Architecture

Introduction#

Vitabits is a platform for monitoring patients at a distance. It helps medical staff to communicate with patients and acquire their vital signs without any need for patients to physically visit the doctor.

The platform is specifically appropriate for remote monitoring of patients with chronic diseases, such as diabetes, asthma, congestive heart failure, arterial hypertension, COPD, etc.

Using the platform, the doctor can prescribe a home care therapy for a patient, including self-measurement of various vital signs and other activities to acquire data for efficient treatment. The platform allows the doctor to communicate with the patient over a video call and instant messaging and to call the patient for a physical visit if required.

Based on regular observation of patients’ health conditions, doctors can provide more accurate diagnosis and adjust treatments as needed. This contributes to higher efficiency of health care and consequently lowers the associated costs.

Integration#

Integration with external backend systems is possible via Vitabits Subscriber API.

Components#

Vitabits ecosystem consists of the following components:

  • Vitabits Hub
  • Vitabits Platform
  • Admin portal
  • Supported measurement devices

Measurement devices#

Vitabits enables remote acquisition of all important vital signs and other data that can contribute to understanding of patient conditions and can help doctors to give efficient treatment.

Vital signs can be measured by any measurement device that communicates over Bluetooth protocol (BT or BTLE) and is Continua certified or uses standard GATT services. At the moment, vitabits hub integrates over 50 measurement devices selected by independent medical specialists. The device manufacturers include: Rossmax, Nonin, A&D Medical, ChoiceMMed, Roche, Philips, ForaCare, Contour, Fitbit ... All devices have acquired certificate of "European Conformity".

Measurement devices can be easily added or removed using graphical interface (over hub or management portal) or programmatically over API.

Vitabits offers an API with push&pull services for the communication with any available backend system. By design, it supports and promotes the communication with FHIR or OpenEHR compliant systems.

Vitabits Hub#

Hub or gateway is a software that supports an easy and efficient self-measurement of patient’s vital signs and their safe transfer to the cloud. The software is generic, i.e. it runs on a smart phone, tablet, TV-box or on a dedicated standalone device. Thanks to the hub, the whole measurement process is transparent – patients don't need to care how to connect devices or how to send measured data to the backend system, as all these is done automatically by the hub. At the same time, the hub represents the main communication channel between patients and their treating physicians.

Basic functionality
  • Easy integration with various measurement devices and sensors,
  • Secure transfer of data to the backend system,
  • Support for daily activities, reminders, and warnings,
  • Representation of measurement data in a table or on a graph, with a reference intervals and trend lines,
  • Support for video communication / instant massaging between patients and treating physicians,
  • Support for remote management of connected devices,
  • Support for remote software update.

Vitabits Management Platform & Admin portal#

Management platform is a cloud enabled server that implements all required functions for remote management of vitabits hubs and connected devices. The management services are available through GUI of Admin Portal or over dedicated API. At the same time, the platform serves as a safe and secure data storage.

Basic functionality
  • Remote management and control of active hubs and connected devices,
  • Administrative support for the entire life cycle of remote patient monitoring, including technical support for service activation and deactivation, troubleshooting, system update, QoS assurance, notifications, remote device management etc.,
  • Application program interface (API) implementing Push&Pull services for remote platform management and data retrieval,
  • Safe and secure repository for data, captured within the remote patient monitoring. The data in the repository is encrypted and only available to patients (owners) and authorized medical personnel.
