RAWSON Fl G, 5 BYJOHN B. DOWLING WM M7- ATTORNEYS DATA INTERPRETATION TERMINAL FIELD OF THE INVENTION This invention relates to electronic data communication and more particularly to data terminals for the remote entry of data into a computer.

BACKGROUND OF THE INVENTION In the automated medical screening of patients, a plurality of test stations are usually provided, each station being operative to provide a particular medical test and to enter data indicative of the results of such tests into a computer-based patient record. A particularly effective medical screening system is described in copending patent application Ser. No. 759,389, now U.S. Pat. No. 3,566,365, titled Multi-Phasic Medical Screening System, assigned to the assignee of the present invention. Test data is usually of an objective nature and is the result of specific tests performed on the patient. For example, in the analysis of blood and urine samples, test results obtained by well-known laboratory apparatus are entered into the patient record on a suitable terminal provided for the purpose. Similarly, test results respecting visual acuity, hearing, weight and height and the like are also entered into a patient record by means of respective data terminals. Certain medical tests such as radiology and cardiology tests require interpretation by a skilled physician in order to ascertain results of meaning in respect of the patients medical condition. It would be advantageous, and it is an object of the present invention to provide, a data entry terminal by which information interpretative of X-ray pictures, an ECG and the like can be assembled and transmitted to a computer-based medical record for entry therein.

SUMMARY OF THE INVENTION Briefly, a data entry terminal is provided for the real time entry of interpretive information into a eomputerbased medical record of a patient only by an operator having a valid identification code and in a manner which affords relatively simple and accurate operation. By virtue of the invention, interpretive phrases are ten tered into a patient record for later printing out in a form convenient and useful to an attending physician. Interpretations are entered by means of individual phrases which may be modified or deleted as subsequent entries are made. Operation of the terminal is enabled by means of an operator identification card which contains a coded representation of operator identity in order to permit terminal operation only by an authorized individual. Interpretive data transmitted by the terminal to the computer is returned to the terminal for display for purposes of data verification prior to entry into the patient record.

DESCRIPTION OF THE DRAWINGS FIG. 4 is a diagrammatic representation of the data format of messages directed by the terminal to a computer; and

FIG. 5 is a diagrammatic representation of the data format of messages received by the terminal from a computer.

DETAILED DESCRIPTION OF THE INVENTION A real time data entry system in which the invention is employed is illustrated in FIG. 1. A computer I0 is coupled to a data scanner 12 which, in turn, is coupled via a suitable transmission link I4 to a data interpretation terminal 16. Other like terminals may also be coupled to scanner 12, as can data terminals for other purposes such as described in the above-identified cope nding application. A teletypewriter I8 or other output device is also coupled to link 14 for providing a printed data output. As described in the aforesaid application, scanner 12 is operative to sequentially address each remote station, and to provide communication between each station and the computer for a selected interval of time, during which information is conveyed from the computer to the respective station and from a station back to the computer. Each data station is on-line with the computer at all times but is communicative therewith only during predetermined intervals.

The computer is typically of a type having a direct memory access capability such as a PDP-8l computer sold by the Digital Equipment Corporation. The data scanner l2 operative to control operation of the ter minal l6 and to provide communication between the terminal and computer 10, as well as other data ter minals and stations of the overall system, is described in the above-identified copending application.

The interpretation terminal is shown in a typical packaging configuration in FIG. 2. The terminal in eludes a plurality of push buttons 20 for definition of interpretive phrases and of a number to accommodate particular test requirements. The push buttons 20 are of the illuminating type and are each labeled to specify a predetermined interpretive phrase. A plurality of illuminating push button operating controls are also provided and include a START button 22 for commencing terminal operation, and ENTER button 24 for causing entry of interpretive data into the computer base patient medical record, and control buttons 26 for governing a data entry sequence. The buttons 26A denote respective phrases which are to be formed by use of console buttons 20. The CLEAR FIELD button 268 causes the erasure of numeric information as dis played on the displays 30 and 32. The END button 26C is actuated to denote the completion of a data entry sequence.

