Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a network-connected monitoring device for exercising the affected limb after arteriovenous fistula surgery. Background Technology

[0002] Maintenance hemodialysis is an essential alternative therapy for prolonging the lives of patients with chronic renal failure, and vascular access is an indispensable lifeline for hemodialysis patients. Autogenous arteriovenous fistulas (AVFs) are access routes established through subcutaneous anastomosis of arteries and veins. Due to their long lifespan and few complications, they have become the best vascular access route for maintenance hemodialysis. A mature and patent autogenous arteriovenous fistula is a fundamental condition for effective dialysis and long-term survival in maintenance hemodialysis patients. Previous studies have shown that 28%–53% of autogenous arteriovenous fistulas do not fully mature to meet the needs of hemodialysis; effective postoperative functional exercises of the affected limb are essential for the maturation of autogenous arteriovenous fistulas.

[0003] Existing postoperative exercise devices for arteriovenous fistulas are relatively simple in function, only having a recovery function and lacking monitoring and nursing functions. Summary of the Invention

Two limit holes are opened on the inner side wall of the fixed cylinder on the right side of the movable cylinder.

[0013] The beneficial effects of the arteriovenous fistula postoperative limb exercise device of the present invention, which can be monitored via network, are as follows:

[0014] By setting up a first airbag, an arc-shaped fixation plate, an ultrasound detector, a pressure sensor, a fixation cylinder, an extension rod, a cloth strip, and a buckle, the patient's limb is inserted into the fixation cylinder after surgery. The cloth strip is used to fix it to the bed or around the patient's neck to elevate the limb after arteriovenous fistula surgery, reduce limb edema, maintain smooth blood circulation, and thus prevent finger swelling. In addition, by moving the extension rod to adjust the position of the arc-shaped fixation plate, the first airbag on the left side is activated. The first airbag compresses the arc-shaped fixation plate close to the fistula, and the infrared lamp is activated through the smart display screen to apply heat to the fistula, improving the patency rate of the fistula and extending its lifespan. Then, the ultrasound detector is activated through the smart display screen to detect blood flow and determine the maturity of the fistula. Alternatively, the first airbag on the right side can be activated to compress the limb, and the pressure sensor detects the blood pressure. The data detected by the ultrasound detector and the pressure sensor are displayed on the smart display screen for easy viewing. Furthermore, the wireless signal transmission module can transmit the data to the network for others to view and understand.

[0015] The system consists of a rubber ball, a first air tube, a second air tube, a rotating block, a top block, a sliding rod, a pressure block, a first blocking ball, a second blocking ball, a second spring, a third spring, an air cylinder, a clamping block, a rotating cylinder, a moving cylinder, a top rod, a fixed rod, a first air hole, an air hole, a rotating ring, a connecting rod, a stop ring, a clamping block, and a blocking ring. Rotating the upper rotating cylinder moves the upper rotating ring, connecting rod, and clamping block. The upper stop ring presses against the clamping block, which clamps the upper first air tube. Then, rotating the upper rotating block moves, squeezing the upper top block, sliding rod, and pressure block. The upper pressure block squeezes the contacting second air tube, and then the rubber ball is pressed. The gas squeezed by the rubber ball pushes the upper first and second blocking balls upwards. The first blocking ball blocks the air vent, and the second blocking ball moves to open the blocking ring, allowing gas to enter the uncompressed second air tube and finally the first air bladder on the left. Releasing the rubber ball causes the second and third springs above to bring the first and second blocking balls back to their original positions. The second blocking ball then blocks the blocking ring to prevent air leakage, opening the first air vent for air intake. The rubber ball then returns to its original position. Pressing the rubber ball repeatedly moves the arc-shaped fixing plate for heat application. Rotating the lower rotating block blocks the second air tube, and reversing the upper rotating block returns the upper pressure block to its original position. Pressing the rubber ball inflates the first air bladder on the right, allowing for blood pressure monitoring.

[0016] By setting up a fixed frame, rubber bands, a movable plate, a second airbag, a motor, a screw, a slide plate, an electromagnetic block, gears, and a rotating rod, rotating the lower drum causes the lower clamping block to squeeze the lower first air tube, pressing the rubber ball. This allows gas to enter the second airbag from the upper first air tube. The second airbag pushes the movable plate, which in turn moves the electromagnetic block, deforming the rubber band. This exercises the hands. Starting the motor, through gear transmission, causes the rotating rod and screw to rotate. The screw's rotation raises the slide plate, which in turn pulls the rubber band, increasing... Already The tension of the rubber band on the moving board can be adjusted to control the resistance of the fist. The moving cylinder is positioned on the upper arm to apply pressure to the upper arm. Then, the user holds the rubber ball to exercise. The exercise is recorded by a camera and transmitted to the network via a wireless signal transmission module for doctors to view and understand. The wireless signal transmission module receives feedback from doctors and displays it on a smart display screen. Attached Figure Description

The internal part of the cylinder 53 is equipped with a wireless signal transmission module 54. A support rod 61 is fixed to the outer wall of the upper moving rod 1, and a camera 60 is fixed to the outer wall of the support rod 61. A pressure sensor 13 is fixed to the inner wall of the moving cylinder 63, located outside the first airbag 49.

