Description

Technical Field

[0001] This utility model relates to the field of physics, and more particularly to a shoulder joint function testing device, especially a wearable device for shoulder joint function testing. Background Technology

[0002] As my country enters an aging society and young people's demand for sports increases, degenerative shoulder joint diseases and sports injuries leading to functional disorders are on the rise, and the number of surgeries is also increasing every year.

[0003] In existing technologies, the methods for assessing the range of motion (rotation angle) and strength of the shoulder joint rely on manual measurement by medical staff using a protractor and an object of a certain weight (such as a weight). Data recording requires manual input, and patients need to come to the hospital to cooperate with medical staff for measurement.

[0004] This measurement method has the following drawbacks:

[0005] First, it is quite cumbersome. Data recording requires manual measurement and registration before being entered into a computer spreadsheet for scoring.

[0006] Second, the measurement error is relatively large each time, and it is affected by many factors (such as the thickness of clothing).

[0007] Third, the records are one-way, with only medical staff measuring the patient. The patient cannot actively report changes in the range of motion and strength of the shoulder joint to the medical staff during the rehabilitation exercise process.

[0008] Fourth, due to the different personnel and tools used in the measurements, it is difficult to generate a large amount of reliable and valid data in shoulder joint measurement and scoring. Summary of the Invention

[0009] The purpose of this invention is to provide a wearing device for shoulder joint function testing, which aims to solve the technical problems of cumbersome and error-prone manual testing in the prior art.

[0010] This utility model discloses a wearable device for shoulder joint function testing, comprising a housing, in which a gyroscope sensor, a thin-film pressure sensor, a controller, and a power supply are disposed. The signal output terminals of the gyroscope sensor and the thin-film pressure sensor are connected to the controller, which is connected to a Bluetooth module. The power supply terminals of the gyroscope sensor, the thin-film pressure sensor, the controller, and the Bluetooth module are connected to the power supply. A pressing plate is disposed on the top of the housing, and the pressing plate is connected to the housing by at least two springs evenly distributed along the circumference. The springs bias the pressing plate upward. A movable column is connected to the lower center of the pressing plate. A through hole is disposed in the top of the housing, and an empty cylinder is fixedly disposed in the through hole. The empty cylinder is positioned above the thin-film pressure sensor. The lower end of the movable column passes downward through the empty cylinder and contacts the sensing part of the thin-film pressure sensor. One end of a wristband is connected to each side of the bottom housing, and a buckle is disposed between the other ends of the two wristbands.

[0011] Furthermore, the housing includes a bottom shell and an upper shell, with the upper shell fixed to the bottom shell by screws and a first screw hole.

[0012] Furthermore, the wristband is connected to the bottom shell via screws and a second screw hole.

[0013] Furthermore, the power source is a rechargeable battery.

[0014] Compared with existing technologies, this invention offers positive and significant advantages. Its compact size makes it portable and easy to use, suitable for measurements in various settings. Patients can actively provide feedback to medical staff on changes in shoulder joint range of motion and strength during rehabilitation exercises. A gyroscope sensor collects the patient's upper limb range of motion, and a thin-film pressure sensor collects upper limb muscle strength values. This data is used by doctors to assess the patient's rehabilitation progress. The data is accurate and reliable, less susceptible to external factors, and reduces errors caused by testing by different individuals. Attached Figure Description

Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0022] like Figures 1-6 As shown, this utility model discloses a wearable device for shoulder joint function testing, comprising a housing 1, in which a gyroscope sensor (not shown), a thin-film pressure sensor 2, a controller (not shown), and a power supply (not shown) are disposed. The signal output terminals of the gyroscope sensor and the thin-film pressure sensor 2 are connected to the controller, which is connected to a Bluetooth module (not shown). The power supply terminals of the gyroscope sensor, the thin-film pressure sensor 2, the controller, and the Bluetooth module are connected to the power supply. A pressing plate 3 is disposed on the top of the housing 1, and the pressing plate 3 is connected to the housing 1 by at least two springs 4. The springs 4 are evenly distributed along the circumference and bias the pressing plate 3 upward. A moving post 5 is connected to the lower center of the pressing plate 3. A through hole is provided in the top of the housing 1, and an empty cylinder 6 is fixedly disposed in the through hole. The empty cylinder 6 is disposed above the thin-film pressure sensor 2. The lower end of the moving post 5 passes downward through the empty cylinder 6 and contacts the sensing part of the thin-film pressure sensor 2. A wristband (not shown) is connected to one end of each side of the bottom shell 8, and a buckle is provided between the other ends of the two wristbands.

[0023] Furthermore, the housing 1 includes a bottom shell 8 and an upper shell 9, with the upper shell 9 fixed to the bottom shell 8 by screws and a first screw hole 10.

[0024] Furthermore, the wristband is connected to the bottom shell 8 via screws and a second screw hole 11.

[0025] Furthermore, the power source is a rechargeable battery.

[0026] Specifically, housing 1 is machined to ensure both precision and strength. Housing 1 is equipped with a battery charging port and a power switch 12. The controller includes an embedded acquisition circuit board and a microcontroller. The microcontroller and gyroscope sensor are mounted on the embedded acquisition circuit board, which is powered by a power supply. A thin-film pressure sensor 2 is fixed to the center of the upper housing 9. A notch is provided at the bottom of the empty cylinder 6 to facilitate the lead wire of the thin-film pressure sensor 2, which is connected to the acquisition circuit board through this notch.

[0027] Specifically, in this embodiment, the gyroscope sensor, thin-film pressure sensor 2, controller, Bluetooth module, power supply, wristband, buckle, rechargeable battery, battery charging port, power switch 12, etc., all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be described in detail here. The software in the controller or mobile phone / computer is not considered an improvement of this utility model.

[0028] The working principle of this embodiment:

[0029] A gyroscope sensor, also known as an angular velocity sensor, can detect the attitude, orientation, and rotation angle of an object in space. A gyroscope sensor is an inertial measurement unit; the direction pointed to by the axis of rotation of a rotating object will not change when not affected by external forces. Based on this characteristic of the rotation axis maintaining its direction, changes in current direction and angle are detected.

[0030] In use, the device is worn on the patient's wrist via a wristband. The power switch 12 is turned on, and the device connects to a mobile phone or computer via Bluetooth. The patient then moves the device around their shoulder joint in movements such as "shoulder raising." A gyroscope sensor collects measurement signals, which are then converted and transmitted via Bluetooth to the mobile phone or computer for data display, providing the patient's upper limb range of motion. Simultaneously, the data is processed, a rehabilitation progress curve is plotted, historical data is saved, and appropriate rehabilitation suggestions are provided. When the patient applies downward force to the pressure plate 3, the pressure plate 3 moves the moving column 5 downward. The hollow cylinder 6 guides the moving column 5, which presses against the thin-film pressure sensor 2. The thin-film pressure sensor 2 collects measurement signals, which are then converted and transmitted via Bluetooth to the mobile phone or computer for data display, providing the arm strength value. Because the pressure plate 3 has weight, pressure initialization can be performed using software before measurement.

[0031] The user interface features simple diagrams illustrating the range of motion, angle, and force of the shoulder joint, allowing both doctors and patients to easily record and analyze data.

[0032] This invention is compact, portable, and easy to use, making it suitable for measurements in various settings. Patients can actively provide feedback to medical staff on changes in shoulder joint range of motion and strength during rehabilitation exercises. A gyroscope sensor collects the patient's upper limb range of motion, and a thin-film pressure sensor 2 collects the patient's upper limb muscle strength values. This data is used by doctors to assess the patient's rehabilitation progress. The data is accurate and reliable, not easily affected by external factors, and reduces errors caused by different testers.
