Abstract

The telephonic pacemaker monitoring device of the present invention eliminates the need for external electrodes that wrap around the fingers or wrists, or make contact with the skin on the chest. The monitoring unit has four finger touchpads and a communications station including a transmitter and a visual display located on the face of the device. The monitoring device also has a feedback system which enables the operator at the receiving center to immediately notify the patient via the visual display if a proper transmission or a faulty transmission is occurring. The feedback system and the visual display also enable the operator at the receiving center to notify the patient if increased finger pressure on the touchpads is needed or if the telephone handset should be picked-up for verbal communication. This feedback system and visual display eliminate the delay in notifying the patient that a faulty transmission has occurred. The present unit can also be used as a portable single channel telephonic EKG monitor which can be used by ambulances, paramedics, and other trained personnel at public gatherings.

Claims

1. A remote pacemaker monitoring device for a patient comprising a portable unit wherein at least three electrically conductive touchpads, a transmitter, an audio detector for detecting signals transmitted from a receiving center and a visual display are located on an outside surface of the unit;

wherein a detection and transmission circuit is electrically connected between the touchpads and the transmitter which is capable of detecting pacemaker signals and transmitting them to a receiving center via a communication means; and

wherein a decoder circuit is electrically connected between the visual display and the audio detector which is capable of providing visual feedback to the patient via the communication means for the receiving center.

2. The device as described in claim 1 wherein the communication means is a telephone system.

3. The device as described in claim 2 wherein the touchpads are located on the face of the unit in a U-shaped or V-shaped configuration.

4. The device as described in claim 3 further comprising a fourth touchpad and wherein two of the touchpads are electrically connected together to form a common reference.

5. The device as described in claim 4 wherein the visual display is located on the face of the unit.

6. The device as described in claim 5 wherein the transmitter comprises an output speaker.

7. The device as described in claim 6 further comprising a sound generating device for providing audio feedback to the patient which corresponds to the visual feedback.

8. The device as described in claim 6 further comprising a magnet and a magnet supporting device which adjustably located the magnet over the patient'"'"'s pacemaker causing it to operate in the magnetic mode.

9. The device as described in claim 8 wherein the magnet supporting device is a shoulder harness to which the magnet can be detachably connected by means of hook and loop fasteners.

10. The device as described in claim 6 further comprising a plurality of jacks for connecting external electrodes to the unit.

11. A remote cardiac monitoring device for a patient comprising a portable unit wherein at least three electrically conductive touchpads, a transmitter, an audio detector for detecting signals transmitted form a receiving center and a visual display are located on an outside surface of the unit;

wherein a detection and transmission circuit is electrically connected between the touchpads and the transmitter which is capable of detecting a patient'"'"'s pulse and transmitting it to a receiving center via a communication means; and

wherein a decoder circuit is electrically connected between the visual display and the audio detector which is capable of providing visual feedback to the patient via the communication means from the receiving center.

12. The device as described in claim 11 wherein the communication means is a telephone system.

13. The device as described in claim 12 wherein the touchpads are located on the face of the unit in a U-shaped or V-shaped configuration.

14. The device as described in claim 13 further comprising a fourth touchpad and wherein two of the touchpads are electrically connected together to form a common reference.

15. The device as described in claim 14 wherein the visual display is located on the face of the unit.

16. The device as described in claim 15 wherein the transmitter comprises and output speaker.

17. The device as described in claim 16 further comprising a sound generating device for providing audio feedback to the patient which corresponds to the visual feedback.

18. The device as described in claim 16 further comprising a plurality of jacks for connecting external electrodes to the unit.