The upper abutment ring 20 presses against the clamping block 25, and the clamping block 25 clamps the upper first air tube 3. Then, rotating the upper rotating block 18 moves and squeezes the upper top block 31, sliding rod 34, and pressure block 35. The upper pressure block 35 squeezes the contacting second air tube 4. Then, pressing the rubber ball 2, the gas squeezed by the rubber ball 2 pushes the upper first blocking ball 15 and second blocking ball 26.The first blocking ball 15 blocks the air vent 12, and the second blocking ball 26 moves to open the blockage ring 14, allowing gas to enter the uncompressed second trachea 4 and finally the first airbag 49 on the left.

Rotate the lower rotating cylinder 19, and the lower clamping block 25 compresses the lower first air tube 3. Press the rubber ball 2, and gas enters the second airbag 40 from the upper first air tube 3. The second airbag 40 pushes the moving plate 36 to move. The moving plate 36 deforms the rubber band 38, thus exercising the hands. Start the motor 46. The motor 46 drives the rotating rod 43 and the screw 41 to rotate through the gear 44. The rotation of the screw 41 raises the slide plate 39. The rising slide plate 39 pulls the rubber band 38, increasing the tension of the rubber band 38 on the moving plate 36, which can adjust the resistance of clenching the fist.

[0029] like Figures 1 to 5As shown, in this embodiment, two second air tubes 4 are fixed inside the lower moving rod 1. The right ends of the two second air tubes 4 pass through the lower moving rod 1, the fixed cylinder 10, and the two cylinders 5 respectively and are fixedly connected to the outer walls of the two first airbags 49.

The other end of the left cloth strip 55 is fixed with a buckle 50, and the other end of the right cloth strip 55 passes through the buckle 50. A leather sleeve 51 is fixed to the outside of the left cloth strip 55. This allows the cloth strip 55 to be fixed to the bed or around the patient's neck, elevating the limb undergoing arteriovenous fistula surgery, reducing limb edema, maintaining smooth blood circulation, and thus preventing finger swelling.

[0035] like Figure 8 As shown, in this embodiment, two fixing blocks 62 are fixed on the left side of the movable cylinder 63. A storage hole 64 is provided on the side of the fixing block 62 near the fixed cylinder 10. A sixth spring 65 is fixed inside the storage hole 64. A limit block 66 is fixed at the other end of the sixth spring 65. Two limit holes 67 are provided on the inner side wall of the fixed cylinder 10 on the right side of the movable cylinder 63, thus restricting the movement of the movable cylinder 63.

[0036] The working principle of this device is as follows: Rotating the upper rotating cylinder 19 moves the upper rotating ring 24, connecting rod 21, and clamping block 25. The upper abutment ring 20 presses against the clamping block 25, which clamps the upper first air tube 3. Next, rotating the upper rotating block 18 moves, squeezing the upper top block 31, sliding rod 34, and pressure block 35. The upper pressure block 35 squeezes the contacting second air tube 4. Then, pressing the rubber ball 2 compresses the gas, pushing the upper first blocking ball 15 and second blocking ball 26. The first blocking ball 15 blocks the air hole 12, and the second blocking ball 26 moves to open the seal of the blocking ring 14, allowing gas to enter the uncompressed interior of the second air tube 4. Then, the first airbag 49 on the left is inserted, and the rubber ball 2 is released. The second spring 16 and the third spring 27 above bring the first blocking ball 15 and the second blocking ball 26 back to their original positions, respectively. The second blocking ball 26 blocks the blocking ring 14 to prevent air leakage. The first air hole 12 opens to allow air in, and the rubber ball 2 returns to its original position. Then, the rubber ball 2 is pressed repeatedly, and the first airbag 49 squeezes the arc-shaped fixing plate 7 close to the fistula. The infrared lamp 59 is activated through the intelligent display screen 52 to apply heat to the fistula, improve the patency rate of the fistula, and extend the life of the arteriovenous fistula. Then, the ultrasound detector 8 is activated through the intelligent display screen 52 to detect blood flow and determine the maturity of the fistula. Then, the rotating block 18 below is rotated to allow air to enter. Second trachea 4 blockedReverse the upper rotating block 18, return the upper pressure block 35 to its original position, and press the rubber ball 2. This inflates the first airbag 49 on the right side, compressing the limb. The pressure sensor 13 senses the blood pressure, allowing for blood pressure monitoring. Data from the ultrasonic detector 8 and the pressure sensor 13 are displayed on the smart display screen 52 for easy viewing. Furthermore, the wireless signal transmission module 54 can transmit the data to the network for others to view. Rotate the lower rotating cylinder 19, causing the lower clamping block 25 to compress the lower first air tube 3. Pressing the rubber ball 2 allows gas to enter the second airbag 40 from the upper first air tube 3. The second airbag 40 then pushes the moving plate 36 to move. The movement of 36 deforms the rubber band 38, thus exercising the hand. The motor 46 is activated, and the motor 46, through the gear 44, causes the rotating rod 43 and the screw 41 to rotate. The rotation of the screw 41 causes the slide plate 39 to rise. The rise of the slide plate 39 pulls the rubber band 38, which increases the tension of the rubber band 38 on the moving plate 36. This can adjust the resistance of the fist. The moving cylinder 63 is positioned at the upper arm position to apply pressure to the upper arm. Then, the user holds the rubber ball 2 to exercise. The exercise is recorded by the camera 60 and transmitted to the network via the wireless signal transmission module 54 for the doctor to view and understand. The wireless signal transmission module 54 receives feedback from the doctor and displays it on the smart display screen 52.
