Input device for hard-wire patient monitoring system
First Claim
1. An input device for use in a hard-wire patient monitoring system, comprising:
- a case having a plug-in connector for plug-in connection to a patient monitoring system and a plurality of lines for receiving physiological input signals to be supplied to said patient monitoring system through said plug-in connector for processing said physiological input signals;
a memory storage device disposed in said case, and connected to said plug-in connector for storing and reading out patient data items necessary for monitoring a patient;
a backup battery power source disposed in said case and connected to said memory storage device for energizing said memory storage device when said case is disconnected from said patient monitoring system;
a switch disposed in said case for switching from a power supply of said patient monitoring system to said backup battery power source to maintain said memory storage device energized; and
means interconnected with said switch and said backup battery power source for actuating said switch in response to detachment of said case from said patient monitoring system.
