Patient care and communication system
First Claim
1. A patient control unit, including:
- a housing;
a first switch mounted to the housing having a first terminal coupled to a first conductor and a second terminal coupled to a reference voltage; and
a self-test switch mounted to the housing having a first terminal coupled to a test conductor and a second terminal coupled to the first conductor;
wherein the self-test switch actuates in response to a test signal provided on the test conductor by a remote circuit thereby verifying continuity from the first switch first terminal to the remote circuit.

Abstract
The present invention relates to a patient care and communication system which utilizes a central processing system and a plurality of remote stations electrically connected to the central processing system to facilitate visual and data communications. Each remote station includes telephone circuitry which is connected to a private branch exchange for telephone communications between stations. In addition, the private branch exchange is connected to a telephone exchange and a plurality of telephones for facilitating telephone communication therebetween. The central processing system facilitates the visual and data communications between the plurality of remote stations, and includes a system for determining which of the plurality of remote stations are transmitting the visual and data communications and which of the plurality of remote stations are to receive the visual and data communications. The central processing system also includes a system which establishes a communication link between the transmitting stations and the receiving stations. The remote stations include a processing system which also facilitates the visual, data and telephone communications and a display for displaying the visual communications. The present invention also includes a staff and/or patient locator system, in which each remote station includes an infrared receiver that receives infrared transmissions from a portable transmitter worn by a staff member or patient. The infrared transmissions include identity information associated with the person wearing the transmitter. The identity information is then transferred to the central processing system which determines the identity and location of each person wearing a portable transmitter.
