Wireless Patient Monitoring System

1. Wireless Patient Monitoring System Digital Health Section Professor: Patricia Mellodge May 4, 2012

2. What is Digital Health? • The use of electronics; in or on the body to assist medical professionals when treating various illnesses and ailments • Projects can focus in three main areas • Prevention • Diagnosis • Curing

3. Wireless Monitoring System • Prevent further injuries • Wireless reduces risks • Collect information from patient • Location • Temperature

4. Project Selection Process • First Ideas: • Wireless Patient Monitoring System • Pollution Filter Mask • Oxygen Tank Flow Regulator • Orthopedic Shoes • Arthritic Glove

5. Project Selection Process Voting: Ranked Projects 1-5 Top three projects discussed Weighed pros and cons Overall compatibility as a class/group project

6. Results • Top three choices were: Wireless Patient Monitoring System, Pollution Filter Mask, and The Oxygen Tank Flow Regulator • Choose Wireless system because: • Filled all digital health requirements • Whole class could contribute • Relevant use in real world • Very broad consumer base • Integrates and improves already existing concepts

7. Objective • To construct a wireless system containing: • a hospital bed • computer monitor • a patient sensor rig • which would alert an outside party of a patient’s position and medical status.

11. 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 settings

12. Bed: Materials 6’ x 2’ egg crate foam mattress pad 2 sheets of 6’ x 2’ plywood 12 contact switches Microcontroller Miscellaneous assembly hardware Power source (lithium battery)

13. Bed: Materials Switch • 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 Trigger

14. 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.

15. First Design New Design

16. Patient: Objective Prevention of accidents through awareness of patient status, accurate monitoring of position, temperature, and orientation

17. Plan • Use a microcontroller to wirelessly transmit information from: • Temperature sensor • Accelerometer and tilt sensors • Indicate body orientation and location

18. Temperature sensor Accelerometer and tilt sensors- Specifications: for each and picture

19. 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

20. Patient: Armband • Easy to maneuver and lightweight • iPod Armband houses the enclosure of parts • Altered iPod Armband will house enclosure 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

21. Nurse’s Station: Objective To 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

22. Nurse’s Station: The Plan • Through LabVIEW, we 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

23. 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 USB dongle is used to integrate the transceiver with the computer

24. Nurse’s Station: LabView Demo

25. Outline

26. Proof of concept(Bed to Nurse’s Station)

27. LabVIEW Code

28. The Final Nurse’s Station

29. Budget < $350 • Goal was to shop efficiently • Buy only essential parts • Buy the cheapest compatible parts • Research each part individually • Write a proposal • Have it approved

30. Patient Group

35. Results Split into Comparison Table: Temperature was: Position was :

36. 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

37. 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

38. Possible Improvements • Addition of different sensors • Heart rate • EKG • Farther transmission range • Ability to monitor more patients
