INTRODUCTION

Repeated or continuous observations or

measurements of the Patient , his or her

physiological function from remote location.

Objective of Remote Patient Monitoring

Continuous monitoring of health status of patients.

Extend independent living for the elderly persons.

Reduce demand of caregivers.

•Temperature•Heart Rate•Blood oxygen saturation level etc.

Health Parameters to be measured:

BUILDING BLOCKS

• 5V Regulated Power Supply

Temperature Sensor

Heart Rate Sensor

Blood Oxygen Saturation Level Sensor etc.

• PIC Microcontroller

• Sensors

• Wi-Fi Module

• PC Interface

BUILDING BLOCKS CONT.

• 5V Regulated Power Supply

1. 230 -9V step down transformer

2. Bridge rectifier3. Capacitor DC filter

4. 5V regulator IC

BUILDING BLOCKS CONT.

• SENSORS

1.Temperature Sensor

Calibrated directly in Celsius

Accuracy:10mV/deg. COperating voltage : 4-20VTemp. range: -55deg. C to

150 deg. C

BUILDING BLOCK CONT.

2.Blood Oxygen Saturation Level & Heartbeat Sensor

The finger probe has a photo detector and two LED’s to transmit light

across the fingertip: one Red (660 nm) and one IR

(895 nm).

START

Get Sensor info

Check monitoring

system ready or

not?

YES

Get remote monitoring system connection status

OK or NOT?

NO

NOSHOW

SYSTEM ERROR

Send patient information to remote server

YES

log it to file

NO

do process in infinite loop

STOP

FLOWCHART

Check if the patient health parameters is

within standard range

YES

Send immediate notification locally and take action accordingly

ADVANTAGES

•Bridging the gap between the doctor and the patients.

•Best to be used in rural areas.

•Easy to operate

Future scope

Clinical care can be provided with such a

system that computerized decision-support is

feasible and can aid in providing more cost-

effective and improved patient care.
