Abstract

A medical method comprises the steps of scanning a predetermined internal organ of a patient to collect individualized dimensional data about the organ, digitizing the data, and automatically storing encoded structural dimensions of the organ at different times. Dimensions of the organ are automatically compared with previously stored dimensions to determine changes in the dimensions. A cognizable signal is automatically generated, at a remote facility or at the person of the patient, upon a determination that dimensions of the organ have changed so as to indicate a dangerous condition of the patient, such as a ruptured splenic hematoma or a ruptured aneurysm.

Claims

1. A medical method comprising the steps of:

scanning a predetermined internal organ of a patient;

storing dimensional data obtained during said step of scanning and relating to dimensions of said organ;

automatically comparing the dimensional data obtained during said step of scanning with stored previously determined data relating to dimensions said organ; and

upon determining in said step of comparing that said organ has undergone a change in its dimensions indicating a possibly dangerous condition of the patient, automatically treating the patient therapeutically to alleviate the possibly dangerous condition.

2. The method defined in claim 1 wherein said step of therapeutically affecting includes the step of at least reducing blood flow to the organ.

3. The method defined in claim 2 wherein said step of reducing includes the step of inflating a balloon in an artery feeding the organ to thereby block blood flow in said artery.

4. The method defined in claim 1 wherein said step of generating includes the steps of connecting a transmitter device to a modem and transmitting an electromagnetic signal over telephone lines to a remote monitoring facility.

5. The method defined in claim 4 wherein said electromagnetic signal is a wireless signal, said step of transmitting includes the step of wirelessly transmitting said wireless signal.

6. The method defined in claim 1, further comprising the step of attaching a scanning device to the patient.

7. The method defined in claim 1, further comprising the steps of (a) transmitting the dimensional data to a remote monitoring facility, (b) receiving instructions from said facility, and (c) manually moving a scanning device from one location to another in response to said instructions, each such location being juxtaposed to the patient.

8. The method defined in claim 1 wherein said step of scanning includes the steps of generating an ultrasonic pressure wave, monitoring said pressure wave upon reflection thereof by internal organs, and generating an electrical signal encoding the reflected ultrasonic pressure wave.

9. The method defined in claim 1 wherein said step of scanning includes the step of detecting byproducts of radioactive decay.

10. The method defined in claim 1 wherein the organ is a spleen.

11. The method defined in claim 1 wherein the organ is a blood vessel.

12. The method defined in claim 1, further comprising the step of automatically generating a cognizable signal upon determining in said step of comparing that said organ has undergone said change in its dimensions.

13. The method defined in claim 1 wherein said step of affecting includes the step of operating a device at least partially inserted into the patient.

14. A medical method comprising the steps of:

attaching a scanning device to a patient;

operating said scanning device to scan a predetermined internal organ of the patient;

storing dimensional data obtained during said step of scanning and relating to dimensions of said organ;

automatically comparing the dimensional data obtained during said step of scanning with stored previously determined data relating to dimensions of said organ so as to determine whether said organ has undergone a change in its dimensions indicating a possibly dangerous condition of the patient; and

upon determining in said step of comparing that said organ has undergone said change in its dimensions, automatically generating a cognizable signal.

15. The method defined in claim 14 wherein said step of generating includes the step of transmitting an electromagnetic signal to a remote monitoring facility.

16. The method defined in claim 14, further comprising the steps of (a) transmitting the dimensional data to a remote monitoring facility, (b) receiving instructions from said facility, and (c) manually moving said scanning device from one location to another in response to said instructions, each such location being juxtaposed to the patient.

17. The method defined in claim 14 wherein said step of scanning includes the step of detecting byproducts of radioactive decay.

18. The method defined in claim 14 wherein the dimensional data relates to external dimensions of said organ.

19. A medical system comprising:

scanning means juxtaposable to a patient for collecting individualized dimensional data about a predetermined internal organ of the patient;

memory means operatively connected to said scanning means for storing the dimensional data obtained by said scanning means at different times;

computing means operatively connected to said memory means for comparing the dimensional data obtained at one time with the dimensional data obtained at a subsequent time so as to determine whether said organ has undergone a change in its dimensions indicating a possibly dangerous condition of the patient; and

treatment means operatively connected to said computing means and adapted for at least partial implantation into the patient for therapeutically affecting the patient to alleviate the possibly dangerous condition upon the determination by said computing means that said organ has undergone a change in its dimensions indicating said possibly dangerous condition.

20. The system defined in claim 19 wherein said treatment means includes means for at least reducing blood flow to the organ upon the determination by said computing means that the organ has undergone a change in its dimensions indicating said possibly dangerous condition.

21. The system defined in claim 20 wherein said means for reducing includes a balloon disposable in an artery feeding the organ and inflation means operatively connected to said balloon for inflating said balloon for blocking blood flow in said artery upon the determination by said computing means that dimensions of the organ have changed so as to indicate a possibly dangerous condition.

22. The system defined in claim 19 wherein said scanning means is portable, further comprising fastener means for attaching said scanning means to the patient.

23. The system defined in claim 19 wherein said scanning means includes electroacoustic transducer means for generating an ultrasonic pressure wave and acoustoelectric transducer means for generating an electrical signal encoding reflected ultrasonic pressure waves received by said scanning means.

24. The system defined in claim 19 wherein said scanning means includes detector means for detecting byproducts of radioactive decay.

25. The system defined in claim 19, further comprising alarm means operatively connected to said computing means for generating a cognizable signal upon a determination by said computing means that dimensions of the organ have changed so as to indicate a possibly dangerous condition of the patient.

26. The system defined in claim 25 wherein said alarm means includes transmitter means for transmitting to a remote monitoring facility an electromagnetic signal encoding the change in dimensions of the organ.

27. The system defined in claim 26 wherein said electromagnetic signal is a wireless signal, said transmitter means including means for generating and transmitting said wireless signal.

28. A medical method comprising the steps of:

scanning a predetermined internal organ of a patient to determine external dimensions of said organ as defined between outwardly facing surfaces of said organ;
