Description

Technical Field

[0001] The present invention belongs to the technical field of rehabilitation medicine and intelligent education technology, and specifically is a simulation arm model based on muscle tension assessment. Background Art

[0002] The simulated arm model for muscle tone assessment is used for standardized and precise assessment and teaching of upper limb dystonia, assisting rehabilitation medicine teaching, clinical skills training and dystonia diagnosis;

[0003] Currently, traditional simulated arm models for muscle tone assessment are commonly used teaching tools. When the teacher logs into the teacher management platform and triggers the corresponding operation, the entire system, like a precision instrument awakened, instantly enters an orderly operating mode. Upon receiving the operation signal, a series of internal components begin to work together in an orderly manner. At this time, a specific motor is precisely activated and driven. This motor acts as a power engine, rapidly rotating the connected elbow joint accordingly, simulating the changes in muscle tone in a real arm. As the elbow rotates, relevant muscle tone data is transmitted to the display in real time and clearly displayed on the screen. Intuitive curves are automatically generated, allowing teachers and students to intuitively understand the dynamic changes in muscle tone.

[0004] However, in actual teaching, when the monitor displays muscle tension data and graphs, students often flock to it, attempting to observe, perceive, and record the assessment results. However, due to the large number of students and limited display space, many students are unable to clearly see the content on the monitor immediately, making it even more difficult to accurately record key data. This can lead to some students missing important assessment information due to untimely or incomplete observation, reducing the overall teaching effectiveness. Summary of the Invention

[0013] Preferably, it also includes:

[0014] The sealing component is arranged at the top end of the liquid outlet pipe surface. The sealing component comprises a liquid inlet fixedly connected to the top end of the liquid outlet pipe surface. The top end of the liquid inlet surface is sleeved with a sealing plug.

[0015] Preferably, a guide shell is fixedly installed inside the connecting block, and the guide shell is of conical design.

[0019] Preferably, one side of the top of the connecting block is designed as a slope, and the extrusion block 1 and the extrusion block 2 are both designed as spherical.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention drives the rotating plate and the squeezing block to rotate during the rotation of the elbow joint. The squeezing block squeezes and pushes the connecting block. When the connecting block moves, the elastic member is stretched. Then the connecting block pushes the squeezing plate to slide inside the liquid outlet pipe.

[0022] The present invention starts to rotate at the elbow joint, driving the electric push rod and the extrusion block 2 connected thereto to rotate synchronously. During the rotation process, the motor 4 is driven to adjust the extrusion block 2 to a vertical state with the display board. At the same time, the electric push rod is driven so that its output shaft pushes the extrusion block 2 to make close contact with the air bag on the surface of the display board. Subsequently, the extrusion block 2 moves smoothly along the surface of the display board, continuously squeezing the air bag, thereby clearly leaving the motion track of the elbow joint. The present invention finally links the electric push rod with the elbow joint to make the extrusion block 2 squeeze the air bag, leaving the motion track of the elbow joint, making it easy to judge whether the elbow joint is offset during rotation, timely discovering and adjusting problems, and effectively improving the accuracy of the muscle tension level.

[0023] The present invention drives the connecting rod to move when the extrusion plate is reset, thereby pulling the sealing plate to slide inside the circular tube. The sealing plate moves toward the surface, squeezing the air inside the circular tube. The air passes through the second one-way valve and the air intake hose and flows into the interior of the display board, which makes the airbag on the surface of the display board full and inflated again, making full preparations for the next muscle tension level assessment, thereby greatly improving the efficiency and consistency of the assessment work.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the present invention provides a simulated arm model based on muscle tension assessment, including a main body 1, a motor 1 2, a motor 2 3, a shoulder joint 4, an elbow joint 5, a motor 3 6 and a motor 4 7, and further comprising:

[0034] The visualization mechanism 8 is arranged on one side of the outer surface of the shoulder joint 4. The visualization mechanism 8 includes a rotating plate 801 fixedly connected to one side of the elbow joint 5. An extrusion block 802 located on the outer surface of the shoulder joint 4 is fixedly installed on one side of the rotating plate 801. An elastic member 803 is fixedly installed on one side of the outer surface of the shoulder joint 4. One end of the elastic member 803 is fixedly installed with a connecting block 804 located on one side of the extrusion block 802. An extrusion plate 807 is fixedly installed on one side of the connecting block 804. A liquid outlet pipe 805 is slidingly sleeved on the surface of the extrusion plate 807. A scale 806 is fixedly installed on one side of the liquid outlet pipe 805, and the scale 806 is communicated with the liquid outlet pipe 805.

