Abstract

A system for monitoring vital signs of a live body includes an inquiring device; and a portable monitoring device. The monitoring device includes an electrical circuit, which, in turn, includes a controller, data storage, and input ports. The electrical circuit is designed to read inputs and store data. The monitoring device further includes a number of sensors which are connected to the electrical circuit, each of the sensors detecting a property of the body. The device also includes an alarm mechanism which is designed to activate when a predetermined set point stored in the data storage is exceeded. The device further includes a mechanism for transferring stored data or received inputs to the inquiring device, further allowing the downloading of data and the setting or changing of one or more set-points of said alarm mechanism. Finally, the monitoring device includes a housing for holding the electrical circuit and sensors, as well as the communication means, the alarm device and the power supply.

Claims

1. A system for monitoring vital signs of a live body, comprising:

(a) an inquiring device;

(b) a portable monitoring device, said device including;

(i) an electrical circuit, said circuit including a controller, data storage capability, and input ports, said electrical circuit being designed to read inputs and to store data;

(ii) a plurality of sensors connected to said electrical circuit inputs, each of said sensors providing said sensor'"'"'s corresponding sensor output;

(iii) an alarm mechanism, said alarm mechanism designed to activate when a predetermined set point stored in said data storage capability is exceeded, said set point being based on at least one of said sensor outputs;

(iv) communication means for transferring said data to said inquiring device, and for downloading of related data such as personal identification parameters, operating software, forced measurement software, and alarm set-points from said inquiring device; and

,

(v) an instruction set for operation of said portable monitoring device.

2. A system as in claim 1, wherein said transferring of said data to said inquiring device occurs on-line.

3. A system as in claim 1, further comprising a housing, wherein said housing includes a plurality of electrodes on which at least one of said sensors is mounted.

4. A system as in claim 1, wherein said electrical circuit further includes a sensor switching coupling element which alternately connects and disconnects sensors.

5. A system as in claim 4, in which said sensor switching coupling element alternately connects and disconnects sensors which may interfere with each other.

6. A system as in claim 1, wherein said transferring of said data to said inquiring device and downloading of related data from said inquiring device is effected using optical impulses.

7. A system as in claim 1, wherein said transferring of said data to said inquiring device and downloading of related data from said inquiring device is effected using electronic wireless transmission.

8. A system as in claim 1 wherein said monitoring device is attached to the body using an adhesive layer.

9. A system as in claim 1, further comprising a database stored in said inquiring device, said database including symptoms and diagnoses for diagnosing the live body, based on said inputs from said sensors.

10. A system as in claim 9, further comprising a display for displaying said diagnoses.

11. A system as in claim 1, further including a display for displaying said inputs from said sensors.

12. A system as in claim 1, wherein said alarm set point is defined by a combination of said sensor outputs, each of which individual said sensor outputs is insufficient to exceed said sensor output'"'"'s corresponding alarm set point.

13. A device as in claim 1, further comprising

(c) GPS position locating capability.

14. A method for monitoring vital signs of a live body, comprising

(a) providing:

(1) an inquiring device; and

,

(2) a portable monitoring device, said device including;

(i) an electrical circuit, said circuit including a controller, data storage capability, and input ports, said electrical circuit being designed to read inputs and to store data;

(ii) a plurality of sensors connected to said electrical circuit inputs, each of said sensors providing said sensor'"'"'s corresponding sensor output;

(iii) an alarm mechanism, said alarm mechanism designed to activate when a predetermined set point stored in said data storage capability is exceeded, said set point being based on at least one of said sensor outputs;

(iv) communication means for transferring said data to said inquiring device, and for downloading of related data such as personal identification parameters, operating software, forced measurement software, and alarm set-points from said inquiring device; and

,

(b) providing said operating software to said inquiring and portable monitoring devices;

(c) providing diagnostic software and said alarm set-points to said inquiring device;

(1) monitoring of said measured parameters of said live body; and

,

(2) comparing of said measured parameters with said set-points, thereby providing warning alarm capability if said measured parameters exceed said set-points.

15. A method as in claim 14, further comprising providing a database stored in said inquiring device, said database including symptoms and diagnoses for diagnosing the live body, based on said inputs from said sensors.

16. A method as in claim 15, further comprising providing software using said data and said database to provide capability of displaying any of:

said sensor outputs, said alarm set-points, said alarm indicator status, said personal identification parameters, histograms of accumulated data, current diagnosis of state of health of the live body, possible reasons for abnormal physical data, possible reasons for abnormal diagnosis based on physical data, suggested treatment in case of abnormal diagnosis, anticipated behaviour of the body due to said suggested treatment, and monitoring physical changes resulting from actual treatment.

18. A method as in claim 14, further comprising

(g) (1) providing GPS patient position locating capability;

and,

(2) transmitting patient location to said inquiring system.

17. A method as in 14, further comprising transmitting said measured data to said inquiring device for more detailed diagnosis.
