Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0030] Figure 2 It is a schematic structural diagram of a patient holding the present invention.

[0031] Figure 3 It is a control schematic diagram of the time and quantity monitoring system of the present invention. Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0033] Refer to Figures 1 - 3 As shown, a multifunctional grip strength exercise device applied after arteriovenous fistula surgery is given in the figure, which includes an annular grip body 100 and a time and quantity monitoring system 200.

[0034] The annular grip body 100 is used for the hand 500 of a patient after arteriovenous fistula surgery to squeeze to exercise the arm muscles and achieve early maturation of the fistula. Using the annular grip body is convenient for the patient to hold the hand during the early maturation exercise of the fistula, and it is more convenient for the patient to perform the corresponding exercise operation.

[0035] When a patient after arteriovenous fistula surgery performs early maturation exercise of the fistula through the annular grip body, the time and quantity monitoring system 200 can effectively monitor the exercise time and squeezing quantity. The time and quantity monitoring system 200 is arranged on the annular grip body 100 and is communicatively connected with a patient status monitoring system arranged at the nurse's station for monitoring the patient's exercise situation.

[0036] The annular grip body 100 includes a first arc-shaped extrusion part 110 and a second arc-shaped extrusion part 120. Two ends of the second arc-shaped extrusion part 120 are respectively connected to two ends of the first arc-shaped extrusion part 110 through arc-shaped connecting parts 130.

[0037] When a patient after arteriovenous fistula surgery performs early maturation exercise of the fistula, the first arc-shaped extrusion part 110 contacts the index finger, middle finger, ring finger and little finger of the hand, while the second arc-shaped extrusion part 120 contacts the palm of the hand 500 of the patient when performing early maturation exercise of the fistula.

[0038] A placement cavity 112 for placing the time and quantity monitoring system 200 is provided in the middle of the first arc-shaped extrusion part 110. The time and quantity monitoring system 200 can be integrally snap-fitted into the placement cavity 112. When the battery needs to be replaced or corresponding abnormal handling is required, only the time and quantity monitoring system needs to be snapped out of the placement cavity for corresponding operations.

[0039] On the outer ring surface where the first arc-shaped extrusion part 110 contacts the index finger, middle finger, ring finger, and little finger of the patient's hand, there are finger positioning grooves 111 for effectively positioning the corresponding fingers and preventing the corresponding fingers from sliding on its outer ring surface. On the surface where the second arc-shaped extrusion part 120 contacts the palm of the patient's hand, there are also a plurality of anti-slip particles for preventing the second arc-shaped extrusion part from slipping out of the patient's palm during the exercise process.

[0040] The annular grip body 100 is integrally injection-molded from a highly elastic rubber material. When the patient holds the annular grip body 100, the contact between point A 300 and point B 400 inside its inner ring is regarded as one effective exercise, and the counting sensor 270 calculates it as 1 time. The overall elasticity and comfort of the annular grip body made of a highly elastic rubber material are relatively good, further improving the comfort of the patient when using the annular grip body for corresponding exercises.

[0041] The time and quantity monitoring system 200 includes a housing 210, a timer 240, a controller 220, a liquid crystal display screen 250, and a power module 230. The housing 210 is matched with the placement cavity 112. With this structure, it is convenient to place it into the placement cavity or take it out of the placement cavity.

[0042] When a patient who has undergone arteriovenous fistula surgery conducts early fistula maturation exercises, the counting sensor 270 can count and monitor the effective number of times the annular grip body is squeezed. The counting sensor 270 is arranged inside the housing 210.

[0043] When a patient who has undergone arteriovenous fistula surgery conducts early fistula maturation exercises, the timer 240 can effectively monitor the exercise time. The timer 240 is arranged inside the housing 210. When the patient conducts corresponding exercises, the counting sensor 270 sends the corresponding exercise signal to the controller 220. After receiving the first exercise signal from the counting sensor 270, the controller 220 sends the corresponding signal to the timer 240, and the timer 240 starts the corresponding timing work.