[0035] The above solution is adopted: the teacher logs in to the teacher management platform. When the teacher triggers the operation and the system receives the operation signal, it is like a precision instrument being started, and a series of internal components begin to operate in an orderly manner. At this time, one of the motor 1 2, motor 2 3, motor 3 6 and motor 4 7 will be accurately driven. This driven component is like the starting end of a chain, which quickly drives the shoulder joint 4 and the elbow joint 5 to rotate accordingly. In the process of the elbow joint 5 rotating, it will drive the rotating plate 801 to rotate, and the rotating plate 801 will drive the extrusion block 1 802 to rotate. In the process of the extrusion block 1 802 rotating, it will squeeze and push the connecting block 804. When the connecting block 804 moves, the elastic member 803 will be stretched, and then the connecting block 804 will push the squeezing plate 807 to slide inside the liquid outlet tube 805. Since the scale 806 is connected to the liquid outlet tube 805, the liquid inside the liquid outlet tube 805 will be pushed into the scale 806 during the sliding process. Then, the muscle tension level can be judged according to the distance the liquid flows. Finally, the elbow joint 5 causes the rotating plate 801 to drive the squeezing plate 807 to push the liquid into the scale 806. The distance the liquid flows can be used to judge the muscle tension level, thereby facilitating students to intuitively observe and feel and record the assessment results, thereby improving the teaching effect.

[0036] In addition, motor 1 2 is connected to the shoulder joint gear through a synchronous belt to control the abduction of the shoulder joint, motor 2 3 is connected to the elbow joint 5 through a synchronous belt to control the flexion and extension of the elbow joint 5, motor 3 6 is connected to the wrist joint through a synchronous belt to control the flexion and extension of the wrist joint, and motor 4 7 is connected to the wrist joint to control the pronation and supination of the wrist joint.

[0037] like Figure 2 、 Figure 4 and Figure 6 As shown, it also includes:

[0038] The trajectory display mechanism 9 is arranged on one side of the shoulder joint 4. The trajectory display mechanism 9 includes a display board 901 fixedly connected to the bottom end of the main body 1. An air outlet pipe 902 is fixedly installed on one side of the display board 901. A one-way valve 1 903 is provided inside the air outlet pipe 902. An electric push rod 904 is fixedly installed at the bottom end of the elbow joint 5, and an extrusion block 2 905 is fixedly installed at the output end of the electric push rod 904.

[0039] With the above solution, through the design of the trajectory display mechanism 9, when the elbow joint 5 starts to rotate, the electric push rod 904 and the second extrusion block 905 connected thereto are driven to rotate synchronously. During the rotation process, the motor 4 7 is driven to adjust the second extrusion block 905 to a perpendicular state with respect to the display board 901. At the same time, the electric push rod 904 is driven so that its output shaft pushes the second extrusion block 905 to closely contact the airbag on the surface of the display board 901.

[0040] Subsequently, the squeezing block 2 905 moves smoothly along the surface of the display board 901, continuously squeezing the airbag. As the squeezing degree deepens, the air pressure inside the display board 901 increases sharply. The strong pressure pushes open the one-way valve 1 903, allowing the air inside the display board 901 to be smoothly discharged from the one-way valve 1 903 and the inside of the air outlet pipe 902. The unique design prevents the squeezed airbag from resetting on its own, thereby clearly leaving the movement trajectory of the elbow joint 5. Finally, the elbow joint 5 is linked to the electric push rod 904 to make the squeezing block 2 905 squeeze the airbag, leaving the movement trajectory of the elbow joint 5, making it easy to judge whether the elbow joint 5 is offset during rotation, and to detect and adjust problems in time, thereby effectively improving the accuracy of the muscle tension level.

