Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Preliminary Design Draft near completion
Currently working on first prototype construction
Both helping hands and peel & stick rubber pads have been purchased : http://www.eagleamerica.com/product/420-3012/safety_supplies
Need to decide on & buy tubes and tubing adapters
Both will be purchased through Chemistry & Biochemistry stock store
Accomplishments from Previous Week
Tubing size is determined with input from sponsor
Drainage design has been extablished and incorporated into the prototype
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Jasmine - Tilting device and purchasing parts
The tilting device is considered toward as an attachment as the chamber will be used for more than just imaging platform
Tubes and tubing adapters will be purchased through stock room for Chemistry and Biochemistry
Work with Will on incorporating tilting device into CAD drawing for final assembly (if needed).
Jordan - Purchasing tubing adapters and the tubes for testing
Size of tubes and tubing adapters have been determined.
During last week's meeting, the sponsor showed us where to purchase both items on campus (rather than travel to Hillcrest for parts from UCSD Hospital)
Tygon will be used for prototype testing (available in quantity and inexpensive in stockroom).
Paul - Construction of the first prototype
Due to the 3D printer in deisgn studio currently out of service, the reservoir will be constructed possibly through CalIT2
The helping hands mounting rail will be constructed through LaserCAM
Figuring out how to incorporate drainage during construction.
Will - Finishing up the CAD design
The CAD drawing will incorporated tubing holes
The size of holes is now determined through confimation with sponsor.
The incorpration of drainage system into finalized CAD drawing
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
In person on April 15, 2013
Sponsor is due for traveling during the week. As the result, only one member is available at the time of of which sponsor is available for meetingÂ
The tube size actually depends on the needle that is used to attach the tubes to the lungs
The sponsor provided the 18G needle. Through research it is determined that the size of tube corresponding to 18G is around 1.25mm in diameter.

Pump: What kind of pumps will be used to channel solutions and air into lungs?
The pumps most likely used for such task will be peristalic pumps or similar kind
Can the tubes handle such pressure from pumps?
Yes. Based on the experience most silicon and tygon kind of tubes are strong and flexible. In addition, the pump power won't be too high and the amount of solutions and sir which need pumping are not much either.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
None
Risks and Areas of Concern
How to keep all of the connections to the lung stable through use of helping hands
How to connect the acrylic and the 3D printed parts together while making them water tight and rigid/ secure
Resources or Information Required but not Available
None
Schedule
Update the design with confirmed tubing size hole
Have the reservoir part of the chmaber construct through 3D printer
Purchase the tubes and tubing adapter for testing.
Budget (list amount spent and amount remaining)
