cerebral infarction diseases, hospitals let patients combine active and passive exercises. Active exercise is to let them do sitting exercises, and patients use targeted rehabilitation training equipment for exercise. Passive exercise mainly includes acupuncture massage, medium frequency therapeutic instrument transcranial magnetic stimulation, etc.

[0003] Among them, the ankle is an important joint of the human body. In order to make the ankle joint recover to a normal state better, appropriate rehabilitation training of the ankle is required. Since the ankle is located on the lower side of the human body and bears the overall weight of the person, it is impossible to stand and walk for rehabilitation after injury, so auxiliary equipment is needed for rehabilitation training; the ankle rehabilitation training device with the prior art publication number CN210019574U drives two cams to rotate through a motor, thereby causing the pedal to tilt forward and backward, helping patients with ligament injuries to recover their ligaments.

[0004] However, the above device cannot formulate corresponding rehabilitation training methods according to the actual situation of the patient, because when different patients recover to different states, the strength of their ankle force is also different. If suitable rehabilitation training equipment is not formulated, the effect of the patient's ankle rehabilitation training will be greatly reduced; for this reason, the present application proposes an intelligent rehabilitation training device for brain and limb diseases. Summary of the invention

[0005] The purpose of the present invention is to solve the above technical problems and to propose an intelligent rehabilitation training device for brain and limb diseases.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An ankle rehabilitation training mechanism used in conjunction with a testing mechanism; the ankle rehabilitation training mechanism includes a pedal rotatably mounted on a mounting box, a foot limiting belt being fixed to the pedal, and the testing mechanism can control the resistance of the pedal when it is driven by the movement of the patient's foot according to the values ​​measured by the first pressure sensor and the second pressure sensor.

[0010] Preferably, two T-shaped guide rails are fixedly connected to the upper end of the support platform, a T-shaped sliding sleeve is sleeved on the T-shaped guide rail, and seats are fixed on the two T-shaped sliding sleeves.

[0011] Preferably, a fixed plate is fixed on the support platform, a movable plate is fixed on the two T-shaped sliding sleeves, a sleeve is fixed on the fixed plate, the second pressure sensor is fixed in the sleeve, a connecting piece abutting against the first pressure sensor is fixed on the first pressure sensor, a driving rod is fixed on the movable plate, a sliding block sliding in the sleeve is fixed on the driving rod, a first spring is fixed on the sliding block, and the first spring is fixedly connected to the connecting piece.

[0012] Preferably, an electric slide rail is embedded and installed on the base, an electric slider is installed on the electric slide rail, and the electric slider is fixedly connected to the support platform.

[0013] Preferably, two support blocks are fixed on the installation box, a short shaft is fixed on the support block, and the pedal is rotatably mounted on the short shaft.

[0014] Preferably, a liquid box is installed in the installation box, and an arc-shaped tube fixedly connected to the upper side wall of the installation box is penetrated by a side wall, and a piston is slidably connected in the arc-shaped tube, and an arc-shaped rod is fixed on the piston, and the other end of the arc-shaped rod is rotatably connected to the bottom of the pedal, and a delivery pipe is fixed to the other end of the arc-shaped tube, and the delivery pipe penetrates the liquid box and is fixedly connected to it, and an annular electromagnet fixedly connected to the delivery pipe is sleeved on the delivery pipe, and a limiting flow ring is fixedly connected to the bottom of the delivery pipe, and a flow-limiting ring is sleeved on the outside of the flow-limiting ring, and a plurality of fluid holes are penetrated by the bottom of the flow-limiting ring, and a magnetic ring is fixed on the upper end of the flow-limiting tube, and the magnetic poles of the opposite surfaces of the magnetic ring and the annular electromagnet are opposite, and a second spring is fixed on the magnetic ring, and the other end of the second spring is fixedly connected to the annular electromagnet.

[0015] Preferably, the arc-shaped rod and the arc-shaped tube are located on the same circumference, and the center of the circumference where the arc-shaped rod and the arc-shaped tube are located coincides with the axis of the minor axis.