[0041] like Figure 3 and Figure 5 As shown, a protective shell 12 is fixedly installed on the outer surface of the shoulder joint 4, the liquid outlet pipe 805 is fixedly connected to the protective shell 12, and a square hole is opened at the top of the protective shell 12.

[0042] The above solution is adopted: through the design of the protective shell 12, since the protective shell 12 is arranged on the surface of the visualization mechanism 8, the visualization mechanism 8 can be protected and its service life can be improved, and the liquid outlet pipe 805 is fixedly connected to the protective shell 12, thereby ensuring that the extrusion plate 807 can slide stably inside the liquid outlet pipe 805.

[0043] like Figure 5 、 Figure 6 and Figure 7 As shown, it also includes:

[0044] The inflatable component 10 is arranged at the top of the protective shell 12. The inflatable component 10 includes a circular tube 1001 fixedly connected to the top of the protective shell 12. A one-way valve 1002 is provided inside the circular tube 1001. The inside of the circular tube 1001 is slidably connected to a sealing plate 1003 located on one side of the one-way valve 1002. A connecting rod 1004 is fixedly installed on one side of the sealing plate 1003. One end of the connecting rod 1004 is fixedly connected to the extrusion plate 807, and the connecting rod 1004 can slide inside the square groove. An air intake hose 1005 is fixedly installed on the top of the outer surface of the circular tube 1001, and one end of the air intake hose 1005 is fixedly connected to the display board 901.

[0045] The above solution is adopted: through the design of the inflation component 10, when the muscle tension level assessment is completed and the elbow joint 5 starts the reset process, the extrusion block 1 802 slowly moves away from the surface of the connecting block 804, and the elastic member 803 that was stretched previously will pull the connecting block 804 and the extrusion plate 807 back to its original position. When the extrusion plate 807 is reset, it drives the connecting rod 1004 to move, and then pulls the sealing plate 1003 to slide inside the circular tube 1001. The sealing plate 1003 moves toward the surface of the one-way valve 2 1002, squeezing the air inside the circular tube 1001. The strong air pressure pushes open the one-way valve 2 1002, and the air passes through the one-way valve 2 1002 and the air intake hose 1005 and flows into the interior of the display board 901, which makes the airbag on the surface of the display board 901 full and inflated again, making full preparations for the next muscle tension level assessment, greatly improving the efficiency and consistency of the assessment work.

[0046] like Figure 5 As shown, it also includes:

[0047] The sealing component 11 is arranged at the top of the surface of the liquid outlet pipe 805. The sealing component 11 includes a liquid inlet 1101 fixedly connected to the top of the surface of the liquid outlet pipe 805. The top of the surface of the liquid inlet 1101 is provided with a sealing plug 1102.

[0048] Adopting the above solution: through the design of the sealing component 11, the liquid can be injected into the liquid outlet pipe 805 from the liquid inlet 1101. After the liquid injection is completed, the sealing plug 1102 can be put on the surface of the liquid inlet 1101, and the sealing plug 1102 will enter the interior of the liquid inlet 1101, thereby ensuring the sealing of the liquid outlet pipe 805.

[0049] like Figure 5 As shown, the guide shell 13 is fixedly installed inside the connecting block 804, and the guide shell 13 is a conical design, the extrusion plate 807 is a circular design, and the surface of the extrusion plate 807 fits the inner wall of the liquid outlet pipe 805, and the display board 901 is made of transparent material, and the display board 901 is designed.

