Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a fistula blood vessel protection device used for nephrology nursing. Background Art

[0002] Arteriovenous fistula is a common vascular access for patients in nephrology. It requires a surgical operation on the arm to directly anastomose the artery and vein together to form a channel for high-pressure blood to flow directly into the vein. This vascular access can promote venous dilation, increase wall thickness, and increase blood flow, eventually forming a venous vessel similar to an artery, providing stable blood flow for hemodialysis, so that the blood flow of the arteriovenous fistula is not less than 180-200ml / min. However, various problems may occur in the long-term use of fistula vessels, such as weakened tremor, thrombosis, redness, swelling and pain at the puncture site, serpentine swelling, and even the formation of hemangiomas. If these problems are not discovered and treated in time, they may have a serious impact on the patient's health and even affect the patient's lifeline (fistula vessels).

[0003] Daily self-checking of whether the fistula blood vessels are unobstructed is one of the daily care that patients must perform. Usually, patients need to gently touch the skin on the side of the fistula with their fingers to feel whether there is a "cat-like" tremor. If there is, it means that the fistula is unobstructed; if the tremor weakens or cannot be felt, the puncture site is red and swollen, or even the fistula suddenly hurts, these are signs that there may be problems with the fistula blood vessels, and patients should seek medical attention in time. Although this method is simple and easy, it has the problems of strong subjectivity and low accuracy, and it is impossible to monitor changes in the fistula blood vessels in real time.

[0004] Moreover, in the actual nursing process, due to various factors such as patient activity, improper tightness of the protective shell, inaccurate monitoring, etc., the fistula blood vessels are easily damaged or abnormal. Traditional fistula blood vessel protection devices often have single functions and lack the ability of real-time monitoring and intelligent adjustment, which makes it difficult to meet the needs of modern nephrology care.

[0005] In order to solve the above problems and improve the protective effect of fistula blood vessels, the present invention proposes a fistula blood vessel protection device based on renal internal medicine care, which aims to realize real-time monitoring and automatic adjustment of fistula blood vessels by integrating multiple sensors and intelligent adjustment mechanisms, thereby improving the patient's comfort and nursing efficiency, avoiding missing the important time window for recanalization of fistula blood vessels, and also increasing the utilization rate of fistula blood vessels. Summary of the invention

[0006] To solve the above problems, the present invention provides a fistula blood vessel protection device for nephrology care, which is used to monitor the status of the fistula blood vessels in real time and automatically adjust the tightness of the protective shell, thereby improving the patient's comfort and care efficiency to avoid missing the important time window for recanalization of the fistula blood vessels.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a fistula blood vessel protection device based on renal internal medicine nursing, comprising a protective shell, the protective shell is an arc-shaped structure, a monitoring component for monitoring fistula blood vessel tremor and an adjusting component for adjusting the tightness of the protective shell are installed on the protective shell, the adjusting component comprises a power member, the output shaft of the power member is fixedly connected to the adjusting rod, a plurality of adjusting belts are fixedly connected to the adjusting rod, the other end of the adjusting belt passes through the protective shell and is fixedly connected to the side wall of the protective shell, the length of the adjusting belt is greater than the circumference of the protective shell, the monitoring component is fixedly connected to the moving component, an installation chamber is provided inside the protective shell, a through groove is provided on the side wall of the installation chamber, and a first rack is fixedly connected to the side walls on both sides of the through groove, the moving component comprises a driving member, the output shaft of the driving member is coaxially fixedly connected to a rotating wheel, the rotating wheel is a gear structure, the rotating wheel is meshed with the first rack, and the monitoring component is installed on the side of the rotating wheel away from the driving member;

[0008] The monitoring component includes a vibration sensor for monitoring the tremor of the fistula blood vessels, a pressure sensor for monitoring the protective strength of the protective shell on the patient's arm, an angle sensor and an acceleration sensor for monitoring the patient's daily activities. The power component signal is connected to the controller, and the vibration sensor, pressure sensor, angle sensor, acceleration sensor and driving component are all connected to the controller signal:

[0009] When the vibration sensor detects that the tremor of the fistula blood vessels does not match the threshold in the controller, and the angle sensor and acceleration sensor do not detect the patient's daily activities, it means that the fistula blood vessels are abnormal, and the controller reminds the patient to seek medical treatment;

[0010] When the vibration sensor detects that the tremor of the fistula blood vessels does not match the threshold in the controller, and the angle sensor and the acceleration sensor detect that the patient is performing daily activities, it means that the abnormality of the fistula blood vessels may be caused by daily activities. The controller reminds the patient to stop the ongoing daily activities, and the vibration sensor re-monitors the vibration of the fistula blood vessels;

[0011] When the vibration sensor cannot detect the tremor data of the internal fistula blood vessel, and the monitoring data of the pressure sensor does not change, it means that the monitoring component is displaced, and the controller starts the driving component to drive the moving component through the driving component, thereby resetting the monitoring component;

[0012] When the vibration sensor cannot detect the vibration data of the internal fistula blood vessel, and the monitoring data of the pressure sensor does not match the threshold value in the controller, it means that the protective shell is loose, and the control starts the power part to adjust the elastic band of the protective shell.

