Wireless Patient Monitoring System

1. Wireless Patient Monitoring System 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.

6. Wireless Patient Monitoring System

7. Project Schedule

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 Image obtained form: http://mp3.about.com/od/iPod-MP3-Player-Accessories/tp/Top-5-Ipod-Armbands-Listen-To-Digital-Music-On-Your-Ipod-While-You-Exercise.htm Altered iPod Armband will house enclosure

15. Patient Accelerometer • Patient Rig • Supports mobility • Unobtrusive location • Lightweight design Tilt Sensors Armband Original image obtained from: http://www.mrprotocols.com/oldsite/MRI/information.htm

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

20. Outline

21. Budget < $300 • Goal was to shop efficiently • Buy only essential parts • Buy the cheapest compatible parts • Research each part individually • Write a proposal • Have it approved

22. Parts List

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
