[0002] Hemodialysis is a common method for treating renal failure. With the increasing trend of population aging, the number of patients with chronic kidney disease is increasing. Since the dialysis time is more than 4 hours, the patient needs to take a supine position for a long time and cannot change the body position at will. During the dialysis process, the patient is likely to move the upper limbs when sleeping, which causes the puncture needle to separate from the blood vessel, seriously affecting normal hemodialysis, and even endangering the patient's life in severe cases.
