September 28th Meeting Minutes I. Member Reports. A. Colby hasn’t heard back from Dr. at Gritman.
1. Don suggests making a friend at the hospital, possibly the receptionist.
-Let them know what we’re doing, maybe this person can further help us get what we want.
-Keep in mind, the sleep center operates primarily at night.
-Little gestures like thank you notes make all the difference.
B. Colby has also contacted someone at the mines building about a CO2 sensor.Still waiting to hear back.
C. Jeff has narrowed the code search to the IEC 60601-1
1. It is apparently the cornerstone document addressing many of the risks associated with electrical medical equipment.
D. Jen has located a SIDS organization in the state of Washington.
E. Don offers a reminder to be careful when acting against the will of the client.
(Client phone conference segment of meeting was canceled due to lack of information to report.) II. New Business A. We will be switching to an “Edit me” format for the website. 1. Colby and Lloyd will meet with Don at 8:30 Friday morning (29th) to set up and pay for the new website.
B. Problem definition brainstorm. (The features of our ideal monitor)
1. Cost
-Affordable, keep in mind the difference between manufacturing price and retail price. Also component cost.
-Affordable replacement parts. 2. Safety
-Must comply with the IEC 60601-1 standards
-Low voltage
-No sharp edges
-No wires for the infant to become entangled in
-Must be crib safe
-Must not be a swallow hazard
-Must be composed of bio compatible materials 3. Functionality
- Simple interface to operate
- No instruction book needed.
- Easy to clean
- Easy to reassemble
- Detects when breathing stops as well as troubled breathing.
- Detects heart rate
- Provides feedback about which sensor set off the alarm.
- User must have the ability to turn off the alarm.
- Has ability to record and present alarm history. 4. Reliability
- No false alarms
- Low battery indicator
- No false negatives
- Redundancy measurement
C. Prototype
1. Our short term goal is to have built a simple prototype by next Thursday (Oct 5th). We will meet on Wednesday (Oct 4th) in the senior design suite at 5:30 pm to build prototype.
- Focuses on one function
- Substitute expensive components with innovation
- Sketch ideas in log books, identify and acquire needed parts
2. Team consensus on prototyping.
- We will focus on a new prototype each week. Each being based on one specific sensor or sensing method.
-Prototype #1 will focus on sensing pressure changes in an inflatable air mattress.
III. Closing
A. Action items.
1. Bart will look for cheap pressure gauges in town
2. Lloyd will probe the physics department for a pressure gauge. Possibly a strain gauge.\
3. Colby and Lloyd will meet with Don Friday morning (29th) to set up the new website.
4. Colby will offer up his therma-rest air mattress to the gods of invention.
5. Jeff will locate the IEC 60601-1 on campus. Hopefully at the library.
6. Every one document your ideas. Keep brainstorming practical and innovative ways to use these sensors on this air mattress. Share ideas over email.
B. For meeting #4
1. Refine our problem definition
2. Have prototype #1 finished and test results ready to present to Dale.
3. If we have time, do an assessment of the meeting. (What went well? Not so well?)
Closed at 5:00pm |
