[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] To facilitate understanding of this embodiment, the application scenarios and design concepts of this application embodiment will be briefly introduced below.

[0033] In detecting Parkinson's disease, parameters such as hand tremors and finger pinching force can aid in diagnosis. Hand tremors can be measured using accelerometers, while finger pinching force can be assessed using pressure sensors. These sensors capture dynamic changes in hand movements, providing crucial data for diagnosis.

[0034] This product operates on the principle of monitoring and recording hand movements using sensors on a wearable device, based on the pathological characteristics of Parkinson's disease. Specifically, a piezoelectric sensor detects the frequency and amplitude of tremors, a piezoresistive sensor measures the force applied by the fingers, and an accelerometer and gyroscope are used to verify the tremors detected by the piezoelectric sensor. By analyzing this data, typical symptoms of Parkinson's disease, such as resting tremor and bradykinesia, can be identified.

[0035] The system processes sensor data using algorithms to extract key features, such as tremor frequency, movement speed, and changes in force. These features are closely related to the clinical symptoms of Parkinson's disease and can be used to aid in diagnosis. For example, resting tremor typically manifests as rhythmic movement at 4-6 Hz, while bradykinesia in Parkinson's patients can be identified by a decrease in movement speed.

[0036] Ultimately, through continuous monitoring and data analysis, the system can provide doctors with quantitative diagnostic information, helping them better understand and assess the progression of Parkinson's disease. This sensor-based monitoring method provides an effective tool for the early diagnosis and long-term management of Parkinson's disease.

[0037] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0038] like Figures 1 to 4 The Parkinson's disease motion monitoring device provided in this embodiment includes a pen body 100, acupressure component 200, tremor detection component 300, and control component 400.

[0039] The pen body 100 includes a pen body assembly 110 and a pen tip 120. The pen body assembly 110 has a mounting portion, and the pen tip 120 is located at one end of the pen body assembly 110. A finger pressure component 200 is located at the end of the pen body assembly 110 near the pen tip 120. The finger pressure component 200 includes a sensing portion surrounding its outer side, which is used to press with a finger and measure the pressure applied by the finger. A vibration detection component 300 is located at the mounting portion and is used to detect vibration of the pen body. A control component 400 is located at the mounting portion and is electrically connected to both the finger pressure component 200 and the vibration detection component 300. The control component 400 includes a power supply 410.

[0040] Specifically, the Parkinson's disease motion monitoring device provided in this embodiment has a pen-like structure, making it small in size and easy to carry and move. During use, detection can be achieved through writing, making the process very convenient.

[0041] During the writing process, the movement trajectory, speed, and writing force of the pen tip 120 can be recorded. The finger pressure component 200 can measure the force applied by the fingers, and the tremor detection component 300 can detect the tremor frequency. By collecting the changes in writing trajectory and speed, fingertip force, and tremor frequency, the data are sent to the control component 400 for comprehensive analysis to assess motor function and help identify the presence of symptoms of Parkinson's disease.

[0042] Furthermore, the control component 400 can incorporate data from other sensors, such as surface electromyography (sEMG) sensors, to further enhance diagnostic accuracy. By comprehensively analyzing data from multiple sensors, a more holistic assessment of the patient's motor function can be achieved, thereby improving the reliability of Parkinson's disease detection.

[0043] In this embodiment, the vibration detection assembly 300 includes a detection element 310 and a limiting element 320. The mounting part includes a mounting groove 111. There are multiple detection elements 310, all of which are disposed in the mounting groove 111 and are arranged at an angle to each other. The limiting element 320 is detachably disposed in the opening of the mounting groove 111 to press the multiple detection elements 310 into the mounting groove 111.

[0044] The detection element 310 is installed in the mounting slot 111. When writing with the Parkinson's disease motion monitoring device, the detection element 310 can measure the tremor frequency of the pen body assembly 110 to detect the tremor frequency of the user's hand.

[0045] The limiting member 320 is installed over the opening of the mounting groove 111. The limiting member 320 and the mounting groove 111 together press the detection member 310, thereby limiting the detection member 310 and preventing the detection member 310 from shaking too much in the mounting groove 111 due to excessive installation gap, which would lead to errors in the detection results.

[0046] Furthermore, the multiple detection elements 310 are arranged at an angle, enabling accurate detection of vibrations in multiple directions, resulting in more comprehensive vibration detection. This layout avoids the situation where a single detection element 310 cannot detect vibrations in various directions.

[0047] In this embodiment, a plurality of fixing parts are provided in the mounting groove 111. One end of the detection element 310 is a fixed end, and the other end is provided with a counterweight 311. The fixed ends of the plurality of detection elements 310 are respectively disposed in the plurality of fixing parts. The limiting element 320 includes a plurality of clamping parts, which are inserted into the fixing parts to clamp the fixed ends.

[0048] Specifically, in this embodiment, one side of the fixed end of the detection element 310 is attached to and abuts against the fixed part, the limiting member 320 is inserted into the fixed part, and the limiting member 320 is attached to the other side of the fixed end to press the fixed end, thereby fixing the detection element 310.

