Abstract
The present disclosure discloses a call system for a patient. The call system for the patient comprises a head-mounted device, a head motion detection module, an eyelid blinking detection module, a patient display screen, and a nurse station display screen. The head motion detection module collects relative changes of a head position through an aerial attitude sensor. The eyelid blinking detection module collects a movement distance and a movement duration of an eyelid through a photoelectric motion sensor. When the movement distance of the eyelid reaches a preset distance and the movement duration of the eyelid is longer than a preset duration, a confirmation command is generated to select one of multiple call services in a scroll menu, and the one of the multiple call services selected by the patient is sent to the nurse station display screen by a wired network or a wireless network.