A data entry keyboard 28 is provided to cause entry of numerical information identifying a patient. The patient identification number is displayed on a numerical display 30, which typically is a multi-digit Nixie tube display, for visual verification by the operator prior to its entry into the computer-based patient medical record. A second numerical display 32 is provided to display a predetermined checking digit which is also entered via keyboard 28. A slot 34 is provided in the front panel of the terminal for receiving an operator identification card 36 which contains a coded identification number which is read by an associated card reader for transmission thereof to the computer. The

computer upon receipt of a valid operator identification code will cause transmission of command data to the terminal to initiate terminal operation. An annunciator display 49 is provided for displaying instructions to the terminal operator during the data entry process. In the illustrated embodiment, display 49 is of the rear projection type in which selected messages are projected upon a translucent screen for viewing by the operator. A buzzer is also provided within the terminal and is operative to warn of equipment malfunction or other illegal condition. A control 40 is provided for adjusting the volume of the signal buzzer and a test button 42 is also provided as a means for testing buzzer operation.

Three indicators are provided to instruct the terminal operator of steps to be performed and include an indicator 44, labeled PID, which upon illumination denotes a request for entry of a patient identification number via keyboard 28. A CHECK indicator 1 46 signals a request for entry of the predetermined check digit. A DATA indicator 48 signals a request for entry of interpretive data via controls and 26.

The terminal is operative to direct data words to the computer and for receiving data words therefrom. Such data words will hereinafter be referred to as the computer bound word and the terminal bound word respectively. In the illustrated embodiment a 24bit word format is employed. The computer bound word format is depicted in FIG. 4 and the terminal bound word format is depicted in FIG. 5. Two commands are employed for transmission from the terminal to the computer via a computer bound word. Command I contains data representing the actuated field indicators and console switches. Command 2, generated by actuation of START button 22, causes transmission to the computer of an operator identification number as read from the operator identification card 36. If the START button is depressed and no operator identification card is inserted, or if a card is inserted but contains an erroneous number, the computer will recognize the events and cause illumination of a suitable message (Illegal Data) on annunciator 38 to denote the illegal condition. If the computer receives a valid identification number, a terminal bound word is directed to the terminal to cause illumination of a Ready message on annunciator 38.

In the illustrated embodiment nine terminal bound word commands are employed. Command 1 causes information to be directed to the annunciator and buzzer, while commands 2 through 6 are employed to select banks of indicator lights associated with console buttons 20, 22, 24, and 26. Each console button lamp is illustrated by a single bit of a command, and the lamps are arranged in banks, each bank being associated with a command. Command 7 causes data to be written to displays 30 and 32; command 8 causes selected illumination of field lamps 44, 46, and 48; and command 9 is employed to clear the terminal registers. The station address is encoded in bit positions 17 of each terminal bound word command and the terminal is operative upon recognition of its address to permit decoding of the data content in the received command. The command identity is encoded in bits 8-1] of each computer bound word and terminal bound word. Bit 12 in the computer bound word when set denotes that data is to be entered by causing a computer interrupt.

Depression of a console button causes generation of a multi-bit code identifying that button and this data is assembled in a computer bound word for transmission to the computer. Upon receipt and decoding of this received data, the computer writes back in a terminal bound word to cause illumination of the button light associated with the selected console button. Information conveyed from the terminal to the computer is thus directed back to the terminal for purposes of verification. This information can be erased by depressing the button a second time. The computer, upon receipt of an identical button identification, recognizes this event as a command to erase the previously sent data.

Referring to FIG. 3, the computer bound words and terminal bound words are conveyed over the system transmission link coupled to a shift register control 60 which is operative to convey data to and from a shift re gister 62, and which is also operative to control the serial and parallel data transfer thereof. The console buttons 64, which include the buttons 20, 22, 24 and 26 shown in FIG. 2, and the data keyboard 28, are coupled to a switch decoder 66 which is coupled to enter logic 68 and which has a second output coupled to a fan-in network 70. Enter logic 68 is coupled to an encoder 72, the output of which is coupled to selected bit positions of shift register 62. A card reader 74 is coupled to enter logic 68 and also to fan-in network to provide a means for entry of an operator identification number in order to verify that data is being entered by an authorized individual.

