The reflux of stomach acid into the esophagus is one of the most common GI ailments. One consequence of such reflux is the formation of scar tissue which forms abnormally stiff regions of esophageal tissue, sometimes leading to obstructive swallowing disorders. There are very few methods for either diagnosing or treating this disorder. There are two different measures which would be useful from a clinical point of view:
Team Members:
5/10-Poster Presentation
5/3-Finialize prototype, ask about interface
4/26-Found all components, including pump, pressure sensor, and tubing. Plan on putting it together today.
4/19-Found pressure sensor from Professor Webster and online from Digikey. We will go and look for a water pump this afternoon, one that pumps out water slow and at a constant rate. By next week we plan on having all of the protype parts and start to put it together.
4/12-Discussed both volume pump and pressure transducer. Plan meeting with Prof. Beebe to discuss volume pump and pressure transducer to where they would come from and if any are available. Try to set up meeting with Dr. Reichelderfer to exchange ideas about mid-semseter presentation.
3/14-Finished midsemester presentation and paper, will be presenting
3/8-Divide up paper and presentation for next week. Revise PDS. Set up meeting for next week to put paper and presentation together.
2/29- Brainstorm ideas on different mechanisms to measure size an compliance of the stricture. Met with Mark and discussed current ways of measuring tissue compliance, receive articles on measuring compliance inside the esophagus using balloons.