[0016] Preferably, it also includes a control system, which is connected to the first pressure sensor, the second pressure sensor, the electric slide rail, and the annular electromagnet.

[0017] Preferably, a plug post of different lengths opposite to the fluid hole is connected to the bottom of the flow limiting ring, and the plug post is arranged in cooperation with the fluid hole.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The first pressure sensor can be used to detect changes in the strength of the patient's legs. The second pressure sensor can detect the pressure generated by the two feet. Due to the different strengths of the ankles, the two second pressure sensors detect different pressures, which facilitates subsequent rehabilitation training for the feet to different degrees.

[0020] 2. The values ​​detected by the first pressure sensor and the second pressure sensor are transmitted to the control system. The control system performs calculations based on the numerical results and energizes the annular electromagnet to control the flow cross-sectional area of ​​the fluid, thereby controlling the driving force when the pedal is driven.

[0021] 3. When the fluid hole is partially blocked, the cross-section of the fluid outflow is reduced, so that the pressure on the patient to drive the pedal to rotate will increase. Since the pressure applied by the foot is large, the angle pressure of driving the pedal to rotate during rehabilitation training will also increase; on the contrary, when the patient's foot moves back and resists the foot limit belt, it will drive the pedal to reverse and the required power will also increase; the pedal is repeatedly driven to rotate, so targeted rehabilitation training can be carried out on the ankle that can exert force, and the rehabilitation training effect is better.

[0022] 4. When the current flowing through the annular electromagnet is small, the fluid hole is not large enough to be blocked by the current limiting ring. At this time, the cross-sectional area of ​​the fluid outflow remains unchanged, so the resistance to the repeated rotation of the driving pedal also becomes smaller. This is a targeted training for the feet with less force.

[0023] 5. Setting the plugs of different lengths can cooperate with the movement of the choke tube and block the fluid hole to different degrees, thereby increasing the resistance accuracy of the fluid passing through the fluid hole, and then improving the accuracy of the force applied to drive the pedal to rotate, so as to provide more targeted rehabilitation training for the patient's ankle and improve the effect of rehabilitation training.

[0024] To sum up, the present invention detects the degree of force exerted by the patient's foot through a testing mechanism, thereby controlling the area of ​​the fluid flowing through the fluid hole, and further controlling the resistance when the pedal is driven to rotate. It can accurately perform rehabilitation training on the patient's ankle, improve the effect of rehabilitation training, and avoid some unnecessary rehabilitation training.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1

[0036] Reference Figure 1-Figure 7 An intelligent rehabilitation training device for brain and limb diseases includes a base 1, a mounting box 2 is installed on the base 1, and a bracket 3 is installed on the mounting box 2; wherein two handles 5 are fixed on the upper end of the bracket 3 so that the patient can hold it to exert force.

[0037] Testing mechanism; The testing mechanism includes a support platform 7 movably mounted on a base 1, wherein an electric slide rail 16 is embedded and mounted on the base 1, an electric slider is mounted on the electric slide rail 16, the electric slider is fixedly connected to the support platform 7, the direction in which the electric slider moves on the electric slide rail is perpendicular to the direction in which the T-shaped slide sleeve 9 moves on the T-shaped guide rail 8, and the movement of the electric slider can drive the support platform 7 to move so as to adjust the position of the patient's foot so as to place it on the pedal 17.

[0038] A seat 6 is slidably connected to the support platform 7, and two T-shaped guide rails 8 are fixedly connected to the upper end of the support platform 7. A T-shaped sliding sleeve 9 is sleeved on the T-shaped guide rail 8, and the seat 6 is fixed on the two T-shaped sliding sleeves 9, so that the stable movement of the seat 6 can be ensured; a sponge pad and a sponge backrest are installed on the seat 6 to increase the comfort of the patient when using it.

