The invention relates to the technical field of medical appliances for passive exercise and particularly relates to a wristband for nursing internal arteriovenous fistula. The wristband for nursing the internal arteriovenous fistula comprises a wristband body used by a patient, wherein a three-way pipe is arranged inside the wristband body. three ends of the three-way pipe are separately connectedwith a connecting pipe, a massage airbag and an electromagnetic valve, the connecting pipe, the three-way pipe and the massage airbag communicate with one another, one end, far away from the three-way pipe, of the connecting pipe is used for inflating high-pressure gas, the massage airbag is located on the internal wall of the wristband body and is in contact with an arm of the patient, and a control module is further arranged inside the wristband body, is in signal connection with the electromagnetic valve and is used for controlling the make and break of the electromagnetic valve. By adopting the scheme, massage exercise on the arm of the patient subjected to an internal arteriovenous fistula surgery can be carried out to prevent angiemphraxis.
