Wireless Patient Monitoring System
Digital Health SectionProfessor: Patricia Mellodge
The use of electronics; through the use in or on the body to assist medical professionals when treating various illnesses and ailments
They would focus in three main areas Prevention Diagnosis Curing
What is Digital Health?
Reduces the use of wires in the room through the use of wireless transmission
The project is mainly designed to collect information on the patient Location Temperature
Our Project
First Ideas:Pollution Filter MaskOxygen Tank Flow RegulatorOrthopedic ShoesArthritic Glove
Project Selection Process
Voting: Ranked Projects 1-6 Top three projects discussed Weighed pros and cons Overall compatibility as a class/group project
Project Selection Process
To construct a wireless system containing a hospital bed, computer monitor, and a patient sensor rig; which
would alert an outside party of a patient’s position and
medical status.
Objective
Wireless Patient Monitoring System

Bed Monitoring: Objective
Bed sensors determine if patient is in bed
Switches in a grid pattern are used to determine the patients location
Can be used in various hospice settings
6’ x 2’ egg crate foam mattress pad
2 sheets of 6’ x 2’ plywood12 contact switchesMiscellaneous assembly hardware
Bed: Materials
Contact SwitchesThe switches are constantly
open unless depressed by a patient on the bed.
This will send a high(1) signal to the microcontroller
Bed: Materials
Bed Monitoring: Design One sheet of plywood serves as a base, while the
switches are mounted on top of it. The second sheet of plywood has holes drilled in it.
When the switches are depressed, they are flush with the top sheet of plywood.
Egg crate foam pad rests on top of the plywood to create a comfortable sleeping environment.
Prevention of accidents through awareness of
patient status, accurate monitoring of position,
temperature, and orientation
Patient: Objective
Use a microcontroller to wirelessly transmit information from:Temperature sensorAccelerometer and tilt sensorsIndicate body orientation and location

Accelerometer
Through LabVIEW, we can make a presentable way to show the nurse the information on each patient that needs to be monitored.
We take data from the sensors taken from the other groups and present them in an organized manner
To do this, we use a wireless receiver in order to gather the data from their sensors
Nurse’s Station: Objective
LabVIEW is used to display the information obtained from the patient and bed sensors
Transceiver will request and receive packets of data from all the sensors on the network
Nurse’s Station: Parts
LabVIEW will: Receive data from transceiver Parse the sensor data from the data
packet Utilize algorithms to filter
accelerometer data Display the patient's information to
the user
Nurse’s Station: The Plan
Nurse’s Station: LabView Demo

A wireless system has several advantages such as: Patient safety Low maintenance Ease of mobility for the
caretaker/patient Capacity for transmitting information
No need for a bulky monitoring station
Advantages
Satisfies a demand for monitoring: Unattended falls, heart attacks, fevers,
and several other medical mishaps Societal demand for this system due to
staffing constraints Applicable in a home setting Easy interface with future link to app on
portable phone
Advantages
