Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a medical wristband material for carbon ribbon printing and a preparation method thereof. Background technique [0002] In the hospital, each doctor or nurse has to face a large number of patients every day, and it is difficult to remember the specific information of each patient. At present, most of the information of each patient in the hospital, especially the information of inpatients, is recorded on a card, and then the card is directly placed at one end of the patient's bed. This way of using the card is easy to be lost or even replaced. problem, for which wrist straps worn on the patient's wrist have arisen. [0003] Medical wristband, also known as medical identification belt, is a kind of wristband. Medical wristband can provide patient identification information. It is an effective tool for doctors to identify patients. Medical wristbands of various colors ca...
