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:! September 25 to October 2, 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•Contact Professor Shauer (aerosol) and Professor Samuelson (injection molding)•Organize ideas for getting funding •Submit CAD model to rapid prototyping company for preliminary quote•Continue brainstorming design alternatives•Contact Boehringer for general information on how they obtained rights to produce and distribute the Bronchodilator Tee (invented by doctor on campus)•Start project websiteSummary of Accomplishments•Set up meeting with Professor Shauer (10/02)•Contacted Boehringer labs via telephone but were not able to get any information on Bronchodilator Tee•Brainstormed new design alternatives for nozzle piece on prototype•Continued brainstorming and researching individuallyThis Week’s Goals•Continue brainstorming and researching design alternatives•Meet with Professor Shauer (10/02)•Organize questions and meet with Professor Samuelson to ask about material choice and injection molding•Continue searching for funding options for patent costs (long-term)Project Difficulties…ActivitiesOzair Chaudhry! 9.25.2009!Team meeting! ! 2.00 hr! 9.25.2009!Group brainstorming session! 1.50 hr!! ~~~~~~~!
