It is a necessary and sufficient nursing operation for patients with mental illness or poor compliance.

[0003] In the daily care process of pediatrics, due to the young age of children, they are not adaptable to various nursing operations and often do not cooperate with the operations. Especially for children with mental illnesses such as epilepsy, they will become confused and restless during convulsions. In severe cases, they will pull out needles and attack medical staff. At this time, it is necessary to restrain the children's limbs. It protects both the children and the medical staff. When fixing the limbs of child patients, parents or nurses usually press to fix the limbs; or use various soft cloth restraints, tie one end of the restraint to the child's limbs, and tie the other end to the bed.
