Introduction (1/2)

• Why
• The world population is rapidly aging and at a
  growing rate.
• The related health costs.
• To enhance elder daily life independence and
  reduce the social and economic overhead of elder
  hospitalization.
• How Ubiquitous computing and communication
• technologies
• Wireless network (Bluetooth?GSM /GPRS)
• A variety of Sensors (wearable biosensors)
• Portable Devices (mobile Phone?PDA)

Service Analysis and Healthcare Scenarios

• Patients do not Upload Physiological Parameters
  on schedule
• Result of Measurement is Abnormal and our system
  Automatically infors Care Providers

System Architecture

• tracing information packages (TIPs)
• TIP(TIPID, EventID, EdlerID, State, DateTime)
• TIPID is the increasing serial number of each
  TIP.
• EventID is the unique event ID,
• ElderID is the elders social ID number referred
  to as ELDER entity.

System Software Designs(1/3)

• Blood Pressure and Pulse Monitor software Module
• ECG Monitor Module
• Healthcare Center Server Program Design

9
System Software Designs(2/3)

• Unified Modeling Language (UML)
• The design phases are as follows
• requirement analysis,
• object model design,
• code implementation for software model,
• simulator execution,
• And upload to real mobile phone Nokia 7610 for
  final test.

10
System Software Designs(3/3)

• The Healthcare center host
• Borland C Builder 6.0,
• ActiveX data objects (ADO) components are used
  to access ACCESS database,
• advance technology (AT) command instruction set
  is used to control GSM module to transmit and
  receive short message.

t , T, dt1, dt2 and dt3 t is the elapsed
time after alter is transmitted. T is the
default deadline. dt1 is the urgent deadline
dt2 is the critical deadline dt3 is the very
critical deadline

System Implementation(1/5)

• three main portions
• Front-end wireless mobile care devices including
• the Bluetooth hemadynamometer
• and wireless ECG extraction device
• A commercial mobile phone of model Nokia 7610 was
  used.
• A healthcare center server
• applications

System Performance Evaluation
Implementation of Monitor Software Module in
Healthcare Center Server(2/2)

• The results show that the best and worst time
  latency of Tsmslatency are 4.36 and 17.36 s.
• The patient will receive healthcare no later than
  17 min and 30.8 s after the alert is initiated.
• The back-end healthcare center will receive
  related response messages from healthcare
  providers in the third level within 20 min and
  30.8 s.

25
System Performance Evaluation
Questionnaire Survey and Evaluation of System
Costs

• the capital cost for the system setup is about
  NT 5000 and the operating cost is only NT 200.
• the cost for the Bluetooth wireless
  hemadynamometer is NT 3000
• The Nokia 7610 mobile phone costs only NT 2000
• the monthly fee of NT 200 for unlimited sending
  of SMS within the same telecom network.

26
Discussion and Conclusion(1/2)

• This paper has proposed a role-based mobile
  healthcare system for chronic patients with an
  integration of multiple physiological parameter
  extraction devices.
• The capital cost for the system setup is about
  NT 5000 and the operating cost is only NT 200.

27
Discussion and Conclusion(2/2)

• Is it slow for a patient to get services in 17
  min ?
• Is it cheap enough for a patient to pay NT 5000
  in order to get the service ?
• The fatal problem is that the healthcare provider
  does not know accuracy position of the patient.