[0044] The controller 220 is respectively communicatively connected to the counting sensor 270, the timer 240, and the patient status monitoring system arranged at the nurse's station for monitoring the patient's exercise situation.

[0045] The liquid crystal display screen 250 is numbered and used to display the patient's name, exercise time, and extrusion quantity. The liquid crystal display screen 250 is arranged on one side of the housing 210 close to the patient's face and is communicatively connected to the controller. The power module 230 is respectively electrically connected to the counting sensor 270, the timer 240, the controller 220, and the liquid crystal display screen 250.

[0046] The time and quantity monitoring system further includes a vibrator 260 that emits a vibration signal to remind the patient to exercise or stop exercising when the patient fails to perform early maturation exercises on the internal fistula within the set time or when the exercise quantity is reached within the set time. The vibrator 260 is arranged inside the outer housing 210, and is respectively communicatively connected to the controller and electrically connected to the power module.

[0047] The time and quantity monitoring system further includes a traffic light structure 280 that emits a light signal to remind medical staff of the corresponding operations of the patient when the patient fails to perform early maturation exercises on the internal fistula within the set time or when the exercise quantity is reached within the set time. The traffic light structure 280 is arranged at the platform of the patient status monitoring system, and is respectively electrically connected to the power supply of the patient status monitoring system and communicatively connected to the controller.

[0048] The counting sensor 270 is a combination of a Hall sensor and a magnet or a touch sensor. This effectively improves the sensitivity of the counting sensor and can accurately and effectively count the relevant quantity of the patient's exercise.

[0049] The working principle of the present invention is as follows:

[0050] It is necessary to perform early maturation exercises on the arteriovenous internal fistula patient. For example, this patient is Zhang San. First, the medical staff inputs parameters such as Zhang San's exercise time, quantity, and interval time into the controller through the patient status monitoring system according to Zhang San's relevant situation;

[0051] When the patient fails to perform the corresponding exercise after the interval time has passed, the controller will control the vibrator to emit a vibration to remind the patient to perform the corresponding exercise. At the same time, the controller controls the red light of the traffic light structure arranged at the platform of the patient status monitoring system to turn on, and reminds the medical staff that patient Zhang San has not performed the corresponding exercise work within the specified time. If the vibration signal fails to make the patient perform the corresponding exercise, the medical staff needs to promptly remind the patient to perform the corresponding exercise work;

[0052] When the patient starts to perform the corresponding early maturation exercises on the internal fistula, the counting sensor will effectively count the quantity of the patient's exercise and can send the first counting signal to the controller. After receiving the first exercise signal from the counting sensor, the controller sends the corresponding signal to the timer, and the timer starts to perform the corresponding timing work. Through the dual monitoring work of counting and timing, the patient's exercise work is effectively monitored, and the patient needs to complete the set quantity of exercises within the set time.

[0053] When the set number of exercises is completed within the set time, the controller sends a relevant completion signal to the vibrator, and the vibrator emits a vibration signal to remind the patient that the exercise has reached the standard, and the corresponding exercise work can be stopped. At the same time, the controller controls the green light of the traffic light structure to turn on, and reminds the medical staff that patient Zhang San has completed the set number of exercise work within the set time, and the relevant parameters will be effectively displayed on the liquid crystal display screen. For example, for patient Zhang San, the grip strength exercise time is 20 minutes, and the grip strength count is 150.

[0054] In summary, the overall design of the present invention is reasonable, the structure is simple, the operation is convenient. The exercise time and quantity can be customized according to the patient's own situation by using the time and quantity monitoring system, and the patient's hand can be fully exercised, and the filling degree of the patient's arteriovenous fistula can meet the clinical usability requirements. At the same time, when the patient is performing the corresponding fistula maturation exercise, the medical staff can carry out appropriate monitoring work, and can also intuitively understand whether the patient has carried out effective exercise, and make the exercise effect more ideal, thus bringing great convenience to the patient's fistula maturation exercise work.
