[0002] Infusion is a common method for treating diseases. Infusion therapy generally involves inserting a puncture needle into the patient's hand. During infusion, child patients are active by nature and afraid of puncture, so they often cry and become restless. This can easily cause the infusion needle to fall off and affect the normal progress of the infusion. Therefore, it is necessary to restrict the child's arm during infusion.