[0013] The technical principle of the above scheme is as follows: the vibration sensor is used to monitor the vibration of the fistula blood vessels in real time and transmit the monitoring data to the controller. The pressure sensor monitors the pressure of the protective shell on the patient's arm to ensure that the protection is moderate and not too tight or too loose. The angle sensor and acceleration sensor are used to monitor the patient's daily activities, such as the movement angle and acceleration of the arm, to distinguish whether the abnormal vibration of the fistula blood vessels is caused by daily activities.

[0014] The power member drives the adjustment rod through the output shaft, thereby pulling or loosening the adjustment belt to adjust the tightness of the protective shell. The driving member drives the rotating wheel (gear structure), which meshes with the first rack to realize the movement of the monitoring component in the installation chamber so as to reset the monitoring component when it is displaced.

[0015] The controller receives the monitoring data from each sensor, processes and analyzes it, and issues corresponding reminders or adjustment instructions based on preset thresholds and logical judgments. It controls the start and stop of the power and drive components, and adjusts the tightness of the protective shell and resets the monitoring components.

[0016] The above scheme has the following beneficial effects:

[0017] 1. This solution integrates multiple sensors to monitor the vibration of the fistula blood vessels, the pressure of the protective shell, and the daily activities of the patient in real time. It can monitor the status of the fistula blood vessels more accurately and capture abnormal signals in time, thereby effectively distinguishing whether the abnormal vibration of the fistula blood vessels is caused by daily activities, providing doctors with accurate basis for disease assessment, avoiding misdiagnosis and misjudgment, and helping doctors to formulate more reasonable treatment plans. At the same time, through real-time monitoring, it can also avoid missing the important time window for the recanalization of the fistula blood vessels, and gain precious treatment time for patients. Compared with traditional protection devices, this real-time monitoring and intelligent analysis capability improves the accuracy and timeliness of disease assessment and reduces the potential risks caused by missing the recanalization time. At the same time, it protects the fistula blood vessels in the forearm, so that the fistula blood vessels will not become serpentine and swollen, or even hemangiomas will occur.

[0018] 2. This solution automatically adjusts the tightness of the protective shell according to the monitoring data of the pressure sensor to ensure the comfort of the patient when wearing it. Traditional protective devices often require patients to manually adjust the tightness, and cannot automatically reset the monitoring component, which may cause the patient to feel uncomfortable during wearing or inaccurate monitoring data. The automatic adjustment function of the present invention can avoid problems such as the feeling of arm pressure caused by a protective shell that is too tight, or poor protection due to being too loose, thereby improving the patient's wearing experience and satisfaction. In addition, when the monitoring component is displaced, the present invention can automatically reset to ensure the accuracy and stability of the monitoring data and avoid misdiagnosis or missed diagnosis due to changes in the monitoring position.

[0019] 3. The controller in this solution can automatically analyze the monitoring data and issue corresponding reminders or adjustment instructions based on the analysis results, which greatly reduces the workload of medical staff. Medical staff do not need to pay attention to the patient's monitoring data at all times, they only need to deal with it in time after receiving the reminder. In addition, this intelligent monitoring and management method can also help improve the overall service level and patient satisfaction of the hospital. In contrast, traditional protection devices lack such intelligent and remote monitoring capabilities. Medical staff need to spend more time and energy to manually check and adjust the patient's protection device, and it is difficult to obtain the patient's health status information in a timely manner.

[0020] Furthermore, a fan heat assembly is installed on the inner side wall of the protective shell, and the fan heat assembly includes a plurality of rotating shafts, a plurality of fan blades are fixedly connected to the rotating shafts, and both ends of the rotating shafts are respectively rotatably matched with the side walls on both sides of the installation chamber, and the end of the adjusting rod away from the power part is coaxially fixedly connected with a main gear, and the main gear is meshed with a second rack, and the second rack is slidingly matched with the side wall of the installation chamber. The side wall of the installation chamber close to the skin is a mesh structure, and transmission gears are coaxially fixedly connected to the rotating shafts, and the transmission gears are meshed with the second rack.

