Data acquisition, storage and display system
First Claim
1. A medical data acquisition and storage system, comprising in combination:
- display means for providing a visual presentation of input medical data,input means reponsive to externally generated data and generating a plurality of input signals, said input means including means sensing the physiological variables of a patient and generating physiological input signals, and further including manual means for generating patient related input signals and system control signals,processor means responsive to the physiological input signals, said processor means including arithmetic means for converting the physiological input signals into binary codes representing measured variables of a patient, wherein a predetermined set of binary codes represents each measured variable,a register for sequentially receiving and holding each set of binary codes from said processor means,memory means having multiple address locations for storing binary codes holding in said register, anda controller connected to said processor means, said register and said memory, and including;
first means responsive to the patient related input signals and a control signal to sequentially transfer one set of binary codes for one measured variable from said processor means to said register;
second means responsive to the transfer of codes to said register to connect said register to said display means; and
third means responsive to a control signal and the connection of said register to said display means to transfer the binary codes from said register to said memory means.

Abstract
Medical data including temperature, respiration rate and pulse rate are measured and stored in an acquisition unit incorporating a circulating register for storing data covering many patients. An analog temperature signal is converted into binary coded decimal for visual presentation on a display of the acquisition unit. The display data is then stored in the acquisition unit memory by actuating a RECORD switch. An analog respiration rate signal and an analog pulse rate signal are also converted into binary coded decimal for sequential display and storage in the acquisition unit memory. Medical data from external sources may similarly be stored in the acquisition unit memory. This recording procedure is repeated for any number of patients desired up to the storage limit of the acquisition memory. Data stored in the acquisition unit is then transferred into a printer unit that accesses each memory location and prints the data on a separate label for each individual patient. The printer includes a hard wired minicomputer which reads in data from the acquisition unit and compares it with identifying codes for controlling a digital printer. Medical data for each patient stored in the acquisition unit is temporarily stored in a random access memory and sequentially compared with each of a plurality of identifying codes for control of the digital printer. After all patient data in the acquisition unit has been transferred into the printer memory, a signal is generated to enable clearing of the acquisition unit memory for subsequent use thereof.
