Abstract

An electrode patch used in tests of physical health conditions such as an electrocardiograph (ECG) electrode patch having marking means which leaves a position mark in the test site on a person being tested to permit accurate location of the site for accurate placement of electrode patches in subsequent tests in a series of test procedures on the site.

Claims

1. An electrocardiogram (ECG) electrode patch for use in electrocardiographic testing of a person'"'"'s heart condition,

said electrode patch including means for holding said patch over a selected test location on the body of a subject to be tested,

said electrode patch including means for marking said test location on the subject'"'"'s body where the patch is held during test,

said means for marking the test location being effective to leave a location mark for subsequent similar tests in said selected location upon removal of said patch following the test,

said electrode patch being circular in configuration,

said means for marking comprising a dye on the circumferential edge of said patch which leaves an arc-shaped mark in said test location corresponding to the curvature of the edge of said patch,

said arc-shaped mark being sufficiently long to permit matching of the edge of a circular patch of a subsequent test in exactly the same said test location,

said arc-shaped mark having an index mark associated therewith to indicate the number of the test conducted by said patch in a planned series of tests.

2. A method of conducting a series of electrocardiogram (ECG) tests in testing a subject for heart conditions comprising,

applying and securing an ECG electrode patch in a selected test location on the body of a subject to be tested,

leaving a location mark from said patch in said selected location after removal of a first said patch following a test, and

placing each successively applied patch in subsequent tests in said series in the same location in matched relation to said mark.

3. A method as set forth in claim 2 including matching another ECG patch to said location mark in a subsequent test conducted in said series to assure placement of said other patch in the same test location as said first patch.

4. A method of conducting a series of electrocardiogram (ECG) tests as set forth in claim 2 in which the electrode patches used are circular and the mark left in said selected location is an arc imprinted on the site by a dye conforming in shape and provided at the edge of at least said first circular patch.

5. A method of conducting a series of electrocardiogram (ECG) tests as set forth in claim 4 including providing an index mark in association with said arc-shaped location mark for rotationally indexing of subsequent patches to indicate the number of tests conducted in a series.

6. A method of conducting a series of electrocardiogram (ECG) tests as set forth in claim 5 including providing a reference mark on the exposed surface of said patch to facilitate matching said reference mark to a preceding index mark on said subject for rotational indexing of said patch in relation to the rotational position of preceding patches in a series of tests conducted.

7. An electrode patch for test measuring the physical condition of a patient,

said electrode patch including means for holding said patch over a selected test site on the body of a subject to be tested,

said electrode patch including means for marking said test site on the subject'"'"'s body where the patch is held during test,

said means for marking the test site being effective to leave a location mark in said selected site after removal of said patch following a test,

said electrode patch comprising one of a series of individual electrode patches for testing the physical condition of said patient in said selected test location on the body of the patient,

whereby each of said series of electrode patches in turn can be matched to said location mark to place each patch in said series in identically the same test location,

each said patch in said series being arranged to leave a mark in said test site separate from previous marks for indication of the number of tests completed.

8. A series of electrode patches as set forth in claim 7 in which each patch in said series is arranged to leave a mark of different color from the mark of the preceding patch in said series.

9. An electrode patch as set forth in claim 7 in which said marking means is a dye transferrable to the skin of said subject during testing.

10. An electrode patch as set forth in claim 9 in which said marking dye transferred to the subject is not water washable but is removable with alcohol.

11. An electrode patch as set forth in claim 7 in which said means for holding said patch over said test site is in the form of a suction-cup to which marking means is applied.

12. A method of measuring a physical condition of a patient in a selected test site with a series of electrode patches to be used in said selected test site,

holding each of said series of patches over said selected test site each in turn for a predetermined test period,

leaving a location mark at said test site with at least the first patch of said series, and

placing each patch of said series after said first patch in matched relation with said location mark to thereby place each patch of said series in identically the same test site during said series of tests.

13. A method as set forth in claim 12 including transferring from each patch after said first patch a reference mark which indicates that the test with each said respective patch in said series had been conducted.