[0021] Beneficial effects: The addition of the fan heat component significantly improves the heat dissipation efficiency of the device. The wind flow is generated by the rotating fan blades, which can directly contact the patient's skin and be discharged from the installation chamber through the side walls of the mesh structure, thereby effectively reducing the temperature inside the protective shell and reducing the patient's feeling of stuffiness caused by wearing it for a long time. The improvement in heat dissipation efficiency means that patients can maintain a more comfortable body temperature when wearing the device. This helps to reduce the psychological pressure and discomfort of patients and improve their acceptance and compliance. Since the fan heat component is connected to the adjustment component through gear transmission, the speed of the fan blades and the wind flow intensity can be intelligently adjusted as needed. For example, when the patient's activity level increases or the ambient temperature rises, the speed of the fan blades can be automatically increased to improve the heat dissipation efficiency.

[0022] Furthermore, the monitoring component also includes a temperature sensor, which is used to monitor the temperature inside the protective shell in real time. The temperature sensor is connected to the controller signal. When the temperature monitored by the temperature sensor is too high, the controller starts the power part in the adjustment component to loosen the protective shell. At the same time, the adjustment rod in the adjustment component drives the heat fan component to dissipate heat.

[0023] Beneficial effects: The addition of temperature sensors provides multiple heat dissipation guarantees for the device. When the temperature is too high, it can not only trigger the adjustment component to loosen the protective shell to reduce the internal pressure, but also start the fan component to dissipate heat at the same time. This dual heat dissipation mechanism ensures the stability and safety of the device under extreme conditions. Excessive temperature may cause discomfort or even harm to patients. Through real-time monitoring and intelligent adjustment, the temperature sensor can ensure that the temperature inside the protective shell is always kept within a safe and comfortable range, thereby improving the patient's wearing experience and comfort. The addition of temperature sensors further enhances the intelligence level of the device. Through the signal connection and linkage mechanism with the controller, it can realize intelligent monitoring and adjustment of the temperature inside the protective shell, providing medical staff with more comprehensive and accurate patient health data.

[0024] Furthermore, the angle sensor is used to monitor the angle change of the arm joint in real time, and the acceleration sensor is used to monitor the movement acceleration of the arm in real time;

[0025] When the angle data of the arm joint monitored by the angle sensor in real time changes continuously from large to small, and the acceleration change of the arm monitored by the acceleration sensor is within the threshold range of the controller, it is judged that the arm is bent;

[0026] When the angle data of the arm joint monitored by the angle sensor in real time changes continuously from small to large, and the acceleration change of the arm monitored by the acceleration sensor is within the threshold range of the controller, it is judged that the arm is stretched;

[0027] When the frequency of change of the angle data of the arm joint monitored in real time by the angle sensor exceeds the frequency threshold of the controller, and the acceleration change of the arm monitored by the acceleration sensor is greater than the threshold of the controller and shows periodic changes, it is judged as daily activity.

[0028] Beneficial effects: By combining the data from the angle sensor and the acceleration sensor, the controller can more accurately determine the type of arm movement, thereby more accurately evaluating the tremor of the fistula blood vessels. This helps reduce false positives or false negatives caused by misjudgment. Accurate motion judgment logic ensures that the device does not issue unnecessary reminders or interference when the patient is doing daily activities, thereby improving the patient's wearing comfort and acceptance. Combined with the patient's daily activity data, medical staff can provide patients with more personalized care services. For example, according to the patient's activity habits and schedule, adjust the device's monitoring frequency and reminder method.

[0029] Furthermore, the controller signal is connected to an abnormality recording module, which is used to automatically record the time and type of each internal fistula vascular abnormality, monitoring component displacement and protective shell loosening event.

[0030] Beneficial effects: The abnormality recording module can automatically record the time and type of each fistula vascular abnormality, monitoring component displacement, and protective shell loosening event. These events are crucial to assessing the patient's health status and the performance of the device. The abnormality recording module can accurately identify and record different types of events. For example, it can distinguish whether the fistula vascular abnormality is caused by poor blood flow, vascular compression, or other reasons; whether the displacement of the monitoring component is caused by patient activity or device loosening; and whether the protective shell loosening is caused by long-term wearing or external force. For each recorded event, the abnormality recording module will attach a timestamp of occurrence. This allows medical staff to easily track the chronological sequence of events and analyze potential correlations between them. By recording the time and type of fistula vascular abnormalities, the abnormality recording module provides medical staff with more comprehensive patient health data. These data help them diagnose the patient's health status more accurately and formulate corresponding treatment plans.

