Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an arteriovenous fistula grip strength training device and monitoring system. Background Technology
[0002] In modern medicine, acute and chronic renal failure has become a serious threat to human health. Hemodialysis is the primary renal replacement therapy for patients with acute and chronic renal failure. Arteriovenous fistula (AVF) is a surgical procedure primarily used for hemodialysis. It is a vascular anastomosis surgery and plays an irreplaceable role as the vascular access for hemodialysis. However, only a mature AVF can provide sufficient blood flow for hemodialysis, ensuring the adequacy of the treatment. After AVF surgery, patients need to engage in appropriate exercises to promote fistula maturation and functional optimization. Exercise can enhance the elasticity of blood vessels and muscle strength in the arm on the fistula side, promote blood circulation, and thus accelerate the fistula maturation process. Traditional exercises often involve using a rubber grip ball, performing repetitive gripping movements to complete a specific exercise plan. This increases blood flow to the fistula, promotes vascular dilation and thickening of the vessel wall, enabling it to better adapt to the demands of hemodialysis.
[0003] However, a large proportion of maintenance hemodialysis patients are elderly, and they generally have poor adherence and memory, making it difficult for them to complete their exercise plans independently. They require constant supervision to control their grip strength and the number of repetitions. Furthermore, the optimal grip strength varies from person to person due to differences in age and arm strength on the side with the arteriovenous fistula. Ordinary rubber grip balls cannot measure a patient's grip strength and can easily damage blood vessels due to excessive or improper force. Secondly, when using ordinary rubber grip balls, it is impossible to know whether the prescribed number of repetitions has met the patient's grip strength, making it impossible to guarantee that each exercise will provide appropriate stimulation to the blood vessels, thus hindering the desired training effect and affecting the maturation progress of the arteriovenous fistula.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0024] Reference Figure 1 As shown in the figure, an arteriovenous fistula exercise gripper 1 provided by this utility model embodiment includes: a first gripping element 11, a second gripping element 12, an elastic element 14, a pressure sensor 21, a counter 23, and a controller 22.
[0025] Specifically, refer to Figure 1 and Figure 2As shown, the first gripping member 11 includes a first grip portion 110 and a connecting portion 111, which are integrally connected; the second gripping member 12 includes a second grip portion 120 and an annular portion 121, which are integrally connected, and the end of the connecting portion 111 near the first grip portion 110 is rotatably connected to the end of the annular portion 121 near the second grip portion 120; one end of the elastic member 14 is connected to the end of the annular portion 121 away from the second grip portion 120, and the other end is connected to the connecting portion 110. 1. Connection; a pressure sensor 21 is disposed in the first grip part 110 or the second grip part 120, and the pressure sensor 21 is used to measure the patient's grip force value; a counter 23 is disposed in the first grip force member 11 or the second grip force member 12, and the counter 23 is used to record the number of times the patient grips; a controller 22 is disposed in the first grip force member 11 or the second grip force member 12, and the pressure sensor 21 and the counter 23 are electrically connected to the controller 22 respectively, and the controller 22 is used to control the counter 23 to count when the measured value of the pressure sensor 21 is greater than or equal to a threshold.
[0026] When using the arteriovenous fistula (AGF) hand gripper 1, the patient naturally holds the AGF hand gripper 1 with the hand that underwent AGF surgery, with the fingers wrapped around the first grip 110. Typically, the index, middle, ring, and little fingers are placed on one side of the first grip 110, and the thumb is placed on the second grip 120. When gripping, ensure that the fingers and palm can fully contact the first grip 110 and the second grip 120 to find a comfortable and stable grip position. Slowly and with control, squeeze the AGF hand gripper 1, bringing the first grip 110 and the second grip 120 closer together. Completing one squeeze counts as one grip repetition. Repeat the squeezing action until the number of grip repetitions in the exercise plan is completed.
[0027] It is worth mentioning that arteriovenous fistula surgery is a surgical procedure used to establish a blood dialysis access. It mainly involves anastomosing and connecting the patient's artery and vein, allowing arterial blood to flow directly into the vein. This causes the vein to gradually expand and thicken, eventually forming a vascular access with sufficient blood flow and easy puncture, thus ensuring the blood dialysis process.
[0028] For example, the overall dimensions of the arteriovenous fistula (AVF) hand gripper 1 are, for example, 100mm wide and 200mm long, and the overall material is soft silicone. The pressure sensor can be, for example, a variable resistance rheostat or an adjustable pressure sensor; the controller can be, for example, an MCU or an FPGA; the counter can be, for example, a synchronous counter chip 74LS163; and the elastic element 14 can be, for example, a spring. The pressure sensor 21 is a device that can sense pressure and convert the pressure signal into an electrical signal. When the patient gradually applies force while using the AVF hand gripper 1, the pressure sensor 21 converts the pressure change generated by this grip force into an electrical signal, thereby accurately measuring the magnitude of the grip force and transmitting the data information to the controller 22. The controller 22 receives the input signal, processes it according to pre-set rules, algorithms, or logic, and then outputs control signals to manipulate the operating state of the target device or system.
