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

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

5. 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

6. 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.

Groups • Nurse’s Station • Alex LaMarche • Shanique Jiles • Tim Zimmerman • Luis Luna • Bed Group • Feng Chen • Gino Cardone • Benjamin Basso • Jeremy Harvey • Rajin Roophnath • Stephen Sett • Matthew Smith • Patient Group • Nathan Coutermarsh • Dillon Quadrato • Dana Subki • Loay Alabdulmohsin • Jason Jolles • Kevin Veilleux • Alyssa Broatch • Melvin Peralta • Stacey Dufrane

9. Wireless Patient Monitoring System

10. 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

11. 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)

12. Bed: Switches 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

13. Bed: Designs First Design New Design

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

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

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

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

18. 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

19. 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

20. 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

21. 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

22. Nurse’s Station: LabView Demo

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

34. 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

35. 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

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