[0031] Furthermore, it also includes a wireless communication module, which is used for remote communication with an intelligent terminal or a medical center. The wireless communication module is connected to the controller signal. The wireless communication module transmits the monitoring data and abnormal reminders in the control in real time, so that medical staff can understand the patient's health status in time and provide remote guidance.

[0032] Beneficial effects: The wireless communication module can communicate remotely with smart terminals (such as smart phones, tablets, etc.) or medical centers that support wireless communication. This communication method breaks the geographical restrictions and enables medical staff to obtain the patient's health data anytime and anywhere. The wireless communication module is connected to the controller signal, and can transmit the monitoring data (such as arm joint angle, motion acceleration, fistula vascular abnormalities, etc.) and abnormal reminders (such as monitoring component displacement, loose protective shell, etc.) in the controller to the smart terminal or medical center in real time. This ensures that medical staff can understand the patient's health status in a timely manner. Through the wireless communication module, medical staff can obtain the patient's health data in real time, so as to quickly make a diagnosis and formulate a treatment plan. This greatly improves medical efficiency and shortens the time patients have to wait for treatment. Medical staff can remotely monitor the patient's health status and promptly detect and deal with abnormal situations. This helps to enhance the management of patients and improve their treatment compliance and quality of life.

[0033] Furthermore, it also includes an early warning module, which is connected to the controller signal. The early warning module is used to issue an early warning based on the judgment result of the controller. The early warning component includes an indicator light and a buzzer. The indicator light flashes and emits light of different colors to indicate different warning levels, and the buzzer emits an alarm sound.

[0034] Beneficial effects: The early warning module is connected to the controller signal and can receive the judgment results of the controller in real time. When the controller detects events such as abnormal fistula blood vessels, displacement of monitoring components, loosening of protective shells, etc., the early warning module will start immediately. The early warning component includes an indicator light and a buzzer, which can provide visual and auditory dual warnings. The indicator light can flash and emit different colors of light to indicate different warning levels, such as red for emergency warnings, yellow for general warnings, etc. The buzzer can sound an alarm to alert patients and medical staff. The early warning module can automatically divide the warning levels according to the judgment results of the controller and the preset early warning rules. Different levels of warnings correspond to different warning methods and treatment measures, which helps medical staff quickly understand the patient's health status and take corresponding actions. The addition of the early warning module enables the device to issue an early warning in time when an abnormal situation is detected, alerting patients and medical staff, helping to avoid potential health risks and improve patient safety.

[0035] Furthermore, it also includes a power management module, which is used to manage the power supply of the device. The power management module includes a battery pack, a charging interface and a power management chip. The battery pack is used to provide power to the entire device. The charging interface is used to connect an external power source to charge the battery pack. The power management chip is responsible for monitoring the power status of the battery pack and reminding the user to charge through the early warning module when the power is low. An installation groove for placing the battery pack is embedded on the outer wall of the protective shell, and the charging interface is opened on the side wall of the installation groove.

[0036] Beneficial effects: As the main power source for the entire device, the battery pack can continuously provide the required power for the device. This ensures that the device can perform functions such as monitoring, early warning and communication normally without being restricted by an external power source. The charging interface is used to connect an external power source to charge the battery pack. This design allows the device to be easily charged through an external power source when the power is low, thereby extending the use time of the device. The power management chip is responsible for monitoring the power status of the battery pack and reminding the user to charge through the early warning module when the power is low. This intelligent management function ensures that the user can charge the device in time before the device runs out of power, avoiding problems such as device shutdown or data loss due to insufficient power. The addition of the power management module provides a stable and reliable power supply for the fistula vascular protection device and brings many beneficial effects. These improvements not only improve the performance and reliability of the device, but also provide patients with a more convenient and efficient way to manage their health.

[0037] Furthermore, an initial fixing component is installed on the outer wall of the protective shell. The initial fixing component includes a plurality of straps, which are fixedly connected to the outer wall of the protective shell. The two ends of the straps are respectively fixedly connected with a child Velcro and a mother Velcro.

[0038] Beneficial effects: The strap is fixedly connected to the outer wall of the protective shell. Through its flexibility and elasticity, it can fit the patient's limbs tightly and provide a preliminary fixing effect for the device. This design ensures that the device is not easy to slip or shift during wearing, thereby ensuring the accuracy of the monitoring and early warning functions. The two ends of the strap are respectively fixedly connected with a sub-Velcro and a mother Velcro. Through the sticking and separation of the Velcro, the user can easily adjust the tightness of the strap to adapt to the limb size and comfort requirements of different patients. This design not only improves the wearing convenience of the device, but also ensures the stability and comfort of the device during long-term wearing. The initial fixing component provides a preliminary fixing effect for the device through the design of the strap and Velcro. This ensures that the device is not easy to slip or shift during wearing, thereby ensuring the accuracy of the monitoring and early warning functions. At the same time, it also avoids the discomfort or harm to the patient that may be caused by the displacement of the device.

