Abstract

The present invention comprises a simple low cost remote cardiac resuscitation device, the patient'"'"'s portion of which is particularly adapted to be fitted into a "false bottom" briefcase or other hand carried article until needed. The device is compact, easily applied by the patient at the onset of a symptomatic attack, and will place at the command of an attending cardiologist all of the information which is required and the ability to provide primary resuscitative care to that patient via remote control pending the arrival of trained medical personnel.

Claims

1. A remote, telephonic, cardiac resuscitation apparatus comprising a portable, patient-operatable portion and a remote physician-operatable portion;

said patient operatable portion comprising;

(a) an acoustic telephone coupler;

(b) means associated with said coupler for treating said patient in response to coded tones received through said coupler;

(c) means for sensing a plurality of types of physiologic data indicating the cardiologic condition of said patient and for coding said data as a coded tone; and

(d) means responsive to a coded tone received from said acoustic coupler for selectively transmitting no more than one type of said coded data to said audio coupler.

2. The invention of claim 1 wherein said patient-operatable portion further comprises means for selectively, simultaneously transmitting the patient'"'"'s voice to said coupler.

3. The invention of claim 1 wherein said types of physiologic data further comprise the patient'"'"'s electrocardiogram.

4. The invention of claim 3 wherein said types of physiologic data comprise the patient'"'"'s pulse rate.

5. The invention of claim 3 wherein said types of physiologic data comprise the quality of defibrillator electrode contact with said patient.

6. The invention of claim 3 wherein said types of physiologic data further comprise the patient'"'"'s respiration rate.

7. The invention of claim 1 wherein said means associated with said coupler for treating said patient further comprises a defibrillator, and wherein said apparatus further comprises means for determining the operative state of said defibrillator with respect to said patient.

8. The invention of claim 7 wherein said apparatus further comprises means responsive to a coded tone received by said acoustic coupler for selectively transmitting to said coupler information reflecting said determination of the operability of said defibrillator.

9. The invention of claim 8 wherein said operability of said defibrillator is determined by means for sensing the degree of charge of said defibrillator.

10. The invention of claim 8 wherein the state of operability of said defibrillator is determined by means for sensing the quality of electrode contact with said patient.

11. The invention of claim 1 wherein each of said types of data collected by said apparatus is selectively coded by a voltage control oscillator into a single variable pitch.

12. The invention of claim 1 wherein said means for treating said patient comprises a drug injection.

13. The invention of claim 12 wherein said injection selectively injects predetermined aliquots of any of a plurality of drugs.

14. The invention of claim 13 wherein said injector comprises a syringe, means for reciprocating said syringe, a plurality of drug reservoirs, each selectively communicable through a conduit with said syringe, and a needle communicating with said conduit.

15. The invention of claim 14 wherein said means for reciprocating further comprises means for extending said needle into said patient.

16. The invention of claim 15 wherein said selective communication is through a single direction solenoid controlled valve.

17. The invention of claim 1 wherein said patient operatable portion further comprises a briefcase, said remainder of said apparatus portion being disposed below a false bottom thereof.

18. A remote, telephonic, cardiac resuscitation apparatus comprising a portable, patient-operatable portion and a remote physician-operatable portion, said physician operatable portion comprising:

(a) an acoustic telephone coupler;

(b) means for decoding physiological data received in the form of a variable pitch from said acoustic coupler;

(c) means for displaying said data to said physician; and

(d) means for transmitting coded tones to said acoustic coupler for selecting the physiologic data to be collected by said patient operatable portion, and for providing commands to said patient operatable portion to treat said patient.

19. The invention of claim 18 wherein said apparatus further comprises means for maintaining verbal communication between said physician to said patient during said transmission.

20. The invention of claim 18 wherein said apparatus further comprises means for selectively preventing verbal communication from said patient to said physician at least during said transmission of said physiologic data.

21. The invention of claim 18 wherein said apparatus further comprises sequencing means associated with said means for transmitting coded tones, said sequencing means cooperating with said decoding means to periodically collect and selectively display at least said physiologic data through said physician-operatable portion.

22. The invention of claim 21 wherein said sequencer controls the sequence with which particular coded tone commands will be transmitted to said acoustic coupler.

23. The invention of claim 22 wherein said apparatus further comprises a command sequence display associated with said sequencer for indicating the required command sequence.

24. The invention of claim 23 wherein said apparatus further comprises a timer, whereby the duration of a specific operation performed by said patient operatable apparatus may be selected by said physician.
