Wristbands can be very important, especially for children and elderly patients. Many people can't tell their ward, bed number and other information accurately, but they have to be checked and signed by doctors, nurses and anesthesiologists before and after the operation. This means that the patient is allergic to latex. Since most hospital gloves and many hospital tools contain latex, if possible, these bracelets will remind nurses when substitutes are needed. These bracelets usually include a big letter "L".
There may also be cases where the color of the wristband is not enough. At this time, it needs special customization. Some hospitals will use wrist straps to distinguish patients with different symptoms, but some hospitals will use wrist straps to distinguish the severity and urgency of patients. The purpose of distinguishing the colors of wristbands is to let nurses identify the patient's condition more quickly. Endangered patients (grade 1, marked with red wristband) and critically ill patients (grade 2, marked with yellow wristband) identify that the wristband is tied to the patient's wrist. The identification band marked with important information of patients can effectively ensure that medical staff can identify patients quickly and accurately at any time, prevent them from being replaced or removed at will, and ensure the uniqueness and correctness of the identified objects.
There are also black ones, but they can be seen mainly in mental hospitals, representing "self-abandonment". It means that the patient has or may have given up on himself and even tried to end his life by hanging himself or hitting his head. Medical staff must always be on high alert. Wristbands of different colors represent the situation of patients of different levels. The red wristband is used for the first-class serious illness, the permanent yellow wristband for the second-class, the blue wristband for the third-class, and the green wristband for the fourth-class.