[0039] A first pressure sensor 24 is installed between the seat 6 and the support platform 7, a fixed plate 10 is fixed on the support platform 7, a movable plate 11 is fixed on two T-shaped sliding sleeves 9, a sleeve 12 is fixed on the fixed plate 10, the first pressure sensor 24 is fixed in the sleeve 12, a connecting piece 25 abutting against the first pressure sensor 24 is fixed, a driving rod 13 is fixed on the movable plate 11, a slider 22 sliding in the sleeve 12 is fixed on the driving rod 13, a first spring 23 is fixed on the slider 22, and the first spring 23 is fixedly connected to the connecting piece 25.

[0040] The installation box 2 is provided with two placement grooves 14, in which two second pressure sensors 15 are fixed. When the patient's feet are placed in the placement grooves 14 and the patient stretches his legs, the seat 6 can be driven to move and generate pressure on the first pressure sensor 24. The pressure applied by the patient's feet can be detected by the two second pressure sensors 15.

[0041] An ankle rehabilitation training mechanism used in conjunction with a testing mechanism; the ankle rehabilitation training mechanism includes a pedal 17 rotatably mounted on a mounting box 2, two support blocks are fixed on the mounting box 2, a short shaft is fixed on the support block, and the pedal 17 is rotatably mounted on the short shaft; a foot limiting belt 18 is fixed on the pedal 17, and the testing mechanism can control the resistance of the pedal 17 when it is driven by the movement of the patient's foot according to the values ​​measured by the first pressure sensor 24 and the second pressure sensor 15.

[0042] Among them, a liquid box 21 is installed in the installation box 2, and the liquid box 21 can contain fluids such as clean water; an arc tube 20 fixedly connected to the upper side wall of the installation box 2 is penetrated, a piston 26 is slidably connected in the arc tube 20, and an arc rod 19 is fixed on the piston 26, the arc rod 19 and the arc tube 20 are on the same circumference, and the center of the circle where the arc rod 19 and the arc tube 20 are located coincides with the axis of the short axis.

[0043] The other end of the arc rod 19 is rotatably connected to the bottom of the pedal 17, and the other end of the arc tube 20 is fixed with a delivery pipe 27, which passes through the liquid tank 21 and is fixedly connected thereto. The delivery pipe 27 is sleeved with an annular electromagnet 29 fixedly connected thereto, and the bottom of the delivery pipe 27 is fixedly connected to a limiting ring 31, and the outer part of the limiting ring 31 is sleeved with a choke tube 28, and the bottom of the choke tube 28 is penetrated by a plurality of fluid holes 32, and the upper end of the choke tube 28 is fixed with a magnetic ring, and the magnetic ring and the annular electromagnet 29 have opposite magnetic poles on opposite sides, and a second spring 30 is fixed on the magnetic ring, and the other end of the second spring 30 is fixedly connected to the annular electromagnet 29.

[0044] Among them, it also includes a control system 4, which is connected to the first pressure sensor 24, the second pressure sensor 15, the electric slide rail 16, and the annular electromagnet 29. The control system 4 includes a central processing unit, a computing module, a storage module, a control module, a detection module, and a transmission module. The control module and the transmission module are connected to the central processing unit, the first pressure sensor 24, the second pressure sensor 15, the electric slide rail 16, and the annular electromagnet 29. The storage module is connected to the central processing unit for storing data. The computing module is connected to the central processing unit and can calculate the values ​​detected by the first pressure sensor 24 and the second pressure sensor 15 for comprehensive calculation. Two data are obtained, corresponding to the left and right ankles respectively; the detection module is connected to the electric slide rail 16 for detecting the position of the electric slide rail 16.

[0045] When the present invention is used, the patient sits on the seat 6, and then places both feet in the two placement grooves 14 and against the second pressure sensor 15, and then the patient's legs are stretched out, so that the seat 6 and the T-shaped sliding sleeve 9 can be driven to move, and the movement of the T-shaped sliding sleeve 9 drives the movement of the moving plate 11, and the movement of the moving plate 11 drives the driving rod 13 and drives the slider 22 to move, and the slider 22 moves to squeeze the first spring 23, and the first spring 23 applies pressure to the connecting piece 25 and acts on the first pressure sensor 24, and the force change of the patient's legs can be known through the first pressure sensor 24;

[0046] Among them, this strength is when the patient's legs are stretched out and exerting force in a comfortable state. At this time, the ankle will change in angle but the ankle will not feel pain. The doctor can communicate with the patient to confirm. It is not a test of the maximum strength.