[0039] Furthermore, a plurality of ventilation holes are formed on the side wall of the protective shell, and the ventilation holes are evenly distributed on the side wall of the protective shell.

[0040] Beneficial effects: The ventilation holes are evenly distributed on the side walls of the protective shell, so that the air inside the protective shell can be exchanged with the external environment. This design ensures that when the device is worn for a long time, excessive heat and moisture will not accumulate inside the protective shell, thereby maintaining a comfortable wearing environment. The design of the ventilation holes allows the patient's skin to still breathe to a certain extent when wearing the device. This helps to reduce the stuffiness and discomfort caused by long-term closure of the skin, and improves the patient's wearing comfort. When the patient is active or in a high temperature environment, the ventilation holes help reduce the accumulation of sweat inside the protective shell. This reduces the risk of skin irritation and infection caused by sweat accumulation, and improves the safety and hygiene of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The following is further described in detail through specific implementation methods:

[0052] Embodiment 1:

[0053] As attached Figures 1 to 5As shown: a fistula blood vessel protection device for nephrology nursing, including a protective shell 1, the protective shell 1 is an arc-shaped structure, the protective shell 1 is installed with a monitoring component 6 for monitoring fistula blood vessel tremor and an adjustment component for adjusting the tightness of the protective shell 1, the adjustment component includes a power member 2, the output shaft of the power member 2 is fixedly connected to an adjustment rod 3, and a plurality of adjustment belts 4 are fixedly connected to the adjustment rod 3. The other end of the adjustment belt 4 passes through the protective shell 1, is wrapped around the protective shell 1, and is fixedly connected to the side wall of the protective shell 1. The length of the adjustment belt 4 is greater than the circumference of the protective shell 1, so that the tightness of the protective shell 1 can be adjusted by adjusting the length of the adjustment belt 4. The monitoring component 6 is fixedly connected to the moving component, and an installation chamber 101 is provided inside the protective shell 1. A through groove 102 is opened on the side wall of the installation chamber 101, and the side walls on both sides of the through groove 102 are fixedly connected to the first rack. The moving component includes a driving member, and the output shaft of the driving member is coaxially fixedly connected to a rotating wheel 5. The rotating wheel 5 is a gear structure, and the rotating wheel 5 is meshed with the first rack. The monitoring component 6 is installed on the side of the rotating wheel 5 away from the driving member; a fan heat component is installed on the inner wall of the protective shell 1, and the fan heat component includes a plurality of rotating shafts 7, and a plurality of fan blades 8 are fixedly connected to the rotating shaft 7. Both ends of the rotating shaft 7 are respectively rotatably matched with the side walls on both sides of the installation chamber 101, and the end of the adjusting rod 3 away from the power member 2 is coaxially fixedly connected to the main gear, and the main gear is meshed with the second rack 9. The second rack 9 is slidably matched with the side wall of the installation chamber 101, and the side wall of the installation chamber 101 close to the skin is a mesh structure, and the rotating shaft 7 is coaxially fixedly connected with a transmission gear 10, and the transmission gear 10 is meshed with the second rack 9. In this embodiment, the power member 2 is a first motor, and the driving member is a second motor.

[0054] The monitoring component 6 includes a vibration sensor for monitoring the tremor of the fistula blood vessels, a pressure sensor for monitoring the protection strength of the protective shell 1 on the patient's arm, an angle sensor and an acceleration sensor for monitoring the patient's daily activities. The power component 2 is signal-connected to the controller, and the vibration sensor, pressure sensor, angle sensor, acceleration sensor and driving component are all signal-connected to the controller.

[0055] The angle sensor is used to monitor the angle changes of the arm joints in real time, and the acceleration sensor is used to monitor the movement acceleration of the arm in real time; when the angle data of the arm joints monitored by the angle sensor in real time changes continuously from large to small, and the acceleration change of the arm monitored by the acceleration sensor is within the threshold range of the controller, it is judged that the arm is bent; when the angle data of the arm joints monitored by the angle sensor in real time changes continuously from small to large, and the acceleration change of the arm monitored by the acceleration sensor is within the threshold range of the controller, it is judged that the arm is stretched.

[0056] When the frequency of change of the angle data of the arm joint monitored in real time by the angle sensor exceeds the frequency threshold of the controller, and the acceleration change of the arm monitored by the acceleration sensor is greater than the threshold of the controller and shows periodic changes, it is judged as daily activity.

