Introduction

As society becomes agingsenior patients suffer from visiting

hospital routinelysocial cost >> healthcare cost

Low cost healthcare system becomes more evidential and importantUsing state-of-the-art technologies

System Design -Overall

Sensor-based Pervasive Healthcare (SPH)To develop an automatic and flexible

physiology sensing systemTo 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 architectureSensor Equipments Healthcare Engine (HE)

System Design-Home Healthcare End (HHE)

Sensor Equipment includesVital sign and Video sensorsCommand 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 queryReceives data from sensorsProvides 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

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 servicesEmergency healthcare cente

rs (EMCs)Hospitals and ambulances

System Design-E-healthcare Service Provider (ESP)

Instant Message Module (IM2) Receives and sends instant messages from and to HH

E 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
