Abstract

An electrode system for use in administering an EKG test, provided as a chair with a flexible strap having electrodes embedded therein. The flexible strap is attached to the chair back rest and is tightened around the chest when the patient is seated in the chair. Electrodes fitted in the lower portion of the chair and the armrest make connection, respectively, to the legs and arms, thereby completing the test set-up procedure in a short time period. The electrodes embedded in the flexible strap are adjustable horizontally, and the strap itself is adjustable vertically, so that particular locations on the chest are reachable, making the strap suitable for all size patients. The chair is designed to become a bed to increase patient comfort. A set of exercise accessories is removably attachable to the chair, to permit EKG measurements during physical exertion. The electrode system has many applications, in hospitals, clinics, emergency rooms, intensive care units, cardiology units, health institutes, old age homes, and sports medicine clinics.

Claims

1. An electrode system for reducing the set-up time for electrode placement on parts of the body in medical diagnostic testing (EKG) comprising in combination:

support structure means for supporting the body;

a first plurality of electrodes supported by said support structure means, wherein said support structure means is a chair for seating the body, and said first plurality of electrodes is enclosed in a flexible strap attached at one end thereof to said chair, for placement of said flexible strap across the chest; and

a second plurality of electrodes each fixedly mounted at a location on said chair for contacting the arms and legs,

such that when the body is supported by said chair, said first and second plurality of electrodes contact the body and enable rapid electrical connection thereto for diagnostic testing,

wherein said flexible strap comprises layers of flexible material formed with slots therein, each of said slots having a contact being movable therein in adjustable fashion, said strap being vertically adjustable, enabling said contact to be placed in an optimal location against the body.

2. The electrode system of claim 1 wherein said chair comprises a seat and seat back pivotably attached thereto, and a foot rest pivotably attached to said seat, said seat back and foot rest being adjustable into seated and reclining positions.

3. The electrode system of claim 1 wherein each of said second plurality of electrodes comprises a base containing an absorbent pad disposed under an electrically-conductive surface having holes formed therein, said pad containing an electrically-conductive liquid, to insure good contact with the skin.

4. The electrode system of claim 1 wherein said support structure means is provided with a cable receptacle connected to said electrodes enabling connection via a multi-wire cable to an EKG machine.

5. The electrode system of claim 1 further comprising an exerciser means having additional, alternative ones of said second plurality of electrodes mounted thereon, said exerciser means being removably attachable to said support structure means for enabling exercising of at least one of the arms and legs, providing stress conditions for testing.

6. The electrode system of claim 1 for use with self-administered diagnostic testing apparatus, said testing apparatus comprising a communication terminal mounted on said support structure means, said communication terminal automatically feeding a set of diagnostic test results to a central clinic.

7. The electrode system of claim 1 wherein said support structure means is a bed and further comprising a set of quick-release clamps, wherein said first plurality of electrodes enclosed in said flexible strap is removably attached at one end thereof to said bed by said quick-release clamps, and said second plurality of electrodes are each attached to said bed in removable fashion by said quick-release clamps.

8. The electrode system of claim 1 wherein said first plurality of electrodes comprises defibrillator electrodes.

9. The electrode system of claim 1 further comprising an echo transducer mounted in said flexible strap for performing echocardiograph tests.

10. A method for reducing the set-up time for placement of electrodes on parts of the body in medical diagnostic testing (EKG) comprising the steps of:

providing a support structure means for supporting the body, having a first plurality of electrodes supported by said support structure means, said first plurality of electrodes being enclosed in a flexible strap attached at one end thereof to said support structure means, for placement of said flexible strap across the chest, and a second plurality of electrodes each fixedly mounted at a location on said support structure means for contacting the arms and legs; and

supporting the body by said support structure means, such that said first and second plurality of electrodes contact the body and enable rapid electrical connection thereto for diagnostic testing,

wherein said flexible strap comprises layers of flexible material formed with slots therein, each of said slots having a contact being movable therein in adjustable fashion, said strap being vertically adjustable, enabling said contact to be placed in an optimal location against the body.

11. The method of claim 10 further comprising the step of providing a self-administered diagnostic testing apparatus comprising a communication terminal mounted on said support structure means, and further comprising the step of performing the diagnostic test and obtaining a set of diagnostic test results, which are fed automatically to a central clinic via said communication terminal.

12. The method of claim 10 further comprising the step of attaching exerciser means to said support structure means for exercising at least one of the arms and legs while performing the test, to obtain complete EKG test results under stress conditions, said exerciser means having additional, alternative ones of said second plurality of electrodes mounted thereon.

13. The method of claim 10 wherein said support structure means is a chair for seating the body.

14. The method of claim 13 further comprising the step of attaching exerciser means to said support structure means for enabling exercising of at least one of the arms and legs, providing stress conditions for testing, said exerciser means having additional, alternative ones of said second plurality of electrodes mounted thereon, and

providing an echo transducer retained in position within said flexible strap to contact the body and allow echocardiograph testing under said stress conditions.

15. The method of claim 10 wherein the step of providing a supporting structure comprises providing a bed upon which the body lies, and further comprising a set of quick-release clamps, wherein said first plurality of electrodes enclosed in said flexible strap is removably attached at one end thereof to said bed by said quick-release clamps, for placement of said flexible strap across the chest, said second plurality of electrodes being mounted on said bed in removable fashion by said quick-release clamps for contacting the arms and legs.

16. The method of claim 10 wherein said first plurality of electrodes comprises defibrillator contacts for use in a defibrillation treatment to administer electrical shock quickly.

17. An electrode system for reducing the set-up time for electrode placement on parts of the body in medical diagnostic testing (EKG) comprising in combination:

support structure means for supporting the body;

a first plurality of electrodes supported by said support structure means, wherein said first plurality of electrodes is enclosed in a flexible strap attached at one end thereof to said support structure means, for placement of said flexible strap across the chest, said flexible strap comprising layers of flexible material formed with slots therein, each of said slots having a contact being movable therein in adjustable fashion, said strap being vertically adjustable, enabling said contact to be placed in an optimal location; and

a second plurality of electrodes each fixedly mounted at a location on said support structure means, said second plurality of electrodes being mounted for contacting the arms and legs

such that when the body is supported by said support structure means, said first and second plurality of electrodes contact the body and enable rapid electrical connection thereto for diagnostic testing.

18. The electrode system of claim 17 wherein said support structure means is a chair for seating the body.
