Contents Introduction System Design  Home Healthcare End (HHE)  E-healthcare Control Center (ECC)  E-healthcare Service Provider (ESP) Seamless Healthcare Information Delivery (SHID) System Implementation

Introduction As society becomes aging  senior patients suffer from visiting hospital routinely  social cost >> healthcare cost Low cost healthcare system  becomes more evidential and important  Using state-of-the-art technologies

System Design -Overall Sensor-based Pervasive Healthcare (SPH)  To develop an automatic and flexible physiology sensing system  To achieve a complete telemedicine, emergency medicine, and high quality healthcare environment

System Design -Overall Consists of  Home Healthcare End (HHE)  E-healthcare Control Center (ECC)  E-healthcare Service Provider (ESP)

System Design -Home Healthcare End (HHE) HHE system architecture  Sensor Equipments  Healthcare Engine (HE)

System Design -Home Healthcare End (HHE) Sensor Equipment includes  Vital sign and Video sensors  Command Agent (CA) To process the healthcare query from HE (Healthcare Engine)  Transmission Unit Transmit the sensed healthcare data to HE

System Design -Home Healthcare End (HHE) Healthcare Engine (HE)  Transmits the query  Receives data from sensors  Provides universal interface for Communicating with E-healthcare Control Center (ECC) and e-healthcare service providers (ESPs)  Allows web-based simple configuration of system parameters

System Design -E-healthcare Control Center (ECC) Coordinates between HHE and ESPs ECC system architecture

System Design -E-healthcare Control Center (ECC) Location Service (LS)  Records the location of each patients Registrar Server (RS)  Authorization, authentication, and accounting for users  Adopts Session Initiation Protocol (SIP) Session Agent (SA)  Establishes a communication session for transfer of data

System Design -E-healthcare Control Center (ECC) Session Agent (SA)  Establishes a communication session for transfer of data Mobility Agent (MA)  Assists healthcare professionals in using the same session service across heterogeneous networks and appliances  Seamless healthcare Information Delivery (SHID) is proposed Network Adapter (NA)  Data transmission

System Design -E-healthcare Service Provider (ESP) Provides necessary healthcare services  Emergency healthcare centers (EMCs)  Hospitals and ambulances

System Design -E-healthcare Service Provider (ESP) Instant Message Module (IM 2 )  Receives and sends instant messages from and to HHE Push Agent (PA)  Extracts information from XML and sends to HHE and ECC XML Profile and Generator  Records information regarding ESPs and aggregates it to XML

Seamless Healthcare Information Delivery (SHID) “Healthcare professionals should ideally have access to healthcare information at any time or from any place” Seamless Healthcare Information Delivery (SHID) proposed

Seamless Healthcare Information Delivery (SHID) Based on the Session Initiation Protocol (SIP)  Establishes, modifies, and terminates multimedia sessions And PUSH technology  Healthcare Professionals can access up- to-date healthcare information

Seamless Healthcare Information Delivery (SHID) SHID system architecture

System Implementation Designed for immediate application Adopted environments  S/W: J2SE, J2ME, Eclipse, MapObject 2.0 and MySQL  H/W: Vital sign sensor kits, Tablet PC, PDA, IP cameras, wireless microphone/ earphones and GPRS module

System Implementation -Home Healthcare End (HHE) Sensors  LapPro ECG sensor connected to a MOTE processor  MOTE transmission unit transmits the sensed data to Healthcare Engine (HE) IP Video Camera  Distributed on the WDS and MANET

System Implementation -Home Healthcare End (HHE) Node M  Sensors  Detects and collects the physiological data Node G  Works as the network gateway  Aggregate Node M data to Node V Node V  IP video camera  Also work as gateway to Node N

System Implementation -E-healthcare Control Center (ECC) Provides  UI showing the physiological data and Patient’s information  Online E-healthcare Service Providers (ESPs)

System Implementation -E-healthcare Service Provider (ESP) Based on Context-Aware emergeNcy rEmedy system (CANE)  Provides communication platform for lifesaving  Uses GIS/GPS to provide location-based services
