Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
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 having an upper and lower end, a first means on said flexible sheet for positioning the apparatus at its upper end at the clavicular notch and a second means on said sheet on the lower end for positioning the apparatus at the sternum notch, a plurality of electrically conductive metallic strips printed on said sheet, each strip 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 positioning the apparatus at the clavicular notch and at the sternum notch causes positioning of the conductive strips on or about the same position repeatedly.
Claim 2
Dependent Claim
150 words
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 having an upper and lower end, a first means on said flexible sheet for positioning the apparatus at its upper end at the clavicular notch and a second means on said sheet on the lower end for positioning the apparatus at the sternum notch, a plurality of electrically conductive metallic strips printed on said sheet, each strip 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 positioning the apparatus at the clavicular notch and at the sternum notch causes positioning of the conductive strips on or about the same position repeatedly.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1 wherein said strips comprise a copper alloy which is printed on said sheet.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1 wherein each strip comprises copper, silver, aluminum or alloys thereof.
Claim 5
Dependent Claim
166 words
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 having an upper and lower end, a first means on said flexible sheet for positioning the apparatus at its upper end at the clavicular notch and a second means on said sheet on the lower end for positioning the apparatus at the sternum notch, a plurality of electrically conductive wires mounted on said sheet, each 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, said wires comprising a metal selected from the group consisting of copper, silver, aluminum and alloys thereof, whereby positioning the apparatus at the clavicular notch and at the sternum notch causes positioning of the conductive wires on or about the same position repeatedly.
Claim 6
Dependent Claim
166 words
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 having an upper and lower end, a first means on said flexible sheet for positioning the apparatus at its upper end at the clavicular notch and a second means on said sheet on the lower end for positioning the apparatus at the sternum notch, a plurality of electrically conductive wires mounted on said sheet, each 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, said wires comprising a metal selected from the group consisting of copper, silver, aluminum and alloys thereof, whereby positioning the apparatus at the clavicular notch and at the sternum notch causes positioning of the conductive wires on or about the same position repeatedly.
