Abstract

The invention is a precordial pad for positioning EKG electrodes on a patient for anatomically correct and repeatable placement. Data can be transmitted from the EKG pad of the invention by wire or wireless means. The pad includes a sizing aid, and a positioning device. The invention is also a system for obtaining and sending EKG data.

Claims

1. An EKG recording accessory system, which comprises:

a selection of disposable precordial pads in different sizes, said precordial pads with a plurality of electrodes, and with attached positioning devices, for use in accurately positioning said pad;

a universal adaptor/receiver which is compatible for connection to all EKG recording and monitoring machines, for receiving data from said electrodes and transferring data to an EKG machine and said precordial pad.

2. The EKG recording system of claim 1 in which said universal adaptor/receiver further includes capability to connect to non-EKG devices, including defibrillators, real time heart monitors, and external pacemakers.

3. The EKG recording accessory system of claim 1, in which said precordial pads of said system further include a temperature sensor in a pad body for measuring said patient'"'"'s skin temperature.

4. The EKG recording accessory system of claim 1, in which said universal adaptor/receiver of said system further includes a temperature reading window.

5. The EKG recording accessory system of claim 1 in which said universal adaptor/receiver of said system further includes a switch to select between wireless and hardwired operation.

6. The EKG recording accessory system of claim 1 in which said disposable precordial pads of said system comprise:

a pad body for conductive attachment to a patient'"'"'s torso, with a first and a second surface, with an adhesive surface on said body surface for contact with said patient'"'"'s skin;

a plurality of embedded electrodes in said pad body which extends from said pad body for electrical connection to the patient'"'"'s torso;

a data-transmitting module, for sending a plurality of signal from said embedded electrodes to an EKG machine;

a temperature sensor for sensing the temperature of said patient'"'"'s skin, and for sending temperature information to said EKG machine.

7. The EKG recording accessory system of claim 6 in which said data transmitting module is a wireless transmitter.

8. The EKG recording accessory system of claim 6 in which said data transmitting module is a wire cable with individual wires.

9. The EKG recording accessory system of claim 6 in which said plurality of electrodes includes one or more micro-transmitters for sending a signal from said electrode.

10. The EKG recording accessory system of claim 6 in which said disposable precordial pad further includes a circuit layer which is located between said first and said second layer, and which includes electronic connections between said electrodes and said data transmitting module.

11. The EKG recording accessory system of claim 10 in which said circuit layer is comprised of is comprised of an insulating sheet on which is placed electrical connections in the form of conductive pathways.

12. The EKG recording accessory system of claim 11 in which said conductive pathways are in the form of metallic ink circuitry.

13. The EKG recording accessory system of claim 6 in which said disposable precordial pads of the system further include an adhesive cover, which is removable for exposing said adhesive surface before use.

14. The EKG recording accessory system of claim 13 in which said embedded electrodes of said disposable precordial pads of the system include an electrode extension device, for causing said electrodes to extend beyond said adhesive surface when said adhesive cover is removed.

15. The precordial pad of claim 14 in which said electrode extension device is a biased member mounted between said embedded electrode and said pad, which is held in biased position by said adhesive cover, and which moves said electrode away from said pad when said adhesive cover is removed.

16. The EKG recording accessory system of claim 15 in which said electrode extension device is a spring or spring like device.

17. The EKG recording accessory system of claim 16 in which said electrode extension device member is a foam structure.

18. The EKG recording accessory system of claim 15 in which said embedded electrode is packaged under said adhesive cover with a layer of transmitting gel, in which said transmitting get and said embedded electrodes are exposed when said adhesive cover is removed.

19. The EKG recording accessory system of claim 6 which said disposable precordial pads of the system further includes six embedded electrodes in a predetermined geometry.
