Description

FIELD OF THE DISCLOSURE

The present disclosure relates generally to an electrode patch that may be used with health monitoring device.

BACKGROUND

In the EKG industry, the single electrode or patch is popular for patient comfort. However, at least half of the time, a single patch/electrode design cannot be used on different body types and sizes, for example between a male and a female. In that case, individual electrodes are necessary. What is needed is a convertible or adjustable electrode (patch) design that allows the medical technician or physician to have the advantages of the single electrode design, but also allows the physician to convert the electrode (patch) into as many individual electrodes as necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In electrocardiography, the word “lead” may refer to either the electrodes attached to the patient, or, properly, to the voltage or signal measured between two electrodes. To avoid confusion, “channel” is used to describe the voltage, signal or view from a positive electrode to a negative electrode across the heart.

Referring now to FIG. 1A, an electrode patch 10 is shown having a patch body 12. The patch body 12 can be in various shapes and sizes. There are electrodes connected to the patch body. In the embodiment shown, there is a negative electrode 14 on a first portion 16 of the patch body, a ground electrode 18 on a second portion 20 of the patch body, and a positive electrode 22 on a third portion of the patch body. Perforations 26 are also on the patch body 12 in order to tear and remove one portion of the patch body. The perforations 26 may be located anywhere in between the individual electrodes. In one embodiment the perforations set the boundaries for the first, second and third portions of the patch body. In other embodiments, the electrode patch may be separated into distinct portions by other methods including cutting or tearing the patch body itself Also, in other embodiments, additional electrodes may be included on the patch body and the number of perforations may increase depending on the number of electrodes. As shown in FIG. 1A, the electrode patch 10 is intact.

In use, the electrode patch 10 may be used with a cardiac monitoring device and placed on a patient for observation. One embodiment of the electrode patch 10 is designed to maximize patient comfort while improving patient compliance. One embodiment of the electrode patch is a combination of an EKG patch (multiple electrodes housed in one shape or body) and when necessary, a separated or “spider” design can be converted into multiple individual electrodes.

An embodiment of the electrode patch 10 detached to accommodate a location for a negative electrode 14 is shown in FIG. 1B. As shown, one perforation 26 has been torn separating the first portion 16 from the other portions of the electrode patch body 12. In this way, the negative electrode may be placed in a more desired location on the body of a patient that is away from the other electrodes of the patch. In this way, the electrode patch is adjustable to the size and shape of the body of the patient.

An embodiment of the electrode patch 10 detached to accommodate a location for a positive electrode 22 is shown in FIG. 1C. As shown, one perforation 26 has been torn separating the third portion 24 from the other portions of the electrode patch body 12. In this way, the positive electrode may be placed in a more desired location on the body of a patient that is away from the other electrodes of the patch. In this way, the electrode patch is adjustable to the size and shape of the body of the patient.

An embodiment of the electrode patch 10 completely detached at each perforation 26 is shown in FIG. 1D. As shown, both perforations 26 have been torn separating the first, second, and third portions 16, 20, and 24 from one another. In this way, each negative electrode may be placed in a more desired location on the body of a patient that is away from the other electrodes of the patch. In this way, the electrode patch is adjustable to the size and shape of the body of the patient and is not restricted to the size of the electrode patch when it is intact.

FIG. 2 depicts a bottom side of the electrode patch 10 shown in FIG. 1A. The bottom side will come into contact with the patient body. There may be an electrode conductive gel 28 covering the bottom side of the electrodes on the patch to create electrical skin contact. In addition, there may be an adhesive (not shown) on the bottom side of the patch body 12 in order for the patch to attach to the body of the patient.

The electrode patch 10 shown in the figures allows a medical technician or physician to have the advantages of the single electrode design, but allows the technician or physician to convert the single patch/electrode design into as many individual electrodes as necessary depending on the body-type of the patient. This allows the technician or physician to get the necessary EKG information from a single patch design as shown. As shown, one embodiment of electrode patch 10 is for two leads of EKG. However, the perforated electrode patch can be designed to provide anywhere from one EKG lead to 12 EKG leads, depending upon which EKG tests are necessary. And in any test case, if the individual one piece design does not conform to the body of the patient, the electrode patch 10 can convert to separate electrodes and can be applied wherever on the body it is necessary to get the EKG from that patient. This design insures that a patient's EKG hookup can occur regardless of the body size and or condition of the patient's body and further insure maximum patient comfort and compliance. This design of the electrode patch 10 allows for maximum use of multiple leads, whereas other patch products do not provide for multiple EKG leads vectors.

As shown in FIG. 3, the electrodes 14, 18, and 22 of the electrode patch 10 are connected to leads 30 that are connected to a cardiac monitoring device 32. As shown, the cardiac monitoring device 32 may be a portable or wearable cardiac monitoring device. In other embodiments, the electrodes of the electrode patch 10 may be connected to any cardiac monitoring device. In use, the patch 10 may be left intact as shown in FIG. 3 and secured to the body of the patient.

If necessary, the electrode patch 10 may be converted from the single patch configuration to the separated configuration, where the first, second and third portions have all been separated from one another as shown in FIG. 4. After tearing the patch body 12 at the perforations 26, the separated portions may then be secured to the body of the patient in various locations in order to collect EKG information. In one embodiment, the adhesive material between perforations on the bottom side of the patch body may be utilized to hold in place the EKG lead-wires 30. In use, the leads 30 are looped under the portions of the patch body to form stress loops as shown in FIG. 4 when the patch is secured to the body. In this way, the lead-wires remain in place.
