Enuresis treatment device
First Claim
1. A device for treating an enuretic person by conditioning said person to avoid nocturnal bed wetting, said device comprising:
- a urine detecting pad arranged to be placed underneath said person while asleep for absorbing urine discharged by said person, said pad changing its state in corresponding relationship with the quantity of urine absorbed by said pad;
detection signal means coupled to said detecting pad for producing detection signals corresponding to the state of said urine detecting pad;
an alarm for providing an aversive stimulus to said person;
alarm energization means coupled to said alarm and said detection signal means for energizing said alarm when said detection signals are above a first level corresponding to a first quantity of said absorbed urine; and
alarm cutoff means coupled to said alarm and said detection signal means for disabling said alarm after a particular elapsed time when said detection signals are below a second level corresponding to a second quantity of said absorbed urine, and for allowing said alarm to remain energized when said detection signals are above said second level;
whereby said alarm is energized only over a sufficient time to provide an aversive stimulus to said person while asleep when less than said second quantity of urine is discharged by said person, and said alarm remains energized when more than said second quantity of urine is discharged by said person to thereby awaken said person.

Abstract
A device which provides an aversive stimulus to a child who bed wets while asleep includes a urine detection pad of absorbent material having wire screen electrodes on both sides thereof, and an electrical circuit including an aversive alarm which is triggered when the detecting pad is moistened by a small amount of urine. A preferred embodiment of the device shuts off the alarm within a short time period if the total amount of urine deposited on the detecting pad is below a given quantity. If more than the allowable quantity of urine is deposited, the alarm continues to expose the child to the aversive stimulus. The device may also feature an adjustable threshold in its circuit to permit variation of the total quantity of urine required to continually energize the alarm, as well as selectable sensitivity of the circuit to the initial deposition of urine so that dampness caused by perspiration or humidity will not trigger the alarm.