[0057] When the vibration sensor detects that the fistula blood vessel tremor is inconsistent with the threshold in the controller, and the angle sensor and acceleration sensor do not detect the patient's daily activities, it means that the fistula blood vessel is abnormal, and the controller reminds the patient to seek medical attention.

[0058] When the vibration sensor detects that the tremor of the fistula blood vessels is inconsistent with the threshold in the controller, and the angle sensor and acceleration sensor detect that the patient is performing daily activities, it means that the abnormality of the fistula blood vessels may be caused by daily activities. The controller reminds the patient to stop the ongoing daily activities, and the vibration sensor re-monitors the vibration of the fistula blood vessels.

[0059] When the vibration sensor cannot detect the tremor data of the internal fistula blood vessel and the monitoring data of the pressure sensor does not change, it means that the monitoring component 6 is displaced. The controller starts the driving member and drives the moving component through the driving member to reset the monitoring component 6.

[0060] When the vibration sensor cannot detect the vibration data of the internal fistula blood vessel, and the monitoring data of the pressure sensor does not match the threshold in the controller, it means that the protective shell 1 is loose, and the power part 2 is controlled to start and the elastic band of the protective shell 1 is adjusted.

[0061] The monitoring component 6 also includes a temperature sensor, which is used to monitor the temperature inside the protective shell 1 in real time. The temperature sensor is connected to the controller signal. When the temperature monitored by the temperature sensor is too high, the controller starts the power part 2 in the adjustment component to loosen the protective shell 1. At the same time, the adjustment rod 3 in the adjustment component drives the fan component to dissipate heat.

[0062] It also includes an early warning module, which is connected to the controller signal. The early warning module is used to issue an early warning based on the judgment result of the controller. The early warning component includes an indicator light and a buzzer. The indicator light flashes and emits light of different colors to indicate different early warning levels, and the buzzer emits an alarm sound.

[0063] In this embodiment, the monitoring component 6 can monitor a certain point of the internal fistula blood vessel, or it can monitor the entire internal fistula blood vessel of the forearm according to the monitoring path preset by the controller.

[0064] The specific implementation process is as follows: the thresholds of each sensor are preset in the controller, including the normal range of fistula tremor, the threshold of acceleration (used to judge the intensity of arm activity), the frequency threshold of angle change (used to distinguish daily activities from abnormal movements), and the comfortable range of temperature. These thresholds are determined based on medical research and clinical experience to ensure the accuracy and reliability of monitoring results.

[0065] According to the patient's preference, set the reminder method in the controller, such as sound reminder (buzzer), light reminder (indicator light flashes different colors) or vibration reminder. Make sure the reminder method can attract the patient's attention without causing unnecessary interference.

[0066] The patient wears the device on the arm, ensuring that the protective shell 1 can fit the arm tightly without being too tight to cause discomfort. The first motor is started by the controller to adjust the tightness of the adjustment belt 4, that is, the output shaft of the first motor rotates to wind the excess adjustment belt 4 onto the adjustment rod 3, so that the protective shell 1 can adapt to the arm size and comfort requirements of different patients.

[0067] After starting work, each sensor monitors the fistula blood vessel tremor, arm movement, temperature inside the protective shell 1, and the degree of protection of the patient's arm by the protective shell 1 in real time, namely:

[0068] The vibration sensor continuously monitors the tremor of the fistula blood vessels. Once an abnormal tremor is detected (exceeding the preset threshold), the controller immediately analyzes the data from the angle sensor and the acceleration sensor. For example, if the angle sensor detects that the angle data of the arm joint is undergoing a continuous change from large to small, and the acceleration sensor shows that the acceleration change of the arm is within the preset threshold range of the controller (indicating that this is a smooth, non-violent movement), this is usually interpreted as the arm being bent. On the contrary, if the angle data changes continuously from small to large, and the acceleration change is also within the threshold, it is regarded as the arm extending. In addition, if the angle and acceleration data show a pattern of periodic changes, this may mean that the patient is performing some regular daily activities, such as swinging the arms while walking.

[0069] If the abnormal tremor of the vibration sensor coincides with the bending, stretching or periodic movement of the arm (such as daily activities), the controller will remind the patient to suspend the activity and re-monitor through the early warning module (flashing indicator light, buzzer alarm). If the abnormality is not caused by daily activities, the controller will determine that there may be a problem with the fistula blood vessel and immediately activate the advanced warning to remind the patient to seek medical treatment as soon as possible.

[0070] If the vibration sensor cannot detect the vibration data and the pressure sensor data is stable, the controller determines that the monitoring component 6 may be deviated from the position due to movement, and then controls the second motor through the controller. The second motor is an output shaft that drives the rotating wheel 5. The rotating wheel 5 rotates through the first racks on both sides of the through slot 102, so that the monitoring component 6 is displaced, thereby achieving more accurate monitoring.

