An assembly of electronic devices designed to provide an alarm signal to summon help when activated in response to a patient’s need for urgent assistance or care (e.g., epileptic seizures, falls, low insulin levels). It typically consists of user- or sensor-activated wireless signal transmitters (e.g., patient-worn pendant, wall push-button, fall sensor) and alert communication devices (e.g., network interface, phone, pager). Also known as a personal emergency response system (PERS), it notifies caregivers, neighbours, or emergency medical services (EMS), and is intended for use in the home.
