[0029] See also Figure 1 - Figure 6In the present embodiment, an airbag pressure device for musculoskeletal assessment is involved, which is specifically used to simulate different muscle and bone load conditions through multi-point pressure to evaluate and train the user's musculoskeletal function. Specifically comprising: a frame 1, a base 11 is arranged below the frame 1, a hip support module 2 is fixed above the base 11, two support rods 13 are symmetrically arranged on both sides of the hip support module 2, a table 14 is fixed on the upper end of the support rod 13, a hand pressure airbag 3 is arranged at the front end of the table 14, an arm pressure airbag 4 is arranged at the rear end of the table 14 close to the hip support module 2, a leg pressure airbag 5 is arranged at the lower end of the support rod 13, and the base 11 is also symmetrically arranged with two groups of foot pressure airbags 6 on the front side of the hip support module 2, a top support 12 is arranged above the frame 1, and two groups of shoulder pressure airbags 7 are symmetrically arranged on the top support 12;

[0030] The hip support module 2 includes a seat cushion 21, a seat rod 26 is fixed below the seat cushion 21, and the seat rod 26 is fixed on the base 11;

[0031] A telescopic component 123 is connected above the shoulder pressure airbag 7 to drive the pressure component to move up and down;

[0032] The inner wall surfaces of the cavities of the hand pressure airbag 3, the arm pressure airbag 4, the leg pressure airbag 5, the foot pressure airbag 6 and the shoulder pressure airbag 7 are all provided with raised ribs. After the airbags are inflated, the raised ribs expand accordingly. Pressure feedback is applied to various parts of the patient through the airbags and the raised ribs in their cavities, simulating the dynamic process of human muscles and bones under load conditions. A hard cover structure is provided on the outside of the airbags, so that the airbags are more conducive to occupying the internal space of the cover after inflation, so as to achieve a better pressure effect and facilitate the doctor's evaluation.

[0033] Specifically, in this embodiment, in the preparation stage: under the guidance of a doctor, the patient's buttocks are supported by the seat cushion 21 and the seat rod 26, so that the patient maintains a sitting state on the base 11 through the buttocks support module 2. Evaluation stage:

[0034] According to the different parts of the musculoskeletal assessment, multiple groups of airbags are provided to act on different parts of the human body. Among them, the hand pressure airbag 3 is used to apply pressure to the muscles and bones in the patient's hand area. During the assessment, the patient's palm needs to be inserted into the cavity of the hand pressure airbag 3. The hand pressure airbag 3 presses the patient's palm after being inflated. The doctor can adjust the patient's gesture (make a fist, or only insert fingers into the cavity of the hand pressure airbag 3) according to the patient's fracture situation to provide personalized musculoskeletal assessment operation.

[0035] The arm pressure airbag 4 and the leg pressure airbag 5 both adopt a bellows structure, and the length and size can be adjusted according to the different clinical diagnosis parts, and can adapt to the limb sizes of different patients. For example, the arm pressure airbag 4 can apply pressure to the muscles and bones of the upper arm, forearm and elbow joint respectively, while the leg pressure airbag 5 can apply pressure to the muscles and bones of the thigh, calf and knee joint respectively.

[0036] The foot pressure airbag 6 exerts pressure on the foot. The sole of the patient's foot is inserted into the foot pressure airbag 6, and the foot pressure airbag 6 exerts pressure on the sole of the foot after being inflated.

[0037] The shoulder pressure airbag 7 is located above the patient in the initial state. The telescopic component 123 of this embodiment adopts a cylinder to achieve the lifting effect of the shoulder pressure airbag 7. Under the guidance of the doctor, the patient stands on the base 11 of the frame 1 with both feet. At the same time, under the action of the telescopic component 123, the shoulder pressure airbag 7 descends and contacts the patient's shoulders, and the patient remains in a standing state. The shoulder pressure airbag 7 continues to press down, applying a load to the patient's shoulders, which is suitable for overall pressure on the patient's trunk muscles and bones.

[0038] The patient switches from standing to sitting: the patient's buttocks are supported by the buttocks support module 2, so that the patient's upper body is placed between the shoulder pressure airbag 7 and the buttocks support module 2, and the shoulder pressure airbag 7 continues to press downward through the telescopic component 123, applying pressure to the patient's upper body, simulating the pressure that the shoulders may bear in daily life or work.

[0039] By simulating the load conditions of different muscles and bones, this device can provide users with a more accurate assessment of their musculoskeletal status, and also provide more diverse solutions for rehabilitation training. It helps to improve rehabilitation efficiency, speed up the patient's recovery process, and ultimately improve the patient's quality of life. In addition, the personalized adjustment function of this device ensures that it can adapt to the physical conditions of different users, making rehabilitation training more humane. Through the above various evaluation methods, the musculoskeletal evaluation airbag pressure device of this embodiment can not only provide doctors with detailed information about the patient's musculoskeletal status, but also provide patients with necessary support and treatment during rehabilitation training. It is particularly suitable for patients who need rehabilitation training after shoulder surgery or injury, and athletes who need to conduct muscle strength and endurance assessments.