[0047] At the same time, the second pressure sensor 15 can detect the pressure generated by the two feet. Due to the different strengths of the ankles, the pressures detected by the two second pressure sensors 15 are different.

[0048] As mentioned above, the values ​​detected by the first pressure sensor 24 and the second pressure sensor 15 are transmitted to the control system 4, and the control system 4 performs calculations based on the results of the values, and energizes the annular electromagnet 29 (the pressures detected by the two second pressure sensors 15 are different, and the currents supplied to the annular electromagnet 29 are also different, the larger the pressure, the larger the current, and the smaller the current). Since the magnetic poles of the annular electromagnet 29 and the opposite surface of the magnetic ring are opposite, when the annular electromagnet 29 is energized, an attraction is generated between the annular electromagnet 29 and the magnetic ring, and this attraction can drive the magnetic ring and the choke tube 28 to move, and at this time the second spring 30 is compressed;

[0049] The electric slider slides on the electric slide rail 16 to drive the support platform 7 to move. Figure 2 As shown, if the support platform 7 moves to the left, the right ankle is subjected to rehabilitation training, and vice versa, the left ankle is subjected to rehabilitation training;

[0050] The patient places his feet on the pedal 17 and holds the handle 5 with both hands. The pedal 17 rotates to drive the arc rod 19 to move. The movement of the arc rod 19 drives the piston 26 to move. The movement of the piston 26 can squeeze the fluid in the arc tube 20 into the flow blocking cylinder 28, and finally discharge it through the fluid hole 32.

[0051] If the current flowing through the annular electromagnet 29 is large, the attraction between the annular electromagnet 29 and the magnetic ring will also increase, which will cause the choke tube 28 to move upward, thereby compressing the space between the limiting ring 31 and the fluid hole 32. Finally, the choke tube 28 and the limiting ring 31 will abut against each other, and the fluid hole 32 will be partially blocked.

[0052] When the fluid hole 32 is partially blocked, the cross section of the fluid outflow is reduced, so that the pressure of the patient driving the pedal 17 to rotate will increase. Since the pressure applied by the foot is large, the angle pressure of driving the pedal 17 to rotate during rehabilitation training will also increase; on the contrary, when the patient's foot moves back and contacts the foot limit belt 18, the pedal 17 will be driven to reverse, and the required power will also increase; the pedal 17 is repeatedly driven to rotate, so that targeted rehabilitation training can be performed on the ankle that can exert force, and the rehabilitation training effect is better;

[0053] When the current flowing through the annular electromagnet 29 is small, the fluid hole 32 is not large enough to be blocked by the current limiting ring 31. At this time, the cross-sectional area of ​​the fluid outflow remains unchanged, so the resistance to the repeated rotation of the driving pedal 17 also becomes smaller, thereby providing targeted training for the feet with less force.

[0054] Example 2

[0055] Reference Figure 8 The difference between this embodiment and the first embodiment is that the bottom of the flow limiting ring 31 in this embodiment is connected with a plug 33 of different lengths opposite to the fluid hole 32, and the plug 33 is arranged in coordination with the fluid hole 32;

[0056] Since the pressures applied by the two feet are different, the distances moved by the choke tube 28 are also different. The plug posts 33 of different lengths can cooperate with the movement of the choke tube 28 and block the fluid hole 32 to different degrees, thereby increasing the resistance accuracy of the fluid passing through the fluid hole 32, and further improving the accuracy of the force applied to drive the pedal 17 to rotate, thereby enabling more targeted rehabilitation training for the patient's ankle and improving the effect of rehabilitation training.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
