[0002] A hospital care bracelet is usually a bracelet with the patient's personal information, which is used to identify the patient's identity, medical records and other important information. There is also a pair of care bracelets used by parents to restrain children to prevent children from getting lost when they are out of the caregiver's sight. It is a device that helps parents keep an eye on their children and prevents them from getting lost or lost when they are away from their caregivers.

[0003] Common care bracelets generally fix one end of the bracelet on the child's wrist and the other end on the caregiver's wrist. The caregiver will fix the limit rope at a certain length to limit the child's range of movement. The caregiver needs to actively adjust it when it needs to be extended or shortened. However, children usually run directly to the location when they encounter something they are interested in. When the child rushes out suddenly, the length of the limit rope is locked and fixed, which can easily cause the child to fall, causing injury to the child and affecting the care effect. The care bracelets used in hospitals are only worn on the patients' hands and do not have the function of prompting the supervisor, which can easily lead to the patient not being discovered in time when encountering an emergency.
