They have a higher risk of peripheral neuropathy, which often manifests as changes in tactile function in the upper limbs. Therefore, an effective method is needed to evaluate the health status of vibration receptors in parts such as fingers.

[0049] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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 creative work are within the scope of protection of the present invention.

[0050] refer to Figures 1 to 3 , a vibration sense testing device, comprising:

[0051] A test stand, used to support the finger to be tested;

[0052] The physiological characteristic test module is arranged near the finger to be tested and is used to collect changes in physiological parameters caused during the test process;

[0053] The oscillator is fixedly mounted on the test bracket and is used to generate vibration stimuli of different intensities and frequencies;

[0054] A response collection button is used to collect the response signal of the subject and give a response when the subject feels the vibration;

[0055] A control host, used to control the vibration parameters of the oscillator and receive signals from the physiological characteristic test module and the response collection button;

[0056] The host control operation module is connected to the control host and is used to set measurement parameters, receive measurement data and perform calculations to evaluate the vibration intensity that can be felt by the subject's fingers.

[0057] In this embodiment, the finger to be tested is stably supported by the test bracket to ensure stability and accuracy during the measurement process. The physiological characteristic test module can collect the changes in physiological parameters of the subject during the test process in real time. These parameters are crucial for evaluating the overall state of the subject and the sensitivity of vibration perception. The oscillator can generate vibration stimuli of different intensities and frequencies to meet the testing requirements for different vibration perception thresholds. The reaction collection button can accurately capture the reaction signal of the subject to ensure the real-time and accuracy of the measurement results. The host control operation module allows the setting of personalized measurement parameters to meet the needs of different subjects. By collecting and analyzing the physiological parameters and reaction signals of the subject, the vibration intensity that can be felt by the subject's fingers can be comprehensively evaluated, providing strong support for personalized health monitoring and early detection of peripheral neuropathy. The entire test process is automatically controlled by the control host, which reduces the complexity of manual operation and improves test efficiency.

[0058] Preferably, the control host controls the vibration parameters of the oscillator, specifically including:

[0059] The control host generates non-equal amplitude or non-equal frequency vibration parameters according to a preset algorithm, wherein the non-equal amplitude or non-equal frequency vibration parameters present random or pseudo-random changes in vibration intensity, frequency and / or amplitude, so as to simulate complex vibration conditions in a real environment;

[0060] The generated vibration parameters are converted into analog signals through a digital signal processor and sent to the oscillator;

[0061] After receiving the analog signal, the oscillator generates corresponding vibration stimulation to act on the finger being tested.

[0062] In this embodiment, the control host can generate vibration parameters of non-equal amplitude or non-equal frequency, and these parameters show random or pseudo-random changes in vibration intensity, frequency and / or amplitude. This design can more realistically simulate the complex vibration conditions experienced by fingers in actual working environments or daily activities, thereby improving the accuracy and practicality of the test; the generated vibration parameters are converted into analog signals by a digital signal processor (DSP) and sent to the oscillator, which can ensure the accuracy and stability of the vibration stimulation. The high-precision processing capability of the DSP enables the subtle changes in the vibration parameters to be accurately captured and converted, thereby improving the accuracy and reliability of the test; the vibration parameters in this technical solution are adjustable, which means that different vibration parameters can be set according to different test requirements or the specific circumstances of the subjects. This flexibility enables the test device to adapt to a variety of test scenarios and subject groups, improving the adaptability and extensiveness of the test; the vibration parameters are generated by a preset algorithm and automatically sent to the oscillator to generate vibration stimulation, which can greatly simplify the test process, reduce manual intervention and errors, and at the same time, due to the random or pseudo-random changes in the vibration parameters, each test can generate different vibration stimulation, thereby avoiding the deviation of the subjects due to habituation or expected effects, and improving the efficiency and accuracy of the test.

[0063] It should be noted that the control host generates vibration parameters of non-equal amplitude or non-equal frequency according to a preset algorithm, and the specific steps include:

[0064] First, according to the test requirements, the basic range of vibration parameters is set in the control host, including the minimum and maximum values ​​of vibration intensity, the minimum and maximum values ​​of frequency, and the minimum and maximum values ​​of amplitude. These ranges can be flexibly adjusted according to the characteristics of the object being tested (such as body parts, age, gender, etc.) and the purpose of the test (such as health assessment, disease diagnosis, etc.);

[0065] Next, a suitable random or pseudo-random function is selected from the preset algorithm library. This function will be used to generate random or pseudo-random vibration parameters within the parameter range set in step 1. The random function can ensure that the vibration parameters generated each time are different, thereby simulating the complex vibration conditions in the real environment; while the pseudo-random function can maintain a certain regularity and repeatability while ensuring a certain randomness, which is convenient for subsequent data analysis and processing;

[0066] Using the selected random or pseudo-random function, a set of vibration parameters is generated within the set parameter range. This set of parameters may include vibration intensity, frequency, and amplitude, etc., depending on the test requirements. The generated vibration parameters should be able to fully reflect the vibration characteristics in the real environment while ensuring the safety and comfort of the test;

[0067] After generating the vibration parameters, it is necessary to adjust and optimize the parameters according to actual needs. For example, the vibration intensity, frequency, amplitude and other parameters can be fine-tuned according to the feedback and test results of the tested object to ensure the accuracy and reliability of the test results. In addition, the generated vibration parameters can be further screened and classified according to the test purpose and data analysis requirements.