[0071] If the vibration sensor cannot detect vibration and the pressure sensor data is abnormal, the controller determines that the protective shell 1 may be loose, and controls the first motor to rotate again through the controller to further wind the adjustment belt 4 onto the adjustment rod 3, thereby further adjusting the tightness of the protective shell 1.

[0072] The temperature sensor continuously monitors the temperature inside the protective shell 1. Once the temperature is too high, the controller not only starts the power part 2 to slightly loosen the protective shell 1 to promote air circulation, but also activates the fan heat assembly. The fan heat assembly consists of a plurality of rotating shafts 7 and fan blades 8. Each rotating shaft 7 is fixedly connected to a plurality of fan blades 8 for generating wind flow for heat dissipation. The two ends of the rotating shaft 7 are respectively rotated with the side walls of the installation chamber 101 to ensure that the fan blades 8 can rotate smoothly. The main gear connected to the adjustment rod 3 is meshed with the second rack 9, and the second rack 9 is slidably matched with the side wall of the installation chamber 101. When the power part 2 drives the adjustment rod 3 to move, the main gear drives the second rack 9 to slide on the side wall. When the second rack 9 slides, it drives each rotating shaft 7 and fan blade 8 to rotate through the transmission gear 10, thereby generating wind flow. The side wall of the installation chamber 101 close to the skin is designed as a mesh structure. This design allows wind flow to pass through and directly contact the patient's skin, thereby improving the heat dissipation efficiency.

[0073] According to the judgment result of the controller, the early warning module (including indicator light and buzzer) sends out early warning signals of different levels. The indicator light can flash different colors according to the situation (such as red for emergency medical treatment, yellow for suspension of activities and re-monitoring, and blue for normal monitoring), and the buzzer sends out alarm sounds of different frequencies or tones. Patients take corresponding actions according to the prompts of the early warning module, such as suspending activities, re-monitoring or seeking medical treatment.

[0074] Specific examples:

[0075] Patient A wore the device of the present invention and suddenly felt discomfort in the area of ​​the fistula blood vessels while doing daily housework. At this time, the vibration sensor detected the abnormal tremor and immediately sent an alarm to the controller. The controller quickly analyzed the data from the angle sensor and the acceleration sensor and found that the arm was undergoing a normal bending movement and the acceleration change was also within the preset range. However, after the arm movement stopped, the abnormal tremor did not alleviate. Based on these data, the controller determined that the abnormal tremor was not caused by daily activities, but that there might be problems with the fistula blood vessels themselves. Therefore, it immediately activated the advanced early warning mechanism, the indicator light flashed red, and the buzzer issued a rapid alarm sound, prompting patient A to seek medical treatment as soon as possible.

[0076] Embodiment 2:

[0077] The difference from Example 1 is that the controller signal is connected to an abnormality recording module, which is used to automatically record the time and type of each occurrence of internal fistula blood vessel abnormality, displacement of the monitoring component 6 and loosening of the protective shell 1.

[0078] The specific implementation process is as follows: The vibration sensor continuously monitors the tremor of the fistula blood vessel and transmits the monitoring data to the controller in real time. The controller determines whether the fistula blood vessel is in an abnormal state based on the preset tremor threshold. Once the tremor abnormality is detected (such as amplitude exceeding the preset range, abnormal frequency, etc.), the controller immediately triggers the abnormality recording module.

[0079] After receiving the trigger signal from the controller, the abnormal recording module first marks the abnormality according to the type (abnormal fistula blood vessel, displacement of monitoring component 6, loose protective shell 1). At the same time, the module automatically records the timestamp of the abnormal event to ensure that each record contains accurate time information. The recorded event information (including event type, timestamp, etc.) will be stored in the built-in memory. The memory should have sufficient capacity to save abnormal records for a long time to facilitate subsequent analysis and query. Medical staff or researchers can regularly download and analyze the data in the abnormal recording module to understand the tremor of the fistula blood vessel, the stability of the monitoring component 6, and the tightness of the protective shell 1.

[0080] Embodiment 3:

[0081] The difference from Example 2 is that it also includes a wireless communication module, which is used for remote communication with a smart terminal or a medical center. The wireless communication module is connected to the controller signal. The wireless communication module transmits the monitoring data and abnormal reminders in the control in real time, so that medical staff can understand the patient's health status in time and provide remote guidance.

