[0039] The surfaces of the rubber ball 52 and the elastic grip ball 1 are all distributed with strip-shaped or circular anti-skid structures.

[0040] The working principle and working process of the utility model are as follows: Specific embodiment one:

[0041] When the arteriovenous fistula of a child patient is exercised, before the new type arteriovenous fistula exercise device is used, firstly, according to the exercise stage, the palm size and the grip strength of the child patient, the elastic grip ball 1 with a diameter of 5cm and a grip strength of 10 pounds is determined, the zipper 12 is pulled, the determined elastic grip ball 1 and the rubber tube 6, the rubber ball 52 and the rubber valve tube 51 are taken out from the storage bag 2, the external threaded tube 9 on the elastic grip ball 1 is threadedly connected to the threaded sleeve 8 on the rubber tube 6 to be firm, the device is comprehensively checked, it is ensured that all kinds of equipment are normal and the device has no air leakage phenomenon, the rubber ball 52 and the rubber valve tube 51 are orderly stored into the storage bag 2, and the purpose of convenient, clean and orderly is achieved.

[0042] The cuff 3 is unfolded, and the end of the cuff 3 provided with the hook-and-loop fastener 13 is attached to the skin of the patient, and is wrapped around the proximal end of the upper arm on the surgical side of the patient. The end of the cuff 3 provided with the hook-and-loop fastener 14 is attached to the end of the cuff 3 provided with the hook-and-loop fastener 13. The medical staff or accompanying personnel pinch the rubber ball 52, and at the same time, the air return valve 54 is closed, and the rubber valve pipe 51 is opened. The air in the rubber ball 52 enters the air bag 7 through the rubber valve pipe 51. After the hand is released, the rubber ball 52 automatically pops up and expands. At the same time, the rubber valve pipe 51 is closed, and the air return valve 54 is opened. The outside air is sucked into the rubber ball 52. The rubber ball 52 is repeatedly pinched and released to inflate and pressurize the air bag 7. If the pressure in the air bag 7 is slightly high, the air valve 53 can be unscrewed to release the air in the air bag 7 for adjustment. After the pressure in the air bag 7 reaches the required value, the air valve 53 is tightened to close. According to the requirements of the patient for arteriovenous fistula exercise, the surgical hand slowly grips the elastic grip ball 1. The air in the elastic grip ball 1 enters the air bag 7 through the rubber tube 6. The air bag 7 expands and presses the upper arm on the surgical side to prevent venous backflow. Arterial blood continues to be pumped in. The blood vessels will be tight and thick. After the required gripping time, the surgical hand releases the elastic grip ball 1. The elastic grip ball 1 automatically pops up and expands. The air in the air bag 7 is sucked into the elastic grip ball 1. The air bag 7 releases the pressure on the upper arm veins due to contraction. The venous blood flow increases, promoting the thickening of the blood vessels and the increase of the flow. According to the above, the elastic grip ball 1 is repeatedly gripped and released 20 times each time, 20 to 30 times a day, which helps to dilate the internal fistula vein and promote the maturation of the internal fistula. After the exercise is completed, the elastic grip ball 1, the rubber tube 6, the rubber ball 52, and the rubber valve pipe 51 are sequentially stored in the storage bag 2 and the zipper 12 is pulled to achieve the purpose of convenient, clean and orderly storage. Thus, the entire exercise process is completed.

[0043] The device adopts a design of replacing the elastic grip ball 1. According to the patient's own condition, the appropriate elastic grip ball 1 for the patient's exercise stage, palm size and grip strength can be selected. Old or damaged elastic grip balls 1 can also be replaced. The cuff 3 and the storage bag 2 are both provided with a soft and porous structure of gauze, so that the patient can experience a cool, skin-friendly and comfortable feeling. Specific embodiment two:

[0044] When an adult male patient is exercised on an arteriovenous fistula, before using the new arteriovenous fistula exercise device, first, according to the patient's exercise stage, palm size and grip strength, a 7cm diameter elastic grip ball 1 with a grip strength of 30 pounds is determined. The elastic grip ball 1 can fit the size of the patient's palm and improve the strength and flexibility of the hand, promoting the rehabilitation process. Then, the external threaded pipe 9 on the elastic grip ball 1 is threadedly connected to the threaded sleeve 8 of the rubber tube 6 to be firm. Repeat all the steps in the specific embodiment one to exercise the arteriovenous fistula.