[0029] More specifically, when the pressure sensor 21 measures the patient's grip strength and transmits the relevant grip strength information to the controller 22, the controller 22 compares the grip strength measured by the pressure sensor 21 with a preset threshold. If the grip strength is greater than or equal to the preset threshold, the controller 22 outputs a control signal to manipulate the counter 23 to count; if the grip strength is less than the preset threshold, the controller 22 does not output a control signal to manipulate the counter 23 to count. It should be noted that the preset threshold is a grip strength value set according to the patient's physical condition, arm strength, and the maturity of the arteriovenous fistula.
[0030] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula exercise gripper 1 also includes an elastic adjustment knob 15, which is disposed on the connecting part 111 and connected to the elastic element 14; the elastic adjustment knob 15 is used to adjust the grip strength of the arteriovenous fistula exercise gripper 1.
[0031] The elastic adjustment knob 15 allows setting the grip strength threshold based on individual patient differences and the maturity of the arteriovenous fistula. This threshold is fed back to the controller 22 in real time. The controller 22 then compares this threshold with the measurement value from the pressure sensor 21. Only when the pressure sensor's measurement value is greater than or equal to the threshold is the counter 23 activated, ensuring that each grip strength repetition reaches the patient's desired value during exercise, thus promoting fistula maturation and stability. The elastic adjustment knob 15 is easy to operate, caters to individual needs, and allows for real-time adjustment of the grip strength based on patient tolerance and fistula maturity. This ensures that each grip strength repetition provides the necessary stimulation to the blood vessel, enabling the fistula to mature at the ideal speed and with optimal quality, thus preparing the patient for subsequent hemodialysis treatment.
[0032] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula exercise gripper 1 also includes a repetition adjustment knob 16, which is disposed on the connecting part 111 and electrically connected to the controller 22; the repetition adjustment knob 16 is used to set the target number of exercises for the arteriovenous fistula exercise gripper 1.
[0033] The number of grip repetitions required for each set of exercises can be set by adjusting the repetition adjustment knob 16, and the set grip repetition data is transmitted to the controller 22 in real time. In the early postoperative period, the arteriovenous fistula vessels are relatively fragile, requiring only a small number of grip repetitions for gentle stimulation to promote blood circulation and initial vascular adaptation. As the exercise progresses, the vessels become more resilient, and the number of grip repetitions can be appropriately increased to accelerate fistula maturation. For example, if the patient's target exercise repetitions are 20 per set, and three sets are to be completed, the repetition adjustment knob 16 is rotated clockwise. The controller 22 then controls the display 24 to show the number of grip repetitions increasing sequentially. The repetition adjustment knob 16 is rotated clockwise until the number of grip repetitions displayed on the display 24 reaches 20. The grip repetitions adjusted by the repetition adjustment knob 16 work in conjunction with the grip strength value set by the elasticity adjustment knob 15 to create a more personalized rehabilitation exercise plan tailored to the individual patient's condition, which helps improve the efficiency and quality of fistula maturation.
[0034] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula hand gripper 1 also includes a display 24, disposed at the end of the second grip portion 120 away from the annular portion 121, and electrically connected to the controller 22; the display 24 is used to display the grip strength value and the number of grips under the control of the controller 22. Exemplarily, the display 24 may be an OLED liquid crystal screen.
[0035] The display 24 is electrically connected to the controller 22. When the controller 22 receives the measurement value fed back by the pressure sensor 21 and the count fed back by the counter 23, it transmits the data to the display 24 in real time to accurately display the grip strength value and the number of grips. Patients can use the number of grips displayed on the display 24 to determine whether they have completed a set of exercises and whether they have achieved their daily exercise goals. They can also adjust their grip strength according to their own situation based on the grip strength value displayed on the display 24 to ensure that the intensity of each exercise is within the appropriate grip strength range.
[0036] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula exercise gripper 1 also includes a voice broadcast module 25, which is disposed in the first gripping member 11 or the second gripping member 12 and electrically connected to the controller 22; the voice broadcast module 25 is used to broadcast relevant voice under the control of the controller 22.
[0037] When the controller 22 detects that the counter 23 has reached the number of grip strengths set by the count adjustment knob 16, it promptly transmits a control signal to the voice broadcast module 25. The voice broadcast module 25 broadcasts relevant voice messages such as "The target number of grip strengths has been completed." At the same time, the controller 22 transmits relevant data information from the pressure sensor 21 and the counter 23 to the voice broadcast module 25 in real time. When the patient completes a grip strength movement, the voice broadcast module 25 will broadcast the current grip strength value, such as "The current grip strength value is 8." After completing a set of grip strength movements, it will broadcast the number of grip strengths completed, such as "10 grip strengths have been completed, and there are 5 more grip strengths to reach the target number of grip strengths."
[0038] The voice broadcast module 25, combined with the display 24, provides real-time exercise information. For visually impaired patients, such as the elderly, voice prompts allow them to clearly understand their exercise intensity and progress, enabling them to independently follow the doctor's advice and ensuring the safety and effectiveness of their exercise during arteriovenous fistula rehabilitation.
