#6,112,224 : Electronic House Calls Patent
Abstract: A patient monitoring system for use in a telemedicine system that allows multiple medical devices to communicate with a control unit via an interface that uses a single interrupt. In architecture, the system can be implemented in hardware, or a combination of hardware and software, and is more particularly implemented as follows: A plurality of medical devices are connected to a control unit via a device interface that uses a single interrupt in the transmission of data from the medical devices to the control unit. When a medical device has data to transmit to the control unit,the medical device transmits data to the device interface, and the device interface uses its single interrupt line in the transmission of data to the control unit.
