Endotracheal tube adaptor for administration of aerosolized medicationsClient:! Dr. Mark E. SchroederTeam Members: ! Ryan Childs (BSAC) ! Ozair Chaudhry (Communicator)! Timothy Barry (BWIG)! Evan Joyce (Leader)Date:! October 9 to October 16, 2009Problem StatementThe goal of this project is to make design changes to an endotracheal tube adaptor that was fabricated last semester for product optimization. The adaptor works as an interface to introduce aerosolized medication (e.g. Albuterol) from a pressurized canister into an anesthesia circuit to an anesthetized, intubated patient. This project was initiated due to a recent change in the Albuterol canister used by the UW-Hospital. The new canisters have been fitted with a non-removable, plastic, actuation counter resulting in a mechanical incompatibility with the old adaptor used at the hospital. The adaptor should not impede the anesthesia circuit which flows at a rate of 4-5 Liters of air/minute and should solely act as a port to deliver medication should it be needed during surgery.Last semester a prototype adaptor was produced that is universally compatible with all aerosolized medication canisters and also compatible with a specific gas sampling Luer port. It acts as a syringe to dispense medication in a simple fashion, with one hand, into the Luer port. This semester’s objectives are: make the adaptor compatible with all Luer ports, adjust the size of the aperture at the distal end of the prototype for optimal medication delivery, and thoroughly test the prototype to ensure efficacy. The prototype will also be designed and constructed in a way such that it can be injection molded. Other objectives for the semester that put a spin on the “design” aspect of the class are: performing a market analysis of our adaptor, obtaining a design or utility patent, and licensing the technology to a medical supply company.Last Week’s Goals•Continue brainstorming and researching design alternatives•Meet with Professor Shauer (meeting was re-scheduled)•Meet with Professor Samuelson•Continue searching for funding options for patent costs (long-term)•Begin work on mid-semester report and presentation with design alternatives•Make various CAD models based on brainstormingAccomplishments•Decided on three design alternatives to optimize spray pattern•Met with Professor Jay Samuelson, Professor Glenn Bower, and Professor Rolf Feitz •Began working on mid-semester powerpoint presentationThis Week’s Goals•Continue searching for funding options for patent costs (long-term)•Finish mid-semester report and presentation•Make various CAD models based on brainstorming•Begin researching testing options and contact the physics shop for quotes on new designProject Difficulties…ActivitiesOzair Chaudhry! 10.09.2009!
