Abstract

Claims (22)

1. A monitor for a subject, comprising:

circuitry configured to receive and process at least first and second signals to monitor at least one characteristic of the subject;

a flexible polymer casing extending around the circuitry to form a waterproof enclosure for the circuitry, wherein the flexible polymer casing is infused with a conductive material at at least first and second locations that are spaced apart on a first side of the flexible polymer casing to form at least first and second infused electrodes that extend from an exterior of the flexible polymer casing to an interior of the flexible polymer casing, wherein the first infused electrode is coupled to the circuitry so as to allow the first signal to pass from outside the flexible polymer casing to the circuitry, and the second infused electrode is coupled to the circuitry so as to allow the second signal to pass from outside the flexible polymer casing to the circuitry, and wherein at least one first polymer chain in a first portion of the flexible polymer casing that is infused with the conductive material at the first location is cross-linked with at least one second polymer chain in a second portion of the flexible polymer casing that is not infused with the conductive material; and

an electrode strip attachable to the first side of the flexible polymer casing, the electrode strip comprising monitor electrodes configured and arranged to establish conductive paths between the first and second infused electrodes and respective third and fourth locations on a surface of skin of the subject.

2. The monitor of claim 1 , wherein the flexible polymer casing comprises silicone.

3. The monitor of claim 2 , wherein the conductive material comprises carbon.

4. The monitor of claim 1 , wherein the conductive material comprises carbon.

5. The monitor of claim 1 , wherein the circuitry is configured to process the first and second signals from the first and second infused electrodes to monitor a cardiac characteristic of the subject.

6. The monitor of claim 1 , wherein the electrode strip comprises an adhesive layer disposed on each of two sides so that one side can be releasably adhered to the first side of the flexible polymer casing and the other side can be releasably adhered to the skin of the subject.

7. The monitor of claim 1 , wherein the circuitry comprises a digital processor and a battery.

8. The monitor of claim 1 , wherein at least one third polymer chain in a third portion of the flexible polymer casing that is infused with the conductive material at the second location is cross-linked with at least one fourth polymer chain in a fourth portion of the flexible polymer casing that is not infused with the conductive material.

9. A monitor for a subject, comprising:

circuitry configured to receive and process at least first and second signals to monitor at least one characteristic of the subject;

a flexible waterproof enclosure for the circuitry that is infused with a conductive material at at least first and second locations that are spaced apart on a first side of the flexible waterproof enclosure to form at least first and second infused electrodes that extend from an exterior of the flexible waterproof enclosure to an interior of the flexible waterproof enclosure, wherein the first infused electrode is coupled to the circuitry so as to allow the first signal to pass from outside the flexible waterproof enclosure to the circuitry, and the second infused electrode is coupled to the circuitry so as to allow the second signal to pass from outside the flexible waterproof enclosure to the circuitry, and wherein at least one first polymer chain in a first portion of the flexible waterproof enclosure that is infused with the conductive material at the first location is cross-linked with at least one second polymer chain in a second portion of the flexible waterproof enclosure that is not infused with the conductive material; and

an electrode strip attachable to the first side of the flexible waterproof enclosure, the electrode strip comprising monitor electrodes configured and arranged to establish conductive paths between the first and second infused electrodes and respective third and fourth locations on a surface of skin of the subject.

10. The monitor of claim 9 , wherein the circuitry is configured to process the first and second signals from the first and second infused electrodes to monitor a cardiac characteristic of the subject.

11. The monitor of claim 9 , wherein the flexible waterproof enclosure comprises silicone.

12. The monitor of claim 11 , wherein the conductive material comprises carbon.

13. The monitor of claim 9 , wherein the conductive material comprises carbon.

14. The monitor of claim 9 , wherein the electrode strip comprises an adhesive layer disposed on each of two sides so that one side can be releasably adhered to the first side of the flexible waterproof enclosure and the other side can be releasably adhered to the skin of the subject.

15. The monitor of claim 9 , wherein the circuitry comprises a digital processor and a battery.

16. The monitor of claim 9 , wherein at least one third polymer chain in a third portion of the flexible waterproof enclosure that is infused with the conductive material at the second location is cross-linked with at least one fourth polymer chain in a fourth portion of the flexible waterproof enclosure that is not infused with the conductive material.
