Technical Field

[0001] This utility model belongs to the field of elbow joint training technology, and in particular relates to an elbow joint training device with a spasticity detection function. Background Technology

[0002] The elbow joint is an important joint of the upper limb, connecting the upper arm and forearm, and playing a role in support, flexion and rotation. Elbow joint training devices are used to help patients restore, strengthen or improve elbow joint function, especially after injury, surgery or long-term inactivity.

[0003] Existing elbow joint training devices lack spasticity detection capabilities, which means that muscle spasms during use cannot be detected in time, potentially leading to further injury. Furthermore, the devices lack adjustable restraint mechanisms, preventing them from being adjusted to fit different arm sizes for proper fixation. Therefore, we provide an elbow joint training device with spasticity detection to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an elbow joint training device with a spasticity detection function. By combining the detection component and the tightening component, it solves the problem that existing elbow joint training devices do not have spasticity detection and restraint adjustment functions during use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0012] The present invention is further configured such that a through groove is provided on one side of the restraint ring, and the restraint strap is in contact with the restraint ring.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model uses a flexible pressure sensor to monitor pressure changes in the patient's upper and lower arms in real time, enabling timely detection of muscle spasms and preventing secondary injuries caused by spasms during training. This significantly improves training safety. The combination of a restraint strap, buckle, and limiting ring allows for flexible adjustment of tightness according to the patient's arm size, ensuring the device is securely fixed and comfortable, adapting to the needs of patients of different body types.

Detailed Implementation

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model is an elbow joint training device with spasticity detection function, including an upper arm guard plate 1, and a forearm guard plate 2 provided on the rear side of the upper arm guard plate 1. The upper arm guard plate 1 and the forearm guard plate 2 are used for patient protection during training. Each of the upper arm guard plate 1 and the forearm guard plate 2 is provided with a restraint ring 3 at the top, which is used to fix the patient's upper arm and forearm. The restraint ring 3 is provided with a detection component, which includes a first Velcro 8 installed inside the restraint ring 3 and a flexible pressure detection sensor 4 fixedly connected to one side of the first Velcro 8. The flexible pressure detection sensor 4 can detect the pressure at the patient's upper arm and forearm in real time. It is a mature existing technology and will not be described in detail here. The top of the restraint ring 3 is provided with a tightening component, which includes a restraint strap 5 fixedly connected to one side of the restraint ring 3 and a buckle 6 fixedly connected to the outer surface of the restraint ring 3.

[0026] Example 2

[0027] Please see Figures 1-4Based on Embodiment 1, the detection component further includes a mounting groove 7 on one side of the restraint ring 3, a second Velcro 9 fixedly connected inside the mounting groove 7, and a flexible pressure detection sensor 4 installed and fixed in the mounting groove 7 via a first Velcro 8 and a second Velcro 9, which can be quickly replaced. The tightening component also includes a limiting groove 10 on the top of the restraint strap 5, and a limiting ring 11 fixedly connected to the outer surface of the restraint ring 3. One side of the restraint strap 5 can be inserted into the limiting ring 11 to prevent it from detaching from the buckle 6. A connecting plate 12 is fixedly connected to the bottom of the restraint ring 3. The upper arm guard plate 1 and the lower arm guard plate 2 are fixedly connected to the connecting plate 12. A horizontal plate 13 is fixedly connected to one side. A display screen 14 and an alarm 15 are fixedly connected to the top of the horizontal plate 13. A microcontroller is fixedly connected to the top of the horizontal plate 13. The data detected by the flexible pressure sensor 4 is transmitted to the microcontroller. After processing, the microcontroller can display the data on the display screen 14. The microcontroller, display screen 14 and alarm 15 are all existing mature technologies, and will not be described in detail here. A connecting frame 16 is fixedly connected to one side of the upper arm guard plate 1, and a movable frame 17 is fixedly connected to one side of the lower arm guard plate 2. The connecting frame 16 and the movable frame 17 are movably connected by a rotating shaft. A through groove 18 is opened on one side of the restraint ring 3, and the restraint strap 5 is in contact with the restraint ring 3.

[0028] The working principle of this invention is as follows: The patient places their upper arm and forearm into the corresponding restraint rings 3, and pulls the restraint straps 5 according to the limb's thickness. The tightness is fixed by the buckles 6 and the limiting rings 11, ensuring that the device fits the limb closely and is not easily loosened. During training, the flexible pressure detection sensor 4 continuously monitors changes in limb pressure, and the data is transmitted to the microcontroller in real time. If abnormal pressure is detected, such as a sudden increase, it indicates that muscle spasm may occur.

[0029] The microcontroller displays the processed data on the screen 14 for user observation. Once the pressure exceeds a preset threshold, the alarm 15 is immediately triggered to warn the patient to stop training and avoid injury. The patient performs rehabilitation exercises by flexing and extending the elbow joint. The upper arm guard 1 and forearm guard 2 provide physical protection, while the pivot design of the connecting frame 16 and the movable frame 17 ensures smooth movement. Simultaneously, the stable fixation of the restraint ring 3 prevents displacement during training. By integrating spasticity detection, adjustable restraint, and real-time alarm functions, the safety and compatibility issues of traditional elbow joint training devices are solved, significantly improving the efficiency and safety of rehabilitation training, especially suitable for postoperative or sports injury rehabilitation.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