[0039] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula exercise gripper 1 also includes a memory 26, which is disposed in the first gripping member 11 or the second gripping member 12 and is electrically connected to the controller 22; the memory 26 is used to store relevant data information of the arteriovenous fistula exercise gripper 1.
[0040] The memory 26 is electrically connected to the controller 22, enabling the controller 22 to transmit relevant data information during the use of the arteriovenous fistula exercise gripper 1 to the memory 26 for storage. At the same time, the controller 22 can also call up historical relevant data information in the memory 26 at any time to facilitate medical staff to analyze the patient's strength development and trends at different rehabilitation stages, help medical staff to judge the effectiveness of the rehabilitation plan, and make adjustments as needed to provide corresponding guidance to ensure the rationality and effectiveness of the exercise.
[0041] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula exercise gripper 1 also includes a wireless transmission module 27, which is disposed in the first gripping member 11 or the second gripping member 12 and is electrically connected to the controller 22; the wireless transmission module 27 is used to transmit relevant data information to external devices.
[0042] For example, the wireless transmission module 27 can be a WiFi module. The wireless transmission module 27 is electrically connected to the controller 22 to achieve data interaction, receiving various relevant data information from the controller 22, such as grip strength value and grip count, and wirelessly transmitting this data to an external device for remote monitoring. Medical staff can remotely monitor the patient's exercise status through an external device without being physically present, thereby promptly identifying abnormalities based on the exercise data and taking corresponding measures to improve medical efficiency and patient safety. Furthermore, medical staff can also perform comprehensive analysis of the exercise data to better evaluate the effectiveness of different exercise programs.
[0043] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the arteriovenous fistula exercise gripper 1 also includes a timer 29, which is disposed in the first gripping member 11 or the second gripping member 12 and is electrically connected to the controller 22; the timer 29 is used to record the time for completing the number of gripping exercises.
[0044] When a patient uses the arteriovenous fistula (AVF) hand grip strengthener 1 for exercise, the controller 22 controls the timer 29 to record the time taken to complete the required number of grips, and transmits this data to the memory 26 within the controller 22. By analyzing the changes in the time required to complete the same number of grips each time, healthcare professionals and patients can understand the improvement or decrease in the patient's exercise efficiency. For example, if the time it takes to complete a set of prescribed grips gradually shortens during exercise, it means that the function of the AVF is gradually improving, and the exercise is effective. Conversely, if the completion time becomes longer, it may indicate that the patient is fatigued, in poor condition, or that there are potential problems with the AVF. Appropriate adjustments to the exercise intensity or method can then be made to improve exercise efficiency and promote the maturation of the AVF.
[0045] In some embodiments of this utility model, reference is made to Figure 1 As shown, the arteriovenous fistula (AVF) hand gripper 1 also includes a first silicone sleeve 17 for placing the fingers and a second silicone sleeve 18 for placing the palm. The first silicone sleeve 17 is fixed to the first grip portion 110, and the second silicone sleeve 18 is fixed to the second grip portion 120. When the patient uses the AVF hand gripper 1, the first silicone sleeve 17 and the second silicone sleeve 18 can conform well to the contours of the fingers and palm, avoiding discomfort caused by prolonged gripping of the first grip portion 110 and the second grip portion 120. Especially when the patient needs to perform multiple, long-term exercises, it can effectively improve hand comfort during exercise.
[0046] More specifically, the arteriovenous fistula exercise gripper 1 also includes a power supply assembly 28, which includes a button portion 281. The power supply assembly 28 is disposed within the first gripping member 11 or the second gripping member 12, and the button portion 281 is exposed outside the housing of the arteriovenous fistula exercise gripper 1. The power supply assembly 28 is electrically connected to the button portion 281 and the controller 22, and the power supply assembly 28 is used to provide power to the arteriovenous fistula exercise gripper 1.
[0047] Additionally, refer to Figure 3 As shown, the present invention provides an arteriovenous fistula exercise monitoring system 3, comprising: an arteriovenous fistula exercise gripper 1 according to any of the preceding embodiments; and a network connection to the arteriovenous fistula exercise gripper 1 for receiving and monitoring data information from the arteriovenous fistula exercise gripper 1.
[0048] For example, the remote monitoring module 30 can be a mobile application. Medical staff can use the remote monitoring module 30 to obtain patient data in real time, analyze and evaluate the patient's exercise progress, and develop personalized exercise plans. Simultaneously, after discharge, patients can use the arteriovenous fistula exercise hand gripper 1 for rehabilitation exercises at home. The remote monitoring module 30 can transmit patient data to the hospital's telemedicine system, allowing medical staff to remotely guide and monitor the patient's exercise, ensuring the safety and effectiveness of the rehabilitation exercises. Furthermore, for elderly patients with poor compliance or memory, family members can use the remote monitoring module 30 to view data in real time, encouraging them to exercise effectively and accelerate the maturation of the arteriovenous fistula.
