Abstract

Method and system for remote monitoring of high-risk patients using artificial intelligence. A plurality of high-risk patients can be simultaneously monitored without patient intervention. A patient hears questions in the doctor'"'"'s voice at each monitoring encounter and responds. The patient'"'"'s responses are recorded at a remote central monitoring station and can be analyzed on line or later. Artificial intelligence (AI) and voice technology (DECvoice) are combined to present to the patient, during a monitoring session or encounter, questions which would be selected from a plurality of different recorded questions. Questions to the patient are chosen using AI, based on the patient'"'"'s response, by parsing. The monitor could take several forms such as for e.g., uterine activity strips, glucometers, blood pressure cuffs, pulse monitors, electroencephalographs, etc. Preferably, four telephone lines are dedicated to each patient, one for the monitor, one for the voice, one as a back up and one to sense failures. Dual tone matrix frequency signals (DTMF) may be used for transmission of monitored signals and other information which can be recognized by DECvoice, which is but one example of the voice technology which can be used.

Claims

1. A method of remote monitoring at least one patient by using a telephone and artificial intelligence through a monitoring device which is used by the patient, without the patient having to read the monitoring device, comprising the steps of:

recording patient information including patient data, medical history and other considerations relevant to treatment of the patient concerned;

generating several questions which could be asked of the patient by an attending physician and which questions are of the physician'"'"'s own choice;

creating a telephone monitoring encounter with the patient to be monitored in the doctor'"'"'s own voice without the use of a modem;

using artificial intelligence (AI) for parsing said several questions to create a selection and sequence of selected questions chosen by AI from said several questions based on progressive patient response;

at the end of said sequence of selected questions, obtaining a reading signal from the monitoring device through telephone lines without a modem and by using a telephone cord splitter;

and applying physician laid down criteria for evaluating said progressive patient response and the obtained reading signal to determine any course of action necessary.

2. A method as recited in claim 1 wherein the step of obtaining a reading signal from the monitoring device comprises using dual tone matrix frequency signals.

3. A method as recited in claim 1 including the steps of using computer integrated telephony and comparing said signal from said monitoring device with physician laid down criteria, and initiating suitable intervention and action for a monitored patient.

4. A method as recited in claim 1 wherein said step of creating a telephone monitoring encounter comprises using a voice transmission means which recognizes, receives and transmits voice.

7. A system as recited in claim 1 including computer integrated telephony to receive said patient'"'"'s response and said signals from said monitoring device.

9. A system as recited in claim 7 including a voice transmission means which has capabilities of recognizing, receiving and transmitting voice, and includes memory.

5. A system for remote monitoring of at least one patient by using telephone lines and artificial intelligence, through a monitoring device which is used by the patient, without the patient having to read the monitoring device, said system comprising:

recorded patient information including patient data, medical history and other considerations relevant to treatment of the patient concerned;

a plurality of physician generated questions recorded in the voice of the patient'"'"'s physician, which questions could be selectively asked of the patient in the physician'"'"'s voice using voice technology through telephone lines without a modem;

a programmed read-only memory which is programmed using artificial intelligence to select applicable questions and to parse said selected questions in a sequence from said physician generated questions, based on the patient'"'"'s response; and

means without a modem for obtaining and transmitting signals from said monitoring device over telephone lines to a computer integrated telephone system, wherein by comparison of the transmitted signals with criteria predetermined by the physician, suitable intervention and action can be initiated.

6. A system as recited in claim 5 wherein said means for obtaining and transmitting signals includes a telephone cord splitter and means for encoding said obtained signals from said monitoring device into dual tone matrix frequency signals.

8. A system as recited in claim 6 including a voice transmission means which has capabilities of recognizing, receiving and transmitting voice and includes memory.

10. In a method of remote monitoring of at least one patient by a physician through a monitoring device which is used by the patient, without the patient having to read the monitoring device, the improvement comprising:

recording patient information including patient data, medical history and other considerations determined by an attending physician to be relevant to treatment of a concerned patient;

recording physician generated questions in the physician'"'"'s own voice, which generated questions could be selectively asked of a patient being monitored;

using voice-technology and creating a telephone monitoring encounter with said patient to be monitored directly through telephone lines without a modem to present to said patient selected ones of said physician generated questions;

using artificial intelligence (AI) for parsing said several questions to create a selection of parsed questions based on progressive patient response;

obtaining a reading signal from said monitoring device using telephone lines without a modem but using a telephone cord splitter; and

applying physician'"'"'s predetermined criteria for evaluating said progressive patient response and the obtained reading signal and concurrently determing any course of action to be taken by said physician.

11. A method as in claim 10 wherein the step of obtaining a reading signal from said monitoring device comprises using dual tone matrix frequency signals.

12. A method as in claim 10 wherein the step of using voice technology and creating a telephone monitoring encounter comprises using a voice transmission means which has capabilities of recognizing, receiving and transmitting voice, and includes memory.