[0040] The hip support module 2 also includes a lifting component 25 for driving the seat cushion 21 to rise and fall and a moving component 111 for driving the seat cushion 21 to move forward and backward. The lifting component 25 is arranged between the seat cushion 21 and the seat rod 26, and the moving component 111 is arranged at the connection between the seat rod 26 and the base 11. The lifting component 25 in this embodiment adopts a corrugated airbag, which expands after being inflated to raise the height of the seat cushion 21, and contracts after being deflated to reduce the height of the seat cushion 21. By adjusting the height of the seat cushion 21 by the lifting component 25, it can adapt to users of different heights, ensuring that the user's feet can comfortably touch the surface of the base 11 during musculoskeletal assessment and maintain a correct sitting posture. This adjustment mechanism not only improves the scope of use of the equipment, but also helps to reduce the additional musculoskeletal burden caused by improper sitting posture, thereby improving the accuracy of the assessment and the effect of rehabilitation training. In addition, the moving component 111 in this embodiment adopts a screw motor, which is engaged with a slider through a screw thread, and the slider is fixed to the seat rod 26 through a threaded fastener 8 above the slider to achieve the forward and backward movement of the seat cushion 21. The forward and backward movement function of the cushion 21 allows the user to adjust the position of the cushion 21 according to the individual's body proportions and rehabilitation needs, further enhancing the personalized rehabilitation experience. At the same time, when the patient is in a standing state, the hip support module 2 is moved to the rear side by the moving component 111 to reduce the space occupied by the base 11. This design makes the entire device more compact and facilitates musculoskeletal assessment in a limited space.

[0041] The hip support module 2 also includes a backrest 22, which is fixed to the rear end of the seat cushion 21, and a headrest 24 is connected to the top of the backrest 22. The backrest 22 and the headrest 24 are provided to improve the comfort of the patient during the pressure operation. For example, when pressure is applied to the patient's shoulders while sitting, the backrest 22 provides a stable support for the patient's back, so that the patient maintains a good sitting posture. The head is supported by the headrest 24, which is telescopically adjustable. The height of the headrest 24 can be adjusted by manually pulling it out to meet the height and head support requirements of different users, so that the device can better adapt to various users and alleviate the discomfort caused by the pressure process.

[0042] The front side of the backrest 22 is provided with a flexible lumbar support 23, and the backrest 22 is provided with a plurality of groups of telescopic airbags 221 on the back of the flexible lumbar support 23. The telescopic airbags 221 are arranged in a square array, and extend into the cavity of the flexible lumbar support 23 and contact the inner wall surface of the flexible lumbar support 23. The square array arrangement of the telescopic airbags 221 allows the airbags to expand independently, and can apply targeted pressure to the muscles and bones in the injured area of ​​the patient's waist, provide customized support for the patient's waist, and adjust according to the user's body shape and sitting posture needs, thereby providing a more comfortable and ergonomic experience.

[0043] The backrest 22 is also fixed with an adjustable waist belt 27, which is also provided with a buckle 271. The length of the waist belt 27 is adjusted by the buckle 271 to adjust the tightness of the patient. The waist belt 27 and the waist support 23 form a closed loop structure. When performing musculoskeletal assessment, the waist belt 27 can be adjusted according to the patient's body shape and the required support level to ensure that the patient maintains a correct sitting posture when using the device, which is convenient for doctors to conduct inspections and assessments.

[0044] The arm pressure airbag 4 and the leg pressure airbag 5 are both provided with a connecting rod 15, and the connecting rod 15 is hinged on the support rod 13. The hinge structure facilitates the adjustment of the arm pressure airbag 4 and the leg pressure airbag 5 at different angles to adapt to the body shape and specific rehabilitation needs of different users.

[0045] The support rod 13 is an electric telescopic rod, the table 14 is fixed to the movable section 131 at the upper end of the support rod 13, and the leg pressure airbag 5 is fixed to the fixed section 132 at the lower end of the support. The movable section 131 can be extended up and down to adjust the height of the table 14 to meet the different hand placement heights of different patients in a normal sitting state, thereby increasing the application range of the device.

[0046] The foot pressure airbag 6 is fixed on the pedal 61 of the base 11, and the pedal 61 is provided with a rebound mechanism 62. The rebound mechanism 62 can provide instant feedback force after foot pressure is applied, increase the dynamics of the musculoskeletal function of the patient's ankle during training, and is suitable for musculoskeletal evaluation of the ankle.

[0047] The top bearing 12 is provided with a double-axis motor 121, and the driving shaft of the double-axis motor 121 is connected and adapted to the telescopic component 123 through a screw 122. The screws 122 connected at both ends of the double-axis motor 121 are arranged in opposite directions, and the screw 122 is meshed and adapted with the telescopic component 123 (the end cover of the cylinder) through the thread structure. When the double-axis motor 121 rotates, the telescopic component 123 synchronously moves toward or relative to the screw 122 (realized by the forward and reverse rotation of the double-axis motor 121), which is suitable for shoulder pressure operation of patients with different shoulder widths.

[0048] A connecting portion 71 is provided above the shoulder pressure airbag 7, and the connecting portion 71 is connected to the telescopic component 123 through a threaded fastener 8. The threaded fastener 8 is used to facilitate the disassembly and replacement of the shoulder pressure airbag 7, and the shoulder pressure airbag 7 of different specifications can be replaced according to the patient's body shape, so that the shoulder pressure airbag 7 fits the patient's shoulder better.
