Bed wetting alarm

Modern technology has produced a wide variety of electronic devices for alerting nurses to various difficulties encountered by patients. Among those devices are means responsive to bed wetting occurrences. The basic bedwetting prevention system utilized in homes, hospitals, and extended care facilities provides a number of essential elements intended to detect the condition and to transmit and receive a signal to alert either the user and/or the caregiver. A number of bed wetting alarms exist. They typically sense the presence of urine by its electrical conductivity, creating an electrical signal which is then used to set off an alarm. The alarm, typically a buzzer or other audible alarm, must wake the user as quickly as possible after urine has been detected in order to minimize the necessary user response, and to facilitate the user's, learning to avoid bedwetting. Many bedwetting alarmss are designed simply to alert a caregiver in order to minimize the time that the user must remain in wet bedding and clothing. Other systems disclose devices designed to wake the user upon activation of the wetness sensor. The basic existing system incorporates a fluid sensor, a sensor signal transmitter, and a signal receiver alarm unit. There is typically a switch which operates to deactivate the system. There is also typically a remote receiver designed to alert a parent or a caregiver. In addition, most bedwetting systems are directed to detection of moisture and dry skin maintenance rather than a behavior modification program to eliminate bedwetting altogether.
