Bedwetting alarm is an electronic device used as a treatment option for nocturnal enuresis. Bedwetting alarm activates when the wearer urinates. Bedwetting alarms come in several different styles: wearable bedwetting alarms, wireless bedwetting alarms, and pad-type alarms. While there is some variation in the styles of the alarms, they all function similarly. Bedwetting alarm is an option to treat children who are wetting the bed at night. Using an alarm reduces bedwetting in about two thirds of children during treatment, and about half the children remain dry after stopping using the alarm.

Working of Bedwetting Alarms

Bedwetting alarm has a moisture sensors and an alarm circuit. The sensors are usually so sensitive that the alarm goes off as soon as the child starts to wet (pass urine). When the child first begins to urinate, the sensor will detect the moisture and trigger the alarm. This wakes the child who then stops passing urine. The child should then get up and finish off in the toilet. This conditions the child to wake up and go to the toilet if he or she starts to wet the bed, or is about to start. In time, the child is conditioned to wake when their bladder is full before they begin wetting, or learns to sleep through the night without wetting the bed.

Types of Bedwetting Alarms

  • Wearable Bedwetting Alarms – A wearable alarm is a design in which the child wears the moisture sensor in or on their underwear or pajamas. This type of sensor will detect moisture almost immediately. The sensor is attached to the alarm unit with a cord that can be worn under the shirt.
  • Wireless Bedwetting Alarms – A wireless bedwetting alarm is one in which the sensor and the alarm unit communicate by wireless connectivity. The transmitter, which senses the moisture, is directly attached to the child’s underwear. The signal is transmitted wirelessly to a unit that is across the room from the child or an alarm unit in the child’s room. Once the alarm unit is activated, it is necessary to get out of bed to turn it off. New wireless alarms add the convenience of also sounding an alarm in the caregiver’s room, allowing both patient and caregiver to sleep in the comfort of their own beds and rooms.
  • Pad-type Bedwetting Alarms – Bell-and pad alarms do not attach to the child in any way. The moisture sensor is in the form of a pad or mat that the child sleeps on top of. The pad detects moisture after urine has leaked onto it. The alarm unit is connected with a cord and usually sits on the bedside stand. This alarm requires a larger amount of urine before the sensor can detect moisture. The person must be on the pad for it to sense moisture.
