ASTUS provides doctors, nurses and their patients, with a simple yet effective solution for remote monitoring of patient health.
The ASTUS solution allows performing vital physiological measurements on the patient and sending them, through secure transmission, to a secure file server accessible by the doctor (via WIFI, cellular networks or satellites). Measurements can be performed by the patient, a relative, or a nurse. The doctor receives the medical data concurrently, is alerted when certain conditions are met, and accordingly can take actions such as sending prescriptions, arranging further assessment, moving the patient, etc. The basic kit, weighing about 1 kg (0.45 lbs), contains equipment for measuring temperature, blood pressure, heart rate, blood oxygen level and blood sugar levels. An electrocardiograph (ECG) and an echograph are also available. At the system’s core is a touch screen mobile phone that allows administrative interactions such as selecting a patient, checking the prescription and the list of actions to be performed, recording measurements wirelessly or manually, and initiating transmissions to the doctor. The nurse may also take photographs and capture voice or text messages which will also be sent to the doctor.
The Personal Medical Record of patients is updated with any measures taken, and these may be accessed at any time by the doctor from anywhere in the world through a Web application, accessed by any PC, MAC, tablet or Smartphone connected to the Internet.
The concerned population is quite large: travellers, people in isolated rural zones, those in residential care, the chronically ill, hospitalized patients in need of regular monitoring, etc.
Use case scenario:
The target for this use case is to demonstrate the feasibility and to evaluate wearable health or wellness sensors developed in the context of the project. This will be achieved by integrating them to an existing operational telemedicine platform that will allow correlating the data supplied with data retrieved by conventional sensors for diagnosis.
Technological requirements, state of the art, main deadlocks:
The main challenge is the development of adequate wearable sensors: very low power (possibly utilizing harvesters), small factor, with high endurance, easy to integrate to clothing or directly to body, able to communicate with the patient’s smart phone (directly or indirectly through a data concentrator device) in order to transfer the measurements. Computation power is not that important since the bulk of computation required can be performed by the smart phone.