[0068] Finally, the generated vibration parameters are converted into analog signals through a digital signal processor and sent to the oscillator. After receiving the analog signal, the oscillator will vibrate according to the set vibration parameters, thereby realizing the vibration perception test of the object under test.

[0069] Preferably, the control host receives the signal from the physiological characteristic test module and the reaction collection button, specifically including:

[0070] Using quantum key distribution technology, a key distribution channel is established between the physiological characteristic test module, the reaction collection button and the control host, and a random key pair is distributed to the physiological characteristic test module, the reaction collection button and the control host through the key distribution channel;

[0071] After collecting the physiological parameter data, the physiological characteristic test module encrypts the data according to the random key pair. At the same time, when the reaction collection button detects the reaction of the subject, it encrypts the reaction signal according to the random key pair.

[0072] The encrypted data and response signals are transmitted to the control host through the communication channel;

[0073] The control host uses the random key pair to decrypt the received encrypted data and restore the original physiological parameter data and response signal.

[0074] In this embodiment, the quantum key distribution technology is used to ensure that the data transmitted between the physiological characteristic test module, the reaction collection button and the control host has extremely high confidentiality. Since quantum key distribution is based on the principles of quantum mechanics, it can detect any potential eavesdropping behavior, thereby ensuring the security of the data transmission process; the data and reaction signals are encrypted by random key pairs, and even if the data is intercepted during the transmission process, the attacker cannot decrypt or tamper with the data, which ensures the authenticity and integrity of the physiological parameter data and reaction signals received by the control host; the encryption and decryption process is completed by the control host, the physiological characteristic test module and the reaction collection button, ensuring the accuracy and reliability of data transmission, which helps to reduce misjudgments or missed judgments caused by data transmission errors or interference, thereby improving the accuracy and reliability of the entire vibration perception test device; during the vibration perception test process, the subject's physiological parameter data and reaction signals are sensitive. By introducing quantum key distribution technology, it can be ensured that these data will not be leaked to unauthorized third parties during the transmission process, thereby protecting the privacy rights and interests of the subjects.

[0075] Preferably, the host control operation module receives the measurement data and performs calculation processing to evaluate the vibration intensity that can be felt by the subject's fingers, specifically including:

[0076] Receiving measurement data from the control host, including vibration intensity, vibration frequency, amplitude, physiological characteristics of the subject, and response signals of the subject;

[0077] According to the changes in the subject's physiological parameters during the measurement process, the weight coefficient W of each parameter is calculated. i ;

[0078] The physiological parameters are weighted using the weight coefficients to obtain the comprehensive physiological characteristic parameter U;

[0079] Count the vibration intensity V that the subjects can feel in multiple measurements x The distribution of

[0080] According to the comprehensive physiological characteristic parameters U of the subjects, the vibration intensity V x Make corrections;

[0081] The corrected data were used to assess the vibration perception threshold of the subjects.

[0082] In this embodiment, by receiving multiple measurement data from the control host, including vibration intensity, vibration frequency, amplitude, and physiological characteristics and reaction signals of the subject, the technical solution ensures the comprehensiveness and accuracy of the data, and these data provide a solid foundation for subsequent weighted processing and threshold evaluation; according to the changes in the physiological parameters of the subject during the measurement process, the weight coefficients of each parameter are calculated, and the physiological parameters are weighted using these weight coefficients to obtain comprehensive physiological characteristic parameters. This step fully considers the individual differences of the subjects, making the evaluation results more personalized and accurate; by statistically analyzing the distribution of vibration intensity that the subject can feel in multiple measurements, the technical solution can more accurately reflect the vibration perception threshold of the subject, and at the same time, the vibration intensity is corrected according to the comprehensive physiological characteristic parameters of the subject, further improving the accuracy of the evaluation; the vibration perception threshold of the subject is evaluated using the corrected data. The technical solution not only improves the efficiency of the evaluation, but also ensures the reliability of the evaluation results, which helps doctors or researchers to more accurately judge the health status of the subject's finger blood vessels and provide strong support for subsequent diagnosis and treatment or research.

[0083] Preferably, the physiological parameters are weighted by using weighting coefficients to obtain a comprehensive physiological characteristic parameter U, and the specific calculation formula is as follows:

[0084]

[0085] Among them, U represents the comprehensive physiological characteristic parameter, f ij represents the evaluation grade of the i-th factor on solution j, W i represents the weight coefficient of the i-th factor, and n represents the number of measurements.

[0086] Preferably, the vibration intensity V that the statistical subject can feel in multiple measurements is x The specific calculation formula is as follows:

[0087] V x =∑(V i )*U;

[0088] Among them, V x Represents the vibration intensity, V i Represents the average vibration intensity of i from 1 to n.

[0089] Preferably, the physiological characteristic testing module includes a heart rate monitor, a respiration monitor and a skin conductance sensor.

[0090] In this embodiment, physiological parameters such as heart rate, respiration and skin conductance can reflect the stress response and activity of the autonomic nervous system of the subject when receiving vibration stimulation. Real-time monitoring and recording of these parameters can help to more accurately evaluate the subject's perception and tolerance to vibration; the physiological characteristics test module covers multiple physiological parameters and can reflect the subject's physiological state from different angles. This multi-dimensional data collection method makes the evaluation results more comprehensive and helps to discover potential health problems or abnormal reactions; everyone's physiological reactions are different. By real-time monitoring of the subject's heart rate, respiration, skin conductance and other parameters, personalized evaluations can be performed based on the individual's physiological characteristics. This personalized evaluation method can more accurately reflect the subject's actual vibration perception and health status.