[0082] The specific implementation process is as follows: The wireless communication module can transmit the monitoring data and abnormal reminders in the controller to the smart terminal (such as mobile phones, tablets, etc.) or medical center in real time. Support long-distance data transmission to ensure that medical staff can understand the patient's health status in a timely manner. Use a secure data transmission protocol to ensure the security and privacy of monitoring data during transmission. Select appropriate wireless communication protocols and technologies, such as Wi-Fi, Bluetooth, ZigBee, LoRa, NB-IoT, etc., according to application scenarios and transmission requirements. Configure the network parameters of the wireless communication module, such as SSID, password, IP address, etc., to ensure that the module can connect normally to the smart terminal or the server of the medical center. Write the corresponding communication protocol and data format to ensure that the monitoring data can be accurately and completely transmitted to the receiving end.

[0083] The wireless communication module receives monitoring data and abnormal reminders from the controller in real time. The data is packaged into a specific format and transmitted to the smart terminal or medical center through a wireless channel. The receiving end (smart terminal or medical center) analyzes the received data and displays it to the patient or medical staff.

[0084] Medical staff can view the patient's monitoring data and abnormal reminders through smart terminals or medical centers. According to the data analysis results, they can provide remote guidance to patients, such as adjusting their living habits and conducting rehabilitation training. If necessary, medical staff can contact patients for further consultation or advice.

[0085] Embodiment 4:

[0086] The difference from Example 3 is that it also includes a power management module, which is used to manage the power supply of the device. The power management module includes a battery pack, a charging interface and a power management chip. The battery pack is used to provide power to the entire device, and the charging interface is used to connect an external power supply to charge the battery pack. The power management chip is responsible for monitoring the power status of the battery pack and reminding the user to charge through the early warning module when the power is low. An installation groove for placing the battery pack is embedded on the outer wall of the protective shell 1, and the charging interface is opened on the side wall of the installation groove.

[0087] The specific implementation process is as follows: The battery pack provides power support for the entire monitoring device to ensure that various sensors, controllers, wireless communication modules and other components can work normally. According to the power consumption and battery life requirements of the device of the present invention, select a suitable battery type and capacity, such as lithium-ion batteries, polymer batteries, etc. The charging interface is used to connect an external power source to charge the battery pack. According to the charging method of the battery pack and the type of external power supply, select a suitable charging interface, such as a USB interface, MicroUSB interface, Type-C interface, etc. The power management chip is used to monitor the power status of the battery pack, including the remaining power, charging status, etc., and remind the user to charge through the early warning module when the power is low.

[0088] Install the battery pack into the mounting slot in the protective case 1, and ensure that the battery pack is correctly connected to the power management chip. Connect the charging port to the power management chip, and ensure that the charging port can charge the battery pack correctly. Perform initial settings on the power management chip, including parameters such as power threshold and charging current. Debug the power management chip to ensure that it can accurately monitor the power status of the battery pack and issue a reminder through the early warning module when the power is low.

[0089] Embodiment 5:

[0090] The difference from Example 4 is that the outer wall of the protective shell 1 is installed with a primary fixing component, which includes a number of straps 11. The straps 11 are made of soft, durable and skin-friendly materials, such as nylon, polyester, etc. According to the size and shape of the protective shell 1, the length and width of the straps 11 are designed to ensure that the straps 11 can fit tightly against the protective shell 1 and be fixed on the patient's arm. Select a suitable position on the outer wall of the protective shell 1, and use sewing, bonding or other fixing methods to fix the straps 11 to the protective shell 1. Ensure that the straps 11 are firmly fixed and will not loosen or fall off during use. The two ends of the straps 11 are fixedly connected with a sub-Velcro and a mother Velcro respectively. The side wall of the protective shell 1 uses a drilling tool or a laser cutting device to open a number of ventilation holes on the side wall of the protective shell 1. According to the size and shape of the protective shell 1, the size, number and distribution position of the ventilation holes are designed. Ensure that the ventilation holes can be evenly distributed on the side wall of the protective shell 1 to maintain internal air circulation. The ventilation holes are evenly distributed on the side wall of the protective shell 1 , and the ventilation holes maintain air circulation inside the protective shell 1 .

[0091] The specific implementation process is as follows: When the patient wears the device of the present invention, the protective shell 1 is placed on the arm to ensure that the protective shell 1 fits tightly to the arm without affecting the normal movement of the arm. The protective shell 1 is initially fixed by the strap 11. Ensure that the strap 11 fits tightly to the protective shell 1 and the patient's arm to provide sufficient fixing force.

[0092] The tightness of the strap 11 is adjusted using the sub-velcro and the main Velcro to ensure that the strap 11 is neither too tight to cause discomfort to the patient nor too loose to cause the protective shell 1 to loosen or fall off.

[0093] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