[0049] In this embodiment, the detection element 310 is specifically a piezoelectric sensor. Piezoelectric sensors are characterized by high sensitivity, high signal-to-noise ratio, and wide bandwidth response. They are also simple in structure, small in size, lightweight, and have excellent reliability and stability.

[0050] Because piezoelectric sensors are lightweight, they are prone to failing to detect vibrations of low intensity. In this embodiment, a counterweight 311, specifically a metal block, is provided at the end of the piezoelectric sensor furthest from the fixed end. The metal block is attached to one end of the piezoelectric sensor by adhesive, increasing the weight at that end. When subjected to vibration, the metal block amplifies the vibration intensity, causing the fixed end of the piezoelectric sensor to vibrate as well, thus preventing the inaccurate detection of small vibrations due to the sensor's light weight.

[0051] In this embodiment, the fixing part is a V-groove. The clamping part is a wedge-shaped insert that fits the V-groove.

[0052] See Figure 3 In this embodiment, the wedge-shaped insert can be inserted into the V-groove, thereby clamping the sheet-like piezoelectric sensor from both sides together with the V-groove, thus fixing the piezoelectric sensor.

[0053] Furthermore, to ensure that the limiting member 320 and the V-groove can clamp the piezoelectric sensor, the limiting member 320 in this embodiment is provided with a through hole, and the V-groove is provided with a screw hole communicating with the through hole. After the limiting member 320 is placed on the V-groove, the limiting member 320 can be locked onto the V-groove with screws to ensure the connection strength between the limiting member 320 and the V-groove, thereby ensuring the installation strength of each piezoelectric sensor and preventing the piezoelectric sensor from becoming loose.

[0054] In this embodiment, there are three detection elements 310. The detection directions of the three detection elements 310 are perpendicular to each other, and the three detection elements 310 form a three-dimensional detection coordinate system to achieve full-angle detection.

[0055] Please refer to it again. Figure 3 In this embodiment, the three piezoelectric sensors are arranged perpendicularly to each other, forming a three-dimensional space with mutually perpendicular X, Y, and Z axes, thereby achieving accurate collection and detection of vibrations.

[0056] In this embodiment, the finger pressure assembly 200 includes a piezoresistive sensor 210. The piezoresistive sensor 210 is disposed along the circumference of the pen body 100.

[0057] Specifically, the piezoresistive sensor 210 in this embodiment is a piezoresistive pressure sensor. Piezoresistive pressure sensors have the characteristics of high sensitivity, high resolution, high accuracy and high stability. At the same time, they are small in size, light in weight, fast in response, highly adaptable, have a small temperature coefficient and a high natural frequency, making them very suitable for use in portable devices.

[0058] In this embodiment, there are three piezoresistive sensors 210. The three piezoresistive sensors 210 are arranged around the pen body 100 and connected to form a triangular prism structure.

[0059] See Figure 2 In this embodiment, three piezoresistive sensors 210 are arranged together to form a triangular prism with a cross-section that provides excellent stability. The triangular prism design is also well-suited to the pressure applied by the user's fingers while writing. Each of the three piezoresistive sensors 210 can individually measure the pressure applied by one of the three fingers.

[0060] In this embodiment, the control component 400 includes a power supply 410 and a control element 420. The power supply 410 and the control element 420 are electrically connected and are spaced apart in the mounting portion.

[0061] Specifically, in this embodiment, the control component 420 is a circuit board, and the power supply 410 is a lithium battery.

[0062] Specifically, the circuit board is a PCBA circuit board. In this embodiment, the piezoresistive sensor 210 and the detection element 310 are both connected to the circuit board via cables, so that the signals of each sensor can be transmitted to the circuit board, and the lithium battery can also power each sensor.

[0063] Furthermore, in addition to collecting sensor data, the circuit board in this embodiment also integrates an accelerometer and a gyroscope, which can be used for secondary verification of the vibrations detected by the piezoelectric sensor and provide more data parameters.

[0064] In addition, the circuit board in this embodiment also has Bluetooth communication and power management functions. The Bluetooth communication function is used to transmit the collected sensor data to the host computer, and the power management function ensures normal power supply to the circuit board and provides the ability to charge the power supply 410 when a power cord or data cable is connected.

[0065] In this embodiment, the pen tip 120 includes a capacitive pen tip 121 and a copper post 122. The capacitive pen tip 121 is disposed at the end of the pen tip 120, and the copper post 122 is inserted into the pen body assembly 110 and connected to the capacitive pen tip 121.

[0066] The capacitive pen tip 121 can be used with devices equipped with capacitive screens and corresponding software to achieve accurate detection and recording of writing trajectories.

[0067] In this embodiment, the pen body assembly 110 includes a main body and a cover. The mounting portion is disposed within the main body. The cover is detachably disposed on the main body to close the mounting portion.

[0068] The main body can accommodate and house the power supply 410, circuit board and detection component 310, and the cover can seal the mounting part, thereby ensuring that each component can be safely and stably stored inside the main body.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
