Abstract
Abstract Disclosed is a hospital patient monitoring and display system employing a number of bedside consoles, concealable from the patient and including input for various patient sensors such as ECG, pulse rate, patient temperature and blood pressure. The consoles are powered by a low voltage direct current supply at a central station. The central station includes signal processing and display apparatus to allow the patient data to be displayed on a conventional commercial black and white or color television set along with alpha numerics related to each respective patient. The display is coupled to the hospitals normal entertainment television distribution network, if any, allowing the patient data to be displayed on any television set throughout the hospital. The signal processing and display portions of the system include a control to vary the trace speed and to freeze a display. A printer is connected to the display system to automatically print a reproduction of the display whenever the "freeze" control is actuated. A remote control operation via a radio frequency link may be carried by a patient's doctor and may be operated at any time or place within reception range of the central control to freeze the display for better examination and automatic printout of a reproduction. After a preset period, the display resumes. The system includes controls for setting maximum allowable values of various parameters and for sounding an alarm whenever the patient parameter varies from the allowable value. Such variation is registered as a shift from one color display to a different one in the case of color television sets, e.g. normal trace, green and abnormality, red. In the case of black and white displays, an alarm condition may be represented as intensity modulation or flashing of the display.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A patient monitoring system comprising a central control console including: a. a power supply; b. a controller for establishing alarm limits for patient data; c. a video translator for converting patient analog date into video traces representative of the analog values thereof; d. keyboard means for generating alpha numeric data; e. means for combining alpha numeric data with said video traces of patient analog data; f. means for introducing said combined data into a television distribution medium; at least one patient station including means connectable to patient sensor for amplifying a patient parameter sensor to a predetermined level; said amplifying means powered by said power supply of said central control console; means conducting said amplified parameter to said central control console; wherein said video translator includes means for storing analog patient data for a selected period of time and for introducing said data into said distribution system at the end thereof; and wherein said video translator includes means for establishing a WRITE and an ERASE cycle, including switch means for temporarily terminating the WRITE and ERASE cycle of said video translator and for enabling said recorder to record the analog data stored in said video translator.
