Abstract

The invention relates to an electrodeless device for administering an electrocardiogram consisting essentially of a single flexible sheet having multiple electrical strips or wires pre-positioned for placement on a patient'"'"'s chest. The device includes at least two positioning means.

Claims

1. An electrodeless apparatus for wearing by a patient about the chest area for transmitting electrical impulses from the patient to an electrocardiograph, consisting essentially of a flexible non-conductive sheet, a plurality of electrically conductive strips or wires mounted on said sheet, each strip or wire having a first end adapted for electrical connection with the skin of the patient for receiving and transmitting electrical impulses, and a second end adapted for connection with a terminal for transmitting electrical impulses to an electrocardiograph device, whereby electrical impulses are transmitted through said strip or wire without an electrode, and wherein

each said strip or wire comprises copper, silver, aluminum or alloys thereof.

2. An electrode apparatus according to claim 1, wherein each said strip or wire is printed or silk-screened on said non-conductive sheet.

3. An electrodeless apparatus for wearing by a patient about the chest area for transmitting electrical impulses from the patient to an electrocardiograph, consisting essentially of a flexible non-conductive sheet, a plurality of electrically conductive strips or wires disposed on said sheet, each strip or wire having a first end adapted for electrical connection with the skin of the patient for receiving and transmitting electrical impulses, and a second end adapted for connection with a terminal for transmitting electrical impulses to an electrocardiograph device, whereby electrical impulses are transmitted through said strip or wire without an electrode, and wherein

each said strip or wire is comprised of a metallic material.

4. An electrode apparatus according to claim 3, wherein each said strip or wire is printed or silk-screened on said non-conductive sheet.

5. An electrodeless apparatus for wearing by a patient about the chest area for transmitting electrical impulses from the patient to an electrocardiograph, consisting essentially of a flexible non-conductive sheet, a plurality of electrically conductive strips or wires disposed on said sheet, each strip or wire having a first end adapted for electrical connection with the skin of the patient for receiving and transmitting electrical impulses, and a second end adapted for connection with a terminal for transmitting electrical impulses to an electrocardiograph device, whereby electrical impulses are transmitted through said strip or wire without an electrode, and wherein

each said strip or wire is comprised of a polymer material.

6. An electrode apparatus according to claim 5, wherein each said strip or wire is heat pressed on said non-conductive sheet.

7. An electrodeless apparatus for wearing by a patient about the chest area for transmitting electrical impulses from the patient to an electrocardiograph, consisting essentially of a flexible non-conductive sheet, a plurality of electrically conductive strips or wires disposed on said sheet, each strip or wire having a first end adapted for electrical connection with the skin of the patient for receiving and transmitting electrical impulses, and a second end adapted for connection with a terminal for transmitting electrical impulses to an electrocardiograph device, whereby electrical impulses are transmitted through said strip or wire without an electrode, and wherein

each said strip or wire is comprised of a conductive paste.

8. An electrode apparatus according to claim 7, wherein each said strip or wire is printed or silk-screened on said non-conductive sheet.
