[0002] Hemodialysis is a common treatment for patients with end-stage renal disease, but long-term hemodialysis may cause pain in the arm on the fistula side. Currently, the main method used to relieve pain is insulation technology. One of the reasons for pain in fistula is vascular contracture. After the arm is kept warm and heated, the blood vessels in the arm will change from contracture to relaxation under the stimulation of high temperature, thereby relieving pain. However, traditional insulation methods will keep a large area of the patient's arm warm, and cannot directly keep the patient's blood vessels warm and heated, resulting in heat loss. Not only will the insulation period be shortened, but the pain relief effect on the patient will also be unsatisfactory. Utility Model Content
