Abstract

A patient controlled single gang signaling device for use within a hospital communication network. The device contains two actuators, one for initiating an emergency distress call while the other initiates a non-emergency distress call. The emergency distress call actuator is controlled with a pull cord, thus enabling a patient to send out an emergency distress signal from a position away from the unit. The device also includes a third actuator providing the user with the option of terminating the transmission of any message.