The output of network 70 is coupled to selected bit positions of shift register 62. Shift register 62 is coupled to a station address decoder 76, which, in turn, is coupled to shift register control 60. The shift register is also coupled to a read/write decoder 78, an output of which is coupled to network 70. The shift register is also coupled to a plurality of buffers 80, 82 and 84, each of which also receives an input signal from the switch decoder 66. Each bulTer 80, 82 and 84 is associated with a respective lamp driver 86, 88 and 90. Lamp driver 86 is operative to energize message lamps 92 of annunciator 38, while driver 88 is operative to energize field lamps 94. Lamp driver 90 is operative to energize the lamps 96 associated with console buttons 20, 22, 24, and 26. The shift register 62 is also coupled to a display decoder driver 98 by way of associated buffer 100. Decoder 98 is coupled to a display indicator I02 identified in FIG. 2 as displays 30 and 32.

Actuation of one or more console buttons 64 and keys of data keyboard 28 causes corresponding signals to be applied to switch decoder 66 which identify the actuated switches and which provide a coded representation of the actuated switch identify to enter logic 68 and fan-in network 70. Switch decoder 66 is itself the subject of copending application Ser. No. 29,422 titled Switch Coding Circuitry and assigned to the assignee of the present invention. Briefly, this switch decoder is operative to ascertain the identity of an actuated switch within an array of mechanically unrelated and electrically distinct input switches and to provide a coded switch signal which is free of contact bounce noise and which is representative of a valid switch actuation.

In its standby condition, the terminal will display the message Insert ID on annunciator 38 as decoded from a terminal bound word received from the computer.

Upon insertion of an operator identity card in slot 34 and depression of START button 22, the operator identification number as read by card reader 74 is directed in a computer bound word to the computer which will ascertain whether the operator identification number is valid. If the number is not valid, the computer will direct a message to the terminal which will actuate an Illegal [D message on annunciator 38. If the identification number is valid, the computer will direct a message to the terminal which will cause illumination of field indicator 44 which signals the operator to enter the patient identification number. The indicator 44, as well as the other field indicators 46 and 48, are selectively activated by decoding of selected bits of a received terminal bound word by buffer 82 which, in turn, drives lamp driver 88 for actuation of the appropriate field lamps. Similarly, the annunciator messages are decoded by means of message buffer 80 which senses appropriate bits of a received word from the computer.

Upon entry of a patient identification number via keyboard 28, this data is directed to the computer and is returned to the terminal for energization of display 30 for visual verification by the operator. If the patient identification number is correct, actuation of ENTER button 24 causes entry of this number into computer memory. Upon depression of the ENTER button, the annunciator 38 will display a READY message, and indicator 46 will light to denote that a check digit is to be entered. A predetermined check digit is entered via keyboard 28, and if a valid digit is entered, indicator 48 will light calling for entry of interpretive data. Phrase 1 button 26A will also light, calling for entry of the first phrase, represented by buttons 20.

The operator will depress the buttons associated with the phrases descriptive of the interpretation being conducted. Certain of the buttons 20 will describe abnormalities while certain other of the buttons will describe the location of these abnormalities. Other buttons are provided for qualifying statements such as new finding." Depression of respective buttons 20 causes transmission of an associated code in a computer bound word to the computer which will direct the received code back to the terminal for illumination of the lamp associated with the actuated console button. Illumination of the button light indicates that the computer has received the information. Actuation of ENTER button 24 will cause entry of the previously transmitted interpretative data into the computer based medical record and will cause a terminal bound word command to be directed to the terminal for illumination of the Phrase ll button 26A for entry of subsequent interpretive data. Interpretive statements are similarly entered for Phrase Ill and Phrase IV. The phrases entered via console buttons 20 are stored in the patients medical record contained in computer memory. During readout of the interpretive data entered by the novel terminal, the computer under the government of appropriate software causes a narrative text to be printed in response to the stored interpretive statements.

In order to delete a phrase which has been previously entered, the phrase to be corrected is identified by ac- 6 tuation of the associated button 26A, which will cause transmission of a corresponding code to the computer. Upon receipt of this code word, the computer is operative to cancel information previously entered for the selected phrase. In this manner, data can be corrected in the patient record.

The invention is not to be limited by what has been particularly shown and described, except as indicated in the appended claims.