[0050] The above solution is adopted: through the design of the guide shell 13, since the guide shell 13 is a conical design, when the extrusion plate 807 moves, the guide shell 13 can guide the liquid into the inside of the scale 806. Through the design of the extrusion plate 807, since the extrusion plate 807 is a circular design, it can be ensured that the extrusion plate 807 can move smoothly inside the liquid outlet pipe 805, and the surface of the extrusion plate 807 fits with the inner wall of the liquid outlet pipe 805, thereby ensuring the sealing of the liquid outlet pipe 805 and preventing the liquid from flowing out from the gap between the extrusion plate 807 and the liquid outlet pipe 805. Through the design of the display board 901, since the display board 901 is made of a transparent material, it is convenient for students sitting on the side of the main body 1 to observe the muscle tension level through the display board 901, thereby improving the teaching effect.

[0051] like Figure 4 and Figure 5 As shown, a telescopic rod is provided inside the elastic member 803, and both ends of the telescopic rod are fixedly connected to the shoulder joint 4 and the connecting block 804. One side of the top of the connecting block 804 is designed as a slope, and the extrusion block 1 802 and the extrusion block 2 905 are both spherical designs.

[0052] The above solution is adopted: through the design of the elastic member 803, since a telescopic rod is provided inside the elastic member 803, when the elastic member 803 is stretched, the telescopic rod will extend, and then it can support the connecting block 804 and limit the elastic member 803. Through the design of the connecting block 804, since one side of the top of the connecting block 804 is a sloped design, and the extrusion block 1 802 and the extrusion block 2 905 are both spherical designs, the friction between the connecting block 804 and the extrusion block 1 802 can be reduced, which makes it convenient for the extrusion block 1 802 to push the connecting block 804 to move stably, and the surface of the extrusion block 2 905 is smooth, so when the airbag is squeezed, the airbag can be protected and the service life of the airbag is increased.

[0053] The working principle and use process of the present invention:

[0054] First, the teacher logs in to the teacher management platform. When the teacher triggers the operation and the system receives the operation signal, it is like a precision instrument being started, and a series of internal components begin to operate in an orderly manner. At this time, one of the motor 1 2, motor 2 3, motor 3 6 and motor 4 7 will be driven accurately, and the driven component will drive the shoulder joint 4 and elbow joint 5 to rotate accordingly. In the process of the elbow joint 5 rotating, the rotating plate 801 and the squeezing block 1 802 will be driven to rotate. The squeezing block 1 802 will squeeze and push the connecting block 804. When the connecting block 804 moves, the elastic member 803 will be stretched, and then the connecting block 804 will push the squeezing plate 807 to slide inside the liquid outlet tube 805. Then the squeezing plate 807 will push the liquid inside the liquid outlet tube 805 to the inside of the scale 806. Then, the muscle tension level can be judged according to the distance the liquid flows.

[0055] When the elbow joint 5 starts to rotate, it drives the connected electric push rod 904 and the second extrusion block 905 to rotate synchronously. During the rotation process, the motor 4 7 is driven to adjust the second extrusion block 905 to a perpendicular position with the display board 901. At the same time, the electric push rod 904 is driven so that its output shaft pushes the second extrusion block 905 to make close contact with the airbag on the surface of the display board 901. Subsequently, the second extrusion block 905 moves smoothly along the surface of the display board 901, continuously squeezing the airbag. As the airbag is squeezed, the air inside the display board 901 is smoothly discharged from the inside of the one-way valve 1 903 and the exhaust pipe 902. The unique design prevents the squeezed airbag from resetting on its own, thus clearly leaving the movement trajectory of the elbow joint 5.

[0056] After the muscle tension level assessment is completed and the elbow joint 5 starts the reset process, the squeezing block 1 802 slowly moves away from the surface of the connecting block 804. The elastic member 803 that was stretched previously will pull the connecting block 804 and the squeezing plate 807 back to their original positions. When the squeezing plate 807 is reset, it drives the connecting rod 1004 to move, thereby pulling the sealing plate 1003 to slide inside the circular tube 1001. The sealing plate 1003 moves toward the surface of the one-way valve 2 1002, squeezing the air inside the circular tube 1001. The air passes through the one-way valve 2 1002 and the air intake hose 1005 and flows into the interior of the display board 901, which makes the airbag on the surface of the display board 901 full and inflated again, making full preparations for the next muscle tension level assessment, and finally completing the operation process.
