## Abstract

The present subject matter relates to absorbent articles and signaling devices for use therewith. The signaling device can be configured to detect the presence of an insult in the absorbent article and/or in an undergarment. The signaling device can be further configured to determine whether the insult is a urine insult or a feces insult. The signaling device can provide a notification to a user that an insult has occurred and can inform the user whether the insult is a urine insult or a feces insult.

## Claims

### Claim 1

A bed pad with a body fluid sensor comprising:
a first absorbent layer;
a second absorbent layer;
wherein the first absorbent layer further comprises a first conductive thread having a first length and a first metal attachment means on a first end of said first conductive thread;
wherein the second absorbent layer further comprises a second conductive thread having a second length and a second metal attachment means on a first end of said second conductive thread;
wherein the first conductive thread and the second conductive thread are disposed on the first and second layers respectively such that said first and second conductive threads do not contact each other thereby forming an open circuit;
wherein the first and second metal attachment means provide a conductive platform configured to allow power to be supplied to the open circuit through the attachment means;
wherein the first and second conductive threads form an open circuit under dry conditions, and wherein said open circuit is completed in the presence of a moisture insult causing an alarm signal indicating the presence of said insult.

### Claim 2 (depends on 1)

The bed pad of claim 1, wherein said pad has an adhesive backing.

### Claim 3 (depends on 1)

The bed sensor pad of claim 1, wherein the alarm signal is transmitted to a caregiver or nursing station.

### Claim 4 (depends on 1)

The bed pad of claim 1, further comprising a moisture barrier layer.

### Claim 5 (depends on 1)

The bed pad of claim 1, wherein the layers of said pad are configured and sewn such that said first and second conductive threads to not contact each other when said pad is wrinkled or folded.

### Claim 6 (depends on 1)

The bed pad of claim 1, wherein said alarm signal is a visual or audible signal.

### Claim 7 (depends on 4)

The bed pad of claim 4, wherein said alarm signal is transmitted to a remote device.

### Claim 8 (depends on 7)

The bed pad of claim 7 wherein the remote device is a smartphone or an IP based network.

### Claim 9 (depends on 1)

The bed pad of claim 1 wherein the circuit is powered by battery or AC power source.
