  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. Our Project • 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

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

  5. Project Selection Process Voting: Ranked Projects 1-6 Top three projects discussed Weighed pros and cons Overall compatibility as a class/group project

  6. 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.

  7. Wireless Patient Monitoring System

  8. Project Schedule

  9. 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

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

  11. 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

  12. 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.

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

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

  15. Patient: Armband • Easy to maneuver and lightweight • iPod Armband • 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

  16. 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

  17. 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

  18. 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

  19. 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

  20. Nurse’s Station: LabView Demo

  21. Outline

  22. 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

  23. Parts List

  24. 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

  25. 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
