Digital Health Section
Professor: Patricia Mellodge

2. What is Digital Health?
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

3. Project Selection Process
First Ideas:
Pollution Filter Mask
Oxygen Tank Flow Regulator
Orthopedic Shoes
Arthritic Glove
Voting: Ranked Projects 1-6,
top three projects were discussed
Weighed pros and cons
Overall compatibility as a class/group project

5. Objective
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.

8. 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

9. Bed: Materials 6’ x 2’ egg crate foam mattress pad
2 sheets of 6’ x 2’ plywood
12 contact switches
Miscellaneous assembly hardware

10. Bed: Materials Contact Switches
The switches are constantly open unless depressed by a patient on the bed.
This will send a high(1) signal to the microcontroller

11. 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.

12. Patient: Objective
Prevention and awareness of danger to the patient through accurate monitoring of position, temperature and orientation

13. How Use a microcontroller to wirelessly transmit information from:
Temperature sensor
Accelerometer and tilt sensors
Indicate body orientation and location
Easy to maneuver and lightweight
iPod Armband

14. Patient: Armband Easy to maneuver and lightweight iPod Armband
Altered iPod Armband will house enclosure

16. Nurse’s Station: Objective
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

17. Nurse’s Station: Parts
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

18. Nurse’s Station: The Plan
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

19. Nurse’s Station: LabView Demo

23. Advantages 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

24. 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
