Pressure sensitive pads for in bed use to sense when a patient is attempting to leave the bed. The 'bed' pads are designed to go beneath the sheet or mattress protector on top of the mattress. The 'mattress' pads are designed to go between the bed base and the mattress. Both will activate an alarm when the persons weight is removed from the bed. For rest home or hospital use where a nurse call system is present the standard kit will suffice but if using in a domestic caring situation a wireless kit will be required.
