The US had seen the launch of DFree, a wearable connected health monitor that uses an ultrasonic sensor to alert users to a full bladder.
Changes in bladder size are monitored via a sensor secured to the abdomen with medical tape. A receiver then clips to the wearer’s belt. The device can track the progression of bladder movements and predicts urination timing using a patented algorithm. It sends data to an iOS app which can be set to alert when the wearer's bladder is full to a chosen threshold. The notification can be sent to a smartphone or tablet used by either the patient or caregiver.
While DFree is not intended to be used in the diagnosis, prevention, or treatment of diseases it can predict and inform as to when it is necessary to go to the bathroom and in doing so the goal is to help the many patients that suffer from urinary incontinence.
